ITEM 5.           OTHER EVENTS.

         ASR Investments Corporation (the "Company") has entered into agreements
to  acquire,  subject  to the  satisfaction  and  waiver  of  certain  terms and
conditions,  from independent  third parties three apartment  communities  ("MTP
Properties")  containing  a total of 900 units in the Dallas,  Texas  area.  The
sellers would contribute the properties to Hertage Communities L.P. of which the
Company is the  general  partner.  The  Company  would (i)  assume or  refinance
mortgage debt totalling $18,035,000,  (ii) issue 374,581 shares of the Company's
common stock, (iii) issue limited partnership units in Heritage Communities L.P.
that are convertible  into 27,721 shares of the Company's common stock after one
year, and (iv) pay $2,400,000 in cash to the sellers.  Below is a description of
the three apartment communities.

         Gentry Place.  The Gentry Place  Apartments,  located in Grand Prairie,
Texas (a suburb of Dallas, Texas), are comprised of 360 units built in 1984. The
company  anticipates  completing  the  acquisition of the property by September,
1997. As of June 30, 1997, the Gentry Place  Apartments  had an average  monthly
rent of $568, or $.62 a square foot per month, and an average  occupancy rate of
96%. The property's main competition for tenants comes from existing multifamily
apartment  projects in the  surrounding  Grand Prairie area of west Dallas.  The
Company plans to substantially  improve the property by investing  approximately
$600,000 in improvements.  These improvements  include replacement of all roofs,
replacing  approximately 50% of the flooring,  complete repaint of the property,
installation  of access  gates and  perimeter  fencing and  installation  of ice
makers in 100% of the units.

         Park on  Preston  The Park on  Preston  Apartments,  located in Dallas,
Texas,  are  comprised  of 286  units  built in 1983.  The  Company  anticipates
completing the  acquisition  of the property by September,  1997. As of June 30,
1997,  the Park on Preston  Apartments  had an average  monthly rent of $521, or
$.82 a  square  foot  per  month,  and an  average  occupancy  rate of 95%.  The
property's  main  competition  for  tenants  comes  from  existing   multifamily
apartment  projects in the surrounding  Plano area north of Dallas.  The Company
plans to substantially improve the property by investing  approximately $600,000
in improvements.  These improvements includes replacing approximately 50% of the
flooring,  complete  repaint of the property,  washer and dryer  installation in
approximately  50% of the units,  and  installation  of ice makers in 70% of the
units.

         Smith Summit. The Smith Summit Apartments,  located in Mesquite,  Texas
(a suburb of Dallas,  Texas),  are  comprised  of 254 units  built in 1983.  The
Company  anticipates  completing  the  acquisition of the property by September,
1997. As of June 30, 1997, the Smith Summit  Apartments  had an average  monthly
rent of $605, or $.63 a square foot per month, and an average  occupancy rate of
96%. The property's main competition for tenants comes from existing multifamily
apartment projects in the surrounding  Mesquite area of east Dallas. The Company
plans to substantially improve the property by investing  approximately $250,000
in improvements.  These improvements include replacing  approximately 50% of the
flooring, exterior paint touchup of the property, and installation of ice makers
in 100% of the units.

<PAGE>
                          INDEPENDENT AUDITORS' REPORT

To the Board of Directors and Stockholders
ASR Investments Corporation:

   We have audited the accompanying  combined historical summary of revenues and
certain  operating  expenses (the "Summary") of the MTP Properties (as described
in  Note  2),  for  the  year  ended  December  31,  1996.  The  Summary  is the
responsiblity of the management of the MTP Properties.  Our responsibility is to
express an opinion on the Summary based on our audit.

   We  conducted  our  audit in  accordance  with  generally  accepted  auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the Summary is free of material misstatement.
An audit includes  examining,  on a test basis,  evidence supporting the amounts
and disclosures in the Summary.  An audit also includes assessing the accounting
principles  used  and  significant  estimates  made  by  management,  as well as
evaluating the overall Summary presentation.  We believe that our audit provides
a reasonable basis for our opinion.

   The accompanying  Summary was prepared for the purpose of complying with Rule
3-14  of  Regulation  S-X  of  the   Securities  and  Exchange   Commission  for
incorporation in ASR Investments  Corporation's  Registration  Statement on Form
S-3 as  described  in Note 1 to the Summary and is not intended to be a complete
presentation of the MTP Properties' revenues and expenses.

   In our opinion,  such Summary presents fairly, in all material respects,  the
combined revenues and certain operating  expenses,  as defined above, of the MTP
Properties  for the year ended  December 31, 1996, in conformity  with generally
accepted accounting principles.

                NOTES TO COMBINED HISTORICAL SUMMARY OF REVENUES
                         AND CERTAIN OPERATING EXPENSES
                      FOR THE YEAR ENDED DECEMBER 31, 1996
               AND THE SIX MONTHS ENDED JUNE 30, 1997 (UNAUDITED)


1. BASIS OF PRESENTATION

   The combined  historical  summary of revenues and certain operating  expenses
(the "Summary") has been prepared in accordance with Rule 3-14 of Regulation S-X
of the Securities and Exchange  Commission  ("Rule 3-14").  The Summary reflects
the historical  revenues and certain  operating  expenses of the three apartment
communities  as  listed  in  Note  2 (the  "MTP  Properties").  ASR  Investments
Corporation  ("ASR") has entered into  agreements to acquire the MTP  Properties
from  unaffiliated  third  parties.  In accordance  with Rule 3-14,  the Summary
includes  certain  operating  and  maintenance  costs,  real  estate  taxes  and
insurance expenses,  but excludes mortgage interest,  depreciation and corporate
expenses as they are dependent upon a particular owner,  purchase price or other
financial  arrangement.  Accordingly,  the expenses reflected in the Summary may
not be comparable to the expenses to be incurred by ASR in the operations of the
properties.  ASR is not aware of any  material  factors  relating  to the Winton
Properties other than those set forth herein that would cause the Summary not to
be indicative of the future operating results of the properties.

   In the opinion of management,  the unaudited  combined  historical summary of
revenues and certain  operating  expenses for the six months ended June 30, 1997
includes all adjustments (consisting of normal recurring adjustments) considered
necessary  for a fair  presentation  for such period.  These  interim  operating
results are not  necessarily  indicative of the results that may be expected for
the entire year.

   The  Summary  has been  prepared on the  accrual  method of  accounting.  The
apartment  communities have operating leases with terms generally of one year or
less. Rental income is recognized as earned.

3. USE OF ESTIMATES

accounting principles requires management to make estimates and assumptions that
affect some of the amounts  reported in the consolidated  financial  statements.
Actual results could differ from those estimates.

<PAGE>
                Unaudited Pro Forma Combined Financial Statements

   The following  unaudited pro forma combined income  statements give effect to
(a)  the  following   transactions   (collectively   the  "Previously   Reported
Transactions")  that  occurred  during the period  from April 1, 1997 to May 30,
1997: (i) the  acquisition  of the Winton  Properties,  (ii) the  acquisition of
Winton & Associates,  (iii) the acquisition of Pima Mortgage Limited Partnership
and Pima Realty Advisors,  Inc. (the "Pima  Entities"),  (iv) the acquisition of
London Park Apartments,  (v) the acquisition of the remaining 85% interest in La
Privada  Apartments  L.L.C.  and the related sale of the  interests in the other
five joint ventures, (vi) the acquisitions of Ivystone/Woodsedge  Apartments and
The Court  Apartments,  and (vii) the issuance of 187,847 shares of Common Stock
for cash in April and May; and (b) the pending  acquisition  of three  apartment
communities (the "MTP  Properties")  from a group of independent  third parties.
The pro forma  combined  income  statements for the year ended December 31, 1996
and the six months ended June 30, 1997 have been  prepared as if the  Previously
Reported  Transactions  and the  acquisition  of the  MTP  Properties  had  been
consummated as of January 1, 1996.  The pro forma  combined  balance sheet as of
June 30, 1997 gives effect to the acquisition of the MTP Properties and has been
prepared  as if the  acquisition  had  occurred  on June 30,  1997.  Adjustments
necessary to reflect these  assumptions  and to restate the historical  combined
financial  statements are presented in the Pro Forma Adjustments columns and are
described in the Notes thereto.

   The  historical  financial  information  for the Company is derived  from the
audited consolidated  financial statements of the Company as of and for the year
ended December 31, 1996 and the unaudited  consolidated  financial statements as
of and for the  six  months  ended  June  30,  1997.  The  historical  financial
information  for the properties and entities  acquired is derived from unaudited
financial  statements  of the  properties  or  entities,  as adjusted to reflect
certain preacquisition transactions.

   The unaudited pro forma combined  financial  statements  are not  necessarily
indicative  of what the actual  financial  position  would have been at June 30,
1997 or the actual  results of operations  for the year ended  December 31, 1996
and the six months  ended June 30,  1997 had the  acquisitions  occurred  on the
assumed  dates  described  above,  nor does it  purport  to  present  the future
financial position or results of operations of the Company.

for the  Transferor  Partners at the Closing (the  Registration  Statement,  the

pursuant to the Custody  Agreement.  Following the Commitment Date the tender of
Transferor Partnership Interests shall be irrevocable.

                  (e) Consent to  Admission  of REIT as  Partner.  The Letter of
Transmittal  shall provide that each Transferor  Partner  tendering a Transferor
Partnership  Interest in  Transferor  consents to the admission of the REIT as a
substituted  limited  partner upon the purchase of such  Transferor  Partnership
Interest.  MTP, as general partner of Preston Park LP, consents to the admission
of the REIT as a  substituted  limited  partner of  Transferor as of the Closing
Date.   Promptly   following  the  Closing  Date,   Transferor  shall  file  any
certificates  necessary to reflect the  admission  of the REIT as a  substituted
limited partner.

                  (f) Term.  The  Exchange  Offer  shall  remain  open until the
commitment  date,  which  shall be 5:00 p.m.,  Dallas,  Texas time on August 11,

all or a portion of distributions as a general partner in Transferor to the REIT
in exchange for shares of REIT Stock  pursuant to the Exchange Offer on the same
terms and subject to the same  conditions as set forth in Section 1.1 above.  At
the Closing,  the REIT shall accept for payment all  assignments of the right to
receive distributions as a general partner tendered by MTP in Transferor. If the
tender of the right to receive general partner  distributions  is accepted,  the
REIT shall acquire all right,  title and interest to all  distributions  made by
Transferor  with  respect to the  interest  acquired,  but the REIT shall not be
substituted  as a general  partner.  MTP shall remain as the general  partner of
Transferor.

         1.3 Internal Revenue Code Section 754 Election. Unless Transferor has a
valid  election  in  place  pursuant  to  Internal  Revenue  Code  Section  754,

taxable year in which the Exchange Offer is consummated.

partners of Heritage LP.  Transferor shall contribute and convey the Property to

hereof.  Pursuant to the terms of the Partnership Agreement,  the LP Units shall
be  exchangeable  for REIT Stock at any time following the first  anniversary of
the Closing Date.  Pursuant to the Asset Transfer  Registration  Agreement,  the
REIT shall agree to register for resale under federal securities laws the shares
of REIT Stock to be issued upon conversion of the LP Units.

         2.2      Contribution of Property to Heritage LP.

                  (a)  Capital  Contributions.  On the Closing  Date,  the REIT,
Heritage SGP and Transferor  shall make the following  capital  contributions to
Heritage LP:

                           (i) The  REIT  and  Heritage  SGP  shall  make a cash
capital   contribution   equal  on  an  aggregate  basis  to  the  REIT  Capital
Contribution which shall be the sum of:

                                    (A) that portion of the Mortgage  Debt to be
repaid or  cancelled  by  Heritage  LP in  accordance  with  Section  2.3 hereof
including, without limitation, any prepayment fees or premiums,  assumption fees
and other costs associated therewith, plus

                                    (B)  the  amount  required  to  satisfy  any
monetary liens which the REIT elects to satisfy pursuant to Section 2.3(d), plus

                                    (C) the Property  Closing  Costs paid and to
be paid by Heritage LP or the REIT  pursuant to Section 8.9,  plus or minus,  as
appropriate

                                    (D) the Prorations, plus

                                    (E) all costs and  expenses  incurred and to
be incurred by Heritage  LP, the REIT or Heritage SGP (on behalf of Heritage LP)
in the performance of its due diligence hereunder, plus

                                    (F) any  amounts  required  to  satisfy  the
obligations  of the  REIT or  Heritage  SGP to  make  capital  contributions  to

<PAGE>
                                    (G) cash in the  amount of the Cash  Payment
(as defined herein).

                           (ii)  Transferor  shall  contribute  and  convey  the
Property owned by Transferor to Heritage LP as hereinafter provided subject only
to the Transferred Debt as described in Section 2.3 hereof.

                           (iii) Notwithstanding the foregoing,  if, taking into
consideration  the proposed  contributions  to the capital of Heritage LP by the
REIT,  Heritage SGP, and  Transferor in accordance  with Section  2.2(a) hereof,
Heritage LP would not be consolidated with the REIT for financial accounting and
reporting purposes because the respective  Partnership  Interests of the REIT or
Heritage  SGP in  Heritage LP is  insufficient,  then at the Closing the REIT or
Heritage SGP may contribute  cash to Heritage LP in exchange for an amount of GP
Units equal to such cash contribution divided by the REIT Stock Price. Such cash
will be contributed in the minimum amount sufficient to permit Heritage LP to be
consolidated with the REIT for financial accounting and reporting purposes.

                  (b)  Distribution  of Cash and LP Units.  In exchange  for the
capital  contribution  made by  Transferor  provided in Section  2.2(a)  hereof,
Heritage LP shall distribute the following on the Closing Date:

                           (i) Cash Payment.  At the Closing,  Transferor  shall
receive by wire transfer an amount (the "Cash  Payment") equal to the sum of (i)
the Cash  Allocation set forth on Schedule V attached  hereto and (2) such other
escrowed amounts held by Lender including,  but not limited to, taxes, insurance
and such  other  reserves  held by Lender on  Transferor's  behalf if elected by
Transferor pursuant to Section 8.15(a) herein, less the Earnest Deposit.

                           (ii) LP Units. At the Closing, Transferor, or certain
partners of Transferor designated by Transferor on Schedule VIII attached hereto
as updated  pursuant to Section  6.2(a)  hereof,  shall  collectively  receive a
number  of LP  Units  that  shall be equal  to (A) the  difference  between  the
Exchange  Value  attributable  to Transferor  and the amount of the Cash Payment
pursuant to clause (i), divided by (B) the REIT Stock Price.

                  (c) Distribution of GP Units. In exchange for the REIT Capital
Contribution  provided in Section 2.2(a) hereof,  Heritage LP shall issue on the
Closing  Date to the REIT and  Heritage  SGP a number of GP Units  (rounded to a
whole unit)  equal to the REIT  Capital  Contribution  divided by the REIT Stock
Price  allocated  between  them on a pro rata basis based upon their  respective
contributions.

         2.3      Assumption of Mortgage Debt.

                  (a)  Mortgage  Debt.  The  REIT,  Heritage  LP and  Transferor
acknowledge and agree that the Property is subject to the Mortgage Debt from the
lender (the "Lender") as described on Schedule II attached hereto.  The Property
shall be acquired by Heritage LP subject
                                        6
<PAGE>
to the  Mortgage  Debt,  provided  that the Lender of such  Mortgage  Debt shall
execute a consent,  estoppel letter,  transfer agreement,  and modification with
respect to such  Mortgage  Debt as shall be  acceptable  to Heritage LP,  acting
reasonably;  provided,  however, the Lender will not be required to amend any of
the material legal or business terms of the Mortgage Debt.

                  (b)  Lender  Consent.  From  and  after  the date  hereof  and
continuing for 60 days  thereafter (the "Lender  Consent  Period"),  the parties
shall  proceed  in good  faith and with due  diligence  to attempt to secure any
lender consent and estoppel letter from the Lender and to negotiate any transfer
agreement  or  modifications  to the Loan  Documents in order for Heritage LP to
acquire the Property  subject to such Mortgage Debt.  Heritage LP agrees that it
shall accept the Property subject to the Mortgage Debt, provided that the Lender
agrees that such Mortgage Debt shall be  non-recourse to Heritage LP on the same
terms that such Mortgage Debt is currently  non-recourse  to Transferor  and the
Lender executes the agreements contemplated by Section 2.3(a). Any Mortgage Debt
to which the Property is subject upon transfer to Heritage LP is herein referred
to as "Transferred Debt."

                  (c) Refinancing of Mortgage Debt. In the event that the Lender
does not agree to the transfer of the Mortgage Debt as  contemplated  by Section
2.3(a) and Section 2.3(b), or if for any reason Heritage LP is unable to acquire
the Property  subject to the  Mortgage  Debt within the Lender  Consent  Period,
Heritage  LP shall  have the right to (i)  refinance  all or a  portion  of such
Mortgage  Debt  on  terms  it  determines  to be  acceptable  to it in its  sole
discretion;  (ii) pay all or any portion of such Mortgage Debt from the proceeds
of the REIT Capital  Contribution;  or (iii)  terminate  this  Agreement,  which
rights shall be exercised within the Lender Consent Period.

                  (d)  Indebtedness  Other Than Mortgage Debt.  Transferor shall
satisfy all pecuniary  encumbrances  (other than the Mortgage Debt) or otherwise
have all such  encumbrances  removed as liens  against the Property on or before
the Closing at its own expense.  Transferor shall not place any consensual lien,
encumbrance or easement against the Property  following the date of execution of
this Agreement  without the prior written  consent of the REIT, such consent not
to be unreasonably withheld or delayed. If Transferor fails to satisfy or remove
any  monetary  lien on or prior to  Closing,  the REIT may  proceed  to retain a
portion of the  Exchange  Value  equal to the amount of the  monetary  lien (the
"Holdback  Amount") and reduce the Exchange  Value of the Property  accordingly.
The  Holdback  Amount  shall be paid to  Transferor  at such time as  Transferor
extinguishes  such  monetary  lien.  In  the  event  that  Transferor  does  not
extinguish  such  monetary  lien within 120 days of the Closing  Date,  the REIT
shall apply the Holdback Amount to satisfy the monetary lien.  Transferor  shall
be required to deposit any additional  funds at Closing to satisfy any remaining
monetary liens against the Property.

         2.4 Earnest Money Deposit. Within five (5) days following the Execution
Date,  the REIT shall  deposit  $50,000 in escrow  with the Title  Company  (the
"Earnest  Deposit")  on account of the REIT  Capital  Contribution.  The Earnest
Deposit shall be placed in an interest-
                                        7
<PAGE>
bearing  account.  At the Closing,  the Earnest Deposit shall be applied against
the Cash Payment. In the event this Agreement is terminated for any reason other
than as a result of a  termination  pursuant  to Section  10.3(c),  the  Earnest
Deposit required by this Section 2.4 shall be returned to the REIT. In the event
this  Agreement is  terminated by Transferor  pursuant to Section  10.3(c),  the
Earnest  Deposit  required by this Section 2.4 shall be paid to MTP on behalf of
Transferor.

Transferor  represents and warrants that the information so supplied,  as it may

untrue statement of a material fact or omit to state a material fact required to

circumstances under which they were made, not misleading.

         3.5 Amendments to the Registration Statement.  If, at any time prior to
the  Expiration  Date,  it  shall  be  necessary  to  amend  or  supplement  the
Registration  Statement to correct any statement or omission with respect to the
REIT, MTP,  Transferor or their  subsidiaries  or assets,  or in order to comply
with any applicable  legal  requirements,  Transferor shall supply the necessary

                         REPRESENTATIONS AND WARRANTIES
                         ------------------------------

         4.1 Transferor Representations and Warranties. As a material inducement
to the REIT  Parties  to  execute  this  Agreement  and to the REIT  Parties  to
consummate the transactions  contemplated hereunder,  Transferor and MTP jointly
and  severally  represent and warrant to the REIT Parties with respect to itself
and the Property, that as of the date hereof and as of the Closing Date:

                  (a) Transferor Organizational Representations and Warranties.

                           (i) Organization  and Authority.  Transferor has been
duly  organized and is validly  existing and in good standing  under the laws of
its jurisdiction of organization and, if different,  is qualified to do business
and in good  standing in the state in which the Property is located.  Transferor
has the full right and authority to enter into this  Agreement.  Transferor  has
the full and right authority to transfer the Property and to consummate or cause
to be consummated the transactions  contemplated herein. This Agreement has been
duly  authorized  and  properly  executed by  Transferor  and,  assuming the due
authorization,  execution  and  delivery  hereof  by the other  parties  hereto,
constitutes the valid and binding obligation of Transferor,  enforceable against
Transferor in accordance with its terms.

                           (ii)  Conflicts.  The execution of and performance by
Transferor  of its  obligations  under  this  Agreement  does  not and  will not
conflict  with the  terms of  Transferor's  constituent  documents  and does not
breach or violate any  applicable  law, rule or  regulation of any  governmental
authority.  Subject to  obtaining  the required  consents  and  approvals by the
Lender,  there is no  agreement  to which  Transferor  is a party or  binding on
Transferor, which will be breached by or which is in conflict with the execution
of or performance by Transferor of its obligations  under this Agreement or with
the rights granted to Transferor hereunder.

                           (iii) Pending  Actions.  There is no action,  suit or
proceeding pending, or to Transferor's knowledge,  threatened against Transferor
or the Property which would, if adversely  determined,  have a material  adverse
effect on the financial condition or results of operations of Transferor.  There
is no action or proceeding  pending,  or to Transferor's  knowledge,  threatened
against Transferor which challenges or impairs  Transferor's ability to execute,
deliver or  perform  under  this  Agreement,  to  transfer  all of the  Property
hereunder or to consummate the transactions contemplated herein.

                  (b) Transferor's Property Representations and Warranties.

                           (i)  Contractors  and  Suppliers.   All  contractors,
subcontractors,  suppliers, architects, engineers and others that have performed
services  or  labor  or  supplied   material  in  connection  with  Transferor's
acquisition, development, ownership or management
                                        9
<PAGE>
of the Property have been, or will be in the ordinary  course of business,  paid
in full prior to Closing and all liens  arising  therefrom (or claims which with
the passage of time or notice or both,  could  mature into liens) have been,  or
will be in the ordinary  course of  business,  satisfied  and released  prior to
Closing.  On the Closing Date,  Transferor  shall provide the REIT a list of all
contracts that are not terminable  upon 30 days written notice without  penalty.
The Transferor shall not be required to pay any termination fees or penalties in
connection with contracts the REIT wishes to terminate, as such amounts shall be
the sole responsibility of the REIT.

