     6.    Debt  Coverage  Requirement.   Each  of  the  Phase  I
Agreement  and  the  Phase II Agreement are hereby  modified  and
amended by inserting therein the following new Section 5.21.

     "5.21     Debt Coverage Requirement.

          "(a)  In  the  event the Debt Coverage  Ratio  for  any
     applicable Calendar Period should be less than 1.20 to  1.0,
     and  unless  Borrower otherwise elects to pledge  Additional
     Collateral as provided in subsection (b) below then,  within
     fifteen  (15)  days  after written  notice  from  Lender  to
     Borrower,  Borrower shall prepay a portion of the Loan  (the
     "Curative  Amount") such that a minimum Debt Coverage  Ratio
     of  1.20  to  1.0 or more is created based on (1) annualized
     Net  Operating Income for the immediately preceding Calendar
     Period  and (2) a hypothetical Debt Service Requirement  for
     the  then current Calendar Period which would result from  a
     reamortization  of  such  reduced  balance   of   the   Loan
     sufficient  to  fully amortize such Loan on a  level-payment
     basis  in  25  years  from the first  day  of  such  current
     Calendar  Period based on the Amortization Rate (as  defined
     below).   Irrespective  of  any  hypothetical  Debt  Service
     Requirement  utilized to calculate the Curative Amount,  the
     actual amount of the required payments shall continue to  be
     as provided in the Note.  Failure of Borrower to timely fund
     any  required Curative Amount shall be deemed an  "Event  of
     Default" pursuant to this Agreement in addition to any other
     "Events of Default" specified herein.

          "(b)  As  an  alternative to payment  of  the  Curative
     Amount,  Borrower shall be entitled, in the event  the  Debt
     Coverage  Ratio for any Calendar Period should be determined
     to be less than 1.20 to 1.0, to pledge additional collateral
     to  secure  the  Loan.  The collateral to be so  pledged  to
     Lender must be in the form of cash, certificates of deposit,
     letters  of  credit,  stocks, bonds or other  highly  liquid
     investments acceptable in all respects to Lender in its sole
     and absolute discretion (for purposes of this Agreement, the
     term  "Additional Collateral" shall mean and refer  to  such
     additional  collateral as shall be approved  by  Lender  and
     pledged  pursuant  to this subsection (b).   The  amount  or
     value  of  the Additional Collateral required to be  pledged
     shall  be  a  function  of  the liquidation  value  of  such
     collateral,  as  determined  by  Lender  in  its  reasonable
     discretion,  and shall be such amount (i.e., the liquidation
     value)  as  would, if subtracted from the  total  amount  of
     indebtedness evidenced and represented by the Note  at  such
     time,  result  in  a  Debt  Coverage  Ratio  (calculated  as
     provided  above)  equal to 1.20 to 1.0.  In connection  with
     such  pledge  of Additional Collateral, and not  later  than
     fifteen  (15)  days  after written  notice  from  Lender  to
     Borrower of Borrower's obligation to either pay the Curative
     Amount  or to pledge the Additional Collateral, and provided
     that  Borrower  has  not instead paid  the  Curative  Amount
     required  at  that  time pursuant to subsection  (a)  above,
     Borrower shall execute and deliver to Lender all pledge  and
     security   agreements,   financing  statements   and   other
     instruments,  certificates and agreements  as  Lender  shall
     require,   and  shall  deliver  to  Lender  the   Additional
     Collateral     or     such    instruments,     certificates,
     acknowledgments,  stock  powers, authorizations,  powers  of
     attorney,  consents and any and all other documentation,  as
     executed  by all appropriate parties as may be necessary  to
     effectuate  the  collateral pledge and  assignment  of  such
     collateral  to Lender, as Lender and its counsel shall  deem
     necessary   or   appropriate.   If,  after  the   Borrower's
     provision of Additional Collateral, the Debt Coverage  Ratio
     should  improve  so as to be 1.20 to 1.0  or  more  for  any
     Calendar  Period (without taking into account the Additional
     Collateral), then Borrower shall be entitled to a release of
     the  Additional  Collateral.  Borrower shall  thereafter  be
     required  to  either  pay to Lender the Curative  Amount  or
     repledge  Additional Collateral to the extent  the  required
     Debt  Coverage  Ratio  should fail  to  be  met  during  any
     subsequent Calendar Period and shall likewise be entitled to
     a  re-release  of  any such subsequently pledged  Additional
     Collateral   consistent   with  the  immediately   preceding
     sentence.

