ITEM 2.   ACQUISITION OR DISPOSITION OF ASSETS.

          American Industrial Properties REIT, a Texas real estate investment
trust (the "Trust"), AIP-SWAG Operating Partnership, L.P., a Delaware limited
partnership (the "Operating Partnership") of which the Trust is the 98% general
partner, and Shidler West Investment Corporation, a Delaware corporation and
unrelated third party ("Shidler"), entered into a Contribution and Exchange
Agreement dated as of September 25, 1997 (the "Contribution Agreement").
Shidler, acting on behalf of AG Industrial Investors, L.P., a Delaware limited
partnership, and Shidler West Acquisition Company, LLC, a California limited
liability company (collectively, the "Contributor Parties"), owned the right to
purchase 783,780 square feet of industrial real property in the Dallas
metropolitan area (the "Merit Portfolio") pursuant to four separate purchase
agreements, as amended (the "Merit Agreements"), with Merit Industrial
Properties Limited Partnership, Merit 1995 Industrial Portfolio Limited
Partnership, Merit VV 1995 Industrial Portfolio Limited Partnership, and Merit
VV Land 1995 Industrial Portfolio Limited Partnership, all of which are Texas
limited partnerships (collectively, "Merit").  On October 3, 1997, pursuant to
the Contribution Agreement and the Assignment and Assumption of Purchase
Agreements dated as of October 3, 1997 between Shidler and the Operating
Partnership, Shidler, acting on behalf of the Contributor Parties, assigned to
the Operating Partnership all of its right, title and interest in and to the
Merit Agreements (the "Assignment").  The aggregate consideration for the
Assignment was $3,000,000, which was agreed upon through arm's length
negotiations between the Trust and Shidler.  As consideration for the
Assignment, (i) the Operating Partnership issued 179,085 (as adjusted for the
Trust's one for five reverse share split, which was effective on October 15,
1997 (the "Reverse Share Split")) units of limited partnership interest in the
Operating Partnership ("OP Units") (determined by dividing $2,740,000 by
$15.30, the agreed upon per share price of the Common Shares (as defined in
Item 5 below), as adjusted for the Reverse Share Split) to the Contributor
Parties and (ii) the Operating Partnership paid $260,000 in cash (from its cash
reserves) to Shidler to reimburse Shidler for certain costs it incurred
relating to the negotiation and performance of the Merit Agreements and as
consideration for Shidler's delivery and assignment to the Operating
Partnership and the Trust of documents, information and materials relating to
the properties in the Merit Portfolio.  Additionally, in exchange for the cash
payment of $2,000 by the Contributor Parties to the Trust, the Trust issued to
each of the Contributor Parties 20,000 warrants (the "Trust Warrants") to
purchase additional Common Shares at a purchase price of $17.50 per Common
Share (as adjusted for the Reverse Share Split).  The Trust Warrants are
exercisable by the Contributor Parties until October 3, 2000.

          Pursuant to the terms of the Amended and Restated Agreement of
Limited Partnership of the Operating Partnership dated as of October 3, 1997
(the "Partnership Agreement"), beginning on October 3, 1999, OP Units are
redeemable for cash, or at the election of the Trust as the general partner of
the Operating Partnership, Common Shares on a one-for-one basis (subject to
adjustments for mergers, reorganizations, recapitalizations, share dividends,
share splits and reverse share splits).  Pursuant to the terms of the
Partnership Agreement, the cash consideration to be paid upon redemption of OP
Units is based upon the average of the daily market price per Common Share on
the New York Stock Exchange for the 10 consecutive trading days prior to the
date the Trust receives





                                       1
<PAGE>   3
the redemption notice.  Each of the Contributor Parties was granted
registration rights with respect to the Common Shares they may acquire upon
exercise of the Trust Warrants and upon redemption of the OP Units.

          On October 3, 1997, pursuant to the terms of the Merit Agreements,
the Trust acquired, through the Operating Partnership, the Merit Portfolio,
which consists of 20 light industrial and warehouse/distribution buildings in
the Dallas, Texas metropolitan area for a total purchase price of $33.77
million in cash.  The purchase price was agreed upon through arm's length
negotiations between Shidler and Merit.  The purchase price was funded through
(i) approximately $20,675,000 million in borrowings under the Trust and
Operating Partnership's $35 million secured acquisition line with Prudential
Securities Credit Corporation (the "Secured Credit Line") and (ii)
approximately $13,100,000 from the cash proceeds received from the Private
Placements (as defined in Item 5 below).

          The acquisition of the Merit Portfolio more than doubles the Trust's
Dallas area portfolio, which now totals over 1.5 million square feet.  The
Merit Portfolio totals 783,780 square feet located in eight developments and is
currently 88% leased.  The Trust also acquired 5.82 acres of land for future
development.  The Merit Portfolio contains a mix of light industrial and

          (3)    DFW IV.  DFW IV is located in the DFW/Freeport submarket and
contains 72,918 square feet of warehouse/distribution space.  The property is
91% leased to seven tenants.

          After the acquisition of the Merit Portfolio and the property
acquisitions described in Item 5 below, the Trust now owns, directly or through
the Operating Partnership, 22 real estate properties consisting of 21
industrial or warehouse/distribution developments and one enclosed specialty
retail mall.

ITEM 5.  OTHER EVENTS.

SECURED CREDIT LINE.

          The Trust and the Operating Partnership entered into a Credit
Agreement dated as of October 3, 1997 with Prudential Securities Credit
Corporation (the "Lender").  Under the Secured Credit Line, the Trust and the
Operating Partnership may borrow, on a joint and several basis, up to $35
million solely to finance the acquisition of the Merit Portfolio and additional
properties and the transaction and other costs related thereto.  The Secured
Credit Line is secured by properties acquired with the proceeds of any such
borrowings.  Any borrowings under the Secured Credit Line must be made prior to
October 3, 1998.

          The Secured Credit Line has a variable interest rated based on the
30-day LIBOR rate plus 200 basis points and a maximum loan to value ratio of
70%.  Interest is payable monthly.  Borrowings made under the Secured Credit
Line mature on October 3, 1998 and, if not repaid, allow the Lender to move
such borrowings into a securitized mortgage pool.  Borrowings made under the
Secured Credit Line are prepayable without penalty.

          The Trust and the Operating Partnership borrowed $20.675 million
under the Secured Credit Line to partially finance the acquisition of the Merit
Portfolio.  The Trust intends to refinance this borrowing prior to maturity
with proceeds from future permanent financings or equity offerings.

CENTRAL PARK OFFICE TECH AND SKYWAY CIRCLE SOUTH.

          On August 29, 1997, the Trust acquired Central Park Office Tech
("Central Park") and Skyway Circle South ("Skyway") from CM Property
Management, Inc., a Connecticut corporation.  Central Park is a 70,250 square
foot light industrial building located in Richardson, Texas, a headquarters
location for several technology and telecommunications companies.  Central Park
is situated on 4.80 acres and is 100% leased to 10 tenants, including Lam
Research and KLA-Tencor, both of which are involved in the semiconductor
industry.

<PAGE>   5
          The Trust purchased Central Park for $4,200,000 in cash.  The
purchase price was funded from the cash proceeds received from the private
placements of common shares of beneficial interest, par value $0.10 per share
("Common Shares"), in July 1997 (the "Private Placements").

          Skyway is a 67,015 square foot light industrial building located

amended, modified or supplemented, the "Leases").

2.     Purchase Price; Independent Contract Consideration.

              a.     The purchase price of the Property shall be Fourteen
Million Nine Hundred Ninety-Five Thousand Dollars ($14,995,000.00) (the
"Purchase Price").  The Purchase Price shall be paid to Seller at Closing, plus
or minus prorations and other adjustments hereunder, in immediately available
funds.

<PAGE>   2




              b.     The Purchase Price shall be paid as follows:

                     i.     Upon mutual execution of this Agreement, Purchaser
shall deliver to Commonwealth Land Title Company of Dallas ("Title Company") a
deposit in the amount of One Hundred Fifty Thousand Dollars ($150,000.00) (the
"Initial Deposit; and, together with the Extension Deposit (as defined below),
if applicable, the "Deposit").  The Deposit shall be held in an interest-
bearing account and interest accruing thereon shall be held for the account of
Purchaser.  In the event the sale of the Property as contemplated hereunder is
consummated, the Deposit plus interest accrued thereon shall be delivered to
Seller at the Closing and credited against the Purchase Price.

                     ii.    Prior to or contemporaneous with the execution
hereof by Purchaser and Seller, Purchaser has paid to Seller One Hundred
Dollars ($100.00) (the "Independent Contract Consideration"), which amount
Seller and Purchaser bargained for and agreed to as consideration for Seller's
execution and delivery of this Agreement.  The Independent Contract
Consideration is non-refundable and in addition to any other payment or deposit
required by this Agreement, and Seller shall retain the Independent Contract
Consideration notwithstanding any other provision of this Agreement to the
contrary; provided, however, that if the Closing shall occur hereunder, then
the Independent Contract Consideration shall be applied to the Purchase Price.

                     iii.   The balance of the Purchase Price shall be paid to
Seller at the closing of the purchase and sale contemplated hereunder (the
"Closing").

3.     Title to the Property.

              a.     At the Closing, Seller shall convey to Purchaser
indefeasible and insurable fee simple title to the Land and the Improvements,
by one or more duly executed and acknowledged special warranty deeds in the
form attached hereto as Exhibit C (collectively, the "Deed").  Evidence of
delivery of indefeasible and insurable fee simple title shall be the issuance
by Title Company to Purchaser of a Texas Owner's Policy of Title Insurance
(Form T-1) in the amount of the Purchase Price (the "Title Policy"), insuring
fee simple title to the Land and the Improvements in Purchaser, subject only to
such exceptions as Purchaser shall approve pursuant to Subparagraph 5(a) below
(the "Permitted Exceptions").  The Title Policy shall contain such special
endorsements as Purchaser may reasonably require, including, without
limitation, the amendment of the survey exception to read "shortages in area"
only (the "Endorsements").  The Title Company shall also provide for
reinsurance with direct access with such companies and in such amounts as
Purchaser shall reasonably request.

              b.     At the Closing, Seller shall transfer title to the
Personal Property and the Inventory by a bill of sale in the form attached
hereto as Exhibit D (the "Bill of Sale"), such title to be free of any liens,
encumbrances or interests, other than the Permitted Exceptions.

<PAGE>   3




              c.     At the Closing, Seller shall transfer title to the
Intangible Personal Property by an assignment of service contracts, warranties
and guaranties and other intangible property in the form attached hereto as
Exhibit E (the "Assignment of Intangible Property") and shall transfer title to
the Leases by an assignment of leases in the form attached hereto as Exhibit F
(the "Assignment of Leases"), such title to be free of any liens, encumbrances
or interests, other than the Permitted Exceptions.

4.     Due Diligence and Time for Satisfaction of Conditions.

       Purchaser shall have the right to commence due diligence with respect to
the Property following the date on which this Agreement is fully executed by
the parties hereto (the "Contract Date") and the due diligence period ("Due
Diligence Period") shall expire on July 30, 1997, provided, however, in the
event that Seller fails to deliver to Purchaser any of the items identified on
Exhibit G attached hereto and identified with an asterisk (the "Delivery
Items") on or before the date that is five (5) days after the Contract Date,
the Due Diligence Period shall be extended with respect to such undelivered
Delivery Item only by one day for each day beyond such fifth (5th) day until
such Delivery Item is delivered to Purchaser.  In addition to the foregoing,
Seller shall, upon 24 hours notice, make available to Purchaser and its
employees, representatives, counsel and consultants access to all of its books,
records and files relating to the Property in Seller's possession or reasonable
control, including, without limitation, all of the items set form on said
Exhibit G other than the Delivery Items, and Seller agrees, to the extent
reasonably feasible, to allow Purchaser to make copies at Seller's office or
the property management office of such items as Purchaser reasonably requests.
As used in this Agreement, the term "reasonable control" mean those items in
the possession of Seller's agents or independent contractors under direct
contract with Seller or its affiliates, and the term "affiliate" means any
entity or person controlled by, controlling or under common control with a
named person or entity.

5.     Diligence Period Conditions.

       The following conditions are precedent to Purchaser's obligation to
purchase the Property and to deliver the Purchase Price (the "Diligence Period
Conditions"):

              a.     Purchaser's review and approval of title to the Property,
as follows.  Seller shall deliver to Purchaser at Seller's sole cost and
expense, within five (5) days after the Contract Date, the following:

                     i.     one or more current standard coverage preliminary
title reports on the Land, issued by Title Company, accompanied by copies of
all documents referred to in the reports (the "Preliminary Reports").  In the
event the Title Company issues any supplements to the Preliminary Reports
during the term of this Agreement, Purchaser shall have five (5) business days
following delivery of any such supplemental report to approve or disapprove in
writing of any exception contained therein and not disclosed in the Preliminary
Reports, or any prior supplement thereto;





3
<PAGE>   4




                     ii.    copies of all existing and proposed easements,
covenants, restrictions, agreements or other documents which affect title to
the Property and which are not disclosed by the Preliminary Reports;

                     iii.   all surveys of the Land and Improvements in
Seller's possession or reasonable control; and

                     iv.    copies of the most recent property tax bills for
the Property.

       Purchaser shall advise Seller, at least ten (10) days prior to the end
of the Due Diligence Period, what exceptions to title, if any, will be accepted
by Purchaser.  Seller shall have five (5) days after receipt of Purchaser's
objections to give Purchaser:  (i) notice that Seller shall use all reasonable
efforts to remove all disapproved exceptions from title on or before the
Closing Date; or (ii) notice that Seller elects not to cause such exceptions to
be removed.  If Seller gives Purchaser notice under clause (ii), Purchaser
shall have five (5) days to elect to proceed with the purchase or terminate
this Agreement.  If Purchaser shall fail to give Seller notice of its election
within said five (5) days, Purchaser shall be deemed to have elected to
terminate this Agreement.  If Seller gives notice under clause (i) above and
fails to remove all such disapproved exceptions prior to the Closing Date
despite using its reasonable efforts and Purchaser is unwilling to accept title
subject to such exception in its sole and absolute discretion, Purchaser shall
have the right to terminate this Agreement.  Notwithstanding anything to the
contrary provided herein, Seller shall be obligated to remove or endorse over
to the reasonable satisfaction of Purchaser prior to Closing all monetary liens
encumbering the Property (or any portion thereof) other than the lien of any
property taxes, not yet due or payable.

              b.     Purchaser's review and approval of the matters described
in Paragraph 4 above and each component thereof as Purchaser shall desire in
its sole and absolute discretion.  Such review shall include an examination for
the presence or absence of Hazardous Material (as defined in Subparagraph 8(j)
below).  Notwithstanding anything to the contrary contained herein, Purchaser
shall not engage in or otherwise conduct any additional environmental studies
or environmental testing or sampling of any kind with respect to the Property
or with respect to the soils or ground water, or other studies which would
require test boring or which testing would otherwise damage or disturb any
portion of the Property, without obtaining Seller's prior written consent
thereto, which consent shall not be unreasonably withheld, delayed or
conditioned.

              c.     Purchaser's review and approval, within the Due Diligence
Period, of a schedule (the "Schedule of Agreements") setting forth an exclusive
list of all of the service contracts and similar agreements affecting the
Property.  Prior to the end of the Due Diligence Period, Purchaser shall
deliver to Seller a list setting forth those service contracts and similar
agreements that shall be assigned to, and assumed by, Purchaser at the Closing
(the "Assumed Contracts").  Purchaser shall have the right, in its sole
discretion, to require the termination of any service contract or similar
agreement that is





4


<PAGE>   5



not an Assumed Contract effective as of the Closing, provided that either (i)
such contract or agreement is terminable by Seller without the payment of any
fee or penalty and Purchaser provides to Seller adequate notice that Purchaser
shall require the termination of such contract or agreement or (ii) the service
provider is an affiliate of Seller or Seller's general partner.

              Prior to the end of the Due Diligence Period, Purchaser shall
deliver written notice (the "Approval Notice") to Seller informing Seller
whether or not Purchaser has approved or waived all of the Diligence Period
Conditions.  Notwithstanding anything in this Agreement to the contrary,
Purchaser shall have the right to terminate this Agreement at any time prior to
the end of the Due Diligence Period in its sole and absolute discretion and for
any or for no reason whatsoever.  If, by the end of the Due Diligence Period,
Purchaser shall not have delivered the Approval Notice to Seller approving or
waiving all of the Diligence Period Conditions, then this Agreement shall
automatically terminate, the Deposit shall be returned to Purchaser and the
parties shall be released from all obligations hereunder.

6.     Conditions to Closing.

       The following conditions are precedent to Purchaser's obligation to
acquire the Property and to deliver the Purchase Price (the "Conditions
Precedent"):

              a.     This Agreement shall not have terminated pursuant to any
other provision hereof, including, without limitation, Paragraph 5 above.

              b.     Seller's obtaining and delivering to Purchaser tenant
estoppel certificates from tenants ("Tenants") occupying all of the rentable
area of the leased premises in the Property that is leased to Tenants, which
certificates shall be in the form of Exhibit I attached hereto (subject only to
such changes and qualifications, including, without limitation, statements
alleging defaults or other matters, as are acceptable to Purchaser in its
reasonable discretion) and shall reflect the terms of the respective Leases,
and which certificates shall be dated (or recertified) no earlier than forty-
five (45) days prior to the Closing Date.  Seller shall deliver to each of the
Tenants of the Property, and shall use its reasonable efforts to obtain from
each of the Tenants, a tenant estoppel certificate in the form attached hereto
as Exhibit I, revised by Seller to reflect the terms of the respective Leases,
and modified to address reasonable, specific concerns arising as a result of
Purchaser's review of the Leases that are conveyed to Seller in writing prior
to the expiration of the Due Diligence Period.  As used in this Section 6(b),
reasonable efforts shall be limited to demand only and Seller shall not be
obligated to institute legal action to require delivery of such estoppel
certificates.  Notwithstanding the foregoing, to the extent that Seller has not
obtained satisfactory estoppel certificates from all of the Tenants despite its
using reasonable best efforts, but Seller has obtained satisfactory estoppel
certificates from all of the Major Tenants and from Tenants (including Major
Tenants) occupying ninety percent (90%) or more of the rentable area of the
leased premises in the Property that is leased to Tenants, then Seller shall
deliver to Purchaser a





5
<PAGE>   6



master landlord estoppel dated as of the Closing Date with respect to all
leased space in the Premises for which a satisfactory tenant estoppel
certificate is not delivered by Seller, which master estoppel certificate shall
be in form and substance (based substantially on Exhibit I hereto) reasonably
satisfactory to Purchaser, and the Condition Precedent set forth in this
Paragraph 6(b) shall be deemed satisfied.  The representations and warranties
set forth in Seller's master estoppel certificate shall survive the Closing as
to each such space until the scheduled expiration date of the current term of
the lease for such space.  In the event Seller shall deliver one or more
estoppel certificates, Seller shall have the right, after the Closing, to
continue to obtain estoppel certificates with respect to such leases.  In the
event Seller is able to obtain an estoppel certificate from a tenant for which
Seller delivered a replacement estoppel certificate, then the obligations of
the Seller under the replacement estoppel certificate shall terminate and be of
no further force or effect as of the date of delivery of the estoppel
certificate from the tenant.  As used herein, the term "Major Tenant" shall
mean a Tenant occupying 10,000 rentable square feet or more of leased space in
the Premises.

              c.     All of Seller's representations and warranties contained
in or made pursuant to this Agreement shall have been true and correct when
made and shall be true and correct as of the Closing Date.  At the Closing
Seller shall deliver to Purchaser a certificate certifying that each of
Seller's representations and warranties contained in Paragraph 8 below are true
and correct as of the Closing Date.  In the event that Seller advises Purchaser
prior to the Closing that any of Seller's representations or warranties set
forth herein is not true and correct as a result of an event occurring after
the Contract Date that is beyond the control of Seller or Seller's employees,
partners, agents or contractors, then Purchaser's sole remedy shall be to
cancel and terminate this Agreement and receive the return of the Deposit or to
waive the condition precedent set forth in this Paragraph 6(c) with respect to
such representation or warranty and, in the event the Closing occurs, Purchaser
shall not be entitled to any reduction in the Purchase Price or recover damages
from Seller with respect to such representation or warranty.  Notwithstanding
anything to the contrary set forth above, in the event that Purchaser advises
Seller prior to the Closing that any of Seller's representations or warranties
set forth herein is not true and correct, Seller shall have the right to elect
to cure such untrue or incorrect representation or warranty prior to the
Closing, and in the event that Seller cures all such untrue or incorrect
representations and warranties prior to the Closing, the Condition Precedent
set forth in this Paragraph 6(c) shall be deemed satisfied.  Seller shall have
the right to extend the Closing Date with respect to any affected Constituent
Parcel Constituent Parcel (as defined below) for up to sixty (60) days to cure
any such untrue or incorrect representations or warranties, provided that
Seller (i) delivers written notice to Purchaser within five (5) days after
Seller receives such notification from Purchaser, which notice shall state that
Seller is electing to extend the Closing Date and that Seller will use all
commercially reasonable efforts to cure such untrue or incorrect representation
or warranty, and (ii) thereafter diligently proceeds to attempt to cure all
such untrue or incorrect representations and warranties.  The sixty (60) day
period set





6


<PAGE>   7



forth in the immediately preceding sentence shall run concurrent with the sixty
(60) day period set forth in Paragraph 11(b) below.

              d.     The physical condition of the Property shall be
substantially the same on the day of Closing as on the date of Purchaser's
execution of this Agreement, reasonable wear and tear and loss by casualty
excepted (subject to the provisions of Paragraph 12 below), and, as of the day
of Closing, there shall be no litigation or administrative agency or other
governmental proceeding of any kind whatsoever, pending or threatened, which
after Closing would materially adversely affect the value of the Property or
the ability of Purchaser to operate the Property in the manner in which it is
currently being operated, and no proceedings shall be pending or threatened
which could or would cause the redesignation or other modification of the
zoning classification of, or of any building code requirements applicable to
the Property or any portion thereof.

              e.     Title Company shall be irrevocably and unconditionally
committed to issue to Purchaser the Title Policy as described in Subparagraph
3(a) above.

              The Conditions Precedent are intended solely for the benefit of
Purchaser.  Subject to the provisions of Paragraph 7(b) below, if any of the
Conditions Precedent is not satisfied, Purchaser shall have the right in its
sole discretion either to waive in writing such Condition Precedent without
reduction in the Purchase Price and proceed with the purchase or terminate this
Agreement, in which event the Deposit shall be returned to Purchaser and the
parties shall be released from all obligations hereunder.

              In the event that Purchaser consummates the Closing hereunder,
Purchaser shall be deemed to have waived any and all unsatisfied conditions
precedent.

7.     Remedies.

        a.    In the event the sale of the Property is not consummated because
of the failure of any condition or any other reason except a default under this
Agreement or any of the Other Agreements (as defined below) on the part of
Purchaser, the Deposit plus interest accrued thereon shall immediately be
returned to Purchaser.  If said sale is not consummated because of a default
under this Agreement or under any of the Other Agreements on the part of
Purchaser, the Deposit (but not the interest accrued thereon) shall be paid to
and retained by Seller as liquidated damages.  The parties have agreed that
Seller's actual damages, in the event of a default by Purchaser, would be
extremely difficult or impracticable to determine.  THEREFORE, BY PLACING THEIR
INITIALS BELOW, THE PARTIES ACKNOWLEDGE THAT THE DEPOSIT (AS WELL AS THE
DEPOSIT UNDER EACH OF THE OTHER AGREEMENTS) HAS BEEN AGREED UPON, AFTER
NEGOTIATION, AS THE PARTIES' REASONABLE ESTIMATE OF SELLER'S DAMAGES AND AS
SELLER'S EXCLUSIVE REMEDY AGAINST PURCHASER, AT LAW OR IN EQUITY, IN THE EVENT
OF A DEFAULT UNDER THIS AGREEMENT OR UNDER ANY OF THE OTHER AGREEMENTS ON THE
PART OF PURCHASER.  NOTWITHSTANDING THE FOREGOING PROVISIONS OF THIS





7
<PAGE>   8



PARAGRAPH 7(a), THIS PARAGRAPH 7(a) SHALL NOT LIMIT ANY RECOVERY BY SELLER
PURSUANT TO THE PROVISIONS OF PARAGRAPHS 13, 17(b), 17(h), AND 17(l) BELOW OR
PURSUANT TO THE PROVISIONS OF PARAGRAPHS 13, 17(b), 17(h), AND 17(l) OF ANY OF
THE OTHER AGREEMENTS.

              INITIALS:      Seller _______              Purchaser _______

        b.    In the event the sale of the Property is not consummated because
of a material default under this Agreement on the part of Seller or a material
default under any of the Other Agreements on the part of the "Seller"
thereunder, which default is not cured within three (3) business days after
receipt of written notice from Purchaser, or if a Condition Precedent cannot be
fulfilled because Seller frustrated such fulfillment by some willful act,
Purchaser may elect, as its sole and exclusive remedy hereunder, to either (1)
terminate this Agreement by delivery of notice of termination to Seller,
whereupon (A) the Deposit (as well as the Deposit under each of the Other
Agreements) plus interest accrued thereon shall be immediately returned to
Purchaser, and (B) Seller shall pay to Purchaser any title, escrow, legal and
inspection fees incurred by Purchaser and any other expenses incurred by
Purchaser in connection with the negotiation of this Agreement and the Other
Agreements and Purchaser's pursuit of the transactions contemplated hereunder
and under the Other Agreements and the performance of its due diligence review
of the Property and the "Property" described in the Other Agreements,
including, without limitation, environmental and engineering consultants' fees
and expenses and legal fees, and neither party shall have any further rights or
obligations hereunder, or (2) continue this Agreement pending Purchaser's
action for specific performance.

8.     Closing and Escrow.

       a.     Upon mutual execution of this Agreement, the parties hereto shall
deposit an executed counterpart of this Agreement with Title Company and this
Agreement shall serve as instructions to Title Company for consummation of the
purchase and sale contemplated hereby.  Seller and Purchaser agree to execute
such additional escrow instructions as may be appropriate to enable the escrow
holder to comply with the terms of this Agreement; provided, however, that in
the event of any conflict between the provisions of this Agreement and any
supplementary escrow instructions, the terms of this Agreement shall control.

        b.    The parties shall conduct an escrow Closing pursuant to this
Paragraph 8 on or before September 4, 1997 or on such other date as Purchaser
and Seller may agree in their sole and absolute discretion (the "Closing
Date"), provided, however, that Purchaser shall have the right to extend the
Closing Date on one or more occasions for up to thirty (30) days in the
aggregate so long as Purchaser (i) delivers written notice to Seller not less
than ten (10) business days prior to the then scheduled Closing Date, (ii)
deposits an





8


<PAGE>   9



additional One Hundred Ten Thousand Dollars ($110,000.00) (the "Extension
Deposit") in escrow with Title Company, and (iii) similarly extends the
"Closing Date" under each of the Other Agreements and deposits with Title
Company the "Extension Deposits" thereunder, and Seller shall have the right to
extend the Closing Date with respect to affected Constituent Parcels for up to
sixty (60) days as set forth in Paragraphs 6(c) and 11(b) hereof.  Upon deposit
with Title Company, the Extension Deposit shall be non-refundable, except to
the extent that this Agreement terminates as a result of a Seller default or
the failure of a condition to Closing for the benefit of Purchaser.

       c.     At or before the Closing, Seller shall deliver to Purchaser the
following:

              i.     the duly executed (and where appropriate acknowledged)
Deed, Bill of Sale, Assignment of Intangible Property and Assignment of Leases;

              ii.    duly executed estoppel certificates as required pursuant
to Subparagraph 8(b) above;

              iii.   originals of all Leases, Assumed Contracts, and building
permits, certificates of occupancy and plans and specifications for the
Improvements and all tenant-occupied space included within the Improvements to
the extent in Seller's possession or reasonable control;

              iv.    notices to the Tenants in form satisfactory to Purchaser,
duly executed by Seller;

              v.     a "FIRPTA Affidavit" pursuant to Section 1445 (b)(2) of
the Internal Revenue Code, duly executed by Seller;

              vi.    such resolutions, authorizations, bylaws or other
corporate and/or partnership documents or agreements relating to Seller as
shall be required by the Title Company;

              vii.   the certificate certifying as to Seller's representations
and warranties as required by Subparagraph 6(c) above;

              viii.  keys to all locks located in or about any portion of the
Property and all personal property described in the Bills of Sale to the extent
in Seller's possession or reasonable control; and

              ix.    any other customary and/or reasonable closing documents
requested by the Title Company.

       Purchaser may waive compliance on Seller's part under any of the
foregoing items by an instrument in writing.

       d.     At or before the Closing, Purchaser shall deliver to Seller the
following:





9
<PAGE>   10




              i.     the duly executed Assignment of Leases and Assignment of
Intangible Property;

              ii.    such resolutions, authorizations, bylaws or other
corporate and/or partnership documents or agreements relating to Purchaser as
shall be required by Title Company;

              iii.   any other customary and/or reasonable closing documents
requested by the Title Company;

              iv.    in sufficient time to permit an 8:00 a.m. (Dallas time)
Closing, the balance of the Purchase Price in cash or other immediately
available funds, subject to prorations and adjustments as set forth herein.

       e.     Seller and Purchaser shall each deposit such other instruments as
are reasonably required by the escrow holder or otherwise required to close the
escrow and consummate the acquisition of the Property in accordance with the
terms hereof.  Seller and Purchaser hereby designate Title Company as the
"Reporting Person" for the transaction pursuant to Section 6045(e) of the
Internal Revenue Code and the regulations promulgated thereunder and agree to
execute such documentation as is reasonably necessary to effectuate such
designation.

       f.     The following are to be apportioned as of the Closing Date, as
follows:

              i.     RENT.  Rent for the current month under the Leases shall
be apportioned as of the Closing Date, regardless of whether or not such rent
has been paid to Seller.  With respect to any rent arrearages arising under the
Leases, after Closing Purchaser shall pay on or before the 15th day of each
calendar month to Seller any rent actually collected during the preceding month
that is applicable to the period preceding the Closing Date; provided, however,
that all rent collected by Purchaser shall be applied first to all unpaid rent
accruing after the Closing Date, and then to unpaid rent accruing prior to the
Closing Date.  Purchaser shall use reasonable efforts for a period of six (6)
months after Closing to recover rent arrearages, provided that Purchaser shall
not be obligated to sue any Tenant, evict any Tenant or institute any other
legal or quasi-legal proceeding against any Tenant.  Seller shall not be
permitted to take any steps to recover any rent arrearages after Closing,
provided that Seller shall have the right to commence suit against a Tenant to
recover rent arrearages for a period of six (6) months after the Closing and
prosecute such suit to completion and Seller shall have the right to sue a
Tenant at any time after such Tenant's Lease has expired or otherwise
terminates, provided that in no event shall Seller have the right to bring
either an unlawful detainer action or seek recourse to a Tenant's security
deposit transferred to Purchaser.

              ii.    LEASING COSTS; TENANT INDUCEMENTS.  Seller shall pay all
leasing commissions and tenant improvement costs that arise in connection with
any Lease executed on or before the Contract Date.  With respect to any new
Lease or Lease





10


<PAGE>   11



extension or expansion entered into by Seller between the Contract Date and the
Closing Date and approved by Purchaser pursuant to the terms of Paragraph 15(a)
below, in the event that Seller incurs or pays any costs or expenses for
leasing commissions and/or tenant allowances or improvements and/or free rent
(collectively, "New Leasing Costs") in connection with any such new Lease or
such extension or expansion in excess of the gross rental (including base rent,
additional rent and pass-throughs) (collectively, "New Leasing Revenue")
received by Seller with respect to such new Lease or such extension, Seller
shall be entitled to a credit at the Closing for the difference between the New
Leasing Costs and the New Leasing Revenue.  With respect to any free rent
applicable to the period after the Closing that arises under any new Lease or
Lease extension or expansion entered into by Seller between the Contract Date
and the Closing Date and approved by Purchaser pursuant to the terms of
Paragraph 15(a) below, such free rent shall be prorated between Seller and
Purchaser based on the number of months (or fractional months) in such new
Lease or such extension or expansion that are prior to the Closing Date and the
number of such months (or fractional months) that are after the Closing Date.

              iii.   SECURITY DEPOSITS; PREPAID RENT.  Purchaser shall be
entitled to a credit against the Purchase Price for the total sum of all
security deposits (and interest earned thereon) that are required to be
returned to the Tenants under the terms of the respective Leases.
Additionally, Purchaser shall be entitled to a credit against the Purchase
Price for the total sum of all free rent, operating expense abatements, or
other unexpired concessions under any Leases executed prior to the Contract
Date to the extent they apply to any period after the Closing.

              iv.    OTHER TENANT CHARGES.  For all items subject to proration
for which the landlord receives reimbursement from the tenants as common area
maintenance charges ("CAM Charges"), it is acknowledged that Seller has prepaid
certain CAM Charges and already received reimbursement on account of certain
estimated CAM Charges for the period prior to Closing and Purchaser will
similarly make certain payments and receive reimbursements on account of CAM
Charges for the period after Closing.  Seller shall be responsible for
collection of all estimated CAM Charges, including all delinquent amounts,
payable by the tenants prior to Closing, and Purchaser shall be responsible for
collection of all estimated CAM Charges, including delinquent amounts, payable
by the tenants after Closing.  Consistent with the foregoing sentence,
Purchaser and Seller shall prorate the expense items which are subject to
reimbursement pursuant to the CAM Charges in such a way that Seller shall be
responsible for the payment of all costs and expenses which are intended to be
reimbursed by such CAM Charges for the period prior to Closing and Purchaser
shall be responsible for all such costs and expenses after Closing.  At the end
of the fiscal year





11
<PAGE>   12



applicable to the CAM Charges described in the preceding sentences of this
Section, to the extent that the landlord has received excess CAM Charges and is
obligated to reimburse to the tenants any portion of the excess CAM charges
collected by Seller, Seller shall, within ten (10) days of written demand
therefor, reimburse to Purchaser the portion of such excess CAM Charges which
have been paid to and retained by Seller.  In the event that at the end of the
fiscal year applicable to such CAM Charges, tenants on the Property are
obligated to pay to the landlord any sums on account of an underpayment of CAM
Charges, Purchaser shall pay to Seller immediately upon receipt thereof
Seller's prorata share of such reimbursement by the tenants.  Purchaser shall
deliver to Seller at the same time that such notices are delivered to the
tenants any accounting or reconciliation of the CAM Charges for the fiscal year
in which the Closing occurs.

              v.     UTILITY CHARGES.  Seller shall be responsible for the cost
of all utilities used prior to the Closing Date, except to the extent such
utility charges are billed to and paid by tenants directly.

              vi.    OTHER APPORTIONMENTS; CLOSING COSTS.  Amounts payable
under the Assumed Contracts, annual or periodic permit and/or inspection fees
(calculated on the basis of the period covered), and liability for other
Property operation and maintenance expenses and other recurring costs shall be
apportioned as of the Closing Date.  Seller shall pay all transfer taxes and
sales tax (if any) on the Personal Property.  Seller shall pay the premium for
the Title Policy, provided that Purchaser shall pay the cost of the
Endorsements.  Purchaser acknowledges that if title to the Property and the
"Property" described and defined in the Other Agreements is taken in the name
of the same entity or entities, and unless business reasons (e.g. financing
requirements) dictate otherwise as determined by Purchaser in its good faith
discretion, Purchaser shall obtain one title policy covering both the Property
and the "Property" described and defined in the Other Agreements.  Seller and
Purchaser shall each pay fifty percent (50%) of all escrow and recording and
notary fees.  Seller shall be responsible for all costs incurred in connection
with the prepayment or satisfaction of any loan secured by the Property,
including, without limitation, any prepayment fees, penalties or charges.  All
other costs and charges of the escrow for the sale not otherwise provided for
in this Subparagraph 7(f)(vi) or elsewhere in this Agreement shall be allocated
in accordance with the applicable closing customs for Dallas County, Texas.

              vii.   REAL ESTATE TAXES AND SPECIAL ASSESSMENTS.  General real
estate taxes payable for 1996 and all prior years (including subsequent taxes
and assessments for prior years due to change in land usage or ownership) shall
be paid by Seller.  General real estate taxes payable for 1997 shall be
prorated by Seller and Purchaser as of the Closing Date.  If the amount of
general real estate taxes for 1997 cannot be determined on the Closing Date,
Seller shall deposit with the Title Company, from the Purchase Price, an amount
equal to Seller's proportionate share of the 1997 taxes based upon the most
current estimate of such taxes, assuming for estimating purposes that the
Property shall be fully assessed.  Such deposit shall be held in escrow and all
interest earnings on such deposit shall be paid to Seller.  The Title Company
shall retain such deposit to pay Seller's share of the actual general real
estate taxes payable for 1997, paying any excess over to Seller.  Seller shall
pay any deficiency, when such general real estate taxes are known.

              viii.  PRELIMINARY CLOSING ADJUSTMENT.  Seller and Purchaser
shall jointly prepare a preliminary Closing adjustment on the basis of the
Leases and other sources of income and expenses, and shall deliver such
computation to Title Company not less than 10 days prior to Closing.

              ix.    POST-CLOSING RECONCILIATION.  If any of the aforesaid
prorations cannot be calculated accurately on the Closing Date, then they shall
be calculated as soon after the Closing Date as feasible.  Either party owing
the other party a sum of money based on such subsequent proration(s) shall
promptly pay said sum to the other party, together with interest thereon at the
rate of the lesser of (A) two percent (2%) over the average "prime rate" (as
announced from time to time in the Wall Street Journal) per annum or (B) the
highest legally permitted rate, from the Closing Date to the date of payment if
payment is not made within ten (10) days after delivery of a bill therefor.

       SURVIVAL.  The provisions of this Subparagraph 8(f) shall survive the
Closing.

       l.     No brokerage or similar fee is due or unpaid by Seller with

exercise of, without limitation, any renewal, extension or expansion options
arising under any Lease.

        Except as set forth in this Agreement or in any document executed
pursuant to or in connection with this Agreement, the parties hereto
acknowledge and agree that the sale of the Property to Purchaser is made on an
"AS-IS, WHERE-IS" and "WITH ALL FAULTS" basis, and Seller makes no warranty or
representation, express or implied, as to merchantability, suitability or
fitness for a particular purpose, the state of repair of the Property or the
physical condition thereof.  The parties further agree, however, that this
paragraph does not affect an assumption of any liability by Purchaser and that
this paragraph shall not be construed as to waive any rights of contribution or
indemnity or otherwise affect the liabilities of the parties to each other or
to third parties under any environmental law, including CERCLA.  The provisions
of this paragraph shall survive the Closing and the delivery and recordation of
the Deed.

       The representations and warranties set forth in this Paragraph 9 shall

<PAGE>   16



       b.     Purchaser has neither filed nor been subject to the filing of a
petition under the Federal Bankruptcy Law or any federal or state insolvency
laws or laws for the composition of indebtedness or for the reorganization of
debtors that remains pending.

       c.     Purchaser is experienced in evaluating and investing in
properties similar in type and character to the Property.

       The representations and warranties set forth in this Paragraph 10 shall
survive the Closing for the period set forth in Paragraph 17(e) below.

11.    Other Agreements.

       a.     Notwithstanding anything to the contrary in this Agreement, but
subject to the provisions of Paragraph 11(b) below, it shall be a condition
precedent to both Purchaser's obligation to purchase the Property hereunder and
to Seller's obligation to sell the Property hereunder that the "Closing" under
and as defined in each of those three other Purchase Agreements dated as of
even date herewith and identified on Schedule 3 attached hereto (the "Other
Agreements") occurs concurrently with the Closing hereunder.  The parties
acknowledge and agree that a default by Seller under this Agreement shall be
deemed a default of each of the "Sellers" under each of the Other Agreements
and that a default by a "Seller" under any of the Other Agreements shall be
deemed a default by Seller hereunder.  The parties further acknowledge and
agree that a default by Purchaser under this Agreement shall be deemed a
default of each of the "Purchasers" under each of the Other Agreements and that
a default by a "Purchaser" under any of the Other Agreements shall be deemed a
default by Purchaser hereunder.

              b.     Notwithstanding anything to the contrary provided in
Paragraph 11(a) above or elsewhere in this Agreement or any Other Agreement, in
the event that (i) Purchaser discovers during the Due Diligence Period that a
Constituent Parcel (as defined below) is in material violation of any
Environmental Law (but only if Seller fails to cure such violation prior to the
Closing Date, as such may be extended pursuant to this Paragraph 11(b), and
Seller is unwilling to give Purchaser a credit at Closing in such amount as the
parties agree upon will compensate Purchaser for such matter, it being
acknowledged by the parties hereto that Seller shall not be obligated hereunder
to elect to cure any such violation or offer to give Purchaser such a credit),
(ii) Purchaser discovers during the Due Diligence Period that there is a
material defect in title that adversely affects the marketability or
financability of the Constituent Parcel (but only if Seller fails to remedy
such defect prior to the Closing Date, as such may be extended pursuant to this
Paragraph 11(b), and Seller is unwilling to give Purchaser a credit at Closing
in such amount as the parties agree upon will compensate Purchaser for such
matter, it being acknowledged by the parties hereto that Seller shall not be
obligated hereunder to elect to remedy any such defect or offer to give
Purchaser such a credit), (iii) Purchaser determines during the Due Diligence
Period that the net operating income derived from the Property and the
"Property" described and defined in the Other Agreements differs in





16


<PAGE>   17



any material respect in the aggregate from that set forth in any materials
delivered to Purchaser by Seller or its agents prior to Purchaser's execution
of this Agreement or on the Rent Roll (as defined below) and one-third (1/3) or
more of such discrepancy is attributable to any Constituent Parcel (but only to
the extent Seller is unwilling to give Purchaser a credit at Closing in an
amount equal to such loss of income, capitalized at the same rate as that
reflected by the Purchase Price, it being acknowledged by the parties hereto
that Seller shall not be obligated hereunder to offer to give Purchaser such a
credit), (iv) any of Seller's representations and warranties is not true and
correct in all material respects at Closing with respect to a Constituent
Parcel, (v) Purchaser discovers during the Due Diligence Period that there is a
material defect in the physical condition of a Constituent Parcel as disclosed
in an independent third party structural or physical report obtained by
Purchaser (but only if Seller fails to repair all such physical conditions
prior to the Closing Date, as such may be extended pursuant to this Paragraph
11(b), and Seller is unwilling to give Purchaser a credit at Closing in such
amount as the parties agree upon will compensate Purchaser for such matter, it
being acknowledged by the parties hereto that Seller shall not be obligated
hereunder to elect to repair such conditions or offer to give Purchaser such a
credit), or (vi) Purchaser elects to terminate this Agreement as to a
Constituent Parcel pursuant to Paragraph 12 below, Purchaser shall have the
right to terminate this Agreement as to such affected Constituent Parcels only
(each such Constituent Parcel being referred to herein as a "Removed Parcel"),
in which event this Agreement shall be amended to delete all references to the
Removed Parcel(s), the Purchase Price shall be reduced by the amount allocated
to the Removed Parcel(s) as set forth on Schedule 4 attached hereto, and this
Agreement and the Other Agreements shall otherwise remain in full force and
effect; provided, however, that with respect to the circumstances described in
clauses (i), (ii), (iii) and (v) above, Purchaser's right of termination shall
be conditioned upon Purchaser's informing Seller in writing prior to the end of
the Due Diligence Period that Purchaser will terminate this Agreement as to
such affected Constituent Parcel if such matter is not cured or remedied or
Purchaser is not otherwise compensated, as applicable, prior to the Closing.
Seller shall have the right to extend the Closing Date with respect to any
affected Parcel for up to sixty (60) days to remedy or cure any such
objectionable matter, provided that Seller (i) delivers written notice to
Purchaser within five (5) days after the end of the Due Diligence Period, which
notice shall state that Seller is electing to extend the Closing Date and that
Seller will use all commercially reasonable efforts to cure or remedy such
matter, and (ii) thereafter diligently proceeds to attempt to cure or remedy
such matter.  The sixty (60) day period set forth in the immediately preceding
sentence shall run concurrent with the sixty (60) day period set forth in
Paragraph 6(c) above.

       c.     Notwithstanding anything to the contrary provided in Paragraph
11(a) above or elsewhere in this Agreement or any Other Agreement, in the event
that the Removed Parcel(s) constitute(s) the entire Property, Purchaser shall
have the right to terminate this Agreement in its entirety, but elect to keep
the Other Agreements in full force and effect.

<PAGE>   18




       d.     As used herein, the term "Constituent Parcel" shall mean one of
the projects identified on Schedule 4 attached hereto, together with the Land
and all other portions of the Property properly allocable thereto.

12.    Risk of Loss.

       a.     Purchaser shall be bound to purchase the Property for the full
Purchase Price as required by the terms hereof, without regard to the
occurrence or effect of any damage to the Property or destruction of any
improvements thereon or condemnation of any portion of the Property, provided
that (i) the cost to repair any such damage or destruction to a Constituent
Parcel, or the diminution in the value of the remaining Property as a result of
a partial condemnation, does not exceed $250,000 (and the cost to repair all
such damage or destruction to, or the diminution in value of, the Property and
the "Property" described and defined in the Other Agreements, in the aggregate,
does not exceed $1,000,000), and (ii) upon the Closing, there shall be a credit
against the Purchase Price due hereunder equal to the amount of any insurance
proceeds or condemnation awards collected by Seller as a result of any such
damage or destruction or condemnation, less any sums reasonably expended by
Seller toward the restoration or repair of the affected Property, and, if the
proceeds or awards have not been collected as of the Closing, then such
proceeds or awards shall be assigned to Purchaser.

       b.     If the amount of the damage or destruction or condemnation as
specified in Paragraph 12(a) above exceeds $250,000 with respect to any
Constituent Parcel, then Purchaser may, at its option to be exercised within
twenty (20) days of Seller's written notice of the occurrence of the damage or
destruction or the commencement of condemnation proceedings, either terminate
this Agreement in its entirety or solely with respect to such Constituent
Parcel or consummate the purchase for the full Purchase Price as required by
the terms hereof.  Similarly, if the amount of the damage or destruction or
condemnation as specified in Paragraph 12(a) above exceeds $1,000,000 with
respect to the Property and the "Property" described and defined in the Other
Agreements, in the aggregate, then Purchaser may, at its option to be exercised
within twenty (20) days of Seller's written notice of the occurrence of the
damage or destruction or the commencement of condemnation proceedings, either
terminate this Agreement in its entirety or consummate the purchase for the
full Purchase Price as required by the terms hereof.  If Purchaser elects to
terminate this Agreement in its entirety or fails to give Seller written notice
within such 20-day period that Purchaser will proceed with the purchase, then
the Deposit shall be immediately returned to Purchaser and neither party shall
have any further rights or obligations hereunder, except to the extent
expressly otherwise set forth herein.  If Purchaser elects to terminate this
Agreement solely with respect to such affected Constituent Parcel, the
provisions of Paragraph 11(b) above shall control.  If Purchaser elects to
proceed with the purchase as to the entire Property, then upon the Closing,
there shall be a credit against the Purchase Price due hereunder equal to the
amount of any insurance proceeds or condemnation awards collected by Seller as
a result of any such damage or destruction or condemnation, less any sums
reasonably





18


<PAGE>   19



expended by Seller toward the restoration or repair of the affected Property,
and, if the proceeds or awards have not been collected as of the Closing, then
such proceeds or awards shall be assigned to Purchaser.

       c.     In the event that Purchaser is required to or elects to purchase
the entire Property following any damage or destruction or condemnation of the
Property pursuant to Paragraph 12(a) or (b) above, Seller shall also provide
Purchaser with a credit against the Purchase Price in an amount equal to any
deductible or uninsured amount; provided, however, in no event shall Seller be
required to provide Purchaser with a credit pursuant to this Paragraph 12(c) in
an amount that exceeds $250,000 with respect to any Constituent Parcel or that
exceeds $1,000,000 with respect to the Property and the "Property" described
and defined in the Other Agreements, in the aggregate.  If it is determined
that the deductible or uninsured amount is greater than $250,000 (or
$1,000,000, as applicable), Seller shall notify Purchaser in writing as soon as
reasonably possible following such determination whether or nor Seller is
willing to provide Purchaser with a credit against the Purchase Price in the
full amount of such deductible or uninsured amount.  In the event that Seller
is unwilling to provide Purchaser with a credit in such full amount, Purchaser
shall have the right to terminate this Agreement by delivering written notice
to Seller within twenty (20) days after Purchaser's receipt of such notice from
Seller.  If Purchaser elects to terminate this Agreement or fails to give
Seller written notice within such twenty (20) day period that Purchaser will
proceed with the purchase, the Deposit shall be immediately returned to
Purchaser and neither party shall have any further obligations hereunder,
except to the extent expressly otherwise set forth herein.

13.    Possession.

       Possession of the Property shall be delivered to Purchaser on the
Closing Date subject only to the rights of Tenants under the Leases, provided,
however, that prior to the Closing Date Seller shall afford authorized
representatives of Purchaser (as well as any actual or prospective lender to
Purchaser) reasonable access to the Property, upon 24 hours notice, for
purposes of satisfying Purchaser (and such lender) with respect to the
representations, warranties and covenants of Seller contained herein and with
respect to satisfaction of any Diligence Period Condition or any Condition
Precedent (including, without limitation, the Condition Precedent set forth in
Paragraph 6(d) above) and for the purpose of conducting Tenant interviews,
provided that prior to entering the Property Purchaser shall (i) obtain
comprehensive general liability insurance in an amount not less than $1,000,000
naming Seller as an additional insured and (ii) provide a copy of such policy
or a certificate evidencing such coverage to Seller.  Purchaser hereby agrees
to indemnify and hold Seller harmless from any damage or injury to persons or
property caused by Purchaser or its authorized representatives during their
entry and investigations prior to the Closing, provided the foregoing shall not
require Purchaser to indemnify Seller or any other person with respect to any
conditions that are discovered by Purchaser as opposed to being first caused by
Purchaser.  If this Agreement is terminated, Purchaser shall repair the damage
caused by Purchaser's entry and investigations, provided the





19
<PAGE>   20



foregoing shall not require Purchaser to repair or remediate any conditions
that are discovered by Purchaser as opposed to being first caused by Purchaser.
The foregoing indemnity shall survive the termination of this Agreement or the
Closing, as applicable.

14.    Maintenance of the Property; Miscellaneous Covenants.

       Between the Contract Date and the Closing, Seller shall perform all of
the landlord's obligations under the Leases and shall otherwise operate and
maintain the Property in the same manner as before the making of this
Agreement, as if Seller were retaining the Property.  Seller shall promptly
notify Purchaser of any condemnation, environmental, zoning or other land-use
regulation proceedings of which Seller becomes aware, as well as any notices of
violations of any Laws relating to the Property of which Seller becomes aware
and any litigation of which Seller becomes aware that arises out of the
ownership of the Property or that might detrimentally affect the value or the
use or operation of the Property or the ability of Seller to perform its
obligations hereunder.  Following the Contract Date, Seller shall continue to
prepare Operating Statements (as defined in Exhibit G hereto) for the Property
as to all time periods subsequent to the dates of the Operating Statements
delivered to Purchaser as part of the Delivery Items and prior to the Closing
Date, which Operating Statements shall be delivered to Purchaser within a
reasonable period of time following the end of the period with respect to which
such Operating Statements are prepared, even if prepared after Closing.
Through the Closing Date, Seller shall maintain or cause to be maintained, at
Seller's sole cost and expense, all policies of insurance currently in effect
with respect to the Property (or comparable replacements thereof).

15.    Purchaser's Consent to New Contracts Affecting the Property; Termination
       of Existing Contracts.

       a.     Seller shall not, after the Contract Date, enter into any Lease
or contract, or any amendment thereof, or permit any Tenant to enter into any
sublease, assignment or agreement pertaining to the Property, or waive any
rights of Seller under any contract or Lease, without in each case obtaining
Purchaser's prior written consent thereto, which consent in the case of any
Lease shall include approval of the financial condition of the proposed tenant,
the configuration of the space to be leased, and the terms of such Lease
(including, without limitation, the rent and any concessions provided under
such proposed Lease), and which consent shall not be unreasonably withheld by
Purchaser.  Seller shall be entitled, without the consent of Purchaser, to
enter into, amend or otherwise deal with service contracts and similar
agreements that are not Assumed Contracts in the ordinary course of business
that are terminable on not more than thirty (30) days' prior notice and which
shall not be binding on Purchaser after the Closing Date.  Seller shall deliver
to Purchaser, together with any request for approval of a new Lease, a copy of
the proposed Lease, a description of the proposed Tenant and its proposed use
of the premises and whatever financial information on the proposed Tenant
Seller has received, as well as any additional information reasonably requested
by





20


<PAGE>   21



Purchaser (including, without limitation, if applicable, an environmental
questionnaire).  Notwithstanding anything to the contrary provided in this
Subparagraph 15(a), if Purchaser fails to respond in writing with respect to
any such new Lease or other action requiring Purchaser's consent under this
Subparagraph 15(a) within five (5) business days after Purchaser's receipt of
such request and information, Purchaser shall be deemed to have approved such
new Lease or other action.

       b.     Seller shall terminate prior to the Closing, at no cost or
expense to Purchaser, any and all management agreements, service contracts or
similar agreements affecting the Property that are not Assumed Contracts.

       c.     Seller shall not, after the Contract Date, create any new
encumbrance or lien affecting the Property other than liens and encumbrances
(i) that are reasonably capable of being discharged prior to the Closing and
(ii) that in fact will be and are discharged prior to the Closing.

16.    Cooperation with Purchaser.

       Seller shall cooperate and do all acts as may be reasonably required or
requested by Purchaser with regard to the fulfillment of any Condition
Precedent including execution of any documents, applications or permits
reasonably requested by Purchaser and, to the extent requested by Purchaser,
agrees to cooperate with Purchaser's efforts to obtain subordination, non-
disturbance and attornment agreements from the Tenants.  Seller hereby
authorizes Purchaser and its agents to make all inquiries with and applications
to any third party, including any governmental authority, as Purchaser may
reasonably require to complete its due diligence.

17.    Miscellaneous.

       a.     NOTICES.  Any notice, consent or approval required or permitted
to be given under this Agreement shall be in writing and shall be deemed to
have been given upon (i) hand delivery, (ii) one (1) business day after being
deposited with Federal Express or another reliable overnight courier service,
with receipt acknowledgment requested, (iii) upon receipt if transmitted by
facsimile telecopy, or (iv) upon receipt or refused delivery deposited in the
United States mail, registered or certified mail, postage prepaid, return
receipt required, and addressed as follows:

       b.     BROKERS AND FINDERS.  Neither party has had any contact or
dealings regarding the Property, or any communication in connection with the

person who can claim a right to a commission or finder's fee in connection with
the sale contemplated herein, except for Cushman & Wakefield of Texas, Inc.
("Broker"), whose commission shall be paid by Seller pursuant to the terms of a

       c.     SUCCESSORS AND ASSIGNS.  This Agreement shall be binding upon,
and inure to the benefit of, the parties hereto and their respective
successors, heirs, administrators and assigns.  Notwithstanding the foregoing,
Purchaser shall not have the right, without the prior written approval of
Seller, to assign this Agreement in whole or in part, provided that Purchaser

obtaining Seller's consent) in whole or in part to (i) one or more entities in
which Marc R. Brutten, Jay H. Shidler and/or James C. Reynolds, directly or
indirectly, has an ownership interest, and/or (ii) an entity controlled or
managed by, or otherwise affiliated with, Angelo Gordon & Co., provided that
such assignee(s) shall assume all of the obligations of Purchaser hereunder and
the foregoing shall not act as a release of the party originally designated as
Purchaser hereunder.  To the extent that any indemnity set forth in this
Agreement is made for the benefit of Purchaser or Seller, the term "Purchaser"
or "Seller", as applicable, as it pertains to an indemnified party only, shall

include the managers, members, investors, affiliates, lenders, officers,
directors, shareholders, partners, trustees, beneficiaries, agents and
employees of such party and their respective heirs, representatives, successors
and assigns.

Purchaser.

       e.     CONTINUATION AND SURVIVAL OF REPRESENTATIONS AND WARRANTIES, ETC.
All representations and warranties by the respective parties contained herein
or made in writing pursuant to this Agreement are intended to and shall remain
true and correct as of the time of Closing, shall be deemed to be material,
and, together with all conditions, covenants and indemnities made by the
respective parties contained herein or made in writing pursuant to this
Agreement, shall survive the execution and delivery of this Agreement and the
Closing for a period of 12 months, or, to the extent the context requires,
beyond any termination of this Agreement.  In the event that a claim is not
made with respect to a breach of a representation, warranty or covenant set
forth herein within such 12 month period, such claim shall be deemed waived.

       f.     GOVERNING LAW.  This Agreement shall be governed by and construed
in accordance with the laws of the State of Texas.

       g.     MERGER OF PRIOR AGREEMENTS.  This Agreement and the exhibits and
schedules hereto constitute the entire agreement between the parties and
supersede all prior agreements and understandings between the parties relating
to the subject matter hereof.

       h.     ENFORCEMENT.  If either party hereto fails to perform any of its
obligations under this Agreement or if a dispute arises between the parties
hereto concerning the meaning or interpretation of any provision of this
Agreement, then the defaulting party or the party not prevailing in such
dispute shall pay any and all costs and expenses incurred by the other party on
account of such default and/or in enforcing or establishing its rights
hereunder, including, without limitation, court costs and attorneys' fees and
disbursements.  Any such attorneys' fees and other expenses incurred by either
party in enforcing a judgment in its favor under this Agreement shall be
recoverable separately from and in addition to any other amount included in
such judgment, and such attorneys' fees obligation is intended to be severable
from the other provisions of this Agreement and to survive and not be merged
into any such judgment.

       i.     TIME OF THE ESSENCE.  Time is of the essence of this Agreement.

       j.     SEVERABILITY.  If any provision of this Agreement, or the
application thereof to any person, place, or circumstance, shall be held by a
court of competent jurisdiction to be invalid, unenforceable or void, the
remainder of this Agreement and such provisions as applied to other persons,
places and circumstances shall remain in full force and effect.

       k.     MARKETING.  During the term of this Agreement, Seller shall not

Property, engage in any discussions or negotiations with any third party with
respect to the sale or other disposition of the Property, or enter into any
contracts or agreements (whether binding or not) regarding any disposition of
the Property.

       l.     CONFIDENTIALITY.  Each party agrees to maintain in confidence,
and not to disclose to any third party, the information contained in this
Agreement or pertaining to the sale contemplated hereby and the information and
data furnished or made available by Seller to Purchaser, its agents and
representatives in connection with Purchaser's investigation of the Property
and the transactions contemplated by the Agreement; provided, however, that
each party, its agents and representatives may disclose such information and
data (a) to such party's accountants, attorneys, prospective lenders,
accountants, partners, consultants and other advisors in connection with the
transactions contemplated by this Agreement (collectively "Representatives") to
the extent that such Representatives reasonably need to know (in Purchaser's or
Seller's reasonable discretion) such information and data in order to assist,
and perform services on behalf of, Purchaser or Seller; (b) to the extent
required by any applicable statute, law, regulation, governmental authority or
court order; and (c) in connection with any litigation that may arise between
the parties in connection with the transactions contemplated by this Agreement.
In the event of any conflict between the terms of this Section 17(l) and the
terms of the Confidentiality Agreement referenced in Section 17(g) above, the
terms of said Confidentiality Agreement shall control.  Each party shall
consult with the other party prior to making any press release or other
disclosure intended for general circulation regarding the transactions
contemplated hereunder.  In no event shall any such disclosure or press release
contain the purchase price.

       m.     SECTION 1031 EXCHANGE.  It is presently contemplated that
Purchaser and Seller may each desire to effectuate a tax-deferred exchange
(also known as a "1031" exchange) (an "Exchange") in connection with the
purchase and sale of the Property.  Purchaser and Seller hereby agree to
cooperate with each other in connection with one or more such Exchanges,
provided that:

              i.     All documents executed by a party in connection with the
Exchange shall be subject to the prior reasonable approval of that party and
shall recognize that that party is acting solely as an accommodating party to
such Exchange, shall have no liability with respect thereto, and is making no
representation or warranty that the transactions qualify as a tax-free exchange
under Section 1031 of the Internal Revenue Code or any applicable state or
local laws and shall have no liability whatsoever if any such transactions
fails to so qualify.

              ii.    Such Exchange shall not result in Purchaser or Seller
incurring any additional costs or liabilities.

              iii.   In no event shall Purchaser or Seller be obligated to
acquire any property or otherwise be obligated to take title, or appear in the
records of title, to any property in connection with such Exchange.

              iv.    In no event shall Purchaser's or Seller's consummation of
such Exchange constitute a condition precedent to that party's obligations
under this Agreement, and Purchaser's or Seller's failure or inability to
consummate such Exchange for any reason or for no reason at all shall not be
deemed to excuse or release that party from its obligations under this
Agreement.

       n.     POST-CLOSING COOPERATION.  If it becomes reasonably necessary to
do so in order to comply with applicable securities laws or the rules or
regulations of the Securities and Exchange Commission, for a period of four (4)
years after the Closing Date, Purchaser and its agents shall have the right, at
Purchaser's sole cost and expense, to inspect and obtain copies of Seller's
books and records supporting the operation of the Property for the period of
three (3) full calendar years preceding the calendar year which includes the
Closing Date.  Purchaser shall give reasonable prior written notice to Seller
when Purchaser wishes to exercise its right to inspect such books and records.
Such inspection shall take place at the office of Seller during normal business
hours on a date and at a time reasonably convenient to Seller and Purchaser.
The provisions of this Paragraph 17(n) shall survive the Closing.

o.     RETURN OF DOCUMENTS.  In the event that this Agreement terminates,
Purchaser shall return to Seller all due diligence materials and all copies
thereof delivered by Seller to Purchaser hereunder and, subject to any
restrictions on transferability set forth therein, shall deliver to Seller
copies of all reports generated by Purchaser's contractors, engineers and other
third party professional (non-legal) consultants, all of which reports shall be
delivered by Purchaser without any representation or warranty as to the
contents thereof.