                           (ii) Leases and Rent Roll. The Rent Roll delivered by
Transferor hereunder for its Real Property is true, accurate and complete in all
material respects.  Except as set forth in the Rent Roll or applicable Permitted
Exceptions,  there are no leases or occupancy agreements or rights of possession
affecting the Real Property.  Except as otherwise specifically and expressly set
forth in the Rent Roll for the Real  Property:  (1) no presently  effective rent
concessions have been given to any tenants; (2) no rent has been paid in advance
by any tenants  respecting a period  subsequent  to the Closing  (except for the
month in which the  Closing  occurs);  (3) no  tenants  have any  claim  against
Transferor for any deposits,  other than pursuant to the terms of its Lease with
respect to sums  specified as deposits in the Rent Roll; (4) no tenants have any
options or rights of first  refusal to extend or renew  their  Leases or to rent
additional  space  or  to  purchase  the  Property;  (5)  there  are  no  tenant
improvements  which are  incomplete  or which  have not been  fully  paid for by
Transferor except as otherwise specified in this Agreement; and (6) there are no
leasing fees or commissions due, nor will any become due, in connection with any
Lease or any renewal or extension of any Lease.  Except as set forth in the Rent
Roll, no  understanding  or agreement with any party exists as to payment of any
leasing or other fees or commissions  regarding future leases or as to procuring
of tenants  for the Real  Property.  To  Transferor's  knowledge,  no default or
breach exists on the part of any tenant.  Transferor has not received any notice
of any material default or breach on the part of the landlord under any Lease.

                           (iii)  Operating  and  Financial   Statements.   Each
Operating and Financial Statement for the Real Property shows all material items
of income and  expense  (operating  and  capital)  incurred in  connection  with
Transferor's  ownership,  operation and management of such Real Property for the
periods indicated and are true, correct and complete in all material respects.

                           (iv) Notice of Violations. To Transferor's knowledge,
Transferor has not received notice that the Property or the use thereof violates
any laws, rules and regulations of any federal, state, city or county government
or any agency, body or subdivision thereof having any jurisdiction over Property
that have not been resolved to the satisfaction of the issuer of the notice.

                           (v) Zoning,  Applicable Laws Governing  Operation and
Restrictions.  To Transferor's  knowledge,  neither the Property or Transferor's
current use or operation thereof
                                       10
<PAGE>
fails to  comply or is in  violation,  in any  material  respect,  with  current
applicable  laws,  regulations,  ordinances,  building  codes  and  rules of all
applicable municipal, local, state and federal jurisdictions, including, without
limitation,  zoning ordinances,  parking  requirements,  building codes and laws
governing access for handicapped  persons,  and with restrictions,  covenants or
similar agreements affecting such Property.

                           (vi)   Taxes   and   Assessments.   To   Transferor's
knowledge,  all taxes for the current  year and all prior years for the Property
which are due and payable have been paid,  except for  installments  due and not
yet  delinquent  and  supplemental  taxes  not yet  assessed,  and no taxes  are
delinquent.  All impact  fees or other  assessments,  fees or  charges,  however
denominated, which may constitute a lien or charge on the Property or which have
been assessed or charged as a result of any permit, license or approval obtained
for the Property have been paid in full, and there is not presently  pending any
such  assessment,  fees or charges of any nature with respect to the Property or
any  part  thereof,   nor  has  Transferor  received  any  notice  of  any  such
assessments,  fees or  charges  being  contemplated.  No areas  within  the Real
Property are subject to any  existing  improvement  districts,  except as may be
disclosed by the applicable Title Report and any amendments  thereto.  All taxes
with  respect to  Transferor  and the  ownership  and  operation of the Property

receipts,  net proceeds, ad valorem,  turnover,  personal property (tangible and
intangible),  sales, use, franchise, excise, value added, stamp, leasing, lease,
user, transfer,  fuel, excess profits,  occupational and interest  equalization,
windfall  profits,  severance  and  employees'  income  withholding  and  Social
Security  taxes  imposed by the United  States or any foreign  country or by any
state,  municipality,  subdivision or instrumentality of the United States or of
any foreign  country or by any other tax  authority,  including  all  applicable
penalties and interest (the "Other Taxes"), which are due and payable, have been
paid as  disclosed  on the  returns to the extent due.  Transferor  has duly and
timely  filed all tax  returns of every  nature  required to be filed by it with
respect to the Other  Taxes,  in every  jurisdiction  in which the same may have
been so required,  and has paid all Other Taxes disclosed on such returns to the
extent  due.  All Other Taxes of which  notice has been  received or which shall
accrue on or prior to the Closing Date have been paid to the extent due.

                           (vii) Hazardous Materials.  The environmental reports
for the Property delivered to the REIT by Transferor  constitute true,  accurate
and complete copies of all of the environmental  reports prepared for Transferor
for the  Property.  To  Transferor's  knowledge,  the  Real  Property  is not in
noncompliance or in violation of Environmental  Laws, except as disclosed in any

                           (viii)   Withholding   Obligation.   To  Transferor's
knowledge, the convey- ance to Heritage LP of the Property is not subject to any
federal,  state or local withholding obligation of Transferor under the tax laws

"bulk sales" or other similar laws.

                           (ix) Condemnation. No condemnation,  claims, actions,
suits  or  proceedings  relating  to  the  Real  Property  are  pending  or,  to
Transferor's knowledge, threatened.

                           (x) Insurance.  The schedule of all insurance carried
and the costs  thereof with respect to the Property  provided by  Transferor  is
true,  accurate and  complete.  Transferor  has not received any notice from any
insurance  company or board of fire  underwriters of any defects or inadequacies
in, on or about any of the Real  Property or any part or component  thereof that
would  adversely  affect  the  insurability  of the  Real  Property  or cause an
increase in the premiums  for the Property  that have not been cured or repaired
to the  satisfaction  of the party issuing the notice.  All  insurance  policies
insuring the Real Property are in full force and effect.

                           (xi) Ownership. Transferor is the owner and has title
to the Real Property free and clear of any and all claims,  taxes,  assessments,
reservations  in  patents,  easements,   rights-of-way,   encumbrances,   liens,
covenants,  conditions,  restrictions,  obligations and  liabilities  other than
those  specifically  set  forth  herein or in the Title  Report or  approved  in
writing as set forth above.

                           (xii) Flood Area.  Except as may be  disclosed on the
survey respecting the Real Property,  to Transferor's  knowledge,  no portion of
the Real  Property is within any flood plain area as  designated  by the maps of
the Federal Emergency Management Agency (FEMA maps) or any other governmental or
quasi-governmental flood control agency.

                           (xiii)  Future   Transfer   Obligations.   Except  as
disclosed in the Title Report for the Real  Property and the Grant of Reciprocal
Easements and Joint Development Agreement, there are no agreements,  commitments
or understandings by or between Transferor and any third party pursuant to which
Transferor  or its  successors-in-interest  are required to dedicate any part of
the Real Property or to grant any easement, water rights, rights-of-way, road or
license  for  ingress and egress or other use in respect to any part of the Real
Property.

                           (xiv)  Creditors.  There are no attachments,  levies,
executions,   assignments   for  the   benefit  of   creditors,   receiverships,
conservatorships  or voluntary  or  involuntary  proceedings  in  bankruptcy  or
pursuant  to any other  debtor or relief  laws  contemplated  by  Transferor  or
pending  in  any  current  judicial  or   administrative   proceedings   against
Transferor.

                           (xv) Loan Documents.  The Loan Documents delivered by
Transferor to the REIT constitute  true,  accurate and complete copies of all of
the  documents  and  instruments  in effect with  respect to the  Mortgage  Debt
applicable  to  Transferor  in all  material  respects.  The  Schedule  of  Loan
Documents  delivered to the REIT by Transferor is in all material respects true,
accurate and complete. Transferor has not received any notice that Transferor is
in default under such Loan  Documents,  nor to  Transferor's  knowledge does any
default or breach exist, nor any event or circumstance  that, with the giving of
notice, or passage
                                       12
<PAGE>
of time,  or both,  would  constitute  a  default  or  breach  under  such  Loan
Documents.  The unpaid principal  balance under the Loan Documents  delivered to
the REIT by Transferor  after taking into account the July 1997 mortgage payment
applicable to Transferor's Property is set forth in Schedule II attached hereto.

                           (xvi) Solvency. To Transferor's knowledge, Transferor
is, and at all times  during the period  beginning on the date hereof and ending
on and  including  the Closing Date will be,  solvent.  As used herein,  solvent
means with respect to an entity that such entity (i) does not have debts greater
than the fair value of such entity's assets; (ii) is paying and anticipates that
it will  continue to pay such  entity's  debts as they become due; and (iii) has
sufficient capital to run such entity's business.

                           (xvii) Brokers' Fees.  Except for CB Commercial,  who
shall be paid solely by Transferor, no real estate broker, salesperson or finder
has engaged by  Transferor  in  connection  with the  transactions  contemplated
hereby  that  may  result  in  claims  for  commissions  or fees  in  connection
therewith.

                           (xviii)   Full   Disclosure.   Transferor   has  made
available or  accessible  to the REIT all  material  documents,  files,  written
information,  books and  records  in  Transferor's  possession  or  control  and
relating to the Property.

                  (c) Transferor's Securities Representations.

                           (i) Investment  Purpose. In the event that Transferor
receives  LP Units,  Transferor  will  acquire  the LP Units for the  purpose of
transferring  such LP Units to its  partners who intend to hold the LP Units for
investment  and not with a view to or for  sale in  connection  with any  public
distribution thereof within the meaning of the Securities Act.

                           (ii) Sufficient Knowledge and Experience.  Transferor
has  sufficient  knowledge and  experience in financial and business  matters to
enable  it to  evaluate  the  merits  and risks of  investment  in the LP Units.
Transferor has the ability to bear the economic risk of acquiring the LP Units.

                           (iii)  Access  to  Information.  Transferor  has been
supplied  with,  or had access to,  information  to which a reasonable  investor
would attach  significance in making investment  decisions,  including,  but not
limited to, all publicly  available filings by the REIT under the Securities Act
and  the  Exchange  Act,  and  the  REIT's  annual  and  quarterly   reports  to
stockholders, any information with respect to Heritage LP's financial condition,
business and prospects,  and any other information Transferor has requested,  to
answer all of its inquiries  about Heritage LP and the REIT, and to enable it to
make its decision to acquire the LP Units.

                           (iv)  Restrictions  on  Transfer.  Transferor  hereby
acknowledges that neither the LP Units nor the REIT Stock for which LP Units may
be exchanged are registered
                                       13
<PAGE>
under the  Securities  Act or any  state  securities  laws and  cannot be resold
without registration thereunder or exemption therefrom.  Transferor agrees that,
other than the transfers  contemplated to its partners, it will not transfer all
or any portion of the LP Units or the underlying Shares unless such transfer has
been registered or is exempt from registration  under the Securities Act and any
applicable  state  securities laws. The LP Units contain a prominent legend with
respect to the  restrictions  on  transfer  under the  Securities  Act and under
applicable state securities laws.

                  (d) ERISA  Representation  and Warranty.  Transferor  holds no
"plan  assets,"  within the meaning of  Department  of Labor  regulations  at 29
C.F.R. section 2510.3- 101, of any employee benefit plan subject to the Employee
Retirement   Income  Security  Act  of  1974,  as  amended   ("ERISA")  and  the
transactions  contemplated  by  this  Agreement  are not  part of an  agreement,
arrangement  or  understanding  designed  to  benefit a party in  interest  with
respect  to  any  employee  benefit  plan  subject  to  ERISA  that  invests  in
Transferor.

                  The term  "to  Transferor's  knowledge"  as it is used in this
Section 4.1 shall mean that the  officers  and  directors  of MTP have no actual
conscious knowledge of facts inconsistent with the matters stated. In connection
with the foregoing representations,  Transferor has made no specific examination
of files or records,  nor has  Transferor  made inquiry of any other employee of
Transferor,  its advisor,  or any management  company engaged by Transferor.  No
constructive  knowledge  of any  matter  shall be imputed  to  Transferor  as to
matters not within the actual  conscious  knowledge of the above-named  persons,
and no  personal  liability  shall  attach  to such  persons  as a result of any
violation of any  representation or warranty.  A breach of a representation  set
forth in this Section 4 by Transferor  or MTP shall  constitute a failure of the
condition set forth in Section 7.1(a) hereof.

         4.2  Further  Representations  and  Warranties  of MTP.  As a  material
inducement to the REIT and Heritage LP to execute this  Agreement and consummate
the transactions contemplated hereunder, MTP represents and warrants to the REIT
and Heritage LP that as of the date hereof and as of the Closing Date:

the  legal  and  binding  obligation  of MTP and is  enforceable  against  it in
accordance with the terms of this Agreement.

                  (c)  Agreement  Not  in  Breach  of  Other  Instruments.   The
execution and delivery of this Agreement,  the  consummation of the transactions
hereby contemplated, and the fulfillment of the terms hereof, will not result in
the breach of any term or provision of, or
                                       14
<PAGE>
constitute a default under,  or conflict with, or cause the  acceleration of any
obligation  under, any agreement or other instrument of any description to which
Transferor  or MTP is a party or by which  Transferor  or MTP is  bound,  or any
judgment,   decree,  order,  or  award  of  any  court,  governmental  body,  or
arbitrator, or to the knowledge of MTP, any applicable law, rule or regulation.

         4.3 The REIT's Representations and Warranties. As a material inducement
to the MTP Parties to execute this  Agreement and  consummate  the  transactions
contemplated hereunder, the REIT represents and warrants to the MTP Parties that

duly organized, is validly existing as a corporation under the laws of its state
of  incorporation  and is in good standing in such state and, if  different,  is

validly  existing  under the laws of its  organization  and,  if  different,  is
qualified to do business in the  jurisdictions  in which the  property  owned by
such  subsidiary  or the business  conducted by such  subsidiary  requires  such
qualification.  The REIT has the full  corporate  right  and  authority  and has
obtained any and all consents  required  therefor to enter into this  Agreement.
The persons  signing this  Agreement on behalf of the REIT are  authorized to do
so. This  Agreement  and all of the documents to be delivered by the REIT at the
Closing have been or will be  authorized  and  properly  executed and do or will
constitute the valid and binding  obligations of the REIT,  enforceable  against
the REIT in accordance with their terms.

                           (ii)  Conflicts.  The execution of and performance by
the REIT under this  Agreement  does not and will not conflict  with the Amended
and  Restated  Articles  of  Incorporation  or  By-Laws of the REIT and does not
breach or violate any  applicable  law, rule or  regulation of any  governmental
authority.  There is no agreement to which the REIT is a party or, to the REIT's
knowledge, binding on the REIT which will be breached by or which is in conflict
with its execution of or performance of its obligations  under this Agreement or
with the rights granted to the REIT hereunder.

                           (iii) Pending  Actions.  There is no action,  suit or

any of its  properties,  which would, if adversely  determined,  have a material
adverse effect on the financial  condition or results of operations of the REIT.
There is no action or proceeding pending or, to the REIT's knowledge, threatened
against  the REIT which  challenges  or impairs  the REIT's  ability to execute,
deliver and perform under this Agreement.

                           (i)  Reserved  Shares.  From the  authorized  capital
stock of the REIT, a  sufficient  number of shares of REIT Stock shall have been
reserved  by the REIT at Closing  for  issuance  to  Transferor  Partners in the
Exchange  Offer and to  Transferor  upon  exchange  of the LP Units  therefor in
accordance with Articles One and Two of this Agreement.

                           (ii) REIT Common  Stock.  The REIT Stock to be issued

paid and  nonassessable  and will not be  subject to any  preemptive  or similar
right and,  subject to compliance  with the Securities Act and the Exchange Act,
will be eligible for listing on the American Stock Exchange.  On or prior to the
Closing Date, the REIT shall have caused the  effectiveness  of the Registration
Statement  under the Securities Act and under any  applicable  state  securities
laws  covering the resale of the shares of REIT Stock to be issued in accordance
with the Exchange Offer; provided,  however, in the event that this Agreement is
terminated by the REIT pursuant to Section  10.3(d) or Section  10.3(f)  herein,
the REIT shall be entitled  to the prompt  reimbursement  for all  out-of-pocket
costs  (including,  without  limitation,   attorneys'  fees,  filing  fees,  and
disbursements)  incurred  by the REIT in  connection  with its  preparation  and
filing of the Registration Statement and any amendments and supplements thereto.

                           (iii) Registration Statement and Prospectus. When the
Registration Statement becomes effective, (i) the Registration Statement and the
prospectus  included  therein  (the   "Prospectus"),   and  any  amendments  and
supplements  thereto,  will  contain all  statements  and  information  that are
required to be included  therein in accordance  with the  Securities Act and the
applicable rules and regulations of the Securities and Exchange  Commission (the
"Rules and  Regulations")  and will  comply in all  material  respects  with the
requirements  of the  Securities  Act and the  Rules and  Regulations;  and (ii)
neither the  Registration  Statement  nor the  Prospectus,  nor any amendment to
supplement thereto,  will include an untrue statement of a material fact or omit
to state a material fact required to be stated  therein or necessary to make the
statements  therein not misleading;  provided,  however,  that the REIT makes no
representations  and warranties as to  information  contained in or omitted from
the  Registration  Statement  or  Prospectus,  or any  amendment  or  supplement
thereto,  in reliance upon and in conformity with  information  furnished to the
REIT by Transferor or MTP specifically for use in preparation thereof.

                  (c)  Brokers'  Fees.  No real estate  broker,  salesperson  or
finder  has  been  engaged  by the  REIT in  connection  with  the  transactions
contemplated  hereby  that may  result  in  claims  for  commissions  or fees in
connection therewith.

                  The term "to the REIT's knowledge" as used in this Section 4.3
shall mean that the officers and directors of the REIT have no actual  conscious
knowledge of facts  inconsistent with the matters stated. In connection with the
foregoing representations, the REIT has made no specific examination of files or
records, nor has the REIT made inquiry of any other
                                       16
<PAGE>
employee of the REIT,  its advisor,  or any  management  company of the REIT. No
constructive  knowledge of any matter shall be imputed to the REIT as to matters
not within the actual  conscious  knowledge of the above-named  persons,  and no
personal  liability shall attach to such persons as a result of any violation of
any  representation or warranty.  A breach of a representation set forth in this
Section 4 by the REIT shall  constitute a failure of the  condition set forth in
Section 7.2(a).

         4.4  Heritage  LP's  Representations  and  Warranties.  As  a  material
inducement  to the MTP Parties to execute  this  Agreement  and  consummate  the
transactions contemplated hereunder,  Heritage LP represents and warrants to the
MTP Parties that as of the date hereof and as of the Closing Date:

                  (a) Partnership  Organization  and Authority.  Heritage LP has
been duly organized under the Delaware Revised Uniform Limited  Partnership Act,
is validly existing as a Delaware limited  partnership,  and is in good standing
in the State of Delaware.  [The Subsidiary  Partnership  will be duly organized,
validly  existing,  and in good standing in the state of its organization at the

qualified  to  do  business  and  in  good  standing  under  the  laws  of  each
jurisdiction  in which the  Property  owned or to be owned by Heritage LP or the
Subsidiary  Partnership or the business conducted or to be conducted by Heritage

the sole limited partner of the Subsidiary Partnership. Heritage LP has the full
right and authority and has obtained any and all consents  required  therefor to
enter into this  Agreement  and to  consummate  or cause to be  consummated  the
transactions  contemplated  herein. The persons signing this Agreement on behalf
of Heritage LP at the Closing have been  authorized to do so. This Agreement and
all of the  documents to be delivered by Heritage LP at the Closing have been or
will be authorized and properly executed and do or will constitute the valid and
binding   obligations  of  Heritage  LP,  enforceable  against  Heritage  LP  in
accordance with their terms.

                  (b)  Conflicts.  The  execution  of and  performance  of  this
Agreement does not and will not conflict with the  Partnership  Agreement or the
Certificate  of Limited  Partnership  of Heritage  LP.  There is no agreement to
which Heritage LP is a party or, to Heritage LP's knowledge, binding on Heritage
LP  which  will be  breached  by or is in  conflict  with  its  execution  of or
performance under this Agreement.

                  (c) Pending Actions.  There is no action or proceeding pending
or,  to  Heritage  LP's  knowledge,  threatened  against  Heritage  LP or any of
Heritage LP's properties,  which would, if adversely determined, have a material
adverse  effect on the financial  condition or results of operations of Heritage
LP. There is no action or  proceeding  pending or, to Heritage  LP's  knowledge,
threatened  against  Heritage LP which challenge or impair Heritage LP's ability

the actual  conscious  knowledge  of the  above-named  persons,  and no personal
liability  shall  attach to such  persons  as a result of any  violation  of any
representation  or  warranty.  A breach  of a  representation  set forth in this
Section 4 by Heritage LP shall  constitute a failure of the  condition set forth
in Section 7.2(a).

         4.5  Disclaimer  of  Warranty.  Except as  expressly  set forth in this
Agreement, the contribution of the Property to Heritage LP is made on an "AS IS"
basis. The REIT Parties  acknowledge that, except as expressly  provided in this
Agreement,   neither   Transferor   nor  any  of  its   agents   have  made  any

character  whatsoever,  express or implied, oral or written, with respect to the
Property or the suitability or fitness of the Property for any particular use or

                        OF REPRESENTATIONS AND WARRANTIES
                        ---------------------------------

                  (a) Preservation of Business.  The MTP Parties shall use their
best  efforts  to (i)  preserve  intact the  present  business  organization  of

                  (b) Actions With Respect to the Property Prior to Closing.

                           (i)  Transferor  agrees  that prior to the Closing it

existing  insurance  coverage,  perform  its  obligations  under all leases with
tenants,  Service Contracts and Loan Documents  applicable to the Real Property,

(except in the ordinary  course of business) or entering  into or modifying  any
contract or agreements  relating to the Real Property  which would be binding on
Heritage  LP or the REIT  after the  Closing.  The REIT  shall have the right to
approve,  such approval not to be unreasonably withheld or delayed, any material
new contracts or contract modifications which are proposed by Transferor.

                           (iii) Transferor may enter into new Leases and modify
existing Leases relating to the Real Property without the REIT's consent so long

with respect to the  applicable  property with such  exceptions as are typically
made in the ordinary course of business and are on  Transferor's  standard form,
subject to customary modifications thereto.

                           (iv) Transferor  shall notify the REIT of any matters
that may arise prior to the Closing that could have a material adverse effect on
the Property and become known to the  Transferor,  such as pending or threatened
litigation,  notices  of  violations  from  governmental  or  quasi-governmental
authorities or agencies,  tenant  defaults,  bankruptcies  or  insolvencies  and
asserted landlord defaults.

                           (v) Except with the prior written consent of the REIT

shall  not  accept  rents or  occupancy  payments  from any  tenant  at the Real
Property  for more than one month in advance  except in the  ordinary  course of
business.

                  (g) Truth of Representations  and Warranties.  None of the MTP

                              --------------------

         7.1  Conditions to REIT Parties  Obligation  to Close.  Notwithstanding
anything to the contrary herein, the REIT Parties  obligations at the Closing to
consummate  the  transactions   contemplated  hereunder  (including  the  REIT's
obligations  to  accept  for  payment  or pay  for  any  Transferor  Partnership
Interests  tendered by a Transferor  Partner and Heritage  LP's  obligations  to
consummate the Asset  Transfer)  shall be contingent on the  satisfaction of the
following  conditions at the Closing (or the waiver  thereof by each of the REIT
Parties in their sole and absolute discretion):

                  (a)   Accuracy  of   Representations   and   Warranties.   The
representations and warranties of Transferor  contained herein shall be true and
correct in all  material  respects at Closing as if made as of the Closing  Date
(however,  if a  particular  representation  or  warranty  shall be made only to
Transferor's  knowledge,  then the condition under this Section 7.1(a) shall not
be deemed to be  fulfilled  with  respect to such items unless the same would be
fulfilled if such limitation did not exist; provided, however, in the event that
Transferor  receives notice of a condition within 15 days of the Expiration Date
that would render a particular  representation  or warranty untrue or incorrect,
such Transferor shall be entitled 15 calendar days from such notice to cure such
condition and, if necessary, the Expiration Date shall be extended accordingly).

