         promptly to Seller any balance properly allocable to Seller's period of
         ownership. Purchaser shall

                                        5



         bill and use commercially reasonable efforts to collect such Rent
         arrearages in the ordinary course of business, but shall not be
         obligated to engage a collection agency or take legal action to collect
         any Rent arrearages.

                           (b)      After the Closing, Seller shall continue to

         Seller to collect such Rents and to take all steps, whether before or
         after the Closing Date, as may be reasonably necessary to carry out the
         intention of the foregoing, including, without limitation, the delivery
         to Seller, upon demand, of any relevant books and records, the
         execution of any and all consents or other documents, and the
         undertaking of any action reasonably necessary for the collection of
         such Rents by Seller.

                  (vi)     the cost of all materials, supplies and other items
purchased and paid for by Seller for the Property in the ordinary course of
business which are not in use and are not in damaged or unusable condition as at
the date of the Closing, and the cost of all such supplies ordered for the
Property in the ordinary course of business and paid for in whole or in part by
Seller, but not received by the date of the Closing. Prior to conducting any
inventory of such items Seller shall give Purchaser reasonable advance notice
and an opportunity to be present during the performance of the inventory. At the
Closing, Purchaser shall reimburse Seller for the cost of all such supplies
previously paid for by Seller and shall assume the costs of all such supplies
ordered in the ordinary course of business and not paid for by Seller;

                  (vii)    wages, payroll taxes, welfare benefits, vacation pay
and other fringe benefits (in accordance with the applicable union contract, if

                  (viii)   charges payable under the Service Contracts with
respect to the Property which are assumed by Purchaser; and

                  (ix)     all other items customarily apportioned in connection
with the sale of properties similar to the Property in the State of Texas.

         4.5      Seller shall cause all electricity, gas and other utility
meters to be read on the day preceding the Adjustment Date, or as close thereto
as may be reasonably possible, and shall pay all bills rendered as a result of
such readings. The cost of such utilities for the period, if any, between the
date of the meter reading and the Adjustment Date shall be adjusted on the basis
of the most recently issued bill therefor. If Seller does not obtain such a
meter reading for any such utility, the adjustment therefor shall be on the
basis of the most recently issued bill therefor. At the Closing, Purchaser shall
reimburse Seller in an amount equal to all deposits, if any, made by Seller with
any utility company which will remain on deposit for the benefit of Purchaser
subsequent to the

                                        6



Closing, notwithstanding any provision in this Section 4.5 to the contrary.
Notwithstanding any provision in this Section 4.5 to the contrary, Seller will
not be required to obtain meter readings for any utilities for which Tenants are
directly liable for the payment thereof.

         4.6      The amount of any unpaid taxes, water charges and sewer rents
which Seller is obligated to pay and discharge, with the interest and penalties
thereon to a date not less than two business days after the Closing Date, may at
the option of Seller be allowed to Purchaser out of the Purchase Price, provided
official bills therefor with interest and penalties thereon figured to said date
are furnished by Seller at the Closing.

                                    COVENANTS
                                    ---------

         5.1      Purchaser shall pay at the Closing all recording and filing
fees and charges, and all survey charges and Seller shall pay all title
insurance charges. No part of the Purchase Price hereunder will be paid by
Purchaser for the personal property transferred hereunder. However, if any part
of the Purchase Price is deemed by any governmental or administrative body to
have been paid for such personal property, Purchaser will be solely responsible
for the sales tax (if any) payable in connection therewith and will indemnify
Seller therefor and against any claim, liability or damage resulting from any
obligations arising from Purchaser's failure to pay the amount of any such sales
tax. Each party shall pay the fees and disbursements of its own counsel. The
provisions of this Article 5 shall survive the Closing.

         5.2      From the date hereof until the Closing, Seller shall continue
to operate the Property in the ordinary course consistent with past practice.

                                    ARTICLE 6
                       DAMAGE OR DESTRUCTION; CONDEMNATION
                       -----------------------------------

         6.1      If by reason of fire or other casualty a Material (hereinafter
defined) portion of the buildings and improvements located on the Property shall
be destroyed or significantly damaged (the "LOSS") prior to the Closing then
Purchaser may by notice given no later than 10 business days after Seller has
given Purchaser notice of the Loss, terminate this Agreement, in which event
this Agreement shall become null and void and neither party hereto shall have
any rights or obligations to the other hereunder or by reason hereof, other than
those provisions of this Agreement which specifically survive the termination of
this Agreement.

         6.2      If Purchaser has not elected to terminate this Agreement, if
permitted to do so under Section 6.1, or if, at any time from the date hereof
until the Closing a portion of the buildings and improvements located on the
Property which is not Material shall be damaged or destroyed, neither party
shall have the right to terminate this Agreement as a result of such damage or
destruction and the purchase price shall not be reduced on account thereof;
PROVIDED, HOWEVER, that Seller will assign, transfer and convey to Purchaser all
of Seller's right, title and interest in and to any insurance

                                        7



proceeds that may be made or paid to Seller for the portion of the buildings and
improvements located on the Property so damaged or destroyed. If all or any
portion of such insurance proceeds has already been received by Seller, then the
amount so received (less the costs of collection, if any, and any expenses
incurred by Seller for the temporary protection and/or restoration of the
Property) shall be paid or allowed to Purchaser at the Closing, without
interest.

         6.3      As used herein, a loss shall be deemed Material if 10% or more
of the buildings and improvements located on the Property are destroyed or
significantly damaged.

                                    ARTICLE 7
                                  MISCELLANEOUS
                                  -------------

         7.1      This Agreement may be terminated at any time prior to the
Closing:

                  (i)      by mutual written consent of Seller and Purchaser;

                  (ii)     by either Seller or Purchaser if the Closing shall
not have occurred by December 6, 2001; PROVIDED, HOWEVER, that the right to
terminate this Agreement pursuant to this clause 7.1(ii) shall not be available
to any party whose failure to perform any of its obligations under this
Agreement has been the cause of, or resulted in, the failure of the Closing to
occur on or before such date.

         7.2      In the event of a termination of this Agreement by either
party, as provided in this Section 7.1, this Agreement shall forthwith become
void and there shall be no liability or obligation on the part of either party
or their respective partners, except with respect to Article 5 and this Section
7.1. Nothing herein shall relieve any party of liability with respect to any
breach by any party hereto of this Agreement.

         7.3      This Agreement shall be governed by and construed in
accordance with the domestic laws of the State of Texas without giving effect to
any choice of law or conflict of law provision or rule (whether of the State of
Texas or any other jurisdiction) that would cause the application of the laws of
any jurisdiction other than the State of Texas.

         7.4      This Agreement and the instruments referred to herein embody
the entire agreement and understanding between the parties relating to the
subject matter hereof and may not be amended, waived or discharged except by an
instrument in writing executed by the party against whom enforcement of such
amendment, waiver or discharge is sought.

         7.5      This Agreement may be executed in counterparts, each of which
when so executed shall be deemed to be an original, and such counterparts shall
together constitute but one and the same instrument.

                                        8



         IN WITNESS WHEREOF, the parties have duly executed this Agreement the