                     SECOND AMENDMENT TO PURCHASE AGREEMENT

       THIS SECOND AMENDMENT TO PURCHASE AGREEMENT (this "Second Amendment"),
is made as of July 31, 1997, by and between SHIDLER WEST INVESTMENT
CORPORATION, a Delaware corporation ("Purchaser"), and MERIT INDUSTRIAL

defined herein, shall have the meaning ascribed to it in the Purchase
Agreement.

       B.     Seller and Purchaser desire to amend the Purchase Agreement as
set forth in this Second Amendment.

       NOW, THEREFORE, the parties agree as follow:

       1.     Purchase Price.  The first sentence of Paragraph 2(a) of the

                               PURCHASE AGREEMENT

   THIS AGREEMENT is made and entered into as of this 2nd day of July, 1997, by
and between SHIDLER WEST INVESTMENT CORPORATION, a Delaware corporation
("Purchaser"), and MERIT 1995 INDUSTRIAL PORTFOLIO LIMITED PARTNERSHIP, a Texas
limited partnership (Seller").

   IN CONSIDERATION of the respective agreements hereinafter set forth, Seller
and Purchaser hereby agree as follows:

1.  Purchase and Sale.

    Seller agrees to sell and convey to Purchaser, and Purchaser agrees to
purchase from Seller, on the terms and conditions set forth in this Agreement,
the Property.  As used herein, the term the "Property" shall mean,
collectively: (a) the parcels of land described in Exhibit A attached hereto
(collectively, the "Land"), together with all rights, easements and interests
appurtenant thereto including, but not limited to, any streets or other public
ways adjacent to the Land and any development rights, water or mineral rights
owned by, or leased to, Seller; (b) all improvements located on the Land,
including, but not limited to, those certain ten (10) buildings identified on
Schedule 1 attached hereto and all other structures, systems, and utilities
associated with, and utilized by Seller in the ownership and operation of such
building(s) (all such improvements, together with such building(s), being
referred to herein as the "Improvements"), but excluding improvements, if any,
owned by tenants of such building(s); (c) all personal property owned by
Seller, located on or in the Land or Improvements, or used in connection with
the operation and maintenance of the Property (the "Personal Property"),
including, without limitation, all personal property listed on Exhibit B
attached hereto; (d) all building materials, supplies, hardware, carpeting and
other inventory maintained in connection with Seller's ownership and operation
of the Property (the "Inventory"); (e) all trademarks, tradenames, and
entitlements and other intangible property used or useful in connection with
the foregoing, including, without limitation, all of Seller's right, title and
interest in any and all warranties and guaranties relating to the Property, but
excluding all rights to use the name "Merit" (the "Intangible Personal
Property"); and (f) Seller's interest in all leases and other agreements to
occupy all or any portion of the Property that are in effect on the Contract
Date (defined below) or into which Seller enters prior to Closing (defined
below), but pursuant to the terms of this Agreement (as such may have been
amended, modified or supplemented, the "Leases").

2.  Purchase Price; Independent Contract Consideration.

        a.       The purchase price of the Property shall be Fifteen Million
Fifty-Five Thousand Dollars ($15,055,000.00) (the "Purchase Price").  The
Purchase Price shall be paid to Seller at Closing, plus or minus prorations and
other adjustments hereunder, in immediately available funds.

<PAGE>   2
        b.       The Purchase Price shall be paid as follows:

                 i.         Upon mutual execution of this Agreement, Purchaser 
shall deliver to Commonwealth Land Title Company of Dallas ("Title Company") a
deposit in the amount of One Hundred Fifty Thousand Dollars ($150,000.00) (the
"Initial Deposit; and, together with the Extension Deposit (as defined below),
if applicable, the "Deposit").  The Deposit shall be held in an
interest-bearing account and interest accruing thereon shall be held for the
account of Purchaser.  In the event the sale of the Property as contemplated
hereunder is consummated, the Deposit plus interest accrued thereon shall be
delivered to Seller at the Closing and credited against the Purchase Price.

                 ii.        Prior to or contemporaneous with the execution 
hereof by Purchaser and Seller, Purchaser has paid to Seller One Hundred
Dollars ($100.00) (the "Independent Contract Consideration"), which amount
Seller and Purchaser bargained for and agreed to as consideration for Seller's
execution and delivery of this Agreement.  The Independent Contract
Consideration is non-refundable and in addition to any other payment or deposit
required by this Agreement, and Seller shall retain the Independent Contract
Consideration notwithstanding any other provision of this Agreement to the
contrary; provided, however, that if the Closing shall occur hereunder, then
the Independent Contract Consideration shall be applied to the Purchase Price.

                 iii.       The balance of the Purchase Price shall be paid to 
Seller at the closing of the purchase and sale contemplated hereunder (the
"Closing").

3.  Title to the Property.

        a.       At the Closing, Seller shall convey to Purchaser indefeasible
and insurable fee simple title to the Land and the Improvements, by one or more
duly executed and acknowledged special warranty deeds in the form attached
hereto as Exhibit C (collectively, the "Deed").  Evidence of delivery of
indefeasible and insurable fee simple title shall be the issuance by Title
Company to Purchaser of a Texas Owner's Policy of Title Insurance (Form T-1) in
the amount of the Purchase Price (the "Title Policy"), insuring fee simple
title to the Land and the Improvements in Purchaser, subject only to such
exceptions as Purchaser shall approve pursuant to Subparagraph 5(a) below (the
"Permitted Exceptions").  The Title Policy shall contain such special
endorsements as Purchaser may reasonably require, including, without
limitation, the amendment of the survey exception to read "shortages in area"
only (the "Endorsements").  The Title Company shall also provide for
reinsurance with direct access with such companies and in such amounts as
Purchaser shall reasonably request.

        b.       At the Closing, Seller shall transfer title to the Personal
Property and the Inventory by a bill of sale in the form attached hereto as
Exhibit D (the "Bill of Sale"), such title to be free of any liens,
encumbrances or interests, other than the Permitted Exceptions.

<PAGE>   3
        c.       At the Closing, Seller shall transfer title to the Intangible
Personal Property by an assignment of service contracts, warranties and
guaranties and other intangible property in the form attached hereto as Exhibit
E (the "Assignment of Intangible Property") and shall transfer title to the
Leases by an assignment of leases in the form attached hereto as Exhibit F (the
"Assignment of Leases"), such title to be free of any liens, encumbrances or
interests, other than the Permitted Exceptions.

4.  Due Diligence and Time for Satisfaction of Conditions.

    Purchaser shall have the right to commence due diligence with respect to the
Property following the date on which this Agreement is fully executed by the
parties hereto (the "Contract Date") and the due diligence period ("Due
Diligence Period") shall expire on July 30, 1997, provided, however, in the
event that Seller fails to deliver to Purchaser any of the items identified on
Exhibit G attached hereto and identified with an asterisk (the "Delivery
Items") on or before the date that is five (5) days after the Contract Date,
the Due Diligence Period shall be extended with respect to such undelivered
Delivery Item only by one day for each day beyond such fifth (5th) day until
such Delivery Item is delivered to Purchaser.  In addition to the foregoing,
Seller shall, upon 24 hours notice, make available to Purchaser and its
employees, representatives, counsel and consultants access to all of its books,
records and files relating to the Property in Seller's possession or reasonable
control, including, without limitation, all of the items set form on said
Exhibit G other than the Delivery Items, and Seller agrees, to the extent
reasonably feasible, to allow Purchaser to make copies at Seller's office or
the property management office of such items as Purchaser reasonably requests.
As used in this Agreement, the term "reasonable control" mean those items in
the possession of Seller's agents or independent contractors under direct
contract with Seller or its affiliates, and the term "affiliate" means any
entity or person controlled by, controlling or under common control with a
named person or entity.

5.  Diligence Period Conditions.

    The following conditions are precedent to Purchaser's obligation to purchase
the Property and to deliver the Purchase Price (the "Diligence Period
Conditions"):

        a.       Purchaser's review and approval of title to the Property, as
follows.  Seller shall deliver to Purchaser at Seller's sole cost and expense,
within five (5) days after the Contract Date, the following:

                 i.         one or more current standard coverage preliminary 
title reports on the Land, issued by Title Company, accompanied by copies of
all documents referred to in the reports (the "Preliminary Reports").  In the
event the Title Company issues any supplements to the Preliminary Reports
during the term of this Agreement, Purchaser shall have five (5) business days
following delivery of any such supplemental report to approve or disapprove in
writing of any exception contained therein and not disclosed in the Preliminary
Reports, or any prior supplement thereto;





3
<PAGE>   4
                 ii.        copies of all existing and proposed easements, 
covenants, restrictions, agreements or other documents which affect title to
the Property and which are not disclosed by the Preliminary Reports;

                 iii.       all surveys of the Land and Improvements in Seller's
possession or reasonable control; and

                 iv.        copies of the most recent property tax bills for the
Property.

   Purchaser shall advise Seller, at least ten (10) days prior to the end of
the Due Diligence Period, what exceptions to title, if any, will be accepted by
Purchaser.  Seller shall have five (5) days after receipt of Purchaser's
objections to give Purchaser:  (i) notice that Seller shall use all reasonable
efforts to remove all disapproved exceptions from title on or before the
Closing Date; or (ii) notice that Seller elects not to cause such exceptions to
be removed.  If Seller gives Purchaser notice under clause (ii), Purchaser
shall have five (5) days to elect to proceed with the purchase or terminate
this Agreement.  If Purchaser shall fail to give Seller notice of its election
within said five (5) days, Purchaser shall be deemed to have elected to
terminate this Agreement.  If Seller gives notice under clause (i) above and
fails to remove all such disapproved exceptions prior to the Closing Date
despite using its reasonable efforts and Purchaser is unwilling to accept title
subject to such exception in its sole and absolute discretion, Purchaser shall
have the right to terminate this Agreement.  Notwithstanding anything to the
contrary provided herein, Seller shall be obligated to remove or endorse over
to the reasonable satisfaction of Purchaser prior to Closing all monetary liens
encumbering the Property (or any portion thereof) other than the lien of any
property taxes, not yet due or payable.

        b.       Purchaser's review and approval of the matters described in
Paragraph 4 above and each component thereof as Purchaser shall desire in its
sole and absolute discretion.  Such review shall include an examination for the
presence or absence of Hazardous Material (as defined in Subparagraph 8(j)
below).  Notwithstanding anything to the contrary contained herein, Purchaser
shall not engage in or otherwise conduct any additional environmental studies
or environmental testing or sampling of any kind with respect to the Property
or with respect to the soils or ground water, or other studies which would
require test boring or which testing would otherwise damage or disturb any
portion of the Property, without obtaining Seller's prior written consent
thereto, which consent shall not be unreasonably withheld, delayed or
conditioned.

        c.       Purchaser's review and approval, within the Due Diligence
Period, of a schedule (the "Schedule of Agreements") setting forth an exclusive
list of all of the service contracts and similar agreements affecting the
Property.  Prior to the end of the Due Diligence Period, Purchaser shall
deliver to Seller a list setting forth those service contracts and similar
agreements that shall be assigned to, and assumed by, Purchaser at the Closing
(the "Assumed Contracts").  Purchaser shall have the right, in its sole
discretion, to require the termination of any service contract or similar
agreement that is





4


<PAGE>   5
not an Assumed Contract effective as of the Closing, provided that either (i)
such contract or agreement is terminable by Seller without the payment of any
fee or penalty and Purchaser provides to Seller adequate notice that Purchaser
shall require the termination of such contract or agreement or (ii) the service
provider is an affiliate of Seller or Seller's general partner.

           Prior to the end of the Due Diligence Period, Purchaser shall
deliver written notice (the "Approval Notice") to Seller informing Seller
whether or not Purchaser has approved or waived all of the Diligence Period
Conditions.  Notwithstanding anything in this Agreement to the contrary,
Purchaser shall have the right to terminate this Agreement at any time prior to
the end of the Due Diligence Period in its sole and absolute discretion and for
any or for no reason whatsoever.  If, by the end of the Due Diligence Period,
Purchaser shall not have delivered the Approval Notice to Seller approving or
waiving all of the Diligence Period Conditions, then this Agreement shall
automatically terminate, the Deposit shall be returned to Purchaser and the
parties shall be released from all obligations hereunder.

6.  Conditions to Closing.

    The following conditions are precedent to Purchaser's obligation to acquire
the Property and to deliver the Purchase Price (the "Conditions Precedent"):

        a.       This Agreement shall not have terminated pursuant to any other
provision hereof, including, without limitation, Paragraph 5 above.

        b.       Seller's obtaining and delivering to Purchaser tenant estoppel
certificates from tenants ("Tenants") occupying all of the rentable area of the
leased premises in the Property that is leased to Tenants, which certificates
shall be in the form of Exhibit I attached hereto (subject only to such changes
and qualifications, including, without limitation, statements alleging defaults
or other matters, as are acceptable to Purchaser in its reasonable discretion)
and shall reflect the terms of the respective Leases, and which certificates
shall be dated (or recertified) no earlier than forty-five (45) days prior to
the Closing Date.  Seller shall deliver to each of the Tenants of the Property,
and shall use its reasonable efforts to obtain from each of the Tenants, a
tenant estoppel certificate in the form attached hereto as Exhibit I, revised
by Seller to reflect the terms of the respective Leases, and modified to
address reasonable, specific concerns arising as a result of Purchaser's review
of the Leases that are conveyed to Seller in writing prior to the expiration of
the Due Diligence Period.  As used in this Section 6(b), reasonable efforts
shall be limited to demand only and Seller shall not be obligated to institute
legal action to require delivery of such estoppel certificates.
Notwithstanding the foregoing, to the extent that Seller has not obtained
satisfactory estoppel certificates from all of the Tenants despite its using
reasonable best efforts, but Seller has obtained satisfactory estoppel
certificates from all of the Major Tenants and from Tenants (including Major
Tenants) occupying ninety percent (90%) or more of the rentable area of the
leased premises in the Property that is leased to Tenants, then Seller shall
deliver to Purchaser a





5
<PAGE>   6
master landlord estoppel dated as of the Closing Date with respect to all
leased space in the Premises for which a satisfactory tenant estoppel
certificate is not delivered by Seller, which master estoppel certificate shall
be in form and substance (based substantially on Exhibit I hereto) reasonably
satisfactory to Purchaser, and the Condition Precedent set forth in this
Paragraph 6(b) shall be deemed satisfied.  The representations and warranties
set forth in Seller's master estoppel certificate shall survive the Closing as
to each such space until the scheduled expiration date of the current term of
the lease for such space.  In the event Seller shall deliver one or more
estoppel certificates, Seller shall have the right, after the Closing, to
continue to obtain estoppel certificates with respect to such leases.  In the
event Seller is able to obtain an estoppel certificate from a tenant for which
Seller delivered a replacement estoppel certificate, then the obligations of
the Seller under the replacement estoppel certificate shall terminate and be of
no further force or effect as of the date of delivery of the estoppel
certificate from the tenant.  As used herein, the term "Major Tenant" shall
mean a Tenant occupying 10,000 rentable square feet or more of leased space in
the Premises.

        c.       All of Seller's representations and warranties contained in or
made pursuant to this Agreement shall have been true and correct when made and
shall be true and correct as of the Closing Date.  At the Closing Seller shall
deliver to Purchaser a certificate certifying that each of Seller's
representations and warranties contained in Paragraph 8 below are true and
correct as of the Closing Date.  In the event that Seller advises Purchaser
prior to the Closing that any of Seller's representations or warranties set
forth herein is not true and correct as a result of an event occurring after
the Contract Date that is beyond the control of Seller or Seller's employees,
partners, agents or contractors, then Purchaser's sole remedy shall be to
cancel and terminate this Agreement and receive the return of the Deposit or to
waive the condition precedent set forth in this Paragraph 6(c) with respect to
such representation or warranty and, in the event the Closing occurs, Purchaser
shall not be entitled to any reduction in the Purchase Price or recover damages
from Seller with respect to such representation or warranty.  Notwithstanding
anything to the contrary set forth above, in the event that Purchaser advises
Seller prior to the Closing that any of Seller's representations or warranties
set forth herein is not true and correct, Seller shall have the right to elect
to cure such untrue or incorrect representation or warranty prior to the
Closing, and in the event that Seller cures all such untrue or incorrect
representations and warranties prior to the Closing, the Condition Precedent
set forth in this Paragraph 6(c) shall be deemed satisfied.  Seller shall have
the right to extend the Closing Date with respect to any affected Constituent
Parcel Constituent Parcel (as defined below) for up to sixty (60) days to cure
any such untrue or incorrect representations or warranties, provided that
Seller (i) delivers written notice to Purchaser within five (5) days after
Seller receives such notification from Purchaser, which notice shall state that
Seller is electing to extend the Closing Date and that Seller will use all
commercially reasonable efforts to cure such untrue or incorrect representation
or warranty, and (ii) thereafter diligently proceeds to attempt to cure all
such untrue or incorrect representations and warranties.  The sixty (60) day
period set





6


<PAGE>   7
forth in the immediately preceding sentence shall run concurrent with the sixty
(60) day period set forth in Paragraph 11(b) below.

        d.       The physical condition of the Property shall be substantially
the same on the day of Closing as on the date of Purchaser's execution of this
Agreement, reasonable wear and tear and loss by casualty excepted (subject to
the provisions of Paragraph 12 below), and, as of the day of Closing, there
shall be no litigation or administrative agency or other governmental
proceeding of any kind whatsoever, pending or threatened, which after Closing
would materially adversely affect the value of the Property or the ability of
Purchaser to operate the Property in the manner in which it is currently being
operated, and no proceedings shall be pending or threatened which could or
would cause the redesignation or other modification of the zoning
classification of, or of any building code requirements applicable to the
Property or any portion thereof.

        e.       Title Company shall be irrevocably and unconditionally
committed to issue to Purchaser the Title Policy as described in Subparagraph
3(a) above.

        The Conditions Precedent are intended solely for the benefit of
Purchaser.  Subject to the provisions of Paragraph 7(b) below, if any of the
Conditions Precedent is not satisfied, Purchaser shall have the right in its
sole discretion either to waive in writing such Condition Precedent without
reduction in the Purchase Price and proceed with the purchase or terminate this
Agreement, in which event the Deposit shall be returned to Purchaser and the
parties shall be released from all obligations hereunder.

        In the event that Purchaser consummates the Closing hereunder,
Purchaser shall be deemed to have waived any and all unsatisfied conditions
precedent.

7.  Remedies.

    a.  In the event the sale of the Property is not consummated because of
the failure of any condition or any other reason except a default under this
Agreement or any of the Other Agreements (as defined below) on the part of
Purchaser, the Deposit plus interest accrued thereon shall immediately be
returned to Purchaser.  If said sale is not consummated because of a default
under this Agreement or under any of the Other Agreements on the part of
Purchaser, the Deposit (but not the interest accrued thereon) shall be paid to
and retained by Seller as liquidated damages.  The parties have agreed that
Seller's actual damages, in the event of a default by Purchaser, would be
extremely difficult or impracticable to determine.  THEREFORE, BY PLACING THEIR
INITIALS BELOW, THE PARTIES ACKNOWLEDGE THAT THE DEPOSIT (AS WELL AS THE
DEPOSIT UNDER EACH OF THE OTHER AGREEMENTS) HAS BEEN AGREED UPON, AFTER
NEGOTIATION, AS THE PARTIES' REASONABLE ESTIMATE OF SELLER'S DAMAGES AND AS
SELLER'S EXCLUSIVE REMEDY AGAINST PURCHASER, AT LAW OR IN EQUITY, IN THE EVENT
OF A DEFAULT UNDER THIS AGREEMENT OR UNDER ANY OF THE OTHER AGREEMENTS ON THE
PART OF PURCHASER.  NOTWITHSTANDING THE FOREGOING PROVISIONS OF THIS





7
<PAGE>   8
PARAGRAPH 7(A), THIS PARAGRAPH 7(A) SHALL NOT LIMIT ANY RECOVERY BY SELLER
PURSUANT TO THE PROVISIONS OF PARAGRAPHS 13, 17(B), 17(H), AND 17(L) BELOW OR
PURSUANT TO THE PROVISIONS OF PARAGRAPHS 13, 17(B), 17(H), AND 17(L) OF ANY OF
THE OTHER AGREEMENTS.

           INITIALS:    Seller _______            Purchaser _______

     b.    In the event the sale of the Property is not consummated because of
a material default under this Agreement on the part of Seller or a material
default under any of the Other Agreements on the part of the "Seller"
thereunder, which default is not cured within three (3) business days after
receipt of written notice from Purchaser, or if a Condition Precedent cannot be
fulfilled because Seller frustrated such fulfillment by some willful act,
Purchaser may elect, as its sole and exclusive remedy hereunder, to either (1)
terminate this Agreement by delivery of notice of termination to Seller,
whereupon (A) the Deposit (as well as the Deposit under each of the Other
Agreements) plus interest accrued thereon shall be immediately returned to
Purchaser, and (B) Seller shall pay to Purchaser any title, escrow, legal and
inspection fees incurred by Purchaser and any other expenses incurred by
Purchaser in connection with the negotiation of this Agreement and the Other
Agreements and Purchaser's pursuit of the transactions contemplated hereunder
and under the Other Agreements and the performance of its due diligence review
of the Property and the "Property" described in the Other Agreements,
including, without limitation, environmental and engineering consultants' fees
and expenses and legal fees, and neither party shall have any further rights or
obligations hereunder, or (2) continue this Agreement pending Purchaser's
action for specific performance.

8.   Closing and Escrow.

     a.    Upon mutual execution of this Agreement, the parties hereto shall
deposit an executed counterpart of this Agreement with Title Company and this
Agreement shall serve as instructions to Title Company for consummation of the
purchase and sale contemplated hereby.  Seller and Purchaser agree to execute
such additional escrow instructions as may be appropriate to enable the escrow
holder to comply with the terms of this Agreement; provided, however, that in
the event of any conflict between the provisions of this Agreement and any
supplementary escrow instructions, the terms of this Agreement shall control.

     b.    The parties shall conduct an escrow Closing pursuant to this
Paragraph 8 on or before September 4, 1997 or on such other date as Purchaser
and Seller may agree in their sole and absolute discretion (the "Closing
Date"), provided, however, that Purchaser shall have the right to extend the
Closing Date on one or more occasions for up to thirty (30) days in the
aggregate so long as Purchaser (i) delivers written notice to Seller not less
than ten (10) business days prior to the then scheduled Closing Date, (ii)
deposits an





8


<PAGE>   9
additional One Hundred Ten Thousand Dollars ($110,000.00) (the "Extension
Deposit") in escrow with Title Company, and (iii) similarly extends the
"Closing Date" under each of the Other Agreements and deposits with Title
Company the "Extension Deposits" thereunder, and Seller shall have the right to
extend the Closing Date with respect to affected Constituent Parcels for up to
sixty (60) days as set forth in Paragraphs 6(c) and 11(b) hereof.  Upon deposit
with Title Company, the Extension Deposit shall be non-refundable, except to
the extent that this Agreement terminates as a result of a Seller default or
the failure of a condition to Closing for the benefit of Purchaser.

     c.    At or before the Closing, Seller shall deliver to Purchaser the
following:

           i.         the duly executed (and where appropriate acknowledged)
Deed, Bill of Sale, Assignment of Intangible Property and Assignment of Leases;

           ii.        duly executed estoppel certificates as required pursuant
to Subparagraph 8(b) above;

           iii.       originals of all Leases, Assumed Contracts, and building
permits, certificates of occupancy and plans and specifications for the
Improvements and all tenant-occupied space included within the Improvements to
the extent in Seller's possession or reasonable control;

           iv.        notices to the Tenants in form satisfactory to Purchaser,
duly executed by Seller;

           v.         a "FIRPTA Affidavit" pursuant to Section 1445 (b)(2) of
the Internal Revenue Code, duly executed by Seller;

           vi.        such resolutions, authorizations, bylaws or other
corporate and/or partnership documents or agreements relating to Seller as
shall be required by the Title Company;

           vii.       the certificate certifying as to Seller's representations
and warranties as required by Subparagraph 6(c) above;

           viii.      keys to all locks located in or about any portion of the
Property and all personal property described in the Bills of Sale to the extent
in Seller's possession or reasonable control; and

           ix.        any other customary and/or reasonable closing documents
requested by the Title Company.  Purchaser may waive compliance on Seller's
part under any of the foregoing items by an instrument in writing.

     d.    At or before the Closing, Purchaser shall deliver to Seller the
following:





9
<PAGE>   10
           i.         the duly executed Assignment of Leases and Assignment of
Intangible Property;

           ii.        such resolutions, authorizations, bylaws or other
corporate and/or partnership documents or agreements relating to Purchaser as
shall be required by Title Company;

           iii.       any other customary and/or reasonable closing documents
requested by the Title Company;

           iv.        in sufficient time to permit an 8:00 a.m. (Dallas time)
Closing, the balance of the Purchase Price in cash or other immediately
available funds, subject to prorations and adjustments as set forth herein.

     e.    Seller and Purchaser shall each deposit such other instruments as
are reasonably required by the escrow holder or otherwise required to close the
escrow and consummate the acquisition of the Property in accordance with the
terms hereof.  Seller and Purchaser hereby designate Title Company as the
"Reporting Person" for the transaction pursuant to Section 6045(e) of the
Internal Revenue Code and the regulations promulgated thereunder and agree to
execute such documentation as is reasonably necessary to effectuate such
designation.

     f.    The following are to be apportioned as of the Closing Date, as
follows:

           i.         RENT.  Rent for the current month under the Leases shall
be apportioned as of the Closing Date, regardless of whether or not such rent
has been paid to Seller.  With respect to any rent arrearages arising under the
Leases, after Closing Purchaser shall pay on or before the 15th day of each
calendar month to Seller any rent actually collected during the preceding month
that is applicable to the period preceding the Closing Date; provided, however,
that all rent collected by Purchaser shall be applied first to all unpaid rent
accruing after the Closing Date, and then to unpaid rent accruing prior to the
Closing Date.  Purchaser shall use reasonable efforts for a period of six (6)
months after Closing to recover rent arrearages, provided that Purchaser shall
not be obligated to sue any Tenant, evict any Tenant or institute any other
legal or quasi-legal proceeding against any Tenant.  Seller shall not be
permitted to take any steps to recover any rent arrearages after Closing,
provided that Seller shall have the right to commence suit against a Tenant to
recover rent arrearages for a period of six (6) months after the Closing and
prosecute such suit to completion and Seller shall have the right to sue a
Tenant at any time after such Tenant's Lease has expired or otherwise
terminates, provided that in no event shall Seller have the right to bring
either an unlawful detainer action or seek recourse to a Tenant's security
deposit transferred to Purchaser.

           ii.        LEASING COSTS; TENANT INDUCEMENTS.  Seller shall pay all
leasing commissions and tenant improvement costs that arise in connection with
any Lease executed on or before the Contract Date.  With respect to any new
Lease or Lease





10


<PAGE>   11
extension or expansion entered into by Seller between the Contract Date and the
Closing Date and approved by Purchaser pursuant to the terms of Paragraph 15(a)
below, in the event that Seller incurs or pays any costs or expenses for
leasing commissions and/or tenant allowances or improvements and/or free rent
(collectively, "New Leasing Costs") in connection with any such new Lease or
such extension or expansion in excess of the gross rental (including base rent,
additional rent and pass-throughs) (collectively, "New Leasing Revenue")
received by Seller with respect to such new Lease or such extension, Seller
shall be entitled to a credit at the Closing for the difference between the New
Leasing Costs and the New Leasing Revenue.  With respect to any free rent
applicable to the period after the Closing that arises under any new Lease or
Lease extension or expansion entered into by Seller between the Contract Date
and the Closing Date and approved by Purchaser pursuant to the terms of
Paragraph 15(a) below, such free rent shall be prorated between Seller and
Purchaser based on the number of months (or fractional months) in such new
Lease or such extension or expansion that are prior to the Closing Date and the
number of such months (or fractional months) that are after the Closing Date.

           iii.       SECURITY DEPOSITS; PREPAID RENT.  Purchaser shall be
entitled to a credit against the Purchase Price for the total sum of all
security deposits (and interest earned thereon) that are required to be
returned to the Tenants under the terms of the respective Leases.
Additionally, Purchaser shall be entitled to a credit against the Purchase
Price for the total sum of all free rent, operating expense abatements, or
other unexpired concessions under any Leases executed prior to the Contract
Date to the extent they apply to any period after the Closing.

           iv.        OTHER TENANT CHARGES.  For all items subject to proration
for which the landlord receives reimbursement from the tenants as common area
maintenance charges ("CAM Charges"), it is acknowledged that Seller has prepaid
certain CAM Charges and already received reimbursement on account of certain
estimated CAM Charges for the period prior to Closing and Purchaser will
similarly make certain payments and receive reimbursements on account of CAM
Charges for the period after Closing.  Seller shall be responsible for
collection of all estimated CAM Charges, including all delinquent amounts,
payable by the tenants prior to Closing, and Purchaser shall be responsible for
collection of all estimated CAM Charges, including delinquent amounts, payable
by the tenants after Closing.  Consistent with the foregoing sentence,
Purchaser and Seller shall prorate the expense items which are subject to
reimbursement pursuant to the CAM Charges in such a way that Seller shall be
responsible for the payment of all costs and expenses which are intended to be
reimbursed by such CAM Charges for the period prior to Closing and Purchaser
shall be responsible for all such costs and expenses after Closing.  At the end
of the fiscal year applicable to the CAM Charges described in the preceding
sentences of this Section, to the extent that the landlord has received excess
CAM Charges and is obligated to reimburse to the tenants any portion of the
excess CAM charges collected by Seller, Seller shall, within ten (10) days of
written demand therefor, reimburse to Purchaser the portion of such excess CAM
Charges which have been paid to and retained by Seller.  In the event that at
the end of the fiscal year





11
<PAGE>   12
applicable to such CAM Charges, tenants on the Property are obligated to pay to
the landlord any sums on account of an underpayment of CAM Charges, Purchaser
shall pay to Seller immediately upon receipt thereof Seller's prorata share of
such reimbursement by the tenants.  Purchaser shall deliver to Seller at the
same time that such notices are delivered to the tenants any accounting or
reconciliation of the CAM Charges for the fiscal year in which the Closing
occurs.

           v.         UTILITY CHARGES.  Seller shall be responsible for the
cost of all utilities used prior to the Closing Date, except to the extent such
utility charges are billed to and paid by tenants directly.

           vi.        OTHER APPORTIONMENTS; CLOSING COSTS.  Amounts payable
under the Assumed Contracts, annual or periodic permit and/or inspection fees
(calculated on the basis of the period covered), and liability for other
Property operation and maintenance expenses and other recurring costs shall be
apportioned as of the Closing Date.  Seller shall pay all transfer taxes and
sales tax (if any) on the Personal Property.  Seller shall pay the premium for
the Title Policy, provided that Purchaser shall pay the cost of the
Endorsements.  Purchaser acknowledges that if title to the Property and the
"Property" described and defined in the Other Agreements is taken in the name
of the same entity or entities, and unless business reasons (e.g. financing
requirements) dictate otherwise as determined by Purchaser in its good faith
discretion, Purchaser shall obtain one title policy covering both the Property
and the "Property" described and defined in the Other Agreements.  Seller and
Purchaser shall each pay fifty percent (50%) of all escrow and recording and
notary fees.  Seller shall be responsible for all costs incurred in connection
with the prepayment or satisfaction of any loan secured by the Property,
including, without limitation, any prepayment fees, penalties or charges.  All
other costs and charges of the escrow for the sale not otherwise provided for
in this Subparagraph 7(f)(vi) or elsewhere in this Agreement shall be allocated
in accordance with the applicable closing customs for Dallas County, Texas.

           vii.       REAL ESTATE TAXES AND SPECIAL ASSESSMENTS.  General real
estate taxes payable for 1996 and all prior years (including subsequent taxes
and assessments for prior years due to change in land usage or ownership) shall
be paid by Seller.  General real estate taxes payable for 1997 shall be
prorated by Seller and Purchaser as of the Closing Date.  If the amount of
general real estate taxes for 1997 cannot be determined on the Closing Date,
Seller shall deposit with the Title Company, from the Purchase Price, an amount
equal to Seller's proportionate share of the 1997 taxes based upon the most
current estimate of such taxes, assuming for estimating purposes that the
Property shall be fully assessed.  Such deposit shall be held in escrow and all
interest earnings on such deposit shall be paid to Seller.  The Title Company
shall retain such deposit to pay Seller's share of the actual general real
estate taxes payable for 1997, paying any excess over to Seller.  Seller shall
pay any deficiency, when such general real estate taxes are known.





12


<PAGE>   13
           viii.      PRELIMINARY CLOSING ADJUSTMENT.  Seller and Purchaser 
shall jointly prepare a preliminary Closing adjustment on the basis of the
Leases and other sources of income and expenses, and shall deliver such
computation to Title Company not less than 10 days prior to Closing.

           ix.        POST-CLOSING RECONCILIATION.  If any of the aforesaid
prorations cannot be calculated accurately on the Closing Date, then they shall
be calculated as soon after the Closing Date as feasible.  Either party owing
the other party a sum of money based on such subsequent proration(s) shall
promptly pay said sum to the other party, together with interest thereon at the
rate of the lesser of (A) two percent (2%) over the average "prime rate" (as
announced from time to time in the Wall Street Journal) per annum or (B) the
highest legally permitted rate, from the Closing Date to the date of payment if
payment is not made within ten (10) days after delivery of a bill therefor.

    SURVIVAL.         The provisions of this Subparagraph 8(f) shall survive
the Closing.

similar in type and character to the Property.

The representations and warranties set forth in this Paragraph 10 shall survive
the Closing for the period set forth in Paragraph 17(e) below.

11.  Other Agreements.

     a.    Notwithstanding anything to the contrary in this Agreement, but
subject to the provisions of Paragraph 11(b) below, it shall be a condition
precedent to both Purchaser's obligation to purchase the Property hereunder and
to Seller's obligation to sell the Property hereunder that the "Closing" under
and as defined in each of those three other Purchase Agreements dated as of
even date herewith and identified on Schedule 3 attached hereto (the "Other
Agreements") occurs concurrently with the Closing hereunder.  The parties
acknowledge and agree that a default by Seller under this Agreement shall be
deemed a default of each of the "Sellers" under each of the Other Agreements
and that a default by a "Seller" under any of the Other Agreements shall be
deemed a default by Seller hereunder.  The parties further acknowledge and
agree that a default by Purchaser under this Agreement shall be deemed a
default of each of the "Purchasers" under each of the Other Agreements and that
a default by a "Purchaser" under any of the Other Agreements shall be deemed a
default by Purchaser hereunder.

     b.    Notwithstanding anything to the contrary provided in Paragraph
11(a) above or elsewhere in this Agreement or any Other Agreement, in the event
that (i) Purchaser discovers during the Due Diligence Period that a Constituent
Parcel (as defined below) is in material violation of any Environmental Law
(but only if Seller fails to cure such violation prior to the Closing Date, as
such may be extended pursuant to this Paragraph 11(b), and Seller is unwilling
to give Purchaser a credit at Closing in such amount as the parties agree upon
will compensate Purchaser for such matter, it being acknowledged by the parties
hereto that Seller shall not be obligated hereunder to elect to cure any such
violation or offer to give Purchaser such a credit), (ii) Purchaser discovers
during the Due Diligence Period that there is a material defect in title that
adversely affects the marketability or financability of the Constituent Parcel
(but only if Seller fails to remedy such defect prior to the Closing Date, as
such may be extended pursuant to this Paragraph 11(b), and Seller is unwilling
to give Purchaser a credit at Closing in such amount as the parties agree upon
will compensate Purchaser for such matter, it being acknowledged by the parties
hereto that Seller shall not be obligated hereunder to elect to remedy any such
defect or offer to give Purchaser such a credit), (iii) Purchaser determines
during the Due Diligence Period that the net operating income derived from the
Property and the "Property" described and defined in the Other Agreements
differs in





16


<PAGE>   17
any material respect in the aggregate from that set forth in any materials
delivered to Purchaser by Seller or its agents prior to Purchaser's execution
of this Agreement or on the Rent Roll (as defined below) and one-third (() or
more of such discrepancy is attributable to any Constituent Parcel (but only to
the extent Seller is unwilling to give Purchaser a credit at Closing in an
amount equal to such loss of income, capitalized at the same rate as that
reflected by the Purchase Price, it being acknowledged by the parties hereto
that Seller shall not be obligated hereunder to offer to give Purchaser such a
credit), (iv) any of Seller's representations and warranties is not true and
correct in all material respects at Closing with respect to a Constituent
Parcel, (v) Purchaser discovers during the Due Diligence Period that there is a
material defect in the physical condition of a Constituent Parcel as disclosed
in an independent third party structural or physical report obtained by
Purchaser (but only if Seller fails to repair all such physical conditions
prior to the Closing Date, as such may be extended pursuant to this Paragraph
11(b), and Seller is unwilling to give Purchaser a credit at Closing in such
amount as the parties agree upon will compensate Purchaser for such matter, it
being acknowledged by the parties hereto that Seller shall not be obligated
hereunder to elect to repair such conditions or offer to give Purchaser such a
credit), or (vi) Purchaser elects to terminate this Agreement as to a
Constituent Parcel pursuant to Paragraph 12 below, Purchaser shall have the
right to terminate this Agreement as to such affected Constituent Parcels only
(each such Constituent Parcel being referred to herein as a "Removed Parcel"),
in which event this Agreement shall be amended to delete all references to the
Removed Parcel(s), the Purchase Price shall be reduced by the amount allocated
to the Removed Parcel(s) as set forth on Schedule 4 attached hereto, and this
Agreement and the Other Agreements shall otherwise remain in full force and
effect; provided, however, that with respect to the circumstances described in
clauses (i), (ii), (iii) and (v) above, Purchaser's right of termination shall
be conditioned upon Purchaser's informing Seller in writing prior to the end of
the Due Diligence Period that Purchaser will terminate this Agreement as to
such affected Constituent Parcel if such matter is not cured or remedied or
Purchaser is not otherwise compensated, as applicable, prior to the Closing.
Seller shall have the right to extend the Closing Date with respect to any
affected Parcel for up to sixty (60) days to remedy or cure any such
objectionable matter, provided that Seller (i) delivers written notice to
Purchaser within five (5) days after the end of the Due Diligence Period, which
notice shall state that Seller is electing to extend the Closing Date and that
Seller will use all commercially reasonable efforts to cure or remedy such
matter, and (ii) thereafter diligently proceeds to attempt to cure or remedy
such matter.  The sixty (60) day period set forth in the immediately preceding
sentence shall run concurrent with the sixty (60) day period set forth in
Paragraph 6(c) above.

     c.    Notwithstanding anything to the contrary provided in Paragraph 11(a)
above or elsewhere in this Agreement or any Other Agreement, in the event that
the Removed Parcel(s) constitute(s) the entire Property, Purchaser shall have
the right to terminate this Agreement in its entirety, but elect to keep the
Other Agreements in full force and effect.





17
<PAGE>   18
     d.    As used herein, the term "Constituent Parcel" shall mean one of the
projects identified on Schedule 4 attached hereto, together with the Land and
all other portions of the Property properly allocable thereto.

12.  Risk of Loss.

     a.    Purchaser shall be bound to purchase the Property for the full
Purchase Price as required by the terms hereof, without regard to the
occurrence or effect of any damage to the Property or destruction of any
improvements thereon or condemnation of any portion of the Property, provided
that (i) the cost to repair any such damage or destruction to a Constituent
Parcel, or the diminution in the value of the remaining Property as a result of
a partial condemnation, does not exceed $250,000 (and the cost to repair all
such damage or destruction to, or the diminution in value of, the Property and
the "Property" described and defined in the Other Agreements, in the aggregate,
does not exceed $1,000,000), and (ii) upon the Closing, there shall be a credit
against the Purchase Price due hereunder equal to the amount of any insurance
proceeds or condemnation awards collected by Seller as a result of any such
damage or destruction or condemnation, less any sums reasonably expended by
Seller toward the restoration or repair of the affected Property, and, if the
proceeds or awards have not been collected as of the Closing, then such
proceeds or awards shall be assigned to Purchaser.

     b.    If the amount of the damage or destruction or condemnation as
specified in Paragraph 12(a) above exceeds $250,000 with respect to any
Constituent Parcel, then Purchaser may, at its option to be exercised within
twenty (20) days of Seller's written notice of the occurrence of the damage or
destruction or the commencement of condemnation proceedings, either terminate
this Agreement in its entirety or solely with respect to such Constituent
Parcel or consummate the purchase for the full Purchase Price as required by
the terms hereof.  Similarly, if the amount of the damage or destruction or
condemnation as specified in Paragraph 12(a) above exceeds $1,000,000 with
respect to the Property and the "Property" described and defined in the Other
Agreements, in the aggregate, then Purchaser may, at its option to be exercised
within twenty (20) days of Seller's written notice of the occurrence of the
damage or destruction or the commencement of condemnation proceedings, either
terminate this Agreement in its entirety or consummate the purchase for the
full Purchase Price as required by the terms hereof.  If Purchaser elects to
terminate this Agreement in its entirety or fails to give Seller written notice
within such 20-day period that Purchaser will proceed with the purchase, then
the Deposit shall be immediately returned to Purchaser and neither party shall
have any further rights or obligations hereunder, except to the extent
expressly otherwise set forth herein.  If Purchaser elects to terminate this
Agreement solely with respect to such affected Constituent Parcel, the
provisions of Paragraph 11(b) above shall control.  If Purchaser elects to
proceed with the purchase as to the entire Property, then upon the Closing,
there shall be a credit against the Purchase Price due hereunder equal to the
amount of any insurance proceeds or condemnation awards collected by Seller as
a result of any such damage or destruction or condemnation, less any sums
reasonably





18


<PAGE>   19
expended by Seller toward the restoration or repair of the affected Property,
and, if the proceeds or awards have not been collected as of the Closing, then
such proceeds or awards shall be assigned to Purchaser.

     c.    In the event that Purchaser is required to or elects to purchase the
entire Property following any damage or destruction or condemnation of the
Property pursuant to Paragraph 12(a) or (b) above, Seller shall also provide
Purchaser with a credit against the Purchase Price in an amount equal to any
deductible or uninsured amount; provided, however, in no event shall Seller be
required to provide Purchaser with a credit pursuant to this Paragraph 12(c) in
an amount that exceeds $250,000 with respect to any Constituent Parcel or that
exceeds $1,000,000 with respect to the Property and the "Property" described
and defined in the Other Agreements, in the aggregate.  If it is determined
that the deductible or uninsured amount is greater than $250,000 (or
$1,000,000, as applicable), Seller shall notify Purchaser in writing as soon as
reasonably possible following such determination whether or nor Seller is
willing to provide Purchaser with a credit against the Purchase Price in the
full amount of such deductible or uninsured amount.  In the event that Seller
is unwilling to provide Purchaser with a credit in such full amount, Purchaser
shall have the right to terminate this Agreement by delivering written notice
to Seller within twenty (20) days after Purchaser's receipt of such notice from
Seller.  If Purchaser elects to terminate this Agreement or fails to give
Seller written notice within such twenty (20) day period that Purchaser will
proceed with the purchase, the Deposit shall be immediately returned to
Purchaser and neither party shall have any further obligations hereunder,
except to the extent expressly otherwise set forth herein.

13.  Possession.

    Possession of the Property shall be delivered to Purchaser on the Closing
Date subject only to the rights of Tenants under the Leases, provided, however,
that prior to the Closing Date Seller shall afford authorized representatives
of Purchaser (as well as any actual or prospective lender to Purchaser)
reasonable access to the Property, upon 24 hours notice, for purposes of
satisfying Purchaser (and such lender) with respect to the representations,
warranties and covenants of Seller contained herein and with respect to
satisfaction of any Diligence Period Condition or any Condition Precedent
(including, without limitation, the Condition Precedent set forth in Paragraph
6(d) above) and for the purpose of conducting Tenant interviews, provided that
prior to entering the Property Purchaser shall (i) obtain comprehensive general
liability insurance in an amount not less than $1,000,000 naming Seller as an
additional insured and (ii) provide a copy of such policy or a certificate
evidencing such coverage to Seller.  Purchaser hereby agrees to indemnify and
hold Seller harmless from any damage or injury to persons or property caused by
Purchaser or its authorized representatives during their entry and
investigations prior to the Closing, provided the foregoing shall not require
Purchaser to indemnify Seller or any other person with respect to any
conditions that are discovered by Purchaser as opposed to being first caused by
Purchaser.  If this Agreement is terminated, Purchaser shall repair the damage
caused by Purchaser's entry and investigations, provided the





19
<PAGE>   20
foregoing shall not require Purchaser to repair or remediate any conditions
that are discovered by Purchaser as opposed to being first caused by Purchaser.
The foregoing indemnity shall survive the termination of this Agreement or the
Closing, as applicable.

14.  Maintenance of the Property; Miscellaneous Covenants.

    Between the Contract Date and the Closing, Seller shall perform all of the
landlord's obligations under the Leases and shall otherwise operate and
maintain the Property in the same manner as before the making of this
Agreement, as if Seller were retaining the Property.  Seller shall promptly
notify Purchaser of any condemnation, environmental, zoning or other land-use
regulation proceedings of which Seller becomes aware, as well as any notices of
violations of any Laws relating to the Property of which Seller becomes aware
and any litigation of which Seller becomes aware that arises out of the
ownership of the Property or that might detrimentally affect the value or the
use or operation of the Property or the ability of Seller to perform its
obligations hereunder.  Following the Contract Date, Seller shall continue to
prepare Operating Statements (as defined in Exhibit G hereto) for the Property
as to all time periods subsequent to the dates of the Operating Statements
delivered to Purchaser as part of the Delivery Items and prior to the Closing
Date, which Operating Statements shall be delivered to Purchaser within a
reasonable period of time following the end of the period with respect to which
such Operating Statements are prepared, even if prepared after Closing.
Through the Closing Date, Seller shall maintain or cause to be maintained, at
Seller's sole cost and expense, all policies of insurance currently in effect
with respect to the Property (or comparable replacements thereof).

15.  Purchaser's Consent to New Contracts Affecting the Property; Termination of
     Existing Contracts.

     a.    Seller shall not, after the Contract Date, enter into any Lease or
contract, or any amendment thereof, or permit any Tenant to enter into any
sublease, assignment or agreement pertaining to the Property, or waive any
rights of Seller under any contract or Lease, without in each case obtaining
Purchaser's prior written consent thereto, which consent in the case of any
Lease shall include approval of the financial condition of the proposed tenant,
the configuration of the space to be leased, and the terms of such Lease
(including, without limitation, the rent and any concessions provided under
such proposed Lease), and which consent shall not be unreasonably withheld by
Purchaser.  Seller shall be entitled, without the consent of Purchaser, to
enter into, amend or otherwise deal with service contracts and similar
agreements that are not Assumed Contracts in the ordinary course of business
that are terminable on not more than thirty (30) days' prior notice and which
shall not be binding on Purchaser after the Closing Date.  Seller shall deliver
to Purchaser, together with any request for approval of a new Lease, a copy of
the proposed Lease, a description of the proposed Tenant and its proposed use
of the premises and whatever financial information on the proposed Tenant
Seller has received, as well as any additional information reasonably requested
by





20


<PAGE>   21
Purchaser (including, without limitation, if applicable, an environmental
questionnaire).  Notwithstanding anything to the contrary provided in this
Subparagraph 15(a), if Purchaser fails to respond in writing with respect to
any such new Lease or other action requiring Purchaser's consent under this
Subparagraph 15(a) within five (5) business days after Purchaser's receipt of
such request and information, Purchaser shall be deemed to have approved such
new Lease or other action.

     b.    Seller shall terminate prior to the Closing, at no cost or expense
to Purchaser, any and all management agreements, service contracts or similar
agreements affecting the Property that are not Assumed Contracts.

     c.    Seller shall not, after the Contract Date, create any new
encumbrance or lien affecting the Property other than liens and encumbrances
(i) that are reasonably capable of being discharged prior to the Closing and
(ii) that in fact will be and are discharged prior to the Closing.

16.  Cooperation with Purchaser.

     Seller shall cooperate and do all acts as may be reasonably required or
requested by Purchaser with regard to the fulfillment of any Condition
Precedent including execution of any documents, applications or permits
reasonably requested by Purchaser and, to the extent requested by Purchaser,
agrees to cooperate with Purchaser's efforts to obtain subordination,
non-disturbance and attornment agreements from the Tenants.  Seller hereby
authorizes Purchaser and its agents to make all inquiries with and applications
to any third party, including any governmental authority, as Purchaser may
reasonably require to complete its due diligence.

17.  Miscellaneous.

     a.    NOTICES.  Any notice, consent or approval required or permitted to
be given under this Agreement shall be in writing and shall be deemed to have
been given upon (i) hand delivery, (ii) one (1) business day after being
deposited with Federal Express or another reliable overnight courier service,
with receipt acknowledgment requested, (iii) upon receipt if transmitted by
facsimile telecopy, or (iv) upon receipt or refused delivery deposited in the

to the other.

      b.    BROKERS AND FINDERS.  Neither party has had any contact or dealings
regarding the Property, or any communication in connection with the subject
matter of this transaction, through any real estate broker or other person who
can claim a right to a commission or finder's fee in connection with the sale
contemplated herein, except for Cushman & Wakefield of Texas, Inc. ("Broker"),
whose commission shall be paid by Seller pursuant to the terms of a separate
agreement between Seller and Broker.  In the event that any other broker or
finder makes a claim for a commission or finder's fee based upon any contact,
dealings or communication, the party whose conduct is the basis for the broker
or finder making its claim shall indemnify, defend and hold harmless the other
party against and from any commission, fee, liability, damage, cost and
expense, including without limitation attorneys' fees, arising out of or
resulting from any such claim. The provisions of this paragraph shall survive
the Closing.

      c.    SUCCESSORS AND ASSIGNS.  This Agreement shall be binding upon, and
inure to the benefit of, the parties hereto and their respective successors,
heirs, administrators and assigns.  Notwithstanding the foregoing, Purchaser
shall not have the right, without the prior written approval of Seller, to
assign this Agreement in whole or in part, provided that Purchaser may assign
this Agreement upon notice to Seller (but without any requirement of obtaining
Seller's consent) in whole or in part to (i) one or more entities in which Marc
R. Brutten, Jay H. Shidler and/or James C. Reynolds, directly or indirectly,
has an ownership interest, and/or (ii) an entity controlled or managed by, or
otherwise affiliated with, Angelo Gordon & Co., provided that such assignee(s)
shall assume all of the obligations of Purchaser hereunder and the foregoing
shall not act as a release of the party originally designated as Purchaser
hereunder.  To the extent that any indemnity set forth in this Agreement is
made for the benefit of Purchaser or Seller, the term "Purchaser" or "Seller",
as applicable, as it pertains to an indemnified party only, shall





22


<PAGE>   23
include the managers, members, investors, affiliates, lenders, officers,
directors, shareholders, partners, trustees, beneficiaries, agents and
employees of such party and their respective heirs, representatives, successors
and assigns.

     d.    AMENDMENTS.  Except as otherwise provided herein, this Agreement may

Purchaser.

     e.    CONTINUATION AND SURVIVAL OF REPRESENTATIONS AND WARRANTIES, ETC.
All representations and warranties by the respective parties contained herein
or made in writing pursuant to this Agreement are intended to and shall remain
true and correct as of the time of Closing, shall be deemed to be material,
and, together with all conditions, covenants and indemnities made by the
respective parties contained herein or made in writing pursuant to this
Agreement, shall survive the execution and delivery of this Agreement and the
Closing for a period of 12 months, or, to the extent the context requires,
beyond any termination of this Agreement.  In the event that a claim is not
made with respect to a breach of a representation, warranty or covenant set
forth herein within such 12 month period, such claim shall be deemed waived.

     f.    GOVERNING LAW.  This Agreement shall be governed by and construed in
accordance with the laws of the State of Texas.

     g.    MERGER OF PRIOR AGREEMENTS.  This Agreement and the exhibits and
schedules hereto constitute the entire agreement between the parties and
supersede all prior agreements and understandings between the parties relating
to the subject matter hereof.

     h.    ENFORCEMENT.  If either party hereto fails to perform any of its
obligations under this Agreement or if a dispute arises between the parties
hereto concerning the meaning or interpretation of any provision of this
Agreement, then the defaulting party or the party not prevailing in such
dispute shall pay any and all costs and expenses incurred by the other party on
account of such default and/or in enforcing or establishing its rights
hereunder, including, without limitation, court costs and attorneys' fees and
disbursements.  Any such attorneys' fees and other expenses incurred by either
party in enforcing a judgment in its favor under this Agreement shall be
recoverable separately from and in addition to any other amount included in
such judgment, and such attorneys' fees obligation is intended to be severable
from the other provisions of this Agreement and to survive and not be merged
into any such judgment.

     i.    TIME OF THE ESSENCE.  Time is of the essence of this Agreement.

     j.    SEVERABILITY.  If any provision of this Agreement, or the
application thereof to any person, place, or circumstance, shall be held by a
court of competent jurisdiction to be invalid, unenforceable or void, the
remainder of this Agreement and such provisions as applied to other persons,
places and circumstances shall remain in full force and effect.

     k.    MARKETING.  During the term of this Agreement, Seller shall not list
the Property with any broker or otherwise solicit or make or accept any offers
to sell the





23
<PAGE>   24
Property, engage in any discussions or negotiations with any third party with
respect to the sale or other disposition of the Property, or enter into any
contracts or agreements (whether binding or not) regarding any disposition of
the Property.

     l.    CONFIDENTIALITY.  Each party agrees to maintain in confidence, and
not to disclose to any third party, the information contained in this Agreement
or pertaining to the sale contemplated hereby and the information and data
furnished or made available by Seller to Purchaser, its agents and
representatives in connection with Purchaser's investigation of the Property
and the transactions contemplated by the Agreement; provided, however, that
each party, its agents and representatives may disclose such information and
data (a) to such party's accountants, attorneys, prospective lenders,
accountants, partners, consultants and other advisors in connection with the
transactions contemplated by this Agreement (collectively "Representatives") to
the extent that such Representatives reasonably need to know (in Purchaser's or
Seller's reasonable discretion) such information and data in order to assist,
and perform services on behalf of, Purchaser or Seller; (b) to the extent
required by any applicable statute, law, regulation, governmental authority or
court order; and (c) in connection with any litigation that may arise between
the parties in connection with the transactions contemplated by this Agreement.
In the event of any conflict between the terms of this Section 17(l) and the
terms of the Confidentiality Agreement referenced in Section 17(g) above, the
terms of said Confidentiality Agreement shall control.  Each party shall
consult with the other party prior to making any press release or other
disclosure intended for general circulation regarding the transactions
contemplated hereunder.  In no event shall any such disclosure or press release
contain the purchase price.

     m.    SECTION 1031 EXCHANGE.  It is presently contemplated that Purchaser
and Seller may each desire to effectuate a tax-deferred exchange (also known as
a "1031" exchange) (an "Exchange") in connection with the purchase and sale of
the Property.  Purchaser and Seller hereby agree to cooperate with each other
in connection with one or more such Exchanges, provided that:

           i.         All documents executed by a party in connection with the
Exchange shall be subject to the prior reasonable approval of that party and
shall recognize that that party is acting solely as an accommodating party to
such Exchange, shall have no liability with respect thereto, and is making no
representation or warranty that the transactions qualify as a tax-free exchange
under Section 1031 of the Internal Revenue Code or any applicable state or
local laws and shall have no liability whatsoever if any such transactions
fails to so qualify.

           ii.        Such Exchange shall not result in Purchaser or Seller
incurring any additional costs or liabilities.





24


<PAGE>   25
           iii.       In no event shall Purchaser or Seller be obligated to
acquire any property or otherwise be obligated to take title, or appear in the
records of title, to any property in connection with such Exchange.

           iv.        In no event shall Purchaser's or Seller's consummation of
such Exchange constitute a condition precedent to that party's obligations
under this Agreement, and Purchaser's or Seller's failure or inability to
consummate such Exchange for any reason or for no reason at all shall not be
deemed to excuse or release that party from its obligations under this
Agreement.

     n.    POST-CLOSING COOPERATION.  If it becomes reasonably necessary to do
so in order to comply with applicable securities laws or the rules or
regulations of the Securities and Exchange Commission, for a period of four (4)
years after the Closing Date, Purchaser and its agents shall have the right, at
Purchaser's sole cost and expense, to inspect and obtain copies of Seller's
books and records supporting the operation of the Property for the period of
three (3) full calendar years preceding the calendar year which includes the
Closing Date.  Purchaser shall give reasonable prior written notice to Seller
when Purchaser wishes to exercise its right to inspect such books and records.
Such inspection shall take place at the office of Seller during normal business
hours on a date and at a time reasonably convenient to Seller and Purchaser.
The provisions of this Paragraph 17(n) shall survive the Closing.

     o.    RETURN OF DOCUMENTS.  In the event that this Agreement terminates,
Purchaser shall return to Seller all due diligence materials and all copies
thereof delivered by Seller to Purchaser hereunder and, subject to any
restrictions on transferability set forth therein, shall deliver to Seller
copies of all reports generated by Purchaser's contractors, engineers and other
third party professional (non-legal) consultants, all of which reports shall be
delivered by Purchaser without any representation or warranty as to the
contents thereof.

     IN WITNESS WHEREOF, the parties hereto have executed this Agreement as of

amended hereby) is not satisfied, including, without limitation, the Condition
Precedent set forth in Paragraph 6(b) thereof relating to the delivery of

         7.      No other Amendment; Conflict.  Except as set forth in this
Second Amendment, the provisions of the Purchase Agreement shall remain in full
force.  If any provision of this Second Amendment conflicts with any provision
of the Purchase Agreement, then the provisions of this Second Amendment shall
prevail.

         8.      Counterparts.  This Second Amendment may be signed in multiple

                               PURCHASE AGREEMENT

       THIS AGREEMENT is made and entered into as of this 2nd day of July,
1997, by and between SHIDLER WEST INVESTMENT CORPORATION, a Delaware
corporation ("Purchaser"), and MERIT VV 1995 INDUSTRIAL PORTFOLIO LIMITED
PARTNERSHIP, a Texas limited partnership (Seller").