<PAGE>
                  (b) Absence of Action or  Proceeding.  No action or proceeding
by any  governmental  agency shall have been instituted or threatened that would
enjoin,  restrain or prohibit, or that could reasonably be expected to result in
substantial  damages in respect of the Property that in the reasonable  judgment
of the REIT Parties make it inadvisable to consummate such  transaction,  and no
court order shall have been issued in any action or proceeding instituted by any
person that enjoins, restrains or prohibits the consummation of the transactions
contemplated  by this Agreement with respect to Transferor and no proceeding for
such an order shall have been instituted that in the reasonable  judgment of the
REIT or Heritage LP is likely to result in the issuance of such an order.

                  (c) Transferor's Deliveries.  Transferor shall have delivered,
or caused  to be  delivered,  each of the items  specified  in  Section  8.3 and
Section 8.6 hereof that  Transferor is required to deliver and Transferor  shall
have performed in all material respects each of the other  obligations  required
to be performed by it under this Agreement.

                  (d) Compliance with Agreements and Covenants.  Each of the MTP
Parties  shall  have  performed  and  complied  with  each of their  agreements,
covenants,  and  obligations  to be  performed  on or prior to the Closing  Date
except those calling for performance after the Closing Date.

executed Letter of Transmittal for each Transferor Partner  participating in the

after receipt of each of the Title  Report,  the Survey,  the UCC Searches,  the
Loan  Documents  or  other  information  to be  provided  or made  available  by
Transferor (the "Due Diligence Period"), the REIT shall have performed or waived
its due  diligence  review and  examination  of such Title Report,  Survey,  UCC
Searches, Loan Documents and all information to be provided or made available by
Transferor  and shall have  determined in its sole and absolute  discretion,  to
proceed with the transactions  contemplated  under this Agreement.  It is agreed
that as of the date hereof,  the REIT has accepted the physical condition of the
Property as it exists on the date hereof in all  respects;  therefore,  the REIT
Parties  shall not be entitled to terminate  this  Agreement due to the physical
condition of the Property.  Except to the extent covered by a representation  or
warranty made in this Agreement,  a failure of the REIT to timely terminate this
Agreement  within the Due Diligence  Period shall be a deemed  acceptance by the
REIT of all aspects of the condition of the Property,  the Title Report, and the
Survey by the REIT.

                  (g) Approval of Title Report, Survey or UCC Searches. The REIT
shall have approved, in its sole discretion,  all matters disclosed by the Title
Report,  Survey or UCC Searches. If any person subsequently issues any amendment
to the Title Report, Survey or UCC Searches disclosing any additional matters or
changes in the legal  description  or additional  requirements  of the REIT, the
REIT shall have approved any such matter not disclosed by the
                                       23

Title Report,  Survey or UCC Searches or any previous amendment  thereto.  On or
before  fifteen (15) days after the Title  Company has delivered to the REIT the
Title Report,  Survey or UCC Searches (or any amendments thereto) the REIT shall
give written  notice of such approval or objection to  Transferor  and the Title
Company specifying in reasonable detail any matter to which the REIT objects. If
the REIT  delivers any notice of  objection to any matter,  within five (5) days
after receipt of such objection, Transferor shall notify in writing the REIT and
the Title Company whether Transferor is unable or unwilling to remove or satisfy
such matter objected to by the REIT on or before  Closing.  If the REIT fails to
notify  Transferor  and the Title Company at least twenty (20) days prior to the
Closing Date of any  objections to the Title  Report,  Survey or UCC Searches or
any  amendment  or  modification  thereto,  then the REIT shall be deemed to not
object  to any  matter  in the  Title  Report,  Survey  or UCC  Searches  or any
modification thereto.

REIT (i) an Owner's Policy of Title Insurance (the "Title Policy") issued by the

Policy to be delivered at Closing and shall  execute at Closing such  affidavits
and indemnities as may be appropriate  under  applicable facts and as reasonably
required  by the Title  Company in order for it to issue  such  above-referenced
Title Policy.

         8.9  Property  Closing  Costs.  All  transfer  fees or stamp  taxes and
recording  fees required to be paid to record the deeds and any loan  assignment
documents with respect to the Property  together with any  commissions set forth
in Schedule IV shall be paid by Transferor.  The costs of the Title Report,  the
Survey and the UCC Searches and the costs of recording any documents required to
satisfy or release Title Objections shall be paid one-half by the REIT on behalf
of  Heritage  LP and  one-half by the  Transferor  subject to the Title  Report,
Survey, or UCC search.  The premiums for the standard Title Policy shall be paid
one hundred percent (100%) by Transferor  immediately prior to the Closing.  The
cost of any additional endorsement or upgrades to the Title Policy shall be paid
one  hundred  percent  (100%) by the REIT.  Notwithstanding  the  foregoing,  in
connection  with the  transfer  of the  Property  and Smith  Summit  and Park On
Preston (collectively,  the "Other Properties"),  Transferor's obligation to pay
the  premiums  for the Title  Policy  shall be limited to the amount of premiums
that would be payable if the  Property  and the Other  Properties  were  insured
together in a single  title  policy,  and  Heritage LP shall pay the premiums in
excess of such amount;  provided,  however,  if the Lender or the lenders of the
mortgage debt to which the Other  Properties are subject require  separate title
policies  for the Property and each of the Other  Properties,  Transferor  shall
have the  obligation  to pay the full amount of the premiums  for such  separate
title policy for the  Property.  In no event shall the  Transferor be liable for
the payment of the title  premium  associated  with  amending the survey for the
Property.  Any  prepayment  fees or  premiums  or  assumption  fees or  costs in
connection  with the assumption or repayment of any Mortgage Debt by Heritage LP
shall be paid by the REIT. All costs and expenses  described in this Section 8.9
are herein called
                                       31
<PAGE>
the "Property  Closing  Costs." The parties  acknowledge  that certain  Property
Closing  Costs may not be paid at Closing  but will be paid in  ordinary  course
following the Closing.

         8.10  Prorations.  The items in this  Section  8.10 with respect to the
Real  Property  shall be  apportioned  or prorated  between the  Transferor  and
Heritage  LP as of the end of the day  preceding  the  Closing  Date in order to
determine the amount of the Proration with respect to such Property. If the Cash
Payment  considered  payable to  Transferor  pursuant  to Section  2.2(b) is not
received by the Title  Company  before  1:00 p.m.,  Dallas,  Texas time,  on the
Closing Date, the  prorations  shall be made as of the date in which the Closing
occurs (i.e.,  each Transferor  shall receive rents and pay expenses for the day
of Closing with respect to such  Transferor's  Property).  All prorations  other
than the  Dividend  Distribution  Offset set forth in Section  8.10(j)  shall be
based upon a fraction  determined by dividing the number of days elapsed through
the date of the  Closing by 365.  The  parties  shall  compute or  estimate  all
prorations  prior to the Closing Date, and Transferor  shall supply  Heritage LP
before the Closing satisfactory supporting evidence for all such adjustments:

                  (a) Taxes  and  Assessments.  General  real  estate  taxes and
assessments  imposed by governmental  authority ("Taxes") and any assessments by
private  covenant  constituting  a lien or charge on the Real  Property  for the
then-current  calendar year or other current tax period not yet due and payable,
together  with, if  applicable,  state and local taxes  thereon.  If the Closing
occurs  prior to the  receipt  of the tax bill  for the  Real  Property  for the
calendar year or other  applicable tax period for the Real Property in which the
Closing occurs,  Taxes for such calendar year or other applicable tax period for
the Real  Property  shall be prorated  based upon the most recent  ascertainable
assessed values and tax rates.

                  (b) Collected  Rent.  All collected rent and other income (and
any applicable state or local tax on rent) under Leases in effect at the Closing
but excluding  payments that may  constitute  rent but are provided for in other
subparagraphs of this Section 8.10. Transferor shall be charged with any rentals
collected by Transferor before the Closing, but applicable to any period of time
after such Closing. Any rent and other income delinquent as of the Closing shall
not be prorated.  Heritage LP shall use reasonable  efforts (which efforts shall
not require Heritage LP or the REIT to initiate any lawsuit) to collect any rent
delinquent  as of the  Closing,  and any rent  delinquent  as of the Closing but
collected  after the Closing shall be applied first to current rent  obligations
then to delinquent rent in inverse order of incurrence, with any amounts applied
to any period prior to the Closing remitted to Transferor. Heritage LP may treat
any rent received  after the 27th of any month as rent for the next month.  Once
the Closing has occurred,  Transferor  shall not have any right to seek by legal
action or otherwise  collection of any rents  delinquent for any period prior to
the Closing,  unless the tenant has vacated the premises  under the Lease before
the Closing and the Lease is not assigned to Heritage LP.

                  (c) Utilities.  To the extent such expenses are the obligation
of Transferor and not tenants under Leases,  utilities,  including water, sewer,
electric,  and gas,  based upon the last reading of meters prior to the Closing.
If the utility company will not issue separate bills,
                                       32
<PAGE>
Transferor's portion will be charged against Transferor and Heritage LP will pay
the entire bill after the  Closing.  If  Transferor  has paid any  utilities  in
advance in the ordinary course of business,  then  Transferor  shall be credited
for  Heritage  LP's  portion  of such  payment  at the  Closing.  The  amount of
deposits,  if any, with utility  companies that are  transferrable  and that are
assigned  by  Transferor  to  Heritage  LP at the  Closing  shall be credited to
Transferor.  The amount of any  deposits  with  utility  companies  that are not
transferable  and that are not  assigned  by  Transferor  to  Heritage LP at the
Closing shall remain the property of Transferor.

                  (d) Fees and Charges  Under Service  Contracts.  To the extent
such expenses are the  obligations of Transferor and not of a tenant's under its
Lease,  fees and charges under any Service  Contracts that are being assigned to
and  assumed by  Heritage LP at the Closing on the basis of the periods to which
such Service Contracts relate.

                  (e) Transferred  Debt.  Interest accrued through the day prior
to the Closing Date and not yet due and payable and any principal,  interest and
other  amounts due and payable at the Closing Date  pursuant to the  Transferred
Debt; provided, however, transfer fees due and payable to holders of Transferred
Debt shall be paid in accordance with Section 8.9 hereof.

                  (f)  Insurance.  Premiums or other fees payable in  connection
with any insurance  policies that are being  assigned to and assumed by Heritage
LP at the Closing.

                  (g) Other  Expenses.  All  other  liabilities  related  to the
ownership or operation of the Property  that  Heritage LP may agree to assume or
take subject to in writing.

                  (h) Contractors and Suppliers. Amounts payable to contractors,
subcontractors,  designers, suppliers, architects, engineers and others who have
performed  services  or  labor  or  supplied  material  in  connection  with the
Property.

                  (i) Leasing Commissions.  Leasing or other fees or commissions
payable in  connection  with any Lease or any renewal or extension of any Lease,
but only to the extent  that such fees or  commissions  have been  disclosed  to
Heritage  LP and the REIT on the Rent  Roll.  For the  avoidance  of doubt,  the
parties acknowledge that with respect to the majority of Leases, all commissions
due to brokers for the initial term of such Leases have been  previously paid by
the  Transferor  on a "cash out" basis and there will be no  proration  of those
commissions at Closing;  however, Heritage LP acknowledges that, as described on
the Rent Rolls,  commissions  for renewals and  extensions of such Leases may be
due  and  payable  in the  future  on a  "cash  out"  basis  at the  time of the
applicable tenant's exercise of a renewal or option to extend or may be payable,
for such extension or renewal, on a monthly basis.

                  (j) Dividend  Distribution  Offset.  An amount (the  "Dividend
Distribution Offset") equal to (i) the product of (A) the total number of shares
of  REIT  Stock  and  LP  Units  issued  in  connection  with  the  transactions
contemplated by this Agreement and (B) $.50 (the "Dividend Amount"),  multiplied
by (ii) the ratio of (A) the difference between the total number
                                       33
<PAGE>
of calendar  days during the quarter in which the Closing  occurs (the  "Closing
Quarter")  and the number of calendar  days during the Closing  Quarter prior to
the Closing  Date and (B) the total  number of calendar  days during the Closing
Quarter  shall be deposited in escrow by  Transferor on the Closing Date. On the
date of  distribution  of the  dividend  payment  for the Closing  Quarter  (the
"Dividend  Distribution  Date"),  the  Dividend  Distribution  Offset  shall  be
released  to the REIT;  provided,  however,  in the event that the REIT does not
issue a dividend in the Closing  Quarter,  the Dividend  Distribution  Offset as
calculated  with the Dividend  Amount shall be released to the Transferor on the
Dividend  Distribution  Date or in the event that the REIT  issues a dividend of
less than $.50 in the Closing Quarter (the "Reduced Dividend Amount"), a portion
of the  Dividend  Distribution  Offset  equal to the  amount  of the  difference
between (a) the Dividend  Distribution  Offset as  calculated  with the Dividend
Amount, and (b) the Dividend  Distribution Offset as calculated with the Reduced
Dividend Amount shall be released to Transferor and the remaining  amount of the
Dividend  Distribution  Offset  shall be  released  to the REIT on the  Dividend
Distribution Date.

         8.11  Tenant   Deposits.   All  tenant  deposits,   including   without
limitation,  refundable  security  deposits,  refundable  pet  deposits  and key
deposits,  and advance rental deposits (and interest  thereon if required by law
or contract to be earned  thereon)  shall be  transferred  to Heritage LP at the
Closing, and Heritage LP shall assume the obligations to refund such deposits to
such tenants in accordance with their respective Leases after Closing,  but only
to the extent the obligation to refund such deposits arises after Closing.

         8.12 Income and Sales  Taxes.  All  income,  sales,  gross  receipts or
compensation  taxes and similar  taxes and fees  imposed upon  Transferor  under
applicable local or state law shall be paid by Transferor at the Closing.

         8.13 Permit Fees.  Customary  fees payable with respect to the transfer
of permits and  licenses  assigned by  Transferor  to Heritage LP at the Closing
with the consent or approval,  if required,  of the issuer thereof shall be paid
by Heritage LP.

         8.14 Wages. Transferor shall pay the wages, employment taxes and fringe
benefits  applicable  thereto payable to employees,  if any, of Transferor as of
their discharge on the Closing Date.

         8.15 Escrow Accounts. The parties acknowledge that the Transferred Debt
to be  assumed  has  Escrow  Accounts.  Upon the  Closing  (a) if  requested  by
Transferor, Heritage LP shall reimburse Transferor for the amount Transferor has
deposited into the Escrow  Account with respect to the Real Property,  whereupon
Transferor  shall  assign to Heritage  LP, and Heritage LP shall have sole right
and ownership of, all funds in such Escrow Account; or (b) each Transferor shall
withdraw  all funds that it has  deposited  in each  Escrow  Account,  whereupon
Heritage LP shall make the appropriate deposits into the Escrow Account.

reason  of any  insured  or  uninsured  casualty  during  the  period  up to and
including  the Closing  Date shall be borne by  Transferor.  In the event of any
material  damage to or destruction  of the Real Property or any portion  thereof
(notice of which shall  promptly be given to the REIT by  Transferor),  the REIT
may, at its option by notice to Transferor  given within ten (10) days after the
REIT is  notified  of such  damage  or  destruction  (and the  Closing  shall be
extended,  if necessary  to give the REIT such 10-day  period to respond to such
notice) (i) elect to proceed under this  Agreement with respect to the Property,
in which  event  Transferor  shall,  at the  Closing,  assign to Heritage LP all
insurance  proceeds  (including rent loss insurance to the period from and after
the Closing Date) for the damage,  Heritage LP shall assume  responsibility  for
the repair of the Real  Property,  and Heritage LP shall receive a credit at the
Closing for any  uninsured  portion of the damage and any  deductible  under the
insurance policy;  or (ii) terminate this Agreement.  In the event of any damage
to or  destruction  of the Real Property or any portion  thereof is not material
(notice of which  shall  promptly be given to the REIT  Parties by  Transferor),
Transferor shall, at the Closing,  assign to Heritage LP all insurance  proceeds
(including  rent loss  insurance to the period from and after the Closing  Date)
for the damage, the REIT shall assume  responsibility for the repair of the Real
Property,  and  Heritage  LP shall  receive  a  credit  at the  Closing  for any
uninsured portion of the damage and any deductible under the insurance policy.

                  "Material damage" and "materially damaged" means, with respect
to the applicable Real Property,  damage for which the cost to repair reasonably
exceeds ten percent (10%) of such Property's Deemed Value.

         9.2  Condemnation.  In  the  event  of  any  threatened,  commenced  or
consummated proceedings in eminent domain,  including,  without limitation,  any
conveyance in lieu thereof  (notice of which shall promptly be given to the REIT
by Transferor) (a "Condemnation Proceeding"),  which would constitute a material
condemnation respecting Real Property, the REIT may, at its option, by notice to
Transferor  given within ten (10) days after the REIT is notified of such actual
or possible  proceedings  (and the Closing shall be extended,  if necessary,  to
give the REIT such 10-day period to respond to such notice) (i) elect to proceed
under this  Agreement  with respect to the Property,  in which event  Transferor
shall,  at the  Closing,  assign to  Heritage  LP its  entire  right,  title and
interest in and to any  condemnation  award, and Heritage LP shall have the sole
right prior to Closing  (subject  to  Transferor's  approval  which shall not be
unreasonably  withheld  or  delayed)  and after the  Closing  to  negotiate  and
otherwise  deal with the condemning  authorities in respect of such matters;  or
(ii) terminate this Agreement. In the event that a Condemnation Proceeding would
not constitute a material condemnation respecting the Real Property,  Transferor
shall,  at the  Closing,  assign to  Heritage  LP its  entire  right,  title and
interest in and to any  condemnation  award, and Heritage LP shall have the sole
right  prior to Closing  (subject  to  Transferor's  approval  that shall not be
unreasonably withheld or delayed)
                                       35
<PAGE>
and after the  Closing  to  negotiate  and  otherwise  deal with the  condemning
authorities with respect of such matters.

                  "Material   condemnation"  means  with  respect  to  the  Real
Property,  a taking of (i) more than ten percent (10%) of the land  constituting
the Real  Property,  (ii) more than ten  percent  (10%) of the  parking  for the
buildings  on the Real  Property  (unless  the same can, on the  remaining  Real
Property so affected, be replaced),  (iii) any part of the buildings on the Real
Property,  (iv) a means of access to the Real Property unless  alternative means
of access  exist  which in the REIT's  judgment  are  adequate to serve the Real
Property,  or (v)  materially  adversely  affect  the use or  value  of the Real
Property.

                  8.10  Prorations.  The items in this Section 8.10 with respect
         to the Real  Property  shall be  apportioned  or  prorated  between the
         Transferor  and  Heritage  LP as of the  end of the day  preceding  the
         Closing Date in order to  determine  the amount of the  Proration  with
         respect to such Property. If the Cash Payment considered payable to the
         Custodian  pursuant  to  Section  2.2(b) is not  received  by the Title
         Company before 1:00 p.m., Dallas,  Texas time, on the Closing Date, the
         prorations  shall be made as of the date in which  the  Closing  occurs
         (i.e., each Transferor shall receive rents and pay expenses for the day
         of Closing with respect to such Transferor's Property).  All prorations
         other  than the  Dividend  Distribution  Offset  set  forth in  Section
         8.10(j)  shall be based  upon a fraction  determined  by  dividing  the
         number of days  elapsed  through  the date of the  Closing by 365.  The
         parties shall compute or estimate all  prorations  prior to the Closing
         Date,  and  Transferor  shall  supply  Heritage  LP before the  Closing
         satisfactory supporting evidence for all such adjustments. In the event
         that  any of the  items  in this  Section  8.10  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.  The provisions of this Section 8.10 shall
         survive the Closing.

         12. The definition of REIT Stock Price as set forth in the Contribution
Agreement shall be amended and restated in its entirety to read as follows:

                  "REIT Stock Price" shall mean $22.25.

                                 --------------

         1.1      The Exchange Offer.

                  (a)  Offer to  Purchase.  Provided  that  nothing  shall  have
occurred  that  would  result  in a  failure  to  satisfy  any of the  terms  or
conditions set forth in Article 7 of this Agreement,  as promptly as practicable
following the execution of this Agreement,  the REIT shall commence the Exchange
Offer by delivering  the Exchange  Offer  Documents  (as defined  below) to each
Transferor Partner. Each Transferor Partner that is an Accredited Investor shall
have
                                        2
<PAGE>
the right to tender all or any part of Transferor Partnership Interests owned by
such  Transferor  Partner  (such  tendered  Transferor   Partnership   Interests
hereinafter  referred to as "Tendered  Interests")  by executing and  delivering
prior to the Commitment Date to MTP, as custodian (the "Custodian"), a Letter of
Transmittal  pursuant  to which MTP will make and  accept  deliveries  by and on
behalf of the  Transferor  Partners as provided  in the Custody  Agreement.  The
obligations  of the REIT to accept for  purchase  and to purchase  any  Tendered
Interests  tendered by the  Transferor  Partners of Transferor  shall be subject
only to the  conditions  set  forth in this  Agreement.  The REIT  shall  not be
entitled to accept for purchase or purchase the Tendered Interests unless all of
the conditions to the  consummation  of the  transactions  contemplated  in this
Agreement are satisfied or waived as provided herein.

                  (b) Purchase  Price.  Subject to the  conditions  set forth in
Article 7 of this  Agreement,  on the Closing Date, the Custodian  shall deliver
the  Letters  of  Transmittal  to the REIT,  and the REIT  shall  deliver to the
Custodian,  as agent for each  Transferor  Partner on whose behalf the Custodian
delivered a Letter of Transmittal,  a certificate  registered in such Transferor
Partner's  name for the number of shares of REIT Stock equal to (i) the Exchange
Value of all of the Transferor Partnership Interests tendered by such Transferor
Partner and  accepted for  purchase  divided by (ii) the REIT Stock  Price.  For
purposes of  determining  the number of shares of REIT Stock to be issued in the
Exchange Offer,  Transferor Partnership Interests held by one person in multiple
accounts shall be aggregated. The REIT Stock to be issued in accordance with the
Exchange  Offer  will  be  duly  authorized,  validly  issued,  fully  paid  and
nonassessable  and will not be subject to any  preemptive  or similar right and,
subject to  compliance  with the  Securities  Act and the Exchange  Act, will be
eligible for listing on the American Stock Exchange.  On or prior to the Closing
Date, the REIT shall have caused the  effectiveness of a registration  statement
(the "Registration Statement") under the Securities Act and under any applicable
state  securities  laws  covering  the  resale of the shares of REIT Stock to be
issued in accordance with the Exchange Offer.

