(the "Title Company"), One Hundred Thirty-Five Thousand Eight Hundred Fifty-Five
Dollars and No/100 Dollars ($135,855.00) (the "Earnest Money Deposit") in cash
or Current Funds, to be held by the Title Company in escrow to be applied or
disposed of by the Title Company as is provided in this Contract. In the event
Purchaser fails to deposit the Earnest Money Deposit with the Title Company as
herein provided, Seller may, at its option, terminate this Contract, in which
event neither Seller nor Purchaser shall have any further obligations hereunder
except for provisions of this Contract which expressly survive the termination
of this Contract. As used in this Contract, the term "Current Funds" shall mean

Title Company which would permit the Title Company to immediately disburse such
funds.

consummated, then the Earnest Money Deposit shall be applied to the Purchase
Price at Closing. In all other events, the Earnest Money Deposit shall be
disposed of by the Title Company as provided in this Contract. The Earnest Money

institution and in a manner reasonably acceptable to Purchaser. All interest

applied or disposed of in the same manner as the Earnest Money Deposit under
this Contract.

of the Earnest Money Deposit with the Title Company, Purchaser shall deliver to
Seller a check in the sum of Fifty and No/100 Dollars ($50.00) (the "Independent
Contract Consideration"), which amount has been bargained for and agreed to as
consideration for Purchaser's right to purchase the Property and the Inspection
Period (hereinafter defined) provided for herein, and for Seller's execution and
delivery of this Agreement. The Independent Contract Consideration is in
addition to and independent of all other consideration provided for in this
Agreement, and is non-refundable in all events.

                                   ARTICLE IV.

                                TITLE AND SURVEY

         4.1 Title Commitment. On or before the Effective Date, Seller shall
cause to be furnished to Purchaser a current Commitment for Title Insurance for
the Land and Improvements (the "Title Commitment") issued by the Title Company.
The Title Commitment shall set forth the state of title to the Land and
Improvements, including a list of conditions or exceptions to title affecting
the Land and Improvements that would appear in an Owner's Policy of Title
Insurance, if one were issued. The Title Commitment shall contain the expressed
commitment of the Title Company to issue the Title Policy (hereinafter defined)
to Purchaser in the amount of the Purchase Price, insuring the title to the Land
and Improvements specified in the Title Commitment. At such time as the Title
Commitment is furnished to Purchaser, the Title Company also shall furnish to
Purchaser copies of instruments or documents (the "Exception Documents") that
create or evidence conditions or exceptions to title affecting the Land and
Improvements, as described in the Title Commitment.


                                       -3-






         4.2 Survey. On or before the Effective Date, Seller shall cause to be
furnished to Purchaser, at Seller's expense, a copy a survey of the Land and
Improvements (the "Survey") dated or recertified no earlier than thirty (30)
days prior to the Effective Date and certified to Purchaser and the Title
Company in a manner reasonably acceptable to Purchaser. Notwithstanding the
foregoing, in the event Purchaser elects to terminate this Contract pursuant to
Section 4.4 or 5.2 hereof, Purchaser shall be obligated to reimburse Seller on
demand for the reasonable expenses incurred by Seller in connection with
obtaining the Survey.

         4.3 Review of Title and Survey. Purchaser shall have until the
expiration of the Inspection Period in which to notify Seller in writing (the
"Title Objection Notice") of any objections Purchaser has to any matters shown
or referred to in the Title Commitment, the Exception Documents or on the
Survey; provided, that Purchaser shall not object to current real estate taxes
and assessments or to easements, restrictions and exceptions affecting the
Property which do not materially adversely affect the value of the Property or
its current use by Seller, all of which shall be Permitted Exceptions hereunder.
Any title encumbrances, exceptions or other matters which are set forth in the
Title Commitment, the Exception Documents or on the Survey, and to which
Purchaser does not object within the Inspection Period, shall be deemed to be
permitted exceptions to the status of Seller's title (such encumbrances,
exceptions or other matters, together with such other matters included pursuant
to other provisions of this Contract, shall be referred to as the "Permitted
Exceptions"). Other than liens securing the payment of the Existing Loan which
will be assumed by Purchaser at Closing pursuant to the terms of this Contract,
Seller shall, notwithstanding anything to the contrary contained herein, satisfy
all liens securing the payment of a monetary obligation and affecting the
Property at or prior to Closing, except for any liens or encumbrances expressly
permitted in Section 4.5(c) and (d) hereof.

         4.4 Objections to Status of Title and Survey. If Purchaser properly
objects to any item shown or referred to in the Title Commitment, Exception
Documents or Survey within the Inspection Period, Seller shall be given until
five (5) days after receipt of the Title Objection Notice to notify Purchaser
whether or not Seller will cure, prior to Closing and at Seller's option and
sole discretion but without any obligation to do so, any objection to the
condition of title raised by Purchaser. If Seller notifies Purchaser that it
elects not to cure any such objections, then Purchaser may, at its option
exercisable within five (5) days following the date of receipt by Purchaser of
written notice from Seller stating that Seller is unable or unwilling to cure
such objections, either (a) accept such title as Seller can deliver, in which
case all exceptions to title set forth in the Title Commitment, Exception
Documents and Survey which are not removed shall be deemed to be Permitted
Exceptions, or (b) terminate this Contract by notice in writing to Seller in
which event the Title Company shall return the Earnest Money Deposit to
Purchaser and neither party shall have any further rights, duties or obligations
hereunder, except for provisions of this Contract which expressly survive
termination of this Contract. In the event Purchaser fails to notify Seller,
within such five (5) day period, that Purchaser has elected to proceed under
either subpart (a) or (b) of the immediately preceding sentence, Purchaser shall
be deemed to have elected to proceed under subpart (a), and this Contract shall
remain in full force and effect. If Seller notifies Purchaser that it elects to
cure any such objections but is unable to cure same by Closing or if Seller
fails to notify Purchaser of its intentions with respect to such objections and
fails to cure same by Closing, then Purchaser

