               ------------------------------------------------------------
     City, state, county, and school district ad valorem taxes, utility charges
     and other operating expenses are not being prorated between Seller and
     Cinemark, but rather will be adjusted between Cinemark and Seller at such
     time as the year's operating expenses are known and it is determined what,
     if any, is to be passed on to the tenants based upon their respective
     expense stops.  If as a result of any such adjustment an amount shall be
     owing between Seller and Cinemark, the same shall be adjusted between
     Seller and Purchaser, so that Purchaser shall pay any amount owing by
     Seller to Cinemark and shall receive any amount due to Seller from
     Cinemark.  This agreement to adjust shall survive Closing.

     15.  Purchaser's Default. In the event purchaser fails to close, Seller's
          -------------------

     16.  Seller's Default.  In the event Seller fails to close or otherwise
          ----------------
defaults with respect to Closing obligations, (i) Purchaser shall have the right
to terminate this Agreement by giving written notice of such termination to
Seller, whereupon Purchaser and Seller shall have no further rights,
obligations, or liabilities hereunder, except as may be expressly provided to
the contrary herein; or (ii) Purchaser shall have the right to accept title to
the Property subject to defects and objections with no reduction in the Purchase
Price (except for monetary encumbrances, other than the First Loan Documents,
arising by, through or under Seller), in which event such defects and objections
shall be deemed "Permitted Exceptions;"

                                    Page 11

<PAGE>

or (iii) Purchaser may elect to seek specific performance of this Agreement.
Purchaser shall not be limited with respect to any matters expressly surviving
the closing.

     17.  Condemnation.  If, prior to the Closing, all or any part of the
          ------------
Property is subjected to a bona fide threat of condemnation by a body having the
power of eminent domain or is taken by eminent domain or condemnation (or sale
in lieu thereof), or if Seller has received notice that any condemnation action
or proceeding with respect to the Property is contemplated by a body having the
power of eminent domain, Seller shall give Purchaser immediate written notice of
such threatened or contemplated condemnation or of such taking or sale, and
Purchaser may by written notice to Seller given within thirty (30) days of the
receipt of such notice from Seller, elect to cancel this Agreement. If Purchaser
chooses to cancel this Agreement in accordance with this Paragraph 17, then the
rights, duties, obligations, and liabilities of the parties hereunder shall
immediately terminate and be of no further force and effect. If Purchaser does
not elect to cancel this Agreement in accordance herewith, this Agreement shall
remain in full force and effect and the sale of the Property contemplated by
this Agreement, less any interest taken by eminent domain or condemnation, or
sale in lieu thereof, shall be effected with no further adjustment and without
reduction of the Purchase Price, and at the Closing, Seller shall assign,
transfer, and set over to Purchaser all of the right, title, and interest of
Seller in and to any awards that have been or that may thereafter be made for
such taking.

     18.  Damage or Destruction.  If any of the Improvements shall be destroyed
          ---------------------
or damaged prior to the Closing, and the estimated cost of repair or replacement
exceeds Five Hundred Thousand Dollars ($500,000.00) or if a Lease shall
terminate as a result of such damage, Purchaser may, by written notice given to
Seller within twenty (20) days after receipt of written notice from Seller of
such damage or destruction, elect to terminate this Agreement, in which event,
except as expressly provided herein to the contrary, the rights, duties,
obligations, and liabilities of all parties hereunder shall immediately
terminate and be of no further force or effect. If Purchaser does not elect to
terminate this Agreement pursuant to this Paragraph 18, or has no right to
terminate this Agreement (because the damage or destruction does not exceed
$500,000.00 and the Leases remain in full force and effect), and the sale of the
Property is consummated, Purchaser shall be entitled to receive all insurance
proceeds paid or payable to Seller by reason of such destruction or damage under
the insurance maintained by Seller (less amounts of insurance theretofore
received and applied by Seller to restoration). If the amount of said casualty
or rent loss insurance proceeds is not settled by the date of Closing, Seller
shall execute at Closing all proofs of loss, assignments of claim, and other
similar instruments to ensure that Purchaser shall receive all of Seller's
right, title, and interest in and under said insurance proceeds.

Agreement to an affiliate of Seller formed to take title to the Property.

     21.  Broker's Commission.  Purchaser and Seller hereby represent each to
          -------------------
the other that they have not discussed this Agreement or the subject matter
hereof with any real estate broker or agent other than The Roylston Group
("Broker"), which Seller agrees to pay pursuant to a separate agreement, so as
to create any legal right in any such broker or agent to claim a real estate
commission with respect to the conveyance of the Property contemplated by this
Agreement. Seller shall and does hereby indemnify and hold harmless Purchaser
from and against any claim, whether or not meritorious, for any real estate
sales commission, finder's fees, or like compensation in connection with the
sale contemplated hereby and arising out of any act or agreement of Seller.
Likewise, Purchaser shall and does hereby indemnify and hold harmless Seller
from and against any claim, whether or not meritorious, for any real estate