                  (c) Exchange Offer Documents. As soon as practicable after the
Commitment Date, the REIT shall prepare the Registration  Statement covering the
resale of shares of REIT Stock to be offered in the Exchange  Offer,  which will
comply in all material  respects with the  provisions of applicable  federal and
state  securities laws, and will prepare the Letter of Transmittal and a Custody
Agreement  appointing MTP the Transferor  Partners' Custodian to make deliveries
for the  Transferor  Partners at the Closing (the  Registration  Statement,  the
Letters of Transmittal and the Custody Agreement,  together with any supplements
or  amendments  thereto,  are referred to herein  collectively  as the "Exchange
Offer Documents").  The REIT shall prepare and make all filings under applicable
state  Blue Sky Laws to  qualify  or exempt  from  qualification  the REIT Stock
offered pursuant to the Exchange Offer.

                  (d) Election to Tender Transferor Partnership  Interests.  The
election  of a  Transferor  Partner  to tender  all or a part of the  Transferor
Partnership  Interests  owned by the  Transferor  Partner  shall be made by such
Transferor  Partner's execution of a Letter of Transmittal and the return of the
Letter of Transmittal to the Custodian for delivery to the REIT
                                        3
<PAGE>
pursuant to the Custody  Agreement.  Following the Commitment Date the tender of
Transferor Partnership Interests shall be irrevocable.

                  (e) Consent to  Admission  of REIT as  Partner.  The Letter of
Transmittal  shall provide that each Transferor  Partner  tendering a Transferor
Partnership  Interest in  Transferor  consents to the admission of the REIT as a
substituted  limited  partner upon the purchase of such  Transferor  Partnership
Interest.  MTP, as general partner of Gentry Place, consents to the admission of
the REIT as a substituted  limited partner of Transferor as of the Closing Date.
Promptly  following the Closing  Date,  Transferor  shall file any  certificates
necessary to reflect the admission of the REIT as a substituted limited partner.

                  (f) Term.  The  Exchange  Offer  shall  remain  open until the
commitment  date,  which  shall be 5:00 p.m.,  Dallas,  Texas time on August 11,
1997, unless extended by the REIT and MTP (the "Commitment  Date"). The Exchange
Offer  shall  expire  on the  Expiration  Date.  If the  Exchange  Offer  is not
consummated  prior to the Expiration  Date, the Custodian  shall promptly return
the Letter of Transmittal and all other materials  delivered to the Custodian by
the Transferor  Partner  pursuant to this  Agreement to the Transferor  Partner.
Prior to the  Commitment  Date,  the REIT shall not amend or modify the terms of
the Exchange Offer without the prior consent of MTP. After the Commitment  Date,
the Exchange Offer shall not be amended or modified.

         1.2 Tender of MTP's Transferor  Partnership  Interests.  Upon the terms
and subject to the  conditions  set forth in this  Agreement,  on the Commitment
Date, MTP shall have the right to tender all or any part of its right to receive
all or a portion of distributions as a general partner in Transferor to the REIT
in exchange for shares of REIT Stock  pursuant to the Exchange Offer on the same
terms and subject to the same  conditions as set forth in Section 1.1 above.  At
the Closing,  the REIT shall accept for payment all  assignments of the right to
receive distributions as a general partner tendered by MTP in Transferor. If the
tender of the right to receive general partner  distributions  is accepted,  the
REIT shall acquire all right,  title and interest to all  distributions  made by
Transferor  with  respect to the  interest  acquired,  but the REIT shall not be
substituted  as a general  partner.  MTP shall remain as the general  partner of
Transferor.

         1.3 Internal Revenue Code Section 754 Election. Unless Transferor has a
valid  election  in  place  pursuant  to  Internal  Revenue  Code  Section  754,
Transferor  hereby agrees to make such an election  effective  for  Transferor's
taxable year in which the Exchange Offer is consummated.

         2.1 The Asset Transfer.  Provided that nothing shall have occurred that
would result in a failure to satisfy any of the terms or conditions set forth in
this Agreement,  immediately  following the  transactions set forth in Article 1
hereof,  the REIT and Transferor shall  consummate the Asset Transfer.  The REIT
and  Heritage  SGP shall make a cash  capital  contribution  to  Heritage  LP in
accordance  with Section  2.2(a) hereof and will continue to be the sole general
partners of Heritage LP.  Transferor shall contribute and convey the Property to
Heritage  LP in  exchange  for LP Units and cash as set forth in Section  2.2(b)
hereof.  Pursuant to the terms of the Partnership Agreement,  the LP Units shall
be  exchangeable  for REIT Stock at any time following the first  anniversary of
the Closing Date.  Pursuant to the Asset Transfer  Registration  Agreement,  the
REIT shall agree to register for resale under federal securities laws the shares
of REIT Stock to be issued upon conversion of the LP Units.

         2.2      Contribution of Property to Heritage LP.

                  (a)  Capital  Contributions.  On the Closing  Date,  the REIT,
Heritage SGP and Transferor  shall make the following  capital  contributions to
Heritage LP:

                           (i) The  REIT  and  Heritage  SGP  shall  make a cash
capital   contribution   equal  on  an  aggregate  basis  to  the  REIT  Capital
Contribution which shall be the sum of:

                                    (A) that portion of the Mortgage  Debt to be
repaid or  cancelled  by  Heritage  LP in  accordance  with  Section  2.3 hereof
including, without limitation, any prepayment fees or premiums,  assumption fees
and other costs associated therewith, plus

                                    (B)  the  amount  required  to  satisfy  any
monetary liens which the REIT elects to satisfy pursuant to Section 2.3(d), plus

                                    (C) the Property  Closing  Costs paid and to
be paid by Heritage LP or the REIT  pursuant to Section 8.9,  plus or minus,  as
appropriate

                                    (D) the Prorations, plus

                                    (E) all costs and  expenses  incurred and to
be incurred by Heritage  LP, the REIT or Heritage SGP (on behalf of Heritage LP)
in the performance of its due diligence hereunder, plus

                                    (F) any  amounts  required  to  satisfy  the
obligations  of the  REIT or  Heritage  SGP to  make  capital  contributions  to
Heritage  LP  pursuant  to  Section  4.1.2 or Section  4.1.6 of the  Partnership
Agreement, and plus
                                        5
<PAGE>
                                    (G) cash in the  amount of the Cash  Payment
(as defined herein).


                           (ii)  Transferor  shall  contribute  and  convey  the
Property owned by Transferor to Heritage LP as hereinafter provided subject only
to the Transferred Debt as described in Section 2.3 hereof.

                           (iii) Notwithstanding the foregoing,  if, taking into
consideration  the proposed  contributions  to the capital of Heritage LP by the
REIT,  Heritage SGP, and  Transferor in accordance  with Section  2.2(a) hereof,
Heritage LP would not be consolidated with the REIT for financial accounting and
reporting purposes because the respective  Partnership  Interests of the REIT or
Heritage  SGP in  Heritage LP is  insufficient,  then at the Closing the REIT or
Heritage SGP may contribute  cash to Heritage LP in exchange for an amount of GP
Units equal to such cash contribution divided by the REIT Stock Price. Such cash
will be contributed in the minimum amount sufficient to permit Heritage LP to be
consolidated with the REIT for financial accounting and reporting purposes.

                  (b)  Distribution  of Cash and LP Units.  In exchange  for the
capital  contribution  made by  Transferor  provided in Section  2.2(a)  hereof,
Heritage LP shall distribute the following on the Closing Date:

                           (i) Cash Payment.  At the Closing,  Transferor  shall
receive by wire transfer an amount (the "Cash  Payment") equal to the sum of (1)
the Cash  Allocation set forth on Schedule V attached  hereto and (2) such other
escrowed amounts held by Lender including,  but not limited to, taxes, insurance
and such  other  reserves  held by Lender on  Transferor's  behalf if elected by
Transferor pursuant to Section 8.15(a) herein, less the Earnest Deposit.

                           (ii) LP Units. At the Closing, Transferor, or certain
partners of Transferor designated by Transferor on Schedule VIII attached hereto
as updated  pursuant to Section  6.2(a)  hereof,  shall  collectively  receive a
number  of LP  Units  that  shall be equal  to (A) the  difference  between  the
Exchange  Value  attributable  to  Transferor  and the Cash Payment  pursuant to
clause (i), divided by (B) the REIT Stock Price.

                  (c) Distribution of GP Units. In exchange for the REIT Capital
Contribution  provided in Section 2.2(a) hereof,  Heritage LP shall issue on the
Closing  Date to the REIT and  Heritage  SGP a number of GP Units  (rounded to a
whole unit)  equal to the REIT  Capital  Contribution  divided by the REIT Stock
Price  allocated  between  them on a pro rata basis based upon their  respective
contributions.

         2.3      Assumption of Mortgage Debt.

                  (a)  Mortgage  Debt.  The  REIT,  Heritage  LP and  Transferor
acknowledge and agree that the Property is subject to the Mortgage Debt from the
lender (the "Lender") as
                                        6
<PAGE>
described  on Schedule II attached  hereto.  The  Property  shall be acquired by
Heritage  LP  subject to the  Mortgage  Debt,  provided  that the Lender of such
Mortgage Debt shall execute a consent,  estoppel letter, transfer agreement, and
modification  with  respect  to such  Mortgage  Debt as shall be  acceptable  to
Heritage  LP,  acting  reasonably;  provided,  however,  the Lender  will not be
required to amend any of the  material  legal or business  terms of the Mortgage
Debt.

                  (b)  Lender  Consent.  From  and  after  the date  hereof  and
continuing for 60 days  thereafter (the "Lender  Consent  Period"),  the parties
shall  proceed  in good  faith and with due  diligence  to attempt to secure any
lender consent and estoppel letter from the Lender and to negotiate any transfer
agreement  or  modifications  to the Loan  Documents in order for Heritage LP to
acquire the Property  subject to such Mortgage Debt.  Heritage LP agrees that it
shall accept the Property subject to the Mortgage Debt, provided that the Lender
agrees that such Mortgage Debt shall be  non-recourse to Heritage LP on the same
terms that such Mortgage Debt is currently  non-recourse  to Transferor  and the
Lender executes the agreements contemplated by Section 2.3(a). Any Mortgage Debt
to which the Property is subject upon transfer to Heritage LP is herein referred
to as "Transferred Debt."

                  (c) Refinancing of Mortgage Debt. In the event that the Lender
does not agree to the transfer of the Mortgage Debt as  contemplated  by Section
2.3(a) and Section 2.3(b), or if for any reason Heritage LP is unable to acquire
the Property  subject to the  Mortgage  Debt within the Lender  Consent  Period,
Heritage  LP shall  have the right to (i)  refinance  all or a  portion  of such
Mortgage  Debt  on  terms  it  determines  to be  acceptable  to it in its  sole
discretion;  (ii) pay all or any portion of such Mortgage Debt from the proceeds
of the REIT Capital  Contribution;  or (iii)  terminate  this  Agreement,  which
rights shall be exercised within the Lender Consent Period.

                  (d)  Indebtedness  Other Than Mortgage Debt.  Transferor shall
satisfy all pecuniary  encumbrances  (other than the Mortgage Debt) or otherwise
have all such  encumbrances  removed as liens  against the Property on or before
the Closing at its own expense.  Transferor shall not place any consensual lien,
encumbrance or easement against the Property  following the date of execution of
this Agreement  without the prior written  consent of the REIT, such consent not
to be unreasonably withheld or delayed. If Transferor fails to satisfy or remove
any  monetary  lien on or prior to  Closing,  the REIT may  proceed  to retain a
portion of the  Exchange  Value  equal to the amount of the  monetary  lien (the
"Holdback  Amount") and reduce the Exchange  Value of the Property  accordingly.
The  Holdback  Amount  shall be paid to  Transferor  at such time as  Transferor
extinguishes  such  monetary  lien.  In  the  event  that  Transferor  does  not
extinguish  such  monetary  lien within 120 days of the Closing  Date,  the REIT
shall apply the Holdback Amount to satisfy the monetary lien.  Transferor  shall
be required to deposit any additional  funds at Closing to satisfy any remaining
monetary liens against the Property.

         2.4 Earnest Money Deposit. Within five (5) days following the Execution
Date,  the REIT shall  deposit  $50,000 in escrow  with the Title  Company  (the
"Earnest Deposit") on
                                        7
<PAGE>
account of the REIT Capital Contribution. The Earnest Deposit shall be placed in
an  interest-bearing  account.  At the  Closing,  the Earnest  Deposit  shall be
applied against the Cash Payment.  In the event this Agreement is terminated for
any reason other than as a result of a termination  pursuant to Section 10.3(c),
the Earnest Deposit  required by this Section 2.4 shall be returned to the REIT.
In the event this  Agreement is  terminated  by  Transferor  pursuant to Section
10.3(c),  the Earnest Deposit  required by this Section 2.4 shall be paid to MTP
on behalf of Transferor.

                         REPRESENTATIONS AND WARRANTIES
                         ------------------------------

         4.1 Transferor Representations and Warranties. As a material inducement
to the REIT  Parties  to  execute  this  Agreement  and to the REIT  Parties  to
consummate the transactions  contemplated hereunder,  Transferor and MTP jointly
and  severally  represent and warrant to the REIT Parties with respect to itself
and the Property, that as of the date hereof and as of the Closing Date:

                  (a) Transferor Organizational Representations and Warranties.

                           (i) Organization  and Authority.  Transferor has been
duly  organized and is validly  existing and in good standing  under the laws of
its jurisdiction of organization and, if different,  is qualified to do business
and in good  standing in the state in which the Property is located.  Transferor
has the full right and authority to enter into this  Agreement.  Transferor  has
the full and right authority to transfer the Property and to consummate or cause
to be consummated the transactions  contemplated herein. This Agreement has been
duly  authorized  and  properly  executed by  Transferor  and,  assuming the due
authorization,  execution  and  delivery  hereof  by the other  parties  hereto,
constitutes the valid and binding obligation of Transferor,  enforceable against
Transferor in accordance with its terms.

                           (ii)  Conflicts.  The execution of and performance by
Transferor  of its  obligations  under  this  Agreement  does  not and  will not
conflict  with the  terms of  Transferor's  constituent  documents  and does not
breach or violate any  applicable  law, rule or  regulation of any  governmental
authority.  Subject to  obtaining  the required  consents  and  approvals by the
Lender,  there is no  agreement  to which  Transferor  is a party or  binding on
Transferor, which will be breached by or which is in conflict with the execution
of or performance by Transferor of its obligations  under this Agreement or with
the rights granted to Transferor hereunder.

                           (iii) Pending  Actions.  There is no action,  suit or
proceeding pending, or to Transferor's knowledge,  threatened against Transferor
or the Property which would, if adversely  determined,  have a material  adverse
effect on the financial condition or results of operations of Transferor.  There
is no action or proceeding  pending,  or to Transferor's  knowledge,  threatened
against Transferor which challenges or impairs  Transferor's ability to execute,
deliver or  perform  under  this  Agreement,  to  transfer  all of the  Property
hereunder or to consummate the transactions contemplated herein.

                  (b) Transferor's Property Representations and Warranties.

                           (i)  Contractors  and  Suppliers.   All  contractors,
subcontractors,  suppliers, architects, engineers and others that have performed
services  or  labor  or  supplied   material  in  connection  with  Transferor's
acquisition,  development, ownership or management of the Property have been, or
will be in the ordinary  course of  business,  paid in full prior to Closing and
all liens arising  therefrom (or claims which with the passage of time or notice
or both,  could mature into liens) have been, or will be in the ordinary  course
of business,  satisfied  and  released  prior to Closing.  On the Closing  Date,
Transferor  shall  provide  the  REIT  a list  of all  contracts  that  are  not
terminable upon 30 days written notice without penalty. The Transferor shall not
be  required  to pay  any  termination  fees or  penalties  in  connection  with
contracts  the REIT  wishes  to  terminate,  as such  amounts  shall be the sole
responsibility of the REIT.  Notwithstanding  the foregoing  statements,  Gentry
Place agrees to negotiate on the REIT's behalf for the  termination/cancellation
of an existing  security  monitoring  agreement between Gentry Place and Network
Multi-Family  Security  Corporation,  with such  termination  to be effective on
August 1, 1998. The REIT agrees and Gentry Place acknowledges that the REIT will
bear the cost of $160,000,  as a fee to affect the  termination of said contract
(the "Buyout Amount"). The REIT agrees and Gentry Place acknowledges that Gentry
Place will (a) be entitled to any savings  obtained if the Buyout Amount is less
than $160,000,  and (b) bear the  responsibility for any amount in excess of the
Buyout  Amount for Merit Place  Apartments.  Such amount in excess of the Buyout
Amount for Merit Place  Apartments  shall be credited to the REIT with regard to
Transferor  at Closing  and such  amount  less than the Buyout  Amount  shall be
credited to Transferor at Closing.

                           (ii) Leases and Rent Roll. The Rent Roll delivered by
Transferor hereunder for its Real Property is true, accurate and complete in all
material respects.  Except as set forth in the Rent Roll or applicable Permitted
Exceptions,  there are no leases or occupancy agreements or rights of possession
affecting the Real Property.  Except as otherwise specifically and expressly set
forth in the Rent Roll for the Real  Property:  (1) no presently  effective rent
concessions have been given to any tenants; (2) no rent has been paid in advance
by any tenants  respecting a period  subsequent  to the Closing  (except for the
month in which the  Closing  occurs);  (3) no  tenants  have any  claim  against
Transferor for any deposits,  other than pursuant to the terms of its Lease with
respect to sums  specified as deposits in the Rent Roll; (4) no tenants have any
options or rights of first  refusal to extend or renew  their  Leases or to rent
additional  space  or  to  purchase  the  Property;  (5)  there  are  no  tenant
improvements  which are  incomplete  or which  have not been  fully  paid for by
Transferor except as otherwise specified in this Agreement; and (6) there are no
leasing fees or commissions due, nor will any become due, in connection with any
Lease or any renewal or extension of any Lease.  Except as set forth in the Rent
Roll, no  understanding  or agreement with any party exists as to payment of any
leasing or other fees or commissions  regarding future leases or as to procuring
of tenants  for the Real  Property.  To  Transferor's  knowledge,  no default or
breach exists on the part of any tenant.  Transferor has not received any notice
of any material default or breach on the part of the landlord under any Lease.

                           (iii)  Operating  and  Financial   Statements.   Each
Operating and Financial Statement for the Real Property shows all material items
of income and  expense  (operating  and  capital)  incurred in  connection  with
Transferor's  ownership,  operation and management of such Real Property for the
periods indicated and are true, correct and complete in all material respects.

                           (iv) Notice of Violations. To Transferor's knowledge,
Transferor has not received notice that the Property or the use thereof violates
any laws, rules and regulations of any federal, state, city or county government
or any agency, body or subdivision thereof having any jurisdiction over Property
that have not been resolved to the satisfaction of the issuer of the notice.

                           (v) Zoning,  Applicable Laws Governing  Operation and
Restrictions.  To Transferor's  knowledge,  neither the Property or Transferor's
current use or  operation  thereof  fails to comply or is in  violation,  in any
material  respect,  with  current  applicable  laws,  regulations,   ordinances,
building codes and rules of all applicable  municipal,  local, state and federal
jurisdictions,   including,  without  limitation,  zoning  ordinances,   parking
requirements,  building codes and laws governing access for handicapped persons,
and with restrictions, covenants or similar agreements affecting such Property.

                           (vi)   Taxes   and   Assessments.   To   Transferor's
knowledge,  all taxes for the current  year and all prior years for the Property
which are due and payable have been paid,  except for  installments  due and not
yet  delinquent  and  supplemental  taxes  not yet  assessed,  and no taxes  are
delinquent.  All impact  fees or other  assessments,  fees or  charges,  however
denominated, which may constitute a lien or charge on the Property or which have
been assessed or charged as a result of any permit, license or approval obtained
for the Property have been paid in full, and there is not presently  pending any
such  assessment,  fees or charges of any nature with respect to the Property or
any  part  thereof,   nor  has  Transferor  received  any  notice  of  any  such
assessments,  fees or  charges  being  contemplated.  No areas  within  the Real
Property are subject to any  existing  improvement  districts,  except as may be
disclosed by the applicable Title Report and any amendments  thereto.  All taxes
with  respect to  Transferor  and the  ownership  and  operation of the Property

receipts,  net proceeds, ad valorem,  turnover,  personal property (tangible and
intangible),  sales, use, franchise, excise, value added, stamp, leasing, lease,

windfall  profits,  severance  and  employees'  income  withholding  and  Social
Security  taxes  imposed by the United  States or any foreign  country or by any
state,  municipality,  subdivision or instrumentality of the United States or of
any foreign  country or by any other tax  authority,  including  all  applicable
penalties and interest (the "Other Taxes"), which are due and payable, have been
paid as  disclosed  on the  returns to the extent due.  Transferor  has duly and
timely  filed all tax  returns of every  nature  required to be filed by it with
respect to the Other  Taxes,  in every  jurisdiction  in which the same may have
been so required,  and has paid all Other Taxes disclosed on such returns to the
extent
                                       11

due. All Other Taxes of which notice has been  received or which shall accrue on

                           (vii) Hazardous Materials.  The environmental reports
for the Property delivered to the REIT by Transferor  constitute true,  accurate
and complete copies of all of the environmental  reports prepared for Transferor
for the  Property.  To  Transferor's  knowledge,  the  Real  Property  is not in
noncompliance or in violation of Environmental  Laws, except as disclosed in any
environmental reports in Transferor's possession that have been delivered to the
REIT.

                           (viii)   Withholding   Obligation.   To  Transferor's
knowledge, the convey- ance to Heritage LP of the Property is not subject to any
federal,  state or local withholding obligation of Transferor under the tax laws
applicable  to Transferor or the Property,  including  without  limitation,  any
"bulk sales" or other similar laws.

                           (ix) Condemnation. No condemnation,  claims, actions,
suits  or  proceedings  relating  to  the  Real  Property  are  pending  or,  to
Transferor's knowledge, threatened.

                           (x) Insurance.  The schedule of all insurance carried
and the costs  thereof with respect to the Property  provided by  Transferor  is
true,  accurate and  complete.  Transferor  has not received any notice from any
insurance  company or board of fire  underwriters of any defects or inadequacies
in, on or about any of the Real  Property or any part or component  thereof that
would  adversely  affect  the  insurability  of the  Real  Property  or cause an
increase in the premiums  for the Property  that have not been cured or repaired
to the  satisfaction  of the party issuing the notice.  All  insurance  policies
insuring the Real Property are in full force and effect.

                           (xi) Ownership. Transferor is the owner and has title
to the Real Property free and clear of any and all claims,  taxes,  assessments,
reservations  in  patents,  easements,   rights-of-way,   encumbrances,   liens,
covenants,  conditions,  restrictions,  obligations and  liabilities  other than

writing as set forth above.

                           (xii) Flood Area.  Except as may be  disclosed on the
survey respecting the Real Property,  to Transferor's  knowledge,  no portion of
the Real  Property is within any flood plain area as  designated  by the maps of
the Federal Emergency Management Agency (FEMA maps) or any other governmental or
quasi-governmental flood control agency.