                                       -4-






may, at its option, either (x) accept such title as Seller can deliver in which
case the parties shall proceed with Closing and all exceptions to title set
forth in the Title Commitment, Exception Documents and Survey which are not
removed shall be deemed to be Permitted Exceptions, or (y) terminate this
Contract by notice in writing to Seller at Closing, in which event the Title
Company shall return the Earnest Money Deposit to Purchaser and neither party
shall have any further rights, duties or obligations hereunder except for
provisions of this Contract which expressly survive termination of this
Contract. If any additional exceptions to title other than those shown on the
initial Title Commitment or Survey arise between the date of the initial Title
Commitment, the Survey and the Closing (such exceptions to title being referred
to herein as the "New Exceptions"), Purchaser shall have five (5) business days
after its receipt of written notice of such New Exceptions within which to
notify Seller of any such New Exceptions to which Purchaser objects. Any such
New Exceptions not objected to by Purchaser as aforesaid shall become "Permitted
Exceptions" hereunder; provided, however, all New Exceptions created, caused by,
or consented to by Seller shall be satisfied or removed at Closing and shall not
constitute Permitted Exceptions unless such New Exceptions are expressly
permitted in Section 4.5(c) or (d) hereof. If Purchaser objects to any such New
Exceptions, Seller shall have until Closing to remove such New Exceptions, which
removal may be accomplished by waiver or endorsement by the Title Company
reasonably satisfactory to Purchaser. If Seller fails to remove any such New
Exceptions as aforesaid, Purchaser may, as its sole and exclusive remedy,
terminate this Contract and obtain a return of the Earnest Money Deposit and
neither party shall have any further rights, duties, or obligations hereunder
except for provisions of the Contract which expressly survive the termination of
this Contract. If Purchaser does not elect to terminate this Agreement,
Purchaser shall consummate the Closing and accept title to the Property subject
to all such New Exceptions (in which event, all such New Exceptions, together
with all other Permitted Exceptions, shall be deemed "Permitted Exceptions"
hereunder).

         4.5 Other Permitted Exceptions. The Permitted Exceptions shall include
those matters shown in the Title Commitment and the Survey which become
Permitted Exceptions pursuant to Sections 4.3 and 4.4 above and, in addition,
the following: (a) the Tenant Leases; (b) taxes and assessments for the year in
which Closing occurs and subsequent years that are not yet due and payable; (c)
liens and encumbrances arising after the date hereof to which Purchaser consents
in writing; and (d) any liens or encumbrances of a definite or ascertainable
amount not exceeding $50,000.00 for the Property (and when such amount is added
to the aggregate amounts of any liens or encumbrances to be insured and bonded
around by the respective Dependent Sellers (hereinafter defined) under the
Dependent Contracts (hereinafter defined), such aggregate amount shall not
exceed $125,000.00), provided that (i) Seller causes such liens or encumbrances
to be insured or bonded around such that same do not appear as an exception in
the Title Policy issued to Purchaser pursuant to the Commitment, and (ii) Seller
agrees to indemnify Purchaser from all losses incurred by Purchaser as a result
of such liens or encumbrances.

Property during normal business hours to conduct soil and engineering, hazardous
waste, marketing, feasibility, zoning and other studies or tests and to
otherwise determine the feasibility of the Property for Purchaser's intended
use; provided, however, that prior to conducting any invasive testing with
respect to the Land or Improvements, or any tests or studies which could cause
any damage to the Land or Improvements, Purchaser must advise Seller in writing
(which notice shall state in reasonable detail the nature and extent of such
proposed testing) of its intent to conduct such tests or studies and Seller may,
in its reasonable discretion, refuse to approve any such tests or studies, in
which event Purchaser's sole remedy shall be to terminate this Contract pursuant
to Section 5.2 hereof and receive a refund of the Earnest Money Deposit, all as
provided in said Section 5.2. Seller agrees that, during the Inspection Period,
Seller will allow Purchaser and Purchaser's agents to conduct interviews with
the Tenants set forth on Schedule 5.1 attached hereto and made a part hereof,
and with those certain Tenants which Purchaser notifies Seller in writing during
the Inspection Period that Purchaser desires to conduct interviews and which
Seller consents to, which consent shall not be unreasonably withheld, provided
that such interviews shall take place during normal business hours after
reasonable notice (which may be by telephone) to Seller, and such interviews
shall be conducted only in the presence of one of Seller's representatives. Not
withstanding the foregoing, (a) the costs and expenses of Purchaser's
investigation shall be borne solely by Purchaser, (b) prior to the expiration of
the Inspection Period, Purchaser shall restore the Property to the condition
which existed prior to Purchaser's entry thereon and investigation thereof to
the extent the condition of the Property was affected by or as a result of the

rights of Tenants under Tenant Leases, (d) in the event the transaction
contemplated by this Contract does not close for any reason, Purchaser shall
deliver to Seller a descriptive listing of all tests, reports and inspections
conducted by Purchaser with respect to the Property and deliver copies thereof
to Seller (excluding, however, any proprietary development or marketing
materials), (e) Purchaser shall not permit any mechanic's or materialman's liens
or any other liens to attach to the Property by reason of the performance of any
work or the purchase of any materials by Purchaser or any other party on
Purchaser's behalf in connection with any studies or tests conducted pursuant to
this Section 5.1, (f) Purchaser shall give notice (which may be by telephone) to
Seller a reasonable time prior to entry onto the Property and shall permit
Seller to have a representative present during all investigations and
inspections conducted with respect to the Property, and (g) Purchaser shall take
all reasonable actions and implement all protections necessary to ensure that
all actions taken in connection with the investigations and inspections of the
Property, and all equipment, materials and substances generated, used or brought
onto the Property pose no material threat to the safety of persons or the

                                       -6-






environment and cause no damage to the Property or other property of Seller or
other persons. All information made available by Seller to Purchaser in
accordance with this Contract or obtained by Purchaser in the course of its
investigations shall be treated as confidential information by Purchaser, and,
prior to the purchase of the Property by Purchaser, Purchaser shall use its best
efforts to prevent its agents and employees from divulging such information to
any third parties except (i) as reasonably necessary to third parties engaged by
Purchaser for the limited purpose of analyzing and investigating such
information for the purpose of consummating the transaction contemplated by this
Contract, including Purchaser's attorneys and representatives, prospective
lenders and engineers or (ii) as may required by applicable law, unless such
information is generally available to the public or is disclosed by a party
other than Purchaser or its agents. Purchaser shall indemnify, defend and hold
Seller harmless for, from and against any and all claims, liabilities, causes of
action, damages, liens, losses, costs and expenses (including, without
limitation, reasonable attorneys' fees) incident to, resulting from or in any
way arising out of any of Purchaser's and its agents', contractors' and
representatives' activities on the Property, including, without limitation, any
tests or inspections conducted by Purchaser or its agents, contractors or
representatives on the Property. The agreements contained in this Section 5.1
shall survive the Closing and not be merged therein and shall also survive any
termination of this Contract.