       IN CONSIDERATION of the respective agreements hereinafter set forth,
Seller and Purchaser hereby agree as follows:

1.     Purchase and Sale.

       Seller agrees to sell and convey to Purchaser, and Purchaser agrees to
purchase from Seller, on the terms and conditions set forth in this Agreement,
the Property.  As used herein, the term the "Property" shall mean,
collectively:  (a) the parcels of land described in Exhibit A attached hereto
(collectively, the "Land"), together with all rights, easements and interests
appurtenant thereto including, but not limited to, any streets or other public
ways adjacent to the Land and any development rights, water or mineral rights
owned by, or leased to, Seller; (b) all improvements located on the Land,
including, but not limited to, those certain three (3) buildings identified on
Schedule 1 attached hereto and all other structures, systems, and utilities
associated with, and utilized by Seller in the ownership and operation of such
building(s) (all such improvements, together with such building(s), being
referred to herein as the "Improvements"), but excluding improvements, if any,
owned by tenants of such building(s); (c) all personal property owned by
Seller, located on or in the Land or Improvements, or used in connection with
the operation and maintenance of the Property (the "Personal Property"),
including, without limitation, all personal property listed on Exhibit B
attached hereto; (d) all building materials, supplies, hardware, carpeting and
other inventory maintained in connection with Seller's ownership and operation
of the Property (the "Inventory"); (e) all trademarks, tradenames, and
entitlements and other intangible property used or useful in connection with
the foregoing, including, without limitation, all of Seller's right, title and
interest in any and all warranties and guaranties relating to the Property, but
excluding all rights to use the name "Merit" (the "Intangible Personal
Property"); and (f) Seller's interest in all leases and other agreements to
occupy all or any portion of the Property that are in effect on the Contract
Date (defined below) or into which Seller enters prior to Closing (defined
below), but pursuant to the terms of this Agreement (as such may have been
amended, modified or supplemented, the "Leases").

2.     Purchase Price; Independent Contract Consideration.

              a.     The purchase price of the Property shall be Six Million
Nine Hundred Fifty Thousand Dollars ($6,950,000.00) (the "Purchase Price").
The Purchase Price shall be paid to Seller at Closing, plus or minus prorations
and other adjustments hereunder, in immediately available funds.




1
<PAGE>   2
              b.     The Purchase Price shall be paid as follows:

                     i.     Upon mutual execution of this Agreement, Purchaser
shall deliver to Commonwealth Land Title Company of Dallas ("Title Company") a
deposit in the amount of One Hundred Fifty Thousand Dollars ($150,000.00) (the
"Initial Deposit; and, together with the Extension Deposit (as defined below),
if applicable, the "Deposit").  The Deposit shall be held in an interest-
bearing account and interest accruing thereon shall be held for the account of
Purchaser.  In the event the sale of the Property as contemplated hereunder is
consummated, the Deposit plus interest accrued thereon shall be delivered to
Seller at the Closing and credited against the Purchase Price.

                     ii.    Prior to or contemporaneous with the execution
hereof by Purchaser and Seller, Purchaser has paid to Seller One Hundred
Dollars ($100.00) (the "Independent Contract Consideration"), which amount
Seller and Purchaser bargained for and agreed to as consideration for Seller's
execution and delivery of this Agreement.  The Independent Contract
Consideration is non-refundable and in addition to any other payment or deposit
required by this Agreement, and Seller shall retain the Independent Contract
Consideration notwithstanding any other provision of this Agreement to the
contrary; provided, however, that if the Closing shall occur hereunder, then
the Independent Contract Consideration shall be applied to the Purchase Price.

                     iii.   The balance of the Purchase Price shall be paid to
Seller at the closing of the purchase and sale contemplated hereunder (the
"Closing").

3.     Title to the Property.

              a.     At the Closing, Seller shall convey to Purchaser
indefeasible and insurable fee simple title to the Land and the Improvements,
by one or more duly executed and acknowledged special warranty deeds in the
form attached hereto as Exhibit C (collectively, the "Deed").  Evidence of
delivery of indefeasible and insurable fee simple title shall be the issuance
by Title Company to Purchaser of a Texas Owner's Policy of Title Insurance
(Form T-1) in the amount of the Purchase Price (the "Title Policy"), insuring
fee simple title to the Land and the Improvements in Purchaser, subject only to
such exceptions as Purchaser shall approve pursuant to Subparagraph 5(a) below
(the "Permitted Exceptions").  The Title Policy shall contain such special
endorsements as Purchaser may reasonably require, including, without
limitation, the amendment of the survey exception to read "shortages in area"
only (the "Endorsements").  The Title Company shall also provide for
reinsurance with direct access with such companies and in such amounts as
Purchaser shall reasonably request.

              b.     At the Closing, Seller shall transfer title to the
Personal Property and the Inventory by a bill of sale in the form attached
hereto as Exhibit D (the "Bill of Sale"), such title to be free of any liens,
encumbrances or interests, other than the Permitted Exceptions.

<PAGE>   3



              c.     At the Closing, Seller shall transfer title to the
Intangible Personal Property by an assignment of service contracts, warranties
and guaranties and other intangible property in the form attached hereto as
Exhibit E (the "Assignment of Intangible Property") and shall transfer title to
the Leases by an assignment of leases in the form attached hereto as Exhibit F
(the "Assignment of Leases"), such title to be free of any liens, encumbrances
or interests, other than the Permitted Exceptions.

4.     Due Diligence and Time for Satisfaction of Conditions.

       Purchaser shall have the right to commence due diligence with respect to
the Property following the date on which this Agreement is fully executed by
the parties hereto (the "Contract Date") and the due diligence period ("Due
Diligence Period") shall expire on July 30, 1997, provided, however, in the
event that Seller fails to deliver to Purchaser any of the items identified on
Exhibit G attached hereto and identified with an asterisk (the "Delivery
Items") on or before the date that is five (5) days after the Contract Date,
the Due Diligence Period shall be extended with respect to such undelivered
Delivery Item only by one day for each day beyond such fifth (5th) day until
such Delivery Item is delivered to Purchaser.  In addition to the foregoing,
Seller shall, upon 24 hours notice, make available to Purchaser and its
employees, representatives, counsel and consultants access to all of its books,
records and files relating to the Property in Seller's possession or reasonable
control, including, without limitation, all of the items set form on said
Exhibit G other than the Delivery Items, and Seller agrees, to the extent
reasonably feasible, to allow Purchaser to make copies at Seller's office or
the property management office of such items as Purchaser reasonably requests.
As used in this Agreement, the term "reasonable control" mean those items in
the possession of Seller's agents or independent contractors under direct
contract with Seller or its affiliates, and the term "affiliate" means any
entity or person controlled by, controlling or under common control with a
named person or entity.

5.     Diligence Period Conditions.

       The following conditions are precedent to Purchaser's obligation to
purchase the Property and to deliver the Purchase Price (the "Diligence Period
Conditions"):

              a.     Purchaser's review and approval of title to the Property,
as follows.  Seller shall deliver to Purchaser at Seller's sole cost and
expense, within five (5) days after the Contract Date, the following:

                     i.     one or more current standard coverage preliminary
title reports on the Land, issued by Title Company, accompanied by copies of
all documents referred to in the reports (the "Preliminary Reports").  In the
event the Title Company issues any supplements to the Preliminary Reports
during the term of this Agreement, Purchaser shall have five (5) business days
following delivery of any such supplemental report to approve or disapprove in
writing of any exception contained therein and not disclosed in the Preliminary
Reports, or any prior supplement thereto;


3
<PAGE>   4
                     ii.    copies of all existing and proposed easements,
covenants, restrictions, agreements or other documents which affect title to
the Property and which are not disclosed by the Preliminary Reports;

                     iii.   all surveys of the Land and Improvements in
Seller's possession or reasonable control; and

                     iv.    copies of the most recent property tax bills for
the Property.

       Purchaser shall advise Seller, at least ten (10) days prior to the end
of the Due Diligence Period, what exceptions to title, if any, will be accepted
by Purchaser.  Seller shall have five (5) days after receipt of Purchaser's
objections to give Purchaser:  (i) notice that Seller shall use all reasonable
efforts to remove all disapproved exceptions from title on or before the
Closing Date; or (ii) notice that Seller elects not to cause such exceptions to
be removed.  If Seller gives Purchaser notice under clause (ii), Purchaser
shall have five (5) days to elect to proceed with the purchase or terminate
this Agreement.  If Purchaser shall fail to give Seller notice of its election
within said five (5) days, Purchaser shall be deemed to have elected to
terminate this Agreement.  If Seller gives notice under clause (i) above and
fails to remove all such disapproved exceptions prior to the Closing Date
despite using its reasonable efforts and Purchaser is unwilling to accept title
subject to such exception in its sole and absolute discretion, Purchaser shall
have the right to terminate this Agreement.  Notwithstanding anything to the
contrary provided herein, Seller shall be obligated to remove or endorse over
to the reasonable satisfaction of Purchaser prior to Closing all monetary liens
encumbering the Property (or any portion thereof) other than the lien of any
property taxes, not yet due or payable.

              b.     Purchaser's review and approval of the matters described
in Paragraph 4 above and each component thereof as Purchaser shall desire in
its sole and absolute discretion.  Such review shall include an examination for
the presence or absence of Hazardous Material (as defined in Subparagraph 8(j)
below).  Notwithstanding anything to the contrary contained herein, Purchaser
shall not engage in or otherwise conduct any additional environmental studies
or environmental testing or sampling of any kind with respect to the Property
or with respect to the soils or ground water, or other studies which would
require test boring or which testing would otherwise damage or disturb any
portion of the Property, without obtaining Seller's prior written consent
thereto, which consent shall not be unreasonably withheld, delayed or
conditioned.

              c.     Purchaser's review and approval, within the Due Diligence
Period, of a schedule (the "Schedule of Agreements") setting forth an exclusive
list of all of the service contracts and similar agreements affecting the
Property.  Prior to the end of the Due Diligence Period, Purchaser shall
deliver to Seller a list setting forth those service contracts and similar
agreements that shall be assigned to, and assumed by, Purchaser at the Closing
(the "Assumed Contracts").  Purchaser shall have the right, in its sole
discretion, to require the termination of any service contract or similar
agreement that is





4


<PAGE>   5



not an Assumed Contract effective as of the Closing, provided that either (i)
such contract or agreement is terminable by Seller without the payment of any
fee or penalty and Purchaser provides to Seller adequate notice that Purchaser
shall require the termination of such contract or agreement or (ii) the service
provider is an affiliate of Seller or Seller's general partner.

              Prior to the end of the Due Diligence Period, Purchaser shall
deliver written notice (the "Approval Notice") to Seller informing Seller
whether or not Purchaser has approved or waived all of the Diligence Period
Conditions.  Notwithstanding anything in this Agreement to the contrary,
Purchaser shall have the right to terminate this Agreement at any time prior to
the end of the Due Diligence Period in its sole and absolute discretion and for
any or for no reason whatsoever.  If, by the end of the Due Diligence Period,
Purchaser shall not have delivered the Approval Notice to Seller approving or
waiving all of the Diligence Period Conditions, then this Agreement shall
automatically terminate, the Deposit shall be returned to Purchaser and the
parties shall be released from all obligations hereunder.

6.     Conditions to Closing.

       The following conditions are precedent to Purchaser's obligation to
acquire the Property and to deliver the Purchase Price (the "Conditions
Precedent"):

              a.     This Agreement shall not have terminated pursuant to any
other provision hereof, including, without limitation, Paragraph 5 above.

              b.     Seller's obtaining and delivering to Purchaser tenant
estoppel certificates from tenants ("Tenants") occupying all of the rentable
area of the leased premises in the Property that is leased to Tenants, which
certificates shall be in the form of Exhibit I attached hereto (subject only to
such changes and qualifications, including, without limitation, statements
alleging defaults or other matters, as are acceptable to Purchaser in its
reasonable discretion) and shall reflect the terms of the respective Leases,
and which certificates shall be dated (or recertified) no earlier than forty-
five (45) days prior to the Closing Date.  Seller shall deliver to each of the
Tenants of the Property, and shall use its reasonable efforts to obtain from
each of the Tenants, a tenant estoppel certificate in the form attached hereto
as Exhibit I, revised by Seller to reflect the terms of the respective Leases,
and modified to address reasonable, specific concerns arising as a result of
Purchaser's review of the Leases that are conveyed to Seller in writing prior
to the expiration of the Due Diligence Period.  As used in this Section 6(b),
reasonable efforts shall be limited to demand only and Seller shall not be
obligated to institute legal action to require delivery of such estoppel
certificates.  Notwithstanding the foregoing, to the extent that Seller has not
obtained satisfactory estoppel certificates from all of the Tenants despite its
using reasonable best efforts, but Seller has obtained satisfactory estoppel
certificates from all of the Major Tenants and from Tenants (including Major
Tenants) occupying ninety percent (90%) or more of the rentable area of the
leased premises in the Property that is leased to Tenants, then Seller shall
deliver to Purchaser a


5
<PAGE>   6
master landlord estoppel dated as of the Closing Date with respect to all
leased space in the Premises for which a satisfactory tenant estoppel
certificate is not delivered by Seller, which master estoppel certificate shall
be in form and substance (based substantially on Exhibit I hereto) reasonably
satisfactory to Purchaser, and the Condition Precedent set forth in this
Paragraph 6(b) shall be deemed satisfied.  The representations and warranties
set forth in Seller's master estoppel certificate shall survive the Closing as
to each such space until the scheduled expiration date of the current term of
the lease for such space.  In the event Seller shall deliver one or more
estoppel certificates, Seller shall have the right, after the Closing, to
continue to obtain estoppel certificates with respect to such leases.  In the
event Seller is able to obtain an estoppel certificate from a tenant for which
Seller delivered a replacement estoppel certificate, then the obligations of
the Seller under the replacement estoppel certificate shall terminate and be of
no further force or effect as of the date of delivery of the estoppel
certificate from the tenant.  As used herein, the term "Major Tenant" shall
mean a Tenant occupying 10,000 rentable square feet or more of leased space in
the Premises.

              c.     All of Seller's representations and warranties contained
in or made pursuant to this Agreement shall have been true and correct when
made and shall be true and correct as of the Closing Date.  At the Closing
Seller shall deliver to Purchaser a certificate certifying that each of
Seller's representations and warranties contained in Paragraph 8 below are true
and correct as of the Closing Date.  In the event that Seller advises Purchaser
prior to the Closing that any of Seller's representations or warranties set
forth herein is not true and correct as a result of an event occurring after
the Contract Date that is beyond the control of Seller or Seller's employees,
partners, agents or contractors, then Purchaser's sole remedy shall be to
cancel and terminate this Agreement and receive the return of the Deposit or to
waive the condition precedent set forth in this Paragraph 6(c) with respect to
such representation or warranty and, in the event the Closing occurs, Purchaser
shall not be entitled to any reduction in the Purchase Price or recover damages
from Seller with respect to such representation or warranty.  Notwithstanding
anything to the contrary set forth above, in the event that Purchaser advises
Seller prior to the Closing that any of Seller's representations or warranties
set forth herein is not true and correct, Seller shall have the right to elect
to cure such untrue or incorrect representation or warranty prior to the
Closing, and in the event that Seller cures all such untrue or incorrect
representations and warranties prior to the Closing, the Condition Precedent
set forth in this Paragraph 6(c) shall be deemed satisfied.  Seller shall have
the right to extend the Closing Date with respect to any affected Constituent
Parcel Constituent Parcel (as defined below) for up to sixty (60) days to cure
any such untrue or incorrect representations or warranties, provided that
Seller (i) delivers written notice to Purchaser within five (5) days after
Seller receives such notification from Purchaser, which notice shall state that
Seller is electing to extend the Closing Date and that Seller will use all
commercially reasonable efforts to cure such untrue or incorrect representation
or warranty, and (ii) thereafter diligently proceeds to attempt to cure all
such untrue or incorrect representations and warranties.  The sixty (60) day
period set





6
<PAGE>   7
forth in the immediately preceding sentence shall run concurrent with the sixty
(60) day period set forth in Paragraph 11(b) below.

              d.     The physical condition of the Property shall be
substantially the same on the day of Closing as on the date of Purchaser's
execution of this Agreement, reasonable wear and tear and loss by casualty
excepted (subject to the provisions of Paragraph 12 below), and, as of the day
of Closing, there shall be no litigation or administrative agency or other
governmental proceeding of any kind whatsoever, pending or threatened, which
after Closing would materially adversely affect the value of the Property or
the ability of Purchaser to operate the Property in the manner in which it is
currently being operated, and no proceedings shall be pending or threatened
which could or would cause the redesignation or other modification of the
zoning classification of, or of any building code requirements applicable to
the Property or any portion thereof.

             e.     Title Company shall be irrevocably and unconditionally
committed to issue to Purchaser the Title Policy as described in Subparagraph
3(a) above.

        The Conditions Precedent are intended solely for the benefit of
Purchaser.  Subject to the provisions of Paragraph 7(b) below, if any of the
Conditions Precedent is not satisfied, Purchaser shall have the right in its
sole discretion either to waive in writing such Condition Precedent without
reduction in the Purchase Price and proceed with the purchase or terminate this
Agreement, in which event the Deposit shall be returned to Purchaser and the
parties shall be released from all obligations hereunder.

        In the event that Purchaser consummates the Closing hereunder, Purchaser
shall be deemed to have waived any and all unsatisfied conditions precedent.

7.     Remedies.

        a.    In the event the sale of the Property is not consummated because
of the failure of any condition or any other reason except a default under this
Agreement or any of the Other Agreements (as defined below) on the part of
Purchaser, the Deposit plus interest accrued thereon shall immediately be
returned to Purchaser.  If said sale is not consummated because of a default
under this Agreement or under any of the Other Agreements on the part of
Purchaser, the Deposit (but not the interest accrued thereon) shall be paid to
and retained by Seller as liquidated damages.  The parties have agreed that
Seller's actual damages, in the event of a default by Purchaser, would be
extremely difficult or impracticable to determine.  THEREFORE, BY PLACING THEIR
INITIALS BELOW, THE PARTIES ACKNOWLEDGE THAT THE DEPOSIT (AS WELL AS THE
DEPOSIT UNDER EACH OF THE OTHER AGREEMENTS) HAS BEEN AGREED UPON, AFTER
NEGOTIATION, AS THE PARTIES' REASONABLE ESTIMATE OF SELLER'S DAMAGES AND AS
SELLER'S EXCLUSIVE REMEDY AGAINST PURCHASER, AT LAW OR IN EQUITY, IN THE EVENT
OF A DEFAULT UNDER THIS AGREEMENT OR UNDER ANY OF THE OTHER AGREEMENTS ON THE
PART OF PURCHASER.  NOTWITHSTANDING THE FOREGOING PROVISIONS OF THIS PARAGRAPH
7(a), THIS



7
<PAGE>   8
PARAGRAPH 7(a) SHALL NOT LIMIT ANY RECOVERY BY SELLER PURSUANT TO THE
PROVISIONS OF PARAGRAPHS 13, 17(b), 17(h), AND 17(l) BELOW OR PURSUANT TO THE
PROVISIONS OF PARAGRAPHS 13, 17(b), 17(h), AND 17(l) OF ANY OF THE OTHER
AGREEMENTS.

              INITIALS:    Seller _______        Purchaser _______

        b.    In the event the sale of the Property is not consummated because
of a material default under this Agreement on the part of Seller or a material
default under any of the Other Agreements on the part of the "Seller"
thereunder, which default is not cured within three (3) business days after
receipt of written notice from Purchaser, or if a Condition Precedent cannot be
fulfilled because Seller frustrated such fulfillment by some willful act,
Purchaser may elect, as its sole and exclusive remedy hereunder, to either (1)
terminate this Agreement by delivery of notice of termination to Seller,
whereupon (A) the Deposit (as well as the Deposit under each of the Other
Agreements) plus interest accrued thereon shall be immediately returned to
Purchaser, and (B) Seller shall pay to Purchaser any title, escrow, legal and
inspection fees incurred by Purchaser and any other expenses incurred by
Purchaser in connection with the negotiation of this Agreement and the Other
Agreements and Purchaser's pursuit of the transactions contemplated hereunder
and under the Other Agreements and the performance of its due diligence review
of the Property and the "Property" described in the Other Agreements,
including, without limitation, environmental and engineering consultants' fees
and expenses and legal fees, and neither party shall have any further rights or
obligations hereunder, or (2) continue this Agreement pending Purchaser's
action for specific performance.

8.     Closing and Escrow.

        a.    Upon mutual execution of this Agreement, the parties hereto shall
deposit an executed counterpart of this Agreement with Title Company and this
Agreement shall serve as instructions to Title Company for consummation of the
purchase and sale contemplated hereby.  Seller and Purchaser agree to execute
such additional escrow instructions as may be appropriate to enable the escrow
holder to comply with the terms of this Agreement; provided, however, that in
the event of any conflict between the provisions of this Agreement and any
supplementary escrow instructions, the terms of this Agreement shall control.

        b.    The parties shall conduct an escrow Closing pursuant to this
Paragraph 8 on or before September 4, 1997 or on such other date as Purchaser
and Seller may agree in their sole and absolute discretion (the "Closing
Date"), provided, however, that Purchaser shall have the right to extend the
Closing Date on one or more occasions for up to thirty (30) days in the
aggregate so long as Purchaser (i) delivers written notice to Seller not less
than ten (10) business days prior to the then scheduled Closing Date, (ii)
deposits an





8


<PAGE>   9



additional One Hundred Ten Thousand Dollars ($110,000.00) (the "Extension
Deposit") in escrow with Title Company, and (iii) similarly extends the
"Closing Date" under each of the Other Agreements and deposits with Title
Company the "Extension Deposits" thereunder, and Seller shall have the right to
extend the Closing Date with respect to affected Constituent Parcels for up to
sixty (60) days as set forth in Paragraphs 6(c) and 11(b) hereof.  Upon deposit
with Title Company, the Extension Deposit shall be non-refundable, except to
the extent that this Agreement terminates as a result of a Seller default or
the failure of a condition to Closing for the benefit of Purchaser.

        c.    At or before the Closing, Seller shall deliver to Purchaser the
following:

              i.     the duly executed (and where appropriate acknowledged)
Deed, Bill of Sale, Assignment of Intangible Property and Assignment of Leases;

              ii.    duly executed estoppel certificates as required pursuant
to Subparagraph 8(b) above;

              iii.   originals of all Leases, Assumed Contracts, and building
permits, certificates of occupancy and plans and specifications for the
Improvements and all tenant-occupied space included within the Improvements to
the extent in Seller's possession or reasonable control;

              iv.    notices to the Tenants in form satisfactory to Purchaser,
duly executed by Seller;

              v.     a "FIRPTA Affidavit" pursuant to Section 1445 (b)(2) of
the Internal Revenue Code, duly executed by Seller;

              vi.    such resolutions, authorizations, bylaws or other
corporate and/or partnership documents or agreements relating to Seller as
shall be required by the Title Company;

              vii.   the certificate certifying as to Seller's representations
and warranties as required by Subparagraph 6(c) above;

              viii.  keys to all locks located in or about any portion of the
Property and all personal property described in the Bills of Sale to the extent
in Seller's possession or reasonable control; and

              ix.    any other customary and/or reasonable closing documents
requested by the Title Company.

Purchaser may waive compliance on Seller's part under any of the foregoing
items by an instrument in writing.

        d.    At or before the Closing, Purchaser shall deliver to Seller the
following:


9
<PAGE>   10
              i.     the duly executed Assignment of Leases and Assignment of
Intangible Property;

              ii.    such resolutions, authorizations, bylaws or other

              iii.   any other customary and/or reasonable closing documents
requested by the Title Company;

              iv.    in sufficient time to permit an 8:00 a.m. (Dallas time)
Closing, the balance of the Purchase Price in cash or other immediately
available funds, subject to prorations and adjustments as set forth herein.

        e.    Seller and Purchaser shall each deposit such other instruments as
are reasonably required by the escrow holder or otherwise required to close the
escrow and consummate the acquisition of the Property in accordance with the
terms hereof.  Seller and Purchaser hereby designate Title Company as the
"Reporting Person" for the transaction pursuant to Section 6045(e) of the
Internal Revenue Code and the regulations promulgated thereunder and agree to
execute such documentation as is reasonably necessary to effectuate such
designation.

        f.    The following are to be apportioned as of the Closing Date, as
follows:

              i.     RENT.  Rent for the current month under the Leases shall
be apportioned as of the Closing Date, regardless of whether or not such rent
has been paid to Seller.  With respect to any rent arrearages arising under the
Leases, after Closing Purchaser shall pay on or before the 15th day of each
calendar month to Seller any rent actually collected during the preceding month
that is applicable to the period preceding the Closing Date; provided, however,
that all rent collected by Purchaser shall be applied first to all unpaid rent
accruing after the Closing Date, and then to unpaid rent accruing prior to the
Closing Date.  Purchaser shall use reasonable efforts for a period of six (6)
months after Closing to recover rent arrearages, provided that Purchaser shall
not be obligated to sue any Tenant, evict any Tenant or institute any other
legal or quasi-legal proceeding against any Tenant.  Seller shall not be
permitted to take any steps to recover any rent arrearages after Closing,
provided that Seller shall have the right to commence suit against a Tenant to
recover rent arrearages for a period of six (6) months after the Closing and
prosecute such suit to completion and Seller shall have the right to sue a
Tenant at any time after such Tenant's Lease has expired or otherwise
terminates, provided that in no event shall Seller have the right to bring
either an unlawful detainer action or seek recourse to a Tenant's security
deposit transferred to Purchaser.

              ii.    LEASING COSTS; TENANT INDUCEMENTS.  Seller shall pay all
leasing commissions and tenant improvement costs that arise in connection with
any Lease executed on or before the Contract Date.  With respect to any new
Lease or Lease





10
<PAGE>   11
extension or expansion entered into by Seller between the Contract Date and the
Closing Date and approved by Purchaser pursuant to the terms of Paragraph 15(a)
below, in the event that Seller incurs or pays any costs or expenses for
leasing commissions and/or tenant allowances or improvements and/or free rent
(collectively, "New Leasing Costs") in connection with any such new Lease or
such extension or expansion in excess of the gross rental (including base rent,
additional rent and pass-throughs) (collectively, "New Leasing Revenue")
received by Seller with respect to such new Lease or such extension, Seller
shall be entitled to a credit at the Closing for the difference between the New
Leasing Costs and the New Leasing Revenue.  With respect to any free rent
applicable to the period after the Closing that arises under any new Lease or
Lease extension or expansion entered into by Seller between the Contract Date
and the Closing Date and approved by Purchaser pursuant to the terms of
Paragraph 15(a) below, such free rent shall be prorated between Seller and
Purchaser based on the number of months (or fractional months) in such new
Lease or such extension or expansion that are prior to the Closing Date and the
number of such months (or fractional months) that are after the Closing Date.

              iii.   SECURITY DEPOSITS; PREPAID RENT.  Purchaser shall be
entitled to a credit against the Purchase Price for the total sum of all
security deposits (and interest earned thereon) that are required to be
returned to the Tenants under the terms of the respective Leases.
Additionally, Purchaser shall be entitled to a credit against the Purchase
Price for the total sum of all free rent, operating expense abatements, or
other unexpired concessions under any Leases executed prior to the Contract
Date to the extent they apply to any period after the Closing.

              iv.    OTHER TENANT CHARGES.  For all items subject to proration
for which the landlord receives reimbursement from the tenants as common area
maintenance charges ("CAM Charges"), it is acknowledged that Seller has prepaid
certain CAM Charges and already received reimbursement on account of certain
estimated CAM Charges for the period prior to Closing and Purchaser will
similarly make certain payments and receive reimbursements on account of CAM
Charges for the period after Closing.  Seller shall be responsible for
collection of all estimated CAM Charges, including all delinquent amounts,
payable by the tenants prior to Closing, and Purchaser shall be responsible for
collection of all estimated CAM Charges, including delinquent amounts, payable
by the tenants after Closing.  Consistent with the foregoing sentence,
Purchaser and Seller shall prorate the expense items which are subject to
reimbursement pursuant to the CAM Charges in such a way that Seller shall be
responsible for the payment of all costs and expenses which are intended to be
reimbursed by such CAM Charges for the period prior to Closing and Purchaser
shall be responsible for all such costs and expenses after Closing.  At the end
of the fiscal year


11
<PAGE>   12
applicable to the CAM Charges described in the preceding sentences of this
Section, to the extent that the landlord has received excess CAM Charges and is
obligated to reimburse to the tenants any portion of the excess CAM charges
collected by Seller, Seller shall, within ten (10) days of written demand
therefor, reimburse to Purchaser the portion of such excess CAM Charges which
have been paid to and retained by Seller.  In the event that at the end of the
fiscal year applicable to such CAM Charges, tenants on the Property are
obligated to pay to the landlord any sums on account of an underpayment of CAM
Charges, Purchaser shall pay to Seller immediately upon receipt thereof
Seller's prorata share of such reimbursement by the tenants.  Purchaser shall
deliver to Seller at the same time that such notices are delivered to the
tenants any accounting or reconciliation of the CAM Charges for the fiscal year
in which the Closing occurs.

              v.     UTILITY CHARGES.  Seller shall be responsible for the cost
of all utilities used prior to the Closing Date, except to the extent such
utility charges are billed to and paid by tenants directly.

              vi.    OTHER APPORTIONMENTS; CLOSING COSTS.  Amounts payable
under the Assumed Contracts, annual or periodic permit and/or inspection fees
(calculated on the basis of the period covered), and liability for other
Property operation and maintenance expenses and other recurring costs shall be
apportioned as of the Closing Date.  Seller shall pay all transfer taxes and
sales tax (if any) on the Personal Property.  Seller shall pay the premium for
the Title Policy, provided that Purchaser shall pay the cost of the
Endorsements.  Purchaser acknowledges that if title to the Property and the
"Property" described and defined in the Other Agreements is taken in the name
of the same entity or entities, and unless business reasons (e.g. financing
requirements) dictate otherwise as determined by Purchaser in its good faith
discretion, Purchaser shall obtain one title policy covering both the Property
and the "Property" described and defined in the Other Agreements.  Seller and
Purchaser shall each pay fifty percent (50%) of all escrow and recording and
notary fees.  Seller shall be responsible for all costs incurred in connection
with the prepayment or satisfaction of any loan secured by the Property,
including, without limitation, any prepayment fees, penalties or charges.  All
other costs and charges of the escrow for the sale not otherwise provided for
in this Subparagraph 7(f)(vi) or elsewhere in this Agreement shall be allocated
in accordance with the applicable closing customs for Dallas County, Texas.

              vii.   REAL ESTATE TAXES AND SPECIAL ASSESSMENTS.  General real
estate taxes payable for 1996 and all prior years (including subsequent taxes
and assessments for prior years due to change in land usage or ownership) shall
be paid by Seller.  General real estate taxes payable for 1997 shall be
prorated by Seller and Purchaser as of the Closing Date.  If the amount of
general real estate taxes for 1997 cannot be determined on the Closing Date,
Seller shall deposit with the Title Company, from the Purchase Price, an amount
equal to Seller's proportionate share of the 1997 taxes based upon the most
current estimate of such taxes, assuming for estimating purposes that the
Property shall be fully assessed.  Such deposit shall be held in escrow and all
interest earnings on such deposit shall be paid to Seller.  The Title Company
shall retain such deposit to pay Seller's share of the actual general real
estate taxes payable for 1997, paying any excess over to Seller.  Seller shall
pay any deficiency, when such general real estate taxes are known.


12
<PAGE>   13
              viii.  PRELIMINARY CLOSING ADJUSTMENT.  Seller and Purchaser
shall jointly prepare a preliminary Closing adjustment on the basis of the
Leases and other sources of income and expenses, and shall deliver such
computation to Title Company not less than 10 days prior to Closing.

              ix.    POST-CLOSING RECONCILIATION.  If any of the aforesaid
prorations cannot be calculated accurately on the Closing Date, then they shall
be calculated as soon after the Closing Date as feasible.  Either party owing
the other party a sum of money based on such subsequent proration(s) shall
promptly pay said sum to the other party, together with interest thereon at the
rate of the lesser of (A) two percent (2%) over the average "prime rate" (as
announced from time to time in the Wall Street Journal) per annum or (B) the
highest legally permitted rate, from the Closing Date to the date of payment if
payment is not made within ten (10) days after delivery of a bill therefor.

       SURVIVAL.  The provisions of this Subparagraph 8(f) shall survive the
Closing.

        l.    No brokerage or similar fee is due or unpaid by Seller with

arising under any Lease.

Except as set forth in this Agreement or in any document executed pursuant to
or in connection with this Agreement, the parties hereto acknowledge and agree
that the sale of the Property to Purchaser is made on an "AS-IS, WHERE-IS" and
"WITH ALL FAULTS" basis, and Seller makes no warranty or representation,
express or implied, as to merchantability, suitability or fitness for a
particular purpose, the state of repair of the Property or the physical
condition thereof.  The parties further agree, however, that this paragraph
does not affect an assumption of any liability by Purchaser and that this
paragraph shall not be construed as to waive any rights of contribution or
indemnity or otherwise affect the liabilities of the parties to each other or
to third parties under any environmental law, including CERCLA.  The provisions
of this paragraph shall survive the Closing and the delivery and recordation of
the Deed.

The representations and warranties set forth in this Paragraph 9 shall survive
the Closing for the period set forth in Paragraph 17(e) below.

properties similar in type and character to the Property.

The representations and warranties set forth in this Paragraph 10 shall survive
the Closing for the period set forth in Paragraph 17(e) below.

11.    Other Agreements.

        a.    Notwithstanding anything to the contrary in this Agreement, but
subject to the provisions of Paragraph 11(b) below, it shall be a condition
precedent to both Purchaser's obligation to purchase the Property hereunder and
to Seller's obligation to sell the Property hereunder that the "Closing" under
and as defined in each of those three other Purchase Agreements dated as of
even date herewith and identified on Schedule 3 attached hereto (the "Other
Agreements") occurs concurrently with the Closing hereunder.  The parties
acknowledge and agree that a default by Seller under this Agreement shall be
deemed a default of each of the "Sellers" under each of the Other Agreements
and that a default by a "Seller" under any of the Other Agreements shall be
deemed a default by Seller hereunder.  The parties further acknowledge and
agree that a default by Purchaser under this Agreement shall be deemed a
default of each of the "Purchasers" under each of the Other Agreements and that
a default by a "Purchaser" under any of the Other Agreements shall be deemed a
default by Purchaser hereunder.

        b.     Notwithstanding anything to the contrary provided in Paragraph
11(a) above or elsewhere in this Agreement or any Other Agreement, in the event
that (i) Purchaser discovers during the Due Diligence Period that a Constituent
Parcel (as defined below) is in material violation of any Environmental Law
(but only if Seller fails to cure such violation prior to the Closing Date, as
such may be extended pursuant to this Paragraph 11(b), and Seller is unwilling
to give Purchaser a credit at Closing in such amount as the parties agree upon
will compensate Purchaser for such matter, it being acknowledged by the parties
hereto that Seller shall not be obligated hereunder to elect to cure any such
violation or offer to give Purchaser such a credit), (ii) Purchaser discovers
during the Due Diligence Period that there is a material defect in title that
adversely affects the marketability or financability of the Constituent Parcel
(but only if Seller fails to remedy such defect prior to the Closing Date, as
such may be extended pursuant to this Paragraph 11(b), and Seller is unwilling
to give Purchaser a credit at Closing in such amount as the parties agree upon
will compensate Purchaser for such matter, it being acknowledged by the parties
hereto that Seller shall not be obligated hereunder to elect to remedy any such
defect or offer to give Purchaser such a credit), (iii) Purchaser determines
during the Due Diligence Period that the net operating income derived from the
Property and the "Property" described and defined in the Other Agreements
differs in





16


<PAGE>   17



any material respect in the aggregate from that set forth in any materials
delivered to Purchaser by Seller or its agents prior to Purchaser's execution
of this Agreement or on the Rent Roll (as defined below) and one-third (() or
more of such discrepancy is attributable to any Constituent Parcel (but only to
the extent Seller is unwilling to give Purchaser a credit at Closing in an
amount equal to such loss of income, capitalized at the same rate as that
reflected by the Purchase Price, it being acknowledged by the parties hereto
that Seller shall not be obligated hereunder to offer to give Purchaser such a
credit), (iv) any of Seller's representations and warranties is not true and
correct in all material respects at Closing with respect to a Constituent
Parcel, (v) Purchaser discovers during the Due Diligence Period that there is a
material defect in the physical condition of a Constituent Parcel as disclosed
in an independent third party structural or physical report obtained by
Purchaser (but only if Seller fails to repair all such physical conditions
prior to the Closing Date, as such may be extended pursuant to this Paragraph
11(b), and Seller is unwilling to give Purchaser a credit at Closing in such
amount as the parties agree upon will compensate Purchaser for such matter, it
being acknowledged by the parties hereto that Seller shall not be obligated
hereunder to elect to repair such conditions or offer to give Purchaser such a
credit), or (vi) Purchaser elects to terminate this Agreement as to a
Constituent Parcel pursuant to Paragraph 12 below, Purchaser shall have the
right to terminate this Agreement as to such affected Constituent Parcels only
(each such Constituent Parcel being referred to herein as a "Removed Parcel"),
in which event this Agreement shall be amended to delete all references to the
Removed Parcel(s), the Purchase Price shall be reduced by the amount allocated
to the Removed Parcel(s) as set forth on Schedule 4 attached hereto, and this
Agreement and the Other Agreements shall otherwise remain in full force and
effect; provided, however, that with respect to the circumstances described in
clauses (i), (ii), (iii) and (v) above, Purchaser's right of termination shall
be conditioned upon Purchaser's informing Seller in writing prior to the end of
the Due Diligence Period that Purchaser will terminate this Agreement as to
such affected Constituent Parcel if such matter is not cured or remedied or
Purchaser is not otherwise compensated, as applicable, prior to the Closing.
Seller shall have the right to extend the Closing Date with respect to any
affected Parcel for up to sixty (60) days to remedy or cure any such
objectionable matter, provided that Seller (i) delivers written notice to
Purchaser within five (5) days after the end of the Due Diligence Period, which
notice shall state that Seller is electing to extend the Closing Date and that
Seller will use all commercially reasonable efforts to cure or remedy such
matter, and (ii) thereafter diligently proceeds to attempt to cure or remedy
such matter.  The sixty (60) day period set forth in the immediately preceding
sentence shall run concurrent with the sixty (60) day period set forth in
Paragraph 6(c) above.

        c.    Notwithstanding anything to the contrary provided in Paragraph
11(a) above or elsewhere in this Agreement or any Other Agreement, in the event
that the Removed Parcel(s) constitute(s) the entire Property, Purchaser shall
have the right to terminate this Agreement in its entirety, but elect to keep
the Other Agreements in full force and effect.



17
<PAGE>   18
        d.    As used herein, the term "Constituent Parcel" shall mean one of
the buildings identified on Schedule 1 attached hereto, together with the Land
and all other portions of the Property properly allocable thereto.

12.    Risk of Loss.

        a.    Purchaser shall be bound to purchase the Property for the full
Purchase Price as required by the terms hereof, without regard to the
occurrence or effect of any damage to the Property or destruction of any
improvements thereon or condemnation of any portion of the Property, provided
that (i) the cost to repair any such damage or destruction to a Constituent
Parcel, or the diminution in the value of the remaining Property as a result of
a partial condemnation, does not exceed $250,000 (and the cost to repair all
such damage or destruction to, or the diminution in value of, the Property and
the "Property" described and defined in the Other Agreements, in the aggregate,
does not exceed $1,000,000), and (ii) upon the Closing, there shall be a credit
against the Purchase Price due hereunder equal to the amount of any insurance
proceeds or condemnation awards collected by Seller as a result of any such
damage or destruction or condemnation, less any sums reasonably expended by
Seller toward the restoration or repair of the affected Property, and, if the
proceeds or awards have not been collected as of the Closing, then such
proceeds or awards shall be assigned to Purchaser.

        b.    If the amount of the damage or destruction or condemnation as
specified in Paragraph 12(a) above exceeds $250,000 with respect to any
Constituent Parcel, then Purchaser may, at its option to be exercised within
twenty (20) days of Seller's written notice of the occurrence of the damage or
destruction or the commencement of condemnation proceedings, either terminate
this Agreement in its entirety or solely with respect to such Constituent
Parcel or consummate the purchase for the full Purchase Price as required by
the terms hereof.  Similarly, if the amount of the damage or destruction or
condemnation as specified in Paragraph 12(a) above exceeds $1,000,000 with
respect to the Property and the "Property" described and defined in the Other
Agreements, in the aggregate, then Purchaser may, at its option to be exercised
within twenty (20) days of Seller's written notice of the occurrence of the
damage or destruction or the commencement of condemnation proceedings, either
terminate this Agreement in its entirety or consummate the purchase for the
full Purchase Price as required by the terms hereof.  If Purchaser elects to
terminate this Agreement in its entirety or fails to give Seller written notice
within such 20-day period that Purchaser will proceed with the purchase, then
the Deposit shall be immediately returned to Purchaser and neither party shall
have any further rights or obligations hereunder, except to the extent
expressly otherwise set forth herein.  If Purchaser elects to terminate this
Agreement solely with respect to such affected Constituent Parcel, the
provisions of Paragraph 11(b) above shall control.  If Purchaser elects to
proceed with the purchase as to the entire Property, then upon the Closing,
there shall be a credit against the Purchase Price due hereunder equal to the
amount of any insurance proceeds or condemnation awards collected by Seller as
a result of any such damage or destruction or condemnation, less any sums
reasonably





18


<PAGE>   19



expended by Seller toward the restoration or repair of the affected Property,
and, if the proceeds or awards have not been collected as of the Closing, then
such proceeds or awards shall be assigned to Purchaser.

        c.    In the event that Purchaser is required to or elects to purchase
the entire Property following any damage or destruction or condemnation of the
Property pursuant to Paragraph 12(a) or (b) above, Seller shall also provide
Purchaser with a credit against the Purchase Price in an amount equal to any
deductible or uninsured amount; provided, however, in no event shall Seller be
required to provide Purchaser with a credit pursuant to this Paragraph 12(c) in
an amount that exceeds $250,000 with respect to any Constituent Parcel or that
exceeds $1,000,000 with respect to the Property and the "Property" described
and defined in the Other Agreements, in the aggregate.  If it is determined
that the deductible or uninsured amount is greater than $250,000 (or
$1,000,000, as applicable), Seller shall notify Purchaser in writing as soon as
reasonably possible following such determination whether or nor Seller is
willing to provide Purchaser with a credit against the Purchase Price in the
full amount of such deductible or uninsured amount.  In the event that Seller
is unwilling to provide Purchaser with a credit in such full amount, Purchaser
shall have the right to terminate this Agreement by delivering written notice
to Seller within twenty (20) days after Purchaser's receipt of such notice from
Seller.  If Purchaser elects to terminate this Agreement or fails to give
Seller written notice within such twenty (20) day period that Purchaser will
proceed with the purchase, the Deposit shall be immediately returned to
Purchaser and neither party shall have any further obligations hereunder,
except to the extent expressly otherwise set forth herein.

13.    Possession.

       Possession of the Property shall be delivered to Purchaser on the
Closing Date subject only to the rights of Tenants under the Leases, provided,
however, that prior to the Closing Date Seller shall afford authorized
representatives of Purchaser (as well as any actual or prospective lender to
Purchaser) reasonable access to the Property, upon 24 hours notice, for
purposes of satisfying Purchaser (and such lender) with respect to the
representations, warranties and covenants of Seller contained herein and with
respect to satisfaction of any Diligence Period Condition or any Condition
Precedent (including, without limitation, the Condition Precedent set forth in
Paragraph 6(d) above) and for the purpose of conducting Tenant interviews,
provided that prior to entering the Property Purchaser shall (i) obtain
comprehensive general liability insurance in an amount not less than $1,000,000
naming Seller as an additional insured and (ii) provide a copy of such policy
or a certificate evidencing such coverage to Seller.  Purchaser hereby agrees
to indemnify and hold Seller harmless from any damage or injury to persons or
property caused by Purchaser or its authorized representatives during their
entry and investigations prior to the Closing, provided the foregoing shall not
require Purchaser to indemnify Seller or any other person with respect to any
conditions that are discovered by Purchaser as opposed to being first caused by
Purchaser.  If this Agreement is terminated, Purchaser shall repair the damage
caused by Purchaser's entry and investigations, provided the


19
<PAGE>   20
foregoing shall not require Purchaser to repair or remediate any conditions
that are discovered by Purchaser as opposed to being first caused by Purchaser.
The foregoing indemnity shall survive the termination of this Agreement or the
Closing, as applicable.

14.  Maintenance of the Property; Miscellaneous Covenants.

       Between the Contract Date and the Closing, Seller shall perform all of
the landlord's obligations under the Leases and shall otherwise operate and
maintain the Property in the same manner as before the making of this
Agreement, as if Seller were retaining the Property.  Seller shall promptly
notify Purchaser of any condemnation, environmental, zoning or other land-use
regulation proceedings of which Seller becomes aware, as well as any notices of
violations of any Laws relating to the Property of which Seller becomes aware
and any litigation of which Seller becomes aware that arises out of the
ownership of the Property or that might detrimentally affect the value or the
use or operation of the Property or the ability of Seller to perform its
obligations hereunder.  Following the Contract Date, Seller shall continue to
prepare Operating Statements (as defined in Exhibit G hereto) for the Property
as to all time periods subsequent to the dates of the Operating Statements
delivered to Purchaser as part of the Delivery Items and prior to the Closing
Date, which Operating Statements shall be delivered to Purchaser within a
reasonable period of time following the end of the period with respect to which
such Operating Statements are prepared, even if prepared after Closing.

Seller's sole cost and expense, all policies of insurance currently in effect
with respect to the Property (or comparable replacements thereof).

15.  Purchaser's Consent to New Contracts Affecting the Property; Termination
       of Existing Contracts.

       a.     Seller shall not, after the Contract Date, enter into any Lease
or contract, or any amendment thereof, or permit any Tenant to enter into any
sublease, assignment or agreement pertaining to the Property, or waive any
rights of Seller under any contract or Lease, without in each case obtaining
Purchaser's prior written consent thereto, which consent in the case of any
Lease shall include approval of the financial condition of the proposed tenant,
the configuration of the space to be leased, and the terms of such Lease
(including, without limitation, the rent and any concessions provided under
such proposed Lease), and which consent shall not be unreasonably withheld by
Purchaser.  Seller shall be entitled, without the consent of Purchaser, to
enter into, amend or otherwise deal with service contracts and similar
agreements that are not Assumed Contracts in the ordinary course of business
that are terminable on not more than thirty (30) days' prior notice and which
shall not be binding on Purchaser after the Closing Date.  Seller shall deliver
to Purchaser, together with any request for approval of a new Lease, a copy of
the proposed Lease, a description of the proposed Tenant and its proposed use
of the premises and whatever financial information on the proposed Tenant
Seller has received, as well as any additional information reasonably requested
by

Purchaser (including, without limitation, if applicable, an environmental
questionnaire).  Notwithstanding anything to the contrary provided in this
Subparagraph 15(a), if Purchaser fails to respond in writing with respect to
any such new Lease or other action requiring Purchaser's consent under this
Subparagraph 15(a) within five (5) business days after Purchaser's receipt of
such request and information, Purchaser shall be deemed to have approved such
new Lease or other action.

        b.    Seller shall terminate prior to the Closing, at no cost or
expense to Purchaser, any and all management agreements, service contracts or
similar agreements affecting the Property that are not Assumed Contracts.

        c.    Seller shall not, after the Contract Date, create any new
encumbrance or lien affecting the Property other than liens and encumbrances
(i) that are reasonably capable of being discharged prior to the Closing and
(ii) that in fact will be and are discharged prior to the Closing.

16.    Cooperation with Purchaser.

       Seller shall cooperate and do all acts as may be reasonably required or
requested by Purchaser with regard to the fulfillment of any Condition
Precedent including execution of any documents, applications or permits
reasonably requested by Purchaser and, to the extent requested by Purchaser,
agrees to cooperate with Purchaser's efforts to obtain subordination, non-
disturbance and attornment agreements from the Tenants.  Seller hereby
authorizes Purchaser and its agents to make all inquiries with and applications
to any third party, including any governmental authority, as Purchaser may
reasonably require to complete its due diligence.

17.    Miscellaneous.

        a.    NOTICES.  Any notice, consent or approval required or permitted

        b.    BROKERS AND FINDERS.  Neither party has had any contact or
dealings regarding the Property, or any communication in connection with the
subject matter of this transaction, through any real estate broker or other
person who can claim a right to a commission or finder's fee in connection with
the sale contemplated herein, except for Cushman & Wakefield of Texas, Inc.
("Broker"), whose commission shall be paid by Seller pursuant to the terms of a
separate agreement between Seller and Broker.  In the event that any other
broker or finder makes a claim for a commission or finder's fee based upon any
contact, dealings or communication, the party whose conduct is the basis for
the broker or finder making its claim shall indemnify, defend and hold harmless
the other party against and from any commission, fee, liability, damage, cost
and expense, including without limitation attorneys' fees, arising out of or
resulting from any such claim. The provisions of this paragraph shall survive
the Closing.

        c.    SUCCESSORS AND ASSIGNS.  This Agreement shall be binding upon,
and inure to the benefit of, the parties hereto and their respective
successors, heirs, administrators and assigns.  Notwithstanding the foregoing,
Purchaser shall not have the right, without the prior written approval of
Seller, to assign this Agreement in whole or in part, provided that Purchaser
may assign this Agreement upon notice to Seller (but without any requirement of
obtaining Seller's consent) in whole or in part to (i) one or more entities in
which Marc R. Brutten, Jay H. Shidler and/or James C. Reynolds, directly or
indirectly, has an ownership interest, and/or (ii) an entity controlled or
managed by, or otherwise affiliated with, Angelo Gordon & Co., provided that
such assignee(s) shall assume all of the obligations of Purchaser hereunder and
the foregoing shall not act as a release of the party originally designated as
Purchaser hereunder.  To the extent that any indemnity set





22


<PAGE>   23
forth in this Agreement is made for the benefit of Purchaser or Seller, the
term "Purchaser" or "Seller", as applicable, as it pertains to an indemnified
party only, shall include the managers, members, investors, affiliates,
lenders, officers, directors, shareholders, partners, trustees, beneficiaries,
agents and employees of such party and their respective heirs, representatives,
successors and assigns.

        d.    AMENDMENTS.  Except as otherwise provided herein, this Agreement
may be amended or modified only by a written instrument executed by Seller and
Purchaser.

        e.    CONTINUATION AND SURVIVAL OF REPRESENTATIONS AND WARRANTIES, ETC.
All representations and warranties by the respective parties contained herein
or made in writing pursuant to this Agreement are intended to and shall remain
true and correct as of the time of Closing, shall be deemed to be material,
and, together with all conditions, covenants and indemnities made by the
respective parties contained herein or made in writing pursuant to this
Agreement, shall survive the execution and delivery of this Agreement and the
Closing for a period of 12 months, or, to the extent the context requires,
beyond any termination of this Agreement.  In the event that a claim is not
made with respect to a breach of a representation, warranty or covenant set
forth herein within such 12 month period, such claim shall be deemed waived.

        f.    GOVERNING LAW.  This Agreement shall be governed by and construed
in accordance with the laws of the State of Texas.

        g.    MERGER OF PRIOR AGREEMENTS.  This Agreement and the exhibits and
schedules hereto constitute the entire agreement between the parties and
supersede all prior agreements and understandings between the parties relating
to the subject matter hereof.

        h.    ENFORCEMENT.  If either party hereto fails to perform any of its
obligations under this Agreement or if a dispute arises between the parties
hereto concerning the meaning or interpretation of any provision of this
Agreement, then the defaulting party or the party not prevailing in such
dispute shall pay any and all costs and expenses incurred by the other party on
account of such default and/or in enforcing or establishing its rights
hereunder, including, without limitation, court costs and attorneys' fees and
disbursements.  Any such attorneys' fees and other expenses incurred by either
party in enforcing a judgment in its favor under this Agreement shall be
recoverable separately from and in addition to any other amount included in
such judgment, and such attorneys' fees obligation is intended to be severable
from the other provisions of this Agreement and to survive and not be merged
into any such judgment.

        i.    TIME OF THE ESSENCE.  Time is of the essence of this Agreement.

        j.    SEVERABILITY.  If any provision of this Agreement, or the
application thereof to any person, place, or circumstance, shall be held by a
court of competent jurisdiction to be invalid, unenforceable or void, the
remainder of this Agreement and such provisions as applied to other persons,
places and circumstances shall remain in full force and effect.

        k.    MARKETING.  During the term of this Agreement, Seller shall not
list the Property with any broker or otherwise solicit or make or accept any
offers to sell the Property, engage in any discussions or negotiations with any
third party with respect to the sale or other disposition of the Property, or
enter into any contracts or agreements (whether binding or not) regarding any
disposition of the Property.

        l.    CONFIDENTIALITY.  Each party agrees to maintain in confidence,
and not to disclose to any third party, the information contained in this
Agreement or pertaining to the sale contemplated hereby and the information and
data furnished or made available by Seller to Purchaser, its agents and
representatives in connection with Purchaser's investigation of the Property
and the transactions contemplated by the Agreement; provided, however, that
each party, its agents and representatives may disclose such information and
data (a) to such party's accountants, attorneys, prospective lenders,
accountants, partners, consultants and other advisors in connection with the
transactions contemplated by this Agreement (collectively "Representatives") to
the extent that such Representatives reasonably need to know (in Purchaser's or
Seller's reasonable discretion) such information and data in order to assist,
and perform services on behalf of, Purchaser or Seller; (b) to the extent
required by any applicable statute, law, regulation, governmental authority or
court order; and (c) in connection with any litigation that may arise between
the parties in connection with the transactions contemplated by this Agreement.
In the event of any conflict between the terms of this Section 17(l) and the
terms of the Confidentiality Agreement referenced in Section 17(g) above, the
terms of said Confidentiality Agreement shall control.  Each party shall
consult with the other party prior to making any press release or other
disclosure intended for general circulation regarding the transactions
contemplated hereunder.  In no event shall any such disclosure or press release
contain the purchase price.

        m.    SECTION 1031 EXCHANGE.  It is presently contemplated that
Purchaser and Seller may each desire to effectuate a tax-deferred exchange
(also known as a "1031" exchange) (an "Exchange") in connection with the
purchase and sale of the Property.  Purchaser and Seller hereby agree to
cooperate with each other in connection with one or more such Exchanges,
provided that:

              i.     All documents executed by a party in connection with the
Exchange shall be subject to the prior reasonable approval of that party and
shall recognize that that party is acting solely as an accommodating party to
such Exchange, shall have no liability with respect thereto, and is making no
representation or warranty that the transactions qualify as a tax-free exchange
under Section 1031 of the Internal Revenue Code or any applicable state or
local laws and shall have no liability whatsoever if any such transactions
fails to so qualify.

              ii.    Such Exchange shall not result in Purchaser or Seller
incurring any additional costs or liabilities.





24
<PAGE>   25

              iii.   In no event shall Purchaser or Seller be obligated to
acquire any property or otherwise be obligated to take title, or appear in the
records of title, to any property in connection with such Exchange.

              iv.    In no event shall Purchaser's or Seller's consummation of
such Exchange constitute a condition precedent to that party's obligations
under this Agreement, and Purchaser's or Seller's failure or inability to
consummate such Exchange for any reason or for no reason at all shall not be
deemed to excuse or release that party from its obligations under this
Agreement.

        n.    POST-CLOSING COOPERATION.  If it becomes reasonably necessary to
do so in order to comply with applicable securities laws or the rules or
regulations of the Securities and Exchange Commission, for a period of four (4)
years after the Closing Date, Purchaser and its agents shall have the right, at
Purchaser's sole cost and expense, to inspect and obtain copies of Seller's
books and records supporting the operation of the Property for the period of
three (3) full calendar years preceding the calendar year which includes the
Closing Date.  Purchaser shall give reasonable prior written notice to Seller
when Purchaser wishes to exercise its right to inspect such books and records.
Such inspection shall take place at the office of Seller during normal business
hours on a date and at a time reasonably convenient to Seller and Purchaser.
The provisions of this Paragraph 17(n) shall survive the Closing.

        o.    RETURN OF DOCUMENTS.  In the event that this Agreement
terminates, Purchaser shall return to Seller all due diligence materials and
all copies thereof delivered by Seller to Purchaser hereunder and, subject to
any restrictions on transferability set forth therein, shall deliver to Seller
copies of all reports generated by Purchaser's contractors, engineers and other
third party professional (non-legal) consultants, all of which reports shall be
delivered by Purchaser without any representation or warranty as to the
contents thereof.

                     SECOND AMENDMENT TO PURCHASE AGREEMENT

       THIS SECOND AMENDMENT TO PURCHASE AGREEMENT (this "Second Amendment"),
is made as of July 31, 1997, by and between SHIDLER WEST INVESTMENT
CORPORATION, a Delaware corporation ("Purchaser"), and MERIT VV 1995 INDUSTRIAL
PORTFOLIO LIMITED PARTNERSHIP, a Texas limited partnership ("Seller"), with
reference to the following facts:

       A.    Seller and Purchaser entered into that certain Purchase
Agreement, dated as of July 2, 1997, as amended by that certain First Amendment
to Purchase Agreement dated as of July 30, 1997 (collectively, the "Purchase
Agreement").  Each capitalized term used in this Second Amendment, but not
defined herein, shall have the meaning ascribed to it in the Purchase
Agreement.

       B.    Seller and Purchaser desire to amend the Purchase Agreement as
set forth in this Second Amendment.

       NOW, THEREFORE, the parties agree as follow:

       1.     Due Diligence Period.  Notwithstanding anything to the contrary
provided in the Purchase Agreement, the Due Diligence Period shall expire on

approve any title exceptions first disclosed to Purchaser subsequent to the end
of the Due Diligence Period.

Amendment, the provisions of the Purchase Agreement shall remain in full force.
If any

provision of this Second Amendment conflicts with any provision of the Purchase
Agreement, then the provisions of this Second Amendment shall prevail.

counterparts (including facsimile counterparts) which, when signed by all
parties, shall constitute a binding agreement.

                                                                     EXHIBIT 2.4


                               PURCHASE AGREEMENT

         This Agreement is made and entered into as of this 30th day of June,
1997, by and between SHIDLER WEST INVESTMENT CORPORATION, a Delaware
corporation ("Purchaser"), and MERIT VV LAND 1995 INDUSTRIAL PORTFOLIO LIMITED
PARTNERSHIP, a Texas limited partnership (Seller").

         In Consideration of the respective agreements hereinafter set forth,
Seller and Purchaser hereby agree as follows:

1.       Purchase and Sale.

         Seller agrees to sell and convey to Purchaser, and Purchaser agrees to
purchase from Seller, on the terms and conditions set forth in this Agreement,
the Property.  As used herein, the term the "Property" shall mean,
collectively: (a) the parcels of land described in Exhibit A attached hereto
(collectively, the "Land"), together with all rights, easements and interests
appurtenant thereto including, but not limited to, any streets or other public
ways adjacent to the Land and any development rights, water or mineral rights
owned by, or leased to, Seller; (b) all improvements located on the Land,
including, but not limited to, all buildings and other structures, systems, and
utilities associated with, and utilized by Seller in the ownership and
operation of such building(s) (all such improvements, together with such
building(s), being referred to herein as the "Improvements"), but excluding
improvements, if any, owned by tenants of such building(s); (c) all personal
property owned by Seller, located on or in the Land or Improvements, or used in
connection with the operation and maintenance of the Property (the "Personal
Property"), including, without limitation, all personal property listed on
Exhibit B attached hereto; (d) all building materials, supplies, hardware,
carpeting and other inventory maintained in connection with Seller's ownership
and operation of the Property (the "Inventory"); (e) all trademarks,
tradenames, and entitlements and other intangible property used or useful in
connection with the foregoing, including, without limitation, all of Seller's
right, title and interest in any and all warranties and guaranties relating to
the Property, but excluding all rights to use the name "Merit" (the "Intangible
Personal Property"); and (f) Seller's interest in all leases and other
agreements to occupy all or any portion of the Property that are in effect on
the Contract Date (defined below) or into which Seller enters prior to Closing
(defined below), but pursuant to the terms of this Agreement (as such may have
been amended, modified or supplemented, the "Leases").