                           (xiii)  Future   Transfer   Obligations.   Except  as
disclosed in the Title Report for the Real  Property,  there are no  agreements,
commitments  or  understandings  by or between  Transferor  and any third  party
pursuant  to which  Transferor  or its  successors-in-interest  are  required to
dedicate any part of the Real Property or to grant any easement, water rights,
                                       12
<PAGE>
rights-of-way, road or license for ingress and egress or other use in respect to
any part of the Real Property.

                           (xiv)  Creditors.  There are no attachments,  levies,
executions,   assignments   for  the   benefit  of   creditors,   receiverships,
conservatorships  or voluntary  or  involuntary  proceedings  in  bankruptcy  or
pursuant  to any other  debtor or relief  laws  contemplated  by  Transferor  or
pending  in  any  current  judicial  or   administrative   proceedings   against
Transferor.

                           (xv) Loan Documents.  The Loan Documents delivered by
Transferor to the REIT constitute  true,  accurate and complete copies of all of
the  documents  and  instruments  in effect with  respect to the  Mortgage  Debt
applicable  to  Transferor  in all  material  respects.  The  Schedule  of  Loan
Documents  delivered to the REIT by Transferor is in all material respects true,
accurate and complete. Transferor has not received any notice that Transferor is
in default under such Loan  Documents,  nor to  Transferor's  knowledge does any
default or breach exist, nor any event or circumstance  that, with the giving of
notice,  or passage of time, or both, would constitute a default or breach under
such Loan  Documents.  The unpaid  principal  balance  under the Loan  Documents
delivered  to the REIT by  Transferor  after  taking into  account the July 1997
mortgage payment applicable to Transferor's Property is set forth in Schedule II
attached hereto.

                           (xvi) Solvency. To Transferor's knowledge, Transferor
is, and at all times  during the period  beginning on the date hereof and ending
on and  including  the Closing Date will be,  solvent.  As used herein,  solvent
means with respect to an entity that such entity (i) does not have debts greater
than the fair value of such entity's assets; (ii) is paying and anticipates that
it will  continue to pay such  entity's  debts as they become due; and (iii) has
sufficient capital to run such entity's business.

                           (xvii) Brokers' Fees.  Except for CB Commercial,  who
shall be paid solely by Transferor, no real estate broker, salesperson or finder
has engaged by  Transferor  in  connection  with the  transactions  contemplated
hereby  that  may  result  in  claims  for  commissions  or fees  in  connection
therewith.

                           (xviii)   Full   Disclosure.   Transferor   has  made
available or  accessible  to the REIT all  material  documents,  files,  written
information,  books and  records  in  Transferor's  possession  or  control  and
relating to the Property.

                  (c) Transferor's Securities Representations.

                           (i) Investment  Purpose. In the event that Transferor
receives  LP Units,  Transferor  will  acquire  the LP Units for the  purpose of
transferring  such LP Units to its  partners who intend to hold the LP Units for
investment  and not with a view to or for  sale in  connection  with any  public
distribution thereof within the meaning of the Securities Act.
                                       13
<PAGE>
                           (ii) Sufficient Knowledge and Experience.  Transferor
has  sufficient  knowledge and  experience in financial and business  matters to
enable  it to  evaluate  the  merits  and risks of  investment  in the LP Units.
Transferor has the ability to bear the economic risk of acquiring the LP Units.

                           (iii)  Access  to  Information.  Transferor  has been
supplied  with,  or had access to,  information  to which a reasonable  investor
would attach  significance in making investment  decisions,  including,  but not
limited to, all publicly  available filings by the REIT under the Securities Act
and  the  Exchange  Act,  and  the  REIT's  annual  and  quarterly   reports  to
stockholders, any information with respect to Heritage LP's financial condition,
business and prospects,  and any other information Transferor has requested,  to
answer all of its inquiries  about Heritage LP and the REIT, and to enable it to
make its decision to acquire the LP Units.

                           (iv)  Restrictions  on  Transfer.  Transferor  hereby
acknowledges that neither the LP Units nor the REIT Stock for which LP Units may
be exchanged are registered  under the  Securities  Act or any state  securities
laws  and  cannot  be  resold  without  registration   thereunder  or  exemption
therefrom.  Transferor agrees that, other than the transfers contemplated to its
partners,  it will  not  transfer  all or any  portion  of the LP  Units  or the
underlying  Shares  unless such  transfer has been  registered or is exempt from
registration  under the Securities Act and any applicable state securities laws.
The LP Units  contain a prominent  legend with  respect to the  restrictions  on
transfer under the Securities Act and under applicable state securities laws.

                  (d) ERISA  Representation  and Warranty.  Transferor  holds no
"plan  assets,"  within the meaning of  Department  of Labor  regulations  at 29
C.F.R. section 2510.3- 101, of any employee benefit plan subject to the Employee
Retirement   Income  Security  Act  of  1974,  as  amended   ("ERISA")  and  the
transactions  contemplated  by  this  Agreement  are not  part of an  agreement,
arrangement  or  understanding  designed  to  benefit a party in  interest  with
respect  to  any  employee  benefit  plan  subject  to  ERISA  that  invests  in
Transferor.

                  The term  "to  Transferor's  knowledge"  as it is used in this
Section 4.1 shall mean that the  officers  and  directors  of MTP have no actual
conscious knowledge of facts inconsistent with the matters stated. In connection
with the foregoing representations,  Transferor has made no specific examination
of files or records,  nor has  Transferor  made inquiry of any other employee of
Transferor,  its advisor,  or any management  company engaged by Transferor.  No
constructive  knowledge  of any  matter  shall be imputed  to  Transferor  as to
matters not within the actual  conscious  knowledge of the above-named  persons,
and no  personal  liability  shall  attach  to such  persons  as a result of any
violation of any  representation or warranty.  A breach of a representation  set
forth in this Section 4 by Transferor  or MTP shall  constitute a failure of the
condition set forth in Section 7.1(a) hereof.

         4.2  Further  Representations  and  Warranties  of MTP.  As a  material
inducement to the REIT and Heritage LP to execute this  Agreement and consummate
the transactions
                                       14

and consents to the transactions contemplated herein and represents and warrants
that it has approved this Agreement and the transactions hereby contemplated.

                  (b) Power of MTP to Execute Agreement.  MTP has full power and
authority to execute, deliver, and perform this Agreement, and this Agreement is
the  legal  and  binding  obligation  of MTP and is  enforceable  against  it in
accordance with the terms of this Agreement.

                  (c)  Agreement  Not  in  Breach  of  Other  Instruments.   The
execution and delivery of this Agreement,  the  consummation of the transactions
hereby contemplated, and the fulfillment of the terms hereof, will not result in
the  breach of any term or  provision  of, or  constitute  a default  under,  or
conflict with, or cause the acceleration of any obligation  under, any agreement
or other  instrument of any description to which Transferor or MTP is a party or
by which Transferor or MTP is bound, or any judgment, decree, order, or award of
any court,  governmental  body, or  arbitrator,  or to the knowledge of MTP, any
applicable law, rule or regulation.

         4.3 The REIT's Representations and Warranties. As a material inducement
to the MTP Parties to execute this  Agreement and  consummate  the  transactions
contemplated hereunder, the REIT represents and warrants to the MTP Parties that

of  incorporation  and is in good standing in such state and, if  different,  is
qualified to do business and in good standing in the  jurisdictions in which the
property  owned by the REIT or the business  conducted by the REIT requires such
qualification.  Each of the REIT's  subsidiaries  has been duly organized and is
validly  existing  under the laws of its  organization  and,  if  different,  is

obtained any and all consents  required  therefor to enter into this  Agreement.
The persons  signing this  Agreement on behalf of the REIT are  authorized to do
so. This  Agreement  and all of the documents to be delivered by the REIT at the
Closing have been or will be  authorized  and  properly  executed and do or will
constitute the valid and binding  obligations of the REIT,  enforceable  against
the REIT in accordance with their terms.

<PAGE>
                           (ii)  Conflicts.  The execution of and performance by
the REIT under this  Agreement  does not and will not conflict  with the Amended
and  Restated  Articles  of  Incorporation  or  By-Laws of the REIT and does not
breach or violate any  applicable  law, rule or  regulation of any  governmental
authority.  There is no agreement to which the REIT is a party or, to the REIT's
knowledge, binding on the REIT which will be breached by or which is in conflict
with its execution of or performance of its obligations  under this Agreement or
with the rights granted to the REIT hereunder.

                           (iii) Pending  Actions.  There is no action,  suit or

any of its  properties,  which would, if adversely  determined,  have a material
adverse effect on the financial  condition or results of operations of the REIT.
There is no action or proceeding pending or, to the REIT's knowledge, threatened
against  the REIT which  challenges  or impairs  the REIT's  ability to execute,
deliver and perform under this Agreement.

                  (b) REIT Securities Representations and Warranties.

                           (i)  Reserved  Shares.  From the  authorized  capital
stock of the REIT, a  sufficient  number of shares of REIT Stock shall have been

Closing Date, the REIT shall have caused the  effectiveness  of the Registration
Statement  under the Securities Act and under any  applicable  state  securities
laws  covering the resale of the shares of REIT Stock to be issued in accordance
with the Exchange Offer; provided,  however, in the event that this Agreement is
terminated by the REIT pursuant to Section  10.3(d) or Section  10.3(f)  herein,
the REIT shall be entitled  to the prompt  reimbursement  for all  out-of-pocket
costs  (including,  without  limitation,   attorneys'  fees,  filing  fees,  and
disbursements)  incurred  by the REIT in  connection  with its  preparation  and
filing of the Registration Statement and any amendments and supplements thereto.

                           (iii) Registration Statement and Prospectus. When the
Registration Statement becomes effective, (i) the Registration Statement and the
prospectus  included  therein  (the   "Prospectus"),   and  any  amendments  and
supplements  thereto,  will  contain all  statements  and  information  that are
required to be included  therein in accordance  with the  Securities Act and the
applicable rules and regulations of the Securities and Exchange  Commission (the
"Rules and  Regulations")  and will  comply in all  material  respects  with the
requirements  of the  Securities  Act and the  Rules and  Regulations;  and (ii)
neither the  Registration  Statement  nor the  Prospectus,  nor any amendment to
supplement thereto, will include an untrue statement of a material fact
                                       16
<PAGE>
or omit to state a material fact  required to be stated  therein or necessary to
make the statements  therein not misleading;  provided,  however,  that the REIT
makes no  representations  and  warranties  as to  information  contained  in or
omitted from the  Registration  Statement  or  Prospectus,  or any  amendment or
supplement  thereto,  in  reliance  upon  and  in  conformity  with  information
furnished to the REIT by Transferor or MTP  specifically  for use in preparation
thereof.

                  (c)  Brokers'  Fees.  No real estate  broker,  salesperson  or
finder  has  been  engaged  by the  REIT in  connection  with  the  transactions
contemplated  hereby  that may  result  in  claims  for  commissions  or fees in
connection therewith.

                  The term "to the REIT's knowledge" as used in this Section 4.3
shall mean that the officers and directors of the REIT have no actual  conscious
knowledge of facts  inconsistent with the matters stated. In connection with the
foregoing representations, the REIT has made no specific examination of files or
records,  nor has the REIT made inquiry of any other  employee of the REIT,  its
advisor, or any management company of the REIT. No constructive knowledge of any
matter  shall be  imputed  to the  REIT as to  matters  not  within  the  actual
conscious knowledge of the above-named  persons, and no personal liability shall
attach to such  persons as a result of any  violation of any  representation  or
warranty.  A breach of a representation  set forth in this Section 4 by the REIT
shall constitute a failure of the condition set forth in Section 7.2(a).

         4.4  Heritage  LP's  Representations  and  Warranties.  As  a  material
inducement  to the MTP Parties to execute  this  Agreement  and  consummate  the
transactions contemplated hereunder,  Heritage LP represents and warrants to the
MTP Parties that as of the date hereof and as of the Closing Date:

                  (a) Partnership  Organization  and Authority.  Heritage LP has
been duly organized under the Delaware Revised Uniform Limited  Partnership Act,
is validly existing as a Delaware limited  partnership,  and is in good standing
in the State of Delaware.  The Subsidiary  Partnership  will be duly  organized,
validly  existing,  and in good standing in the state of its organization at the
Closing.  Heritage LP is and, at the Closing the Subsidiary Partnership will be,
qualified  to  do  business  and  in  good  standing  under  the  laws  of  each
jurisdiction  in which the  Property  owned or to be owned by Heritage LP or the
Subsidiary  Partnership or the business conducted or to be conducted by Heritage
LP or the  Subsidiary  Partnership  requires  such  qualification.  The REIT and
Heritage SGP are the sole general  partners of Heritage LP and Heritage SGP will
be the sole general partner of the Subsidiary  Partnership.  Heritage LP will be
the sole limited partner of the Subsidiary Partnership. Heritage LP has the full
right and authority and has obtained any and all consents  required  therefor to
enter into this  Agreement  and to  consummate  or cause to be  consummated  the
transactions  contemplated  herein. The persons signing this Agreement on behalf
of Heritage LP at the Closing have been  authorized to do so. This Agreement and
all of the  documents to be delivered by Heritage LP at the Closing have been or
will be authorized and properly executed and do or will constitute the valid
                                       17
<PAGE>
and binding  obligations  of Heritage  LP,  enforceable  against  Heritage LP in
accordance with their terms.

                  (b)  Conflicts.  The  execution  of and  performance  of  this
Agreement does not and will not conflict with the  Partnership  Agreement or the
Certificate  of Limited  Partnership  of Heritage  LP.  There is no agreement to
which Heritage LP is a party or, to Heritage LP's knowledge, binding on Heritage
LP  which  will be  breached  by or is in  conflict  with  its  execution  of or
performance under this Agreement.

                  (c) Pending Actions.  There is no action or proceeding pending
or,  to  Heritage  LP's  knowledge,  threatened  against  Heritage  LP or any of
Heritage LP's properties,  which would, if adversely determined, have a material
adverse  effect on the financial  condition or results of operations of Heritage
LP. There is no action or  proceeding  pending or, to Heritage  LP's  knowledge,
threatened  against  Heritage LP which challenge or impair Heritage LP's ability
to execute, deliver and perform under this Agreement.

                  The term "to Heritage LP's  knowledge" as used in this Section
4.4 shall mean that the general  partners of Heritage LP has no actual conscious
knowledge of facts  inconsistent with the matters stated. In connection with the
foregoing representations, Heritage LP has made no specific examination of files
or records,  nor has Heritage LP made inquiry of any other  employee of Heritage
LP, its  advisor,  or any  management  company of Heritage  LP. No  constructive
knowledge of any matter shall be imputed to Heritage LP as to matters not within
the actual  conscious  knowledge  of the  above-named  persons,  and no personal
liability  shall  attach to such  persons  as a result of any  violation  of any
representation  or  warranty.  A breach  of a  representation  set forth in this
Section 4 by Heritage LP shall  constitute a failure of the  condition set forth
in Section 7.2(a).

         4.5  Disclaimer  of  Warranty.  Except as  expressly  set forth in this
Agreement, the contribution of the Property to Heritage LP is made on an "AS IS"
basis. The REIT Parties  acknowledge that, except as expressly  provided in this
Agreement,   neither   Transferor   nor  any  of  its   agents   have  made  any
representations,  warranties,  promises,  covenants or guaranties of any kind or
character  whatsoever,  express or implied, oral or written, with respect to the
Property or the suitability or fitness of the Property for any particular use or
purpose.

                        ---------------------------------

                  Each of the representations  and warranties  contained in this
Agreement  shall be true and  correct on and as of the  Closing  Date and at all

warranties shall survive the  consummation of the  transactions  contemplated by

irrespective  of any  investigations  or  inquiries  made  by any  party  or any
knowledge  which any party may now  possess or which may  hereafter  come to any
party's  attention,  and  each  party  shall  be  entitled  to  rely  upon  such
representations and warranties irrespective of any investigations,  inquiries or
knowledge.

                                    COVENANTS
                                    ---------

         6.1 Covenants of MTP Parties.  The MTP Parties  agree that,  unless the
REIT otherwise agrees in writing, at all times prior to the Closing Date:

                  (a) Preservation of Business.  The MTP Parties shall use their
best  efforts  to (i)  preserve  intact the  present  business  organization  of
Transferor; (ii) preserve the present goodwill and advantageous relationships of

presently carrying.

                  (b) Actions With Respect to the Property Prior to Closing.

                           (i)  Transferor  agrees  that prior to the Closing it
shall continue to operate and manage the Real Property in the ordinary course of
business in accordance  with past practice  (which  includes the maintenance and
management  of the Property) and shall  perform  regular  maintenance,  maintain
existing  insurance  coverage,  perform  its  obligations  under all leases with
tenants,  Service Contracts and Loan Documents  applicable to the Real Property,
commit no waste to the Property and pay and discharge, in the ordinary course of
business,  liabilities and obligations relating to the Real Property. Transferor
shall not,  without the prior  consent of the REIT,  which  consent shall not be
unreasonably withheld or delayed,  incur, create or assume any new indebtedness,
other than accounts payable,  taxes and similar amounts incurred in the ordinary
course of  business,  nor grant any new lien,  mortgage,  security  interest  or
pledge of any kind on the Real Property prior to the Closing.

                           (ii)  Transferor  agrees that prior to the Closing it
shall consult with the REIT prior to terminating  any Lease or Service  Contract
(except in the ordinary  course of business) or entering  into or modifying  any
contract or agreements  relating to the Real Property  which would be binding on
Heritage  LP or the REIT  after the  Closing.  The REIT  shall have the right to
approve,  such approval not to be unreasonably withheld or delayed, any material
new contracts or contract modifications which are proposed by Transferor.
                                       19
<PAGE>
                           (iii) Transferor may enter into new Leases and modify
existing Leases relating to the Real Property without the REIT's consent so long
as such leases  comply with the  leasing  standards  existing on the date hereof
with respect to the  applicable  property with such  exceptions as are typically
made in the ordinary course of business and are on  Transferor's  standard form,
subject to customary modifications thereto.

                           (iv) Transferor  shall notify the REIT of any matters
that may arise prior to the Closing that could have a material adverse effect on
the Property and become known to the  Transferor,  such as pending or threatened
litigation,  notices  of  violations  from  governmental  or  quasi-governmental
authorities or agencies,  tenant  defaults,  bankruptcies  or  insolvencies  and
asserted landlord defaults.

                           (v) Except with the prior written consent of the REIT
(which  consent shall not to be  unreasonably  withheld or delayed),  Transferor
shall  not  accept  rents or  occupancy  payments  from any  tenant  at the Real
Property  for more than one month in advance  except in the  ordinary  course of
business.

                  (c) Books and Records.  Transferor  shall  maintain its books,
accounts and records in the usual,  regular and ordinary manner,  and on a basis
consistent with prior years,  and shall comply with all laws applicable to it or
to the conduct of its business.

                  (d) Consents and  Approvals.  The MTP Parties shall obtain all
necessary  consents and approvals of other persons and governmental  authorities
to the performance by the MTP Parties of the  transactions  contemplated by this
Agreement.  The  MTP  Parties  shall  make or  cause  to be  made  all  filings,
applications,  statements  and  reports  to all  federal  and  state  government
agencies or entities  that are  required to be made prior to the Closing Date by
or on behalf of the MTP Parties  pursuant to any statute,  rule or regulation in
connection with the transactions contemplated by this Agreement.

                  (e) Access to Property.  During the Due Diligence Period,  and
at all times prior to the Closing  Date,  Transferor  and MTP shall  provide the
REIT  and  Heritage  LP as  well as  their  respective  employees,  contractors,
consultants,  agents and  representatives,  with  complete  access to all files,
books, records and other materials in the possession or control of Transferor or
MTP and  relating to the  Property  and the right to  examine,  inspect and make
copies of such  materials as they may deem  appropriate.  Transferor  shall also
provide  for  such  parties  to have  reasonable  access  to the  Real  Property
(including  the  Improvements  thereon) for the purpose of  conducting  surveys,
architectural,  drainage, soils, mechanical systems,  engineering,  geotechnical
and environmental inspections and tests (including sampling and invasive testing
for the presence of Hazardous Materials performed in connection with Phase I and
Phase II environmental  audits),  feasibility studies and any other inspections,
studies or tests reasonably required by them. The REIT shall also have the right
to conduct a  "walk-through"  of the  Property  prior to the  Closing  Date upon
appropriate notice, subject to the rights of all tenants under their Leases.
                                       20
<PAGE>
                  (f) Information Regarding the Property. It is the intention of
the  parties  that  Transferor  and MTP will  disclose to the REIT and the other
parties  performing  the due diligence  review  herein  provided for any and all
information  in the  possession  or  control  of such  parties,  their  property
managers,  and any other  affiliated  entity to the  extent  it  relates  to the
Property.  In the course of its  investigations,  the REIT may make inquiries to
third parties including,  without limitation,  tenants, the Lender, contractors,
property  managers,  parties to other  contracts and municipal,  local and other
government  officials and  representatives,  and the Transferor consents to such
inquiries.  Transferor  and MTP shall  also make  available  to the REIT all the
books and records, financial statements, income tax returns, contracts, employee
records and other  information  with respect to  Transferor as may be reasonably
required by the REIT in order to perform its due diligence review of Transferor.

                  (g) Truth of Representations  and Warranties.  None of the MTP
Parties  shall take or suffer or permit any action that would render  untrue any
of the  representations or warranties of the MTP Parties in any material respect
herein  contained,  nor  shall  the MTP  Parties  omit to take any  action,  the
omission of which would render untrue any such representation or warranty in any
material respect.

         6.2 Further  Covenants of the MTP Parties.  The MTP Parties agree that,
unless the REIT otherwise agrees in writing,  on or prior to the Commitment Date
Transferor shall deliver:

                  (a)  Identification  of LP Unit  Recipients.  An updated  list
substantially  in the form of Schedule VIII attached hereto  designating (i) the
names of the  partners of  Transferor  that shall  receive LP Units and (ii) the
number of LP Units to be received by each such partner of Transferor.

                  (b)    Representation    Letters.    Representation    Letters

partner of Transferor  designated by Transferor in Schedule VIII attached hereto
and updated pursuant to Section 6.2(a) hereof.

         6.3 Covenants of the REIT  Parties.  The REIT Parties agree that unless
MTP otherwise agrees in writing, at all times prior to the Closing Date:

                  (a) Books and Records.  The REIT Parties shall  maintain their
books,  accounts and records in the usual, regular and ordinary manner, and on a
basis  consistent with prior years, and shall comply with all laws applicable to
them or to the conduct of their business.

                  (b) No Organic  Change.  The REIT Parties  shall not (i) amend
their Articles of Incorporation or bylaws other than the amendment to the REIT's
Articles of  Incorporation  set forth in the REIT's proxy statement  relating to
the REIT's annual meeting of stockholders
                                       21
<PAGE>
to be held on August 20, 1997;  (ii) make any change in their  capital  stock by
reclassification,  subdivision, reorganization or otherwise; or (iii) change the
character of their business.

                  (c) Consents and  Approvals.  The REIT Parties shall use their
best efforts to obtain all necessary consents and approvals of other persons and
governmental  authorities  to  the  performance  by  them  of  the  transactions
contemplated by this Agreement.  The REIT Parties shall make or cause to be made
all  filings,  applications,  statements  and  reports to all  federal and state
government  agencies  or  entities  that are  required  to be made  prior to the
Closing Date by or on behalf of the REIT Parties  pursuant to any statute,  rule
or  regulation  in  connection  with  the  transactions   contemplated  by  this
Agreement.