          "(c)  The  Debt  Coverage Ratio  calculation  shall  be
     undertaken  for  the applicable Calendar  Period.   Borrower
     shall  provide  written  evidence and  documents  to  Lender
     indicating the calculations and backup information  for  the
     Debt  Coverage  Ratio for each applicable  Calendar  Period.
     Lender  shall be entitled to request and require such backup
     documentation, including financial information,  as  may  be
     required  by  Lender in order to satisfy itself  as  to  the
     correct  calculation  of  the Debt Coverage  Ratio  for  any
     Calendar Period

          "(d)  As  used  in this Agreement, the following  terms
     have the following meanings:

               (1)   Calendar  Period:  The  three  (3)  calendar
          month  period (or portion thereof for the first period)

          December 31.

               (2)   Debt  Coverage Ratio:  Net Operating  Income
          for   a   Calendar  Period  divided  by  Debt   Service
          Requirements for the same Calendar Period.

               (3)   Debt  Service Requirements:  The greater  of
          (A)   any   and  all  principal  or  interest  payments
          scheduled  with respect to the Loan to the extent  such
          are  to  be  due and owing during such Calendar  Period
          (and  irrespective of whether or not such payments were
          timely made) or (B) all principal and interest payments
          which  would be owing during such Calendar Period based
          upon  a  hypothetical level-payment, mortgage loan-type
          amortization schedule of 25 years calculated using  the
          Loan  Amount, and an interest rate on the  Loan  Amount
          during the Calendar Period equal to the greater of  (i)
          the then actual Applicable Base Rate (as defined in the
          Note), or (ii) eight percent (8%), or (iii) the sum  of
          (x) the yield of the United States Treasury obligations
          which  shall have the closest maturity date (month  and
          year) to the date that is ten (10) years from the  date
          of  such  calculation plus (y) two percent (2.0%)  (the
          greater  of  clauses  (i), (ii)  or  (iii)  immediately
          preceding  being sometimes referred to  herein  as  the
          "Amortization Rate").

               (4)   Gross Income:  For each applicable  Calendar
          Period actual rentals, revenues and other cash forms of
          consideration,  received by, or  paid  to  or  for  the

          from  or  attributable  to the operation,  leasing  and
          occupancy  of the Mortgaged Property, determined  on  a
          cash basis (except as specified herein), including  the
          following:  (i) rents by any lessees or tenants of  the
          Mortgaged Property; (ii) rents and receipts received by
          or for the benefit of Borrower with respect to the full

          (iii)  proceeds  received by  or  for  the  benefit  of

          security  and  other type deposits and advance  rentals
          relating  to  the  Mortgaged Property which  have  been
          forfeited.   Notwithstanding anything  included  within
          this  definition  of  Gross  Income,  there  shall   be
          excluded  from  Gross Income the  following:   (i)  any
          security  or  other  deposits of lessees  and  tenants,

          forfeited;  (ii)  the  proceeds  of  any  financing  or
          refinancing  with respect to all or  any  part  of  the

          the current calendar year has not been made, then until
          such assessment has been made (and with any retroactive

     7.    Extension  Options.   If, but  only  if,  all  of  the
following  conditions precedent shall have been first  satisfied,
then Borrower shall be entitled, for one time only, to extend the
Maturity Date of the 6.6 Note, or the 7.7 Note, or both,  as  the
case  may be, by an additional twelve (12) months, to August  24,
2003.   The  conditions precedent to extension of the  either  or
both of the 6.6 Note and 7.7 Note for such additional twelve (12)
month period are as follows:

          (a)   Borrower  shall notify Lender in  writing  on  or
     before July 15, 2003, of Borrower's election to exercise its
     rights under this Section 7 and specify the note or notes to
     which such election applies.