2.       Purchase Price; Independent Contract Consideration.

         a.      The purchase price of the Property shall be Five Hundred
Thousand Dollars ($500,000.00) (the "Purchase Price").  The Purchase Price
shall be paid to Seller at Closing, plus or minus prorations and other
adjustments hereunder, in immediately available funds.

         b.      The Purchase Price shall be paid as follows:


1
<PAGE>   2
                 i.       Upon mutual execution of this Agreement, Purchaser
shall deliver to Commonwealth Land Title Company of Dallas ("Title Company") a
deposit in the amount of Fifty Thousand Dollars ($50,000.00) (the "Initial
Deposit; and, together with the Extension Deposit (as defined below), if
applicable, the "Deposit").  The Deposit shall be held in an interest-bearing
account and interest accruing thereon shall be held for the account of
Purchaser.  In the event the sale of the Property as contemplated hereunder is
consummated, the Deposit plus interest accrued thereon shall be delivered to
Seller at the Closing and credited against the Purchase Price.

                 ii.      Prior to or contemporaneous with the execution hereof
by Purchaser and Seller, Purchaser has paid to Seller One Hundred Dollars
($100.00) (the "Independent Contract Consideration"), which amount Seller and
Purchaser bargained for and agreed to as consideration for Seller's execution
and delivery of this Agreement.  The Independent Contract Consideration is
non-refundable and in addition to any other payment or deposit required by this
Agreement, and Seller shall retain the Independent Contract Consideration
notwithstanding any other provision of this Agreement to the contrary;
provided, however, that if the Closing shall occur hereunder, then the
Independent Contract Consideration shall be applied to the Purchase Price.

                 iii.     The balance of the Purchase Price shall be paid to
Seller at the closing of the purchase and sale contemplated hereunder (the
"Closing").

3.       Title to the Property.

         a.      At the Closing, Seller shall convey to Purchaser indefeasible
and insurable fee simple title to the Land and the Improvements, by one or more
duly executed and acknowledged special warranty deeds in the form attached
hereto as Exhibit C (collectively, the "Deed").  Evidence of delivery of
indefeasible and insurable fee simple title shall be the issuance by Title
Company to Purchaser of a Texas Owner's Policy of Title Insurance (Form T-1) in
the amount of the Purchase Price (the "Title Policy"), insuring fee simple
title to the Land and the Improvements in Purchaser, subject only to such
exceptions as Purchaser shall approve pursuant to Subparagraph 5(a) below (the
"Permitted Exceptions").  The Title Policy shall contain such special
endorsements as Purchaser may reasonably require, including, without
limitation, the amendment of the survey exception to read "shortages in area"
only (the "Endorsements").  The Title Company shall also provide for
reinsurance with direct access with such companies and in such amounts as
Purchaser shall reasonably request.

         b.      At the Closing, Seller shall transfer title to the Personal
Property and the Inventory by a bill of sale in the form attached hereto as
Exhibit D (the "Bill of Sale"), such title to be free of any liens,
encumbrances or interests, other than the Permitted Exceptions.

         c.      At the Closing, Seller shall transfer title to the Intangible
Personal Property by an assignment of service contracts, warranties and
guaranties and other





2
<PAGE>   3
intangible property in the form attached hereto as Exhibit E (the "Assignment
of Intangible Property") and shall transfer title to the Leases, if any, by an
assignment of leases in the form attached hereto as Exhibit F (the "Assignment
of Leases"), such title to be free of any liens, encumbrances or interests,
other than the Permitted Exceptions.

4.       Due Diligence and Time for Satisfaction of Conditions.

         Purchaser shall have the right to commence due diligence with respect
to the Property following the date on which this Agreement is fully executed by
the parties hereto (the "Contract Date") and the due diligence period ("Due
Diligence Period") shall expire on July 30, 1997, provided, however, in the
event that Seller fails to deliver to Purchaser any of the items identified on
Exhibit G attached hereto and identified with an asterisk (the "Delivery
Items") on or before the date that is five (5) days after the Contract Date,
the Due Diligence Period shall be extended with respect to such undelivered
Delivery Item only by one day for each day beyond such fifth (5th) day until
such Delivery Item is delivered to Purchaser.  In addition to the foregoing,
Seller shall, upon 24 hours notice, make available to Purchaser and its
employees, representatives, counsel and consultants access to all of its books,
records and files relating to the Property in Seller's possession or reasonable
control, including, without limitation, all of the items set form on said
Exhibit G other than the Delivery Items, and Seller agrees, to the extent
reasonably feasible, to allow Purchaser to make copies at Seller's office or
the property management office of such items as Purchaser reasonably requests.
As used in this Agreement, the term "reasonable control" mean those items in
the possession of Seller's agents or independent contractors under direct
contract with Seller or its affiliates, and the term "affiliate" means any
entity or person controlled by, controlling or under common control with a
named person or entity.

5.       Diligence Period Conditions.

         The following conditions are precedent to Purchaser's obligation to
purchase the Property and to deliver the Purchase Price (the "Diligence Period
Conditions"):

         a.      Purchaser's review and approval of title to the Property, as
follows.  Seller shall deliver to Purchaser at Seller's sole cost and expense,
within five (5) days after the Contract Date, the following:

                 i.       one or more current standard coverage preliminary
title reports on the Land, issued by Title Company, accompanied by copies of
all documents referred to in the reports (the "Preliminary Reports").  In the
event the Title Company issues any supplements to the Preliminary Reports
during the term of this Agreement, Purchaser shall have five (5) business days
following delivery of any such supplemental report to approve or disapprove in
writing of any exception contained therein and not disclosed in the Preliminary
Reports, or any prior supplement thereto;





3
<PAGE>   4
                 ii.      copies of all existing and proposed easements,
covenants, restrictions, agreements or other documents which affect title to

                 iv.      copies of the most recent property tax bills for the 
Property.

   Purchaser shall advise Seller, at least ten (10) days prior to the end of
the Due Diligence Period, what exceptions to title, if any, will be accepted by
Purchaser.  Seller shall have five (5) days after receipt of Purchaser's
objections to give Purchaser:  (i) notice that Seller shall use all reasonable
efforts to remove all disapproved exceptions from title on or before the
Closing Date; or (ii) notice that Seller elects not to cause such exceptions to
be removed.  If Seller gives Purchaser notice under clause (ii), Purchaser
shall have five (5) days to elect to proceed with the purchase or terminate
this Agreement.  If Purchaser shall fail to give Seller notice of its election
within said five (5) days, Purchaser shall be deemed to have elected to
terminate this Agreement.  If Seller gives notice under clause (i) above and
fails to remove all such disapproved exceptions prior to the Closing Date
despite using its reasonable efforts and Purchaser is unwilling to accept title
subject to such exception in its sole and absolute discretion, Purchaser shall
have the right to terminate this Agreement.  Notwithstanding anything to the
contrary provided herein, Seller shall be obligated to remove or endorse over
to the reasonable satisfaction of Purchaser prior to Closing all monetary liens
encumbering the Property (or any portion thereof) other than the lien of any
property taxes, not yet due or payable.

         b.      Purchaser's review and approval of the matters described in
Paragraph 4 above and each component thereof as Purchaser shall desire in its
sole and absolute discretion.  Such review shall include an examination for the
presence or absence of Hazardous Material (as defined in Subparagraph 8(j)
below).  Notwithstanding anything to the contrary contained herein, Purchaser
shall not engage in or otherwise conduct any additional environmental studies
or environmental testing or sampling of any kind with respect to the Property
or with respect to the soils or ground water, or other studies which would
require test boring or which testing would otherwise damage or disturb any
portion of the Property, without obtaining Seller's prior written consent
thereto, which consent shall not be unreasonably withheld, delayed or
conditioned.

         c.      Purchaser's review and approval, within the Due Diligence
Period, of a schedule (the "Schedule of Agreements") setting forth an exclusive
list of all of the service contracts and similar agreements affecting the
Property.  Prior to the end of the Due Diligence Period, Purchaser shall
deliver to Seller a list setting forth those service contracts and similar
agreements that shall be assigned to, and assumed by, Purchaser at the Closing
(the "Assumed Contracts").  Purchaser shall have the right, in its sole
discretion, to require the termination of any service contract or similar
agreement that is 





4

<PAGE>   5
not an Assumed Contract effective as of the Closing, provided that either (i) 
such contract or agreement is terminable by Seller without the payment of any 
fee or penalty and Purchaser provides to Seller adequate notice that Purchaser 
shall require the termination of such contract or agreement or (ii) the service
provider is an affiliate of Seller or Seller's general partner.

         Prior to the end of the Due Diligence Period, Purchaser shall deliver
written notice (the "Approval Notice") to Seller informing Seller whether or
not Purchaser has approved or waived all of the Diligence Period Conditions.
Notwithstanding anything in this Agreement to the contrary, Purchaser shall
have the right to terminate this Agreement at any time prior to the end of the
Due Diligence Period in its sole and absolute discretion and for any or for no
reason whatsoever.  If, by the end of the Due Diligence Period, Purchaser shall
not have delivered the Approval Notice to Seller approving or waiving all of
the Diligence Period Conditions, then this Agreement shall automatically
terminate, the Deposit shall be returned to Purchaser and the parties shall be
released from all obligations hereunder.

6.       Conditions to Closing.

   The following conditions are precedent to Purchaser's obligation to acquire
the Property and to deliver the Purchase Price (the "Conditions Precedent"):

         a.      This Agreement shall not have terminated pursuant to any other
provision hereof, including, without limitation, Paragraph 5 above.

         b.      INTENTIONALLY OMITTED.

         c.      All of Seller's representations and warranties contained in or
made pursuant to this Agreement shall have been true and correct when made and
shall be true and correct as of the Closing Date.  At the Closing Seller shall
deliver to Purchaser a certificate certifying that each of Seller's
representations and warranties contained in Paragraph 8 below are true and
correct as of the Closing Date.  In the event that Seller advises Purchaser
prior to the Closing that any of Seller's representations or warranties set
forth herein is not true and correct as a result of an event occurring after
the Contract Date that is beyond the control of Seller or Seller's employees,
partners, agents or contractors, then Purchaser's sole remedy shall be to
cancel and terminate this Agreement and receive the return of the Deposit or to
waive the condition precedent set forth in this Paragraph 6(c) with respect to
such representation or warranty and, in the event the Closing occurs, Purchaser
shall not be entitled to any reduction in the Purchase Price or recover damages
from Seller with respect to such representation or warranty.  Notwithstanding
anything to the contrary set forth above, in the event that Purchaser advises
Seller prior to the Closing that any of Seller's representations or warranties
set forth herein is not true and correct, Seller shall have the right to elect
to cure such untrue or incorrect representation or warranty prior to the
Closing, and in the event that Seller cures all such untrue or incorrect
representations and warranties prior to the Closing, the Condition Precedent
set forth in this Paragraph 6(c) shall be deemed satisfied.  Seller





5
<PAGE>   6
shall have the right to extend the Closing Date with respect to any affected
Constituent Parcel Constituent Parcel (as defined below) for up to sixty (60)
days to cure any such untrue or incorrect representations or warranties,
provided that Seller (i) delivers written notice to Purchaser within five (5)
days after Seller receives such notification from Purchaser, which notice shall
state that Seller is electing to extend the Closing Date and that Seller will
use all commercially reasonable efforts to cure such untrue or incorrect
representation or warranty, and (ii) thereafter diligently proceeds to attempt
to cure all such untrue or incorrect representations and warranties.  The sixty
(60) day period set forth in the immediately preceding sentence shall run
concurrent with the sixty (60) day period set forth in Paragraph 11(b) below.

         d.      The physical condition of the Property shall be substantially
the same on the day of Closing as on the date of Purchaser's execution of this
Agreement, reasonable wear and tear and loss by casualty excepted (subject to
the provisions of Paragraph 12 below), and, as of the day of Closing, there
shall be no litigation or administrative agency or other governmental
proceeding of any kind whatsoever, pending or threatened, which after Closing
would materially adversely affect the value of the Property or the ability of
Purchaser to operate the Property in the manner in which it is currently being
operated, and no proceedings shall be pending or threatened which could or
would cause the redesignation or other modification of the zoning
classification of, or of any building code requirements applicable to the
Property or any portion thereof.

         e.      Title Company shall be irrevocably and unconditionally
committed to issue to Purchaser the Title Policy as described in Subparagraph
3(a) above.

         The Conditions Precedent are intended solely for the benefit of
Purchaser.  Subject to the provisions of Paragraph 7(b) below, if any of the
Conditions Precedent is not satisfied, Purchaser shall have the right in its
sole discretion either to waive in writing such Condition Precedent without
reduction in the Purchase Price and proceed with the purchase or terminate this
Agreement, in which event the Deposit shall be returned to Purchaser and the
parties shall be released from all obligations hereunder.

         In the event that Purchaser consummates the Closing hereunder,
Purchaser shall be deemed to have waived any and all unsatisfied conditions
precedent.

7.       Remedies.

         a.      In the event the sale of the Property is not consummated
because of the failure of any condition or any other reason except a default
under this Agreement or any of the Other Agreements (as defined below) on the
part of Purchaser, the Deposit plus interest accrued thereon shall immediately
be returned to Purchaser.  If said sale is not consummated because of a default
under this Agreement or under any of the Other Agreements on the part of
Purchaser, the Deposit (but not the interest accrued thereon) shall be paid to
and retained by Seller as liquidated damages.  The parties have agreed that
Seller's actual damages, in the event of a default by Purchaser, would be
extremely





6
<PAGE>   7
difficult or impracticable to determine.  THEREFORE, BY PLACING THEIR INITIALS
BELOW, THE PARTIES ACKNOWLEDGE THAT THE DEPOSIT (AS WELL AS THE DEPOSIT UNDER
EACH OF THE OTHER AGREEMENTS) HAS BEEN AGREED UPON, AFTER NEGOTIATION, AS THE
PARTIES' REASONABLE ESTIMATE OF SELLER'S DAMAGES AND AS SELLER'S EXCLUSIVE
REMEDY AGAINST PURCHASER, AT LAW OR IN EQUITY, IN THE EVENT OF A DEFAULT UNDER
THIS AGREEMENT OR UNDER ANY OF THE OTHER AGREEMENTS ON THE PART OF PURCHASER.
NOTWITHSTANDING THE FOREGOING PROVISIONS OF THIS PARAGRAPH 7(a), THIS PARAGRAPH
7(a) SHALL NOT LIMIT ANY RECOVERY BY SELLER PURSUANT TO THE PROVISIONS OF
PARAGRAPHS 13, 17(b), 17(h), AND 17(l) BELOW OR PURSUANT TO THE PROVISIONS OF
PARAGRAPHS 13, 17(b), 17(h), AND 17(l) OF ANY OF THE OTHER AGREEMENTS.

                 INITIALS:    Seller _______            Purchaser _______

         b.      In the event the sale of the Property is not consummated
because of a material default under this Agreement on the part of Seller or a
material default under any of the Other Agreements on the part of the "Seller"
thereunder, which default is not cured within three (3) business days after
receipt of written notice from Purchaser, or if a Condition Precedent cannot be
fulfilled because Seller frustrated such fulfillment by some willful act,
Purchaser may elect, as its sole and exclusive remedy hereunder, to either (1)
terminate this Agreement by delivery of notice of termination to Seller,
whereupon (A) the Deposit (as well as the Deposit under each of the Other
Agreements) plus interest accrued thereon shall be immediately returned to
Purchaser, and (B) Seller shall pay to Purchaser any title, escrow, legal and
inspection fees incurred by Purchaser and any other expenses incurred by
Purchaser in connection with the negotiation of this Agreement and the Other
Agreements and Purchaser's pursuit of the transactions contemplated hereunder
and under the Other Agreements and the performance of its due diligence review
of the Property and the "Property" described in the Other Agreements,
including, without limitation, environmental and engineering consultants' fees
and expenses and legal fees, and neither party shall have any further rights or
obligations hereunder, or (2) continue this Agreement pending Purchaser's
action for specific performance.

8.       Closing and Escrow.

          a.     Upon mutual execution of this Agreement, the parties hereto
shall deposit an executed counterpart of this Agreement with Title Company and
this Agreement shall serve as instructions to Title Company for consummation of
the purchase and sale contemplated hereby.  Seller and Purchaser agree to
execute such additional escrow instructions as may be appropriate to enable the
escrow holder to comply with the terms of this Agreement; provided, however,
that in the event of any conflict between the





7
<PAGE>   8
provisions of this Agreement and any supplementary escrow instructions, the
terms of this Agreement shall control.

          b.     The parties shall conduct an escrow Closing pursuant to this
Paragraph 8 on or before September 4, 1997 or on such other date as Purchaser
and Seller may agree in their sole and absolute discretion (the "Closing
Date"), provided, however, that Purchaser shall have the right to extend the
Closing Date on one or more occasions for up to thirty (30) days in the
aggregate so long as Purchaser (i) delivers written notice to Seller not less
than ten (10) business days prior to the then scheduled Closing Date, (ii)
deposits an additional Forty-Five Thousand Dollars ($45,000.00) (the "Extension
Deposit") in escrow with Title Company, and (iii) similarly extends the
"Closing Date" under each of the Other Agreements and deposits with Title
Company the "Extension Deposits" thereunder, and Seller shall have the right to
extend the Closing Date with respect to affected Constituent Parcels for up to
sixty (60) days as set forth in Paragraphs 6(c) and 11(b) hereof.  Upon deposit
with Title Company, the Extension Deposit shall be non-refundable, except to
the extent that this Agreement terminates as a result of a Seller default or
the failure of a condition to Closing for the benefit of Purchaser.

          c.     At or before the Closing, Seller shall deliver to Purchaser
the following:

                 i.       the duly executed (and where appropriate
acknowledged) Deed, Bill of Sale, Assignment of Intangible Property and, to the
extent applicable, Assignment of Leases;

                 ii.      INTENTIONALLY OMITTED.

                 iii.     originals of all Leases (if any), Assumed Contracts,
and building permits, certificates of occupancy and plans and specifications
for the Improvements and all tenant-occupied space included within the

                 iv.      notices to the Tenants (if any) in form satisfactory
to Purchaser, duly executed by Seller;

                 v.       a "FIRPTA Affidavit" pursuant to Section 1445(b)(2)
of the Internal Revenue Code, duly executed by Seller;

                 vi.      such resolutions, authorizations, bylaws or other
corporate and/or partnership documents or agreements relating to Seller as
shall be required by the Title Company;

                 vii.     the certificate certifying as to Seller's
representations and warranties as required by Subparagraph 6(c) above;





8
<PAGE>   9
                 viii.    keys to all locks located in or about any portion of
the Property and all personal property described in the Bills of Sale to the
extent in Seller's possession or reasonable control; and

                 ix.      any other customary and/or reasonable closing
documents requested by the Title Company.

Purchaser may waive compliance on Seller's part under any of the foregoing
items by an instrument in writing.

          d.     At or before the Closing, Purchaser shall deliver to Seller
the following:

                 i.       the duly executed Assignment of Leases (if
applicable) and Assignment of Intangible Property;

                 ii.      such resolutions, authorizations, bylaws or other

                 iii.     any other customary and/or reasonable closing
documents requested by the Title Company;

                 iv.      in sufficient time to permit an 8:00 a.m. (Dallas
time) Closing, the balance of the Purchase Price in cash or other immediately
available funds, subject to prorations and adjustments as set forth herein.

          e.     Seller and Purchaser shall each deposit such other instruments
as are reasonably required by the escrow holder or otherwise required to close
the escrow and consummate the acquisition of the Property in accordance with
the terms hereof.  Seller and Purchaser hereby designate Title Company as the
"Reporting Person" for the transaction pursuant to Section 6045(e) of the
Internal Revenue Code and the regulations promulgated thereunder and agree to
execute such documentation as is reasonably necessary to effectuate such
designation.

          f.     The following are to be apportioned as of the Closing Date, as
follows:

                 i.       RENT.  Rent for the current month under the Leases
shall be apportioned as of the Closing Date, regardless of whether or not such
rent has been paid to Seller.  With respect to any rent arrearages arising
under the Leases, after Closing Purchaser shall pay on or before the 15th day
of each calendar month to Seller any rent actually collected during the
preceding month that is applicable to the period preceding the Closing Date;
provided, however, that all rent collected by Purchaser shall be applied first
to all unpaid rent accruing after the Closing Date, and then to unpaid rent
accruing prior to the Closing Date.  Purchaser shall use reasonable efforts for
a period of six (6) months after Closing to recover rent arrearages, provided
that Purchaser shall not be obligated to sue any Tenant, evict any Tenant or
institute any other legal or quasi-legal proceeding against any





9
<PAGE>   10
Tenant.  Seller shall not be permitted to take any steps to recover any rent
arrearages after Closing, provided that Seller shall have the right to commence
suit against a Tenant to recover rent arrearages for a period of six (6) months
after the Closing and prosecute such suit to completion and Seller shall have
the right to sue a Tenant at any time after such Tenant's Lease has expired or
otherwise terminates, provided that in no event shall Seller have the right to
bring either an unlawful detainer action or seek recourse to a Tenant's
security deposit transferred to Purchaser.

                 ii.      LEASING COSTS; TENANT INDUCEMENTS.  Seller shall pay
all leasing commissions and tenant improvement costs that arise in connection
with any Lease executed on or before the Contract Date.  With respect to any
new Lease or Lease extension or expansion entered into by Seller between the
Contract Date and the Closing Date and approved by Purchaser pursuant to the
terms of Paragraph 15(a) below, in the event that Seller incurs or pays any
costs or expenses for leasing commissions and/or tenant allowances or
improvements and/or free rent (collectively, "New Leasing Costs") in connection
with any such new Lease or such extension or expansion in excess of the gross
rental (including base rent, additional rent and pass-throughs) (collectively,
"New Leasing Revenue") received by Seller with respect to such new Lease or
such extension, Seller shall be entitled to a credit at the Closing for the
difference between the New Leasing Costs and the New Leasing Revenue.  With
respect to any free rent applicable to the period after the Closing that arises
under any new Lease or Lease extension or expansion entered into by Seller
between the Contract Date and the Closing Date and approved by Purchaser
pursuant to the terms of Paragraph 15(a) below, such free rent shall be
prorated between Seller and Purchaser based on the number of months (or
fractional months) in such new Lease or such extension or expansion that are
prior to the Closing Date and the number of such months (or fractional months)
that are after the Closing Date.

                 iii.     SECURITY DEPOSITS; PREPAID RENT.  Purchaser shall be
entitled to a credit against the Purchase Price for the total sum of all
security deposits (and interest earned thereon) that are required to be
returned to the Tenants under the terms of the respective Leases.
Additionally, Purchaser shall be entitled to a credit against the Purchase
Price for the total sum of all free rent, operating expense abatements, or
other unexpired concessions under any Leases executed prior to the Contract
Date to the extent they apply to any period after the Closing.

                 iv.      OTHER TENANT CHARGES.  For all items subject to
proration for which the landlord receives reimbursement from the tenants as
common area maintenance charges ("CAM Charges"), it is acknowledged that Seller
has prepaid certain CAM Charges and already received reimbursement on account
of certain estimated CAM Charges for the period prior to Closing and Purchaser
will similarly make certain payments and receive reimbursements on account of
CAM Charges for the period after Closing.  Seller shall be responsible for
collection of all estimated CAM Charges, including all delinquent amounts,
payable by the tenants prior to Closing, and Purchaser shall be responsible for





10
<PAGE>   11
collection of all estimated CAM Charges, including delinquent amounts, payable
by the tenants after Closing.  Consistent with the foregoing sentence,
Purchaser and Seller shall prorate the expense items which are subject to
reimbursement pursuant to the CAM Charges in such a way that Seller shall be
responsible for the payment of all costs and expenses which are intended to be
reimbursed by such CAM Charges for the period prior to Closing and Purchaser
shall be responsible for all such costs and expenses after Closing.  At the end
of the fiscal year applicable to the CAM Charges described in the preceding
sentences of this Section, to the extent that the landlord has received excess
CAM Charges and is obligated to reimburse to the tenants any portion of the
excess CAM charges collected by Seller, Seller shall, within ten (10) days of
written demand therefor, reimburse to Purchaser the portion of such excess CAM
Charges which have been paid to and retained by Seller.  In the event that at
the end of the fiscal year applicable to such CAM Charges, tenants on the
Property are obligated to pay to the landlord any sums on account of an
underpayment of CAM Charges, Purchaser shall pay to Seller immediately upon
receipt thereof Seller's prorata share of such reimbursement by the tenants.
Purchaser shall deliver to Seller at the same time that such notices are
delivered to the tenants any accounting or reconciliation of the CAM Charges
for the fiscal year in which the Closing occurs.

                 v.       UTILITY CHARGES.  Seller shall be responsible for the
cost of all utilities used prior to the Closing Date, except to the extent such
utility charges are billed to and paid by tenants directly.

                 vi.      OTHER APPORTIONMENTS; CLOSING COSTS.  Amounts payable
under the Assumed Contracts, annual or periodic permit and/or inspection fees
(calculated on the basis of the period covered), and liability for other
Property operation and maintenance expenses and other recurring costs shall be
apportioned as of the Closing Date.  Seller shall pay all transfer taxes and
sales tax (if any) on the Personal Property.  Seller shall pay the premium for
the Title Policy, provided that Purchaser shall pay the cost of the
Endorsements.  Purchaser acknowledges that if title to the Property and the
"Property" described and defined in the Other Agreements is taken in the name
of the same entity or entities, and unless business reasons (e.g. financing
requirements) dictate otherwise as determined by Purchaser in its good faith
discretion, Purchaser shall obtain one title policy covering both the Property
and the "Property" described and defined in the Other Agreements.  Seller and
Purchaser shall each pay fifty percent (50%) of all escrow and recording and
notary fees.  Seller shall be responsible for all costs incurred in connection
with the prepayment or satisfaction of any loan secured by the Property,
including, without limitation, any prepayment fees, penalties or charges.  All
other costs and charges of the escrow for the sale not otherwise provided for
in this Subparagraph 7(f)(vi) or elsewhere in this Agreement shall be allocated
in accordance with the applicable closing customs for Dallas County, Texas.

                 vii.     REAL ESTATE TAXES AND SPECIAL ASSESSMENTS.  General
real estate taxes payable for 1996 and all prior years (including subsequent
taxes and assessments for prior years due to change in land usage or ownership)
shall be paid by Seller.  General





11
<PAGE>   12
real estate taxes payable for 1997 shall be prorated by Seller and Purchaser as
of the Closing Date.  If the amount of general real estate taxes for 1997
cannot be determined on the Closing Date, Seller shall deposit with the Title
Company, from the Purchase Price, an amount equal to Seller's proportionate
share of the 1997 taxes based upon the most current estimate of such taxes,
assuming for estimating purposes that the Property shall be fully assessed.
Such deposit shall be held in escrow and all interest earnings on such deposit
shall be paid to Seller.  The Title Company shall retain such deposit to pay
Seller's share of the actual general real estate taxes payable for 1997, paying
any excess over to Seller.  Seller shall pay any deficiency, when such general
real estate taxes are known.

                 viii.    PRELIMINARY CLOSING ADJUSTMENT.  Seller and Purchaser
shall jointly prepare a preliminary Closing adjustment on the basis of the
Leases and other sources of income and expenses, and shall deliver such
computation to Title Company not less than 10 days prior to Closing.

                 ix.      POST-CLOSING RECONCILIATION.  If any of the aforesaid
prorations cannot be calculated accurately on the Closing Date, then they shall
be calculated as soon after the Closing Date as feasible.  Either party owing
the other party a sum of money based on such subsequent proration(s) shall
promptly pay said sum to the other party, together with interest thereon at the
rate of the lesser of (A) two percent (2%) over the average "prime rate" (as
announced from time to time in the Wall Street Journal) per annum or (B) the
highest legally permitted rate, from the Closing Date to the date of payment if
payment is not made within ten (10) days after delivery of a bill therefor.

         SURVIVAL.  The provisions of this Subparagraph 8(f) shall survive the
Closing.

9.       Representations and Warranties of Seller.

Seller hereby represents and warrants to Purchaser as follows:

          a.     Except to the extent set forth on Schedule 2 attached hereto

the Tenants has either filed or been the subject of any filing of a petition
under the Federal Bankruptcy Law or any federal or state insolvency laws or
laws for composition of indebtedness or for the reorganization of debtors that
remains pending, except to the extent set forth on the Disclosure Schedule.

          l.     No brokerage or similar fee is due or unpaid by Seller with
respect to any Lease.  Except to the extent set forth on the Disclosure
Schedule, no brokerage or similar fee shall be due or payable on account of the
exercise of, without limitation, any renewal, extension or expansion options
arising under any Lease.

Except as set forth in this Agreement or in any document executed pursuant to
or in connection with this Agreement, the parties hereto acknowledge and agree
that the sale of the Property to Purchaser is made on an "AS-IS, WHERE-IS" and
"WITH ALL FAULTS" basis, and Seller makes no warranty or representation,
express or implied, as to merchantability, suitability or fitness for a
particular purpose, the state of repair of the Property or the physical
condition thereof.  The parties further agree, however, that this paragraph
does not affect an assumption of any liability by Purchaser and that this
paragraph shall not be construed as to waive any rights of contribution or
indemnity or otherwise affect the liabilities of the parties to each other or
to third parties under any environmental law, including CERCLA.  The provisions
of this paragraph shall survive the Closing and the delivery and recordation of
the Deed.

The representations and warranties set forth in this Paragraph 9 shall survive
the Closing for the period set forth in Paragraph 17(e) below.

          b.     Purchaser has neither filed nor been subject to the filing of

The representations and warranties set forth in this Paragraph 10 shall survive
the Closing for the period set forth in Paragraph 17(e) below.

11.      Other Agreements.

          a.     Notwithstanding anything to the contrary in this Agreement,
but subject to the provisions of Paragraph 11(b) below, it shall be a condition
precedent to both Purchaser's obligation to purchase the Property hereunder and
to Seller's obligation to sell the Property hereunder that the "Closing" under
and as defined in each of those three other Purchase Agreements dated as of
even date herewith and identified on Schedule 3 attached hereto (the "Other
Agreements") occurs concurrently with the Closing hereunder.  The parties
acknowledge and agree that a default by Seller under this Agreement shall be
deemed a default of each of the "Sellers" under each of the Other Agreements
and that a default by a "Seller" under any of the Other Agreements shall be
deemed a default by Seller hereunder.  The parties further acknowledge and
agree that a default by Purchaser under this Agreement shall be deemed a
default of each of the "Purchasers" under each of the Other Agreements and that
a default by a "Purchaser" under any of the Other Agreements shall be deemed a
default by Purchaser hereunder.

         b.      Notwithstanding anything to the contrary provided in Paragraph
11(a) above or elsewhere in this Agreement or any Other Agreement, in the event
that (i) Purchaser discovers during the Due Diligence Period that a Constituent
Parcel (as defined below) is in material violation of any Environmental Law
(but only if Seller fails to cure such violation prior to the Closing Date, as
such may be extended pursuant to this Paragraph 11(b), and Seller is unwilling
to give Purchaser a credit at Closing in such amount as the parties agree upon
will compensate Purchaser for such matter, it being acknowledged by the parties
hereto that Seller shall not be obligated hereunder to elect to cure any such
violation or offer to give Purchaser such a credit), (ii) Purchaser discovers
during the Due Diligence Period that there is a material defect in title that
adversely





15
<PAGE>   16
affects the marketability or financability of the Constituent Parcel (but only
if Seller fails to remedy such defect prior to the Closing Date, as such may be
extended pursuant to this Paragraph 11(b), and Seller is unwilling to give
Purchaser a credit at Closing in such amount as the parties agree upon will
compensate Purchaser for such matter, it being acknowledged by the parties
hereto that Seller shall not be obligated hereunder to elect to remedy any such
defect or offer to give Purchaser such a credit), (iii) Purchaser determines
during the Due Diligence Period that the net operating income derived from the
Property and the "Property" described and defined in the Other Agreements
differs in any material respect in the aggregate from that set forth in any
materials delivered to Purchaser by Seller or its agents prior to Purchaser's
execution of this Agreement or on the Rent Roll (as defined below) and
one-third (() or more of such discrepancy is attributable to any Constituent
Parcel (but only to the extent Seller is unwilling to give Purchaser a credit
at Closing in an amount equal to such loss of income, capitalized at the same
rate as that reflected by the Purchase Price, it being acknowledged by the
parties hereto that Seller shall not be obligated hereunder to offer to give
Purchaser such a credit), (iv) any of Seller's representations and warranties
is not true and correct in all material respects at Closing with respect to a
Constituent Parcel, (v) Purchaser discovers during the Due Diligence Period
that there is a material defect in the physical condition of a Constituent
Parcel as disclosed in an independent third party structural or physical report
obtained by Purchaser (but only if Seller fails to repair all such physical
conditions prior to the Closing Date, as such may be extended pursuant to this
Paragraph 11(b), and Seller is unwilling to give Purchaser a credit at Closing
in such amount as the parties agree upon will compensate Purchaser for such
matter, it being acknowledged by the parties hereto that Seller shall not be
obligated hereunder to elect to repair such conditions or offer to give
Purchaser such a credit), or (vi) Purchaser elects to terminate this Agreement
as to a Constituent Parcel pursuant to Paragraph 12 below, Purchaser shall have
the right to terminate this Agreement as to such affected Constituent Parcels
only (each such Constituent Parcel being referred to herein as a "Removed
Parcel"), in which event this Agreement shall be amended to delete all
references to the Removed Parcel(s), the Purchase Price shall be reduced by the
amount allocated to the Removed Parcel(s) as set forth on Schedule 4 attached
hereto, and this Agreement and the Other Agreements shall otherwise remain in
full force and effect; provided, however, that with respect to the
circumstances described in clauses (i), (ii), (iii) and (v) above, Purchaser's
right of termination shall be conditioned upon Purchaser's informing Seller in
writing prior to the end of the Due Diligence Period that Purchaser will
terminate this Agreement as to such affected Constituent Parcel if such matter
is not cured or remedied or Purchaser is not otherwise compensated, as
applicable, prior to the Closing.  Seller shall have the right to extend the
Closing Date with respect to any affected Parcel for up to sixty (60) days to
remedy or cure any such objectionable matter, provided that Seller (i) delivers
written notice to Purchaser within five (5) days after the end of the Due
Diligence Period, which notice shall state that Seller is electing to extend
the Closing Date and that Seller will use all commercially reasonable efforts
to cure or remedy such matter, and (ii) thereafter diligently proceeds to
attempt to cure or remedy such matter.





16
<PAGE>   17
The sixty (60) day period set forth in the immediately preceding sentence shall
run concurrent with the sixty (60) day period set forth in Paragraph 6(c)
above.

          c.     Notwithstanding anything to the contrary provided in Paragraph
11(a) above or elsewhere in this Agreement or any Other Agreement, in the event
that the Removed Parcel(s) constitute(s) the entire Property, Purchaser shall
have the right to terminate this Agreement in its entirety, but elect to keep
the Other Agreements in full force and effect.

          d.     As used herein, the term "Constituent Parcel" shall mean
either Lot 1, Block 4 or Lot 1, Block 1, as shown on Exhibit A hereto, together
with and all other portions of the Property properly allocable thereto.

12.      Risk of Loss.

          a.     Purchaser shall be bound to purchase the Property for the full
Purchase Price as required by the terms hereof, without regard to the
occurrence or effect of any damage to the Property or destruction of any
improvements thereon or condemnation of any portion of the Property, provided
that (i) the cost to repair any such damage or destruction to a Constituent
Parcel, or the diminution in the value of the remaining Property as a result of
a partial condemnation, does not exceed $250,000 (and the cost to repair all
such damage or destruction to, or the diminution in value of, the Property and
the "Property" described and defined in the Other Agreements, in the aggregate,
does not exceed $1,000,000), and (ii) upon the Closing, there shall be a credit
against the Purchase Price due hereunder equal to the amount of any insurance
proceeds or condemnation awards collected by Seller as a result of any such
damage or destruction or condemnation, less any sums reasonably expended by
Seller toward the restoration or repair of the affected Property, and, if the
proceeds or awards have not been collected as of the Closing, then such
proceeds or awards shall be assigned to Purchaser.

          b.     If the amount of the damage or destruction or condemnation as
specified in Paragraph 12(a) above exceeds $250,000 with respect to any
Constituent Parcel, then Purchaser may, at its option to be exercised within
twenty (20) days of Seller's written notice of the occurrence of the damage or
destruction or the commencement of condemnation proceedings, either terminate
this Agreement in its entirety or solely with respect to such Constituent
Parcel or consummate the purchase for the full Purchase Price as required by
the terms hereof.  Similarly, if the amount of the damage or destruction or
condemnation as specified in Paragraph 12(a) above exceeds $1,000,000 with
respect to the Property and the "Property" described and defined in the Other
Agreements, in the aggregate, then Purchaser may, at its option to be exercised
within twenty (20) days of Seller's written notice of the occurrence of the
damage or destruction or the commencement of condemnation proceedings, either
terminate this Agreement in its entirety or consummate the purchase for the
full Purchase Price as required by the terms hereof.  If Purchaser elects to
terminate this Agreement in its entirety or fails to give Seller written notice
within such 20-day period that Purchaser will proceed with the purchase, then
the Deposit shall be immediately returned to Purchaser and neither party





17
<PAGE>   18
shall have any further rights or obligations hereunder, except to the extent
expressly otherwise set forth herein.  If Purchaser elects to terminate this
Agreement solely with respect to such affected Constituent Parcel, the
provisions of Paragraph 11(b) above shall control.  If Purchaser elects to
proceed with the purchase as to the entire Property, then upon the Closing,
there shall be a credit against the Purchase Price due hereunder equal to the
amount of any insurance proceeds or condemnation awards collected by Seller as
a result of any such damage or destruction or condemnation, less any sums
reasonably expended by Seller toward the restoration or repair of the affected
Property, and, if the proceeds or awards have not been collected as of the
Closing, then such proceeds or awards shall be assigned to Purchaser.

          c.     In the event that Purchaser is required to or elects to
purchase the entire Property following any damage or destruction or
condemnation of the Property pursuant to Paragraph 12(a) or (b) above, Seller
shall also provide Purchaser with a credit against the Purchase Price in an
amount equal to any deductible or uninsured amount; provided, however, in no
event shall Seller be required to provide Purchaser with a credit pursuant to
this Paragraph 12(c) in an amount that exceeds $250,000 with respect to any
Constituent Parcel or that exceeds $1,000,000 with respect to the Property and
the "Property" described and defined in the Other Agreements, in the aggregate.
If it is determined that the deductible or uninsured amount is greater than
$250,000 (or $1,000,000, as applicable), Seller shall notify Purchaser in
writing as soon as reasonably possible following such determination whether or
nor Seller is willing to provide Purchaser with a credit against the Purchase
Price in the full amount of such deductible or uninsured amount.  In the event
that Seller is unwilling to provide Purchaser with a credit in such full
amount, Purchaser shall have the right to terminate this Agreement by
delivering written notice to Seller within twenty (20) days after Purchaser=s
receipt of such notice from Seller.  If Purchaser elects to terminate this
Agreement or fails to give Seller written notice within such twenty (20) day
period that Purchaser will proceed with the purchase, the Deposit shall be
immediately returned to Purchaser and neither party shall have any further
obligations hereunder, except to the extent expressly otherwise set forth
herein.

13.      Possession.

         Possession of the Property shall be delivered to Purchaser on the
Closing Date subject only to the rights of Tenants under the Leases, provided,
however, that prior to the Closing Date Seller shall afford authorized
representatives of Purchaser (as well as any actual or prospective lender to
Purchaser) reasonable access to the Property, upon 24 hours notice, for
purposes of satisfying Purchaser (and such lender) with respect to the
representations, warranties and covenants of Seller contained herein and with
respect to satisfaction of any Diligence Period Condition or any Condition
Precedent (including, without limitation, the Condition Precedent set forth in
Paragraph 6(d) above) and for the purpose of conducting Tenant interviews,
provided that prior to entering the Property Purchaser shall (i) obtain
comprehensive general liability insurance in an amount not less





18
<PAGE>   19
than $1,000,000 naming Seller as an additional insured and (ii) provide a copy
of such policy or a certificate evidencing such coverage to Seller.  Purchaser
hereby agrees to indemnify and hold Seller harmless from any damage or injury
to persons or property caused by Purchaser or its authorized representatives
during their entry and investigations prior to the Closing, provided the
foregoing shall not require Purchaser to indemnify Seller or any other person
with respect to any conditions that are discovered by Purchaser as opposed to
being first caused by Purchaser.  If this Agreement is terminated, Purchaser
shall repair the damage caused by Purchaser's entry and investigations,
provided the foregoing shall not require Purchaser to repair or remediate any
conditions that are discovered by Purchaser as opposed to being first caused by
Purchaser.  The foregoing indemnity shall survive the termination of this
Agreement or the Closing, as applicable.

14.      Maintenance of the Property; Miscellaneous Covenants.

         Between the Contract Date and the Closing, Seller shall perform all of
the landlord's obligations under the Leases and shall otherwise operate and
maintain the Property in the same manner as before the making of this
Agreement, as if Seller were retaining the Property.  Seller shall promptly
notify Purchaser of any condemnation, environmental, zoning or other land-use
regulation proceedings of which Seller becomes aware, as well as any notices of
violations of any Laws relating to the Property of which Seller becomes aware
and any litigation of which Seller becomes aware that arises out of the
ownership of the Property or that might detrimentally affect the value or the
use or operation of the Property or the ability of Seller to perform its
obligations hereunder.  Following the Contract Date, Seller shall continue to
prepare Operating Statements (as defined in Exhibit G hereto) for the Property
as to all time periods subsequent to the dates of the Operating Statements
delivered to Purchaser as part of the Delivery Items and prior to the Closing
Date, which Operating Statements shall be delivered to Purchaser within a
reasonable period of time following the end of the period with respect to which
such Operating Statements are prepared, even if prepared after Closing.
Through the Closing Date, Seller shall maintain or cause to be maintained, at
Seller's sole cost and expense, all policies of insurance currently in effect
with respect to the Property (or comparable replacements thereof).

15.      Purchaser's Consent to New Contracts Affecting the Property;
         Termination of Existing Contracts.

          a.     Seller shall not, after the Contract Date, enter into any
Lease or contract, or any amendment thereof, or permit any Tenant to enter into
any sublease, assignment or agreement pertaining to the Property, or waive any
rights of Seller under any contract or Lease, without in each case obtaining
Purchaser's prior written consent thereto, which consent in the case of any
Lease shall include approval of the financial condition of the proposed tenant,
the configuration of the space to be leased, and the terms of such Lease
(including, without limitation, the rent and any concessions provided under
such proposed Lease), and which consent shall not be unreasonably withheld by
Purchaser.  Seller shall be entitled, without the consent of Purchaser, to
enter into, amend or





19
<PAGE>   20
otherwise deal with service contracts and similar agreements that are not
Assumed Contracts in the ordinary course of business that are terminable on not
more than thirty (30) days' prior notice and which shall not be binding on
Purchaser after the Closing Date.  Seller shall deliver to Purchaser, together
with any request for approval of a new Lease, a copy of the proposed Lease, a
description of the proposed Tenant and its proposed use of the premises and
whatever financial information on the proposed Tenant Seller has received, as
well as any additional information reasonably requested by Purchaser
(including, without limitation, if applicable, an environmental questionnaire).
Notwithstanding anything to the contrary provided in this Subparagraph 15(a),
if Purchaser fails to respond in writing with respect to any such new Lease or
other action requiring Purchaser's consent under this Subparagraph 15(a) within
five (5) business days after Purchaser's receipt of such request and
information, Purchaser shall be deemed to have approved such new Lease or other
action.

          b.     Seller shall terminate prior to the Closing, at no cost or
expense to Purchaser, any and all management agreements, service contracts or
similar agreements affecting the Property that are not Assumed Contracts.

          c.     Seller shall not, after the Contract Date, create any new
encumbrance or lien affecting the Property other than liens and encumbrances
(i) that are reasonably capable of being discharged prior to the Closing and
(ii) that in fact will be and are discharged prior to the Closing.

16.      Cooperation with Purchaser.

   Seller shall cooperate and do all acts as may be reasonably required or
requested by Purchaser with regard to the fulfillment of any Condition
Precedent including execution of any documents, applications or permits
reasonably requested by Purchaser and, to the extent requested by Purchaser,
agrees to cooperate with Purchaser's efforts to obtain subordination,
non-disturbance and attornment agreements from the Tenants.  Seller hereby
authorizes Purchaser and its agents to make all inquiries with and applications
to any third party, including any governmental authority, as Purchaser may
reasonably require to complete its due diligence.

17.      Miscellaneous.

          a.     NOTICES.  Any notice, consent or approval required or
permitted to be given under this Agreement shall be in writing and shall be
deemed to have been given upon (i) hand delivery, (ii) one (1) business day
after being deposited with Federal Express or another reliable overnight
courier service, with receipt acknowledgment requested, (iii) upon receipt if
transmitted by facsimile telecopy, or (iv) upon receipt or refused delivery

subject matter of this transaction, through any real estate broker or other
person who can claim a right to a commission or finder's fee in connection with
the sale contemplated herein, except for Cushman & Wakefield of Texas, Inc.
("Broker"), whose commission shall be paid by Seller pursuant to the terms of a
separate agreement between Seller and Broker.  In the event that any other
broker or finder makes a claim for a commission or finder's fee based upon any

the broker or finder making its claim shall indemnify, defend and hold harmless
the other party against and from any commission, fee, liability, damage, cost

the Closing.

          c.     SUCCESSORS AND ASSIGNS.  This Agreement shall be binding upon,
and inure to the benefit of, the parties hereto and their respective
successors, heirs, administrators and assigns.  Notwithstanding the foregoing,
Purchaser shall not have the right, without the prior written approval of
Seller, to assign this Agreement in whole or in part, provided that Purchaser
may assign this Agreement upon notice to Seller (but without any





21
<PAGE>   22
requirement of obtaining Seller's consent) in whole or in part to (i) one or
more entities in which Marc R. Brutten, Jay H. Shidler and/or James C.
Reynolds, directly or indirectly, has an ownership interest, and/or (ii) an
entity controlled or managed by, or otherwise affiliated with, Angelo Gordon &
Co., provided that such assignee(s) shall assume all of the obligations of
Purchaser hereunder and the foregoing shall not act as a release of the party
originally designated as Purchaser hereunder.  To the extent that any indemnity
set forth in this Agreement is made for the benefit of Purchaser or Seller, the
term "Purchaser" or "Seller", as applicable, as it pertains to an indemnified
party only, shall include the managers, members, investors, affiliates,
lenders, officers, directors, shareholders, partners, trustees, beneficiaries,
agents and employees of such party and their respective heirs, representatives,

          e.     CONTINUATION AND SURVIVAL OF REPRESENTATIONS AND WARRANTIES,
ETC.  All representations and warranties by the respective parties contained
herein or made in writing pursuant to this Agreement are intended to and shall
remain true and correct as of the time of Closing, shall be deemed to be
material, and, together with all conditions, covenants and indemnities made by
the respective parties contained herein or made in writing pursuant to this
Agreement, shall survive the execution and delivery of this Agreement and the
Closing for a period of 12 months, or, to the extent the context requires,
beyond any termination of this Agreement.  In the event that a claim is not
made with respect to a breach of a representation, warranty or covenant set
forth herein within such 12 month period, such claim shall be deemed waived.

          f.     GOVERNING LAW.  This Agreement shall be governed by and
construed in accordance with the laws of the State of Texas.

          g.     MERGER OF PRIOR AGREEMENTS.  This Agreement and the exhibits
and schedules hereto constitute the entire agreement between the parties and
supersede all prior agreements and understandings between the parties relating
to the subject matter hereof.

          h.     ENFORCEMENT.  If either party hereto fails to perform any of
its obligations under this Agreement or if a dispute arises between the parties
hereto concerning the meaning or interpretation of any provision of this
Agreement, then the defaulting party or the party not prevailing in such
dispute shall pay any and all costs and expenses incurred by the other party on
account of such default and/or in enforcing or establishing its rights
hereunder, including, without limitation, court costs and attorneys' fees and
disbursements.  Any such attorneys' fees and other expenses incurred by either
party in enforcing a judgment in its favor under this Agreement shall be
recoverable separately from and in addition to any other amount included in
such judgment, and such attorneys' fees obligation is intended to be severable
from the other provisions of this Agreement and to survive and not be merged
into any such judgment.





22
<PAGE>   23
          i.     TIME OF THE ESSENCE.  Time is of the essence of this
Agreement.

          j.     SEVERABILITY.  If any provision of this Agreement, or the
application thereof to any person, place, or circumstance, shall be held by a
court of competent jurisdiction to be invalid, unenforceable or void, the
remainder of this Agreement and such provisions as applied to other persons,
places and circumstances shall remain in full force and effect.

          k.     MARKETING.  During the term of this Agreement, Seller shall
not list the Property with any broker or otherwise solicit or make or accept
any offers to sell the Property, engage in any discussions or negotiations with
any third party with respect to the sale or other disposition of the Property,
or enter into any contracts or agreements (whether binding or not) regarding
any disposition of the Property.

          l.     CONFIDENTIALITY.  Each party agrees to maintain in confidence,
and not to disclose to any third party, the information contained in this
Agreement or pertaining to the sale contemplated hereby and the information and
data furnished or made available by Seller to Purchaser, its agents and
representatives in connection with Purchaser's investigation of the Property
and the transactions contemplated by the Agreement; provided, however, that
each party, its agents and representatives may disclose such information and
data (a) to such party's accountants, attorneys, prospective lenders,
accountants, partners, consultants and other advisors in connection with the
transactions contemplated by this Agreement (collectively "Representatives") to
the extent that such Representatives reasonably need to know (in Purchaser's or
Seller's reasonable discretion) such information and data in order to assist,
and perform services on behalf of, Purchaser or Seller; (b) to the extent
required by any applicable statute, law, regulation, governmental authority or
court order; and (c) in connection with any litigation that may arise between
the parties in connection with the transactions contemplated by this Agreement.
In the event of any conflict between the terms of this Section 17(l) and the
terms of the Confidentiality Agreement referenced in Section 17(g) above, the
terms of said Confidentiality Agreement shall control.  Each party shall
consult with the other party prior to making any press release or other
disclosure intended for general circulation regarding the transactions
contemplated hereunder.  In no event shall any such disclosure or press release
contain the purchase price.

          m.     SECTION 1031 EXCHANGE.  It is presently contemplated that
Purchaser and Seller may each desire to effectuate a tax-deferred exchange
(also known as a "1031" exchange) (an "Exchange") in connection with the
purchase and sale of the Property.  Purchaser and Seller hereby agree to
cooperate with each other in connection with one or more such Exchanges,

         A.      Seller and Purchaser entered into that certain Purchase
Agreement, dated as of July 2, 1997, as amended by that certain First Amendment
to Purchase Agreement dated as of July 30, 1997 (collectively, the "Purchase
Agreement").  Each capitalized term used in this Second Amendment, but not
defined herein, shall have the meaning ascribed to it in the Purchase
Agreement.

         B.      Seller and Purchaser desire to amend the Purchase Agreement as
set forth in this Second Amendment.

         NOW, THEREFORE, the parties agree as follow:

approve any title exceptions first disclosed to Purchaser subsequent to the end

In order to induce the Company and the Operating Partnership to enter into this

under the laws of the jurisdiction in which it was organized, is duly authorized
to transact business under the laws of each state in which the transaction of
its business makes such qualification necessary, and has all requisite corporate
power and authority to execute and deliver this Agreement and all other
documents and instruments to be executed and delivered by it hereunder and to
perform its obligations hereunder and thereunder in accordance with the terms
and conditions hereof and thereof.                                   

                 (b)      Authorization; No Violation. Assuming the due and
valid authorization, execution and delivery of this Agreement by the
Transferee, this Agreement, and the other agreements and documents to be
executed by the Contributor hereunder, will be the legal, valid and binding
obligation of the Contributor, enforceable against the Contributor in
accordance with their respective terms, subject to applicable bankruptcy,
insolvency, moratorium or similar laws relating to creditors' rights and
general principles of equity. The performance by the Contributor of its duties
and obligations under this Agreement and the documents and instruments to be
executed and delivered by it hereunder will not conflict with, or result in a
breach of, or default under, any provision of any of the organizational
documents of the Contributor or any agreement, instrument, decree, judgment,
injunction, order, writ, law, rule or regulation, or any determination or award
of any court or arbitrator, to which the Contributor is a party or by which its
assets are or may be bound (a "LEGAL REQUIREMENT"), require any consent,
approval or authorization of, declaration, filing or registration with, or
notice to, (a "THIRD PARTY CONSENT") any federal, state or local governmental
or regulatory authority having jurisdiction over the Property or the
Contributor (a "GOVERNMENTAL AUTHORITY") or any other person or entity. 

                 (c)      Existence of Agreements and Leases. To the
Contributor's knowledge, except as reflected in the Inspection Materials, there
are no material service contracts, management or maintenance agreements, leases
or other material agreements affecting the use or occupancy of the Property. To
the Contributor's knowledge, the Inspection Materials heretofore delivered by
the Contributor to the Operating Partnership or its representatives for
examination constitute complete copies of all documents, information and
materials in the Contributor's possession relating to the Property and the
Purchase Agreements excluding interim drafts and other similar items that could
not be reasonably anticipated to have any effect whatsoever on the Transferee's
valuation of the Property.

                  (d)     Litigation.  The Contributor has no knowledge of any 
litigation, claim, audit, action, or proceeding pending or threatened before or

adversely affecting the ability of the Contributor to perform any of its
obligations hereunder.

                  (e)     Solvency; Bankruptcy. The Contributor is solvent,
and has not made a general assignment for the benefit of creditors or a
transfer in fraud of creditors, or been adjudicated a bankrupt or insolvent,

reports regarding the Property in its possession as part of the Inspection
Materials.

                  (h)      The Contributor Not a Foreign Person.  The

Revenue Code of 1986, as amended.

                  (i)      No Known Breach.  To the Contributor's knowledge,

ARTICLE 5.       REPRESENTATIONS AND WARRANTIES OF THE OPERATING PARTNERSHIP 
                 AND THE COMPANY.

         Section 5.1     The Transferee's Representations and Warranties. In
order to induce the Contributor to enter into this Agreement and to perform its
obligations hereunder, the Operating Partnership and the Company hereby jointly
and severally warrant and represent the following:                           

                  (a)    Organization, Good Standing and Power of the Company.
The Company is a real estate investment trust duly organized and validly
existing under the laws of the State of Texas, is duly authorized to transact
business under the laws of any state in which the character of the properties
owned or leased by it therein or in which the transaction of its business makes
such qualification necessary and has all requisite trust power and authority to
execute and deliver this Agreement and all other documents and instruments to be
executed and delivered by it hereunder and to perform its obligations hereunder
and thereunder in accordance with the terms and conditions hereof and thereof.

                  (b)    Organization, Valid Existence and Partnership Power of
the Operating Partnership. The Operating Partnership is a limited partnership
duly organized and validly existing under the laws of the State of Delaware, is
duly authorized to transact business under the laws of any state in which the
character of the properties owned or leased by it therein or in which the
transaction of its business makes such qualification necessary, and has all
requisite partnership power and authority to execute and deliver this Agreement
and all other documents and instruments to be executed and delivered by it
hereunder and to perform its obligations hereunder and thereunder in accordance
with the terms and conditions hereof and thereof.

                  (c)    Authorization; No Violation. Assuming the due and
valid authorization, execution and delivery of this Agreement by the
Contributor, this Agreement and the other agreements and documents to be
executed and delivered by each of the Operating Partnership and the Company
hereunder, when duly executed and delivered, will be the legal, valid and
binding obligation of each of the Operating Partnership and the Company,
enforceable against the Operating Partnership and the Company in accordance with
their respective terms, subject to applicable bankruptcy, insolvency, moratorium
or similar laws relating to creditors' rights and general            



                                       6

<PAGE>   12

principles of equity. The performance by each of the Operating Partnership and
the Company of its respective duties and obligations under this Agreement and
the documents and instruments to be executed and delivered by each of them
hereunder will not (i) conflict with, or result in a breach of, or default
under, any provision of any of the organizational documents of either of the
Operating Partnership or the Company or any agreements, instruments or Legal
Requirements to which either of the Operating Partnership or the Company is a
party or by which the assets of either are or may be bound, or (ii) require any
consent, approval or authorization of, or declaration, filing or registration
with, or notice to, any Governmental Authority.

                  (d)    Solvency; Bankruptcy. The Company and the Operating
Partnership is each solvent and each has not made a general assignment for the
benefit of creditors or a transfer in fraud of creditors, or been adjudicated,
bankrupt or insolvent, nor has a receiver, liquidator, custodian, or trustee of
the Company or the Operating Partnership or any of their respective properties
been appointed or taken possession of any of their respective properties, or a
petition filed by or against the Company or the Operating Partnership for
bankruptcy, composition, rearrangement, extension, reorganization, or
insolvency or bankruptcy law or statute, or any proceeding instituted for the
dissolution or liquidation of either the Company or the Operating Partnership.

                  (e)     OP Units, Warrants and Shares. The OP Units to be
issued to the Contributor Parties are duly authorized and, when issued by the
Operating Partnership, will be fully paid and non-assessable, free and clear of
any mortgage, pledge, lien, encumbrance, security interest, claim or rights of
interest of any third party of any nature whatsoever. The Shares to be issued by
the Company upon conversion of the OP Units or exercise of the Company Warrants
will be, upon such issuance, fully paid and non-assessable, free and clear of
any mortgage, pledge, lien, encumbrance, security interest, claim or rights of
interest of any third party of any nature whatsoever. The Company shall at all
times reserve and maintain a sufficient number of authorized but unissued Shares
to permit it to issue and deliver the Shares obtained upon conversion of the OP
Units and exercise the Company Warrants.               

                 (f)      Litigation.  Except as set forth in Schedule 5.1(f),
there is no pending or, to the Transferee's knowledge, threatened litigation
against the Operating Partnership or the Company that if adversely determined
would have a material adverse effect on the Transferee or its ability to
perform its obligations under this Agreement in a timely manner.

         Section 5.2      No Liability for Exception Matters.

         (a) As used herein, the term "Exception Matter" shall refer to a
matter disclosed to the Transferee in writing after the Effective Date hereof,
referenced in any document, report, or other item delivered to the Transferee
by the Contributor or its agents or otherwise obtained or reviewed by the
Transferee, or discovered by the Transferee, before the Closing, that
constitutes, as of the date of this Agreement, a breach of a representation or
warranty of the Contributor contained in this Agreement or in any document or
instrument delivered pursuant hereto. Under no circumstances shall the
Contributor have any obligation to cure or remedy any Exception Matter.



                                       7

<PAGE>   13



         (b) The Transferee shall promptly notify the Contributor in writing of
any Exception Matter of which the Transferee obtains knowledge before the
Closing, and of any matter discovered by Transferee prior to the Closing that
constitutes, as of the date of this Agreement, a breach of a representation or
warranty of the Contributor contained in this Agreement. Upon receipt of any
such written notice from the Contributor, the Transferee shall have the right
to terminate this Agreement by written notice to the Contributor and the
Company and receive an immediate return of the Earnest Money. If the Transferee
obtains knowledge of any Exception Matter before the Closing, but nonetheless
elects to proceed with the Closing hereunder, the Transferee shall consummate
the transactions contemplated by this Agreement subject to such Exception
Matter and the Contributor shall have no liability with respect to such
Exception Matter, notwithstanding any contrary provision, covenant,
representation or warranty contained in this Agreement. If the Transferee
elects to terminate this Agreement on the basis of any Exception Matter, the
Earnest Money shall be immediately returned to the Transferee and neither party
shall have any further rights or obligations hereunder, except as otherwise
expressly provided herein. Notwithstanding anything to the contrary contained
herein, the Contributor shall have no liability whatsoever to the Transferee
with respect to any Exception Matters.