         5.2 Approval of Inspections. If Purchaser determines at any time prior
to the expiration of the Inspection Period that the Property is not satisfactory
to Purchaser, then Purchaser may deliver written notice to Seller within such
Inspection Period, given in accordance with the provisions of Section 13.1
hereof, in which event the Title Company shall return the Earnest Money Deposit
to Purchaser and neither party shall have any further rights, liabilities or
obligations hereunder, except for provisions of this Contract which by their
terms expressly survive the termination of this Contract. If Purchaser does not
timely deliver written notice of termination within such Inspection Period, the
conditions of this Section 5.2 shall be deemed satisfied, and Purchaser shall be
deemed to have approved the condition of the Property and may not thereafter
terminate this Contract pursuant to this Section 5.2. Prior to the end of the
Inspection Period, Purchaser shall deliver written notice (the "Service Contract
Termination Notice") to Seller of any Service Contracts which Purchaser does not
wish to assume; provided, that Purchaser shall be required to assume any Service
Contracts which are not terminable by notice within the time between Seller's
receipt of such Service Contract Termination Notice and the Closing Date

terminated in the Service Contract Termination Notice delivered prior to the end
of the Inspection Period, and any Service Contracts specified in the Service
Contract Termination Notice which cannot be terminated without penalty prior to
the Closing Date, shall be deemed approved by Purchaser and shall be assumed by

of any Commission Agreements which Purchaser does not wish to assume; provided,
that Purchaser shall be required to assume any Commission Agreements which are
not terminable by notice within the time between Seller's receipt of such
Commission Agreement Termination Notice and the Closing Date. Any Commission
Agreements which Purchaser does not specify be terminated in the Commission
Agreement Termination Notice delivered prior to the end of the Inspection
Period, and any Commission Agreements specified in the Commission Agreement
Termination Notice which either cannot be terminated or cannot be terminated
without penalty prior

                                       -7-

         6.4 Effect of Disclaimers. As specified in Section 6.3 above, the
Property will be sold in its "as is" condition. Except for the representations
and warranties of Seller in this Contract and the warranties contained in the
documents to be delivered by Seller to Purchaser at Closing, Purchaser shall
rely on its own due diligence in deciding to enter into and close the
transaction contemplated by this Contract. The price has been negotiated based
upon the "as is" nature of the sale contemplated hereunder.

                                  ARTICLE VII.

                     CONDITIONS PRECEDENT TO PURCHASER'S AND
                              SELLER'S PERFORMANCE

         7.1 Conditions to Purchaser's Obligations. Purchaser's obligation under
this Contract to purchase the Property is subject to the fulfillment of each of
the following conditions (any or all of which may be waived by Purchaser):

                  (a) The representations and warranties of Seller 
         contained herein shall be true, accurate and correct as of the Closing 
         Date;

                  (b) Seller shall be ready, willing and able to deliver title
         to the Property in accordance with the terms and conditions of this
         Contract;

                  (c) The condition specified in Section 7.3 hereof shall have
         been satisfied; and

                  (d) Seller shall have delivered all the documents and other
         items required pursuant to Section 8.2(a), and shall have performed, in
         all material respects, all other covenants, undertakings and
         obligations, and complied with all conditions required by this Contract
         to be performed or complied with by the Seller at or prior to the
         Closing.

         7.2 Conditions to Seller's Obligations. Seller's obligation under this
Contract to sell the Property to Purchaser is subject to the fulfillment of each
of the following conditions (all or any of which may be waived by Seller):

                  (a) the representations and warranties of Purchaser 
         contained herein shall be true, accurate and correct as of the Closing 
         Date; and

                  (b) Purchaser shall have delivered the funds required
         hereunder and all the documents to be executed by Purchaser set forth
         in Section 8.2(b) and shall have performed, in all material respects,
         all other covenants, undertakings and obligations, and complied with
         all conditions required by this Contract to be performed or complied
         with by Purchaser at or prior to Closing.

         7.3 Estoppel Certificates.  Prior to Closing, Seller shall deliver 
to each Tenant an Estoppel Certificate (herein so called), in the form 
attached hereto as Exhibit F, and request that each

                                      -12-






Tenant complete, sign and deliver such Estoppel Certificate to Seller. Seller's
only obligation with respect to such Estoppel Certificates shall be to request
that each Tenant complete and deliver to Seller such Estoppel Certificates.
Purchaser's obligations to consummate the transaction contemplated by this
Contract are expressly subject to and conditioned upon (x) Seller delivering to
Purchaser on or before the Closing Date Estoppel Certificates dated no earlier
than thirty (30) days prior to the Closing Date (unless the Closing Date is
automatically extended pursuant to Section 7.4 hereof, in which case such thirty
(30) day period shall be extended on a day for day basis by the period of the
automatic extension), executed by Tenants occupying at least seventy percent
(70%) of the net rentable area of the Improvements, in the aggregate, and from
all Tenants set forth in Schedule 7.3 attached hereto and made a part hereof
(the "Required Estoppels"), and (y) Seller delivering to Purchaser at Closing a
Seller's Certificate for each Tenant that has not delivered an Estoppel
Certificate on or before Closing. Seller shall be obligated to deliver to
Purchaser at Closing a Seller's Certificate for each Tenant that has not
delivered an Estoppel Certificate on or before Closing. If on or before the
Closing Date Seller has received Estoppel Certificates from Tenants occupying
more than sixty percent (60%) but less than seventy percent (70%) of the net
rentable area of the Improvements, then, at Closing, Seller at its option may
(without any obligation to do so) provide Purchaser with a certificate (herein
called the "Seller's Certificate"), setting forth Seller's certification that,
with respect to the Lease in question for which a Tenant did not deliver an
Estoppel Certificate, (i) the copy of such Lease (and all amendments and
modifications thereto) previously provided by Seller to Purchaser is true,
correct and complete, (ii) Seller has not received any rent thereunder for more
than one month in advance, and (iii) Seller has neither received nor given any
written notice of default under such Lease (or, if so, describing the nature
thereof). Each Seller's Certificate provided to Purchaser as provided in the
immediately preceding sentence shall be in lieu of and in substitution for the
Estoppel Certificate with respect to the Lease in question and shall count
against the minimum seventy percent (70%) requirement set forth in the
conditions set forth above, but only to the extent of such ten percent (10%) or
less shortfall and no Seller's Certificate may be delivered by Seller in
substitution for or count against the requirement to obtain any of the Required
Estoppels. In the event that an Estoppel Certificate is received from a Tenant
either before or within thirty (30) days after Closing which confirms the
accuracy of the certification set forth in the updated and certified rent roll
delivered by Seller to Purchaser at Closing with respect to the corresponding
Lease, the certified and updated rent roll shall be deemed to be superseded by
such Estoppel Certificate and, in such event, Seller shall no longer have any
liability hereunder with respect to that portion of the certification
superseded. In the event that an Estoppel Certificate is received from a Tenant
on or before thirty (30) days after the Closing and delivered by Seller to
Purchaser within such thirty-day period which confirms the accuracy of the
representations made by Seller in a Seller's Certificate delivered by Seller at
Closing, then such Seller's Certificate shall be deemed to be superseded by such
Estoppel Certificate and, in such event, Seller shall no longer have any
liability hereunder with respect to the Seller's Certificate relating to the
Tenant Lease in question. The provisions of this Section shall survive the
Closing and delivery of the Deed.