                  (d) Truth of Representations and Warranties.  The REIT Parties
shall not take or suffer or permit any action  that would  render  untrue in any
material  respect any of the  representations  or warranties of the REIT Parties
herein  contained,  nor  shall the REIT  Parties  omit to take any  action,  the
omission of which would render untrue any such representation or warranty in any
material respect.

                  (e) Indemnity.  Prior to the Closing, the REIT shall not place
any  liens  on the  Property  and will  indemnify,  defend  and hold  Transferor
harmless from all claims and liabilities  (including  reasonable attorneys' fees
and expenses actually  incurred)  asserted against Transferor or its owners as a
result  of any  entry by or on  behalf  of the REIT  onto the  Property.  If any
inspection  or test  disturbs  the  Property,  the REIT will  cause the  damaged
property  to be  restored  to the same  condition  as existed  prior to any such
inspections or tests.

         6.4  Mutual  Consent  to Use Best  Efforts.  Subject  to the  terms and
conditions of this Agreement,  and subject to fiduciary  duties under applicable
law, as advised by counsel,  each of the parties  hereto  agrees to use its best
efforts to take,  or cause to be taken,  all actions,  and to do, or cause to be
done, all things necessary, proper or advisable to consummate and make effective
the transactions contemplated by this Agreement,  including, without limitation,
using its best efforts to make all necessary,  proper or advisable registrations
and filings and obtain all  necessary,  proper or advisable  permits,  consents,
authorizations,  requests  and  approvals  of  third  parties  and  governmental
authorities.  It at any time  after the  Closing  Date,  any  further  action is
necessary or desirable  to carry out the purposes of this  Agreement  (including
providing  any  information  in any way  related to the  assets to be  purchased
pursuant to this Agreement), the proper partners, officers and directors of each
party to this Agreement shall take all such action.

                              CONDITIONS PRECEDENT
                              --------------------

         7.1  Conditions to REIT Parties  Obligation  to Close.  Notwithstanding
anything to the contrary herein, the REIT Parties  obligations at the Closing to
consummate  the  transactions   contemplated  hereunder  (including  the  REIT's
obligations to accept for payment or pay for any
                                       22
<PAGE>
Transferor  Partnership  Interests tendered by a Transferor Partner and Heritage
LP's  obligations to consummate the Asset  Transfer)  shall be contingent on the
satisfaction  of the following  conditions at the Closing (or the waiver thereof
by each of the REIT Parties in their sole and absolute discretion):

                  (a)   Accuracy  of   Representations   and   Warranties.   The
representations and warranties of Transferor  contained herein shall be true and
correct in all  material  respects at Closing as if made as of the Closing  Date
(however,  if a  particular  representation  or  warranty  shall be made only to
Transferor's  knowledge,  then the condition under this Section 7.1(a) shall not
be deemed to be  fulfilled  with  respect to such items unless the same would be
fulfilled if such limitation did not exist; provided, however, in the event that
Transferor  receives notice of a condition within 15 days of the Expiration Date
that would render a particular  representation  or warranty untrue or incorrect,
such Transferor shall be entitled 15 calendar days from such notice to cure such
condition and, if necessary, the Expiration Date shall be extended accordingly).

                  (b) Absence of Action or  Proceeding.  No action or proceeding
by any  governmental  agency shall have been instituted or threatened that would
enjoin,  restrain or prohibit, or that could reasonably be expected to result in
substantial  damages in respect of the Property that in the reasonable  judgment
of the REIT Parties make it inadvisable to consummate such  transaction,  and no
court order shall have been issued in any action or proceeding instituted by any
person that enjoins, restrains or prohibits the consummation of the transactions
contemplated  by this Agreement with respect to Transferor and no proceeding for
such an order shall have been instituted that in the reasonable  judgment of the
REIT or Heritage LP is likely to result in the issuance of such an order.

                  (c) Transferor's Deliveries.  Transferor shall have delivered,
or caused  to be  delivered,  each of the items  specified  in  Section  8.3 and
Section 8.6 hereof that  Transferor is required to deliver and Transferor  shall
have performed in all material respects each of the other  obligations  required
to be performed by it under this Agreement.

                  (d) Compliance with Agreements and Covenants.  Each of the MTP
Parties  shall  have  performed  and  complied  with  each of their  agreements,
covenants,  and  obligations  to be  performed  on or prior to the Closing  Date
except those calling for performance after the Closing Date.

                  (e) Letters of Transmittal Delivery.  The Custodian shall have
delivered,  or caused to be  delivered  to the REIT,  a properly  completed  and
executed Letter of Transmittal for each Transferor Partner  participating in the
Exchange Offer.

                  (f)  Performance or Waiver of Due Diligence.  Prior to 15 days
after receipt of each of the Title  Report,  the Survey,  the UCC Searches,  the
Loan  Documents  or  other  information  to be  provided  or made  available  by
Transferor (the "Due Diligence Period"), the
                                       23
<PAGE>
REIT shall have performed or waived its due diligence  review and examination of
such Title Report,  Survey, UCC Searches,  Loan Documents and all information to
be provided or made  available by  Transferor  and shall have  determined in its
sole and  absolute  discretion,  to proceed with the  transactions  contemplated
under this  Agreement.  It is agreed  that as of the date  hereof,  the REIT has
accepted the physical  condition of the Property as it exists on the date hereof
in all respects;  therefore, the REIT Parties shall not be entitled to terminate
this  Agreement  due to the physical  condition of the  Property.  Except to the
extent covered by a representation or warranty made in this Agreement, a failure
of the REIT to timely  terminate this Agreement  within the Due Diligence Period
shall be a deemed  acceptance by the REIT of all aspects of the condition of the
Property, the Title Report, and the Survey by the REIT.

                  (g) Approval of Title Report, Survey or UCC Searches. The REIT
shall have approved, in its sole discretion,  all matters disclosed by the Title
Report,  Survey or UCC Searches. If any person subsequently issues any amendment
to the Title Report, Survey or UCC Searches disclosing any additional matters or
changes in the legal  description  or additional  requirements  of the REIT, the
REIT shall have  approved  any such matter not  disclosed  by the Title  Report,
Survey or UCC Searches or any previous amendment  thereto.  On or before fifteen
(15) days after the Title  Company has  delivered to the REIT the Title  Report,
Survey or UCC Searches (or any  amendments  thereto) the REIT shall give written
notice of such  approval  or  objection  to  Transferor  and the  Title  Company
specifying  in reasonable  detail any matter to which the REIT  objects.  If the
REIT delivers any notice of objection to any matter,  within five (5) days after
receipt of such objection,  Transferor  shall notify in writing the REIT and the
Title  Company  whether  Transferor  is unable or unwilling to remove or satisfy
such matter objected to by the REIT on or before  Closing.  If the REIT fails to
notify  Transferor  and the Title Company at least twenty (20) days prior to the
Closing Date of any  objections to the Title  Report,  Survey or UCC Searches or
any  amendment  or  modification  thereto,  then the REIT shall be deemed to not
object  to any  matter  in the  Title  Report,  Survey  or UCC  Searches  or any
modification thereto.

                  (h) Title Company  Deliveries.  At the Closing, as a condition
to the REIT Parties  obligation to close, the Title Company shall deliver to the
REIT (i) an Owner's Policy of Title Insurance (the "Title Policy") issued by the
Title Company,  covering the Property in the form  prescribed by the State Board
of  Insurance  for use in Texas,  the  Title  Policy to be dated the date of the
recording of the applicable deed covering the Real Property  covered thereby and
to be in the amount of the Deemed Value of the respective Real Property  covered
thereby (which allocation shall be provided by Transferor), insuring Heritage LP
as owner of good and indefeasible  title to the Survey legal  description of the
Real Property covered thereby and subject only to the Permitted  Exceptions that
are  applicable  to such Real  Property and such  exceptions  as are required by
applicable  Texas law to be  included in Schedule B to each such policy of title
insurance;  and (ii) updated UCC searches from the State of Texas  disclosing no
security  interests  or liens  affecting  the  Property  other  than those to be
released at the Closing and other than those created pursuant to the Transferred

<PAGE>
Property together with any commissions set forth in Schedule IV shall be paid by
Transferor.  The costs of the Title Report,  the Survey and the UCC Searches and
the costs of  recording  any  documents  required  to satisfy  or release  Title
Objections  shall be paid  one-half  by the REIT on  behalf of  Heritage  LP and
one-half by the Transferor  subject to the Title Report,  Survey, or UCC search.
The  premiums for the  standard  Title Policy shall be paid one hundred  percent
(100%)  by  Transferor  immediately  prior  to  the  Closing.  The  cost  of any
additional endorsement or upgrades to the Title Policy shall be paid one hundred
percent (100%) by the REIT.  Notwithstanding  the foregoing,  in connection with
the transfer of the Property and Smith Summit and Park On Preston (collectively,
the "Other  Properties"),  Transferor's  obligation  to pay the premiums for the
Title Policy shall be limited to the amount of premiums that would be payable if

Property and each of the Other Properties,  Transferor shall have the obligation
to pay the full amount of the  premiums for such  separate  title policy for the
Property.  In no event  shall the  Transferor  be liable for the  payment of the
title  premium  associated  with  amending  the  survey  for the  Property.  Any
prepayment  fees or premiums or assumption  fees or costs in connection with the
assumption or repayment of any Mortgage Debt by Heritage LP shall be paid by the
REIT. All costs and expenses described in this Section 8.9 are herein called the
"Property Closing Costs." The parties  acknowledge that certain Property Closing
Costs may not be paid at Closing but will be paid in ordinary  course  following
the Closing.

         8.10  Prorations.  The items in this  Section  8.10 with respect to the
Real  Property  shall be  apportioned  or prorated  between the  Transferor  and
Heritage  LP as of the end of the day  preceding  the  Closing  Date in order to
determine the amount of the Proration with respect to such Property. If the Cash
Payment  considered  payable to  Transferor  pursuant  to Section  2.2(b) is not
received by the Title  Company  before  1:00 p.m.,  Dallas,  Texas time,  on the
Closing Date, the  prorations  shall be made as of the date in which the Closing
occurs (i.e.,  each Transferor  shall receive rents and pay expenses for the day
of Closing with respect to such  Transferor's  Property).  All prorations  other
than the  Dividend  Distribution  Offset set forth in Section  8.10(j)  shall be
based upon a fraction  determined by dividing the number of days elapsed through
the date of the  Closing by 365.  The  parties  shall  compute or  estimate  all
prorations  prior to the Closing Date, and Transferor  shall supply  Heritage LP
before the Closing satisfactory supporting evidence for all such adjustments:

                  (a) Taxes  and  Assessments.  General  real  estate  taxes and
assessments  imposed by governmental  authority ("Taxes") and any assessments by
private  covenant  constituting  a lien or charge on the Real  Property  for the
then-current  calendar year or other current tax period not yet due and payable,
together  with, if  applicable,  state and local taxes  thereon.  If the Closing
occurs  prior to the  receipt  of the tax bill  for the  Real  Property  for the
calendar year or other  applicable tax period for the Real Property in which the
Closing occurs,  Taxes for such calendar year or other applicable tax period for
the Real  Property  shall be prorated  based upon the most recent  ascertainable
assessed values and tax rates.

<PAGE>
                  (b) Collected  Rent.  All collected rent and other income (and
any applicable state or local tax on rent) under Leases in effect at the Closing
but excluding  payments that may  constitute  rent but are provided for in other
subparagraphs of this Section 8.10. Transferor shall be charged with any rentals
collected by Transferor before the Closing, but applicable to any period of time
after such Closing. Any rent and other income delinquent as of the Closing shall
not be prorated.  Heritage LP shall use reasonable  efforts (which efforts shall
not require Heritage LP or the REIT to initiate any lawsuit) to collect any rent
delinquent  as of the  Closing,  and any rent  delinquent  as of the Closing but
collected  after the Closing shall be applied first to current rent  obligations
then to delinquent rent in inverse order of incurrence, with any amounts applied
to any period prior to the Closing remitted to Transferor. Heritage LP may treat
any rent received  after the 27th of any month as rent for the next month.  Once
the Closing has occurred,  Transferor  shall not have any right to seek by legal
action or otherwise  collection of any rents  delinquent for any period prior to
the Closing,  unless the tenant has vacated the premises  under the Lease before
the Closing and the Lease is not assigned to Heritage LP.

                  (c) Utilities.  To the extent such expenses are the obligation
of Transferor and not tenants under Leases,  utilities,  including water, sewer,
electric,  and gas,  based upon the last reading of meters prior to the Closing.
If the utility company will not issue separate bills,  Transferor's portion will
be charged against Transferor and Heritage LP will pay the entire bill after the
Closing.  If Transferor has paid any utilities in advance in the ordinary course
of business, then Transferor shall be credited for Heritage LP's portion of such
payment at the Closing.  The amount of deposits,  if any, with utility companies
that are transferrable and that are assigned by Transferor to Heritage LP at the
Closing shall be credited to Transferor. The amount of any deposits with utility
companies that are not  transferable  and that are not assigned by Transferor to
Heritage LP at the Closing shall remain the property of Transferor.

                  (d) Fees and Charges  Under Service  Contracts.  To the extent
such expenses are the  obligations of Transferor and not of a tenant's under its
Lease,  fees and charges under any Service  Contracts that are being assigned to
and  assumed by  Heritage LP at the Closing on the basis of the periods to which
such Service Contracts relate.

                  (e) Transferred  Debt.  Interest accrued through the day prior
to the Closing Date and not yet due and payable and any principal,  interest and
other  amounts due and payable at the Closing Date  pursuant to the  Transferred
Debt; provided, however, transfer fees due and payable to holders of Transferred
Debt shall be paid in accordance with Section 8.9 hereof.

                  (f)  Insurance.  Premiums or other fees payable in  connection
with any insurance  policies that are being  assigned to and assumed by Heritage
LP at the Closing.

                  (g) Other  Expenses.  All  other  liabilities  related  to the

but only to the extent  that such fees or  commissions  have been  disclosed  to

parties acknowledge that with respect to the majority of Leases, all commissions
due to brokers for the initial term of such Leases have been  previously paid by
the  Transferor  on a "cash out" basis and there will be no  proration  of those

and (B) the total number of calendar  days during the Closing  Quarter  shall be

distribution  of the dividend  payment for the Closing  Quarter  (the  "Dividend
Distribution  Date"), the Dividend  Distribution Offset shall be released to the
REIT; provided, however, in the event that the REIT does not issue a dividend in
the Closing  Quarter,  the Dividend  Distribution  Offset as calculated with the
Dividend Amount shall be released to the Transferor on the Dividend Distribution
Date or in the event that the REIT  issues a  dividend  of less than $.50 in the
Closing  Quarter  (the  "Reduced  Dividend  Amount"),  a portion of the Dividend
Distribution  Offset  equal to the  amount  of the  difference  between  (a) the

of permits and  licenses  assigned by  Transferor  to Heritage LP at the Closing
with the consent or approval,  if required,  of the issuer thereof shall be paid
by Heritage LP.

         8.14 Wages. Transferor shall pay the wages, employment taxes and fringe
benefits  applicable  thereto payable to employees,  if any, of Transferor as of
their discharge on the Closing Date.

         8.15 Escrow Accounts. The parties acknowledge that the Transferred Debt
to be  assumed  has  Escrow  Accounts.  Upon the  Closing  (a) if  requested  by
Transferor, Heritage LP shall reimburse Transferor for the amount Transferor has
deposited into the Escrow  Account with respect to the Real Property,  whereupon
Transferor  shall  assign to Heritage  LP, and Heritage LP shall have sole right

withdraw  all funds that it has  deposited  in each  Escrow  Account,  whereupon
Heritage LP shall make the appropriate deposits into the Escrow Account.

condemnation respecting Real Property, the REIT may, at its option, by notice to

Agreement  and  all  provisions  hereof,  including,   without  limitation,  all
representations and warranties made hereunder, shall inure to the benefit of and
be  binding  upon  the  respective  heirs,   devisees,   legal  representatives,

neither the REIT nor Heritage LP has made any  representation  or warranty  with

received advice in connection with entering into this Agreement and has received

knowledgeably consummate the transactions contemplated by this Agreement.

person or entity as a third party beneficiary, including without limitation, the
Lender.

         12.8  Entirety  and  Amendments.  This  Agreement  embodies  the entire
agreement   between  the  parties  and  supersedes  all  prior   agreements  and
understandings  relating  to the  Property.  This  Agreement  may be  amended or

or cause or permit to be announced or disclosed,  in any manner whatsoever,  the
terms,  conditions  or  substance  of  this  Agreement  or any  of  the  Related
Agreements,  or the transactions  contemplated herein or therein,  without first
obtaining the written  consent of the other parties hereto;  provided,  however,

foregoing  shall not preclude  either party from discussing the substance or any
relevant details of such  transactions  with any of its attorneys,  accountants,
professional  consultants or potential  lenders,  as the case may be, or prevent
either  party  hereto from  seeking to obtain any and all  approvals or consents
necessary in connection with the transactions  contemplated  hereby,  making all
filings  with   governmental   authorities   required  in  connection  with  the
transactions contemplated hereby and complying with laws, rules, regulations and
court orders, including without limitation, governmental regulatory, disclosure,

the  REIT may  release  any  press  notices,  publicity  (oral  or  written)  or
advertising  promotion  relating to, or otherwise  announce or disclose,  in any
manner whatsoever, the terms, conditions and substances of this Agreement or any
of the Related Agreements,  or the transactions  contemplated herein or therein,
without first obtaining the written consent of the other parties hereto.

disbursements, expended or incurred in connection therewith whether at trial, on
appeal or on petition for review.

         12.14 Use of Pronouns.  The use of the neuter singular pronoun to refer
to a party shall be deemed a proper reference,  even though such party may be an
individual,  partnership  or a group of two or more  individuals.  The necessary
grammatical  changes  required to make the provisions of this Agreement apply in
the plural sense where there is more than one seller or purchaser  and to either
partnerships  or individuals  (male or female) shall in all instances be assumed
as though in each case fully expressed.

         Company before 1:00 p.m., Dallas,  Texas time, on the Closing Date, the

         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.  The provisions of this Section 8.10 shall

                                 EXCHANGE OFFER
                                 --------------

         1.1      The Exchange Offer.

                  (a)  Offer to  Purchase.  Provided  that  nothing  shall  have
occurred  that  would  result  in a  failure  to  satisfy  any of the  terms  or
conditions set forth in Article 7 of this Agreement,  as promptly as practicable
following the execution of this Agreement,  the REIT shall commence the Exchange
Offer by delivering  the Exchange  Offer  Documents  (as defined  below) to each
Transferor Partner. Each Transferor Partner that is an Accredited Investor shall
have the right to tender  all or any part of  Transferor  Partnership  Interests
owned by such Transferor Partner (such tendered Transferor Partnership Interests
hereinafter  referred to as "Tendered  Interests")  by executing and  delivering
prior to the Commitment Date to Lincor, as custodian (the "Custodian"), a Letter
of Transmittal  pursuant to which Lincor will make and accept  deliveries by and
on behalf of the Transferor  Partners as provided in the Custody Agreement.  The
obligations  of the REIT to accept for  purchase  and to purchase  any  Tendered
Interests  tendered by the  Transferor  Partners of Transferor  shall be subject
only to the  conditions  set  forth in this  Agreement.  The REIT  shall  not be
entitled to accept for purchase or purchase the Tendered Interests unless all of
the conditions to the  consummation  of the  transactions  contemplated  in this
Agreement are satisfied or waived as provided herein.

                  (b) Purchase  Price.  Subject to the  conditions  set forth in
Article 7 of this  Agreement,  on the Closing Date, the Custodian  shall deliver
the  Letters  of  Transmittal  to the REIT,  and the REIT  shall  deliver to the
Custodian,  as agent for each  Transferor  Partner on whose behalf the Custodian
delivered a Letter of Transmittal, the following:

                           (i) Exchange  Offer Cash Payment.  A wire transfer of
an amount  equal to a portion  of the Total  Cash  Payment  attributable  to the
Transferor Partnership Interests tendered by Transferor Partners in the Exchange
Offer (the "Exchange Offer Cash Payment");  provided, however, in no event shall
the Exchange  Offer Cash Payment  exceed the  difference  between the Total Cash
Payment and the amount of the  Maximum  Property  Closing  Costs as set forth on
Schedule VI attached hereto.

                           (ii) REIT Stock. A certificate registered in the name
of each Transferor Partner that tenders Transferor  Partnership Interests in the
Exchange  Offer  for the  number  of  shares  of  REIT  Stock  equal  to (A) the
difference  between (1) the Exchange Value of all of the Transferor  Partnership
Interests  tendered by such Transferor Partner and accepted for purchase and (2)
that portion of the Exchange Offer Cash Payment  attributable  to the Transferor
Partnership  Interests  tendered by such  Transferor  Partner and  accepted  for
purchase,  divided by (B) the REIT Stock Price.  For purposes of determining the
number of shares of REIT Stock to be issued in the  Exchange  Offer,  Transferor
Partnership  Interests  held  by  one  person  in  multiple  accounts  shall  be
aggregated  and in the event that a Transferor  Partner's  tender of  Transferor
Partnership  Interests  would  result in such  Transferor  Partner  receiving  a
fractional
                                        3
<PAGE>
share of REIT Stock, such fractional share shall be rounded to the nearest whole
share of ASR Common Stock.  The REIT Stock to be issued in  accordance  with the
Exchange  Offer  will  be  duly  authorized,  validly  issued,  fully  paid  and
nonassessable  and will not be subject to any  preemptive  or similar right and,
subject to  compliance  with the  Securities  Act and the Exchange  Act, will be
eligible for listing on the American Stock Exchange.  On or prior to the Closing
Date, the REIT shall have caused the  effectiveness of a registration  statement
(the "Registration Statement") under the Securities Act and under any applicable
state  securities  laws  covering  the  resale of the shares of REIT Stock to be
issued in accordance with the Exchange Offer.

                  (c) Exchange Offer Documents. As soon as practicable after the
Commitment Date, the REIT shall prepare the Registration  Statement covering the
resale of shares of REIT Stock to be offered in the Exchange  Offer,  which will
comply in all material  respects with the  provisions of applicable  federal and
state  securities laws, and will prepare the Letter of Transmittal and a Custody
Agreement   appointing  Lincor  the  Transferor   Partners'  Custodian  to  make
deliveries  for  the  Transferor  Partners  at  the  Closing  (the  Registration
Statement, the Exchange Offer Registration Agreement, the Letters of Transmittal
and the Custody Agreement,  together with any supplements or amendments thereto,
are referred to herein collectively as the "Exchange Offer Documents"). The REIT
shall  prepare  and make all  filings  under  applicable  state Blue Sky Laws to
qualify or exempt  from  qualification  the REIT Stock  offered  pursuant to the
Exchange Offer.