          (b)   Borrower shall pay to Lender in cash an extension
     fee  equal to twenty-five one-hundredths percent (0.25%)  of
     the outstanding principal balance, as of August 23, 2002, of
     the 6.6 Note, the 7.7 Note, or both, as the case may be.

          (c)    Lender  shall  have  received  tenant   estoppel
     certificates dated not earlier than July 15, 2002, from  all
     tenants  under  the  Leases in effect at  that  time,  which
     certificates shall reasonably be satisfactory to  Lender  in
     form and substance.

          (d)   No Default or Event of Default shall exist on any
     of the Loan Documents.

          (e)   No event, claim, liability or circumstance  shall
     exist which, in Lender's determination, could be expected to
     have or have had a Material Adverse Effect.

          (f)   Borrower and Guarantor shall execute and  deliver
     to   Lender   such  modification,  renewal   and   extension
     agreements  and  other instruments as Lender may  reasonably
     request to evidence the extension of the Maturity Date.

          (g)    Lender  is  in  receipt  of   written   evidence
     satisfactory  to  Lender indicating that the  Debt  Coverage
     Ratio is being satisfied.

          (h)    Lender   is  in  receipt  of  written   evidence
     reasonably  satisfactory  to  Lender  that  the  outstanding
     principal amount of the 6.6 Note, the 7.7 Note, or both,  as
     the  case may be, is not more than seventy percent (70%)  of
     the fair market value of the Property that will continue  to
     secure the 6.6 Note, the 7.7 Note, or both, as the case  may
     be,  as  established in the appraisals received and accepted
     by Lender as of the date of this Agreement, such evidence to
     include   new   appraisals  of  the  Property  obtained   at
     Borrower's sole expense if Lender requires the same.

     8.    Title Insurance.  Contemporaneously with the execution
and  delivery hereof, the Borrower shall cause the Title  Company
to  issue  such  endorsements to the Title Policy as  Lender  may
reasonably require.

     9.     Acknowledgment  by  Borrower.   Except  as  otherwise
specified  herein, the terms and provisions hereof  shall  in  no
manner   impair,   limit,  restrict  or  otherwise   affect   the
obligations  of  Borrower  or  any  third  party  to  Lender,  as
evidenced  by  the Loan Documents.  Borrower hereby acknowledges,
agrees  and  represents that (i) Borrower is indebted  to  Lender
pursuant  to  the  terms of the 6.6 Note and  the  7.7  Note,  as
modified   hereby;  (ii)  the  liens,  security   interests   and
assignments  created  and evidenced by the  Loan  Documents  are,
respectively, valid and subsisting liens, security interests  and
assignments of the respective dignity and priority recited in the
Loan Documents; (iii) there are no claims or offsets against,  or
defenses or counterclaims to, the terms or provisions of the Loan
Documents, and the other obligations created or evidenced by  the
Loan Documents; (iv) Borrower has no claims, offsets, defenses or
counterclaims arising from any of Lender's acts or omissions with
respect   to  the  Property,  the  Loan  Documents  or   Lender's
performance  under  the Loan Documents or  with  respect  to  the
Property; (v) the representations and warranties contained in the
Loan   Documents   are  true  and  correct  representations   and
warranties  in  all  material respects of  Borrower  and  to  the
knowledge  of  Borrower, of any third parties,  as  of  the  date
hereof;  and  (vi)  Lender is not in default  and  no  event  has
occurred  which, with the passage of time, giving of  notice,  or
both,   would   constitute  a  default  by  Lender  of   Lender's
obligations under the terms and provisions of the Loan Documents.
To  the extent Borrower now has any claims, offsets, defenses  or
counterclaims against Lender or the repayment of all or a portion
of  the Loan, whether known or unknown, fixed or contingent, same
are  hereby  forever  irrevocably waived and  released  in  their
entirety.

