     Purchase Agreement for Taco Cabana - San Antonio, TX
     
     
     
     (c)  Copies  of  an "as built" survey of the  Property  done
     concurrent with Seller's acquisition of the Property.
     
     (d)  Lease  of  the Entire Property showing occupancy  date,
     lease   expiration  date,  rent,  and  Guarantys,  if   any,
     accompanied by such tenant financial statements as may  have
     been  provided most recently to Seller by the Tenant  and/or
     Guarantors.
     
     It is a contingency upon Seller's obligations hereunder that
two  (2)  copies  of  Co-Tenancy Agreement in the  form  attached
hereto  duly  executed by Buyer and Seller and  dated  on  escrow
Closing Date be delivered to the Seller on the Closing Date.

      Buyer may cancel this agreement for ANY REASON in its  sole
discretion  by  delivering a cancellation notice, return  receipt
requested,  to Seller and escrow holder before the expiration  of
any  Review  Period.  Such notice shall be deemed effective  only
upon receipt by Seller.  If this Agreement is not canceled as set
forth  above,  the  First Payment shall be non-refundable  unless
Seller shall default hereunder.

      If  Buyer  cancels this Agreement as permitted  under  this
Section,  except  for  any  escrow  cancellation  fees  and   any
liabilities  under sections 15(a) of this Agreement  (which  will
survive),  Buyer  (after execution of such  documents  reasonably
requested by Seller to evidence the termination hereof) shall  be
returned  its  First Payment, and Buyer will have  absolutely  no
rights,  claims  or interest of any type in connection  with  the
Property  or this transaction, regardless of any alleged  conduct
by Seller or anyone else.

      Unless this Agreement is canceled by Buyer pursuant to  the
terms  hereof, if Buyer fails to make the Second Payment,  Seller
shall   be  entitled  to  retain  the  First  Payment  and  Buyer
irrevocably will be deemed to be in default under this Agreement.
Seller  may, at its option, retain the First Payment and  declare
this Agreement null and void, in which event Buyer will be deemed
to  have canceled this Agreement and relinquish all rights in and
to  the  Property or Seller may exercise its rights under Section
14  hereof.   If  this Agreement is not canceled and  the  Second
Payment  is  made  when required, all of Buyer's  conditions  and
contingencies will be deemed satisfied.

7.  Escrow. Escrow shall be opened by Seller and funds  deposited
in  escrow upon acceptance of this Agreement by both parties. The
escrow  holder  will  be a nationally-recognized  escrow  company
selected by Seller. A copy of this Agreement will be delivered to
the  escrow holder and will serve as escrow instructions together
with the escrow holder's standard instructions and any additional
instructions required by the escrow holder to clarify its  rights
and  duties  (and  the  parties agree to  sign  these  additional
instructions).  If  there  is any conflict  between  these  other
instructions and this Agreement, this Agreement will control.

8.  Title.  Closing will be conditioned on the  commitment  of  a
title  company selected by Seller to issue an Owner's  policy  of
title  insurance, dated as of the close of escrow, in  an  amount
equal  to  the  purchase  price, insuring  that  Buyer  will  own
insurable  title  to  the Property subject  only  to:  the  title
company's  standard exceptions;  current real property taxes  and
assessments;  survey  exceptions;  the  rights  of   parties   in
possession pursuant to the lease defined in paragraph  11  below;
and  other  items of record disclosed to Buyer during the  Review
Period.

      Buyer shall be allowed five (5) days after receipt of  said
commitment  for examination and the making of any  objections  to
marketability thereto, said objections to be made in  writing  or
deemed  waived.  If any objections are so made, the Seller  shall
be  allowed eighty (80) days to make such title marketable or  in
the  alternative  to  obtain  a commitment  for  insurable  title
insuring over Buyer's objections.  If Seller shall decide to make
no  efforts to make title marketable, or is unable to make  title
marketable or obtain insurable title, (after execution  by  Buyer
of such documents reasonably


     Buyer Initieal: /s/ A. D
     Purchase Agreement for Taco Cabana - San Antonio, TX




requested  by Seller to evidence the termination hereof)  Buyer's
First Payment shall be returned and this Agreement shall be  null
and void and of no further force and effect.