         7.4 Requisite Approvals. Seller agrees that it will promptly seek the
requisite approval and consent to this Contract and to the sale and transfer of
the Property to Purchaser from the Existing Lender (the "Existing Lender
Approval"). Purchaser shall promptly provide all documents, instruments and
agreements reasonably requested by the Existing Lender in connection with

                                      -13-






obtaining its consent as aforesaid. In the event that Seller has not obtained
the Existing Lender Approval prior to the Closing Date at a cost to Purchaser of
no greater than the sum of (x) an assumption fee of no greater than two percent
(2%) of the outstanding principal balance of the Existing Loan plus (y) any
reasonable costs and expenses of the Existing Lender in connection with such
assumption including, without limitation, attorney's fees, then either Seller or
Purchaser may, at their option, terminate this Contract by delivery of written
notice of termination to the other party, whereupon the Earnest Money Deposit
shall be returned to Purchaser and the parties shall have no further obligations
hereunder except for the provisions of this Contract which by the terms of this
Contract shall survive its termination. Notwithstanding the foregoing, in the
event that Seller has not obtained the Existing Lender Approval on or prior to
the Closing Date, then the Closing Date shall be automatically extended for up
to thirty (30) days to enable Seller to obtain such approval without the
necessity of Seller and Purchaser executing any further amendments to this
Contract.

                                  ARTICLE VIII.

                                     CLOSING

         8.1 Time and Place. The consummation of the purchase and sale of the
Property (the "Closing") shall take place at the office of the Title Company (it
being contemplated that the Closing will occur by the delivery of Closing
documents into escrow with the Title Company) on July 3, 1998, or at such
earlier date and time as Purchaser and Seller may mutually agree (the "Closing

                  Purchaser, and insuring Purchaser's title in the amount of the

                           (ix)  The Assumption Agreement executed by Purchaser.

         8.3 Costs of Closing. The escrow fees of the Title Company shall all be
paid equally by Seller and Purchaser. Any and all costs relating to the Title
Policy and any endorsements thereto shall be borne by Purchaser. Any costs,
including, without limitation, recording costs, loan fees and attorneys' fees,
relating to (a) any financing obtained by the Purchaser for the purchase of the
Property (including, without limitation, any loan assumption fees and expenses
charged by the Existing Lender in connection with the assumption of the Existing
Loan), and/or (b) any documentary stamp taxes, deed taxes, transfer taxes,
intangible taxes, mortgage taxes or other similar taxes, fees or assessments
incurred in connection with any such financing shall be borne and paid
exclusively by Purchaser. All other expenses incurred by Seller and Purchaser
with respect to the Closing, including, but not limited to, the attorneys' fees
and costs and expenses incurred in connection with negotiating, preparing and
closing the transaction contemplated by this Contract, shall be borne and paid
exclusively by the party incurring same, unless otherwise expressly provided in
this Contract.

         8.4 Prorations. All normal and customarily proratable items, including,
without limitation, rents (including, without limitation, base rents, additional
rents, percentage rents and common area maintenance charges but excluding
Delinquent Rent [hereinafter defined] that is more than thirty (30) days past
due) which shall be prorated based upon the updated Rent Roll delivered by
Seller to Purchaser at Closing, operating expenses and other fees and payments
relating to any agreements affecting the Property which survive the Closing,
shall be prorated as of the Closing Date, Seller being charged and credited for
all of same attributable to the period up to the Closing Date (and credited for
any amounts paid by Seller attributable to the period on or after the Closing
Date) and Purchaser being responsible for, and credited or charged, as the case
may be, for all of same attributable to the period on and after the Closing
Date. All unapplied Deposits under Tenant Leases, if any, and all prepaid rents
paid by Tenants under Tenant Leases (but only to the extent such rents are for
periods from and after the Closing Date) shall be credited to Purchaser against
the Purchase Price at the Closing. Any real estate ad valorem or similar taxes
for the Property, or any installment of assessments payable in installments
which installment is payable in the year of Closing, shall be prorated to the
date of Closing, based upon actual days involved. In connection

                                      -17-






with the proration of real property taxes or installments of assessments, such
proration shall be based upon the assessed valuation and tax rate figures for
the year in which the Closing occurs to the extent the same are available;
provided, that in the event that actual figures (whether for the assessed value
of the Property or for the tax rate) for the year of Closing are not available
at the Closing Date, the proration shall be made using figures from the
preceding year for the figures which are unavailable for the year of Closing.
All prorations hereunder shall be final and unadjustable.