                  (d) Election to Tender Transferor Partnership  Interests.  The
election  of a  Transferor  Partner  to tender  all or a part of the  Transferor
Partnership  Interests  owned by the  Transferor  Partner  shall be made by such
Transferor  Partner's execution of a Letter of Transmittal and the return of the
Letter of  Transmittal to the Custodian for delivery to the REIT pursuant to the
Custody  Agreement.  Following  the  Commitment  Date the  tender of  Transferor
Partnership Interests shall be irrevocable.

                  (e) Consent to  Admission  of REIT as  Partner.  The Letter of
Transmittal  shall provide that each Transferor  Partner  tendering a Transferor

Interest  and  (ii)  waives  any  right  of  first  refusal  granted  under  the

in connection  with the Exchange  Offer.  Lincor,  as a general partner of Smith
Summit GP, and 3636 Colorado,  as a general  partner of Smith Summit GP, consent
to the admission of the REIT as a substituted  limited  partner of Transferor as

                  (f) Term.  The  Exchange  Offer  shall  remain  open until the
commitment  date,  which  shall be 5:00 p.m.,  Dallas,  Texas time on August 11,
1997,  unless  extended  by the REIT and Lincor  (the  "Commitment  Date").  The
Exchange Offer shall expire on the Expiration Date. If the Exchange Offer is not

promptly return the Letter of Transmittal  and all other materials  delivered to
the  Custodian  by the  Transferor  Partner  pursuant to this  Agreement  to the
Transferor  Partner.  Prior to the Commitment  Date, the REIT shall not amend or

         1.2  Tender  of  Lincor's  or 3636  Colorado's  Transferor  Partnership
Interests.  Upon the  terms  and  subject  to the  conditions  set forth in this
Agreement, on the Commitment Date, Lincor and 3636 Colorado shall have the right

shares  of REIT  Stock  pursuant  to the  Exchange  Offer on the same  terms and
subject  to the same  conditions  as set  forth in  Section  1.1  above.  At the
Closing,  the REIT shall  accept for  payment  all  assignments  of the right to
receive  distributions  as a general partner tendered by Lincor or 3636 Colorado
in  Transferor.   If  the  tender  of  the  right  to  receive  general  partner
distributions is accepted,  the REIT shall acquire all right, title and interest
to all distributions  made by Transferor with respect to the interest  acquired,
but the REIT  shall not be  substituted  as a general  partner.  Lincor and 3636
Colorado shall remain as the general partners of Transferor.

         1.3 Internal Revenue Code Section 754 Election. Unless Transferor has a
valid  election  in  place  pursuant  to  Internal  Revenue  Code  Section  754,
Transferor  hereby agrees to make such an election  effective  for  Transferor's
taxable year in which the Exchange Offer is consummated.

         2.2      Contribution of Property to Heritage LP.

                  (a)  Capital  Contributions.  On the Closing  Date,  the REIT,
Heritage SGP and Transferor  shall make the following  capital  contributions to
Heritage LP:

                           (i) The  REIT  and  Heritage  SGP  shall  make a cash
capital   contribution   equal  on  an  aggregate  basis  to  the  REIT  Capital
Contribution which shall be the sum of:

                                    (A) that portion of the Mortgage  Debt to be
repaid or  cancelled  by  Heritage  LP in  accordance  with  Section  2.3 hereof
including, without limitation, any prepayment fees or premiums,  assumption fees
and other costs associated therewith, plus

                                    (B)  the  amount  required  to  satisfy  any
monetary liens which the REIT elects to satisfy pursuant to Section 2.3(d), plus

                                    (C) the Property  Closing  Costs paid and to
be paid by Heritage LP or the REIT  pursuant to Section 8.9,  plus or minus,  as
appropriate

                                    (D) the Prorations, plus

                                    (E) all costs and  expenses  incurred and to
be incurred by Heritage  LP, the REIT or Heritage SGP (on behalf of Heritage LP)
in the performance of its due diligence hereunder, plus

                                    (F) any  amounts  required  to  satisfy  the
obligations  of the  REIT or  Heritage  SGP to  make  capital  contributions  to
Heritage  LP  pursuant  to  Section  4.1.2 or Section  4.1.6 of the  Partnership
Agreement, and plus

                                    (G) cash in the amount of the Asset Transfer
Cash Payment (as defined herein).

                           (ii)  Transferor  shall  contribute  and  convey  the
Property owned by Transferor to Heritage LP as hereinafter provided subject only
to the Transferred Debt as described in Section 2.3 hereof.

                           (iii) Notwithstanding the foregoing,  if, taking into
consideration  the proposed  contributions  to the capital of Heritage LP by the
REIT,  Heritage SGP, and  Transferor in accordance  with Section  2.2(a) hereof,
Heritage LP would not be consolidated with the REIT for financial accounting and
reporting purposes because the respective  Partnership  Interests of the REIT or
Heritage  SGP in  Heritage LP is  insufficient,  then at the Closing the REIT or
Heritage SGP may contribute  cash to Heritage LP in exchange for an amount of GP
Units equal to such cash contribution divided by the REIT Stock Price. Such cash
will be contributed in the
                                        6
<PAGE>
minimum amount sufficient to permit Heritage LP to be consolidated with the REIT
for financial accounting and reporting purposes.

                  (b)  Distribution  of Cash and LP Units.  In exchange  for the
capital  contribution  made by  Transferor  provided in Section  2.2(a)  hereof,
Heritage LP shall distribute the following on the Closing Date:

                           (i) Asset  Transfer  Cash  Payment.  At the  Closing,
Transferor  shall receive by wire  transfer an amount (the "Asset  Transfer Cash
Payment") equal to the Total Cash Payment less the Exchange Offer Cash Payment.

                           (ii) LP Units. At the Closing, Transferor, or certain
partners of Transferor designated by Transferor on Schedule VIII attached hereto
as updated  pursuant to Section  6.2(a)  hereof,  shall  collectively  receive a
number  of LP  Units  that  shall be equal  to (A) the  difference  between  the
Exchange Value  attributable  to Transferor and the amount of the Asset Transfer
Cash  Payment  pursuant  to clause  (i),  divided by (B) the REIT  Stock  Price;
provided,  however,  if such calculation would result in the distribution to the
Transferor, or certain partners of Transferor, of a fraction of an LP Unit, such
fractional  share  shall be rounded to the nearest  whole LP Unit.  In the event
Transferor  distributes  the Asset Transfer Cash Payment to certain  partners of
Transferor,  Transferor  shall  distribute  a number  of LP Units to each of its
partners equal to (A) the difference  between the Exchange Value attributable to
each partner's  interest in Transferor and the amount of the Asset Transfer Cash
Payment distributed to such partner, divided by (B) the REIT Stock Price.

                  (c) Distribution of GP Units. In exchange for the REIT Capital
Contribution  provided in Section 2.2(a) hereof,  Heritage LP shall issue on the
Closing  Date to the REIT and  Heritage  SGP a number of GP Units  (rounded to a
whole unit)  equal to the REIT  Capital  Contribution  divided by the REIT Stock
Price  allocated  between  them on a pro rata basis based upon their  respective
contributions.

         2.3      Assumption of Mortgage Debt.

                  (a)  Mortgage  Debt.  The  REIT,  Heritage  LP and  Transferor
acknowledge and agree that the Property is subject to the Mortgage Debt from the
lender (the "Lender") as described on Schedule II attached hereto.  The Property
shall be acquired by Heritage LP subject to the Mortgage Debt, provided that the
Lender of such Mortgage Debt shall execute a consent,  estoppel letter, transfer
agreement,  and  modification  with  respect to such  Mortgage  Debt as shall be
acceptable to Heritage LP, acting reasonably; provided, however, the Lender will
not be required  to amend any of the  material  legal or  business  terms of the
Mortgage Debt.

                  (b)  Lender  Consent.  From  and  after  the date  hereof  and
continuing for 60 days  thereafter (the "Lender  Consent  Period"),  the parties
shall  proceed  in good  faith and with due  diligence  to attempt to secure any
lender consent and estoppel letter from the Lender and
                                        7
<PAGE>
to negotiate any transfer  agreement or  modifications  to the Loan Documents in
order for Heritage LP to acquire the  Property  subject to such  Mortgage  Debt.
Heritage LP agrees that it shall  accept the  Property  subject to the  Mortgage
Debt,  provided  that  the  Lender  agrees  that  such  Mortgage  Debt  shall be
non-recourse  to  Heritage  LP on the same  terms  that  such  Mortgage  Debt is
currently  non-recourse  to Transferor  and the Lender  executes the  agreements
contemplated  by Section  2.3(a).  Any  Mortgage  Debt to which the  Property is
subject  upon  transfer  to Heritage  LP is herein  referred to as  "Transferred
Debt."

                  (c) Refinancing of Mortgage Debt. In the event that the Lender
does not agree to the transfer of the Mortgage Debt as  contemplated  by Section
2.3(a) and Section 2.3(b), or if for any reason Heritage LP is unable to acquire
the Property  subject to the  Mortgage  Debt within the Lender  Consent  Period,
Heritage  LP shall  have the right to (i)  refinance  all or a  portion  of such
Mortgage  Debt  on  terms  it  determines  to be  acceptable  to it in its  sole
discretion;  (ii) pay all or any portion of such Mortgage Debt from the proceeds
of the REIT Capital  Contribution;  or (iii)  terminate  this  Agreement,  which
rights shall be exercised within the Lender Consent Period.

                  (d)  Indebtedness  Other Than Mortgage Debt.  Transferor shall
satisfy all pecuniary  encumbrances  (other than the Mortgage Debt) or otherwise
have all such  encumbrances  removed as liens  against the Property on or before
the Closing at its own expense.  Transferor shall not place any consensual lien,
encumbrance or easement against the Property  following the date of execution of
this Agreement  without the prior written  consent of the REIT, such consent not
to be unreasonably withheld or delayed. If Transferor fails to satisfy or remove
any  monetary  lien on or prior to  Closing,  the REIT may  proceed  to retain a
portion of the  Exchange  Value  equal to the amount of the  monetary  lien (the
"Holdback  Amount") and reduce the Exchange  Value of the Property  accordingly.
The  Holdback  Amount  shall be paid to  Transferor  at such time as  Transferor
extinguishes  such  monetary  lien.  In  the  event  that  Transferor  does  not
extinguish  such  monetary  lien within 120 days of the Closing  Date,  the REIT
shall apply the Holdback Amount to satisfy the monetary lien.  Transferor  shall
be required to deposit any additional  funds at Closing to satisfy any remaining
monetary liens against the Property.

         2.4 Earnest Money Deposit. Within five (5) days following the Execution
Date,  the REIT shall  deposit  $50,000 in escrow  with the Title  Company  (the
"Earnest  Deposit")  on account of the REIT  Capital  Contribution.  The Earnest
Deposit  shall be placed in an  interest-bearing  account.  At the Closing,  the
Earnest Deposit shall be applied against the Cash Allocation.  In the event this
Agreement is  terminated  for any reason other than as a result of a termination
pursuant to Section  10.3(c),  the Earnest Deposit  required by this Section 2.4
shall be returned to the REIT.  In the event this  Agreement  is  terminated  by
Transferor  pursuant to Section  10.3(c),  the Earnest Deposit  required by this
Section 2.4 shall be paid to Lincor on behalf of Transferor.

                         REPRESENTATIONS AND WARRANTIES
                         ------------------------------

         4.1 Transferor Representations and Warranties. As a material inducement
to the REIT  Parties  to  execute  this  Agreement  and to the REIT  Parties  to
consummate the transactions contemplated hereunder,  Transferor, Lincor and 3636
Colorado  jointly and  severally  represent and warrant to the REIT Parties with
respect to itself  and the  Property,  that as of the date  hereof and as of the
Closing Date:

                  (a) Transferor Organizational Representations and Warranties.

                           (i) Organization  and Authority.  Transferor has been
duly  organized and is validly  existing and in good standing  under the laws of
its jurisdiction of organization and, if different,  is qualified to do business
and in good  standing in the state in which the Property is located.  Transferor
has the full right and authority to enter into this  Agreement.  Transferor  has
the full and right authority to transfer the Property and to consummate or cause
to be consummated the transactions  contemplated herein. This Agreement has been
duly  authorized  and  properly  executed by  Transferor  and,  assuming the due
authorization,  execution  and  delivery  hereof  by the other  parties  hereto,
constitutes the valid and binding obligation of Transferor,  enforceable against
Transferor in accordance with its terms.

                           (ii)  Conflicts.  The execution of and performance by
Transferor  of its  obligations  under  this  Agreement  does  not and  will not
conflict  with the  terms of  Transferor's  constituent  documents  and does not
breach or violate any  applicable  law, rule or  regulation of any  governmental
authority.  Subject to  obtaining  the required  consents  and  approvals by the
Lender,  there is no  agreement  to which  Transferor  is a party or  binding on
Transferor, which will be breached by or which is in conflict with the execution
of or performance by Transferor of its obligations  under this Agreement or with
the rights granted to Transferor hereunder.

                           (iii) Pending  Actions.  There is no action,  suit or
proceeding pending, or to Transferor's knowledge,  threatened against Transferor
or the Property which would, if adversely  determined,  have a material  adverse
effect on the financial condition or results of operations of Transferor.  There
is no action or proceeding  pending,  or to Transferor's  knowledge,  threatened
against Transferor which challenges or impairs  Transferor's ability to execute,
deliver or  perform  under  this  Agreement,  to  transfer  all of the  Property
hereunder or to consummate the transactions contemplated herein.

                  (b) Transferor's Property Representations and Warranties.

                           (i)  Contractors  and  Suppliers.   All  contractors,
subcontractors,  suppliers, architects, engineers and others that have performed
services  or  labor  or  supplied   material  in  connection  with  Transferor's
acquisition,  development, ownership or management of the Property have been, or
will be in the ordinary course of business, paid in full prior to
                                       10
<PAGE>
Closing and all liens  arising  therefrom  (or claims  which with the passage of
time or notice or both,  could  mature into liens) have been,  or will be in the
ordinary  course of business,  satisfied and released  prior to Closing.  On the
Closing Date, Transferor shall provide the REIT a list of all contracts that are
not terminable upon 30 days written notice without penalty. The Transferor shall
not be required to pay any  termination  fees or  penalties in  connection  with
contracts  the REIT  wishes  to  terminate,  as such  amounts  shall be the sole
responsibility  of the REIT.  Notwithstanding  the foregoing  statements,  Smith
Summit   GP   agrees   to   negotiate    on   the   REIT's    behalf   for   the
termination/cancellation  of an existing security  monitoring  agreement between
Smith  Summit  GP and  Network  Multi-Family  Security  Corporation,  with  such
termination  to be effective on August 1, 1998. The REIT agrees and Smith Summit
GP acknowledges that the REIT will bear the cost of $120,000, as a fee to affect
the  termination  of said  contract (the "Buyout  Amount").  The REIT agrees and
Smith  Summit GP  acknowledges  that Smith Summit GP will (a) be entitled to any
savings  obtained if the Buyout Amount is less than  $120,000,  and (b) bear the
responsibility  for any amount in excess of the Buyout  Amount for Smith  Summit
Apartments.  Such  amount in  excess  of the  Buyout  Amount  for  Smith  Summit
Apartments  shall be credited to the REIT with regard to  Transferor  at Closing
and such amount less than the Buyout  Amount shall be credited to  Transferor at
Closing.

                           (ii) Leases and Rent Roll. The Rent Roll delivered by
Transferor hereunder for its Real Property is true, accurate and complete in all
material respects.  Except as set forth in the Rent Roll or applicable Permitted
Exceptions,  there are no leases or occupancy agreements or rights of possession
affecting the Real Property.  Except as otherwise specifically and expressly set
forth in the Rent Roll for the Real  Property:  (1) no presently  effective rent
concessions have been given to any tenants; (2) no rent has been paid in advance
by any tenants  respecting a period  subsequent  to the Closing  (except for the
month in which the  Closing  occurs);  (3) no  tenants  have any  claim  against
Transferor for any deposits,  other than pursuant to the terms of its Lease with
respect to sums  specified as deposits in the Rent Roll; (4) no tenants have any
options or rights of first  refusal to extend or renew  their  Leases or to rent
additional  space  or  to  purchase  the  Property;  (5)  there  are  no  tenant
improvements  which are  incomplete  or which  have not been  fully  paid for by
Transferor except as otherwise specified in this Agreement; and (6) there are no
leasing fees or commissions due, nor will any become due, in connection with any
Lease or any renewal or extension of any Lease.  Except as set forth in the Rent
Roll, no  understanding  or agreement with any party exists as to payment of any
leasing or other fees or commissions  regarding future leases or as to procuring
of tenants  for the Real  Property.  To  Transferor's  knowledge,  no default or
breach  exists on the part of any tenant  except as  provided  in the Rent Roll.
Transferor has not received any notice of any material  default or breach on the
part of the landlord under any Lease.

                           (iii)  Operating  and  Financial   Statements.   Each
Operating and Financial Statement for the Real Property shows all material items
of income and  expense  (operating  and  capital)  incurred in  connection  with
Transferor's  ownership,  operation and management of such Real Property for the
periods indicated and are true, correct and complete in all material respects.

<PAGE>
                           (iv) Notice of Violations. To Transferor's knowledge,
Transferor has not received notice that the Property or the use thereof violates
any laws, rules and regulations of any federal, state, city or county government
or any agency, body or subdivision thereof having any jurisdiction over Property
that have not been resolved to the satisfaction of the issuer of the notice.

                           (v) Zoning,  Applicable Laws Governing  Operation and
Restrictions.  To Transferor's  knowledge,  neither the Property or Transferor's
current use or  operation  thereof  fails to comply or is in  violation,  in any
material  respect,  with  current  applicable  laws,  regulations,   ordinances,
building codes and rules of all applicable  municipal,  local, state and federal
jurisdictions,   including,  without  limitation,  zoning  ordinances,   parking
requirements,  building codes and laws governing access for handicapped persons,
and with restrictions, covenants or similar agreements affecting such Property.

                           (vi)   Taxes   and   Assessments.   To   Transferor's
knowledge,  all taxes for the current  year and all prior years for the Property
which are due and payable have been paid,  except for  installments  due and not
yet  delinquent  and  supplemental  taxes  not yet  assessed,  and no taxes  are
delinquent.  All impact  fees or other  assessments,  fees or  charges,  however
denominated, which may constitute a lien or charge on the Property or which have
been assessed or charged as a result of any permit, license or approval obtained
for the Property have been paid in full, and there is not presently  pending any
such  assessment,  fees or charges of any nature with respect to the Property or
any  part  thereof,   nor  has  Transferor  received  any  notice  of  any  such
assessments,  fees or  charges  being  contemplated.  No areas  within  the Real
Property are subject to any  existing  improvement  districts,  except as may be
disclosed by the applicable Title Report and any amendments  thereto.  All taxes
with  respect to  Transferor  and the  ownership  and  operation of the Property
during Transferor's  ownership,  including,  without limitation,  income,  gross
receipts,  net proceeds, ad valorem,  turnover,  personal property (tangible and
intangible),  sales, use, franchise, excise, value added, stamp, leasing, lease,
user, transfer,  fuel, excess profits,  occupational and interest  equalization,
windfall  profits,  severance  and  employees'  income  withholding  and  Social
Security  taxes  imposed by the United  States or any foreign  country or by any
state,  municipality,  subdivision or instrumentality of the United States or of
any foreign  country or by any other tax  authority,  including  all  applicable
penalties and interest (the "Other Taxes"), which are due and payable, have been
paid as  disclosed  on the  returns to the extent due.  Transferor  has duly and
timely  filed all tax  returns of every  nature  required to be filed by it with
respect to the Other  Taxes,  in every  jurisdiction  in which the same may have
been so required,  and has paid all Other Taxes disclosed on such returns to the
extent  due.  All Other Taxes of which  notice has been  received or which shall
accrue on or prior to the Closing Date have been paid to the extent due.

                           (vii) Hazardous Materials.  The environmental reports

                  (c) Transferor's Securities Representations.

                           (i) Investment  Purpose. In the event that Transferor
receives  LP Units,  Transferor  will  acquire  the LP Units for the  purpose of
transferring  such LP Units to its  partners who intend to hold the LP Units for
investment  and not with a view to or for  sale in  connection  with any  public
distribution thereof within the meaning of the Securities Act.

                           (ii) Sufficient Knowledge and Experience.  Transferor
has  sufficient  knowledge and  experience in financial and business  matters to
enable  it to  evaluate  the  merits  and risks of  investment  in the LP Units.
Transferor has the ability to bear the economic risk of acquiring the LP Units.

                           (iii)  Access  to  Information.  Transferor  has been
supplied  with,  or had access to,  information  to which a reasonable  investor
would attach  significance in making investment  decisions,  including,  but not
limited to, all publicly available filings by the REIT
                                       14
<PAGE>
under the  Securities  Act and the  Exchange  Act,  and the  REIT's  annual  and
quarterly reports to stockholders, any information with respect to Heritage LP's
financial  condition,   business  and  prospects,   and  any  other  information
Transferor has requested,  to answer all of its inquiries  about Heritage LP and
the REIT, and to enable it to make its decision to acquire the LP Units.

                           (iv)  Restrictions  on  Transfer.  Transferor  hereby
acknowledges that neither the LP Units nor the REIT Stock for which LP Units may
be exchanged are registered  under the  Securities  Act or any state  securities
laws  and  cannot  be  resold  without  registration   thereunder  or  exemption
therefrom.  Transferor agrees that, other than the transfers contemplated to its
partners,  it will  not  transfer  all or any  portion  of the LP  Units  or the
underlying  Shares  unless such  transfer has been  registered or is exempt from
registration  under the Securities Act and any applicable state securities laws.
The LP Units  contain a prominent  legend with  respect to the  restrictions  on
transfer under the Securities Act and under applicable state securities laws.

                  (d) ERISA  Representation  and Warranty.  Transferor  holds no
"plan  assets,"  within the meaning of  Department  of Labor  regulations  at 29
C.F.R. section 2510.3- 101, of any employee benefit plan subject to the Employee
Retirement   Income  Security  Act  of  1974,  as  amended   ("ERISA")  and  the
transactions  contemplated  by  this  Agreement  are not  part of an  agreement,
arrangement  or  understanding  designed  to  benefit a party in  interest  with
respect  to  any  employee  benefit  plan  subject  to  ERISA  that  invests  in
Transferor.