         Section 5.3     The Transferee's Independent Investigation. THE 
TRANSFEREE SPECIFICALLY ACKNOWLEDGES AND AGREES THAT CONTRIBUTOR IS ASSIGNING
ITS RIGHTS TO ACQUIRE THE PROPERTY PURSUANT TO THE PURCHASE AGREEMENTS, AND THE
TRANSFEREE IS ACCEPTING SUCH ASSIGNMENT, ON AN "AS IS WITH ALL FAULTS" BASIS
AND THAT THE TRANSFEREE IS NOT RELYING ON ANY REPRESENTATIONS OR WARRANTIES OF
ANY KIND WHATSOEVER, EXPRESS OR IMPLIED, FROM THE CONTRIBUTOR, ITS AGENTS, OR
BROKERS AS TO ANY MATTERS CONCERNING THE PURCHASE AGREEMENTS, THE INSPECTION
MATERIALS OR THE PROPERTY EXCEPT AS EXPRESSLY SET FORTH IN SECTION 4.1 ABOVE.

ARTICLE 6.       COVENANTS.

         Section 6.1     Covenants of the Contributor. The Contributor covenants
and agrees that between the Effective Date and the Closing Date, unless the
Transferee has consented in writing to any other act or omission which shall not
be unreasonably withheld, delayed or conditioned, it shall perform or observe
the following:                                                              

                 (a)     The Contributor shall enforce Merit's obligations under
the Purchase Agreements and shall exercise its rights under the Purchase
Agreements in the same manner as the Contributor would enforce such obligations
and exercise such rights had the Contributor not entered into this Agreement,
provided that in no event shall the Contributor be obligated to commence
litigation to enforce any such obligations.

                 (b)     The Contributor will comply in all material respects
with its obligations set forth in the Purchase Documents and will not terminate
or amend the Purchase Agreements or (to the extent permitted in the Purchase
Agreements) consent to Merit entering into any new agreements
                                                                              


                                      8

or leases affecting the Property or to Merit extending, renewing, amending,
canceling or terminating any existing agreements or leases affecting the
Property without first receiving the Operating Partnership's prior written
consent which shall not be unreasonably, withheld, delayed or conditioned.

                  (c)    If the Contributor obtains actual knowledge of any
error or omission in any Inspection Material or in any representation or
warranty made in Section 4.1, the Contributor will give the Operating
Partnership prompt written notice thereof accompanied by reasonably detailed
information.
                                                                            
                  (d)    The Contributor shall promptly give the Operating
Partnership written notice of, and promptly deliver to the Operating
Partnership, a true and complete copy of any written notice the Contributor may
receive, on or before the Closing Date, from any Governmental Authority,
concerning a violation of any applicable Legal Requirement pertaining to the
Property or of any written notice of default from Merit under the Purchase
Agreements.

                  (e)    At Closing, the Contributor Parties shall execute and
deliver: (i) the amended and restated agreement of limited partnership of the
Operating Partnership (the "OP AGREEMENT") in the form attached hereto as
Exhibit 6.1(f), and (ii) the Warrant Agreements. 

                  (f)    The Contributor, without cost or expense to the
Contributor, shall cooperate to the extent reasonably requested in the
preparation by the Company of any reports, registration statements or other
filings required to be filed by the Company with the Securities and Exchange
Commission ("SEC") relating to the transactions contemplated hereunder. The
Contributor shall also provide (or cause Merit to provide) to the Company's
representatives an original of the signed representation letter which has been
approved by the Transferee's accountants.
                                                                         
                  (g)    The Contributor shall, and shall cause any other person
designated by it to receive OP Units and/or Company Warrants to, execute and
deliver to the Operating Partnership and/or the Company at or prior to Closing
a certificate in a form reasonably satisfactory to the Transferee (the
"INVESTOR CERTIFICATE") to the effect that each such person (a) is acquiring
the OP Units or Company Warrants being acquired hereunder for investment (for
its own account or for accounts over which it exercises investment control),
and not with a view to, or for offer or sale in connection with, any
distribution thereof that would be in violation of the Securities Act of 1933,
as amended (the "1933 ACT"), without prejudice, however, to such person's right
at all times to sell or otherwise dispose of all or any part of such OP Units
or Company Warrants pursuant to an effective registration statement under the
1933 Act, or under an exemption from such registration available under the 1933
Act, (b) is knowledgeable, sophisticated and experienced in business and
financial matters and fully understands the limitations on transfer described
above and (c) is an "accredited investor" as such term is defined in Rule
501(a) of Regulation D under the 1933 Act.

                  (h)    Notwithstanding anything to the contrary provided in
this Section 6.1 or any other provision of this Agreement, (i) the Transferee
agrees that the Contributor shall have the right, without the consent of the
Transferee, to (x) amend the Purchase Agreements to accelerate the



                                       9

<PAGE>   15


"Closing Date" under and defined in the Purchase Agreements to a date no
earlier than September 30, 1997 or later than October 15, 1997, and (y) waive
the estoppel conditions set forth in Paragraphs 6(b) of the Purchase Agreements
provided that the Contributor receives from Merit tenant estoppel certificates
reasonably satisfactory to the Transferee and its lender from tenants occupying
the Property paying in the aggregate at least eighty percent (80%) of the gross
rental income being generated by the Property as well as from the nine (9)
largest tenants based on gross rental payments made relating to the Property,
and (ii) if the Transferee fails to respond in writing with respect to any
written request, by the Contributor for the Transferee's consent under this
Section 6.1 within one (1) business day after such request (or in the event
that such issue arises within one (1) business day of the Closing, prior to
Closing), the Transferee shall be deemed to have approved such matter, and
(iii) in the event that the Transferee has the right to approve any matter
under this Section 6.1 and timely disapproves a request for its approval, the
Contributor shall nonetheless be entitled to take the action with respect to
which such request for approval has been made despite the Transferee's
disapproval, provided that, if the Contributor takes such an action
notwithstanding the Transferee's disapproval thereof, the Transferee shall have
the right to terminate this Agreement by delivering written notice of
termination to the Contributor within one (1) business day after the
Contributor notifies the Transferee in writing that the Contributor has taken
such action (or, in the event that such issue arises within one (1) business
day of the Closing, prior to the Closing). In the event that the Transferee
terminates this Agreement pursuant to the immediately preceding proviso, the
Contributor shall have the right in its sole and absolute discretion to proceed
with the consummation of all or any of the transactions described in the
Purchase Agreements, free of any claims by the Transferee with respect to the
Property, and the Contributor may retain any Extension Fee, provided however,
if the Transferee promptly returns all of the Inspection Materials to the
Contributor and is not in otherwise in default hereunder (including, without
limitation, by unreasonably withholding approval), the Earnest Money shall be
immediately returned to the Transferee. In the event that the Transferee fails
to deliver written notice of termination within such one (1) business day
period (or, in the event that such issue arises within one (1) business day of
the Closing, prior to Closing), the Transferee shall be deemed to have approved
such matter and waived such right of termination, and in all events the
occurrence of the Closing shall constitute the Transferee's approval of such
matter and waiver of such applicable termination right.

         Section 6.2     Registration Rights. The Company has, or promptly after
demand by the Contributor Parties under the Registration Rights Agreement (as
defined below), the Company shall cause to be, filed with the SEC a
registration statement and related prospectus that comply in all material
respects with applicable SEC rules providing for registration under the 1933
Act of the public offer and sale by the Contributor Parties of the Shares. The
Company shall use its best efforts to cause such registration statement to be
declared effective by the SEC as soon as practicable and to keep such
registration effective thereafter for the period specified in the Registration
Rights Agreement. The Company and each of the Contributor Parties shall enter
into a registration rights agreement (the "REGISTRATION RIGHTS AGREEMENT"),
substantially in the form of Exhibit 6.2, on or prior to the Closing Date,
providing for, among other things, the registration of the total number of
Shares that each of the Contributor Parties would own if it were to convert all
OP Units owned by it.

         Section 6.3     Confidentiality. Except as hereinafter provided, from
and after the execution of this Agreement until the Closing, the Transferee and
the Contributor shall abide by the confidentiality provisions of the Purchase
Agreements and shall keep the terms, conditions and provisions of this
Agreement confidential and neither shall make any public announcements hereof
unless the other first approves of same in writing, nor shall either disclose
the terms, conditions and provisions hereof, except to their respective
employees, agents, partners, investors, attorneys, accountants, engineers,
surveyors, financiers and bankers. The Contributor acknowledges and agrees that
the Transferee is a public company and as such will be required pursuant to the
rules and regulations of the SEC to disclose the terms of this Agreement and
the transactions contemplated herein. Notwithstanding the foregoing, in
connection with the performance of its obligations under Section 6.2 and under
the Registration Rights Agreement, the Transferee will have the absolute right
to prepare and file all necessary or required registration statements and other
papers, documents and instruments necessary or required in Transferee's
judgment and that of its attorneys and underwriters to file a registration
statement with respect to the Shares with the SEC and/or similar state
authorities and to cause same to become effective and to disclose therein and
thus to its underwriters, to the SEC and/or to similar state authorities and to
the public all of the terms, conditions and provisions of this Agreement. The
obligations of this Section 6.3 shall survive any termination of this
Agreement.                                                                     

         Section 6.4     Cooperation. Subject to the terms and conditions herein
provided and without additional cost or expense, the parties to this Agreement
shall use commercially reasonable efforts to take, or cause to be taken, all
other actions and do, or cause to be done, all other things necessary, proper
or appropriate to consummate and make effective the transactions contemplated
by this Agreement pursuant to their respective rights and obligations
hereunder. If, at any time after the Closing Date, any further action is
reasonably necessary or desirable to further carry out the purposes of this
Agreement, the proper officers and directors and other duly authorized
representatives of the parties shall take all such necessary action (provided
that no such requested action shall increase the applicable party's obligations
or liabilities hereunder or result in any additional cost or expense).

 Agreement.

                  (a)    The representations and warranties made by the

the Contributor hereunder so long as such matters do not have a material adverse
effect on the transactions contemplated herein.                         

                  (b)    The Operating Partnership and the Company shall have

conveyance of the Purchase Agreements and the Operating Partnership's and the

Company):

                  (a)    The representations and warranties made by the

ARTICLE 9.        ASSIGNMENT.

         No party may assign this Agreement or any interest therein to any
other person without the prior written consent of the other parties hereto,
provided that the Transferee acknowledges and consents to the Contributor
acting on behalf of the Contributor Parties hereunder.

ARTICLE 10.       BROKERS/COMMISSIONS.

         The Contributor and the Transferee covenant and agree one with the
other that no real estate commissions, finders' fees or brokers' fees have been
or will be incurred in connection with this Agreement or the transaction
contemplated hereby except for certain commissions payable by the



                                       14

<PAGE>   20



Company to Prudential Securities Incorporated (the "BROKER"), as to which the
Company will indemnify, defend and hold harmless the Contributor from and
against any claim asserted by the Broker for any commissions, finders' fees or
brokers' fees or other compensation claimed to be due broker in connection with
the transactions contemplated by this Agreement. Except for any amount payable
by the Company to the Broker, the Contributor and the Transferee shall
indemnify, defend and hold each other harmless from and against any claims,
liabilities, obligations or damages for commissions, finders' or brokers' fees
resulting from or arising out of the Transferee's acquisition of the Property
or the transactions contemplated hereby, asserted against either party by any
broker or other person claiming by, through or under the indemnifying party or
whose claim is based on the indemnifying party's acts or omissions. The
provisions of this Article 10 shall survive the Closing or other termination of
this Agreement.

ARTICLE 11.       DEFAULT/REMEDIES.

         Section 11.1    Mutual Termination/Termination by Transferee. The
Contributor and the Transferee may terminate this Agreement at any time prior
to Closing by mutual written agreement. Either the Transferee or the
Contributor may terminate this Agreement at any time prior to Closing upon a
material failure of any condition set forth in Section 8.2. Upon a termination
of this Agreement in its entirety under this Section 11.1, all Inspections
Materials shall be promptly returned to the Contributor, the Earnest Money
shall be immediately returned to the Transferee, and neither the Contributor
nor the Transferee shall have any further rights or obligations hereunder,
except for such rights and obligations which survive termination.
Notwithstanding the preceding sentence, if the failure of a condition set forth
in Section 8.2 was caused by a default by the Contributor, the Transferee may,
at its option, exercise its rights and remedies under Section 11.3.

         Section 11.2    Default by the Transferee. In the event that the
transaction contemplated by this Agreement does not close on or prior to the
Closing Date by reason of the failure of a condition set forth in Section 8.1
the Contributor may, as its sole and exclusive remedy (except as otherwise set
forth in this Section 11.2), terminate this Agreement by written notice to the
Transferee and the Title Company shall immediately deliver to the Contributor
the Earnest Money. In such event, the Contributor may recover the Earnest Money
as liquidated damages and not as a penalty. The Contributor and the Transferee
have agreed that such amount is a reasonable estimate of the damages that the
Contributor would be likely to sustain in the event of the Transferee's
default, as the actual amount of such damages would be difficult or
impracticable to determine. In addition to the foregoing, in the event that (i)
the transaction contemplated by this Agreement does not close on or prior to
the Closing Date by reason of the failure of a condition set forth in Section
8.1 caused by the Transferee and (ii) Merit terminates the Purchase Agreements
as a result of a default by the Contributor thereunder, the Company shall
immediately pay to the Contributor the Reimbursement Amount. Nothing contained
in this Section 11.2 shall limit or impair any of the provisions of Section
6.3, Article 10, Section 13.11, Section 13.13 and the obligations of Transferee
set forth in this Agreement to return the Inspection Materials upon termination
of this Agreement.

         Section 11.3    Default by Contributor. In the event that the
transaction contemplated by this Agreement does not close on or prior to the
Closing Date by reason of the failure of a condition set forth in Section 8.2
that was caused by a default by the Contributor hereunder, the Transferee may,
at its option, exercise any one or more of the following remedies as its sole
and exclusive remedies: (a) terminate this Agreement in its entirety by written
notice to the Contributor, and obtain an immediate refund of the Earnest Money;
or (b) solely in the event that Merit proceeds to close the transactions under
the Purchase Agreements and the Contributor willfully refuses to consummate the
transactions hereunder, to enforce specific performance of this Agreement.

ARTICLE 12.       NOTICE.

         All notices, demands, requests, or other writings in this Agreement
provided to be given, made or sent, or which may be given, made or sent, by

                                       17

<PAGE>   23

("Assignee").

                                  RECITALS

        WHEREAS, Assignor, acting on the behalf of Shidler West Acquisition
Company, LLC and AG Industrial Investors, L.P. (collectively, the "Contributor
Parties"), entered into, as "Purchaser," each of those certain Purchase
Agreements described on Schedule 1 attached thereto (collectively, the

        WHEREAS, Assignor and Assignee entered into that certain Contribution
and Exchange Agreement dated as of September 25, 1997 (the "Contribution

        WHEREAS, pursuant to Paragraph 17(c) of each of the Purchase

       SECTION 3.1   PURPOSE AND BUSINESS.

       The purpose and nature of the business to be conducted by the
Partnership is (i) to acquire, own, develop, improve, lease, manage, operate,
finance, refinance, transfer, sell or otherwise dispose of the Property;
provided, however, that such activities shall be limited to and conducted in

REIT for any reason or reasons not related to the business conducted by the
Partnership; (ii) to enter into any corporation, partnership, joint venture or
limited liability company to engage in any of the foregoing or the ownership of
interests in any entity engaged directly in any of the foregoing; and (iii) to

sole discretion to cease qualifying as a REIT, the Partners acknowledge that

Partners and not solely the General Partner or its Affiliates.

Except as provided in Section 10.5 hereof, the Partners shall have no
obligation to make any additional Capital Contributions or provide any
additional funding to the Partnership (whether in the form of loans, repayments
of loans or otherwise). No Partner shall have any obligation to restore any
deficit that may exist in its Capital Account, either upon a liquidation of the

discretion of the General Partner.

       SECTION 4.4   OTHER CONTRIBUTION PROVISIONS.

       In the event that any Partner is admitted to the Partnership and is
given a Capital Account in exchange for services rendered to the Partnership,
such transaction shall be treated by the Partnership and the affected Partner
as if the Partnership had compensated such Partner in cash, and the Partner had
contributed such cash to the capital of the Partnership, unless the General
Partner and such affected Partner specifically agree otherwise.

       SECTION 4.5   NO INTEREST ON CAPITAL.

       Except as otherwise expressly set forth herein, no Partner shall be
entitled to interest on its Capital Contributions or its Capital Account.

consent of each Limited Partner, the General Partner may not admit any
additional Partners other than such Substituted Limited Partners as shall be

the sale or other taxable disposition of any Partnership asset shall, to the
extent possible after taking into account other required allocations of gain

may make such a modification; provided that such modification is reasonably
consistent with the Partners' respective interests in the Partnership within
the meaning of Section 704(b) of the Code and the Treasury Regulations
thereunder.

Partners agrees that the General Partner is authorized to execute, deliver and
perform the above-mentioned agreements and transactions on behalf of the
Partnership without any further act, approval or vote of the Partners,
notwithstanding any other provision of this Agreement (except as expressly
provided to the contrary in Section 7.3), the Act or any applicable law, rule
or regulation, to the full extent permitted under the Act or other applicable
law. The good faith execution, delivery or performance by the General Partner
or the Partnership of any agreement authorized or permitted under this
Agreement shall not constitute a breach by the General Partner of any duty that
the General Partner may owe the Partnership or the Limited Partners or any
other Persons under this Agreement or of any duty stated or implied by law or
equity.

              C.     INSURANCE.  At all times from and after the date hereof,

Indemnities hereunder and (iii) such other insurance as the General Partner, in
its reasonable discretion, determines to be necessary.

after the date hereof, the General Partner may cause the Partnership to

from time to time.





                                       22
<PAGE>   28
              E.     NO OBLIGATIONS TO CONSIDER TAX CONSEQUENCES OF LIMITED
PARTNERS.  In exercising its authority under this Agreement, the General
Partner may, but shall be under no obligation to, take into account the tax
consequences to any Partner (including the Limited Partners) of any action
taken (or not taken) by it. The General Partner and the Partnership shall not
have liability to any Limited Partner for monetary damages or otherwise for
losses sustained, liabilities incurred or benefits not derived by such Limited
Partner in connection with such decisions.

              F.     REOC STATUS.

                     (1)    The General Partner shall use good faith reasonable
efforts to conduct the affairs and operations of the Partnership in such a
manner that the Partnership will qualify as a "real estate operating company"
("REOC") within the meaning of 29 C.F.R. 2510.3-101(e), such that none of the
Partnership's assets would be deemed to be "plan assets" for purposes of ERISA.

                     (2)    The Partnership's first investment shall be in
"real estate" which the Partnership shall have the right to substantially
participate directly in the management or development activities thereof.

                     (3)    The Partnership shall, in the ordinary course of
its business, engage in the management or development of real estate.

                     (4)    The General Partner is hereby authorized to take
any action it has determined in good faith to be necessary or desirable in
order for (i) the Partnership not to be in violation of ERISA, (ii) the
Partnership to qualify as a REOC for purposes of ERISA, and (iii) the assets of
the Partnership not to be deemed "plan assets" of any ERISA entity which may
directly or indirectly invest in the Partnership, including, but not limited
to, making structural, operating or other changes in the Partnership, and
making structural or other changes in any Partnership investment; provided
however, the General Partner shall under no circumstances be required to take
any action hereunder which may adversely affect the status of the General
Partner as a REIT, or result in the violation of applicable provisions of
federal or state securities laws.  Under no circumstances shall the General
Partner have any liability to the Partnership or any Partner for any action or
any failure to take any action which results in the Partnership failing to
qualify as a REOC, a violation of ERISA or the assets of the Partnership
constituting "plan assets" for purposes of ERISA.

       SECTION 7.2   CERTIFICATE OF LIMITED PARTNERSHIP.

       The General Partner shall use all reasonable efforts to cause to be
filed a Certificate of Limited Partnership and such certificates or documents
as may be reasonable and necessary or appropriate for the formation,
qualification and operation of a limited partnership (or a partnership in which
the limited partners have limited liability) in the State of Delaware and any
other state, the District of Columbia or other jurisdiction in which the
Partnership may elect to do business or own property. To the extent that such
action is determined by the General Partner to be reasonable and necessary or
appropriate, the General Partner shall file amendments to and restatements of
the





                                       23
<PAGE>   29
Certificate and do all the things to maintain the Partnership as a limited
partnership (or a partnership in which the limited partners have limited
liability) under the laws of the State of Delaware and each other state, the
District of Columbia or other jurisdiction in which the Partnership may elect
to do business or own property.  The General Partner shall not be required,
before or after filing, to deliver or mail a copy of the Certificate or any
amendment thereto to any Limited Partner.

       SECTION 7.3   RESTRICTIONS ON GENERAL PARTNER'S AUTHORITY.

              A.     CONSENT REQUIRED.  The General Partner may not take any
action in contravention of an express prohibition or limitation of this
Agreement or any action that reasonably could be expected to cause the
Partnership not to qualify as a "partnership" for federal income tax purposes
without the written Consent of all of the Limited Partners (which consent may
be given, conditioned or withheld in each such Limited Partner's sole and
absolute discretion) or (ii) such lower percentage of the Limited Partner
Interests as may be specifically provided for under a provision of this
Agreement or the Act.

              B.     SALE OR PROPERTY.  Except as provided in Article XIII
hereof, the General Partner may not sell, exchange, transfer or otherwise
dispose of the Property at any time before   October 3, 1999, without the prior
written consent of all of the Limited Partners, which consent may be given,
conditioned or withheld in each such Limited Partner's sole and absolute
discretion. Notwithstanding any provision herein to the contrary, the General
Partner shall have complete authority, acting singly and without the necessity
of joinder of any other Person, to sell, exchange, transfer or otherwise
dispose of all or any portion of the Property (including a transfer of such
Property pursuant to a merger) (i) at any time on or after October 3, 1999 as
long as the acquiror of the Property is not the General Partner or any
Affiliate thereof; (ii) at any time on or after October 3, 2003 to any Person
(subject to the provisions of Section 7.3.E hereof); and (iii) at any time in a
transaction that pursuant to a nonrecognition provision in the Code does not
result in current recognition of any gain by any Limited Partner (including
without limitation the contribution of the Property to a wholly-owned
corporation under Code Section 351, the contribution of the Property to a
partnership under Code Section 721 and the exchange of the Property for like-
kind property under Code Section 1031, provided that in the event of any such
like-kind exchange, the acquired property shall be subject to the same
restrictions herein as if such acquired property were the original Property
hereunder).  Notwithstanding any provision to the contrary herein, the General
Partner shall not distribute the Property or any portion thereof, to the
Limited Partners if such distribution would result in any tax liability under
Section 737 of the Code prior to October 3,  1999, without the prior written
consent of all of the Limited Partners, which consent may be given, conditioned
or withheld in each Limited Partner's sole and absolute discretion.

              C.     DISSOLUTION.  The General Partner shall not voluntarily
take any action that  would cause, result in or lead to the dissolution of the
Partnership prior to October 3, 2003, without the prior written consent of all
of the Limited Partners, which consent may be given, conditioned or withheld in
each Limited Partner's sole and absolute discretion; provided that the
foregoing provision shall not limit the General Partner's ability to sell,
exchange, transfer or otherwise dispose of the Property to a Person other than
the General Partner or an Affiliate of the General Partner at





                                       24
<PAGE>   30
any time after October 3, 1999 and to distribute the proceeds therefrom in
liquidation of the Partnership under Article XIII.

              D.     TYPES OF FINANCING. For all fiscal periods of the
Partnership prior to October 3, 1999, (i) the General Partner shall use its
good faith reasonable efforts to ensure that the Partnership does not operate
in a manner which results in income allocable to the Limited Partners being
characterized as "unrelated debt-financed income" within the meaning of Section
514 of the Code; and (ii) the General Partner shall use its good faith
reasonable efforts to ensure that the Partnership minimizes the amount of any
"unrelated business taxable income" which it recognizes within the meaning of
Section 512 of the Code.  For purposes of this Section 7.3.D, the General
Partner and each Limited Partner acknowledges that the determination regarding
whether the Partnership has "unrelated debt financed income" is highly complex;
and further, each Partner acknowledges and agrees that in fulfilling its duties
under this Section 7.3.D, the General Partner may assume, without any further
duty to inquire, that (i) any non-profit organization which owns an interest in
the Partnership is a qualified trust within the meaning of Section 401(a) of
the Code, (ii) any and all preferred returns payable to Limited Partners
hereunder are reasonable preferred returns within the meaning of Section
514(c)(9)(E) of the Code and all profit and loss allocations as expressly
provided herein shall satisfy the "fractions rule" under Section 514 of the
Code.  Under no circumstances shall the General Partner have any liability to
the Partnership or any Partner for any action (including without limitation
taking any and all such action as may be necessary in connection with obtaining
that certain loan in the principal sum of $20,675,000.00 from Prudential
Securities Credit Corporation, a Delaware corporation) or failure to take any
action which results in any income of the Partnership being characterized as
"unrelated business taxable income" under Section 512 of the Code or "unrelated
debt-financed income" under Section 514 of the Code.

              E.     AFFILIATED TRANSACTIONS.  The General Partner shall not
cause the Partnership to enter into any transaction with the General Partner or
any Affiliate of the General Partner unless the material terms and conditions
of such transactions are commercially reasonable as determined by the General
Partner in its reasonable discretion.

       SECTION 7.4   REIMBURSEMENT OF THE GENERAL PARTNER.

              A.     NO COMPENSATION.  Except as provided in this Section 7.4
and elsewhere in this Agreement (including the provisions of Articles V and VI
hereof regarding distributions, payments and allocations to which it may be
entitled), the General Partner shall not be compensated for its services as
general partner of the Partnership.

              B.     RESPONSIBILITY FOR PARTNERSHIP EXPENSES.  The Partnership
shall be responsible for and shall pay all expenses relating to the
Partnership's organization, the ownership of its assets and its operations. The
General Partner shall be reimbursed on a monthly basis, or such other basis as
the General Partner may determine in its good faith discretion, for all
expenses it, and/or its Affiliates incur relating to the operation of, or for
the benefit of, the Partnership. The General Partner shall reasonably determine
the amount of expenses incurred by the General Partner and its Affiliates
related to the operation of, or for the benefit of, the Partnership.  In the
event that





                                       25
<PAGE>   31
certain expenses are incurred for the benefit of both the Partnership and other
entities (including the General Partner or any of its Affiliates), such
expenses will be allocated to the Partnership and such other entities in a fair
and reasonable manner.  Such reimbursements shall be in addition to any
reimbursement to the General Partner, and/or its Affiliates pursuant to Section
10.3.C hereof and as a result of indemnification pursuant to Section 7.6 below.
All payments and reimbursements hereunder shall be characterized for federal
income tax purposes as expenses of the Partnership incurred on its behalf, and
not as expenses of the General Partner, and/or its Affiliates.

              C.     REIMBURSEMENT NOT A DISTRIBUTION.  If and to the extent
any reimbursement made pursuant to this Section 7.4 is determined for federal
income tax purposes not to constitute a payment of expenses of the Partnership,
the amount so determined shall constitute a guaranteed payment under Section
707 of the Code, shall be treated consistently therewith by the Partnership and
all Partners and shall not be treated as a distribution for purposes of
computing the Partners' Capital Accounts.

       SECTION 7.5   OUTSIDE ACTIVITIES OF THE GENERAL PARTNER.

              The General Partner shall devote to the Partnership such time as
may be necessary for the proper performance of its duties as General Partner,
but the General Partner is not required, and is not expected, to devote its
full time to the performance of such duties.  It is understood that the General
Partner, and its officers, directors, employees, agents, trustees, Affiliates,
Subsidiaries and shareholders shall have substantial business interests and
engage in substantial business activities in addition to those relating to the
Partnership, including, without limitation, engaging in other business
interests and activities which are in direct or indirect competition with the
Partnership.  Neither the Partnership nor any Partners shall have any right by
virtue of this Agreement or the partnership relationship established hereby in
or to such other ventures or activities or to the income or proceeds derived
therefrom, and the pursuit of such ventures, even if directly competitive with
the business of the Partnership, shall not be deemed wrongful or improper in
any manner.  Neither the General Partner nor any Affiliate of the General
Partner shall be obligated to present any particular opportunity to the
Partnership even if such opportunity is of a character which, if presented to
the Partnership, could be taken by the Partnership, and, regardless of whether
or not such opportunity is competitive with the Partnership. The General
Partner, and any Affiliate of the General Partner shall have the right to take
for its own account (individually or as a shareholder, member, trustee, partner
or fiduciary), or to recommend to others, any such particular opportunity. The
General Partner, and its Affiliates may hold Limited Partner Interests and
shall be entitled to exercise all rights of a Limited Partner relating to such
Limited Partner Interests.

       SECTION 7.6   INDEMNIFICATION.

              A.     GENERAL.  THE PARTNERSHIP SHALL INDEMNIFY EACH INDEMNITEE
FROM AND AGAINST ANY AND ALL LOSSES, CLAIMS, DAMAGES, LIABILITIES, JOINT OR
SEVERAL, EXPENSES (INCLUDING, WITHOUT LIMITATION, ATTORNEYS' FEES AND OTHER
LEGAL FEES AND EXPENSES), JUDGMENTS, FINES, SETTLEMENTS AND OTHER AMOUNTS
ARISING FROM OR





                                       26
<PAGE>   32
IN CONNECTION WITH ANY AND ALL CLAIMS, DEMANDS, ACTIONS, SUITS OR PROCEEDINGS,
CIVIL, CRIMINAL, ADMINISTRATIVE OR INVESTIGATIVE INCURRED BY THE INDEMNITEE AND
RELATING TO THE PARTNERSHIP, OR ITS OPERATIONS, AS SET FORTH IN THIS AGREEMENT,
IN WHICH ANY SUCH INDEMNITEE MAY BE INVOLVED, OR IS THREATENED TO BE INVOLVED,
AS A PARTY OR OTHERWISE, UNLESS IT IS ESTABLISHED BY A FINAL DETERMINATION OF A
COURT OF COMPETENT JURISDICTION THAT: (I) THE ACT OR OMISSION OF THE INDEMNITEE
WAS MATERIAL TO THE MATTER GIVING RISE TO THE PROCEEDING AND EITHER WAS
COMMITTED IN BAD FAITH WAS THE RESULT OF ACTIVE AND DELIBERATE DISHONESTY, OR
CONSTITUTES GROSS NEGLIGENCE OR WILLFUL MISCONDUCT, (II) THE INDEMNITEE
ACTUALLY RECEIVED AN IMPROPER PERSONAL BENEFIT IN MONEY, PROPERTY OR SERVICES
OR (III) IN THE CASE OF ANY CRIMINAL PROCEEDING, THE INDEMNITEE HAD REASONABLE
CAUSE TO BELIEVE THAT THE ACT OR OMISSION WAS UNLAWFUL. WITHOUT LIMITATION, THE
FOREGOING INDEMNITY SHALL EXTEND TO ANY LIABILITY OF ANY INDEMNITEE, PURSUANT
TO A LOAN GUARANTEE, CONTRACTUAL OBLIGATIONS FOR ANY INDEBTEDNESS OR OTHER
OBLIGATIONS OR OTHERWISE, FOR ANY INDEBTEDNESS OF THE PARTNERSHIP OR ANY
SUBSIDIARY OF THE PARTNERSHIP (INCLUDING, WITHOUT LIMITATION, ANY INDEBTEDNESS
WHICH THE PARTNERSHIP OR ANY SUBSIDIARY OF THE PARTNERSHIP HAS ASSUMED OR TAKEN
SUBJECT TO), AND THE GENERAL PARTNER IS HEREBY AUTHORIZED AND EMPOWERED, ON
BEHALF OF THE PARTNERSHIP, TO ENTER INTO ONE OR MORE INDEMNITY AGREEMENTS
CONSISTENT WITH THE PROVISIONS OF THIS SECTION 7.6.A IN FAVOR OF ANY INDEMNITEE
HAVING OR POTENTIALLY HAVING LIABILITY FOR ANY SUCH INDEBTEDNESS. THE
TERMINATION OF ANY PROCEEDING BY JUDGMENT, ORDER OR SETTLEMENT DOES NOT CREATE
A PRESUMPTION THAT THE INDEMNITEE DID NOT MEET THE REQUISITE STANDARD OF
CONDUCT SET FORTH IN THIS SECTION 7.6.A. THE TERMINATION OF ANY PROCEEDING BY
CRIMINAL CONVICTION OR UPON A PLEA OF NOLO CONTENDERE OR ITS EQUIVALENT, OR AN
ENTRY OF AN ORDER OF PROBATION PRIOR TO JUDGMENT, CREATES A REBUTTABLE
PRESUMPTION THAT THE INDEMNITEE ACTED IN A MANNER CONTRARY TO THAT SPECIFIED IN
THIS SECTION 7.6.A WITH RESPECT TO THE SUBJECT MATTER OF SUCH PROCEEDING. ANY
INDEMNIFICATION PURSUANT TO THIS SECTION 7.6.A SHALL BE MADE ONLY OUT OF THE
ASSETS OF THE PARTNERSHIP, AND ANY INSURANCE PROCEEDS FROM THE LIABILITY POLICY
COVERING THE GENERAL PARTNER AND ANY INDEMNITIES, AND NEITHER THE GENERAL
PARTNER NOR ANY LIMITED PARTNER SHALL HAVE ANY OBLIGATION TO CONTRIBUTE TO THE
CAPITAL OF THE PARTNERSHIP OR OTHERWISE PROVIDE FUNDS TO ENABLE THE PARTNERSHIP
TO FUND ITS OBLIGATIONS UNDER THIS SECTION 7.6.A.

              B.     ADVANCEMENT OF EXPENSES.  Reasonable expenses expected to
be incurred by an Indemnitee shall be paid or reimbursed by the Partnership in
advance of the final disposition





                                       27
<PAGE>   33
of any and all claims, demands, actions, suits or proceedings, civil, criminal,
administrative or investigative made or threatened against an Indemnitee upon
receipt by the Partnership of (i) a written affirmation by the Indemnitee of
the Indemnitee's good faith belief that the standard of conduct necessary for
indemnification by the Partnership as authorized in Section 7.6.A has been met
and (ii) a written undertaking by or on behalf of the Indemnitee to repay the
amount if it shall ultimately be determined that the standard of conduct has
not been met and provides reasonable security therefor.

              C.     NO LIMITATION OF RIGHTS.  The indemnification provided by
this Section 7.6 shall be in addition to any other rights to which an
Indemnitee or any other Person may be entitled under any agreement, pursuant to
any vote of the Partners, as a matter of law or otherwise, and shall continue
as to an Indemnitee who has ceased to serve in such capacity unless otherwise
provided in a written agreement pursuant to which such Indemnitee is
indemnified.

              D.     INSURANCE.  The Partnership may purchase and maintain
insurance on behalf of the Indemnities and such other Persons as the General
Partner shall determine against any liability that may be asserted against or
expenses that may be incurred by such Persons in connection with the
Partnership's activities, regardless of whether the Partnership would have the
power to indemnify such Persons against such liability under the provisions of
this Agreement.

              E.     NO PERSONAL LIABILITY FOR LIMITED PARTNERS.  In no event
may an Indemnitee subject any of the Partners to personal liability by reason
of the indemnification provisions set forth in this Agreement.  Notwithstanding
anything to the contrary contained herein, no member, manager, employee,
director, officer, agent, partner or shareholder of any Limited Partner shall
have any liability or obligation of any kind or nature whatsoever under this
agreement.

              F.     INTERESTED TRANSACTIONS.  An Indemnitee shall not be
denied indemnification in whole or in part under this Section 7.6 because the
Indemnitee had an interest in the transaction with respect to which the
indemnification applies if the transaction was otherwise permitted by the terms
of this Agreement.

              G.     BENEFIT. The provisions of this Section 7.6 are for the
benefit of the Indemnities, their heirs, successors, assigns and administrators
and shall not be deemed to create any rights for the benefit of any other
Persons. Any amendment, modification or repeal of this Section 7.6, or any
provision hereof, shall be prospective only and shall not in any way affect the
Partnership's obligation to any Indemnitee under this Section 7.6 as in effect
immediately prior to such amendment, modification or repeal with respect to
claims arising from or related to matters occurring, in whole or in part, prior
to such amendment, modification or repeal, regardless of when such claims may
arise or be asserted.

              H.     INDEMNIFICATION PAYMENTS NOT DISTRIBUTIONS.  If and to the
extent any payments to any Partner pursuant to this Section 7.6 constitute
gross income to such Partner (as opposed to the repayment of advances made on
behalf of the Partnership), such amounts shall constitute guaranteed payments
within the meaning of Section 707(c) of the Code, shall be treated





                                       28
<PAGE>   34
consistently therewith by the Partnership and all Partners, and shall not be
treated as distributions for purposes of computing the Partners' Capital
Accounts.

       SECTION 7.7   LIABILITY OF THE GENERAL PARTNER.

              A.     GENERAL.  Notwithstanding anything to the contrary set
forth in this Agreement, neither the General Partner, nor the trustees,
directors and officers of the General Partner, or any Affiliate of the General
Partner, shall be liable for monetary damages to the Partnership, any Partners
or any Assignees for losses sustained, liabilities incurred or benefits not
derived as a result of errors in judgment or mistakes of fact or law or of any
act or omission if the General Partner acted in good faith and such action did
not constitute gross negligence or willful misconduct.

              B.     NO OBLIGATION TO CONSIDER SEPARATE INTERESTS OF LIMITED
PARTNERS OR SHAREHOLDERS. The Limited Partners expressly acknowledge that the
General Partner is acting on behalf of the Partnership, and the shareholders of
the General Partner collectively, that the General Partner is under no
obligation to consider the separate interests of the Limited Partners
(including, without limitation, the tax consequences to Limited Partners or
Assignees) in deciding whether to cause the Partnership to take (or decline to
take) any actions permitted under this agreement and that neither of the
General Partner, nor any of its Affiliates, shall be liable for monetary
damages or otherwise for losses sustained, liabilities incurred or benefits not
derived by Limited Partners in connection with such decisions, provided that
the General Partner has acted in good faith and in accordance with the terms of
this Agreement.

              C.     ACTIONS OF AGENTS. The General Partner may exercise any of
the powers granted to it by this Agreement and perform any of the duties
imposed upon it hereunder either directly or by or through its agents. Neither
of the General Partner, nor any of its Affiliates, shall be responsible for any
misconduct or negligence on the part of any such agent appointed by the General
Partner in good faith.

              D.     EFFECT OF AMENDMENT.  Any amendment, modification or
repeal of this Section 7.7 or any provision hereof shall be prospective only
and shall not in any way affect the limitations on the liability of the General
Partner, or any Affiliate of the General Partner, to the Partnership and the
Limited Partners under this Section 7.7 as in effect immediately prior to such
amendment, modification or repeal with respect to claims arising from or
relating to matters occurring, in whole or in part, prior to such amendment,
modification or repeal, regardless of when such claims may arise or be
asserted.

      SECTION 7.8   OTHER MATTERS CONCERNING THE GENERAL PARTNER.

             A.     RELIANCE ON DOCUMENTS. The General Partner may rely and
shall be protected in acting or refraining from acting upon any resolution,
certificate, statement, instrument, opinion, report, notice, request, consent,
order, bond, debenture or other paper or document believed by it in good faith
to be genuine and to have been signed or presented by the proper party or
parties.





                                       29

              B.     RELIANCE ON ADVISORS. The General Partner may consult with
legal counsel, accountants, appraisers, management consultants, investment
bankers, architects, engineers, environmental consultants and other consultants
and advisors selected by it, and any act taken or omitted to be taken in
reliance upon the opinion of such Persons as to matters which the General
Partner reasonably believes to be within such Persons' professional or expert
competence shall be conclusively presumed to have been done or omitted in good
faith and in accordance with such opinion.

              C.     ACTION THROUGH AGENTS. The General Partner shall have the
right, in respect of any of its powers or obligations hereunder, to act through
any of its duly authorized officers and a duly appointed attorney or
attorneys-in-fact. Each such attorney shall, to the extent provided by the
General Partner in the power of attorney, have full power and authority to do
and perform each and every act and duty which is permitted or required to be
done by the General Partner hereunder.

              D.     ACTIONS TO MAINTAIN REIT STATUS OR AVOID TAXATION OF THE
GENERAL PARTNER. Notwithstanding any other provisions of this Agreement or the
Act, any action of the General Partner on behalf of the Partnership or any
decision of the General Partner to refrain from acting on behalf of the
Partnership undertaken in the good faith belief that such action or omission is
necessary or advisable in order (i) to protect the ability of the General
Partner to continue to qualify as a REIT or (ii) to allow the General Partner
to avoid incurring any liability for taxes under Section 857 or 4981 of the
Code, is expressly authorized under this Agreement.

       SECTION 7.9   TITLE TO PARTNERSHIP ASSETS.

       Title to Partnership assets, whether real, personal or mixed and whether
tangible or intangible, shall be deemed to be owned by the Partnership as an
entity, and no Partner, individually or collectively, shall have any ownership
interest in such Partnership assets or any portion thereof.

       SECTION 7.10  RELIANCE BY THIRD PARTIES.

       Notwithstanding anything to the contrary in this Agreement, any Person
dealing with the Partnership shall be entitled to assume that the General
Partner has full power and authority, without consent or approval of any other
Partner or Person, to encumber, sell or otherwise use in any manner any and all
assets of the Partnership, to enter into any contracts on behalf of the
Partnership and to take any and all actions on behalf of the Partnership, and
such Person shall be entitled to deal with the General Partner as if the
General Partner were the Partnership's sole party in interest, both legally and
beneficially. Each Limited Partner hereby waives any and all defenses or other
remedies which may be available against such Person to contest, negate or
disaffirm any action of the General Partner in connection with any such
dealing, provided that the foregoing, shall not otherwise limit or affect the
General Partner's liability to any Limited Partner hereunder in the event that
the General Partner willfully breaches any of its material obligations
hereunder. In no event shall any Person dealing with the General Partner or its
representatives be obligated to ascertain that the terms of this Agreement have
been complied with or to inquire into the necessity or expedience of any act or





                                       30
<PAGE>   36
action of the General Partner or its representatives. Each and every
certificate, document or other instrument executed on behalf of the Partnership
by the General Partner or its representatives shall be conclusive evidence in
favor of any and every Person relying thereon or claiming thereunder that (i)
at the time of the execution and delivery of such certificate, document or
instrument, this Agreement was in full force and effect, (ii) the Person
executing and delivering such certificate, document or instrument was duly
authorized and empowered to do so for and on behalf of the Partnership, and
(iii) such certificate, document or instrument was duly executed and delivered
in accordance with the terms and provisions of this Agreement and is binding
upon the Partnership.


                                 ARTICLE VIII.

                   RIGHTS AND OBLIGATIONS OF LIMITED PARTNERS

       SECTION 8.1   LIMITATION OF LIABILITY.

       Except as provided to the contrary in Sections 10.5 and 8.6, the Limited
Partners' liability under this Agreement shall be limited to the amount of
their Capital Contributions to the Partnership and provided that the foregoing
shall not limit SWIC's obligation to make the LP Capital Contribution to the
Partnership on behalf of the Limited Partners pursuant to the Contribution
Agreement and Section 4.1A.  Notwithstanding anything to the contrary herein,
no member, manager, employee, director, officer, agent, partner, or shareholder
of any Limited Partner shall have any liability or obligation of any kind or
nature whatsoever under this Agreement.

       SECTION 8.2   MANAGEMENT OF BUSINESS.

       No Limited Partner or Assignee (other than the General Partner, any of
its Affiliates or any trustee, officer, director, employee, partner, agent or
trustee of the General Partner, the Partnership or any of their Affiliates, in
their capacity as such) shall take part in the operation, management or control
(within the meaning of the Act) of the Partnership's business, transact any
business in the Partnership's name or have the power to sign documents for or
otherwise bind the Partnership.  The transaction of any such business by the
General Partner, any of its Affiliates or any trustee, officer, director,
employee, partner, agent or trustee of the General Partner, the Partnership or
any of their Affiliates, in their capacity as such, shall not affect, impair or
eliminate the limitations on the liability of the Limited Partners or Assignees
under this Agreement.

      SECTION 8.3   OUTSIDE ACTIVITIES OF LIMITED PARTNERS.

       Any Limited Partner and any trustee, officer, director, employee, agent,
trustee, Affiliate or shareholder of any Limited Partner shall be entitled to
and may have business interests and engage in business activities in addition
to those relating to the Partnership, including business interests and
activities in direct or indirect competition with the Partnership. Neither the
Partnership nor any Partners shall have any rights by





                                       31
<PAGE>   37
virtue of this Agreement in any business ventures of any Limited Partner or
Assignee. None of the Limited Partners nor any other Person shall have any
rights by virtue of this Agreement or the partnership relationship established
hereby in any business ventures of any other Person, and such Person shall have
no obligation pursuant to this Agreement to offer any interest in any such
business ventures to the Partnership, any Limited Partner or any such other
Person, even if such opportunity is of a character which, if presented to the
Partnership, any Limited  Partner or such other Person, could be taken by such
Partnership, Limited Partner or Person.

       SECTION 8.4   RETURN OF CAPITAL.

       No Limited Partner shall be entitled to the withdrawal or return of its

this Agreement or upon termination of the Partnership as provided herein.
Except to the extent expressly provided to the contrary by Exhibit C hereto or
as permitted by Sections 5.1., 6.1 and 13.2 hereof or otherwise expressly
provided in this Agreement, no Limited Partner or Assignee shall have priority
over any other Partner or Assignee either as to the return of Capital
Contributions or as to profits, losses, distributions or credits.

       SECTION 8.5   RIGHTS OF LIMITED PARTNERS RELATING TO THE PARTNERSHIP.

       A.     GENERAL.  In addition to other rights provided by this Agreement
or by the Act, each Limited Partner shall have the right, for a purpose
reasonably related to such Limited Partner's Partnership Interest, upon written
demand with a statement of the purpose of such demand and at such Limited
Partner's own expense:

              (1)    to obtain a copy of the Partnership's federal, state and
local income tax returns for each Partnership Year; and

              (2)    to obtain a copy of this Agreement and the Certificate and
all amendments thereto.

       SECTION 8.6   PUT RIGHT.

       A.     GENERAL.

              (1)    Subject to Section 8.6.C below, on or after October 3,
1999 (as such date may be accelerated pursuant to subparagraph (4) below) each
Limited Partner shall have the right (the "Put Right") to require the General
Partner to purchase all or a portion of the Partnership Units held by the
Limited Partner at a price equal to and in the form of the Consideration.  The
Put Right shall be exercised pursuant to a Put Notice delivered to the General
Partner by any such Limited Partner. No Limited Partner may exercise the Put
Right with regard to fewer than 100,000 Partnership Units; and provided that
with regard to the Partnership Units issued to AG hereunder, the holders
thereof (whether AG or any Assignee or transferee thereof) shall be limited to
exercising a total of two (2) separate Put Rights (counting in such limitation
any prior exercise of a Put Right by AG, or its Assignees or transferees), the
second of which must include all of such remaining Partnership Units, and with
regard to the Partnership Units issued to Shidler West hereunder, the holders
thereof (whether Shidler West or any Assignee or transferee thereof) shall be
limited to exercising a total





                                       32
<PAGE>   38
of two (2) separate Put Rights counting in such limitation any prior exercise
of a Put Right by Shidler West or its Assignees or transferees), the second of
which must include all of such remaining Partnership Units.

              (2)    A Limited Partner shall have no right with respect to any
interest in the Partnership Units specified in a Put Notice after providing
such Put Notice described above, other than the right to receive payment for
its interest in the Partnership in accordance with this Section 8.6.

              (3)    The Assignee of a Limited Partner may exercise the rights
of such Limited Partner pursuant to this Section 8.6, and such Limited Partner
shall be deemed to have assigned such rights to such Assignee and shall be
bound by the exercise of such rights by such Limited Partner's Assignee.   In
connection with any exercise of such rights by such Assignee on behalf of such
Limited Partner, the Consideration shall, upon prior written notice to the
General Partner, be paid by the General Partner directly to such Assignee and
not to such Limited Partner.

              (4)    Notwithstanding anything to the contrary provided herein
(including subparagraph (1) of this Section 8.6A), in the event of the complete
liquidation, dissolution or winding up of the General Partner (other than
pursuant to a transaction in which the Limited Partners are granted the right
to exercise their Put Rights with regard to the common shares of the acquiror
or successor in interest to the General Partner upon the same terms and
conditions as set forth herein, subject to any applicable Equity Adjustment),
whether pursuant to a tender offer, exchange offer or otherwise, the Limited
Partners shall have the immediate right to exercise their Put Rights hereunder.

       B.     PAYMENT OF CONSIDERATION.

              (1)    Within thirty (30) days of the delivery of the Put Notice
by a Limited Partner under this Section 8.6 the General Partner (subject to the
limitations set forth in Section 8.6C) shall transfer and deliver the
Consideration to such Limited Partner or, as applicable, its Assignee whereupon
the General Partner (or its designee) shall acquire the Partnership Units
offered by such Limited Partner or, as applicable, its Assignee and shall be
treated for all purposes of this Agreement as the owner of such Partnership
Units.

              (2)    In the event that the General Partner elects to pay the
Consideration to a Limited Partner in the form of the Share Consideration and
such Share Consideration is not a whole number of Shares, such Limited Partner
shall be paid (i) that number of Shares which equals the nearest whole number
less than such amount plus (ii) an amount of cash which the General Partner
reasonably determines, in its reasonable discretion, to represent the fair
value of the remaining fractional Share which would otherwise be payable to
such Limited Partner.

              (3)    Each exercising Limited Partner agrees to deliver to the
General Partner the Partnership Unit Certificate(s) representing the
Partnership Units identified in the Put Notice and to execute such documents as
the General Partner may reasonably require in connection with the issuance of
Shares upon exercise of the Put Right (including without limitation an
assignment of





                                       33
<PAGE>   39
Partnership Units pursuant to the terms of which such Limited Partner  agrees
to indemnify and hold General Partner harmless from any and all liens, claims
or encumbrances on such Partnership Units).

       C.     EXCEPTIONS TO EXERCISE OF PUT RIGHT.

       No Limited Partner shall be entitled to exercise the Put Right pursuant
to Section 8.6.A above if the delivery of Shares to such Limited Partner (a)
would be prohibited under the Declaration of Trust, as amended, of the General
Partner, (b) would adversely affect the ability of the General Partner to
continue to qualify as a REIT or subject the General Partner to any additional
taxes under Section 857 or Section 4981 of the Code, or (c) would be prohibited
under applicable federal or state securities laws or regulations.

       D.     NO LIENS ON PARTNERSHIP UNITS DELIVERED.

       Each exercising Limited Partner covenants and agrees with the General
Partner that all Partnership Units delivered in connection with the Put Right
shall be delivered to the General Partner, free and clear of all liens, claims
and encumbrances and, notwithstanding anything contained herein to the
contrary,  the General Partner shall not be under any obligation to acquire any
Limited Partner's Partnership Units, (1) to the extent that any such
Partnership Units are subject to any liens, claims or encumbrances, or (2) in
the event that such Limited Partner shall fail to give the General Partner
adequate assurances that such Partnership Units are not subject to any such
liens, claims or encumbrances or shall fail to agree to fully indemnify the
General Partner from any such liens, claims or encumbrances.  Each Limited
Partner further agrees that, in the event any state or local transfer tax is
payable as a result of the transfer of its Partnership Units to the General
Partner, such Limited Partner shall assume and pay such transfer tax.

       SECTION 8.7   NOTICE OF CERTAIN EVENTS.  In case at any time the General
Partner shall propose:

       A.     To fix a record date for the purpose of determining the holders
of Shares who are entitled to receive any dividend or distribution (other than
a regular periodic dividend or distribution payable in cash), or any right to
subscribe for, purchase or otherwise acquire any shares of beneficial interest
of any class or any other securities of the General Partner, or to receive any
other rights;

       B.     To effect any reorganization of the General Partner, any
reclassification or recapitalization of the shares of beneficial interest of
the General Partner or any cash tender offer (for more than 50% of the
outstanding Shares of the General Partner), consolidation, or merger involving
the General Partner and any other Person (pursuant to which the General Partner
is not the surviving entity) or any transfer of all or substantially all of the
assets of the Company to any other Person; or

       C.     To effect any liquidation, dissolution or winding up of the
General Partner or the Partnership then, and in any one or more of such cases,
the General Partner shall cause written notice thereof to be delivered to each
Limited Partner in accordance with the provisions of Section 15.1 at least 10
days prior to the date in which (1) the books of the Company shall close, or a
record date





                                       34
<PAGE>   40
be taken, for such dividend, distribution or right or (ii) such reorganization,
reclassification, recapitalization, consolidation, merger, transfer,
liquidation, dissolution or winding up shall be effective, as the case may be.
Failure to mail such notice or any defect therein shall not affect the validity
of the transaction, provided that the foregoing shall not otherwise limit or
affect the General Partner's liability to any Limited Partner hereunder in the
event that the General Partner willfully breaches any of its material
obligations hereunder.

                                  ARTICLE IX.

       SECTION 9.1   RECORDS AND ACCOUNTING.

       The General Partner shall keep or cause to be kept at the principal
office of the Partnership appropriate books and records with respect to the
Partnership's business.  Any records maintained by or on behalf of the
Partnership in the regular course of its business may be kept on, or be in the
form of, punch cards, magnetic tape or other media, photographs, micro graphics
or any other information storage device, provided that the records so
maintained are convertible into clearly legible written form within a
reasonable period of time. The books of the Partnership shall be maintained on
an accrual basis in accordance with generally accepted accounting principles
for financial reporting purposes and in accordance with tax accounting
principles for tax reporting purposes.  The Limited Partners shall have the
right to inspect Partnership books and records during normal business hours and
upon prior written notice.

       The fiscal year of the Partnership shall be the calendar year.

       SECTION 9.3   REPORTS.

       As soon as practicable after the conclusion of each Partnership Year,

prepared on a consolidated basis with the Partnership, for such Partnership
Year.

                                  TAX MATTERS

       SECTION 10.1  PREPARATION OF TAX RETURNS.

       The General Partner shall arrange for the preparation and timely filing
of all returns of Partnership income, gains, deductions, losses and other items
required of the Partnership for federal and state income tax purposes and shall
use all reasonable efforts to furnish, within ninety (90) days of the close of
each taxable year, the tax information reasonably required or reasonable
requested by Limited Partners for federal and state income tax reporting
purposes.

       SECTION 10.2  TAX ELECTIONS.

       The General Partner shall have the right to determine whether to make
any available election pursuant to the Code (including, without limitation, the
election available under Section 754 of the Code) on behalf of the Partnership.
Subject to the provisions of Section 7.7.B, any such election hereunder shall
be made by the General Partner upon its determination in its reasonable
discretion that such election is in the best interests of the Partners.  The
General Partner shall have the right to seek to revoke any such election upon
the General Partner's determination in its reasonable discretion that such
revocation is in the best interests of the Partners.

       SECTION 10.3  TAX MATTERS PARTNER.

       A.     GENERAL.  The General Partner shall be the "tax matters partner"
of the Partnership for federal income tax purposes. Pursuant to Section
6223(c)(3) of the Code, upon receipt of notice from the IRS of the beginning of
an administrative proceeding with respect to the Partnership, the tax matters
partner shall furnish the IRS with the name, address, taxpayer identification
number and profit interest of each of the Limited Partners and any Assignees;
provided, however, that such information is provided to the Partnership by the
Limited Partners.

       B.     POWERS.  The tax matters partner is authorized, but not required:

              (1)    to enter into any settlement with the IRS with respect to
any administrative or judicial proceedings for the adjustment of Partnership
items required to be taken into account by a Partner for income tax purposes
(such administrative proceedings being referred to as a "tax audit" and such
judicial proceedings being referred to as "judicial review"), and in the
settlement agreement the tax matters partner may expressly state that such
agreement shall bind all Partners, except that such settlement agreement shall
not bind any Partner (i) who (within the time prescribed pursuant to the Code
and Regulations) files a statement with the IRS providing that the tax matters
partner shall not have the authority to enter into a settlement agreement on
behalf of such Partner or (ii) who is a "notice partner" (as defined in Section
6231(a)(8) of the Code) or a member of a "notice group" (as defined in Section
6223(b)(2) of the Code);





                                       36
<PAGE>   42
              (2)    in the event that a notice of a final administrative
adjustment at the Partnership level of any item required to be taken into
account by a Partner for tax purposes  (a "final adjustment") is mailed to the
tax matters partner, to seek judicial review of such final adjustment,
including the filing of a petition for readjustment with the Tax Court or the
filing of a complaint for refund with the United States Claims Court or the
District Court of the United States for the district in which the Partnership's
principal place of business is located;

              (3)    to intervene in any action brought by any other Partner
for judicial review of a final adjustment;

              (4)    to file a request for an administrative adjustment with
the IRS at any time and, if any part of such request is not allowed by the IRS,
to file an appropriate pleading (petition or complaint) for judicial review
with respect to such request;

              (5)    to enter into an agreement with the IRS to extend the
period for assessing any tax which is attributable to any item required to be
taken into account by a Partner for tax purposes, or an item affected by such
item; and

              (6)    to take any other action on behalf of the Partners of the
Partnership in connection with any tax audit or judicial review proceeding to
the extent permitted by applicable law or regulations.

       The taking of any action and the incurring of any expense by the tax
matters partner in connection with any such proceeding, except to the extent
required by law, is a matter in the sole and absolute discretion of the tax
matters partner and the provisions relating to indemnification of the General
Partner set forth in Section 7.6 hereof shall be fully applicable to the tax
matters partner in its capacity as such.

       C.     REIMBURSEMENT.

       The tax matters partner shall receive no compensation for its services.
All costs and expenses incurred by the tax matters partner in performing its
duties as such (including legal and accounting fees and expenses and expenses
reimbursable under Section 7.4 hereof) shall be borne by the Partnership.
Nothing herein shall be construed to restrict the Partnership from engaging an
accounting firm or a law firm to assist the tax matters partner in discharging
its duties hereunder.

       SECTION 10.4  ORGANIZATIONAL EXPENSES.

       The Partnership shall elect to deduct expenses, if any, incurred by it
in organizing the Partnership ratably over a sixty (60) month period as
provided in Section 709 of the Code.





                                       37
<PAGE>   43
       SECTION 10.5  WITHHOLDING.

       Each Limited Partner hereby authorizes the Partnership to withhold from
or pay on behalf of or with respect to such Limited Partner any amount of
federal, state, local, or foreign taxes that the General Partner reasonably
determines that the Partnership is required to withhold or pay with respect to
any amount distributable or allocable to such Limited Partner pursuant to this
Agreement, including, without limitation, any taxes required to be withheld or
paid by the Partnership pursuant to Section 1441, 1442, 1445, or 1446 of the
Code. Any amount paid on behalf of or with respect to a Limited Partner shall
constitute a recourse loan by the Partnership to such Limited Partner, which
loan shall be repaid by such Limited Partner within fifteen (15) days after
notice from the General Partner that such payment must be made unless (i) the
Partnership withholds such payment from a distribution which would otherwise be
made to the Limited Partner or (ii) the General Partner determines, in its sole
and absolute discretion, that such payment may be satisfied out of the
available funds of the Partnership which would, but for such payment, be
distributed to the Limited Partner. Any amounts withheld pursuant to the
foregoing clauses (i) or (ii) shall be treated as having been distributed to
such Limited Partner. Each Limited Partner hereby unconditionally and
irrevocably grants to the Partnership a security interest in such Limited
Partner's Partnership Interest to secure such Limited Partner's obligation to
pay to the Partnership any amounts required to be paid pursuant to this Section
10.5. In the event that a Limited Partner fails to pay any amounts owed to the
Partnership pursuant to this Section 10.5 when due, the General Partner may, in
its sole and absolute discretion, elect to make the payment to the Partnership
on behalf of such defaulting Limited Partner, and in such event shall be deemed
to have loaned such amount to such defaulting Limited Partner and shall succeed
to all rights and remedies of the Partnership as against such defaulting
Limited Partner. In such event the General Partner shall have the right to
receive distributions that would otherwise be distributable to such defaulting
Limited Partner until such time as such loan, together with all interest
thereon, has been paid in full, and any such distributions so received by the
General Partner shall be treated as having been distributed to the defaulting
Limited Partner and immediately paid by the defaulting Limited Partner to the
General Partner in repayment of such loan. Any amounts payable by a Limited
Partner hereunder shall bear interest at the lesser of (A) the base rate on
corporate loans at large United States money center commercial banks, as
published from time to time in the Wall Street Journal, plus four (4)
percentage points or (B) the maximum lawful rate of interest on such
obligation, such interest to accrue from the date such amount is due (i.e.,
fifteen (15) days after demand) until such amount is paid in full. Each Limited
Partner shall take such actions as the Partnership or the General Partner shall
request in order to perfect or enforce the security interest created hereunder.