         8.5 New Leases. Notwithstanding anything contained in this Contract to
the contrary, Purchaser shall be responsible for the costs of all tenant
improvement expenses and leasing commissions payable or attributable to any new
Tenant Leases entered into by Seller after June 1, 1998 and prior to the Closing
Date; provided, that such new Tenant Leases have been delivered by Seller to
Purchaser for Purchaser's approval and Purchaser has approved of such new Tenant
Leases, which approval shall not be unreasonably withheld, conditioned or
delayed, and which shall be deemed approved if Purchaser has not notified Seller
of its rejection of such new Tenant Lease within three (3) business days after
receipt of a request for approval of such new Tenant Lease from Seller (which
request shall be accompanied by a copy of the Tenant Lease in question and the
amount of any leasing commissions relating thereto). In the event that Seller
has paid any of such expenses and/or leasing commissions prior to Closing,
Purchaser shall reimburse Seller at Closing for the amount of any such expenses
and/or leasing commissions paid by Seller and, in the event Seller has not paid
such expenses and/or leasing commissions prior to Closing, Purchaser shall be
responsible for payment of all such expenses and/or leasing commissions after
Closing.

         8.6 Possession and Closing. Possession of the Property shall be
delivered to Purchaser by Seller at the Closing, subject to the Permitted
Exceptions and the rights of the Tenants under Tenant Leases. Purchaser shall
make its own arrangements for the provision of public utilities to the Property
and Seller shall terminate its contracts with such utility companies that
provide services to the Property.

         8.7 Delinquent Rent.

                  (a) Application of Delinquent Rent. If on the Closing Date any
         Tenant is in arrears in the payment of any rent under any Tenant Lease
         (the "Delinquent Rent") payable by it, any Delinquent Rent received by
         Purchaser and Seller from such Tenant after the Closing shall be
         applied to amounts due and payable by such Tenant during the following
         periods in the following order of priority: (i) with respect to any
         Delinquent Rent which is less than one month late, (A) first, to the
         period of time on or before the Closing Date; and (ii) with respect to
         any Delinquent Rent which is one month or more late as of the Closing
         Date, (A) first, to the period of time after the Closing Date, and (B)
         second, to the period of time on or before the Closing Date. If
         Delinquent Rent or any portion thereof received by Seller or Purchaser
         after the Closing are due and payable to the other party by reason of
         this allocation, the appropriate sum, less a proportionate share of any
         reasonable attorneys' fees and costs and expenses expended in
         connection with the collection thereof, shall be promptly paid to the
         other party. The provisions of this Section 8.7(a) shall survive the
         Closing.


                                      -18-






                  (b) Collection of Delinquent Rent. After the Closing, Seller
         shall continue to have the right, in its own name, to demand payment of
         and to collect Delinquent Rent owed to Seller by any Tenant, which
         right shall include, without limitation, the right to continue or
         commence legal actions or proceedings against any Tenant, but shall
         specifically exclude the right to seek possession of the premises
         demised to a Tenant or to terminate a Tenant Lease, and the delivery of
         the Assignment of Leases [as defined in Section 8.2(a)(iii)] shall not
         constitute a waiver by Seller of such right. Purchaser agrees to
         cooperate with Seller in connection with all efforts by Seller to
         collect such Delinquent Rent and to take all steps, whether before or
         after the Closing Date, as may be necessary to carry out the intention
         of the foregoing, including, without limitation, the delivery to
         Seller, upon demand, of any relevant books and records (including,
         without limitation, rent statements, receipted bills and copies of
         tenant checks used in payment of such rent), the execution of any and
         all consents or other documents, and the undertaking of any act
         reasonably necessary for the collection of such Delinquent Rent by
         Seller, but without any obligation to incur any out-of-pocket costs or
         expenses. The provisions of this Section 8.7(b) shall survive the
         Closing.

         8.8 Tenant Reimbursements. Any additional rents, percentage rents,
common area maintenance charges and other rent items that have accrued, but have
not yet been paid for the calendar year 1997 shall be owned exclusively by
Seller and to the extent any of such amounts are paid by Tenants to Purchaser
after the Closing Date, Purchaser shall promptly deliver such amounts to Seller.
Purchaser acknowledges that based upon the operating expenses of the Property
for calendar year 1997 and based upon projected increases in operating expenses
for calendar year 1998, Seller has notified Tenants in writing that estimated
additional rent payments (the "1998 Additional Rent Payments") are required to
be paid by the Tenants at such time as base rent payments are due and payable
during the balance of the 1998 calendar year. Purchaser agrees that at such time
as the 1998 Additional Rent Payments are received from the Tenants after the
Closing Date, Purchaser shall promptly deliver Seller's Pro rata Portion of such
1998 Additional Rent Payments to Seller. As used in this Section 8.8, Seller's
Pro rata Portion shall be equal to the amount expressed in percentage terms
determined by dividing (x) the number of days that Seller owned the Property in
the 1998 calendar year by (y) 365. The provisions of this Section 8.8 shall
survive the Closing.

                                   ARTICLE IX.

                            CONDEMNATION OR CASUALTY

         9.1 Condemnation.

                  (a) In the event that all or any substantial portion of the
         Property is condemned or taken by eminent domain or conveyed by deed in
         lieu thereof, or if any condemnation proceeding is commenced for all or
         any substantial portion of the Property, prior to Closing, Purchaser
         may elect to terminate this Contract by written notice thereof to
         Seller within ten (10) days after Seller notifies Purchaser of the
         condemnation, taking or deed in lieu or institution of such
         condemnation proceeding, and in the case of such termination, the
         Earnest Money Deposit shall be returned to Purchaser and neither party
         shall have any further rights,

                                      -19-






         duties, or obligations hereunder except for provisions of this Contract
         which expressly survive the termination of this Contract. If Purchaser
         does not terminate this Contract as aforesaid or the taking is not
         substantial, then both parties shall proceed to close the transaction
         contemplated herein pursuant to the terms hereof, in which event Seller
         shall, except as limited in Section 9.1(b) hereof, deliver to Purchaser
         at the Closing any proceeds actually received by Seller attributable to
         the Property from such condemnation, eminent domain proceeding or deed
         in lieu thereof and assign its interest in and to the balance of any
         unpaid proceeds, and there shall be no reduction in the Purchase Price.

                  (b) For the purpose of this Section 9.1(a), a "substantial
         portion" of the Property shall be deemed to be (x) any portion of the
         Improvements, (y) any portion of the Property that restricts or reduces
         the existing access to the Property, or (z) any portion of the parking
         lot that reduces the existing aggregate parking spaces by more than
         five percent (5%) or renders the Property in violation of existing
         zoning requirements. Notwithstanding anything to the contrary contained
         in Section 9.1(a), if Purchaser has not timely elected to terminate in
         accordance with Section 9.1(a), and if the proceeds payable with
         respect to the Property as a result of condemnation exceed the Purchase
         Price for the Property, the portion of such proceeds in excess of the
         Purchase Price shall be paid to Seller (in addition to the Purchase
         Price) at the Closing. The foregoing provision shall survive the
         Closing.