                  The term  "to  Transferor's  knowledge"  as it is used in this
Section  4.1 shall mean that the  general  partners  of Smith  Summit GP have no
actual conscious  knowledge of facts  inconsistent  with the matters stated.  In
connection with the foregoing  representations,  Transferor has made no specific
examination  of  files  or  records,  nor has  Transferor  made  inquiry  of any
employees of  Transferor,  its advisor,  or any  management  company  engaged by
Transferor.  No  constructive  knowledge  of any  matter  shall  be  imputed  to
Transferor  as to  matters  not within the  actual  conscious  knowledge  of the
general partners of Smith Summit GP. A breach of a  representation  set forth in
this Section 4 by Transferor, Lincor or 3636 Colorado shall constitute a failure
of the condition set forth in Section 7.1(a) hereof.

execution and delivery of this Agreement,  the  consummation of the transactions
hereby contemplated, and the fulfillment of the terms hereof, will not result in
the  breach of any term or  provision  of, or  constitute  a default  under,  or

party or by which Smith Summit GP or Lincor is bound,  or any judgment,  decree,
order,  or award of any  court,  governmental  body,  or  arbitrator,  or to the

Colorado's  knowledge,  the  execution  and  delivery  of  this  Agreement,  the
consummation of the transactions hereby contemplated, and the fulfillment of the
terms  hereof,  will not  result in the breach of any term or  provision  of, or
constitute a default under,  or conflict with, or cause the  acceleration of any
obligation  under, any agreement or other instrument of any description to which
Smith Summit GP or 3636  Colorado is a party or by which Smith Summit GP or 3636
Colorado  is bound,  or any  judgment,  decree,  order,  or award of any  court,

of Transferor; (ii) preserve the present goodwill and advantageous relationships
of Transferor with all persons having  business  dealings with  Transferor;  and
(iii)  preserve and maintain in force all licenses,  registrations,  franchises,

existing  insurance  coverage,  perform  its  obligations  under all leases with
tenants,  Service Contracts and Loan Documents  applicable to the Real Property,
commit no waste to the Property and pay and discharge, in the ordinary course of
business,  liabilities and obligations relating to the Real Property. Transferor

course of  business,  nor grant any new lien,  mortgage,  security  interest  or
pledge of any kind on the Real Property prior to the Closing.

                           (ii)  Transferor  agrees that prior to the Closing it
shall consult with the REIT prior to terminating  any Lease or Service  Contract
(except in the ordinary  course of business) or entering  into or modifying  any
contract or agreements  relating to the Real Property  which would be binding on
Heritage  LP or the REIT  after the  Closing.  The REIT  shall have the right to
approve,  such approval not to be unreasonably withheld or delayed, any material
new contracts or contract modifications which are proposed by Transferor.

                           (iii) Transferor may enter into new Leases and modify
existing Leases relating to the Real Property without the REIT's consent so long
as such leases  comply with the  leasing  standards  existing on the date hereof
with respect to the  applicable  property with such  exceptions as are typically
made in the ordinary course of business and are on  Transferor's  standard form,
subject to customary modifications thereto.

asserted landlord defaults.

                           (v) Except with the prior written consent of the REIT
(which  consent shall not to be  unreasonably  withheld or delayed),  Transferor
shall  not  accept  rents or  occupancy  payments  from any  tenant  at the Real
Property  for more than one month in advance  except in the  ordinary  course of
business.

                  (d) Books and Records.  Transferor  shall  maintain its books,
accounts and records in the usual,  regular and ordinary manner,  and on a basis

to the conduct of its business.

                  (e) Consents and  Approvals.  The Smith Summit  Parties  shall

this Agreement.

                  (f) Access to Property.  During the Due Diligence Period,  and

inquiries to third parties including,  without limitation,  tenants, the Lender,
contractors,  property managers, parties to other contracts and municipal, local

available to the REIT all the books and records,  financial  statements,  income
tax returns,  contracts,  employee records and other information with respect to
Transferor as may be reasonably required by the REIT in order to perform its due
diligence review of Transferor.

                  (h) Truth of Representations and Warranties. None of the Smith
Summit  Parties  shall  take or suffer or permit any  action  that would  render
untrue any of the  representations  or warranties of the Smith Summit Parties in
any material respect herein  contained,  nor shall the Smith Summit Parties omit
to take  any  action,  the  omission  of  which  would  render  untrue  any such
representation or warranty in any material respect.

                              CONDITIONS PRECEDENT
                              --------------------

         7.1  Conditions to REIT Parties  Obligation  to Close.  Notwithstanding
anything to the contrary herein, the REIT Parties  obligations at the Closing to
consummate  the  transactions   contemplated  hereunder  (including  the  REIT's
obligations  to  accept  for  payment  or pay  for  any  Transferor  Partnership
Interests  tendered by a Transferor  Partner and Heritage  LP's  obligations  to
consummate the Asset  Transfer)  shall be contingent on the  satisfaction of the
following  conditions at the Closing (or the waiver  thereof by each of the REIT
Parties in their sole and absolute discretion):

                  (a)   Accuracy  of   Representations   and   Warranties.   The
representations  and  warranties of the Smith Summit  Parties  contained  herein
shall be true and correct in all  material  respects at Closing as if made as of
the Closing Date (however,  if a particular  representation or warranty shall be
made only to  Transferor's  knowledge  or 3636  Colorado's  knowledge,  then the
condition  under this Section  7.1(a)  shall not be deemed to be fulfilled  with
respect to such items unless the same would be fulfilled if such  limitation did
not exist; provided,  however, in the event that Transferor receives notice of a
condition  within 15 days of the Expiration  Date that would render a particular
representation  or  warranty  untrue  or  incorrect,  such  Transferor  shall be
entitled  15  calendar  days from such  notice to cure such  condition  and,  if
necessary, the Expiration Date shall be extended accordingly).

                  (b) Absence of Action or  Proceeding.  No action or proceeding
by any  governmental  agency shall have been instituted or threatened that would
enjoin,  restrain or prohibit, or that could reasonably be expected to result in
substantial  damages in respect of the Property that in the reasonable  judgment
of the REIT Parties make it inadvisable to consummate such  transaction,  and no
court order shall have been issued in any action or proceeding instituted by any
person that enjoins, restrains or prohibits the consummation of the transactions
contemplated  by this Agreement with respect to Transferor and no proceeding for
such an order shall have been instituted that in the reasonable  judgment of the
REIT or Heritage LP is likely to result in the issuance of such an order.

                  (c) Transferor's Deliveries.  Transferor shall have delivered,
or caused  to be  delivered,  each of the items  specified  in  Section  8.3 and
Section 8.6 hereof that  Transferor is required to deliver and Transferor  shall
have performed in all material respects each of the other  obligations  required
to be performed by it under this Agreement.

                  (d) Compliance  with  Agreements  and  Covenants.  Each of the
Smith  Summit  Parties  shall have  performed  and  complied  with each of their
agreements,  covenants,  and  obligations  to be  performed  on or  prior to the
Closing Date except those calling for performance after the Closing Date.
                                       25
<PAGE>
                  (e) Delivery of Letters of Transmittal and Custody Agreements.
The  Custodian  shall have  delivered,  or caused to be delivered to the REIT, a
properly  completed and executed Letter of Transmittal and Custody Agreement for
each Transferor Partner participating in the Exchange Offer.

                  (f)  Performance or Waiver of Due Diligence.  Prior to 15 days
after receipt of each of the Title  Report,  the Survey,  the UCC Searches,  the
Loan  Documents  or  other  information  to be  provided  or made  available  by
Transferor (the "Due Diligence Period"), the REIT shall have performed or waived
its due  diligence  review and  examination  of such Title Report,  Survey,  UCC
Searches, Loan Documents and all information to be provided or made available by
Transferor  and shall have  determined in its sole and absolute  discretion,  to
proceed with the transactions  contemplated  under this Agreement.  It is agreed
that as of the date hereof,  the REIT has accepted the physical condition of the
Property as it exists on the date hereof in all  respects;  therefore,  the REIT
Parties  shall not be entitled to terminate  this  Agreement due to the physical
condition of the Property.  Except to the extent covered by a representation  or
warranty made in this Agreement,  a failure of the REIT to timely terminate this
Agreement  within the Due Diligence  Period shall be a deemed  acceptance by the
REIT of all aspects of the condition of the Property,  the Title Report, and the
Survey by the REIT.

                  (g) Approval of Title Report, Survey or UCC Searches. The REIT
shall have approved, in its sole discretion,  all matters disclosed by the Title
Report,  Survey or UCC Searches. If any person subsequently issues any amendment
to the Title Report, Survey or UCC Searches disclosing any additional matters or
changes in the legal  description  or additional  requirements  of the REIT, the
REIT shall have  approved  any such matter not  disclosed  by the Title  Report,
Survey or UCC Searches or any previous amendment  thereto.  On or before fifteen
(15) days after the Title  Company has  delivered to the REIT the Title  Report,
Survey or UCC Searches (or any  amendments  thereto) the REIT shall give written
notice of such  approval  or  objection  to  Transferor  and the  Title  Company
specifying  in reasonable  detail any matter to which the REIT  objects.  If the
REIT delivers any notice of objection to any matter,  within five (5) days after
receipt of such objection,  Transferor  shall notify in writing the REIT and the
Title  Company  whether  Transferor  is unable or unwilling to remove or satisfy
such matter objected to by the REIT on or before  Closing.  If the REIT fails to
notify  Transferor  and the Title Company at least twenty (20) days prior to the
Closing Date of any  objections to the Title  Report,  Survey or UCC Searches or
any  amendment  or  modification  thereto,  then the REIT shall be deemed to not
object  to any  matter  in the  Title  Report,  Survey  or UCC  Searches  or any
modification thereto.

                  (h) Title Company  Deliveries.  At the Closing, as a condition
to the REIT Parties  obligation to close, the Title Company shall deliver to the
REIT (i) an Owner's Policy of Title Insurance (the "Title Policy") issued by the
Title Company,  covering the Property in the form  prescribed by the State Board
of  Insurance  for use in Texas,  the  Title  Policy to be dated the date of the
recording of the applicable deed covering the Real Property  covered thereby and
to be in the amount of the Deemed Value of the respective Real Property  covered
thereby (which
                                       26
<PAGE>
allocation  shall be provided by Transferor),  insuring  Heritage LP as owner of
good and indefeasible title to the Survey legal description of the Real Property
covered thereby and subject only to the Permitted Exceptions that are applicable
to such Real Property and such  exceptions  as are required by applicable  Texas
law to be included in  Schedule B to each such  policy of title  insurance;  and
(ii)  updated  UCC  searches  from the  State of Texas  disclosing  no  security
interests or liens affecting the Property other than those to be released at the
Closing  and  other  than  those  created  pursuant  to  the  Transferred  Debt.
Transferor  shall  comply  with all  requirements  to the  issuance of the Title
Policy to be delivered at Closing and shall  execute at Closing such  affidavits
and indemnities as may be appropriate  under  applicable facts and as reasonably
required  by the Title  Company in order for it to issue  such  above-referenced
Title Policy.

                  (i)  Mortgage  Debt.  The Lender  shall have  consented to the
transfer of the Property  subject to the  Transferred  Debt as  contemplated  by
Section  2.3,  or Heritage  LP shall have  agreed to  refinance  or pay off such
Mortgage Debt.

                  (j) Termination of Network Agreement.  The security monitoring
agreement by and between  Network and Smith Summit GP shall have been terminated
in accordance with Section 4.1(b)(i).

                  (k)  Receipt of Opinion of Counsel.  The REIT and  Heritage LP
shall have  received a  favorable  opinion of Kim  Lawrence,  Esq.,  counsel for
Transferor,  in form and substance  satisfactory to the REIT's and Heritage LP's
counsel, dated the Closing Date, and confirming the matters set forth on Exhibit
F attached hereto, subject to customary qualifications.

                  (l) Governmental and Agency Approvals. The REIT or Heritage LP

satisfaction  of each of the following  conditions at the Closing (or the waiver
thereof by Transferor in its sole and absolute discretion):

by any governmental  agency shall have been instituted or threatened which would
enjoin,  restrain or prohibit, or might result in substantial damages in respect
of this Agreement or the consummation of the  transactions  contemplated by this
Agreement,  and would in the  reasonable  judgment of the REIT  Parties  make it
inadvisable to consummate such transactions,  and no court order shall have been
entered in any action or proceeding instituted by any other party which enjoins,

         8.9  Property  Closing  Costs.  All  transfer  fees or stamp  taxes and
recording  fees required to be paid to record the deeds and any loan  assignment
documents with respect to the Property  together with any  commissions set forth
in Schedule IV shall be paid by Transferor.  The costs of the Title Report,  the
Survey and the UCC Searches and the costs of recording any documents required to
satisfy or release Title Objections shall be paid one-half by the REIT on behalf
of  Heritage  LP and  one-half by the  Transferor  subject to the Title  Report,
Survey, or UCC search.  The premiums for the standard Title Policy shall be paid
one hundred percent (100%) by Transferor  immediately prior to the Closing.  The
cost of any additional endorsement or upgrades to the Title Policy shall be paid
one  hundred  percent  (100%) by the REIT.  Notwithstanding  the  foregoing,  in
connection  with the  transfer  of the  Property  and Smith  Summit  and Park On
Preston (collectively,  the "Other Properties"),  Transferor's obligation to pay
the  premiums  for the Title  Policy  shall be limited to the amount of premiums
that would be payable if the  Property  and the Other  Properties  were  insured
together in a single  title  policy,  and  Heritage LP shall pay the premiums in
excess of such amount;  provided,  however,  if the Lender or the lenders of the
mortgage debt to which the Other Properties are subject require separate
                                       34
<PAGE>
title  policies for the Property  and each of the Other  Properties,  Transferor
shall  have the  obligation  to pay the full  amount  of the  premiums  for such
separate  title policy for the  Property.  In no event shall the  Transferor  be
liable for the payment of the title premium  associated with amending the survey
for the Property. Any prepayment fees or premiums or assumption fees or costs in
connection  with the assumption or repayment of any Mortgage Debt by Heritage LP
shall be paid by the REIT. All costs and expenses  described in this Section 8.9
are herein called the "Property  Closing  Costs." The parties  acknowledge  that
certain  Property  Closing  Costs may not be paid at Closing but will be paid in
ordinary course following the Closing.

         8.10  Prorations.  The items in this  Section  8.10 with respect to the
Real  Property  shall be  apportioned  or prorated  between the  Transferor  and
Heritage  LP as of the end of the day  preceding  the  Closing  Date in order to
determine  the amount of the  Proration  with respect to such  Property.  If the
Exchange  Offer Cash Payment  considered  payable to the  Custodian  pursuant to
Section  1.1(b)  and the Asset  Transfer  Cash  Payment  considered  payable  to
Transferor  pursuant to Section  2.2(b) are not  received  by the Title  Company
before 1:00 p.m., Dallas,  Texas time, on the Closing Date, the prorations shall
be made as of the date in which the Closing occurs (i.e.,  each Transferor shall
receive  rents and pay  expenses  for the day of  Closing  with  respect to such
Transferor's  Property).  All  prorations  other than the Dividend  Distribution
Offset set forth in Section 8.10(j) shall be based upon a fraction determined by
dividing the number of days elapsed  through the date of the Closing by 365. The
parties shall compute or estimate all prorations  prior to the Closing Date, and
Transferor shall supply Heritage LP before the Closing  satisfactory  supporting
evidence  for all such  adjustments.  In the event that any of the items in this
Section 8.10 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.  The
provisions of this Section 8.10 shall survive the Closing.

                  (a) Taxes  and  Assessments.  General  real  estate  taxes and
assessments  imposed by governmental  authority ("Taxes") and any assessments by
private  covenant  constituting  a lien or charge on the Real  Property  for the
then-current  calendar year or other current tax period not yet due and payable,
together  with, if  applicable,  state and local taxes  thereon.  If the Closing
occurs  prior to the  receipt  of the tax bill  for the  Real  Property  for the
calendar year or other  applicable tax period for the Real Property in which the
Closing occurs,  Taxes for such calendar year or other applicable tax period for
the Real  Property  shall be prorated  based upon the most recent  ascertainable
assessed values and tax rates.

                  (b) Collected  Rent.  All collected rent and other income (and
any applicable state or local tax on rent) under Leases in effect at the Closing
but excluding  payments that may  constitute  rent but are provided for in other
subparagraphs of this Section 8.10. Transferor shall
                                       35
<PAGE>
be charged with any rentals  collected  by  Transferor  before the Closing,  but
applicable to any period of time after such  Closing.  Any rent and other income
delinquent  as of the  Closing  shall  not be  prorated.  Heritage  LP shall use
reasonable  efforts (which efforts shall not require  Heritage LP or the REIT to
initiate any lawsuit) to collect any rent delinquent as of the Closing,  and any
rent  delinquent  as of the Closing  but  collected  after the Closing  shall be
applied first to current rent  obligations  then to  delinquent  rent in inverse
order of incurrence, with any amounts applied to any period prior to the Closing
remitted to  Transferor.  Heritage LP may treat any rent received after the 27th
of any  month  as rent for the  next  month.  Once  the  Closing  has  occurred,
Transferor  shall  not have  any  right to seek by  legal  action  or  otherwise
collection of any rents  delinquent for any period prior to the Closing,  unless
the tenant has vacated the  premises  under the Lease before the Closing and the
Lease is not assigned to Heritage LP.

                  (c) Utilities.  To the extent such expenses are the obligation
of Transferor and not tenants under Leases,  utilities,  including water, sewer,
electric,  and gas,  based upon the last reading of meters prior to the Closing.
If the utility company will not issue separate bills,  Transferor's portion will
be charged against Transferor and Heritage LP will pay the entire bill after the
Closing.  If Transferor has paid any utilities in advance in the ordinary course
of business, then Transferor shall be credited for Heritage LP's portion of such
payment at the Closing.  The amount of deposits,  if any, with utility companies
that are transferrable and that are assigned by Transferor to Heritage LP at the
Closing shall be credited to Transferor. The amount of any deposits with utility
companies that are not  transferable  and that are not assigned by Transferor to
Heritage LP at the Closing shall remain the property of Transferor.

                  (d) Fees and Charges  Under Service  Contracts.  To the extent
such expenses are the  obligations of Transferor and not of a tenant's under its
Lease,  fees and charges under any Service  Contracts that are being assigned to
and  assumed by  Heritage LP at the Closing on the basis of the periods to which
such Service Contracts relate.

                  (e) Transferred  Debt.  Interest accrued through the day prior
to the Closing Date and not yet due and payable and any principal,  interest and
other  amounts due and payable at the Closing Date  pursuant to the  Transferred
Debt; provided, however, transfer fees due and payable to holders of Transferred
Debt shall be paid in accordance with Section 8.9 hereof.

                  (f)  Insurance.  Premiums or other fees payable in  connection
with any insurance  policies that are being  assigned to and assumed by Heritage
LP at the Closing.

                  (g) Other  Expenses.  All  other  liabilities  related  to the
ownership or operation of the Property  that  Heritage LP may agree to assume or
take subject to in writing.

                  (h) Contractors and Suppliers. Amounts payable to contractors,
subcontractors,  designers, suppliers, architects, engineers and others who have
performed  services  or  labor  or  supplied  material  in  connection  with the
Property.

<PAGE>
                  (i) Leasing Commissions.  Leasing or other fees or commissions
payable in  connection  with any Lease or any renewal or extension of any Lease,
but only to the extent  that such fees or  commissions  have been  disclosed  to
Heritage  LP and the REIT on the Rent  Roll.  For the  avoidance  of doubt,  the
parties acknowledge that with respect to the majority of Leases, all commissions
due to brokers for the initial term of such Leases have been  previously paid by
the  Transferor  on a "cash out" basis and there will be no  proration  of those
commissions at Closing;  however, Heritage LP acknowledges that, as described on
the Rent Roll, commissions for renewals and extensions of such Leases may be due
and  payable in the  future on a "cash out" basis at the time of the  applicable
tenant's  exercise of a renewal or option to extend or may be payable,  for such
extension or renewal, on a monthly basis.

                  (j) Dividend  Distribution  Offset.  An amount (the  "Dividend
Distribution Offset") equal to (i) the product of (A) the total number of shares
of  REIT  Stock  and  LP  Units  issued  in  connection  with  the  transactions
contemplated by this Agreement and (B) $.50 (the "Dividend Amount"),  multiplied
by (ii) the ratio of (A) the  difference  between  the total  number of calendar
days during the quarter in which the Closing occurs (the "Closing  Quarter") and
the number of calendar days during the Closing Quarter prior to the Closing Date
and (B) the total number of calendar  days during the Closing  Quarter  shall be
deposited  in  escrow  by  Transferor  on  the  Closing  Date.  On the  date  of
distribution  of the dividend  payment for the Closing  Quarter  (the  "Dividend
Distribution  Date"), the Dividend  Distribution Offset shall be released to the
REIT;  provided,  however,  in the event that the REIT does not issue a dividend
for the Closing Quarter, the Dividend Distribution Offset as calculated with the
Dividend Amount shall be released to the Transferor on the Dividend Distribution
Date or in the event that the REIT  issues a  dividend  of less than $.50 in the
Closing  Quarter  (the  "Reduced  Dividend  Amount"),  a portion of the Dividend
Distribution  Offset  equal to the  amount  of the  difference  between  (a) the
Dividend Distribution Offset as calculated with the Dividend Amount, and (b) the
Dividend  Distribution  Offset as calculated  with the Reduced  Dividend  Amount
shall be  released  to  Transferor  and the  remaining  amount  of the  Dividend
Distribution  Offset shall be released to the REIT on the Dividend  Distribution
Date.

         8.11  Tenant   Deposits.   All  tenant  deposits,   including   without
limitation,  refundable  security  deposits,  refundable  pet  deposits  and key
deposits,  and advance rental deposits (and interest  thereon if required by law
or contract to be earned  thereon)  shall be  transferred  to Heritage LP at the
Closing, and Heritage LP shall assume the obligations to refund such deposits to
such tenants in accordance with their respective Leases after Closing,  but only
to the extent the obligation to refund such deposits arises after Closing.

         8.12 Income and Sales  Taxes.  All  income,  sales,  gross  receipts or
compensation  taxes and similar  taxes and fees  imposed upon  Transferor  under
applicable local or state law shall be paid by Transferor at the Closing.
                                       37

of permits and  licenses  assigned by  Transferor  to Heritage LP at the Closing
with the consent or approval,  if required,  of the issuer thereof shall be paid
by Heritage LP.

         8.14 Wages. Transferor shall pay the wages, employment taxes and fringe
benefits  applicable  thereto payable to employees,  if any, of Transferor as of
their discharge on the Closing Date.

         8.15 Escrow Accounts. The parties acknowledge that the Transferred Debt
to be  assumed  has  Escrow  Accounts.  Upon the  Closing  (a) if  requested  by
Transferor, Heritage LP shall reimburse Transferor for the amount Transferor has
deposited into the Escrow  Account with respect to the Real Property,  whereupon
Transferor  shall  assign to Heritage  LP, and Heritage LP shall have sole right
and ownership of, all funds in such Escrow Account; or (b) each Transferor shall
withdraw  all funds that it has  deposited  in each  Escrow  Account,  whereupon
Heritage LP shall make the appropriate deposits into the Escrow Account.

reason  of any  insured  or  uninsured  casualty  during  the  period  up to and

disclose  or cause  or  permit  to be  announced  or  disclosed,  in any  manner
whatsoever,  the terms,  conditions or substance of this Agreement or any of the

however, the REIT, in its sole discretion,  may release or cause or permit to be

It is  understood  that the  foregoing  shall not  preclude  either  party  from
discussing the substance or any relevant details of such  transactions  with any
of its attorneys, accountants, professional consultants or potential lenders, as
the case may be, or prevent  either  party hereto from seeking to obtain any and
all  approvals  or  consents  necessary  in  connection  with  the  transactions

to a party shall be deemed a proper reference,  even though such party may be an
individual,  partnership  or a group of two or more  individuals.  The necessary
grammatical  changes  required to make the provisions of this Agreement apply in
the plural sense where there is more than one seller or purchaser  and to either
partnerships  or individuals  (male or female) shall in all instances be assumed