                                  ARTICLE XI.

                           TRANSFERS AND WITHDRAWALS

       SECTION 11.1  TRANSFER.

       A.     DEFINITION.   The term "transfer," when used in this Article XI
with respect to a Partnership Interest or a Partnership Unit, shall be deemed
to refer to a transaction by which a Partner purports to assign all or any part
of its interest in the Partnership to another Person, and includes a sale,
assignment, gift, pledge, encumbrance, hypothecation, mortgage, exchange or any
other disposition by law or otherwise. However, the term "transfer" when used
in this Article XI does not include any purchase of Partnership Units by the
General Partner from a Limited Partner  pursuant to the exercise of the Put
Right in accordance with the provisions of Section 8.6 hereof.

       B.     GENERAL.  No Partnership Interest held by a Limited Partner may
be transferred, in whole or in part, except in accordance with the terms and
conditions set forth in this Article XI. Any transfer or purported transfer of
a Limited Partner Interest not made in accordance with this Article XI shall be
null and void.

       C.     TRANSFER BY GENERAL PARTNER.  The General Partner may not
transfer its General Partner Interest in the Partnership without the Consent of
all Limited Partners unless (1) the transfer of the General Partner Interest is
to an Affiliate of the General Partner, or (2) the transfer of the General
Partner Interest is pursuant to or in connection with a merger (including a
triangular merger), consolidation or other combination with or into another
Person, reclassification, recapitalization or change of outstanding Shares (a
"Business Combination"), and an Equity Adjustment is made to the Consideration
to be received by the Limited Partners, or (3) the transfer of the General
Partner Interest is pursuant to any transaction further described in Section
8.6.A(4) or 8.7 and the General Partner shall have provided requisite notice to
the Limited Partners.

       SECTION 11.2  LIMITED PARTNERS' RIGHTS TO TRANSFER.

       A.     GENERAL. Except to the extent expressly permitted in Section
11.2.B or in connection with the exercise of a Put Right pursuant to Section
8.6, a Limited Partner may not transfer all or any portion of its Limited
Partner Interest, or any of such Limited Partner's economic rights as a Limited
Partner other than to a Permitted Transferee (subject to Sections 11.2.D and
11.2.E), without the prior written consent of the General Partner, which
consent may be withheld by the General Partner, in its sole and absolute
discretion, for any reason or for no reason. Any transfer otherwise permitted
under Section 11.2.B shall be subject to the conditions set forth in Sections
11.2.D and 11.2.E, and all permitted transfers shall be subject to Section 11.3
and Section 11.4.

       B.     INCAPACITATED LIMITED PARTNERS. If a Limited Partner is
Incapacitated, the executor, administrator, trustee, committee, guardian,
conservator or receiver of such Limited Partner's estate shall have all the
rights of a Limited Partner, but not more rights than those enjoyed by 
other Limited





                                       39
<PAGE>   45
Partners for the purpose of settling or managing the estate and such power as
the Incapacitated Limited Partner possessed to transfer all or any part of its
interest in the Partnership. The Incapacity of a Limited Partner, in and of
itself, shall not dissolve or terminate the Partnership.

       C.     PERMITTED TRANSFERS.  Subject to the provisions of Sections
11.2.D and 11.2.E a Limited Partner may, at any time, transfer its economic
rights as a Limited Partner to a Permitted Transferee.  Any such Permitted
Transferee shall, following the closing of any such transfer of Partnership
Units, and upon provision of written notice thereof to the General Partner,
have the rights of an Assignee.  Subject to the Provisions of Section 11.3 any
such Assignee shall only become a Substituted Limited Partner upon the prior
written consent of the General Partner.

       D.     NO TRANSFERS VIOLATING SECURITIES LAWS. The General Partner may
in its sole discretion, prohibit any transfer of Partnership Units by a Limited
Partner if, in the opinion of legal counsel to the Partnership, such transfer
would require filing of a registration statement under the Securities Act or
would otherwise violate any federal, or state securities laws or regulations
applicable to the Partnership or the Partnership Unit.

       E.     GENERAL PARTNER AUTHORITY WITH REGARD TO OTHER TRANSFERS.  The
General Partner may, in its sole discretion, prohibit any transfer of
Partnership Units by a Limited Partner, if (i) in the opinion of legal counsel
it would result in the termination of the Partnership of the Partnership for
federal income tax purposes, (ii) in the opinion of legal counsel for the
Partnership, it would adversely affect the ability of the General Partner to
continue to qualify as a REIT or would subject the General Partner to any
additional taxes under Section 857 or Section 4981 of the Code or (iii) such
transfer is effectuated through an "established securities market" or a
"secondary market (or the substantial equivalent thereof)" within the meaning
of Section 7704 of the Code.

       SECTION 11.3  SUBSTITUTED LIMITED PARTNERS.

       A.     CONSENT OF GENERAL PARTNER.  No Limited Partner shall have the
right to substitute a transferee as a Limited Partner in its place (whether or
not the transfer of the Limited Partner's Partnership Interest is permitted
under Section 11.2). The General Partner shall, however, have the right to
consent to the admission of a transferee of the interest of a Limited Partner
pursuant to this Section 11.3 as a Substituted Limited Partner, which consent
may be given or withheld by the General Partner in its sole and absolute
discretion and for any reason or no reason. The General Partner's failure or
refusal to permit a transferee of any such interests to become a Substituted
Limited Partner shall not give rise to any cause of action against the
Partnership or any Partner.

       B.     RIGHTS OF SUBSTITUTED LIMITED PARTNER. A transferee who has been
admitted as a Substituted Limited Partner in accordance with this Article XI
shall have all the rights and powers and be subject to all the restrictions and
liabilities of a Limited Partner under this Agreement. The admission of any
transferee as a Substituted Limited Partner shall be conditioned upon the
transferee executing and delivering to the Partnership an acceptance of all the
terms and conditions of this Agreement (including, without limitation, the
provisions of Section 2.4) and such other documents or instruments as may be
required to effect the admission.

<PAGE>   46
       C.      AMENDMENT AND RESTATEMENT OF EXHIBIT A. Upon the admission of a
Substituted Limited Partner, the General Partner shall amend and restate
Exhibit A hereto to reflect the name, address, Capital Account, number of
Partnership Units of such Substituted Limited Partner and to eliminate or
adjust, if necessary, the name, address, Capital Account and Percentage
Interest of the predecessor of such Substituted Limited Partner (and any other
Partner, as necessary).

       SECTION 11.4  ASSIGNEES.

       If the General Partner, in its sole and absolute discretion, does not
consent to the admission of any transferee under Section 11.3 as a Substituted
Limited Partner, such transferee shall be considered an Assignee for purposes
of this Agreement. An Assignee shall be entitled to all the rights of an
assignee of a limited partner interest under the Act, including the right to
receive distributions from the Partnership and the share of Net Income, Net
Losses, gain, loss and Recapture Income attributable to the Partnership Units
assigned to such transferee, and, as applicable shall have the rights granted
to the Limited Partners under Section 8.6, but shall not be deemed to be a
holder of Partnership Units for any other purpose under this Agreement, and
shall not be entitled to vote such Partnership Units in any matter presented to
the Limited Partners for a vote (such Partnership Units being deemed to have
been voted in the same manner as the Partnership Units held by the General
Partner). In the event any such transferee desires to make a further assignment
of any such Partnership Units, such transferee shall be subject to all the
provisions of this Article XI to the same extent and in the same manner as any
Limited Partner desiring to make an assignment of Partnership Units. The
General Partner shall have no liability under any circumstances with respect to
any Assignee as to which it does not have actual notice.

       SECTION 11.5  GENERAL PROVISIONS.

        A.    WITHDRAWAL OF LIMITED PARTNER.  No Limited Partner may withdraw
from the Partnership other than as a result of a permitted transfer of all of
such Limited Partner's Partnership Units in accordance with this Article XI or,
as applicable,  pursuant to the transfer of all of its Partnership Units under
Section 8.6 hereof.

       B.     TERMINATION OF STATUS AS LIMITED PARTNER.  Any Limited Partner
who shall transfer all of its Partnership Units in a transfer permitted
pursuant to this Article XI or pursuant to the exercise of the Put Right under
Section 8.6 hereof shall immediately cease to be a Limited Partner.

       C.     ALLOCATIONS. If any Partnership Interest is transferred in
compliance with the provisions of this Article XI or, as applicable,
transferred pursuant to Section 8.6 or hereof, Net Income, Net Losses, each
item thereof and all other items attributable to such interest shall be divided
and allocated between the transferor Partner and the transferee Partner by
taking into account their varying interests during the fiscal year in
accordance with Section 706 of the Code, using any permissible method of
allocation under such Code Section.

       SECTION 12.1  ADMISSION OF SUCCESSOR GENERAL PARTNER.

       A successor to all of the General Partner's General Partner Interest
pursuant to Section 11.1.C hereof who is proposed to be admitted as a successor
General Partner shall be admitted  to the Partnership as the General Partner.
Any such transferee shall carry on the business of the Partnership without
dissolution. In each case, the admission shall be subject to the successor
General Partner's executing and delivering to the Partnership an acceptance of
all of the terms and conditions of this Agreement and such other documents or
instruments as may be reasonably required by the Limited Partners to effect the
admission.

       SECTION 12.2  AMENDMENT OF AGREEMENT AND CERTIFICATE OF LIMITED
PARTNERSHIP.

       For the admission to the Partnership of any Partner in accordance with
the provisions hereof, the General Partner shall take all steps necessary and
appropriate under the Act to amend the records of the Partnership (including an
amendment and restatement of Exhibit A hereto and any requisite amendments to
this Agreement to reflect the Residual Percentage properly allocable to such
Partner)) and, if necessary, to prepare as soon as practicable an amendment of
this Agreement and, if required by law, shall prepare and file an amendment to
the Certificate and may for such purpose exercise the power of attorney granted
pursuant to Section 2.4 hereof.

                                 ARTICLE XIII.

                          DISSOLUTION AND LIQUIDATION

       SECTION 13.1  DISSOLUTION.

       The Partnership shall not be dissolved by the admission of a Substituted
Limited Partner or by the admission of a successor General Partner in
accordance with the terms of this Agreement. Upon the withdrawal of the General
Partner, any successor General Partner shall continue the business of the
Partnership. The Partnership shall dissolve, and its affairs shall be wound up,
upon the first to occur of any of the following ("Liquidating Events") :

              (1)    the expiration of its term as provided in Section 2.5
hereof;

              (2)    an event of withdrawal of the General Partner, as defined
in the Act (other than an event of bankruptcy), unless, within ninety (90) days
after the withdrawal a "majority in interest" (as defined below) of the
remaining Partners Consent in writing to continue the business of the
Partnership and to the appointment, effective as of the date of withdrawal, of
a substitute General Partner;





                                       42
<PAGE>   48
              (3)    the sale of all or substantially all of the assets of the
Partnership;

              (4)    on or after October 3, 2003, the election of the General
Partner, in its sole discretion, to dissolve the Partnership;

              (5)    the entry of a decree of judicial dissolution of the
Partnership pursuant to the provisions of the Act;

              (6)    the sale of the Property;

              (7)    a final and non-appealable judgment is entered by a court
of competent jurisdiction ruling that the General Partner is bankrupt or
insolvent, or a final and non-appealable order for relief is entered by a court
with appropriate jurisdiction against the General Partner, in each case under
any federal or state bankruptcy or insolvency laws as now or hereafter in
effect, unless prior to or within ninety days after of the entry of such order
or judgment a "majority in interest" (as defined below) of the Partners Consent
in writing to continue the business of the Partnership and to the appointment,
effective as of a date prior to the date of such order or judgment, of a
substitute General Partner.

As used herein, a "majority in interest" shall refer to Partners (other than
the General Partner) who hold more than fifty percent (50%) of the outstanding
Partnership Units held by such Partners.

       SECTION 13.2  WINDING UP.

        A.    GENERAL. Upon the occurrence of a Liquidating Event, and as
applicable, the failure of the Partners to continue the business of the
Partnership, the Partnership shall continue solely for the purposes of winding
up its affairs in an orderly manner, liquidating its assets, and satisfying the
claims of its creditors and Partners. No Partner shall take any action that is
inconsistent with, or not necessary to or appropriate for, the winding up of
the Partnership's business and affairs. The General Partner (or, in the event
there is no remaining General Partner, any Person elected by a majority in
interest of the Limited Partners (the "Liquidator")) shall be responsible for
overseeing the winding up and dissolution of the Partnership and shall take
full account of the Partnership's liabilities and property and the Partnership
property shall be liquidated as promptly as is consistent with obtaining the
fair value thereof, and the proceeds therefrom shall be applied and distributed
in the following order:

              (1)    first, to the payment and discharge of all of the
Partnership's debts and liabilities to creditors other than the Partners;

              (2)    second, to the payment and discharge of all of the
Partnership's debts and liabilities to the Partners;





                                       43
<PAGE>   49
              (3)    third, to the Limited Partners in an amount equal to any
LP Return Accrual owing such Limited Partners, pro rata in accordance with the
amount of such LP Return Accrual owing each such Limited Partner;

              (4)    fourth, to the Limited Partners in an amount equal to the
Unpaid LP Return owing such Limited Partners, pro rata in accordance with the
amount of such Unpaid LP Return owing each such Limited Partner;

              (5)    fifth, to the General Partner in an amount equal to  any
Unpaid GP Return owing the General Partner;

              (6)    sixth, to the General Partner in an amount equal to the
Unreturned Capital owing the General Partner;

              (7)    seventh, to the Limited Partners in an amount equal to the
Unreturned Capital owing the Limited Partners pro rata in accordance with the
Unreturned Capital owing each such Limited Partner; and

              (8)    finally, the balance, if any, shall be distributed to the
Partners pro rata, in accordance with their respective Residual Percentages.

       Provided, however, that under no circumstances shall a Limited Partner
receive any distributions under this Section 13.2.A with respect to any
Partnership Units with regard to which the Limited Partner has exercised the
Put Right.

       B.     DEFERRED LIQUIDATION. Notwithstanding the provisions of Section
13.2.A above which require liquidation of the assets of the Partnership, but
subject to the order of priorities set forth therein, if prior to or upon
dissolution of the Partnership the Liquidator determines that an immediate sale
of part or all of the Partnership's assets would be impractical or would cause
undue loss to the Partners, the Liquidator may, in its sole and absolute
discretion, defer for a reasonable time the liquidation of any assets except
those necessary to satisfy liabilities of the Partnership (including to those
Partners as creditors) or distribute to the Partners, in lieu of cash, as
tenants in common and in accordance with the provisions of Section 13.2.A
above, undivided interests in such Partnership assets as the Liquidator deems
not suitable for liquidation. Any such distributions in kind shall be made only
if, in the good faith judgment of the Liquidator, such distributions in kind
are in the best interest of the Partners, and shall be subject to such
conditions relating to the disposition and management of such properties as the
Liquidator deems reasonable and equitable and to any agreements governing the
operation of such properties at such time. The Liquidator shall determine the
fair market value of any property distributed in kind using such  reasonable
method of valuation as it may adopt.

       C.     LIQUIDATING TRUST. In the discretion of the General Partner, a
pro rata portion of the distributions that would otherwise be made to the
General Partner and Limited Partners pursuant to this Article XIII may be: (A)
distributed to a trust established for the benefit of  the General Partner





                                       44
<PAGE>   50
and Limited Partners for the purposes of liquidating Partnership assets,
collecting amounts owed to the Partnership and paying any contingent or
unforeseen liabilities or obligations of the Partnership or of the General
Partner arising out of or in connection with the Partnership (in which case the
assets of any such trust shall be distributed to the General Partner and
Limited Partners from time to time, in the reasonable discretion of the General
Partner, in the same proportions as the amount distributed to such trust by the
Partnership would otherwise have been distributed to the General Partner and
Limited Partners pursuant to this Agreement); or (B) withheld to provide a
reasonable reserve for Partnership liabilities (contingent or otherwise) and to
reflect the unrealized portion of any installment obligations owed to the
Partnership, provided that such withheld amounts shall be distributed to the
General Partner and Limited Partners in the manner and order of priority set
forth in Section 13.2.A as soon as practicable.

       SECTION 13.3  DEFICIT CAPITAL ACCOUNTS.

       If any Partner has a deficit balance in its Capital Account (after
giving effect to all contributions, distributions and allocations for all
taxable years, including the year during which such liquidation occurs), such
Partner shall have no obligation to make any contribution to the capital of the
Partnership with respect to such deficit, and such deficit shall not be
considered a debt owed to the Partnership or to any other Person for any
purpose whatsoever.

       SECTION 13.4  DEEMED DISTRIBUTION AND RECONTRIBUTION.

       Notwithstanding any other provision of this Article XIII, in the event
the Partnership is deemed liquidated within the meaning of Regulations Section
1.704-1(b)(2)(ii)(g) but no Liquidating Event has occurred, the Partnership's
property shall not be liquidated, the Partnership's liabilities shall not be
paid or discharged and the Partnership's affairs shall not be wound up.
Instead, for federal income tax purposes and for purposes of maintaining
Capital Accounts pursuant to Exhibit B hereto, the Partnership shall be deemed
to have distributed its assets in kind to the General Partner and Limited
Partners, who shall be deemed to have assumed and taken such assets subject to
all Partnership liabilities, all in accordance with their respective Capital
Accounts. Immediately thereafter, the General Partner and Limited Partners
shall be deemed to have recontributed the Partnership assets in kind to the
Partnership, which shall be deemed to have assumed and taken such assets
subject to all such liabilities.

       SECTION 13.5  RIGHTS OF LIMITED PARTNERS.

       Except as otherwise provided in this Agreement, each Limited Partner
shall look solely to the assets of the Partnership for the return of its
Capital Contributions and shall have no right or power to demand or receive
property other than cash from the Partnership. Except as otherwise provided in
this Agreement, no Limited Partner shall have priority over any other Partner
as to the return of its Capital Contributions, distributions, or allocations.

<PAGE>   51
       SECTION 13.6  NOTICE OF DISSOLUTION.

       In the event a Liquidating Event occurs or an event occurs that would,
but for provisions of an election or objection by one or more Partners pursuant
to Section 13.1 above, result in a dissolution of the Partnership, the General
Partner shall, within thirty (30) days thereafter, provide written notice
thereof to each of the Partners.

       SECTION 13.7  TERMINATION OF PARTNERSHIP AND CANCELLATION OF CERTIFICATE
OF LIMITED PARTNERSHIP.

       Upon the completion of the liquidation of the Partnership cash and
property as provided in Section 13.2 above, all Partnership Units shall be
canceled, including the Put Right associated therewith, the Partnership shall
be terminated, the Certificate and all qualifications of the  Partnership as a
foreign limited partnership in jurisdictions other than the State of Delaware
shall be canceled, and such other actions as may be necessary to terminate the
Partnership shall be taken.

       SECTION 13.8  REASONABLE TIME FOR WINDING UP.

       A reasonable time shall be allowed for the orderly winding up of the
business and affairs of the Partnership and the liquidation of its assets
pursuant to Section 13.2 above, in order to minimize any losses otherwise
attendant upon such winding-up, and the provisions of this Agreement shall
remain in effect among the Partners during the period of liquidation.

       SECTION 13.9  WAIVER OF PARTITION.

       Each Partner hereby waives any right to partition of the Partnership
property.

       SECTION 13.10 LIABILITY OF LIQUIDATOR.

       The Liquidator shall be indemnified and held harmless by the Partnership
from and against any and all claims, liabilities, costs, damages, and causes of
action of any nature whatsoever arising out of or incidental to the
Liquidator's taking of any action authorized under or within the scope of this
Agreement; provided, however, that the Liquidator shall not be entitled to
indemnification, and shall not be held harmless, where the claim, demand,
liability, cost, damage or cause of action at issue arises out of (i) a matter
entirely unrelated to the Liquidator's action or conduct pursuant to the
provisions of this Agreement or (ii) the proven willful misconduct or gross
negligence of the Liquidator.

                  AMENDMENT OF PARTNERSHIP AGREEMENT; MEETINGS

       SECTION 14.1  AMENDMENTS.

       A.     GENERAL. Amendments to this Agreement may be proposed by the
General Partner or by any Limited Partners holding twenty-five percent (25%) or
more of the Partnership Interests held by Limited Partners. Following such
proposal (except an amendment pursuant to Section 14.1.B below), the General
Partner shall submit any proposed amendment to the Limited Partners. The
General Partner shall seek the written vote of the Partners on the proposed
amendment or shall call a meeting to vote thereon and to transact any other
business that it may deem appropriate. For purposes of obtaining a written
vote, the General Partner may require a response within a reasonable specified
time, but not less than ten (10) days, and failure to respond in such time
period shall constitute a vote against the General Partner's recommendation
with respect to the proposal. Except as provided in Section 14.1.B, 14.1.C or
14.1.D below, a proposed amendment shall be adopted and be effective as an
amendment hereto if it is approved by the General Partner and it receives the
Consent of Partners holding a majority of the Partnership Units then held by
Limited Partners.

       B.     AMENDMENTS NOT REQUIRING LIMITED PARTNER APPROVAL.
Notwithstanding Section 14.1.A or Section 14.1.C hereof, the General Partner
shall have the power, without the Consent of any Limited Partner, to amend this
Agreement as may be required to facilitate or implement any of the following
purposes:

              (1)    to add to the obligations of the General Partner or
surrender any right or power granted to the General Partner or any Affiliate of
the General Partner for the benefit of the Limited Partners;

              (2)    to reflect the admission, substitution, termination, or
withdrawal of any Partner in accordance with this Agreement;

              (3)    to reflect a change that does not adversely affect any of
the Limited Partners in any material respect, or to cure any ambiguity, correct
or supplement any provision in this Agreement not inconsistent with law or with
other provisions, or make other changes with respect to matters arising under
this Agreement that will not be inconsistent with law or with the provisions of
this Agreement or as may be expressly provided by any other provisions of this
Agreement; and

              (4)    to satisfy any requirements, conditions, or guidelines
contained in any order, directive, opinion, ruling or regulation of a federal,
state or local agency or contained in federal, state or local law.

The General Partner shall notify the Limited Partners when any action under
this Section 14.1.B is taken.

<PAGE>   53
       C.     OTHER AMENDMENTS REQUIRING CERTAIN LIMITED PARTNER APPROVAL.
Notwithstanding anything in this Section 14.1 to the contrary, this Agreement
shall not be amended without the Consent of such Partner adversely affected if
such amendment would (i) convert a Limited Partner's interest in the
Partnership into a general partner's interest, (ii) modify the limited
liability of a Limited Partner, (iii) alter rights of Partners to receive
distributions pursuant to Article V or XIII or the allocations specified in
Article VI, (iv) amend Section 8.6 or any defined terms set forth in Article I
that relate to the Put Right, (v) amend the provisions of Section 7.3 or 8.7,
or (vi) amend this Section 14.1.C.

       D.     AMENDMENT AND RESTATEMENT OF EXHIBIT A NOT AN AMENDMENT.
Notwithstanding anything in this Article XIV or elsewhere in this Agreement to
the contrary, any amendment and restatement of Exhibit A hereto by the General
Partner to reflect events or changes otherwise authorized or permitted by this
Agreement, whether pursuant to Section 7.1.A(20) hereof or otherwise, shall not
be deemed an amendment of this Agreement and may be done at any time and from
time to time, as necessary by the General Partner without the Consent of any
Limited Partner.

       SECTION 14.2  MEETINGS OF THE PARTNERS.

       A.     GENERAL. Meetings of the Partners may be called by the General
Partner and shall be called upon the receipt by the General Partner of a
written request by Limited Partners holding twenty-five percent (25%) or more
of the Partnership Interests held by the Limited Partners. The call shall state
the nature of the business to be transacted. Notice of any such meeting shall
be given to all Partners not less than five (5) days nor more than thirty (30)
business days prior to the date of such meeting. Partners may vote in person or
by proxy at such meeting. Whenever the vote or Consent of Limited Partners is
required under this Agreement, such vote or Consent may be given at a meeting
of Partners or may be given in accordance with the procedure prescribed in
Section 14.1.A above. Except as otherwise expressly provided in this Agreement,
the Consent of holders of a majority of the Partnership Units held by Limited
Partners shall constitute the "Consent" of the Limited Partners hereunder.

       B.     ACTIONS WITHOUT A MEETING. Any action required or permitted to be
taken at a meeting of the Partners may be taken without a meeting if a written
consent setting forth the action so taken is signed by Partners (including the
General Partner) who hold a majority of the Partnership Units held by the
Partners hereunder (or such other percentage as required by this Agreement).
Such consent may be in one instrument or in several instruments, and shall have
the same force and effect as a vote of a majority of the Partnership Units of
the Partners (or, as applicable, such other percentage as required by this
Agreement). Such consent shall be filed with the General Partner. An action so
taken shall be deemed to have been taken at a meeting held on the effective
date so certified.  This Section 14.2.B shall not be construed as limiting the
approval rights granted to the Limited Partners under Section 7.3 hereof.

       C.     PROXY. Each Limited Partner may authorize any Person or Persons
to act for him by proxy on all matters in which a Limited Partner is entitled
to participate, including waiving notice of any meeting, or voting or
participating at a meeting. Every proxy must be signed by the Limited





                                       48
<PAGE>   54
Partner or its attorney-in-fact. No proxy shall be valid after the expiration
of eleven (11) months from the date thereof unless otherwise provided in the
proxy. Every proxy shall be revocable at the pleasure of the Limited Partner
executing it, such revocation to be effective upon the Partnership's receipt of
written notice thereof.

       D.     CONDUCT OF MEETING. Each meeting of Partners shall be conducted
by the General Partner or such other Person as the General Partner may appoint
pursuant to such  rules for the conduct of the meeting as the General Partner
or such other Person deems appropriate in its sole discretion.

                                  ARTICLE XV.

Partner or Assignee at the address set forth in Exhibit A hereto or such other
address as the Partners shall notify the General Partner in writing. Such

       No failure by any party to insist upon the strict performance of any
covenant, duty, agreement or condition of this Agreement or to exercise any

                               WARRANT AGREEMENT

         This Warrant  Agreement, is made and entered into as of October 3,
1997, by and between American Industrial Properties REIT, a Texas real estate
investment trust (the "Company"), and Shidler West Acquisition Company, LLC,
("Investor").

         WHEREAS, the Company, AIP-SWAG Operating Partnership, L.P., a Delaware
limited partnership (the "Operating Partnership"), and Shidler West Investment
Corporation ("Shidler West"), acting on behalf of Investor and AG Industrial
Investors, L.P., have entered into a Contribution and Exchange Agreement, dated
as of September 25, 1997 (the "Contribution Agreement"), pursuant to which,
among other things, the Operating Partnership agreed to acquire the right to
purchase certain real property from Shidler West; and

         WHEREAS, pursuant to the Contribution Agreement, the Company has
agreed to issue to Investor a warrant as hereinafter described (the "Warrant")
to purchase up to an aggregate of 100,000 (subject to adjustment as hereinafter
provided)  shares of beneficial interest, par value $0.10 per share (the
"Common Shares"), of the Company.

         NOW, THEREFORE, the parties hereto, in consideration of the foregoing,
the mutual covenants and agreements hereinafter set forth, and other good and
valuable consideration, the receipt and sufficiency of which hereby are
acknowledged, hereby agree as follows:

1.                        Form of Warrant.  The text of the Warrant certificate
                 and of the form of election to purchase Common Shares (as used
                 herein the term "Shares" refers to the Common Shares and,
                 where appropriate, such term shall also mean the other
                 securities or property purchasable upon the exercise of a
                 Warrant as provided for herein upon the happening of certain
                 events) shall be substantially as set forth in Exhibit A
                 attached hereto (the "Warrant Certificate"), which is hereby
                 incorporated by reference and made a part hereof.  The Warrant
                 Certificate shall be executed on behalf of the Company by an
                 appropriate officer of the Company.  Such signature may be in
                 the form of a facsimile thereof and may be impressed, affixed,
                 imprinted or otherwise reproduced on the Warrant Certificate.
                 The Warrant Certificate shall be dated the date of execution
                 by an appropriate officer of the Company either upon initial
                 issuance or upon any division, exchange, substitution or
                 transfer thereof that is permitted by this Agreement.

2.                        Registration.  The Warrant Certificate and any
                 certificates issued upon transfer or exchange of the Warrant
                 shall be numbered and shall be registered in a Warrant
                 register.  The Company shall be entitled to treat the
                 registered holder of any Warrant in the Warrant register (the
                 "Holder") as the owner in fact thereof for all purposes
                 (notwithstanding any notation of ownership or other writing
                 thereon made by anyone) and shall not be bound to recognize
                 any equitable or other claim to or interest in such Warrant on
                 the part of any other person, and shall not be liable for any
                 registration or transfer of a Warrant that is registered or to
                 be registered in the name of a fiduciary or the nominee of a
                 fiduciary unless made with the actual knowledge that a
                 fiduciary or nominee is committing a breach of trust in
<PAGE>   2
                 requesting such registration of transfer, or with knowledge of
                 such facts that its participation therein amounts to bad
                 faith.  The Warrant shall be registered initially in the name
                 of "Shidler West Acquisition Company, LLC."

3.                        Transfer of Warrant. The Warrant shall be
                 transferable only on the books of the Company upon delivery of
                 the Warrant Certificate, duly endorsed by the Holder or by its
                 duly authorized attorney or representative, or accompanied by
                 proper evidence of succession, assignment or authority to
                 transfer.  In all cases of transfer by an attorney, the
                 original power of attorney, duly approved, or an official copy
                 thereof, duly certified, shall be deposited with the Company.
                 In case of transfer by executors, administrators, guardians or
                 other legal representatives, duly authenticated evidence of
                 their authority shall be produced, and may be required to be
                 deposited with the Company in its discretion.  Upon any
                 registration of transfer, the Company shall deliver a new
                 Warrant Certificate or Warrant Certificates to the person or
                 persons entitled thereto.  The Warrant Certificate may be
                 exchanged, at the option of the Holder thereof, for another
                 Warrant Certificate, or other Warrant Certificates of
                 different denominations, of like tenor and representing in the
                 aggregate the right to purchase a like number of Shares upon
                 surrender of the Warrant Certificate to the Company or its
                 duly authorized agent.  Notwithstanding the foregoing, the
                 Company shall have no obligation to cause a Warrant to be
                 transferred on its books to any person unless the Holder of
                 such Warrant shall furnish to the Company evidence of
                 compliance with the Securities Act of 1933, as amended (the "
                 Securities Act "), in accordance with the terms of the legend
                 set forth in Section 13 of this Agreement.  The Company shall
                 cancel and dispose of Warrant Certificates surrendered for
                 exchange or for registration of transfer in a manner
                 satisfactory to the Company.

4.                        Term of Warrant; Exercise of Warrant.  The Warrant
                 entitles the registered owner thereof to purchase up to
                 100,000 Common Shares at a purchase price of $3.50 per share
                 (the "Exercise Price") at any time after the date hereof and
                 on and before 5:00 p.m. Central Time on October 3, 2000 (the
                 "Expiration Date").  The Exercise Price and the Shares
                 issuable upon exercise of the Warrant are subject to
                 adjustment upon the occurrence of certain events specified in
                 Section 8 of this Agreement.  Subject to the provisions of
                 this Agreement, the registered Holder of the Warrant shall
                 have the right, which may be exercised as set forth in the
                 Warrant Certificate, to purchase from the Company (and the
                 Company shall issue and sell to such registered Holder of the
                 Warrant) the number of fully paid and nonassessable Shares
                 specified in the Warrant Certificate, upon surrender to the
                 Company, or its duly authorized agent, of the Warrant
                 Certificate, with the form of election to purchase on the
                 reverse thereof duly filled in and signed, and upon payment to
                 the Company of the Exercise Price, as adjusted in accordance
                 with the provisions of Section 8 of this Agreement, for the
                 number of Shares in respect of which the Warrant is being
                 exercised; provided, however, that such purchase shall not be
                 for  fewer than the lesser of (i) 1,000 Shares or (ii) the
                 full number of Shares for which the Warrant is then
                 exercisable.  Payment of such Exercise Price may be made in
                 cash, wire transfer of funds or by certified or official bank
                 check payable to the order of the Company.  No adjustment
                 shall be made for any dividends on any Shares issuable upon
                 exercise of the  Warrant.  Upon the surrender of the Warrant
                 Certificate and payment of the Exercise Price as aforesaid,
                 the Company shall issue and cause to be delivered with
<PAGE>   3
                 all reasonable dispatch to or upon the written order of the
                 registered Holder of the Warrant and (subject to receipt of
                 evidence of compliance with the Securities Act in accordance
                 with the provisions of Section 12 of this Agreement) in such
                 name or names as such registered Holder may designate, a
                 certificate or certificates for the number of full Shares so
                 purchased upon the exercise of the Warrant, together with
                 cash, as provided in Section 11 of this Agreement, in respect
                 of any fractional Shares otherwise issuable upon such
                 surrender.  Such certificate or certificates shall be deemed
                 to have been issued and any person so designated to be named
                 therein shall be deemed to have become a holder of record of
                 such Shares as of the date of the surrender of the Warrant
                 Certificate and payment of the Exercise Price as aforesaid;
                 provided, however, that if, at the date of surrender of the
                 Warrant Certificates and payment of such Exercise Price, the
                 transfer books for the Shares shall be closed, the
                 certificates for the Shares in respect of which the Warrant is
                 then exercised shall be issuable as of the date on which such
                 books shall next be opened (whether before, on or after the
                 Expiration Date) and until such date the Company shall be
                 under no duty to deliver any certificate for such Shares;
                 provided, further, that the transfer books of record shall not
                 be closed at any  one time for a period longer than twenty
                 days unless otherwise required by law.  The rights of purchase
                 represented by the Warrant shall be exercisable at the
                 election of the Holder thereof, either in full or from time to
                 time in part and, in the event that the Warrant Certificate is
                 exercised in respect of less than all Shares purchasable on
                 such exercise at any time prior to the Expiration Date, a new
                 Warrant Certificate will be issued for the remaining number of
                 Shares specified in the Warrant Certificate so surrendered.

         All Warrant Certificates surrendered upon exercise of the Warrant
shall be canceled by the Company and disposed of in a manner satisfactory to
the Company.

5.                        Payment of Taxes.  The Company will pay all expenses
                 and taxes attributable to the issuance of Shares upon the
                 exercise of the Warrant; provided, however, that the Company
                 shall not be required to pay any tax or taxes which may be
                 payable in respect of any transfer involved in the issue of
                 the Warrant Certificate or delivery of any certificates for
                 Shares in a name other than that of the registered Holder of
                 the Warrant in respect of which such transfer of the Warrant
                 Certificate is to be made or Shares are to be issued, and the
                 Company shall not be required to issue or deliver such
                 certificates unless or until the person or persons requesting
                 the issuance thereof shall have paid to the Company the amount
                 of such tax or shall have established to the satisfaction of
                 the Company that such tax has been paid.

6.                        Mutilated or Missing Warrant.  In case that the
                 Warrant Certificate shall be mutilated, lost, stolen or
                 destroyed, the Company shall issue and deliver in exchange and
                 substitution for and upon cancellation of the mutilated
                 Warrant Certificate, or in lieu of and substitution for the
                 Warrant Certificate lost, stolen or destroyed, a new Warrant
                 Certificate of like tenor and representing an equivalent right
                 or interest, but only upon receipt of evidence reasonably
                 satisfactory to the Company of such loss, theft or destruction
                 of the Warrant Certificate and indemnity, if requested, also
                 reasonably satisfactory to the Company.  Applicants for such
                 substitute Warrant Certificate shall also comply with such
                 other reasonable regulations and pay such other reasonable
                 charges as the Company may prescribe.

7.                        Reservation of Shares.  The Company shall at all
                 times that the Warrant is exercisable reserve and keep
                 available free from preemptive rights, out of the aggregate of
                 its authorized and unissued Shares or its authorized and
                 issued Shares held in its treasury, a number of Shares
                 sufficient to provide for the exercise of the rights of
                 purchase represented by the outstanding Warrant.  The Company
                 covenants that all Shares which may be issued upon exercise of
                 the Warrant will be validly issued, fully paid and
                 nonassessable shares of the  Company.

8.                        Adjustments.  In the event that, prior to the
                 exercise of the Warrant, the outstanding Common Shares are
                 changed into or exchanged for a different number or kind of
                 interests of the Company or other securities of the Company or
                 a successor entity or the holder of Common Shares shall
                 receive additional Common Shares or other securities or
                 property of the Company or a successor entity, in each case by
                 reason of a merger, consolidation, reorganization,
                 recapitalization, reclassification, share dividend, share
                 split or other special distribution, combination of interests
                 or other similar event, an appropriate and equitable
                 adjustment in the number and kind of consideration issuable
                 upon exercise of the Warrant shall be made so that, after such
                 event, the Shares issuable upon exercise of the Warrant
                 (assuming the exercise of the Warrant in its entirety) shall
                 represent the same potential ownership interest in the Company
                 or successor entity immediately after such event as it
                 represents immediately before such event, or, if other
                 consideration is received by a holder of Common Shares, the
                 Holder of a Warrant will receive, upon exercise of the
                 Warrant, the same consideration it would have received if it
                 had exercised such Warrant immediately prior to the event or
                 action.  Such adjustment shall be made without change in the
                 total price applicable to exercise of the Warrant (except for
                 any change in the aggregate price resulting from rounding-off)
                 and with any necessary corresponding adjustment in the
                 purchase price per Share.  In no event shall the Shares
                 include any fractional interests, but any fractions resulting
                 from any such adjustments shall be rounded up to the nearest
                 whole interest.

         In case the Company shall sell and issue Common Shares or rights,
options, warrants or convertible or exchangeable securities containing the
right to subscribe for or purchase Common Shares, excluding any securities
(including options) issued to Trust Managers and employees pursuant to a share
incentive plan approved by the Board of Trust Managers) (collectively, except
as aforesaid, "Common Share Rights"), at a price per Common Share (determined,
in the case of Common Share Rights, by dividing (X) the total amount receivable
by the Company in consideration of the sale and issuance of such Common Share
Rights,  plus the total consideration payable to the Company upon exercise,
conversion or exchange thereof, by (Y) the total number of Common Shares
covered by such Common Share Rights) that is lower than $2.00, the Holder's
Exercise Price then in effect shall be multiplied by a fraction, the numerator
of which shall be the sum of (A) the number of Common Shares outstanding
immediately prior to such sale and issuance plus (B) the number of Common
Shares which the aggregate consideration received (determined as provided
below) for such sale or issuance would purchase at the Holder's Exercise Price
then in effect and the denominator of which shall be the number of Common
Shares outstanding immediately prior to such issuance plus the number of Common
Shares to be sold and issued or issuable upon exercise of such Common Share
Rights.  Such adjustment shall be made successively whenever such an issuance
is made.
<PAGE>   5
         For the purposes of any adjustment under this Section, the Common
Shares which are held by the holder of any Common Share Rights shall be deemed
to be issued and outstanding as of the date of such sale and issuance and the
consideration received by the Company therefor shall be deemed to be the
consideration or premiums stated in such Common Share Rights to be paid for the
Common Shares covered thereby.  In the case the Company shall sell and issue
Shares or Common Share Rights for a consideration consisting, in whole or in
part, of property other than cash or its equivalent, then in determining the
"price per Common Share" and the "consideration received by the Company" for
purposes of this Section, the value of such property shall be determined in
good faith by the Board of Trust Managers.  In case the Company shall sell and
issue Common Share Rights together with one or more other securities as part of
a unit at a price per unit, then in determining the "price per Common Share"
and the "consideration received by the  Company" for purposes of this Section,
the Board of Trust Managers shall determine, in good faith, the fair value of
the Common Share Rights then being sold as part of such unit.

9.                        Compliance with Legal and Governmental Requirements.
                 Before taking any action which would cause an adjustment of
                 the Shares issuable upon exercise of  the Warrant, the Company
                 shall take any corporate action which may, in the opinion of
                 its counsel (which may be counsel employed by the Company), be
                 necessary in order that the Company may validly and legally
                 issue fully paid and nonassessable Shares at the Exercise
                 Price as so adjusted.

         Upon the issuance of any Shares, the Company shall use its best
efforts to list such Shares on any and all securities exchanges on which Common
Shares are then listed.

10.                       Notice of Certain Events. In case at any time the
                 Company shall propose:

                 a.                        to fix a record date for the purpose
                                  of determining the holders of Shares who are
                                  entitled to receive any dividend or
                                  distribution (other than a regular periodic
                                  dividend or distribution payable in cash), or
                                  any right to subscribe for, purchase or
                                  otherwise acquire any shares of beneficial
                                  interest of any class or any other securities
                                  of the Company, or to receive any other
                                  rights;

                 b.                        to effect any reorganization of the
                                  Company, any reclassification or
                                  recapitalization of the shares of beneficial
                                  interest of the Company or any consolidation
                                  or merger involving the Company and any other
                                  person or any transfer of all or
                                  substantially all of the assets of the
                                  Company to any other person; or

                 c.                        to effect any liquidation,
                                  dissolution or winding up of the Company;

then, and in any one or more of such cases, the Company shall cause notice
thereof to be mailed to each Holder of a Warrant at such Holder's last address
as the same appears in the Warrant register at least 10 days (or such longer
period as may be required by law) prior to the date on which (i) the books of
the Company shall close, or a record date be taken, for such dividend,
distribution or right or (ii) such reorganization, reclassification,
recapitalization, consolidation, merger, transfer, liquidation, dissolution or
winding up shall be effective, as the case may be.  Failure to mail such notice
<PAGE>   6
or any defect therein shall not affect the validity of the transaction;
provided that the foregoing shall not limit or impair any liability that the
Company may have to the Investor for breaching this Agreement.

         The Holder shall not be, and shall not have any of the rights or
privileges of a shareholder of the Company unless and until, and except to the
extent that, Common Shares have been issued and delivered in accordance with
this Agreement.

11.                       Fractional Interests.  Notwithstanding any adjustment
                 pursuant to Section 8 in the number of Shares purchasable upon
                 the exercise of the Warrant, the Company shall not be required
                 to issue fractions of Shares upon exercise of the Warrant or
                 to distribute certificates that evidence fractional shares.
                 In lieu of fractional shares, the Company shall, at its
                 option, be entitled to pay to the Holder at the time the
                 Warrant is exercised as herein provided an amount in cash
                 equal to the same fraction of the then current market price of
                 a Common Share, such amount to be rounded to the nearest cent.

12.                       Restrictions on Dispositions.  Investor understands
                 that it and the Company are required to comply with the
                 Securities Act and any applicable state securities laws with
                 respect to the issuance of Shares upon the exercise of the
                 Warrant.  In connection therewith, Investor represents and
                 warrants to the Company that the Warrant is being obtained by
                 Investor for its own account and not with a view to the
                 distribution thereof within the meaning of the Securities Act,
                 and agrees that, as a condition to the Company's obligation to
                 issue Shares upon any exercise of the Warrant,  Investor will
                 not dispose of the Warrant or any Shares except pursuant to
                 (i) an effective registration statement under the Securities
                 Act, (ii) any available rule or exemption from registration
                 under the Securities Act permitting such disposition of
                 securities or (iii) an opinion of counsel, reasonably
                 satisfactory to counsel for the Company, that an exemption
                 from such registration is available.

13.                       Certificates to Bear Legends.  The Warrant shall
                 be subject to a stop-transfer order and the certificate or
                 certificates therefor shall bear the following legend:

                 "NEITHER THE WARRANT REPRESENTED BY THIS CERTIFICATE NOR THE
                 SECURITIES ISSUABLE UPON EXERCISE HEREOF HAVE BEEN REGISTERED
                 UNDER THE SECURITIES ACT OF 1933, AS AMENDED.  SUCH WARRANT
                 AND SECURITIES CANNOT BE OFFERED OR SOLD EXCEPT PURSUANT TO
                 (i) AN EFFECTIVE REGISTRATION STATEMENT, (ii) ANY AVAILABLE
                 RULE OR EXEMPTION FROM REGISTRATION UNDER SUCH ACT RELATING TO
                 THE DISPOSITION OF SECURITIES OR (iii) AN OPINION OF COUNSEL,
                 REASONABLY SATISFACTORY TO COUNSEL FOR THE TRUST, THAT AN
                 EXEMPTION FROM REGISTRATION UNDER SUCH ACT IS AVAILABLE.
<PAGE>   7
                 THE TRANSFER OR EXCHANGE OF THE WARRANT REPRESENTED BY THIS
                 CERTIFICATE IS RESTRICTED IN ACCORDANCE WITH THE WARRANT
                 AGREEMENT REFERRED TO HEREIN."

The Shares issued upon exercise of the Warrant shall be subject to a
stop-transfer order and the certificate or certificates evidencing any such
Shares or securities shall bear the following legend:

                 "THE SHARES [OR OTHER SECURITIES] REPRESENTED BY THIS
                 CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT
                 OF 1933, AS AMENDED.  SUCH SHARES [OR OTHER SECURITIES] CANNOT
                 BE OFFERED OR SOLD EXCEPT PURSUANT TO (i) AN EFFECTIVE
                 REGISTRATION STATEMENT, (ii) ANY AVAILABLE RULE OR EXEMPTION
                 FROM REGISTRATION UNDER SUCH ACT RELATING TO THE DISPOSITION
                 OF SECURITIES OR (iii) AN OPINION OF COUNSEL, REASONABLY
                 SATISFACTORY TO COUNSEL FOR THIS TRUST, THAT AN EXEMPTION FROM
                 REGISTRATION UNDER SUCH ACT IS AVAILABLE."

Certificates for the Warrant or Shares without legend shall be issued if the
Warrant or such Shares are sold pursuant to an effective registration statement
under the Securities Act or if the Company has received an opinion from
counsel, reasonably satisfactory to counsel for the Company, that such legend
is no longer required under the Securities Act.

14.                       Notices.  Any notice pursuant to this Agreement to be
                 given or made by the registered Holder of any Warrant to or on

                               WARRANT AGREEMENT

         This Warrant  Agreement, is made and entered into as of October 3,
1997, by and between American Industrial Properties REIT, a Texas real estate
investment trust (the "Company"), and AG Industrial Investors, L.P.,
("Investor").

         WHEREAS, the Company, AIP-SWAG Operating Partnership, L.P., a Delaware
limited partnership (the "Operating Partnership"), and Shidler West Investment
Corporation ("Shidler West"), acting on behalf of Investor and Shidler West
Acquisition Company, LLC, have entered into a Contribution and Exchange
Agreement, dated as of September 25, 1997 (the "Contribution Agreement"),
pursuant to which, among other things, the Operating Partnership agreed to
acquire the right to purchase certain real property from Shidler West; and

         WHEREAS, pursuant to the Contribution Agreement, the Company has
agreed to issue to Investor a warrant as hereinafter described (the "Warrant")
to purchase up to an aggregate of 100,000 (subject to adjustment as hereinafter
provided)  shares of beneficial interest, par value $0.10 per share (the
"Common Shares"), of the Company.

         NOW, THEREFORE, the parties hereto, in consideration of the foregoing,
the mutual covenants and agreements hereinafter set forth, and other good and
valuable consideration, the receipt and sufficiency of which hereby are
acknowledged, hereby agree as follows:

1.                        Form of Warrant.  The text of the Warrant certificate
                 and of the form of election to purchase Common Shares (as used
                 herein the term "Shares" refers to the Common Shares and,
                 where appropriate, such term shall also mean the other
                 securities or property purchasable upon the exercise of a
                 Warrant as provided for herein upon the happening of certain
                 events) shall be substantially as set forth in Exhibit A
                 attached hereto (the "Warrant Certificate"), which is hereby
                 incorporated by reference and made a part hereof.  The Warrant
                 Certificate shall be executed on behalf of the Company by an
                 appropriate officer of the Company.  Such signature may be in
                 the form of a facsimile thereof and may be impressed, affixed,
                 imprinted or otherwise reproduced on the Warrant Certificate.
                 The Warrant Certificate shall be dated the date of execution
                 by an appropriate officer of the Company either upon initial
                 issuance or upon any division, exchange, substitution or
                 transfer thereof that is permitted by this Agreement.

2.                        Registration.  The Warrant Certificate and any
                 certificates issued upon transfer or exchange of the Warrant
                 shall be numbered and shall be registered in a Warrant
                 register.  The Company shall be entitled to treat the
                 registered holder of any Warrant in the Warrant register (the
                 "Holder") as the owner in fact thereof for all purposes
                 (notwithstanding any notation of ownership or other writing
                 thereon made by anyone) and shall not be bound to recognize
                 any equitable or other claim to or interest in such Warrant on
                 the part of any other person, and shall not be liable for any
                 registration or transfer of a Warrant that is registered
<PAGE>   2
                 or to be registered in the name of a fiduciary or the nominee
                 of a fiduciary unless made with the actual knowledge that a
                 fiduciary or nominee is committing a breach of trust in
                 requesting such registration of transfer, or with knowledge of
                 such facts that its participation therein amounts to bad
                 faith.  The Warrant shall be registered initially in the name
                 of "AG Industrial Investors, L.P."

3.                        Transfer of Warrant. The Warrant shall be
                 transferable only on the books of the Company upon delivery of
                 the Warrant Certificate, duly endorsed by the Holder or by its
                 duly authorized attorney or representative, or accompanied by
                 proper evidence of succession, assignment or authority to
                 transfer.  In all cases of transfer by an attorney, the
                 original power of attorney, duly approved, or an official copy
                 thereof, duly certified, shall be deposited with the Company.
                 In case of transfer by executors, administrators, guardians or
                 other legal representatives, duly authenticated evidence of
                 their authority shall be produced, and may be required to be
                 deposited with the Company in its discretion.  Upon any
                 registration of transfer, the Company shall deliver a new
                 Warrant Certificate or Warrant Certificates to the person or
                 persons entitled thereto.  The Warrant Certificate may be
                 exchanged, at the option of the Holder thereof, for another
                 Warrant Certificate, or other Warrant Certificates of
                 different denominations, of like tenor and representing in the
                 aggregate the right to purchase a like number of Shares upon
                 surrender of the Warrant Certificate to the Company or its
                 duly authorized agent.  Notwithstanding the foregoing, the
                 Company shall have no obligation to cause a Warrant to be
                 transferred on its books to any person unless the Holder of
                 such Warrant shall furnish to the Company evidence of
                 compliance with the Securities Act of 1933, as amended (the "
                 Securities Act "), in accordance with the terms of the legend
                 set forth in Section 13 of this Agreement.  The Company shall
                 cancel and dispose of Warrant Certificates surrendered for
                 exchange or for registration of transfer in a manner
                 satisfactory to the Company.

4.                        Term of Warrant; Exercise of Warrant.  The Warrant
                 entitles the registered owner thereof to purchase up to
                 100,000 Common Shares at a purchase price of $3.50 per share
                 (the "Exercise Price") at any time after the date hereof and
                 on and before 5:00 p.m. Central Time on October 3, 2000 (the
                 "Expiration Date").  The Exercise Price and the Shares
                 issuable upon exercise of the Warrant are subject to
                 adjustment upon the occurrence of certain events specified in
                 Section 8 of this Agreement.  Subject to the provisions of
                 this Agreement, the registered Holder of the Warrant shall
                 have the right, which may be exercised as set forth in the
                 Warrant Certificate, to purchase from the Company (and the
                 Company shall issue and sell to such registered Holder of the
                 Warrant) the number of fully paid and nonassessable Shares
                 specified in the Warrant Certificate, upon surrender to the
                 Company, or its duly authorized agent, of the Warrant
                 Certificate, with the form of election to purchase on the
                 reverse thereof duly filled in and signed, and upon payment to
                 the Company of the Exercise Price, as adjusted in accordance
                 with the provisions of Section 8 of this Agreement, for the
                 number of Shares in respect of which the Warrant is being
                 exercised; provided, however, that such purchase shall not be
                 for  fewer than the lesser of (i) 1,000  Shares or (ii) the
                 full number of Shares for which the Warrant is then
                 exercisable.   Payment of such Exercise Price may be
<PAGE>   3
                 made in cash, wire transfer of funds or by certified or
                 official bank check payable to the order of the Company.  No
                 adjustment shall be made for any dividends on any Shares
                 issuable upon exercise of the Warrant.  Upon the surrender of
                 the Warrant Certificate and payment of the Exercise Price as
                 aforesaid, the Company shall issue and cause to be delivered
                 with all reasonable dispatch to or upon the written order of
                 the registered Holder of the Warrant and (subject to receipt
                 of evidence of compliance with the Securities Act in
                 accordance with the provisions of Section 12 of this
                 Agreement) in such name or names as such registered Holder may
                 designate, a certificate or certificates for the number of
                 full Shares so purchased upon the exercise of the Warrant,
                 together with cash, as provided in Section 11 of this
                 Agreement, in respect of any fractional Shares otherwise
                 issuable upon such surrender.  Such certificate or
                 certificates shall be deemed to have been issued and any
                 person so designated to be named therein shall be deemed to
                 have become a holder of record of such Shares as of the date
                 of the surrender of the Warrant Certificate and payment of the
                 Exercise Price as aforesaid; provided, however, that if, at
                 the date of surrender of the Warrant Certificates and payment
                 of such Exercise Price, the transfer books for the Shares
                 shall be closed, the certificates for the Shares in respect of
                 which the Warrant is then exercised shall be issuable as of
                 the date on which such books shall next be opened (whether
                 before, on or after the Expiration Date) and until such date
                 the Company shall be under no duty to deliver any certificate
                 for such Shares; provided, further, that the transfer books of
                 record shall not be closed at any  one time for a period
                 longer than twenty days unless otherwise required by law.  The
                 rights of purchase represented by the Warrant shall be
                 exercisable at the election of the Holder thereof, either in
                 full or from time to time in part and, in the event that the
                 Warrant Certificate is exercised in respect of less than all
                 Shares purchasable on such exercise at any time prior to the
                 Expiration Date, a new Warrant Certificate will be issued for
                 the remaining number of Shares specified in the Warrant
                 Certificate so surrendered.

         All Warrant Certificates surrendered upon exercise of the Warrant
shall be canceled by the Company and disposed of in a manner satisfactory to
the Company.

5.                        Payment of Taxes.  The Company will pay all expenses
                 and taxes attributable to the issuance of Shares upon the
                 exercise of the Warrant; provided, however, that the Company
                 shall not be required to pay any tax or taxes which may be
                 payable in respect of any transfer involved in the issue of
                 the Warrant Certificate or delivery of any certificates for
                 Shares in a name other than that of the registered Holder of
                 the Warrant in respect of which such transfer of the Warrant
                 Certificate is to be made or Shares are to be issued, and the
                 Company shall not be required to issue or deliver such
                 certificates unless or until the person or persons requesting
                 the issuance thereof shall have paid to the Company the amount
                 of such tax or shall have established to the satisfaction of
                 the Company that such tax has been paid.

6.                        Mutilated or Missing Warrant.  In case that the
                 Warrant Certificate shall be mutilated, lost, stolen or
                 destroyed, the Company shall issue and deliver in exchange and
                 substitution for and upon cancellation of the mutilated
                 Warrant Certificate, or in lieu of and substitution for the
                 Warrant Certificate lost, stolen or destroyed, a new Warrant
                 Certificate of like tenor
<PAGE>   4
                 and representing an equivalent right or interest, but only
                 upon receipt of evidence reasonably satisfactory to the
                 Company of such loss, theft or destruction of the Warrant
                 Certificate and indemnity, if requested, also reasonably
                 satisfactory to the Company.  Applicants for such substitute
                 Warrant Certificate shall also comply with such other
                 reasonable regulations and pay such other reasonable charges
                 as the Company may prescribe.

7.                        Reservation of Shares.  The Company shall at all
                 times that the Warrant is exercisable reserve and keep
                 available free from preemptive rights, out of the aggregate of
                 its authorized and unissued Shares or its authorized and
                 issued Shares held in its treasury, a number of Shares
                 sufficient to provide for the exercise of the rights of
                 purchase represented by the outstanding Warrant.  The Company
                 covenants that all Shares which may be issued upon exercise of
                 the Warrant will be validly issued, fully paid and
                 nonassessable shares of the Company.

8.                        Adjustments.  In the event that, prior to the
                 exercise of the Warrant, the outstanding Common Shares are
                 changed into or exchanged for a different number or kind of
                 interests of the Company or other securities of the Company or
                 a successor entity or the holder of Common Shares shall
                 receive additional Common Shares or other securities or
                 property of the Company or a successor entity, in each case by
                 reason of a merger, consolidation, reorganization,
                 recapitalization, reclassification, share dividend, share
                 split or other special distribution, combination of interests
                 or other similar event, an appropriate and equitable
                 adjustment in the number and kind of consideration issuable
                 upon exercise of the Warrant shall be made so that, after such
                 event, the Shares issuable upon exercise of the Warrant
                 (assuming the exercise of the Warrant in its entirety) shall
                 represent the same potential ownership interest in the Company
                 or successor entity immediately after such event as it
                 represents immediately before such event, or, if other
                 consideration is received by a holder of Common Shares, the
                 Holder of a Warrant will receive, upon exercise of the
                 Warrant, the same consideration it would have received if it
                 had exercised such Warrant immediately prior to the event or
                 action.  Such adjustment shall be made without change in the
                 total price applicable to exercise of the Warrant (except for
                 any change in the aggregate price resulting from rounding-off)
                 and with any necessary corresponding adjustment in the
                 purchase price per Share.  In no event shall the Shares
                 include any fractional interests, but any fractions resulting
                 from any such adjustments shall be rounded up to the nearest
                 whole interest.

         In case the Company shall sell and issue Common Shares or rights,
options, warrants or convertible or exchangeable securities containing the
right to subscribe for or purchase Common Shares, excluding any securities
(including options) issued to Trust Managers and employees pursuant to a share
incentive plan approved by the Board of Trust Managers) (collectively, except
as aforesaid, "Common Share Rights"), at a price per Common Share (determined,
in the case of Common Share Rights, by dividing (X) the total amount receivable
by the Company in consideration of the sale and issuance of such Common Share
Rights,  plus the total consideration payable to the Company upon exercise,
conversion or exchange thereof, by (Y) the total number of Common Shares
covered by such Common Share Rights) that is lower than $2.00, the Holder's
Exercise Price
<PAGE>   5
then in effect shall be multiplied by a fraction, the numerator of which shall
be the sum of (A) the number of Common Shares outstanding immediately prior to
such sale and issuance plus (B) the number of Common Shares which the aggregate
consideration received (determined as provided below) for such sale or issuance
would purchase at the Holder's Exercise Price then in effect and the
denominator of which shall be the number of Common Shares outstanding
immediately prior to such issuance plus the number of Common Shares to be sold
and issued or issuable upon exercise of such Common Share Rights.  Such
adjustment shall be made successively whenever such an issuance is made.

         For the purposes of any adjustment under this Section, the Common
Shares which are held by the holder of any Common Share Rights shall be deemed
to be issued and outstanding as of the date of such sale and issuance and the
consideration received by the Company therefor shall be deemed to be the
consideration or premiums stated in such Common Share Rights to be paid for the
Common Shares covered thereby.  In the case the Company shall sell and issue
Shares or Common Share Rights for a consideration consisting, in whole or in
part, of property other than cash or its equivalent, then in determining the
"price per Common Share" and the "consideration received by the Company" for
purposes of this Section, the value of such property shall be determined in
good faith by the Board of Trust Managers.  In case the Company shall sell and
issue Common Share Rights together with one or more other securities as part of
a unit at a price per unit, then in determining the "price per Common Share"
and the "consideration received by the  Company" for purposes of this Section,
the Board of Trust Managers shall determine, in good faith, the fair value of
the Common Share Rights then being sold as part of such unit.

9.                        Compliance with Legal and Governmental Requirements.
                 Before taking any action which would cause an adjustment of
                 the Shares issuable upon exercise of  the Warrant, the Company
                 shall take any corporate action which may, in the opinion of
                 its counsel (which may be counsel employed by the Company), be
                 necessary in order that the Company may validly and legally
                 issue fully paid and nonassessable Shares at the Exercise
                 Price as so adjusted.