         9.2 Casualty.

                  (a) In the event that all or any substantial portion of the
         Property shall be damaged or destroyed by fire or other casualty prior
         to Closing, Purchaser may terminate this Contract by written notice
         thereof to Seller within ten (10) days after Seller notifies Purchaser
         of the casualty, and in the case of such termination, the Earnest Money
         Deposit shall be returned to Purchaser and neither party shall have any
         further rights, duties, or obligations hereunder except for provisions
         of this Contract which expressly survive the termination of this
         Contract. If Purchaser does not terminate this Contract as aforesaid,
         then both parties shall proceed to close the transaction contemplated
         herein pursuant to the terms hereof, in which event Seller shall,
         except as limited in Section 9.2(b) hereof, deliver to Purchaser at the
         Closing any insurance proceeds actually received by Seller attributable
         to the Property from such casualty (except for proceeds previously used
         to repair the Property) together with any deductible under Seller's
         insurance policy and assign to Purchaser all of Seller's right, title
         and interest in and to any claims which Seller may have under the
         insurance policies covering the Property, and there shall be no
         reduction in the Purchase Price. In the event less than a substantial
         portion of the Property shall be damaged or destroyed by fire or other
         casualty prior to Closing, then the parties shall proceed in accordance
         with the second sentence in this Section 9.2(a).

                  (b) For the purposes of Section 9.2(a), a "substantial
         portion" of the Property shall be deemed to be any portion of the
         Property with either a fair market value or replacement cost in an
         amount equal to or greater than One Hundred Sixty-Five Thousand Two
         Hundred and No/100 Dollars ($165,200.00). Notwithstanding anything in
         Section 9.2(a) to the

                                      -20-






         contrary, if Purchaser has not timely elected to terminate in
         accordance with Section 9.2(a), and if the proceeds payable with
         respect to the Property as a result of casualty exceed the Purchase
         Price for the Property, the portion of such proceeds in excess of the
         Purchase Price shall be paid to Seller (in addition to the Purchase
         Price) at the Closing. The foregoing provision shall survive the
         Closing.

                                   ARTICLE X.

                              DEFAULTS AND REMEDIES

         10.1 Default by Purchaser. If Seller shall not be in default hereunder
and Purchaser refuses or fails to consummate the Closing under this Contract for
reasons other than due to a termination permitted hereunder or other than due to
a failure of a condition precedent to Purchaser's obligation to close as set
forth in Section 7.1 hereof, Seller shall, as its sole and exclusive remedy,
terminate this Contract in which event neither party shall have any further
rights, duties, or obligations hereunder except for provisions of this Contract
which expressly survive the termination hereof, and Seller shall be entitled to
receive and retain the Earnest Money Deposit as liquidated damages (Seller and
Purchaser hereby acknowledging that the amount of damages in the event of
Purchaser's default is difficult or impossible to ascertain but that such amount
is a fair estimate of such damage). Notwithstanding anything contained in this
section to the contrary, in the event of any default by Purchaser of any
indemnity under this Contract which survives the Closing or termination of this
Contract, Seller shall have any and all rights and remedies available at law or
in equity by reason of such default, excluding, however, any punitive,
speculative or consequential damages or damages for loss of opportunity or lost
profit. Except as otherwise provided in this Section 10.1, in no event shall
Purchaser be liable to Seller for any damages, including, without limitation,
any actual, punitive, speculative or consequential damages or damages for loss
of opportunity or lost profit.

         10.2 Default by Seller. If Purchaser shall not be in default hereunder
and if Seller refuses or fails to consummate the Closing under this Contract
other than due to a termination permitted hereunder or a failure of a condition
precedent to Seller's obligation to close as set forth in Section 7.2 hereof,
Purchaser may, at Purchaser's sole option, as its sole and exclusive remedies,
either (a) terminate this Contract in which event neither party shall have any
further rights, duties or obligations hereunder except for provisions of this
Contract which expressly survive the termination hereof, and Purchaser shall be
entitled to a refund of the Earnest Money Deposit, or (b) enforce specific
performance of this Contract. Notwithstanding anything contained in this Section
to the contrary, in the event of (x) (i) any breach by Seller of any
representation or warranty under this Contract which survives the Closing, and
(ii) the Closing occurs under this Contract or (y) any breach by Seller of any
indemnity under this Contract which survives the Closing or termination of this
Contract, in either the case of (x) or (y), Purchaser shall have any rights and
remedies available at law or in equity by reason of such breach, excluding,
however, any punitive, speculative or consequential damages or damages for loss
of opportunity or lost profit. Except as otherwise provided in this Section
10.2, in no event shall Seller be liable to Purchaser for any damages,
including, without limitation, any actual, punitive, speculative or
consequential damages or damages for loss of opportunity or lost profit.

                                      -21-






         10.3 Attorneys' Fees. If it shall be necessary for either Purchaser or
Seller to employ an attorney to enforce its rights pursuant to this Contract,
the non-prevailing party shall reimburse the prevailing party for its reasonable
attorneys' fees.

                                   ARTICLE XI.

                              BROKERAGE COMMISSIONS

         11.1 Brokerage Commission. Seller and Purchaser represent each to the
other that each has had no dealings with any broker, finder or other party
concerning the purchase of the Property except Breunig Commercial Management,
Inc. ( the "Broker"). Seller shall be solely responsible for the payment of any
commission to Broker pursuant to a separate written agreement. Seller represents
and warrants to Purchaser that Broker's right to receive a commission or any
other amount with respect to this Contract or the Property is expressly
conditioned upon Closing the sale of the Property and Seller's receipt of the
Purchase Price under this Contract. Seller represents and warrants to Purchaser
that Broker shall have no right to receive this commission or any other amount
with respect to this Contract or the Property unless and until Closing shall be
final and fully consummated and Seller shall have received the Purchase Price as
provided in this Contract. Seller agrees to indemnify Purchaser and hold
Purchaser harmless from any loss, liability, damage, cost or expense (including,
without limitation, reasonable attorneys' fees) arising out of or paid or
incurred by Purchaser by reason of any claim to any broker's, finder's or other
fee in connection with this transaction by any party claiming by, through or
under Seller (including, without limitation, Broker). Purchaser agrees to
indemnify Seller and hold Seller harmless from any loss, liability, damage, cost
or expense (including, without limitation, reasonable attorneys' fees) arising
out of or paid or incurred by Seller by reason of any claim to any broker's,
finder's or other fee in connection with this transaction by any party claiming
by, through or under Purchaser (excluding Broker). Notwithstanding anything to
the contrary contained herein, the indemnities and other provisions set forth in
this Article XI shall survive the Closing or termination of this Contract.