     10.   No Waiver of Remedies.  Except as may be expressly set
forth   herein,   nothing  contained  in  this  Agreement   shall
prejudice,  act as, or be deemed to be a waiver of any  right  or
remedy  available  to  Lender  by reason  of  the  occurrence  or
existence  of  any  fact, circumstance or  event  constituting  a
default under the Note or the other Loan Documents.

     11.   Joinder  of  Guarantor.  By  its  execution  hereof  ,
Guarantor  hereby (i) acknowledges and consents to the terms  and
provisions  hereof; (ii) ratifies and confirms each  of  the  6.6
Guaranty  and the 7.7 Guaranty, including all interest and  costs
of collection, to or for the benefit of Lender; (iii) agrees that
each of the 6.6 Guaranty and the 7.7 Guaranty is and shall remain

each  of  the 6.6 Guaranty and the 7.7 Guaranty cover and pertain
to  the Loan Documents as modified hereby; (iv) acknowledges that
there   are  no  claims  or  offsets  against,  or  defenses   or
counterclaims to, the terms and provisions of either of  the  6.6
Guaranty or the 7.7 Guaranty or the other obligations created and
evidenced  by  each  of the 6.6 Guaranty and  the  7.7  Guaranty;
(v)  certifies that the representations and warranties  contained
in  each of the 6.6 Guaranty and the 7.7 Guaranty remain true and
correct  representations and warranties of Guarantor  as  of  the
date hereof; and (vi) acknowledges that Lender has satisfied  and
performed  its covenants and obligations under  each of  the  6.6
Guaranty  and the 7.7 Guaranty and the other Loan Documents,  and
that  no action or failure to act by or on behalf of, Lender  has
or  will  give rise to any cause of action or other claim against
Lender  for  breach  of either of the 6.6  Guaranty  or  the  7.7
Guaranty or other Loan Documents or otherwise.

     12.    Costs  and  Expenses.   Contemporaneously  with   the

shall  execute  or procure and deliver to Lender such  other  and
further   documents  and  instruments  evidencing,  securing   or
pertaining  to  the  Loan  or  the Loan  Documents  as  shall  be
reasonably  requested by Lender so as to evidence or  effect  the
terms  and  provisions hereof.  Upon Lender's  request,  Borrower
shall  cause  to  be delivered to Lender an opinion  of  counsel,
satisfactory  to  Lender  as  to form,  substance  and  rendering

Agreement  and  the terms and provisions hereof,  and  any  other
agreement   executed   in   connection   with   the   transaction
contemplated  hereby;  (ii) the authority of  Borrower,  and  any
constituents of Borrower, to execute, deliver and perform its  or
their  respective obligations under the Loan Documents, as hereby
modified; and (iii) such other matters as reasonably requested by
Lender.

     14.   Effectiveness  of  the  Loan  Documents.   Except   as
expressly  modified by the terms and provisions hereof,  each  of
the  terms  and  provisions  of the  Loan  Documents  are  hereby
ratified  and  shall remain in full force and  effect;  provided,
however, that any reference in any of the Loan Documents  to  the
Loan, the amount constituting the Loan, any defined terms, or  to
any  of the other Loan Documents shall be deemed, from and  after
the  date  hereof, to refer to the Loan, the amount  constituting
the  Loan,  defined  terms and to such other Loan  Documents,  as
modified hereby.

     15.   Governing Law.  THE TERMS AND PROVISIONS HEREOF  SHALL
BE  GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF  THE
STATE OF TEXAS, EXCEPT AS OTHERWISE EXPRESSLY PROVIDED HEREIN.