     Pending correction of title, the payments hereunder required
shall  be postponed, but upon correction of title and within  ten
(10)  days  after written notice of correction to the Buyer,  the
parties shall perform this Agreement according to its terms.

9.  Closing Costs.  Seller will pay one-half of escrow fees,  the
cost  of  the  title  commitment and  any  brokerage  commissions
payable  except  those brokerage commissions incurred  by  Buyer.
The  buyer  will pay the cost of issuing a Standard Owners  Title
Insurance  Policy  in the full amount of the purchase  price,  if
Buyer desires to purchase the same.  Buyer will pay all recording
fees,  one-half of the escrow fees, and the cost of an update  to
the  Survey  in Sellers possession (if an update is  required  by
Buyer.)  Each party will pay its own attorney's fees and costs to
document and close this transaction.

10. Real Estate Taxes, Special Assessments and Prorations.

     (a)  Because the Entire Property (of which the Property is a
     part) is subject to a triple net lease (as further set forth
     in  paragraph 11(a)(i), the parties acknowledge  that  there
     shall  be no need for a real estate tax proration.  However,
     Seller  represents  that to the best of its  knowledge,  all
     real  estate  taxes and installments of special  assessments
     due  and  payable in all years prior to the year of  Closing
     have  been paid in full.  Unpaid levied and pending  special
     assessments  existing on the date of Closing  shall  be  the
     responsibility  of Buyer and Seller in proportion  to  their
     respective  Tenant in Common interests, pro-rated,  however,
     to  the  date  of closing; for the period prior to  closing,
     such  taxes  and  asessments shall be the responsibility  of
     Seller, if Tenant shall not pay the same.  Seller and  Buyer
     shall   likewise  pay  in  proportion  to  their   ownership
     interests  all  taxes  due and payable  in  the  year  after
     Closing  and  any unpaid installments of special assessments
     payable therewith and thereafter, if such unpaid levied  and
     pending  special assessments and real estate taxes  are  not
     paid by any tenant of the Entire Property.
     
     (b)   All income and all operating expenses from the  Entire
     Property  shall be prorated between the parties and adjusted
     by them as of the date of Closing.  Seller shall be entitled
     to  all  income  earned  and shall be  responsible  for  all
     expenses  incurred prior to the date of Closing,  and  Buyer
     shall  be entitled to its proportionate share of all  income
     earned and shall be responsible for its proportionate  share
     of  all  operating expenses of the Property incurred on  and
     after  the date of closing, if the same are not paid by  any
     tenant of the Entire Property.
     
11. Seller's Representation and Agreements.

     (a)  Seller represents and warrants as of this date that:

     (i)   Except  for the lease in existence between Seller  and
     Taco Cabana, Inc. ("Lessee"), dated July 19, 1991 which  was

     Assignment  and  Assumption of Leases between  Taco  Cabana,
     Inc. and TC Lease Holdings III, V and VI, Inc. dated October
     31,   1993  and  pursuant  to  the  General  Assignment  and
     Assumption of Leases between TC Lease Holding III V and  VI,

     Seller  is not aware of any leases of the Property.  A  copy
     of  the above referenced documents is incorporated herein as
     "Exhibit "B".   The
     
     
     
     Buyer Initieal: /s/ A. D

     (b)   Provided  that  Buyer performs  its  obligations  when
     required, Seller agrees that it will not enter into any  new
     contracts  prior  to the Closing Date that would  materially
     affect  the  Property  and be binding  on  Buyer  after  the
     Closing  Date without Buyer's prior consent, which will  not
     be  unreasonably withheld.  However, Buyer acknowledges that
     Seller retains the right both prior to and after the Closing
     Date  to  freely  transfer  all or  a  portion  of  Seller's
     remaining undivided interest in the Entire Property provided
     such sale shall not encumber the Property being purchased by

     intentional misconduct.
     
     (e)   Buyer agrees that it shall be purchasing the  Property
     in  its  then present condition, as is, where is, and Seller
     has  no  obligations to construct or repair any improvements

     adjustment  to  the Purchase Price, reduction or  abatement,

     in and to all insurance proceeds pro-rata in relation to the