         Purchaser hereby acknowledges that at the time of the execution of this
Contract, Purchaser is advised by this writing that Purchaser should have an
abstract covering the Property examined by an attorney of Purchaser's own
selection, or that Purchaser should be furnished with or obtain an owner policy
of title insurance.

                                  ARTICLE XII.

                 OPERATION OF THE PROPERTY PRIOR TO THE CLOSING

         12.1 Operation of the Property. Between June 1, 1998 and the Closing
Date, Seller shall (a) lease, operate, manage and enter into contracts with
respect to the Property, in the same manner done by Seller prior to the date
hereof (provided, however, that without the prior consent of Purchaser, which as
to (i) and (ii) shall not be unreasonably delayed, conditioned or withheld, (i)
Seller shall not enter into any Service Contract that cannot be terminated with
thirty (30) days notice or materially modify any existing Service Contracts to
be assumed by Purchaser at Closing, and (ii)

                                      -22-






after June 1, 1998, Seller shall not materially modify or terminate any existing
Tenant Lease or grant any material consents under any existing Tenant Lease
(except as otherwise required pursuant to the terms and conditions of such
Tenant Lease), or enter into any new Tenant Lease, and (iii) Seller shall not
apply any then unapplied Deposits (as reflected on the Rent Roll delivered by
Seller to Purchaser pursuant to Schedule 5.3(vii) hereof) under Tenant Leases);
and (b) advise Purchaser of the commencement of any litigation, condemnation or
other judicial or administrative proceedings affecting the Property of which
Seller has current actual knowledge.

         Notwithstanding anything to the contrary set forth in this Contract,
Purchaser acknowledges that after June 1, 1998 and prior to Closing, Seller will
enter into contracts for the completion of Tenant improvements under Tenant
Leases entered into after June 1, 1998 pursuant to the terms of Section 12.1
hereof (collectively, the "Tenant Finish Contracts"). Purchaser and Seller agree
that at Closing, Purchaser shall assume the obligations of Seller under all such
Tenant Finish Contracts including, without limitation, the obligations to pay
any costs and expenses charged with respect to construction of improvements in
the space subject to such Tenant Leases. At Closing, Purchaser shall execute and
deliver to the Seller an Assignment, Assumption and Indemnity Agreement in the
form attached hereto as Exhibit H and made a part hereof for all purposes.

                                  ARTICLE XIII.

         13.4 Parties Bound. Subject to the provisions of Section 13.5 hereof,
this Contract shall be binding upon and inure to the benefit of Seller and
Purchaser, and their respective heirs, personal representatives, successors and
assigns.

         13.5 Assignment. This Contract may be assigned by Purchaser to any
person or entity controlling, controlled by or under common control with
Purchaser without the prior written consent of Seller. Any assignment of this
Contract by Purchaser other than as provided foregoing shall, at Seller's

Contract by Purchaser, Purchaser shall not be released from any liability or
obligations hereunder.

         13.6 Headings. Headings used in this Contract are used for reference
purposes only and do not constitute substantive matter to be considered in
construing the terms of this Contract.

         13.7 Survival. Except as otherwise expressly provided herein, no
representations, warranties, covenants, acknowledgments or agreements contained
in this Contract shall survive the Closing of this Contract and the delivery of
the Deed by Seller to Purchaser.

         13.8 Interpretation. The parties acknowledge that each party and its
counsel have reviewed this Contract, and the parties hereby agree that the
normal rule of construction to the effect that any ambiguities are to be
resolved against the drafting party shall not be employed in the interpretation
of this Contract or any amendments or exhibits hereto. In case any one or more
of the provisions contained in this Contract shall for any reason be held to be
invalid, illegal or unenforceable in any respect, such invalidity, illegality or
unenforceability shall not affect any other provisions hereof, and this Contract
shall be construed as if such invalid, illegal or unenforceable provisions had
never been contained herein. When the context in which words are used in this
Contract indicates that such is the intent, words in the singular number shall
include the plural and vice versa, and words in the masculine gender shall
include the feminine and neuter genders and vice versa.

         13.9 Exhibits. All references to "Exhibits" contained herein are
references to exhibits attached hereto, all of which are hereby made a part
hereof for all purposes.

         13.10 Time of Essence. It is expressly agreed by the parties hereto
that time is of the essence with respect to this Contract and Closing hereunder.

         13.11 Multiple Counterparts. This Contract may be executed in a number
of identical counterparts. If so executed, each of such counterparts is to be
deemed an original for all purposes, and all such counterparts shall,
collectively, constitute one agreement, but, in making proof of this Contract,
it shall not be necessary to produce or account for more than one such
counterpart.

         13.12 Risk of Loss. Risk of loss or damage to the Property, or any part
thereof, by fire or any other casualty from the date this Contract is fully
executed up to the time of delivering the Deed transferring title to the
Property to the Purchaser will be on the Seller and, thereafter, will be on the
Purchaser.

initialed by Purchaser and Seller.

         13.14 Business Days. All references to "business days" contained herein
are references to normal working business days, i.e., Monday through Friday of
each calendar week, exclusive of federal and national bank holidays. In the
event that any event hereunder is to occur, or a time period is to expire, on a
date which is not a business day, such event shall occur or such time period
shall expire on the next succeeding business day.

         13.15 No Recordation of Contract. In no event shall this Contract or
any memorandum hereof be recorded in the public records of the place in which
the Property is situated, and any such recordation or attempted recordation

the parties were originally obligated to deliver by the terms of this Contract,
such cooperation shall be without additional cost or liability. The provisions
of this Section 13.16 shall survive the Closing for a period of one year.