         Upon the issuance of any Shares, the Company shall use its best
efforts to list such Shares on any and all securities exchanges on which Common
Shares are then listed.

10.                       Notice of Certain Events. In case at any time the
                 Company shall propose:

                 a.                        to fix a record date for the purpose
                                  of determining the holders of Shares who are
                                  entitled to receive any dividend or
                                  distribution (other than a regular periodic
                                  dividend or distribution payable in cash), or
                                  any right to subscribe for, purchase or
                                  otherwise acquire any shares of beneficial
                                  interest of any class or any other securities
                                  of the Company, or to receive any other
                                  rights;

                 b.                        to effect any reorganization of the
                                  Company, any reclassification or
                                  recapitalization of the shares of beneficial
                                  interest of the Company or any
<PAGE>   6
                                  consolidation or merger involving the Company
                                  and any other person or any transfer of all
                                  or substantially all of the assets of the
                                  Company to any other person; or

                 c.                        to effect any liquidation, 
                                  dissolution or winding up of the Company;

then, and in any one or more of such cases, the Company shall cause notice
thereof to be mailed to each Holder of a Warrant at such Holder's last address
as the same appears in the Warrant register at least 10 days (or such longer
period as may be required by law) prior to the date on which (i) the books of
the Company shall close, or a record date be taken, for such dividend,
distribution or right or (ii) such reorganization, reclassification,
recapitalization, consolidation, merger, transfer, liquidation, dissolution or
winding up shall be effective, as the case may be.  Failure to mail such notice
or any defect therein shall not affect the validity of the transaction;
provided that the foregoing shall not limit or impair any liability that the
Company may have to the Investor for breaching this Agreement.

         The Holder shall not be, and shall not have any of the rights or
privileges of a shareholder of the Company unless and until, and except to the
extent that, Common Shares have been issued and delivered in accordance with
this Agreement.

11.                       Fractional Interests.  Notwithstanding any adjustment
                 pursuant to Section 8 in the number of Shares purchasable upon
                 the exercise of the Warrant, the Company shall not be required
                 to issue fractions of Shares upon exercise of the Warrant or
                 to distribute certificates that evidence fractional shares.
                 In lieu of fractional shares, the Company shall, at its
                 option, be entitled to pay to the Holder at the time the
                 Warrant is exercised as herein provided an amount in cash
                 equal to the same fraction of the then current market price of
                 a Common Share, such amount to be rounded to the nearest cent.

12.                       Restrictions on Dispositions.  Investor understands
                 that it and the Company are required to comply with the
                 Securities Act and any applicable state securities laws with
                 respect to the issuance of Shares upon the exercise of the
                 Warrant.  In connection therewith, Investor represents and
                 warrants to the Company that the Warrant is being obtained by
                 Investor for its own account and not with a view to the
                 distribution thereof within the meaning of the Securities Act,
                 and agrees that, as a condition to the Company's obligation to
                 issue Shares upon any exercise of the Warrant,  Investor will
                 not dispose of the Warrant or any Shares except pursuant to
                 (i) an effective registration statement under the Securities
                 Act, (ii) any available rule or exemption from registration
                 under the Securities Act permitting such disposition of
                 securities or (iii) an opinion of counsel, reasonably
                 satisfactory to counsel for the Company, that an exemption
                 from such registration is available.

13.                       Certificates to Bear Legends.  The Warrant shall
                 be subject to a stop-transfer order and the certificate or
                 certificates therefor shall bear the following legend:
<PAGE>   7

The Shares issued upon exercise of the Warrant shall be subject to a
stop-transfer order and the certificate or certificates evidencing any such
Shares or securities shall bear the following legend:

Certificates for the Warrant or Shares without legend shall be issued if the
Warrant or such Shares are sold pursuant to an effective registration statement
under the Securities Act or if the Company has received an opinion from
counsel, reasonably satisfactory to counsel for the Company, that such legend
is no longer required under the Securities Act.

                         REGISTRATION RIGHTS AGREEMENT

                 This Registration Rights Agreement (the "Agreement") is made
and entered into as of October 3, 1997, by and among American Industrial
Properties REIT, a Texas real estate investment trust (the "Company"), and
Shidler West Acquisition Company, LLC, a California limited liability company
(the "Investor").

         WHEREAS, the Company, AIP-SWAG Operating Partnership, L.P., a Delaware
limited partnership (the "Operating Partnership"), and Shidler West Investment
Corporation ("Shidler West"), acting on behalf of  the Investor and AG
Industrial Investors, L.P., have entered into a Contribution and Exchange

pursuant to which, among other things, the Operating Partnership agreed to

interest, par value $.10 per share, of the Company (the "Common Shares"), and
(ii) a warrant to purchase up to an aggregate amount of 100,000 Common Shares
(the "Warrant Shares," and  together with the Converted Shares, the "Shares");
and

         WHEREAS, pursuant to the terms of the Contribution Agreement, the
Company and the Investor agreed that the Company would grant certain
registration rights to the Investor;

                 NOW, THEREFORE, for valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the parties hereto agree as

                 Person: An individual, partnership,  corporation, limited
liability company, trust or unincorporated organization, or a government or
agency or political subdivision thereof.

                 Prospectus: The prospectus included in any Registration
Statement, as amended or supplemented by any prospectus supplement with respect
to the terms of the offering of any portion of the Registrable Securities
covered by such Registration Statement and by all other amendments and
supplements to the prospectus, including post-effective amendments and all
material incorporated by reference in such prospectus.
<PAGE>   2
                 Registrable Securities: (a) The Shares and (b) any securities
issued or issuable with respect to the Shares by way of stock dividend or stock
split or in connection with a combination of shares, recapitalization, merger,
consolidation or other reorganization or otherwise.  Any Registrable Security
will cease to be a Registrable Security when (i) a registration statement
covering such Registrable Security has been declared effective by the SEC and
the Registrable Security has been disposed of pursuant to such effective
registration statement; (ii) the Registrable Security has been sold pursuant to
Rule l44 or any other valid exemption from registration; or (iii) the
Registrable Security has been otherwise transferred, the Company has delivered
a new certificate or other evidence of ownership for it not bearing a legend
restricting further transfer, and it may be resold by the holder thereof
without subsequent registration under the Securities Act.

                 Registration Statement: A Registration Statement of the
Company that covers any of the Registrable Securities pursuant to the
provisions of this Agreement, including the Prospectus included therein, all
amendments and supplements to such Registration Statement or Prospectus,

                 Rule 144:  Rule 144 under the Securities Act, as such Rule may

entity.

                 Securities Act: The Securities Act of 1933, as amended.

                 Underwritten Registration or Underwritten Offering: A
registration under the Securities Act in which securities of the Company are
sold to an underwriter for reoffering to the public.

         2.      Demand Registration.

                 (a)      Requests for Registration.  At any time after the
second anniversary  (the first anniversary with respect to the Warrant Shares)
of the Closing Date, the Investor may make a written request (the "Demand
Notice") for registration under the Securities Act (a "Demand Registration") of
the number of  Registrable Securities requested to be registered pursuant to
the terms of this Agreement. The Demand Notice will specify the number of
shares of Registrable Securities proposed to be sold and will also specify the
intended method of disposition thereof.  Following receipt of a Demand Notice
from the Investor, the Company promptly will file a Registration Statement on
any appropriate form that will cover the Registrable Securities that the
Company has been so requested to register by the Investor.

         The Company shall not be required to effect more than one Demand
Registration under this Section 2.  A registration requested pursuant to this
Section 2 will not be deemed to have been effected unless the Registration
Statement relating thereto has become effective under the Securities Act;
provided, however that if, after such Registration Statement has become
effective, the offering of the Registrable Securities pursuant to such
registration is interfered with by any stop order,
<PAGE>   3
injunction or other order or requirement of the SEC or other governmental
agency or court, such registration will be deemed not to have been effected.

         If the Investor requests that a Demand Registration be a "shelf"
registration pursuant to Rule 415 under the Securities Act, the Company shall
file the Demand Registration under Rule 415 and shall keep the Registration
Statement filed in respect thereof effective for a period that will terminate
on the earlier of (i) 180 days from the date on which the SEC declares such
Registration Statement effective and (ii) the date on which all Registrable
Securities covered by such Registration Statement have been sold pursuant to
such Registration Statement; provided that such 180 day period shall be tolled
during the period that the Investor is required to discontinue disposition of
Registrable Securities pursuant to the last paragraph of Section 4.

                 (b)      Additional Shares.  The parties agree that any
Registration Statement may register shares that are not Registrable Securities,
but (i) are proposed to be sold by the Company or (ii) are Common Shares held
by other Persons, or to be issued to other Persons, and subject to registration
rights.

                 (c)      Priority on Registration.  If any of the Registrable
Securities registered pursuant to a Demand Registration are to be sold in an
Underwritten Offering, and the managing underwriter or underwriters of such
offering advise the Company and the Investor in writing that in their opinion
the total number of shares or dollar amount of Registrable Securities proposed
to be sold in such offering is sufficiently large to materially and adversely
affect the success of such offering, the Company will include in such
registration the aggregate number or dollar amount of Registrable Securities
that in the opinion of such managing underwriter or underwriters can be sold
without any such material adverse effect; provided, however, that no
Registrable Securities, if any, may be excluded before all shares proposed to
be sold by other parties, including the Company, have been excluded.  If any
Registrable Securities are excluded, such registration shall not count as one
of the two Demand Registrations.

                 (d)      Postponement of Registration.  The Company shall be
entitled to postpone, for a reasonable period of time not in excess of 90 days
during any 365-day period, the filing of a Registration Statement if the
Company determines, in the good faith exercise of its reasonable business
judgment, that such registration and offering could adversely affect or
interfere with bona fide financing plans of the Company or any of its
affiliates or would require disclosure of information, the premature disclosure
of which could adversely affect the Company or any transaction under
consideration by the Company.
<PAGE>   4
         3.      Piggyback Registration

                 (a)      Right to Piggyback.  If at any time the Company
proposes to file a registration statement under the Securities Act with respect
to an offering of Common Shares (other than a registration statement (i) on
Form S-4 or Form S-8 or any successor forms thereto or  to register for resale
any securities awarded pursuant to an unregistered offering to the Company's
employees or Trust Managers, or to employees of its subsidiaries, pursuant to
any employee benefit plan (as defined in Rule 405 under the Securities Act),
(ii) in connection with an exchange offer, or (iii) in connection with the
acquisition of assets by the Company, the Operating Partnership or any of their
affiliates), whether or not for its own account, then the Company shall give
written notice of such proposed filing to the Investor at least 30 days before
the anticipated filing date.  Such notice shall offer the Investor  the
opportunity to register such amount of Registrable Securities as the Investor
may request (a "Piggyback Registration").  Subject to Section 3(b) hereof, the
Company shall include in each such Piggyback Registration all Registrable
Securities with respect to which the Company has received a written request for
inclusion therein within 10 days after notice has been given to the Investor
(which  request shall specify the intended method of distribution).  The
Investor  shall be permitted to withdraw all or part of the Registrable
Securities from a Piggyback Registration at any time prior to the effective
date of such Piggyback Registration.  The Company shall not be required to
effect more than two Piggyback Registrations under this Section 3.

         (b)     Priority on Piggyback Registrations.  The Company shall cause
the managing underwriter of a proposed Underwritten Offering to include all
such Registrable Securities on the same terms and conditions as any other
Common Shares, if any, of the Company included therein.  Notwithstanding the
foregoing, if the managing underwriter of such Underwritten Offering delivers
an opinion to the Investor that the total number or dollar amount of securities
that the Investor, the Company and other Persons having rights to participate
in such registration, propose to include in such offering is such as to
materially and adversely affect the success of such offering, then the amount
of Common Shares to be offered (i) for the account of Investor and (ii) for the
account of all such other Persons (other than the Company) shall be reduced or
limited pro rata in proportion to the respective dollar amounts of  Common
Shares requested by such persons to be included in such offering.

         4.      Hold-Back Agreements.

                 (a)      Restrictions on Public Sale by Holder of Registrable
Securities.  So long as the Investor holds Registrable Securities, the Investor
agrees, in connection with any sale of securities by the Company and in
connection with any Registration Statement filed pursuant to Section 2 or 3, if
requested by the Company or the managing underwriters in an Underwritten
Offering, not to effect any public sale or distribution of securities of the
Company, including a sale pursuant to Rule 144 (except as part of such
Underwritten Offering), during the 10-day period prior to, and during the
90-day period beginning on, the closing date of each offering made by the
Company or pursuant to such Registration Statement, to the extent timely
notified in writing by the Company or the managing underwriters; provided that
such restrictions shall not be more restrictive in duration or scope than
restrictions imposed on (i) any Person which has been granted registration
rights by the Company (other than the "Majority Shareholders"), (ii) any
officer or director of the
<PAGE>   5

Company or (iii) any 5% holder of Common Shares of the Company (other than the
"Majority Shareholders").

                 (b)      Restrictions on Sale of Securities by the Company.
So long as the Investor holds Registrable Securities, the Company agrees that,
without the written consent of the managing underwriter or underwriters in an
Underwritten Offering of Registrable Securities covered by a Registration
Statement filed pursuant to Section 2 or 3, not to effect any public sale or
distribution of any securities similar to those being registered, or any
securities convertible into or exchangeable or exercisable for such securities
during the 10-day period prior to, and the 90-day period beginning on, the
closing date of each Underwritten Offering (except (w) as part of such
Underwritten Offering, (x)  pursuant to registrations on Form S-4 or Form S-8
or any successor form to such forms or  to register for resale any securities
awarded pursuant to an offering to the Company's employees or Trust Managers,
or to employees of its subsidiaries, pursuant to any employee benefit plan (as
defined in Rule 405 under the Securities Act), (y) in connection with an
exchange offer or (z) in connection with the acquisition of assets by the
Company, the Operating Partnership or any of their affiliates).

         5.      Registration Procedures.  In connection with the Company's
registration obligations pursuant to Section 2 or 3 hereof, the Company will
use its commercially reasonable efforts to effect such registration to permit
the sale of such Registrable Securities in accordance with the intended method
or methods of distribution thereof, and pursuant thereto the Company will use
commercially reasonable efforts to as expeditiously as possible:

                 (a)      prepare and file with the SEC, as soon as
practicable, a Registration Statement relating to the applicable registration
on any appropriate form under the Securities Act that shall be available for
the sale of the Registrable Securities in accordance with the intended method
or methods of distribution thereof, and use its commercially reasonable efforts
to cause such Registration Statement to become effective; provided that before
filing a Registration Statement or Prospectus or any amendments or supplements
thereto, including documents incorporated by reference after the initial filing
of the Registration Statement, the Company will furnish the Investor and the
underwriters, if any, copies of all such documents proposed to be filed, which
documents will be subject to the review of the Investor and the underwriters,
if any; provided, further, that the Company shall not be required to deliver to
the Investor or the underwriters a copy of any such document that has not been
materially changed from a copy of such document that was previously delivered
to the Investor and the underwriters.  The Company will not file any
Registration Statement or amendment thereto or any Prospectus or any supplement
thereto (including such documents incorporated by reference) to which the
Investor or the underwriters, if any, shall reasonably object, in writing, on a
timely basis, unless, in the opinion of the Company, such filing is necessary
to comply with applicable law;

                 (b)      prepare and file with the SEC such amendments and
post-effective amendments to the Registration Statement as may be necessary to
keep the Registration Statement effective for the applicable period, or such
shorter period which will terminate when all Registrable Securities included in
such Registration Statement have been sold; cause the Prospectus to be
<PAGE>   6
supplemented by any required Prospectus supplement, and as so supplemented to
be filed pursuant to Rule 424 under the Securities Act;

                 (c)      notify the Investor and the managing underwriters, if
any, promptly, and (if requested by any such Person) confirm such advice in
writing, (l) when the Registration Statement, the Prospectus or any Prospectus

Registration Statement or any post-effective amendment thereto, when the same
has become effective, (2) of any request by the SEC for amendments or
supplements to the Registration Statement or the Prospectus or for additional
information (provided that the Company shall not be required to notify the
Investor of all "comment" letters received by the Company from the SEC or to
deliver copies of such comment letters or the Company's responses thereto to
the Investor unless such letters request information from or about the
Investor), (3) of the issuance by the SEC of any stop order suspending the
effectiveness of the Registration Statement or the initiation of any
proceedings for that purpose, (4) if at any time the representations and
warranties of the Company contemplated by Section 5(m)(1) below cease to be
true and correct, (5) of the receipt by the Company of any notification with
respect to the suspension of the qualification of the Registrable Securities
for sale in any jurisdiction or the initiation or threatening of any proceeding
for such purpose and (6) of the happening of any event which makes any
statement made in the Registration Statement, the Prospectus or any document
incorporated therein by reference untrue in any material respect or that
requires the making of any changes in the Registration Statement, the
Prospectus or any document incorporated therein by reference so that, in the
case of the Registration Statement, it will not contain any untrue statement of
a material fact or omit to state any material fact required to be stated
therein or necessary to make the statements therein not misleading, and that,
in the case of the Prospectus, it will not contain any untrue statement of a
material fact or omit to state any material fact necessary in order to make the
statements therein, in light of the circumstances under which they were made,
not misleading;

                 (d)      obtain the withdrawal of any order suspending the
effectiveness of the Registration Statement;

                 (e)      if requested by the managing underwriter or
underwriters or by the Investor, promptly incorporate in a Prospectus
supplement or post-effective amendment to the Registration Statement such
information as the managing underwriters and the Investor reasonably request in
order to permit the intended method of distribution of such securities and make
all required filings of such Prospectus supplement or post-effective amendment
as soon as practicable after the Company has received such request; provided,
however, that the Company shall not be required to take any actions under this
Section 5(e) that are not in compliance with applicable law;

                 (f)      furnish to the Investor and each managing
underwriter, if any, without charge, at least one signed copy of the

supplement thereto by the Investor and the underwriters, if any, in connection
with the offering and sale of the Registrable Securities covered by the
Prospectus or any amendment or supplement thereto;

                 (h)      prior to any public offering of Registrable
Securities, register or qualify or cooperate with the Investor, the
underwriters, if any, and their respective counsel in connection with the
registration or qualification of such Registrable Securities for offer and sale
under the securities or blue sky laws of such jurisdictions within the United
States as the Investor or any underwriter reasonably requests in writing and do
any and all other acts or things necessary or advisable to enable the
disposition in such jurisdictions of the Registrable Securities covered by the
Registration Statement; provided, however, that the Company will not be
required to (A) qualify generally to do business in any jurisdiction where it
not then so qualified or (B) take any action that would subject the Company to
general service of process or to taxation in any such jurisdiction where it is
not then so subject;

                 (i)      cooperate with the Investor and the managing
underwriters, if any, to facilitate the timely preparation and delivery of

restrictive legends; and enable such Registrable Securities to be in such
denominations and registered in such names as the managing underwriters may
request at least two business days prior to any sale of Registrable Securities
to the underwriters;

                 (j)      cause the Registrable Securities covered by the
applicable Registration Statement to be registered with or approved by such
other governmental agencies or authorities as may be necessary to enable the
Investor or the underwriters, if any, to consummate the disposition of such
Registrable Securities;

                 (k)      upon the occurrence of any event contemplated by
Section 5(c)(6) above, prepare a supplement or post-effective amendment to the
Registration Statement or the related Prospectus or any document incorporated
therein by reference or file any other required document so that, as thereafter
delivered to the purchasers of the Registrable Securities, the Prospectus will
not contain an untrue statement of a material fact or omit to state any
material fact required to be stated therein or necessary to make the statements
therein, in light of the circumstances under which they  were made, not
misleading;

Registration Statement to be listed on each securities exchange on which
similar securities issued by the Company are then listed;

                 (m)      enter into such agreements (including an underwriting
agreement in form, scope and substance as is customary in underwritten
offerings) and take all such other actions reasonably requested by the Investor
or the managing underwriter or underwriters, if any, in order to expedite or
facilitate the disposition of such Registrable Securities and in connection
therewith, whether or not an underwriting agreement is entered into and whether
or not the registration is an Underwritten Registration, (1) make such

in form, substance and scope as are customarily made by issuers to underwriters
<PAGE>   8

Company and updates thereof (which counsel and opinions (in form, scope and
substance) shall be reasonably satisfactory to the Investor and the managing
underwriters, if any, covering the matters customarily covered in opinions
requested in Underwritten Offerings and such other matters as may be reasonably
requested by the Investor and the underwriters, if any; (3) obtain "cold
comfort" letters and updates thereof from the Company's independent certified
public accountants addressed to the Investor and the underwriters, if any, such

Underwritten Offerings (unless such accountants shall be prohibited from so
addressing such letters by applicable standards of the accounting profession);
(4) if an underwriting agreement is entered into, the same shall contain the
indemnification provisions and procedures substantially to the effect set forth
in Section 7 hereof with respect to all parties to be indemnified pursuant to
said Section; and (5) deliver such documents and certificates as may be
reasonably requested by the Investor and the managing underwriters, if any, to

contained in the underwriting agreement or other agreement entered into by the
Company.  The above shall be done at each closing under such underwriting or
similar agreement or as and to the extent required thereunder;

                 (n)      make available for inspection by a representative of
the Investor, any underwriter participating in any disposition pursuant to such
registration, and any attorney or accountant retained by the Investor or any
underwriter, at the offices where normally kept, during reasonable business
hours, all financial and other records, pertinent corporate documents and
properties of the Company and cause the Company's officers, trust managers and
employees to supply all information reasonably requested by any such
representative, underwriter, attorney or accountant in connection with such
registration; provided that any records, information or documents that the
Company designates in writing as confidential shall be kept confidential by
such Persons unless disclosure of such records, information or documents is
required by court or administrative order.  Without limiting the foregoing, no
such information shall be used by such Person as the basis for any market
transactions in securities of the Company or its subsidiaries in violation of
law;

                 (o)      otherwise comply with all applicable rules and
regulations of the SEC, and make available to its security holders, as soon as
reasonably practicable, an earnings statement covering a period of 12 months,
beginning within three months after the effective date of the Registration

11(a) of the Securities Act; and

                 (p)      cooperate with the Investor and each underwriter
participating in the disposition of such Registrable Securities and their
respective counsel in connection with any filings required to be made with the
National Association of Securities Dealers, Inc. (the "NASD").

         The Company may require the Investor to furnish to the Company such
information regarding the distribution of Registrable Securities as the Company
may from time to time reasonably request in writing, and the Company may
exclude from such registration the Registrable Securities of the Investor if it
unreasonably fails to furnish such information within a reasonable time after
receiving such request.
<PAGE>   9
         The Investor agrees by acquisition of the Registrable Securities that,
upon receipt of any notice from the Company of the happening of any event of
the kind described in Section 5(c) (2), 5(c)(3), 5(c)(5) and 5(c)(6) hereof,

writing by the Company that the use of the Prospectus may be resumed, and has
received copies of any additional or supplemental filings which are
incorporated by reference in the Prospectus, and, if so directed by the
Company, the Investor will deliver to the Company (at the Company's expense),
all copies, other than permanent file copies then in the Investor's possession,
of the Prospectus covering such Registrable Securities current at the time of
receipt of such notice.

regardless of whether the Registration Statement becomes effective. The Company
shall not have any obligation to pay (i) any underwriting fees, discounts or
commissions attributable to the sale of Registrable Securities, (ii) any legal
fees and expenses of counsel to the Investor or underwriters, except as
expressly provided herein, or (iii) any fees and expenses of any "qualified

confirmation of the sale by the Investor of a Registrable Security to the
Person asserting the claim from which such Losses arise and (ii) the Prospectus
would have corrected in all material respects such untrue statement or alleged
untrue statement or such omission or alleged omission; provided, further, that
the Company shall not be liable in any such case to the extent that any such
Losses arise out or are based upon an untrue statement or alleged untrue
statement or omission or alleged omission in the Prospectus, if (x) such untrue
statement or alleged untrue statement, omission or alleged omission is
corrected in all material respects in an amendment or supplement in the
Prospectus and (y) having previously been furnished by or on behalf of the
Company with copies of the Prospectus as so amended or supplemented, the
Investor thereafter fails to deliver such Prospectus as so amended or
supplemented, prior to or concurrently with the sale of a Registrable Security
to the Person asserting the claim for which such Losses arise.

                 (b)      Indemnification By Holder of Registrable Securities.
The Investor agrees to indemnify and hold harmless the Company and its
partners, trust managers, officers, employees and agents, and each Person who
controls any such Persons (within the meaning of Section 15 of the Securities
Act or Section 20 of the Exchange Act) (collectively, the "Company") against
all Losses arising out of or based upon  any untrue statement of a material
fact contained in any Registration Statement, Prospectus or preliminary
prospectus or any omission or alleged omission to state therein a material fact
required to be stated therein or necessary to make the statements therein not
misleading, to the extent, but only to the extent, that such untrue statement
or omission is contained in any information or affidavit so furnished in
writing by the Investor to the Company specifically for inclusion in such
Registration Statement or Prospectus.  The Company shall be entitled to receive
indemnities from underwriters, selling brokers, dealer managers and similar
securities industry professionals participating in the distribution, to the
same extent as provided above with respect to information so furnished in
writing by such Persons specifically for inclusion in any Prospectus or
Registration Statement.  The obligation of the Investor to indemnify hereunder
shall be limited to the net amount of proceeds received by such Investor from
the sale of  Registrable Securities pursuant to such Registration Statement or
Prospectus.

                 (c)      Conduct of Indemnification Proceedings.  Any Person
entitled to indemnification hereunder will (i) give prompt notice to the
indemnifying party of any claim with respect to which it seeks indemnification
(provided that the failure to give prompt notice shall not impair any Person's
right to indemnification hereunder to the extent such failure has not
materially prejudiced the indemnifying party) and (ii) permit such indemnifying
party to assume the defense of such claim with counsel reasonably satisfactory
to the indemnified party; provided, however, that any Person entitled to
indemnification hereunder shall have the right to employ separate counsel and
to participate in the defense of such claim, but the fees and expenses of such
counsel shall be at the expense of such Person unless (a) the indemnifying
party has agreed to pay such fees or expenses, (b) the indemnifying party shall
have failed to assume the defense of such claim and employ counsel reasonably
satisfactory to such Person or (c) based upon written advice of counsel to such
Person, there shall be one or more defenses available to such Person that are
not available to the
<PAGE>   11
indemnifying party or there shall exist conflicts of interest pursuant to
applicable rules of professional conduct between such Person and the
indemnifying party (in which case, if the Person notifies the indemnifying
party in writing that such Person elects to employ separate counsel at the
expense of the indemnifying party, the indemnifying party shall not have the
right to assume the defense of such claim on behalf of such Person), in each of
which events the fees and expenses of such counsel shall be at the expense of
the indemnifying party.  The indemnifying party will not be subject to any
liability for any settlement made without its consent (but such consent will
not be unreasonably withheld), but if settled with its written consent, or if
there be a final judgment for the plaintiff in any such action or proceeding,
the indemnifying party shall indemnify and hold harmless the indemnified
parties from and against any loss or liability (to the extent stated above) by
reason of such settlement or judgment.  No indemnified party will be required
to consent to entry of any judgment or enter into any settlement which does not
include as an unconditional term thereof the giving by the claimant or
plaintiff to such indemnified party of a release from all liability in respect
to such claim or litigation.

                 (d)      Contribution.  If for any reason the indemnification
provided for in the preceding clauses (a) and (b) is unavailable to an
indemnified party or insufficient to hold it harmless as contemplated by the
preceding clauses (a) and (b), then the indemnifying party shall contribute to
the amount paid or payable by the indemnified party as a result of such Loss in
such proportion as is appropriate to reflect not only the relative benefits
received by the indemnified party and the indemnifying party, but also the
relative fault of the indemnified party and the indemnifying party, as well as
any other relevant equitable considerations.  The relative fault of the Company
and the Investor shall be determined by reference to, among other things,
whether the untrue or alleged untrue statement of a material fact or the
omission or alleged omission to state a material fact relates to information
supplied by such party, and the parties' relative intent, knowledge, access to
information, and opportunity to correct or prevent such statement or omission.
No Person guilty of fraudulent misrepresentation (within the meaning of Section
11(f) of the Securities Act) shall be entitled to contribution from any Person
who was not guilty of such fraudulent misrepresentations.

         8.      Rule 144.  The Company hereby agrees that it will timely file
the reports required to be filed by it under the Securities Act and the
Exchange Act and the rules and regulations adopted by the SEC thereunder (or,
if the Company is not required to file such reports, it will, upon the request
of the Investor, make publicly available other information so long as necessary
to permit sales pursuant to Rule 144 under the Securities Act), and it will
take such further action as the Investor may reasonably request, all to the
extent required from time to time to enable the Investor to sell Registrable
Securities without registration under the Securities Act within the limitation
of the exemptions provided by Rule 144.  Upon the request of the Investor, the
Company will deliver to the Investor a written statement as to whether it has
complied with such information and requirements.

         9.      Participation in Underwritten Registrations.  No Person may
participate in any Underwritten Registration hereunder unless such Person (i)
agrees to sell such Person's securities on the basis provided in any
underwriting arrangements approved by the Company and (ii) completes and
executes all questionnaires, powers of attorney, indemnities, underwriting
agreements and other documents reasonably required under the terms of such
underwriting arrangements.
<PAGE>   12
Nothing in this Section 8 shall be construed to create any additional rights
regarding the registration of Registrable Securities in any Person otherwise
than as set forth herein.

         10.     Miscellaneous.

                 (a)      Other Registration Rights.  Notwithstanding anything
in this Agreement to the contrary, nothing in this Agreement shall be construed
as limiting the ability of Morgan Stanley Asset Management Inc. and its clients
and affiliates, USAA Real Estate Company, ABKB/LaSalle Securities Limited
Partnership and its clients, and LaSalle Advisors Limited Partnership and its
clients (collectively, the "Majority Shareholders"), from exercising their
registration rights which were granted to them by the Company.

                 (b)      Remedies.  Each party hereto, in addition to being
entitled to exercise all rights provided herein or granted by law, including
recovery of damages, will be entitled to specific performance of its rights
under this Agreement to the extent available under applicable law.  Each party
hereto agrees that monetary damages would not be adequate compensation for any
loss incurred by reason of a breach by it of the provisions of this Agreement
and hereby agrees to waive the defense in any action for specific performance
that a remedy at law would be adequate.

                 (c)      Amendments and Waivers.  The provisions of this
Agreement, including the provisions of this sentence, may not be amended,
modified or supplemented, and waivers or consents to departures from the
provisions hereof may not be given without the written consent of the Company
and the Investor.

                 (d)      Notices. The notice provisions contained in Article
12 of the Contribution  Agreement shall be incorporated herein and shall be
governing under this Agreement.

                 (e)      Successors and Assigns.  This Agreement and the
rights granted hereunder may not be assigned by the Investor without the
written consent of the Company.  Notwithstanding  the foregoing, the Investor
may assign its rights under Section 2 or 3 hereof to (i) any of its employees,
officers or directors who, in the reasonable opinion of counsel to the Company,
are "accredited investors" within the meaning of Rule 501(a) promulgated under
the Securities Act or (ii) Permitted Transferees (under and defined in the
partnership agreement of the Operating Partnership); provided that no
transferee shall have any of the rights granted under this Agreement until such
transferee shall acknowledge its rights and obligations hereunder by a signed
written statement of each transferee's acceptance of such rights and
obligations.

                 (f)      Counterparts.  This Agreement may be executed in any
number of counterparts and by the parties hereto in separate counterparts, each
of which when so executed shall be deemed to be an original and all of which
taken together shall constitute one and the same agreement.

                 (g)      Headings.  The headings in this Agreement are for
convenience of reference only and shall not limit or otherwise affect the
meaning hereof.
<PAGE>   13
                 (h)      GOVERNING LAW.  THIS AGREEMENT, AND THE RIGHTS AND
OBLIGATIONS OF THE PARTIES HERETO, SHALL BE GOVERNED BY AND CONSTRUED AND
ENFORCED IN ACCORDANCE WITH THE INTERNAL SUBSTANTIVE LAWS OF THE STATE OF
TEXAS, WITHOUT REGARD TO ITS PRINCIPLES OF CONFLICTS OF LAWS.

                 (i)      Severability.  If any provision of this Agreement is
held to be illegal, invalid or unenforceable under any current or future law,
and if the rights or obligations of the parties under this Agreement would not
be materially and adversely affected thereby, such provision shall be fully
separable, and this Agreement shall be construed and enforced as if such
illegal, invalid or unenforceable provision had never comprised a part thereof,
and the remaining provisions of this Agreement shall remain in full force and
effect and shall not be affected by the illegal, invalid or unenforceable
provision or by its severance therefrom.  In lieu of such illegal, invalid or
unenforceable provision, there shall be added simultaneously as a part of this
Agreement, a legal, valid and enforceable provision as similar in terms to such
illegal, invalid or unenforceable provision as may be possible, and the parties
hereto request the court or any arbitrator to whom disputes relating to this
Agreement are submitted to reform the otherwise illegal, invalid or
unenforceable provision in accordance with this Section 10(i).

                 (j)      ARBITRATION.  ANY DISPUTE OR CLAIM IN LAW OR EQUITY
ARISING OUT OF OR RELATED TO THIS AGREEMENT (A "CLAIM") SHALL BE RESOLVED BY
NEUTRAL BINDING ARBITRATION IN ACCORDANCE WITH THE COMMERCIAL ARBITRATION RULES
OF THE AMERICAN ARBITRATION ASSOCIATION AND JUDGMENT ON THE AWARD RENDERED BY
THE ARBITRATION PANEL MAY BE ENTERED IN ANY COURT OR TRIBUNAL OF COMPETENT
JURISDICTION.  ANY ARBITRATION OCCURRING UNDER THIS SECTION 10(J) SHALL BE HELD
IN DALLAS, TEXAS.  ANY PARTY WHICH SHALL BE THE PREVAILING PARTY IN ANY
ARBITRATION CONDUCTED HEREUNDER (AS DETERMINED BY THE ARBITRATOR) SHALL BE
ENTITLED TO RECOVER FROM THE NON-PREVAILING PARTY REIMBURSEMENT OF ALL
REASONABLE COSTS OF SUCH ARBITRATION (INCLUDING REASONABLE ATTORNEYS' FEES).
EACH PARTY HERETO HEREBY WAIVES ITS RIGHT TO COMMENCE ANY ACTION IN CONNECTION
WITH ANY CLAIM IN ANY COURT (OTHER THAN AN ACTION FOR THE SOLE PURPOSE TO
ENFORCING THE OBLIGATION OF A PARTY HERETO TO SUBMIT TO BINDING ARBITRATION OR
THE ENFORCEMENT OF AN AWARD GRANTED BY ARBITRATION HEREUNDER) AND EXPRESSLY
AGREES TO BE BOUND BY THE DETERMINATION OF THE ARBITRATOR UNDER THIS SECTION
10(J).

                 (k)      Entire Agreement.  This Agreement is intended by the
parties as a final expression of their agreement and intended to be a complete
and exclusive statement of the agreement and understanding of the parties
hereto in respect of the subject matter contained herein.  This Agreement
supersedes all prior agreements and understandings between the parties with
respect to such subject matter.

         IN WITNESS WHEREOF, the parties hereto have executed this Registration
Rights Agreement as of the date first written above.

                                                                   EXHIBIT 99.7
                                        
                         REGISTRATION RIGHTS AGREEMENT

              This Registration Rights Agreement (the "Agreement") is made and
entered into as of October 3, 1997, by and among American Industrial Properties
REIT, a Texas real estate investment trust (the "Company"), and AG Industrial
Investors, L.P., a Delaware limited partnership (the "Investor").

       WHEREAS, the Company, AIP-SWAG Operating Partnership, L.P., a Delaware
limited partnership (the "Operating Partnership"), and Shidler West Investment
Corporation ("Shidler West"), acting on behalf of  the Investor and Shidler
West Acquisition Company, LLC, have entered into a Contribution and Exchange
Agreement, dated as of September 25, 1997 (the "Contribution Agreement"),
pursuant to which, among other things, the Operating Partnership agreed to
acquire the right to purchase certain real property from Shidler West;

       WHEREAS, pursuant to the Contribution Agreement, the Operating
Partnership has agreed to issue to the Investor  (i) 447,712.5 units of limited
partnership interest of the Operating Partnership (the "Units"), which will be
convertible into 447,712.5 shares (the "Converted Shares") of beneficial
interest, par value $.10 per share, of the Company (the "Common Shares"), and
(ii) a warrant to purchase up to an aggregate amount of 100,000 Common Shares
(the "Warrant Shares," and  together with the Converted Shares, the "Shares");
and

       WHEREAS, pursuant to the terms of the Contribution Agreement, the
Company and the Investor agreed that the Company would grant certain
registration rights to the Investor;

              NOW, THEREFORE, for valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the parties hereto agree as
follows:

       1.     Certain Definitions.

              As used in this Agreement, the following capitalized terms shall
have the following meanings:

              Closing Date: The closing date as defined in the Contribution
Agreement.

              Exchange Act: The Securities Exchange Act of 1934, as amended.

              Person: An individual, partnership,  corporation, limited
liability company, trust or unincorporated organization, or a government or
agency or political subdivision thereof.

              Prospectus: The prospectus included in any Registration
Statement, as amended or supplemented by any prospectus supplement with respect
to the terms of the offering of any portion of the Registrable Securities
covered by such Registration Statement and by all other amendments and
supplements to the prospectus, including post-effective amendments and all
material incorporated by reference in such prospectus.
<PAGE>   2
              Registrable Securities: (a) The Shares and (b) any securities
issued or issuable with respect to the Shares by way of stock dividend or stock
split or in connection with a combination of shares, recapitalization, merger,
consolidation or other reorganization or otherwise.  Any Registrable Security
will cease to be a Registrable Security when (i) a registration statement
covering such Registrable Security has been declared effective by the SEC and
the Registrable Security has been disposed of pursuant to such effective
registration statement; (ii) the Registrable Security has been sold pursuant to
Rule l44 or any other valid exemption from registration; or (iii) the
Registrable Security has been otherwise transferred, the Company has delivered
a new certificate or other evidence of ownership for it not bearing a legend
restricting further transfer, and it may be resold by the holder thereof
without subsequent registration under the Securities Act.

              Registration Statement: A Registration Statement of the Company
that covers any of the Registrable Securities pursuant to the provisions of
this Agreement, including the Prospectus included therein, all amendments and
supplements to such Registration Statement or Prospectus, including
post-effective amendments, all exhibits and all material incorporated by

              Rule 144:  Rule 144 under the Securities Act, as such Rule may be
amended from time to time, or any similar rule or regulation hereafter adopted
by the SEC.

              SEC: The Securities and Exchange Commission or any successor
entity.

              Securities Act: The Securities Act of 1933, as amended.

              Underwritten Registration or Underwritten Offering: A
registration under the Securities Act in which securities of the Company are
sold to an underwriter for reoffering to the public.

       2.     Demand Registration.

              (a)    Requests for Registration.  At any time after the second
anniversary  (the first anniversary with respect to the Warrant Shares) of the
Closing Date, the Investor may make a written request (the "Demand Notice") for
registration under the Securities Act (a "Demand Registration") of the number
of  Registrable Securities requested to be registered pursuant to the terms of
this Agreement. The Demand Notice will specify the number of shares of
Registrable Securities proposed to be sold and will also specify the intended
method of disposition thereof.  Following receipt of a Demand Notice from the
Investor, the Company promptly will file a Registration Statement on any
appropriate form that will cover the Registrable Securities that the Company
has been so requested to register by the Investor.

       The Company shall not be required to effect more than one Demand
Registration under this Section 2.  A registration requested pursuant to this
Section 2 will not be deemed to have been effected unless the Registration
Statement relating thereto has become effective under the Securities Act;
provided, however that if, after such Registration Statement has become
effective, the offering of the Registrable Securities pursuant to such
registration is interfered with by any stop order,
<PAGE>   3
injunction or other order or requirement of the SEC or other governmental
agency or court, such registration will be deemed not to have been effected.

       If the Investor requests that a Demand Registration be a "shelf"
registration pursuant to Rule 415 under the Securities Act, the Company shall
file the Demand Registration under Rule 415 and shall keep the Registration
Statement filed in respect thereof effective for a period that will terminate
on the earlier of (i) 180 days from the date on which the SEC declares such
Registration Statement effective and (ii) the date on which all Registrable
Securities covered by such Registration Statement have been sold pursuant to
such Registration Statement; provided that such 180 day period shall be tolled
during the period that the Investor is required to discontinue disposition of
Registrable Securities pursuant to the last paragraph of Section 4.

              (b)    Additional Shares.  The parties agree that any
Registration Statement may register shares that are not Registrable Securities,
but (i) are proposed to be sold by the Company or (ii) are Common Shares held
by other Persons, or to be issued to other Persons, and subject to registration
rights.

              (c)    Priority on Registration.  If any of the Registrable
Securities registered pursuant to a Demand Registration are to be sold in an
Underwritten Offering, and the managing underwriter or underwriters of such
offering advise the Company and the Investor in writing that in their opinion
the total number of shares or dollar amount of Registrable Securities proposed
to be sold in such offering is sufficiently large to materially and adversely
affect the success of such offering, the Company will include in such
registration the aggregate number or dollar amount of Registrable Securities
that in the opinion of such managing underwriter or underwriters can be sold
without any such material adverse effect; provided, however, that no
Registrable Securities, if any, may be excluded before all shares proposed to
be sold by other parties, including the Company, have been excluded.  If any
Registrable Securities are excluded, such registration shall not count as one
of the two Demand Registrations.

              (d)    Postponement of Registration.  The Company shall be
entitled to postpone, for a reasonable period of time not in excess of 90 days
during any 365-day period, the filing of a Registration Statement if the
Company determines, in the good faith exercise of its reasonable business
judgment, that such registration and offering could adversely affect or
interfere with bona fide financing plans of the Company or any of its
affiliates or would require disclosure of information, the premature disclosure
of which could adversely affect the Company or any transaction under
consideration by the Company.
<PAGE>   4
       3.     Piggyback Registration

              (a)    Right to Piggyback.  If at any time the Company proposes
to file a registration statement under the Securities Act with respect to an
offering of Common Shares (other than a registration statement (i) on Form S-4
or Form S-8 or any successor forms thereto or  to register for resale any
securities awarded pursuant to an unregistered offering to the Company's
employees or Trust Managers, or to employees of its subsidiaries, pursuant to
any employee benefit plan (as defined in Rule 405 under the Securities Act),
(ii) in connection with an exchange offer, or (iii) in connection with the
acquisition of assets by the Company, the Operating Partnership or any of their
affiliates), whether or not for its own account, then the Company shall give
written notice of such proposed filing to the Investor at least 30 days before
the anticipated filing date.  Such notice shall offer the Investor  the
opportunity to register such amount of Registrable Securities as the Investor
may request (a "Piggyback Registration").  Subject to Section 3(b) hereof, the
Company shall include in each such Piggyback Registration all Registrable
Securities with respect to which the Company has received a written request for
inclusion therein within 10 days after notice has been given to the Investor
(which  request shall specify the intended method of distribution).  The
Investor  shall be permitted to withdraw all or part of the Registrable
Securities from a Piggyback Registration at any time prior to the effective
date of such Piggyback Registration.  The Company shall not be required to
effect more than two Piggyback Registrations under this Section 3.

       (b)    Priority on Piggyback Registrations.  The Company shall cause the
managing underwriter of a proposed Underwritten Offering to include all such
Registrable Securities on the same terms and conditions as any other Common
Shares, if any, of the Company included therein.  Notwithstanding the
foregoing, if the managing underwriter of such Underwritten Offering delivers
an opinion to the Investor that the total number or dollar amount of securities
that the Investor, the Company and other Persons having rights to participate
in such registration, propose to include in such offering is such as to
materially and adversely affect the success of such offering, then the amount
of Common Shares to be offered (i) for the account of Investor and (ii) for the
account of all such other Persons (other than the Company) shall be reduced or
limited pro rata in proportion to the respective dollar amounts of  Common
Shares requested by such persons to be included in such offering.

       4.     Hold-Back Agreements.

              (a)    Restrictions on Public Sale by Holder of Registrable
Securities.  So long as the Investor holds Registrable Securities, the Investor
agrees, in connection with any sale of securities by the Company and in
connection with any Registration Statement filed pursuant to Section 2 or 3, if
requested by the Company or the managing underwriters in an Underwritten
Offering, not to effect any public sale or distribution of securities of the
Company, including a sale pursuant to Rule 144 (except as part of such
Underwritten Offering), during the 10-day period prior to, and during the
90-day period beginning on, the closing date of each offering made by the
Company or pursuant to such Registration Statement, to the extent timely
notified in writing by the Company or the managing underwriters; provided that
such restrictions shall not be more restrictive in duration or scope than
restrictions imposed on (i) any Person which has been granted registration
rights by the Company (other than the "Majority Shareholders"), (ii) any
officer or director of the
<PAGE>   5
Company or (iii) any 5% holder of Common Shares of the Company (other than the
"Majority Shareholders").

              (b)    Restrictions on Sale of Securities by the Company.  So
long as the Investor holds Registrable Securities, the Company agrees that,
without the written consent of the managing underwriter or underwriters in an
Underwritten Offering of Registrable Securities covered by a Registration
Statement filed pursuant to Section 2 or 3,  not to effect any public sale or
distribution of any securities similar to those being registered, or any
securities convertible into or exchangeable or exercisable for such securities
during the 10-day period prior to, and the 90-day period beginning on, the
closing date of each Underwritten Offering (except (w) as part of such
Underwritten Offering, (x)  pursuant to registrations on Form S-4 or Form S-8
or any successor form to such forms or  to register for resale any securities
awarded pursuant to an offering to the Company's employees or Trust Managers,
or to employees of its subsidiaries, pursuant to any employee benefit plan (as
defined in Rule 405 under the Securities Act), (y) in connection with an
exchange offer or (z) in connection with the acquisition of assets by the
Company, the Operating Partnership or any of their affiliates).

       5.     Registration Procedures.  In connection with the Company's
registration obligations pursuant to Section 2 or 3 hereof, the Company will
use its commercially reasonable efforts to effect such registration to permit
the sale of such Registrable Securities in accordance with the intended method
or methods of distribution thereof, and pursuant thereto the Company will use
commercially reasonable efforts to as expeditiously as possible:

              (a)    prepare and file with the SEC, as soon as practicable, a
Registration Statement relating to the applicable registration on any
appropriate form under the Securities Act that shall be available for the sale
of the Registrable Securities in accordance with the intended method or methods
of distribution thereof, and use its commercially reasonable efforts to cause
such Registration Statement to become effective; provided that before filing a
Registration Statement or Prospectus or any amendments or supplements thereto,
including documents incorporated by reference after the initial filing of the
Registration Statement, the Company will furnish the Investor and the
underwriters, if any, copies of all such documents proposed to be filed, which
documents will be subject to the review of the Investor and the underwriters,
if any; provided, further, that the Company shall not be required to deliver to
the Investor or the underwriters a copy of any such document that has not been
materially changed from a copy of such document that was previously delivered
to the Investor and the underwriters.  The Company will not file any
Registration Statement or amendment thereto or any Prospectus or any supplement
thereto (including such documents incorporated by reference) to which the
Investor or the underwriters, if any, shall reasonably object, in writing, on a
timely basis, unless, in the opinion of the Company, such filing is necessary
to comply with applicable law;

              (b)    prepare and file with the SEC such amendments and
post-effective amendments to the Registration Statement as may be necessary to

promptly, and (if requested by any such Person) confirm such advice in writing,
(l) when the Registration Statement, the Prospectus or any Prospectus
supplement or post-effective amendment has been filed, and, with respect to the
Registration Statement or any post-effective amendment thereto, when the same
has become effective, (2) of any request by the SEC for amendments or
supplements to the Registration Statement or the Prospectus or for additional
information (provided that the Company shall not be required to notify the
Investor of all "comment" letters received by the Company from the SEC or to
deliver copies of such comment letters or the Company's responses thereto to
the Investor unless such letters request information from or about the
Investor), (3) of the issuance by the SEC of any stop order suspending the
effectiveness of the Registration Statement or the initiation of any
proceedings for that purpose, (4) if at any time the representations and
warranties of the Company contemplated by Section 5(m)(1) below cease to be
true and correct, (5) of the receipt by the Company of any notification with
respect to the suspension of the qualification of the Registrable Securities
for sale in any jurisdiction or the initiation or threatening of any proceeding
for such purpose and (6) of the happening of any event which makes any
statement made in the Registration Statement, the Prospectus or any document
incorporated therein by reference untrue in any material respect or that
requires the making of any changes in the Registration Statement, the
Prospectus or any document incorporated therein by reference so that, in the
case of the Registration Statement, it will not contain any untrue statement of
a material fact or omit to state any material fact required to be stated
therein or necessary to make the statements therein not misleading, and that,
in the case of the Prospectus, it will not contain any untrue statement of a
material fact or omit to state any material fact necessary in order to make the
statements therein, in light of the circumstances under which they were made,
not misleading;

              (d)    obtain the withdrawal of any order suspending the
effectiveness of the Registration Statement;

              (e)    if requested by the managing underwriter or underwriters

the intended method of distribution of such securities and make all required
filings of such Prospectus supplement or post-effective amendment as soon as
practicable after the Company has received such request; provided, however,
that the Company shall not be required to take any actions under this Section
5(e) that are not in compliance with applicable law;

              (f)    furnish to the Investor and each managing underwriter, if
any, without charge, at least one signed copy of the Registration Statement and

<PAGE>   7
thereto as such Persons may reasonably request; the Company consents to the use
of the Prospectus (including each preliminary prospectus) or any amendment or
supplement thereto by the Investor and the underwriters, if any, in connection
with the offering and sale of the Registrable Securities covered by the
Prospectus or any amendment or supplement thereto;

              (h)    prior to any public offering of Registrable Securities,
register or qualify or cooperate with the Investor, the underwriters, if any,
and their respective counsel in connection with the registration or
qualification of such Registrable Securities for offer and sale under the
securities or blue sky laws of such jurisdictions within the United States as
the Investor or any underwriter reasonably requests in writing and do any and
all other acts or things necessary or advisable to enable the disposition in
such jurisdictions of the Registrable Securities covered by the Registration
Statement; provided, however, that the Company will not be required to (A)
qualify generally to do business in any jurisdiction where it not then so
qualified or (B) take any action that would subject the Company to general
service of process or to taxation in any such jurisdiction where it is not then
so subject;

              (i)    cooperate with the Investor and the managing underwriters,
if any, to facilitate the timely preparation and delivery of certificates

legends; and enable such Registrable Securities to be in such denominations and
registered in such names as the managing underwriters may request at least two
business days prior to any sale of Registrable Securities to the underwriters;

              (j)    cause the Registrable Securities covered by the applicable
Registration Statement to be registered with or approved by such other
governmental agencies or authorities as may be necessary to enable the Investor
or the underwriters, if any, to consummate the disposition of such Registrable
Securities;

              (k)    upon the occurrence of any event contemplated by Section
5(c)(6) above, prepare a supplement or post-effective amendment to the
Registration Statement or the related Prospectus or any document incorporated
therein by reference or file any other required document so that, as thereafter
delivered to the purchasers of the Registrable Securities, the Prospectus will
not contain an untrue statement of a material fact or omit to state any
material fact required to be stated therein or necessary to make the statements
therein, in light of the circumstances under which they  were made, not
misleading;

              (l)    cause all Registrable Securities covered by the
Registration Statement to be listed on each securities exchange on which
similar securities issued by the Company are then listed;

              (m)    enter into such agreements (including an underwriting
agreement in form, scope and substance as is customary in underwritten
offerings) and take all such other actions reasonably requested by the Investor
or the managing underwriter or underwriters, if any, in order to expedite or
facilitate the disposition of such Registrable Securities and in connection
therewith, whether or not an underwriting agreement is entered into and whether
or not the registration is an Underwritten Registration, (1) make such
representations and warranties to the Investor, and the underwriters, if any,
in form, substance and scope as are customarily made by issuers to underwriters
<PAGE>   8
in primary underwritten offerings; (2) obtain opinions of counsel to the
Company and updates thereof (which counsel and opinions (in form, scope and
substance) shall be reasonably satisfactory to the Investor and the managing
underwriters, if any, covering the matters customarily covered in opinions
requested in Underwritten Offerings and such other matters as may be reasonably
requested by the Investor and the underwriters, if any; (3) obtain "cold
comfort" letters and updates thereof from the Company's independent certified
public accountants addressed to the Investor and the underwriters, if any, such
letters to be in customary form and covering matters of the type customarily
covered in "cold comfort" letters by underwriters in connection with primary
Underwritten Offerings (unless such accountants shall be prohibited from so
addressing such letters by applicable standards of the accounting profession);
(4) if an underwriting agreement is entered into, the same shall contain the
indemnification provisions and procedures substantially to the effect set forth
in Section 7 hereof with respect to all parties to be indemnified pursuant to
said Section; and (5) deliver such documents and certificates as may be
reasonably requested by the Investor and the managing underwriters, if any, to
evidence compliance with clause (1) above and with any customary conditions
contained in the underwriting agreement or other agreement entered into by the
Company.  The above shall be done at each closing under such underwriting or
similar agreement or as and to the extent required thereunder;

              (n)    make available for inspection by a representative of the
Investor, any underwriter participating in any disposition pursuant to such
registration, and any attorney or accountant retained by the Investor or any
underwriter, at the offices where normally kept, during reasonable business
hours, all financial and other records, pertinent corporate documents and
properties of the Company and cause the Company's officers, trust managers and
employees to supply all information reasonably requested by any such
representative, underwriter, attorney or accountant in connection with such
registration; provided that any records, information or documents that the
Company designates in writing as confidential shall be kept confidential by
such Persons unless disclosure of such records, information or documents is
required by court or administrative order.  Without limiting the foregoing, no
such information shall be used by such Person as the basis for any market
transactions in securities of the Company or its subsidiaries in violation of
law;

              (o)    otherwise comply with all applicable rules and regulations
of the SEC, and make available to its security holders, as soon as reasonably
practicable, an earnings statement covering a period of 12 months, beginning
within three months after the effective date of the Registration Statement,
which earnings statement shall satisfy the provisions of Section 11(a) of the
Securities Act; and

              (p)    cooperate with the Investor and each underwriter
participating in the disposition of such Registrable Securities and their
respective counsel in connection with any filings required to be made with the
National Association of Securities Dealers, Inc. (the "NASD").

       The Company may require the Investor to furnish to the Company such
information regarding the distribution of Registrable Securities as the Company
may from time to time reasonably request in writing, and the Company may
exclude from such registration the Registrable Securities of the Investor if it
unreasonably fails to furnish such information within a reasonable time after
receiving such request.
<PAGE>   9
       The Investor agrees by acquisition of the Registrable Securities that,
upon receipt of any notice from the Company of the happening of any event of
the kind described in Section 5(c) (2), 5(c)(3), 5(c)(5) and 5(c)(6) hereof,
the Investor will forthwith discontinue disposition of Registrable Securities
until the Investor's receipt of the copies of the supplemented or amended
Prospectus contemplated by Section 5(k) hereof, or until it is advised in
writing by the Company that the use of the Prospectus may be resumed, and has
received copies of any additional or supplemental filings which are
incorporated by reference in the Prospectus, and, if so directed by the
Company, the Investor will deliver to the Company (at the Company's expense),
all copies, other than permanent file copies then in the Investor's possession,
of the Prospectus covering such Registrable Securities current at the time of
receipt of such notice.

              6.     Registration Expenses.  All reasonable expenses incident
to the Company's performance of or compliance with this Agreement, including,
without limitation, all registration and filing fees; fees with respect to
filings required to be made with the NASD; fees and expenses of compliance with
securities or blue sky laws (including fees and disbursements of counsel for
the underwriters or the Investor in connection with blue sky qualifications of
the Registrable Securities pursuant to Section 5(h)); printing expenses;
messenger, telephone and delivery expenses; fees and disbursements of counsel
for the Company; reasonable fees and disbursements of counsel for the Investor
up to $5,000 ; and fees and expenses for independent certified public

letters or costs associated with the delivery by independent certified public
accountants of a comfort letter or comfort letters requested pursuant to
Section 5(m)(3) hereof); securities acts liability insurance, if the Company so
desires; all internal expenses of the Company (including, without limitation,
all salaries and expenses of its officers and employees performing legal or
accounting duties); the expense of any annual audit; the fees and expenses
incurred in connection with the listing of the securities to be registered on
each securities exchange on which similar securities issued by the Company are
then listed; and the fees and expenses of any Person, including special
experts, retained by the Company will be borne by the Company regardless of
whether the Registration Statement becomes effective. The Company shall not
have any obligation to pay (i) any underwriting fees, discounts or commissions
attributable to the sale of Registrable Securities, (ii) any legal fees and
expenses of counsel to the Investor or underwriters, except as expressly
provided herein, or (iii) any fees and expenses of any "qualified independent
underwriter" or other independent appraiser participating in an offering
pursuant to Section 3 of Schedule E to the By-laws of the NASD.

       7.     Indemnification: Contribution.

              (a)    Indemnification by Company.  The Company agrees to
indemnify and hold harmless the Investor and its partners, officers, directors,
employees and agents, and each Person who controls any such Persons (within the
meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act)
(collectively, the "Investor") against all losses claims, damages, liabilities
and expenses (collectively, "Losses") arising out of or based upon any untrue
or alleged untrue statement of a material fact contained in any Registration
Statement, Prospectus or preliminary prospectus or any omission or alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, except insofar as the
same are caused by or contained in any information furnished in writing to the
Company by the Investor
<PAGE>   10
expressly for use therein; provided, however, that the Company shall not be
liable to the Investor to the extent that any Losses arise out of or are based
upon an untrue statement or alleged untrue statement or omission or alleged
omission make in any preliminary prospectus if (i) the Investor failed to send
or deliver a copy of the Prospectus with or prior to the delivery of written
confirmation of the sale by the Investor of a Registrable Security to the
Person asserting the claim from which such Losses arise and (ii) the Prospectus
would have corrected in all material respects such untrue statement or alleged
untrue statement or such omission or alleged omission; provided, further, that
the Company shall not be liable in any such case to the extent that any such
Losses arise out or are based upon an untrue statement or alleged untrue
statement or omission or alleged omission in the Prospectus, if (x) such untrue
statement or alleged untrue statement, omission or alleged omission is
corrected in all material respects in an amendment or supplement in the
Prospectus and (y) having previously been furnished by or on behalf of the
Company with copies of the Prospectus as so amended or supplemented, the
Investor thereafter fails to deliver such Prospectus as so amended or
supplemented, prior to or concurrently with the sale of a Registrable Security
to the Person asserting the claim for which such Losses arise.

              (b)    Indemnification By Holder of Registrable Securities. The
Investor agrees to indemnify and hold harmless the Company and its partners,
trust managers, officers, employees and agents, and each Person who controls
any such Persons (within the meaning of Section 15 of the Securities Act or
Section 20 of the Exchange Act) (collectively, the "Company") against all
Losses arising out of or based upon  any untrue statement of a material fact
contained in any Registration Statement, Prospectus or preliminary prospectus
or any omission or alleged omission to state therein a material fact required
to be stated therein or necessary to make the statements therein not
misleading, to the extent, but only to the extent, that such untrue statement
or omission is contained in any information or affidavit so furnished in
writing by the Investor to the Company specifically for inclusion in such
Registration Statement or Prospectus.  The Company shall be entitled to receive
indemnities from underwriters, selling brokers, dealer managers and similar
securities industry professionals participating in the distribution, to the
same extent as provided above with respect to information so furnished in
writing by such Persons specifically for inclusion in any Prospectus or
Registration Statement.  The obligation of the Investor to indemnify hereunder
shall be limited to the net amount of proceeds received by such Investor from
the sale of  Registrable Securities pursuant to such Registration Statement or
Prospectus.