     16.  Time.  Time is of the essence in the performance of the
covenants contained herein and in the Loan Documents.

     17.   Binding  Agreement.  This Agreement shall  be  binding
upon  the successors and assigns of the parties hereto; provided,
however,  the  foregoing  shall not be  deemed  or  construed  to
(i)  permit, sanction, authorize or condone the assignment of all
or  any  part of the Property or any of Borrower's rights, titles
or  interests  in  and to the Property or any rights,  titles  or
interests  in and to Borrower, except as expressly authorized  in
the  Loan  Documents, or (ii) confer any right,  title,  benefit,
cause  of action or remedy upon any person or entity not a  party
hereto, which such party would not or did not otherwise possess.

     18.  Headings.  The section headings hereof are inserted for
convenience  of reference only and shall in no way alter,  amend,
define  or be used in the construction or interpretation  of  the
text of such section.

     19.  Construction.  Whenever the context hereof so requires,
reference  to the singular shall include the plural and likewise,
the  plural  shall  include the singular; words  denoting  gender
shall be construed to mean the masculine, feminine or neuter,  as
appropriate;  and  specific enumeration  shall  not  exclude  the
general,  but  shall be construed as cumulative  of  the  general
recitation.

     20.   Severability.   If  any clause or  provision  of  this
Agreement  is  or should ever be held to be illegal,  invalid  or
unenforceable under any present or future law applicable  to  the
terms hereof, then and in that event, it is the intention of  the
parties hereto that the remainder of this Agreement shall not  be
affected  thereby,  and  that in lieu  of  each  such  clause  or
provision   of  this  Agreement  that  is  illegal,  invalid   or
unenforceable,  such  clause  or provision  shall  be  judicially
construed  and  interpreted to be as  similar  in  substance  and
content  to  such  illegal, invalid or  unenforceable  clause  or
provision, as the context thereof would reasonably suggest, so as
to thereafter be legal, valid and enforceable.

     21.   Counterparts.  To facilitate execution, this Agreement
may  be executed in as many counterparts as may be convenient  or
required.   It  shall  not be necessary that  the  signature  and
acknowledgment  of,  or on behalf of, each  party,  or  that  the
signature and acknowledgment of all persons required to bind  any
party,  appear  on  each  counterpart.   All  counterparts  shall
collectively  constitute a single instrument.  It  shall  not  be
necessary in making proof of this Agreement to produce or account
for  more  than  a single counterpart containing  the  respective
signatures  and acknowledgment of, or on behalf of, each  of  the
parties  hereto.  Any signature and acknowledgment  page  to  any
counterpart  may  be  detached  from  such  counterpart   without
impairing  the legal effect of the signatures and acknowledgments
thereon  and thereafter attached to another counterpart identical
thereto  except  having attached to it additional  signature  and
acknowledgment pages.

     22.   THIS MODIFICATION AND THE OTHER LOAN DOCUMENTS  EMBODY
THE  FINAL, ENTIRE AGREEMENT AMONG THE PARTIES HERETO AND THERETO
AND   SUPERSEDE  ANY  AND  ALL  PRIOR  COMMITMENTS,   AGREEMENTS,
REPRESENTATIONS,  AND UNDERSTANDINGS, WHETHER  WRITTEN  OR  ORAL,
RELATING TO THE SUBJECT MATTER HEREOF AND THEREOF AND MAY NOT  BE
CONTRADICTED OR VARIED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS,  OR
SUBSEQUENT  ORAL AGREEMENTS OR DISCUSSIONS OF THE PARTIES  HERETO
OR  THERETO.   THERE  ARE NO ORAL AGREEMENTS  AMONG  THE  PARTIES
HERETO  OR THERETO.  THE PROVISIONS OF THIS MODIFICATION AND  THE
OTHER  LOAN  DOCUMENTS  MAY  BE AMENDED  OR  WAIVED  ONLY  BY  AN
INSTRUMENT  IN WRITING SIGNED BY THE RESPECTIVE PARTIES  TO  SUCH
DOCUMENTS.