              (c)    Conduct of Indemnification Proceedings.  Any Person
entitled to indemnification hereunder will (i) give prompt notice to the
indemnifying party of any claim with respect to which it seeks indemnification
(provided that the failure to give prompt notice shall not impair any Person's
right to indemnification hereunder to the extent such failure has not
materially prejudiced the indemnifying party) and (ii) permit such indemnifying
party to assume the defense of such claim with counsel reasonably satisfactory
to the indemnified party; provided, however, that any Person entitled to
indemnification hereunder shall have the right to employ separate counsel and
to participate in the defense of such claim, but the fees and expenses of such
counsel shall be at the expense of such Person unless (a) the indemnifying
party has agreed to pay such fees or expenses, (b) the indemnifying party shall
have failed to assume the defense of such claim and employ counsel reasonably
satisfactory to such Person or (c) based upon written advice of counsel to such
Person, there shall be one or more defenses available to such Person that are
not available to the
<PAGE>   11
indemnifying party or there shall exist conflicts of interest pursuant to
applicable rules of professional conduct between such Person and the
indemnifying party (in which case, if the Person notifies the indemnifying
party in writing that such Person elects to employ separate counsel at the
expense of the indemnifying party, the indemnifying party shall not have the
right to assume the defense of such claim on behalf of such Person), in each of
which events the fees and expenses of such counsel shall be at the expense of
the indemnifying party.  The indemnifying party will not be subject to any
liability for any settlement made without its consent (but such consent will
not be unreasonably withheld), but if settled with its written consent, or if
there be a final judgment for the plaintiff in any such action or proceeding,
the indemnifying party shall indemnify and hold harmless the indemnified
parties from and against any loss or liability (to the extent stated above) by
reason of such settlement or judgment.  No indemnified party will be required
to consent to entry of any judgment or enter into any settlement which does not
include as an unconditional term thereof the giving by the claimant or
plaintiff to such indemnified party of a release from all liability in respect
to such claim or litigation.

              (d)    Contribution.  If for any reason the indemnification
provided for in the preceding clauses (a) and (b) is unavailable to an
indemnified party or insufficient to hold it harmless as contemplated by the
preceding clauses (a) and (b), then the indemnifying party shall contribute to
the amount paid or payable by the indemnified party as a result of such Loss in
such proportion as is appropriate to reflect not only the relative benefits
received by the indemnified party and the indemnifying party, but also the
relative fault of the indemnified party and the indemnifying party, as well as
any other relevant equitable considerations.  The relative fault of the Company
and the Investor shall be determined by reference to, among other things,
whether the untrue or alleged untrue statement of a material fact or the
omission or alleged omission to state a material fact relates to information
supplied by such party, and the parties' relative intent, knowledge, access to
information, and opportunity to correct or prevent such statement or omission.
No Person guilty of fraudulent misrepresentation (within the meaning of Section
11(f) of the Securities Act) shall be entitled to contribution from any Person
who was not guilty of such fraudulent misrepresentations.

       8.     Rule 144.  The Company hereby agrees that it will timely file the
reports required to be filed by it under the Securities Act and the Exchange
Act and the rules and regulations adopted by the SEC thereunder (or, if the
Company is not required to file such reports, it will, upon the request of the
Investor, make publicly available other information so long as necessary to
permit sales pursuant to Rule 144 under the Securities Act), and it will take
such further action as the Investor may reasonably request, all to the extent
required from time to time to enable the Investor to sell Registrable
Securities without registration under the Securities Act within the limitation
of the exemptions provided by Rule 144.  Upon the request of the Investor, the
Company will deliver to the Investor a written statement as to whether it has
complied with such information and requirements.

       9.     Participation in Underwritten Registrations.  No Person may
participate in any Underwritten Registration hereunder unless such Person (i)
agrees to sell such Person's securities on the basis provided in any
underwriting arrangements approved by the Company and (ii) completes and
executes all questionnaires, powers of attorney, indemnities, underwriting
agreements and other documents reasonably required under the terms of such
underwriting arrangements.
<PAGE>   12
Nothing in this Section 8 shall be construed to create any additional rights
regarding the registration of Registrable Securities in any Person otherwise
than as set forth herein.

       10.    Miscellaneous.

              (a)    Other Registration Rights.  Notwithstanding anything in
this Agreement to the contrary, nothing in this Agreement shall be construed as
limiting the ability of Morgan Stanley Asset Management Inc. and its clients
and affiliates, USAA Real Estate Company, ABKB/LaSalle Securities Limited
Partnership and its clients, and LaSalle Advisors Limited Partnership and its
clients (collectively, the "Majority Shareholders"), from exercising their
registration rights which were granted to them by the Company.

              (b)    Remedies.  Each party hereto, in addition to being
entitled to exercise all rights provided herein or granted by law, including
recovery of damages, will be entitled to specific performance of its rights
under this Agreement to the extent available under applicable law.  Each party
hereto agrees that monetary damages would not be adequate compensation for any
loss incurred by reason of a breach by it of the provisions of this Agreement
and hereby agrees to waive the defense in any action for specific performance
that a remedy at law would be adequate.

              (c)    Amendments and Waivers.  The provisions of this Agreement,
including the provisions of this sentence, may not be amended, modified or
supplemented, and waivers or consents to departures from the provisions hereof
may not be given without the written consent of the Company and the Investor.

              (d)    Notices. The notice provisions contained in Article 12 of
the Contribution  Agreement shall be incorporated herein and shall be governing
under this Agreement.

              (e)    Successors and Assigns.  This Agreement and the rights
granted hereunder may not be assigned by the Investor without the written
consent of the Company.  Notwithstanding  the foregoing, the Investor may
assign its rights under Section 2 or 3 hereof to (i) any of its employees,
officers or directors who, in the reasonable opinion of counsel to the Company,
are "accredited investors" within the meaning of Rule 501(a) promulgated under
the Securities Act or (ii) Permitted Transferees (under and defined in the
partnership agreement of the Operating Partnership); provided that no
transferee shall have any of the rights granted under this Agreement until such
transferee shall acknowledge its rights and obligations hereunder by a signed
written statement of each transferee's acceptance of such rights and
obligations.

              (f)    Counterparts.  This Agreement may be executed in any
number of counterparts and by the parties hereto in separate counterparts, each
of which when so executed shall be deemed to be an original and all of which
taken together shall constitute one and the same agreement.

              (g)    Headings.  The headings in this Agreement are for
convenience of reference only and shall not limit or otherwise affect the
meaning hereof.
<PAGE>   13
              (h)    GOVERNING LAW.  THIS AGREEMENT, AND THE RIGHTS AND
OBLIGATIONS OF THE PARTIES HERETO, SHALL BE GOVERNED BY AND CONSTRUED AND
ENFORCED IN ACCORDANCE WITH THE INTERNAL SUBSTANTIVE LAWS OF THE STATE OF
TEXAS, WITHOUT REGARD TO ITS PRINCIPLES OF CONFLICTS OF LAWS.

              (i)    Severability.  If any provision of this Agreement is held
to be illegal, invalid or unenforceable under any current or future law, and if
the rights or obligations of the parties under this Agreement would not be
materially and adversely affected thereby, such provision shall be fully
separable, and this Agreement shall be construed and enforced as if such
illegal, invalid or unenforceable provision had never comprised a part thereof,
and the remaining provisions of this Agreement shall remain in full force and
effect and shall not be affected by the illegal, invalid or unenforceable
provision or by its severance therefrom.  In lieu of such illegal, invalid or
unenforceable provision, there shall be added simultaneously as a part of this
Agreement, a legal, valid and enforceable provision as similar in terms to such
illegal, invalid or unenforceable provision as may be possible, and the parties
hereto request the court or any arbitrator to whom disputes relating to this
Agreement are submitted to reform the otherwise illegal, invalid or
unenforceable provision in accordance with this Section 10(i).

              (j)    ARBITRATION.  ANY DISPUTE OR CLAIM IN LAW OR EQUITY
ARISING OUT OF OR RELATED TO THIS AGREEMENT (A "CLAIM") SHALL BE RESOLVED BY
NEUTRAL BINDING ARBITRATION IN ACCORDANCE WITH THE COMMERCIAL ARBITRATION RULES
OF THE AMERICAN ARBITRATION ASSOCIATION AND JUDGMENT ON THE AWARD RENDERED BY
THE ARBITRATION PANEL MAY BE ENTERED IN ANY COURT OR TRIBUNAL OF COMPETENT
JURISDICTION.  ANY ARBITRATION OCCURRING UNDER THIS SECTION 10(J) SHALL BE HELD
IN DALLAS, TEXAS.  ANY PARTY WHICH SHALL BE THE PREVAILING PARTY IN ANY
ARBITRATION CONDUCTED HEREUNDER (AS DETERMINED BY THE ARBITRATOR) SHALL BE
ENTITLED TO RECOVER FROM THE NON-PREVAILING PARTY REIMBURSEMENT OF ALL
REASONABLE COSTS OF SUCH ARBITRATION (INCLUDING REASONABLE ATTORNEYS' FEES).
EACH PARTY HERETO HEREBY WAIVES ITS RIGHT TO COMMENCE ANY ACTION IN CONNECTION
WITH ANY CLAIM IN ANY COURT (OTHER THAN AN ACTION FOR THE SOLE PURPOSE TO
ENFORCING THE OBLIGATION OF A PARTY HERETO TO SUBMIT TO BINDING ARBITRATION OR
THE ENFORCEMENT OF AN AWARD GRANTED BY ARBITRATION HEREUNDER) AND EXPRESSLY
AGREES TO BE BOUND BY THE DETERMINATION OF THE ARBITRATOR UNDER THIS SECTION
10(J).

              (k)    Entire Agreement.  This Agreement is intended by the
parties as a final expression of their agreement and intended to be a complete
and exclusive statement of the agreement and understanding of the parties
hereto in respect of the subject matter contained herein.  This Agreement
supersedes all prior agreements and understandings between the parties with
respect to such subject matter.
<PAGE>   14
       IN WITNESS WHEREOF, the parties hereto have executed this Registration
Rights Agreement as of the date first written above.

                       ARTICLE 2.  THE CREDIT FACILITIES

Expiration Date (or earlier termination of the Commitment Period hereunder),
subject to the terms and conditions hereinafter set forth, the Lender agrees to
make available to the Borrower on a joint and several basis, subject to Article
4 and Sections 2.02, 5.12, 5.14 and 7.04 hereof, one or more Loans in the
aggregate principal amount of up to the amount of the Available Commitment, to
be made to the Borrower upon the request of an Authorized Person in multiple
advances, each on a Borrowing Date.  All of the Loans shall be
cross-collateralized and cross-defaulted with full recourse to the Borrower.

         Section 2.02.  The Loans; Procedure for Borrowing.  (a)  Subject to
the terms and conditions hereof, the Lender agrees to make Loans to the
Borrower from the Lender's Office, from time to time during the Commitment
Period as provided in this Agreement in an aggregate principal amount at any
one time outstanding which will not exceed the Available Commitment.  The Loans
shall mature on the Expiration Date and bear interest for the period from the
Borrowing Date thereof to the date of payment in full thereof on the unpaid
principal amount thereof from time to time outstanding at the applicable
interest rates per annum determined and





                                       15
<PAGE>   21
payable as specified in Section 2.03 hereof.  The Loans shall be administered
by the Lender; provided, however, that the Lender may elect, at its expense, to
have the Loans administered and serviced by a third party.

         (b)(i)  Each Loan shall be made upon notice, given by an Authorized
Person of the Borrower to the Lender not later than 11:00 a.m. (New York City
time) on the third (3rd)Business Day prior to the requested Borrowing Date (a
"Notice of Borrowing").  Such notice shall be made by telecopy or telephone,
confirmed immediately in writing, by delivery of a Notice of Borrowing, in the
form of Exhibit K hereto, specifying therein (A) the requested Borrowing Date,
(B) the aggregate amount of the Loans therein requested to be made, which
amount shall not be greater than the Available Commitment or less than $100,000
or an integral multiple of $100,000 in excess thereof.  The Notice of Borrowing
shall be irrevocable and shall bind the Borrower to borrow in accordance with
such notice.  Upon fulfillment of the applicable conditions set forth herein,
the Lender will make such Loan available to the Borrower by disbursing such
proceeds as an Authorized Person of the Borrower may instruct the Lender in
advance in writing.

         (ii)  The obligations of the Borrower to pay the principal of and
interest on the Loans shall be evidenced by the Note in favor of the Lender
duly executed and delivered by the Borrower on a joint and several basis in the
form of Exhibit L hereto.  The Note shall (A) be payable to the order of the
Lender, (B) be in a stated principal amount equal to the Commitment and be
payable in the principal amount of the Loans evidenced thereby, (C) be stated
to mature (and each Loan shall be repayable) in full on the Expiration Date,
and (D) be entitled to the benefits of this Agreement.  At the time of each
Loan, and upon each prepayment of principal of each Loan, the Lender shall, and
is hereby authorized to, make a notation on the schedule annexed to and
constituting a part of the Note, and any such notation shall be conclusive and
binding for all purposes absent manifest error; provided, however, that the
failure by the Lender to make any such notation shall not affect the
obligations of the Borrower under the Note or this Agreement.  Although the
Note shall be dated the Closing Date, interest in respect thereof shall be
payable only for the periods during which the Loans evidenced thereby to the
Borrower are outstanding and although the stated amount of the Note shall be
equal to the Commitment, the Note shall be enforceable, with respect to the
obligations of the Borrower to pay the principal amount thereof, only to the
extent of the unpaid principal amount of the Loans to it at the time evidenced
thereby.

         Section 2.03.  Rate of Interest; Calculation of Interest.  (a)  Each
Loan shall bear interest on the unpaid principal amount thereof from the
Borrowing Date until such principal amount is paid in full at a rate or rates
per annum determined in accordance with this Section 2.03.  The Borrower shall
pay interest on the unpaid amount of each Loan at the rate per annum equal to
the sum of (i) LIBOR in effect from time to time applicable to each Interest
Period for such Loan, plus (ii) the Applicable Margin, payable in arrears on
each Interest Payment Date, commencing with the first of such dates to occur
after the Borrowing Date and ending on the date the principal amount of such
Loan shall be paid or prepaid, to the extent of the interest accrued on the
principal amount of such Loan so paid or prepaid.





                                       16
<PAGE>   22
         (b)  Each Conversion Loan shall bear interest on the unpaid principal
amount thereof from the Borrowing Date until such principal amount is paid in
full at a rate or rates per annum to be determined by the Lender based on the
then current yield on a ten (10) year Treasury note plus a margin determined by
Lender, payable in arrears on the last Business Day of each month, commencing
with the first of such dates to occur after the Conversion Date of such
Conversion Loan and ending on the date the principal amount of such Conversion
Loan shall be paid or prepaid.

         (c)  From and after the occurrence of any Event of Default under
Section 8.01 hereof, and for so long as such Event of Default shall continue
(after as well as before judgment), the unpaid principal amount of each Loan
and any other amount then due and payable but not yet paid hereunder shall bear
interest at a rate per annum equal to the then interest rate of such
outstanding Loan determined in accordance with clause (a) above plus three
hundred (300) basis points per annum, payable on demand.  Overdue interest
shall be compounded and bear interest, to the extent permitted by law, on each
date for payment of interest on the Loans hereunder.  The Borrower shall pay a
late charge of five percent (5%) of each monthly payment not paid within ten
(10) days after the date upon which such payment was due (which amount the
Borrower and the Lender agree is a fair and reasonable estimate of the Lender's
damages in light of all of the facts and circumstances as of the date of this
Agreement).  Such late charge shall be due and payable by the Borrower
concurrently with the late payment for which such charge is assessed hereunder.

         (d) Interest shall be calculated on a basis of a 360-day year for the
actual number of days elapsed during the Interest Period on the balance
outstanding during such Interest Period.  To the extent that interest is
required to be calculated at the Base Rate plus the Applicable Margin pursuant
to Section 2.11 hereof, any change in the interest rate on the Loans shall
become effective as of the opening of business on the day on which such change
in the Base Rate becomes effective.  The Lender shall, as soon as practicable,
notify the Borrower of the effective date and the amount of each such change in
the Base Rate; provided, however, that any failure by the Lender to give the
Borrower any such notice shall not affect the application of such change in the
Base Rate.  Each determination of an interest rate by the Lender pursuant to
any provision of this Agreement shall be, absent manifest error, deemed to be
correct.

         (e)  Anything herein to the contrary notwithstanding, the obligations
of the Borrower under this Agreement and the Note shall be subject to the
limitation that payments of interest shall not be required to the extent that
receipt thereof would be contrary to provisions of law applicable to the Lender
limiting rates of interest which may be charged or collected by the Lender.  If
the Borrower pays the Lender interest in excess of the maximum amount permitted
by applicable law, such excess shall be applied in reduction of the principal
balance of the Note, and any remaining excess shall be refunded to the
Borrower.

         Section 2.04.  Indemnity and Funding Losses.  The Borrower hereby
agrees to indemnify the Lender and to reimburse and hold the Lender harmless
from any Breakage Fees, loss, liability, cost or actual out-of-pocket expense
(including, without limitation, reasonable attorney's fees and expenses for the
Lender incurred in connection with any action or proceeding between





                                       17
<PAGE>   23
or among the Borrower and any Lender or between the Lender and any third party
or otherwise) that the Lender may sustain or incur as a consequence of (a) a
default by the Borrower in the payment of principal of, or interest on, any
Loan, (b) a default by the Borrower in borrowing (or in fulfilling on or before
the requested Borrowing Date the applicable conditions set forth in Article 4
hereof with respect to such borrowing), (c) a default by the Borrower in making
any prepayment after notice thereof has been given in accordance with Section
2.05 or 2.06 hereof, or (d) the Borrower making any payment of principal with
respect to any Loan on a day other than the last day of the Interest Period
applicable thereto.  The Lender shall deliver to the Borrower a certificate as
to the amount of such loss, liability, cost or expense, which certificate shall
be conclusive in absence of manifest error.  This covenant shall survive
payment of the Loans and termination of this Agreement as to claims arising
prior to the indefeasible payment in full of the Loans.

         Section 2.05.  Mandatory Prepayments.  (a)         Excess Of
Commitment.  If at any time the aggregate unpaid principal amount of the Loans
outstanding exceeds the Commitment, the Borrower shall immediately repay such
Loans, without premium or penalty, in a principal amount at least equal to such
excess and in a minimum amount equal to $10,000 or any larger whole multiple of
$10,000, together with accrued interest on the amount prepaid to the date of
repayment.

         (b)     Loan-To-Value Ratios.  If at any time the loan-to-value ratios
of the Collateral Properties do not comply with the provisions of Section 7.03
hereof; the Borrower shall promptly, but in no event later than the next
Interest Payment Date, at their option, (i) prepay a portion of the applicable
Loans without attendant breakage costs, or (ii) grant the Lender a first and
only mortgage interest, in form and substance satisfactory to the Lender, in
certain of its existing properties which are currently unencumbered and are
otherwise satisfactory to the Lender, in either case in an amount sufficient to
bring the loan-to-value ratios of the Collateral Properties back into
compliance with the provisions of Section 7.03 hereof.

         (c)     Asset Sales.  Subject to Section 6.05 hereof, the Borrower
shall apply all net proceeds of any Collateral sales as a mandatory prepayment
of the Loan without penalty or premium.  All such amounts designated for
mandatory prepayment, as aforesaid, shall be applied to the respective
scheduled principal payments outstanding, each in the inverse order of their
maturities.

         Section 2.06.  Optional Prepayments .  (a)  The Borrower may, upon at
least two (2) Business Days prior notice to the Lender, voluntarily prepay any
Loan in whole at any time or in part from time to time, with accrued interest
to the date of such prepayment on the amount prepaid but, subject to Section
2.04(d) hereof, without other premiums or penalties, in an amount not less than
$100,000 or an integral multiple of $100,000 in excess thereof.  Each such
notice shall be made by an Authorized Person of the Borrower by telecopy or
telephone, confirmed immediately in writing, by delivery of a Notice of
Optional Prepayment, substantially in the form of Exhibit M hereto, specifying
therein (i) the proposed date of such prepayment, and (ii) the aggregate amount
of the particular Loan(s) therein proposed to be prepaid.  Each Notice of
Optional Prepayment shall be irrevocable and shall bind the Borrower to make
such prepayment in accordance with such notice.

<PAGE>   24

made by the Borrower under this Agreement shall be made by wire transfer to the
Lender, in Dollars and in immediately available funds, at such place or places
as the Lender may from time to time designate by written notice to the
Borrower.  All payments to be made hereunder by the Borrower shall be made
without setoff, counterclaim or defense.  If any payment hereunder becomes due
and payable on a day other than a Business Day, the due date of such payment
shall be extended to the next succeeding Business Day and, with respect to
payments of principal, interest thereon shall be payable at the applicable rate
during such extension; provided, however, that no such payments of each Loan
shall extend beyond the Expiration Date.

         Section 2.08.  Use of Loan Proceeds. The Borrower shall use the
proceeds of the Loans solely to finance (i) the Acquisition by the Borrower of

acquisition complies with the provisions of Section 7.04 and Article 4 hereof
and the other covenants contained herein, (ii) the Transaction Costs, and (iii)
the Modifications.

         Section 2.09.  Fees.  (A)  A non-refundable, non-creditable funding

advance on the Borrowing Date.

         (B)     A non-refundable  expense reimbursement fee payable to the
Lender by the Borrower on the Closing Date and on each Borrowing Date
thereafter.   Such expense reimbursement fee shall include any fees and
expenses incurred or paid by Lender in connection with the processing,
underwriting or closing of a Loan, including, without limitation, property
inspection fees, appraisal fees, attorney fees, travel expenses of Lender's
personnel or Lender's attorneys, and other out-of-pocket expenses incurred by
Lender.  The $15,000 deposit previously paid to the Lender by the Borrower for
the Lender's out-of-pocket expenses, shall be credited against the expense
reimbursement fee on the Closing Date.

         (C)  A non-refundable, non-creditable facility fee of one percent (1%)

         Section 2.10.  Increased Costs.  If any Regulatory Change: (a)
subjects the Lender to any tax of any kind whatsoever with respect to this
Agreement, the Note or any Loan or changes the basis of taxation of payments to
the Lender of principal, interest, commitment fees, or any other amount payable
hereunder in any of the foregoing (except for changes in the rate of tax on the
overall net income of the Lender); (b) imposes, modifies or holds applicable to
the Lender (or any corporation controlling the Lender) any reserve or capital
adequacy requirements or liquidity ratios or requires the Lender or any
corporation controlling the Lender) to make special deposits against or in
respect of assets or liabilities of, deposits with or for the account of, or
credit extended by, the Lender; or (c) imposes on the Lender any other
condition affecting this Agreement, the Note or the Loans; and the result of
any of the foregoing is (i) to increase the cost to the Lender of making or
maintaining Loans or to reduce any amount received or receivable by the Lender
hereunder, (ii) to require the Lender (or any corporation controlling the
Lender) to





                                       19
<PAGE>   25
make any payment to any fiscal, monetary, regulatory or other authority
calculated on or by reference to any amount received or receivable by the
Lender under this Agreement or the Note, or (iii) to reduce the rate of return
on the Lender's capital as a consequence of its obligations hereunder to a
level below that which the Lender could have achieved but for such adoption,
change or compliance (taking into consideration the Lender's policies with
respect to capital adequacy), in any case by an amount deemed by the Lender to
be material, then, in any such case, the Borrower shall promptly pay the Lender
(or such corporation controlling the Lender), on its written demand, any
additional amount necessary to compensate the Lender (or such corporation) for
such additional cost, reduced amount receivable or reduction in rate of return
with respect to this Agreement, the Note or the Loans, together with interest
on such amount from the date demanded until payment in full thereof at the rate
per annum applicable to Loans, calculated on the basis of a 360-day year for
the actual days elapsed.  If the Lender becomes entitled to claim any
additional amount pursuant to this Section 2.10, the Lender shall promptly
submit to the Borrower a certificate as to any additional amount payable
pursuant to the first sentence of this Section 2.10, which amount shall be,
absent manifest error, presumed to be correct; provided, however, that the
determination thereof is made on a reasonable basis.  In determining such
amount, the Lender shall use any reasonable averaging and attribution methods.

         Section 2.11.  LIBOR Alternate Rate  In the event, and on each
occasion, that on the day of the commencement of a particular Interest Period,
the Lender determines in good faith (which determination shall be conclusive
and binding upon the Borrower) that (a) U.S. dollar deposits, in an amount
equal to the aggregate principal amount of the Loans which are outstanding
during such Interest Period, for delivery on the first day of such Interest
Period and for the number of days in such Interest Period, are not generally
available in the London Interbank Market or the circumstances affecting the
London Interbank Market make it impractical to determine LIBOR, or (b) any
Regulatory Change shall make it unlawful for the Lender to make or maintain
LIBOR with respect to any Loan or to fund any Loan at LIBOR in the London
Interbank Market or to give effect to its obligations hereunder, then the
outstanding principal amount of the Loans shall bear interest at an interest
rate equal to the Base Rate plus the Applicable Margin, unless and until the
Lender shall have determined in good faith (which determination shall be
conclusive and binding upon the Borrower) that the aforesaid circumstances no
longer exist, whereupon the interest rate applicable to such Loans shall be
converted back to an interest rate equal to LIBOR plus the Applicable Margin,
determined in the manner set forth above as of the commencement of the next
Interest Period.

         Section 2.12.  Conversion.  (A)  Upon the earlier to occur of the
Expiration Date or an Event of Default, the Lender may, in its sole discretion
and in addition to its other remedies available to it under this Agreement, the
Loan Documents or applicable law, subject to the payment of the applicable
Breakage Fees, if any, elect to Convert any or all of the Loans into fixed rate
conduit loans containing market terms to be determined by the Lender and
requiring monthly principal and interest payments based on a twenty-five (25)
year amortization period maturing on the Conversion Maturity Date.  All of the
Conversion Loans shall be cross-collateralized and cross-defaulted with full
recourse to the Borrower.





                                       20
<PAGE>   26
         (B)  The Borrower acknowledges that the Loan Documents for the Loans
contain numerous terms which will be inapplicable upon Conversion, including,
without limitation, the possible modification of some or all of the Loan
Documents to terminate or partially terminate the cross-collateralization and
cross-default provisions with respect to one or more of the Loans.  In
addition, it may be necessary to record a notice that the Conversion has
occurred in order to obtain appropriate title insurance coverage.  Therefore,
upon any Conversion, the Borrower shall (i) execute and deliver to the Lender
(a) appropriate documents in recordable form providing notice of Conversion;
and (b) amended and restated loan documents for the Loans containing the
interest, repayment and other terms described herein applicable to the
Conversion Loans following Conversion and otherwise conforming to the standard
loan documents then used by the Lender for commercial conduit real estate loans
with terms and collateral similar to the Conversion Loans, all as determined by
the Lender; (ii) transfer the Collateral Properties to one or more special
purpose bankruptcy-remote subsidiaries; (iii) establish such reserves as the
Lender may require, in its sole discretion, including, without limitation,
reserves for capital repairs and improvements, tenant improvements and leasing
commissions; and provide the Lender with such additional information,
documents, certificates, appraisals, opinions, Estoppel Certificates,
Subordination Agreements, third party and other reports (including, without
limitation, Building Condition Reports and Environmental Reports) and other
information with respect to the Borrower and/or the Collateral Properties as
the Lender may request.  Notwithstanding the foregoing, in the event that the
Lender elects to proceed with a Conversion, the Lender shall be entitled to
execute and record, without any approval or execution of the Borrower, a notice
that the Conversion has occurred.

         Section 2.13.    AIP-SWAG Collateral.  (a)  Lender has agreed to make
a Loan to Borrower which is, in part, secured by Collateral Properties owned by
AIP-SWAG.  On the Borrowing Date of that Loan, Lender has advanced to Borrower
Twenty Million Six Hundred Seventy Five Thousand Dollars ($20,675,000.00).
Borrower may request additional disbursements under that Loan of not more than
Two Million Four Hundred Twenty Five Thousand Dollars ($2,425,000) (the
"Additional Disbursement") subject to the terms of this Section 2.13.

         (b)     Upon and with a request by Borrower for an Additional
Disbursement, Borrower shall provide evidence in all respects satisfactory to
Lender that:  (i) additional rentals which support the Additional Disbursement
are derived from leases under which the lease term has commenced; (ii) the
lessees or tenants under such leases are acceptable to Lender; (iii) assuming
the Additional Disbursement, the requirements set forth in Sections 7.01 and
7.03 hereof are met; and, (iv) no Event of Default has occurred or is
continuing.

         (c)     Lender shall make no more than two Additional Disbursements
hereunder.  Borrower's right to request such Additional Disbursements shall
terminate 180 days from the Borrowing Date.  No Additional Disbursement shall
be made by Lender in an amount less than One Hundred Thousand ($100,000.00)
Dollars and the fee required under Section 2.09(A) hereof shall be paid by
Borrower to Lender with each such Additional Disbursement.

                   ARTICLE 3.  REPRESENTATIONS AND WARRANTIES

         In order to induce the Lender to enter into this Agreement and to
extend the financial accommodations hereunder, the Borrower hereby represents
and warrants to the Lender that:

         Section 3.01.  Organization and Powers; REIT Status.  The REIT
Borrower is a real estate investment trust duly organized and validly existing
and in good standing under the laws of the State of Texas. The AIP-SWAG is a
limited partnership duly organized and validly existing and in good standing
under the laws of the State of Delaware.  The Borrower is duly qualified to do
business as a foreign corporation or entity and is in good standing in each
jurisdiction (other than the state of its respective incorporation or
organization) in which the conduct of its respective business or the ownership
or operation of its respective properties or assets makes such qualification
necessary, except where the failure to so qualify would not have a Material
Adverse Effect.  The Borrower has full power and authority to own its
respective properties and assets and carry on its respective business as now
conducted. The REIT Borrower has not taken any action that would prevent it
from maintaining its qualification as a REIT.

         Section 3.02.  Power and Authorization.  (a)  The Borrower has full
power, right and legal authority to execute, deliver and perform its respective
obligations under this Agreement, the Note and such of the other Related

partnership, if applicable, and other actions necessary to authorize the
execution and delivery of, and the performance of its obligations under such
documents and to make borrowings by the Borrower under this Agreement, as the
case may be.  This Agreement, the Note and such of the other Related Documents
to which it is a party, constitute legal, valid and binding obligations of the
Borrower enforceable against it in accordance with their respective terms
subject to the effect of any applicable bankruptcy, insolvency, reorganization
or moratorium or similar laws affecting the rights of creditors generally.  No
consent of any person, and no consent, license, approval or authorization, or
registration or declaration with, any Governmental Authority, which has not
been obtained, taken or made (other than the financing statements and filings
required to be filed pursuant to this Agreement and the Related Documents,
which have been delivered to the Lender for filing on the Closing Date and on
the date of the closing of each Loan, as the case may be), is required in
connection with the execution, delivery or performance by the Borrower of this
Agreement, the Note or the other Related Documents to which it is a party, or
the making of borrowings by the Borrower under this Agreement.

         Section 3.03.  Permits; Compliance with Laws.  (A)  The Borrower has
all permits, licenses and governmental franchises and other authorizations from
all Governmental Authorities (collectively, the "Permits") that are necessary
to own and operate its business as presently being conducted and as
contemplated to be conducted immediately after the Closing Date and the date of
the closing of each Loan.  All such Permits are valid and subsisting and in
full force and effect.  (B)  The Borrower is in compliance with the terms of
such Permits and all statutes, laws, ordinances, governmental rules or
regulations (including Environmental Laws) and all judgments, orders or decrees
(federal, state, local or foreign) to which it is subject, except for
violations of which would not have a Material Adverse Effect.





                                       22
<PAGE>   28
     Section 3.04.  No Legal Bar. The execution, delivery and performance by the
Borrower of this Agreement, the Note and such of the other Related Documents to
which it is a party, and the making of borrowings hereunder by the Borrower, do
not and will not (i) violate or contravene any provisions of any existing law,
statute, rule, regulation or ordinance or charter document, (ii) violate or
contravene any provision of any order or decree of any court or Governmental
Authority to which the Borrower or any of its properties or assets are subject,
(iii) violate or contravene any provision of any mortgage, indenture, security
agreement, contract, undertaking or other agreement or instrument to which the
Borrower is a party or which purports to be binding upon either of it or any of
its properties or assets, except for violations or contravention of which would
not have a Material Adverse Effect, or (iv) result in the creation or imposition
of any Lien on any of the properties of the Borrower (other than as created
pursuant to the Loan Documents) pursuant to the provisions of any mortgage,
indenture, security agreement, contract, undertaking or other agreement or
instrument.

     Section 3.05.  Litigation.  There are no judgments or any litigation or
administrative proceedings of or before any court or Governmental Authority now
pending, nor, to the knowledge of the Borrower, are any such litigation or
proceedings now threatened, against the Borrower or any of its properties,
involving an individual claim in excess of $50,000 or claims in the aggregate in
excess of $100,000, except as disclosed in Schedule 3.05, nor, to the knowledge
of the Borrower, is there a valid basis for the initiation of any such
litigation or proceeding, including those set forth in Schedule 3.05.

         Section 3.06.  Solvency.  Immediately after giving effect to each of
the financing transactions contemplated hereby on and after each Borrowing
Date, the Borrower is solvent.  For purposes of this Section 3.06, the term
"solvent" means that, at the time of said determination, (i) the fair value of
such Person's assets exceeds the aggregate sum of its liabilities (including,
without limitation, contingent liabilities), (ii) such Person is able to pay
its debts as they mature, (iii) the property owned by such Person has a value
in excess of the total aggregate sum required to pay its debts, and (iv) such
Person has capital sufficient to carry on its business.

         Section 3.07.  The Collateral.  The chief places of business and chief
executive offices of the Borrower, and the offices where the Borrower keeps its
respective books and records concerning any of the Collateral is located at the
addresses specified in the Collateral Documents.  The Borrower owns the
Collateral in which it has granted a security interest and Lien in favor of the
Lender pursuant to the Loan Documents, free and clear of any Lien, security
interest charge or encumbrance, except as otherwise expressly permitted by
Section 6.02 hereof or the Related Documents or as otherwise disclosed in
Schedule 3.07 hereto.  All financing statements and filings required to be
filed, and all related required fees and taxes, have been delivered to the
Lender for filing and recording, and all other steps required to be taken have
been taken, so that upon proper filing and recording in the proper offices
Lender shall have, a valid, perfected, first priority continuing and
enforceable security interest in and Lien on the Collateral and such security
interest and Lien ranks prior to any other security interest in or Lien upon
the Collateral.

         Section 3.08.  Capitalization and Corporate Structure.  (A)  As of the
Closing Date, the authorized capital stock or partnership interest, as the case
may be, of the Borrower is validly issued, fully paid and nonassessable.  (B)
There are no outstanding subscriptions, warrants, options, convertible
securities or other rights (contingent or other), or commitments therefor, to
subscribe for, purchase or acquire any Securities or to pay any dividends on
any Securities, except in accordance with Section 6.07 hereof or as set forth
in Schedule 3.08, or to distribute to any holders of Securities any properties
or assets of the Borrower.  (C)  The Borrower does not have any Subsidiaries,
nor is it a partner in any partnership, joint venture or other similar entity.

         Section 3.09.  No Default.  The Borrower is not in default in any
respect in the payment or performance (i) of any of its respective material
obligations for the payment of money, or (ii) under any material franchise,
license or leasehold interest and no default has occurred and is continuing.

         Section 3.10.  No Secondary Liabilities.  There are no outstanding
contracts of guaranty or suretyship made by the Borrower, nor is the Borrower
subject to any other material contingent liability or obligation required to be
shown on the financial statements of the Borrower, except (a) as shown on such
financial statements referred to in Section 3.12 hereof, and (b) the
endorsement of negotiable instruments for deposit or collection or similar
transactions in the ordinary course of business.  To the knowledge of the
Borrower, the Borrower is not a party to any materially burdensome contract or
agreement, or subject to any charter or other corporate restriction adversely
affecting in any material manner its respective management, business, assets,
properties, assets, operations, prospects or condition (financial or other).

         Section 3.11.  Taxes.  The Borrower has timely filed, or caused to be
filed, all federal, state, local and foreign tax returns that are required to
be filed by it and has paid, or caused to be paid, all taxes, assessments,
interest and penalties thereon, on or before the due dates thereof, unless such
tax, assessment, charge, levy, claim is actively being contested in good faith
by appropriate proceedings and there has been set aside on the books of such
Person adequate reserves in accordance with GAAP applied with respect thereto.
There are no material claims pending or, to the knowledge of the Borrower,
proposed or threatened against the Borrower for past federal, state or local
taxes, except those, if any, as to which proper reserves, determined in
accordance with GAAP, are reflected in the most recent financial statements.
All such tax reports or returns fairly reflect the taxes of the Borrower for
the periods covered thereby.  No Internal Revenue Service or other tax audit of
the Borrower has occurred, is pending or, to the knowledge of the Borrower,
threatened, and the results of any completed audits are properly reflected in
the financial statements.

         Section 3.12.  Financial Statements and Condition.  The audited
consolidated financial statements of the REIT Borrower as of December 31, 1996
prepared by management and audited by a nationally recognized firm of certified
public accountants, true, complete and accurate copies of each of which were
delivered to the Lender on or before the Closing Date, (i) present fairly the
financial position of the Borrower on a consolidated basis as of the dates of
said statements, and the results of operations of the Borrower for the periods
covered by said statements of earnings





                                       24
<PAGE>   30
are in accordance with GAAP, except, in each case, as disclosed therein, (ii)
have been prepared in conformity in all material respects with GAAP, and (iii)
disclose all liabilities, direct and contingent, required to be shown in
accordance with such principles.  As of December 31, 1996, there were no
material obligations or liabilities, direct or indirect, fixed or contingent,
which are not reflected in such financial statements and that are required to
be so reflected thereon under GAAP.  No Material Adverse Change has occurred
since December 31, 1996.

     Section 3.13.  ERISA; Labor Relations. (A)  No Reportable Event has
occurred during the five-year period prior to the date on which this
representation is made or deemed made with respect to any Plan, and each Plan
has complied in all material respects with the applicable provisions of ERISA
and the Code.  The present value of all accrued benefits under each Plan
maintained by the Borrower or any ERISA Affiliate (based on those assumptions
used to fund the Plans) did not, as of the last annual valuation date prior to
the date on which this representation is made or deemed made, exceed the value
of the assets of such Plan allocable to such accrued benefits.  There are no
multiemployer plans.  Neither the Borrower nor any of its ERISA Affiliates has
had a complete or partial withdrawal from any multiemployer plan.  The present
value (determined using actuarial and other assumptions which are reasonable in
respect of the benefits provided and the employees participating) of the
liability of the Borrower and each ERISA Affiliate for post retirement benefits
to be provided to their current and former employees under Plans which are
welfare benefit plans (as defined in Section 3(1) of ERISA) does not, in the
aggregate, exceed the assets under all such Plans allocable to such benefits.
(B)  The Borrower is not a party to any collective bargaining agreement.  There
are no lockouts, strikes, labor disputes or other material controversies pending
between the Borrower and any of its employees, which in the aggregate, might
have a Material Adverse Effect.

         Section 3.14.  Environmental Matters.  Except as disclosed in Schedule
3.14 hereto, the Borrower and each respective parcel of real property owned or
leased by it are in material compliance with all Environmental Laws and
Requirements of Environmental Law; there are no conditions existing currently
or, to the knowledge of the Borrower, likely to exist that would subject the
Borrower to damages, penalties, injunctive relief or cleanup costs in an
aggregate amount exceeding $50,000 under any Environmental Matters or
assertions thereof, or which require or are likely to require cleanup, removal,
remedial action or other response pursuant to Environmental Laws by the
Borrower; the Borrower is not a party to any Environmental Claim or litigation
or administrative proceedings involving an individual claim in excess of
$50,000 or claims in the aggregate in excess of $50,000, nor so far as is known
by the Borrower, is any such litigation or administrative proceeding threatened
against the Borrower, which asserts or alleges that the Borrower has violated
or is violating Environmental Laws or Environmental Permits in any material
respect or that the Borrower is required to clean up, remove or take remedial
or other responsive action due to the disposal, depositing, storage, discharge,
leaking or other release of any hazardous substances or materials; neither the
Borrower nor any respective parcel of real property owned or leased by it are
subject to any Environmental Claim or judgment, decree, order or citation

the Borrower has not been named or listed as a potentially responsible party by

conditions, standards, prohibitions, requirements, obligations, schedules and

code, plan, order, decree or judgment relating to public health and safety,
worker health and safety and pollution or protection of the environment or any
notice or demand letter issued, entered, promulgated or approved thereunder,
except where the failure to so comply would not have a Material Adverse Effect;
the Borrower has not received notice (whether written or oral), specifying that
certain facts, events or conditions, interfere with or prevent continued
compliance with, or give rise to any liability involving an individual claim in
excess of $50,000 or claims in the aggregate in excess of $50,000 under any
law, common law or regulation, related to the manufacture, processing,
distribution, use, treatment, storage, disposal, transport or handling, or the
emission, discharge, release or threatened release into the environment, of any
pollutant, contaminant, or hazardous or toxic material or Waste; and there are
not now, nor to the knowledge of the Borrower have there ever been, materials
stored, spilled, deposited, treated, recycled or disposed of on, under or at
any parcel of real property owned or leased by the Borrower, or stored,
spilled, deposited, treated, recycled or disposed of at the direction of the
Borrower, present in soils or ground water, that would require cleanup, removal
or some other remedial action under Environmental Laws.

reports furnished in writing by, or on behalf of, the Borrower to the Lender in
connection with the negotiation and preparation of this Agreement and the other

agreement.

         Section 3.21.  Brokers.  The Borrower represents that it has not

or at such other address as the party giving such notice shall have been
advised of in writing for such purpose by the party to which the same is
directed.

         Section 9.02.  Survival of this Agreement.  All covenants, agreements,
representations and warranties made herein, or in the Loan Documents or in any
certificate delivered pursuant hereto or thereto shall survive the execution by
the Borrower and delivery to the Lender of this Agreement, the Note and the
other Loan Documents and the making and repayment of the Loans hereunder, and
shall continue in full force and effect so long as any Obligations of the
Borrower remains outstanding and unpaid or this Agreement remains in effect.

         Section 9.03.  Indemnity.  The Borrower agrees to defend, protect,
indemnify and hold harmless the Lender and each of its Affiliates, officers,
directors, employees, agents, attorneys and consultants (collectively called
the "Indemnitees") from and against any and all liabilities, obligations,
losses, damages, penalties, actions, judgments, suits, claims, costs, expenses
and disbursements of any kind or nature whatsoever (including, without
limitation, the reasonable fees and disbursements of counsel for such
Indemnitees incurred in connection with any action or proceeding between or
among the Borrower and any Indemnitee or between any Indemnitee and any third
party or otherwise, whether or not relating to any investigative,
administrative or judicial proceeding and whether or not such Indemnitees shall
be designated a party thereto), imposed on, incurred by, or asserted against
such Indemnitees (whether direct, indirect, special, consequential, punitive or
treble and whether based on any federal, state or local, or foreign, laws or
other statutory regulations, including, without limitation, Environmental Laws,
securities and commercial laws and regulations, under common law or at
equitable cause, or on contract or otherwise) in any manner relating to or
arising out of this Agreement or any of the Related Documents, or any act,
event or transaction related or attendant thereto or contemplated hereby, or
any action or inaction by any Indemnitee under or in connection therewith, any
commitment of the Lender hereunder, or the making of the Loans, or the
management of such Loans, or the use or intended use of the proceeds of any
Loan, advance or other financial accommodation provided hereunder, or any ERISA
liabilities, or the use or intended use of the Collateral Properties or any
accident or injury occurring on the Collateral Properties, or any claims
asserted against the Lender by reason of its alleged obligations under any
Lease, or the payment of any brokerage commission to anyone in connection with
funding the Loans, or any misrepresentation made by the Borrower to the Lender
in the Loan Documents, including, in each such case, any allegation of any such
matters, whether meritorious or not (collectively, the "Indemnified Matters");
provided, however, that the Borrower shall not have any obligation to any
Indemnitee hereunder with respect to Indemnified Matters directly caused by or
resulting primarily from the willful misconduct or gross negligence of such
Indemnitee.  The covenants of the Borrower





                                       47
<PAGE>   53
contained in this Section 9.03 shall survive the payment in full of all amounts
due and payable under this Agreement or any of the Loan Documents and the full
satisfaction of all other Obligations of the Borrower.

     Section 9.04.  Costs, Expenses and Taxes.  (a) The Borrower agrees to pay
on demand (i) all reasonable out-of-pocket costs and expenses incurred by the
Lender in connection with the preparation, execution, delivery, filing,
recording, and administration of this Agreement (including, without limitation,
the Conversion), each of the Related Documents, and any other documents,
instruments or agreements which may be delivered in connection with this
Agreement (including, without limitation, the reasonable fees and out-of-pocket
expenses of counsel for the Lender, and local counsel who may be retained by
said counsel) with respect thereto and with respect to advising the Lender as
to its rights and responsibilities under this Agreement (including, without
limitation, the Conversion), (ii) all costs and expenses in connection with all
third party reports, the audit, appraisal, valuation, investigation, and the
creation, perfection, priority or protection of the Lender's Liens against the
Collateral (including, without limitation, before and after the Conversion),
including, without limitation, all costs and expenses (A) to pay or discharge
taxes, Liens, security interests or other encumbrances levied, placed or
threatened against the Collateral and (B) for title and lien searches, title
insurance premiums, filing and recording fees and taxes, duplication costs and
corporate search fees, including, without limitation, all title and lien
searches, title insurance premiums, filing and recording fees and taxes
incurred in connection with the filing and recording of the Mortgages and the
Deeds of Trust, (iii) all out-of-pocket costs and expenses in connection with
the audits, inspections and investigations conducted pursuant to Section 2.12
and Section 5.09 hereof, and (iv) all costs and expenses (including, without
limitation, the reasonable fees and expenses of the Lender's counsel) of the
Lender in connection with the monitoring, refinancing and/or enforcement of
this Agreement (including, without limitation, the Conversion) and each of the
Related Documents and such other documents, instruments or agreements which may
be delivered in connection with this Agreement.

         (b)     Any and all payments by the Borrower under this Agreement or
the Note shall be made free and clear of and without deduction for any and all
present or future taxes, levies, imposts, deductions, charges or withholdings,
and all liabilities with respect thereto, excluding, in the case of the Lender,
taxes imposed on or in respect of its income (all such non-excluded taxes,
levies, imposts, deductions, charges, withholdings, and liabilities being
hereinafter referred to as "Taxes").  If the Borrower shall be required by law
to deduct any Taxes from or in respect of any sum payable hereunder to the
Lender, (i) the sum payable shall be increased as may be necessary so that,
after making all required deductions (including deductions applicable to
additional sums payable under this Section 9.04), the Lender receives an amount
equal to the sum it would have received had no such deductions been made, (ii)
the Borrower shall make such deductions, and (iii) the Borrower shall pay the
full amount deducted to the relevant taxation authority or other authority in
accordance with applicable law.

         (c)     The Borrower further agrees to pay any present or future stamp
or documentary taxes or any other excise or property taxes, charges, or similar
levies which arise in connection with the execution and delivery of this
Agreement, any of the Related Documents or any of the





                                       48
<PAGE>   54
other instruments, documents or agreements executed and/or delivered in
connection herewith or therewith, or any payment made hereunder or in
connection herewith (hereinafter collectively referred to as "Other Taxes").

         (d)     The Borrower shall indemnify the Lender for the full amount of
Taxes and Other Taxes (including, without limitation, any Taxes or Other Taxes
imposed by any jurisdiction on amounts payable by the Borrower under this
Section 9.04) paid by the Lender and any liability (including penalties,
interest, and expenses) arising therefrom or with respect thereto, whether or
not such Taxes or Other Taxes were correctly or legally asserted.  This
indemnification shall be made within 30 days from the date the Lender makes
written demand therefor.  A certificate as to any additional amount payable to
the Lender under this Section 9.04 submitted to the Borrower by the Lender
shall show in reasonable detail the amount payable and the calculations used to
determine such amount and shall, absent manifest error, be final, conclusive
and binding upon each of the parties hereto.

         (e)     Without prejudice to the survival of any other agreement of
the Borrower hereunder, the agreements and obligations of the Borrower
contained in this Section 9.04 shall survive the payment in full of all amounts
due and payable under this Agreement or any of the Related Documents and the
full satisfaction of all other Obligations of the Borrower.

         Section 9.05.  Further Assurances.  (a) At any time and from time to
time, upon the request of the Lender, the Borrower shall execute, deliver and
acknowledge, or cause to be executed, delivered and acknowledged, such further
documents and instruments and do such other acts and things as the Lender may
reasonably request in order to effect fully the intent and purposes of this
Agreement and the Related Documents, and any other agreements, instruments and
documents delivered pursuant hereto or in connection with the making of the
Loans, in proper form for recording and otherwise in form and substance
reasonably satisfactory to the Lender and its counsel.

         (b)     The Borrower agrees that from time to time, at its expense, it
shall promptly execute and deliver all further instruments and documents, and
take all further action, that may be necessary or appropriate, or that the
Lender may reasonably request, in order to create, evidence, perfect or
preserve any security interest or Lien granted or purported to be granted
hereby or by any Loan Document or to enable the Lender to exercise and enforce
its rights and remedies hereunder or under any Loan Document with respect to
any Collateral.

         Section 9.06.  Amendment and Waiver.  No amendment or waiver of any
provision of this Agreement or any of the Related Documents to which the Lender
is a party, nor any consent to any departure by the Borrower therefrom, shall
in any event be effective unless the same shall be in writing and signed by the
Lender, and then such waiver or consent shall be effective only in the specific
instance and for the purpose for which given; provided, however, that no
amendment, waiver or consent, shall, unless in writing and signed by all
holders of the Note do any of the following: (i) increase the Commitment, (ii)
reduce the principal of, or premiums or interest on, the Note or the funding
fee payable in accordance with Section 2.09 hereunder, (iii) postpone any date
fixed for any payment of principal of, or interest on, the Note or such funding





                                       49
<PAGE>   55
fee or any other amount due hereunder or under any Loan Document to any holder
of the Note, or waive any default in the payment of principal, interest or any
other amount due hereunder or under any Loan Document to which such holder of
the Note is a party, (iv) release any material portion of the Collateral, or
(v) amend this Section 9.06 or any other provision requiring the consent of all
of the holders of the Note.  No failure on the part of the Lender or any holder
of the Note to exercise, and no delay in exercising, any right, power or
privilege hereunder or under any of the Related Documents shall operate as a
waiver thereof, nor shall a single or partial exercise thereof preclude any
other or further exercise thereof or the exercise of any other right, power or
privilege.  No notice to or demand on the Borrower in any case shall entitle
the Borrower to any other or further notice or demand in the same, similar or
other circumstances.

         Section 9.07.  Remedies Cumulative.  This Agreement, the Related
Documents and the Obligations of the Borrower hereunder and thereunder are in
addition to and not in substitution for any other Obligations of the Borrower
or security interests granted by the Borrower now or hereafter held by the
Lender and shall not operate as a merger of any contract or debt or suspend the
fulfillment of or affect the rights, remedies or powers of the Lender in
respect of any such Obligation or security interest held by the Lender for the
fulfillment thereof.  The rights and remedies provided in this Agreement and in
any Related Document are cumulative and not exclusive of any other rights or
remedies provided by law.

         Section 9.08.  Marshaling, Recourse to Security: Payments Set Aside.
The Lender shall not be under any obligation to marshal any assets in favor of
the Borrower or any other party or against or in payment of any or all of the
Obligations of the Borrower to the Lender hereunder or under the Related
Documents or otherwise.  Recourse to security shall not be required at any
time.  To the extent that the Borrower makes a payment or payments to the
Lender, or the Lender enforces its security interests or exercises its rights
of setoff, and such payment or payments or the proceeds of such enforcement or
setoff or any part thereof are subsequently invalidated, declared to be
fraudulent or preferential, set aside and/or required to be repaid to a
trustee, receiver or any other party under any bankruptcy law, state or federal
law, common law or equitable cause, then to the extent of such recovery, the
obligation or part thereof originally intended to be satisfied, and all Liens,
rights and remedies therefor, shall be revived and reinstated and continued in
full force and effect as if such payment had not been made or such enforcement
or setoff had not occurred.

         Section 9.09.  Setoff.  In addition to any rights and remedies of the
Lender now or hereafter provided by law, the Lender shall have the right,
without prior notice to the Borrower, any such notice being expressly waived by
the Borrower to the extent permitted by applicable law, on the occurrence and
during the continuation of any Event of Default to setoff and apply against any
Obligation, whether matured or unmatured, of the Borrower, any amount owing
from the Lender to the Borrower, at or at any time after the happening of any
such Event of Default, and such right of setoff may be exercised by the Lender
against the Borrower or against any trustee in bankruptcy,
debtor-in-possession, assignee for the benefit of creditors, receiver or
execution, judgment or attachment creditor, notwithstanding the fact that such
right of setoff shall not have been exercised by the Lender before the making,
filing or issuance, or service on the Lender of, or of notice of, any such
event or proceeding.

         Section 9.10.  Binding Effect.  This Agreement shall become effective
when it shall have been executed by the Borrower and the Lender, and thereafter
shall be binding upon and inure to the benefit of the Borrower and the Lender
and their respective successors and assigns; provided, however, that the
Borrower shall not have the right to assign its rights hereunder or any
interest herein without the prior written consent of the Lender.  For the
purposes of this Section 9.10, an assignment shall be deemed to include (i) if
the Borrower is a corporation, the voluntary or involuntary sale, conveyance or
transfer of the Borrower's Securities (or the Securities of any corporation
directly or indirectly controlling the Borrower by operation of law or
otherwise) or the creation or issuance of a new stock by which an aggregate of
more than ten percent (10%) of the Borrower's Securities shall be vested in a
party or parties who are not now shareholders, (ii) if the Borrower is a
partnership, the change, removal or resignation of a general partner or
managing partner, or (iii) if the Borrower is a limited liability company, the
change, removal or resignation of a managing member.

         Section 9.11.  Applicable Law.  This Agreement and the rights and
obligations of the parties hereunder shall be governed by, and construed and
interpreted in accordance with, the substantive law of the State of New York,
without regard to its choice of law provisions.

         Section 9.12.  Consent to Jurisdiction and Service of Process; Waiver
of Jury Trial.   All judicial proceedings brought against the Borrower or the
Lender with respect to this Agreement or any Related Document may be brought in
any state or federal court of competent jurisdiction in the State of New York
and, by its execution and delivery of this Agreement, the Borrower accepts, for
itself and in connection with its properties, generally and unconditionally,
the exclusive jurisdiction of the aforesaid courts, and irrevocably agrees to
be bound by any final judgment rendered thereby in connection with this
Agreement or any of the Related Documents from which no appeal has been taken
or is available.  The Borrower irrevocably consents to the service of process
of any of the aforementioned courts in any such action or proceeding by the
mailing of copies thereof by registered or certified mail, postage prepaid, to
its notice address specified in Section 9.01 hereof, such service to become
effective five (5) days after such mailing.  EACH OF THE BORROWER AND THE
LENDER HEREBY KNOWINGLY, INTENTIONALLY AND IRREVOCABLY WAIVE (a) TRIAL BY JURY
IN ANY ACTION OR PROCEEDING WITH RESPECT TO THIS AGREEMENT OR ANY RELATED
DOCUMENT, AND (b) ANY OBJECTION (INCLUDING, WITHOUT LIMITATION, ANY OBJECTION
TO THE LAYING OF VENUE OR BASED ON THE GROUNDS OF FORUM NON CONVENIENS) WHICH
IT MAY NOW OR HEREAFTER HAVE TO THE BRINGING OF ANY SUCH ACTION OR PROCEEDING
WITH RESPECT TO THIS AGREEMENT OR ANY RELATED DOCUMENT IN ANY JURISDICTION SET
FORTH ABOVE.  Nothing herein shall affect the right of the Lender to serve
process in any other manner permitted by law.

         Section 9.13.  Inconsistencies.  This Agreement and each of the Loan
Documents shall be construed to the extent reasonable to be consistent, one
with the other, but to the extent that the terms and conditions of this
Agreement or any other Loan Document are actually inconsistent with the terms
and conditions of any Loan Document, the terms and conditions of this Agreement
shall govern.

         Section 9.14.  Performance of Obligations.  The Borrower acknowledges
and agrees that the Lender may, but shall have no obligation to, make any
payment or perform any act required of the Borrower under this Agreement or any
Related Document or take any other action which the Lender in its discretion
deems necessary or desirable to protect or preserve the Collateral, including,
without limitation, any action to pay or discharge taxes, Liens, security
interests or other encumbrances levied or placed on or threaten to be placed on
any Collateral.

         Section 9.15.  Assignment; Participation.  The Lender may assign (by
novation or otherwise) or participate all or a proportionate part of its
rights, obligations and interests in the Loans and its rights hereunder and
under the Related Documents without restriction.  The Lender may, prior to or
after the execution of this Agreement syndicate the Loans with one or more
financial institutions, who will become parties to this Agreement, in which
case the Lender will be the sole and exclusive agent for such other financial
institutions upon such terms and conditions as the Lender deems appropriate.
The Borrower hereby agrees to reasonably cooperate with the Lender, at the
Borrower's expense, to effect assignments and/or participations made with
respect hereto.

         Section 9.16.  Confidentiality.  The Lender shall maintain the
confidential nature of, and shall not use or disclose, the Borrower's
confidential financial information, without first obtaining the Borrower's
written consent, which consent shall not be unreasonably withheld or delayed.
Nothing in this Section 9.16 shall require the Lender to obtain the consent of
the Borrower, before exercising any of its rights under the Related Documents
upon the occurrence of a Default or Event of Default.  The obligations of the
Lender shall in no event apply to: (i) providing information about the Loans or
any party to any Related Document to any actual or potential assignee or
participant contemplated in Section 9.15 hereof; (ii) any situation in which
the Lender, in the sole discretion of the Lender, is required by law or
required or requested by any governmental, regulatory or supervisory authority
or official to disclose information; (iii) providing information to counsel to
the Lender in connection with the transactions contemplated by the Related
Documents; (iv) providing information to independent auditors retained by the
Lender; (v) any information that is in or becomes part of the public domain
otherwise than through a wrongful act of the Lender or any employees or agents
thereof; (vi) any information that is in the possession of the Lender prior to
receipt thereof from the Borrower or any other Person known to the Lender to be
acting on behalf of the Borrower; (vii) any information that is independently
developed by the Lender; and (viii) any information that is disclosed to the
Lender by a third party that has no obligation of confidentiality with respect
to the information disclosed.

         Section 9.17.  Construction.  The parties hereto acknowledge that each
party and its counsel have reviewed this Agreement and each of the Loan
Documents and that the normal rule of construction to the effect that any
ambiguities are to be resolved against the drafting party shall not be employed
in the interpretation of this Agreement or any of the Loan Documents.

         Section 9.18.  Entire Agreement; Binding Effect.  This Agreement,
taken together with all of the Related Documents and all certificates and other
documents delivered by the Borrower to the Lender, embodies the entire
agreement and, except as otherwise contemplated herein, supersedes all prior
agreements, written and oral, relating to the subject matter hereof.

         Section 9.19.  Severability.  Any provision of this Agreement which is
prohibited, unenforceable or not authorized in any jurisdiction shall, as to
such jurisdiction, be ineffective to the extent of such prohibition,
unenforceability or non-authorization without invalidating the remaining
provisions hereof or affecting the validity, enforceability or legality of such
provision in any other jurisdiction.

         Section 9.20.  Headings.  Section headings in this Agreement are
included herein for convenience of reference only and shall not constitute a
part of this Agreement for any other purpose.

         Section 9.21.  Execution of Counterparts.  This Agreement may be
executed in any number of counterparts and by different parties hereto in
separate counterparts, each of which when so executed shall be deemed to be an
original and all of which when taken together shall constitute one and the same
agreement.

         Section 9.22.  Limitation of Liability.  No claim may be made by the
Borrower or any other Person against the Lender or its Affiliates, directors,
officers, employees, attorneys or agents for any special, indirect,
consequential, punitive or treble damages in respect of any claim for breach of
contract or any other theory of liability arising out of or related to the
transactions contemplated by this Agreement or any other Related Documents, or
any act, omission or event occurring in connection herewith or therewith; and
the Borrower hereby waives, releases and agrees not to sue upon any claim for
any and all special, indirect, consequential, punitive or treble damages,
whether or not accrued and whether or not known or suspected to exist in its
favor.