         13.17 Disclosure: Audit Right.

                  (a) Public Disclosure of Contract. Seller acknowledges that
         Purchaser and/or its general partner, Beacon Capital Partners, Inc.,
         have made and intend in the future to make private and/or public
         securities offerings which are or may be subject to regulation by the
         Securities and Exchange Commission ("SEC"), and that the regulations of
         the SEC may require that Purchaser disclose the existence of this
         Contract and the contents of some or all of the documents and materials
         delivered by Seller. Accordingly and notwithstanding anything to the
         contrary contained in their Contract, Seller expressly consents to the
         disclosure of the terms and conditions of this transaction, this
         Contract itself, and terms of any document or materials which Purchaser
         in good faith believes should be disclosed in connection with
         fulfillment of its disclosure requirements under SEC regulations. In
         addition, Purchaser shall have the right to issue press releases
         announcing this transaction at any time after the expiration of the
         Inspection Period. Seller shall be entitled to a prior review of the
         press release. The provisions of this Section 13.17(a) shall survive
         the Closing.

                  (b) Right to Audit. In order to comply with SEC regulations,
         Purchaser may need the right prior to or subsequent to Closing, to
         conduct an audit of Seller's books and records for the Property in
         conformity with applicable SEC Regulations for prior years and/or for
         Seller's period of ownership during the year in which the Closing
         occurs. Seller hereby

                                      -26-






         agrees, for a period of six months after Closing, to permit Purchaser
         and Purchaser's accountants access to such books and records (including
         those maintained by Seller's management agent for the Property) and to
         cooperate with Purchaser, and to cause Seller's accountants to
         cooperate with Purchaser, at no cost to Seller, to enable such audit to
         be performed. The provisions of this Section 13.17(b) shall survive the
         Closing for a period of six months.

                                  ARTICLE XIV.

                               SPECIAL PROVISIONS

         14.1 Dependent Contracts. Seller and Purchaser acknowledge that on the
Effective Date of this Contract, Purchaser entered into those certain contracts
of sale described in Schedule 14.1 hereof (collectively, the "Dependent
Contracts"). Notwithstanding anything contained in this Contract to the
contrary, Seller and Purchaser agree with respect to the Dependent Contracts as
follows:

                  (a) Purchaser's obligations under this Contract to purchase
         the Property is expressly subject to and conditioned upon the
         consummation of the closing of the acquisition of the properties set
         forth and described in the Dependent Contracts pursuant to the terms
         and conditions thereof;

                  (b) Seller's obligations under this Contract to sell the
         Property to Purchaser is expressly subject to and conditioned upon the
         consummation of the closing of the acquisition of the properties set
         forth and described in the Dependent Contracts pursuant to the terms
         and conditions thereof;

                  (c) A default by Purchaser or any of the sellers (the
         "Dependent Sellers") under any of the Dependent Contracts shall be
         deemed to be a default by Purchaser or Seller, respectively, under this
         Contract and shall entitle such non-defaulting party to the rights and
         remedies set forth in this Contract;

                  (d) The termination by Purchaser of this Contract pursuant to
         a right hereunder automatically terminates each of the Dependent
         Contracts and a termination by Purchaser of any of the Dependent
         Contracts automatically terminates this Contract and the other
         Dependent Contracts and any termination of this Contract by Purchaser
         which entitles Purchaser to receive the Earnest Money Deposit shall
         terminate all of the other Dependent Contracts and the Earnest Money
         Deposit held under this Contract and the earnest money deposits held
         under the Dependent Contracts shall be promptly returned to Purchaser;

                  (e) The termination by Seller of this Contract pursuant to a
         right hereunder automatically terminates each of the Dependent
         Contracts and a termination by any of the Dependent Sellers of any of
         the Dependent Contracts automatically terminates this Contract and the
         other Dependent Contracts and any termination of this Contract by
         Seller which

                                      -27-






         entitles Seller to receive the Earnest Money Deposit shall terminate
         all of the other Dependent Contracts and the Earnest Money Deposit held
         under this Contract shall be promptly paid to Seller and the earnest
         money deposits held under the Dependent Contracts shall be promptly
         paid to the applicable Dependent Sellers; and

                  (f) Notwithstanding anything contained in this Section 14.1
         hereof, in the event of a termination of this Contract or any of the
         Dependent Contracts due to (x) the failure or refusal of Seller to
         consummate the Closing under this Contract (other than due to a
         termination permitted hereunder or a failure of a condition precedent
         to Seller's obligation to close or due to the default of Purchaser
         hereunder) or the failure or refusal of any of the Dependent Sellers to
         consummate the closing under any of the Dependent Contracts (other than
         due to a termination permitted thereunder or a failure of a condition
         precedent to such Dependent Seller's obligation to close or due to the
         default of Purchaser thereunder) or (y) a casualty or condemnation
         pursuant to the terms and provisions set forth in Article IX hereof,
         then at Purchaser's option, the Dependent Contracts and this Contract
         not so terminated shall not be automatically terminated and the
         closings thereunder shall occur pursuant to the terms thereof.

         14.2 Section 1031 Exchange. Purchaser acknowledges that Seller may
elect to transfer its interest in the Property pursuant to a like-kind exchange
qualifying under Section 1031 of the Internal Revenue Code of 1986, as amended.
Purchaser agrees to reasonably cooperate with Seller, subject to the limitations
of this Section 14.3, in order to enable Seller to consummate the transfer of
the Property as part of a like-kind exchange qualifying pursuant to Section
1031.

         The exchange is not to occur simultaneously with the conveyance of the
Property and, therefore, Purchaser will, upon Seller's request, cooperate with
Seller in a "delayed exchange". Pursuant to a delayed exchange, Purchaser will
acquire the Property from a third party designated by Seller who will be
contractually bound to (i) acquire replacement property designated by Seller and
(ii) transfer the designated replacement property to Seller as part of Seller's
exchange with the third party; provided, that notwithstanding that Purchaser may
acquire the Property from such third party, Properties of Floyd Road, Ltd. will
remain obligated as the Seller under this Contract, and all representations,
warranties, covenants, agreements and obligations which survive the Closing and
are binding upon the Seller hereunder shall survive and continue as
representations, warranties, covenants, agreements and obligations of Properties
of Floyd Road, Ltd.

         To accomplish Seller's goal in either case, Purchaser shall execute or
consent to such additional documents and transactions as may be reasonably
requested by Seller, including, but not limited, to any assignments of documents
or interest in the contemplated transactions, provided that (a) there shall be
no delay in the Closing Date and the consummation of the transactions
contemplated in this Contract; (b) Seller shall not be released if the exchange
fails for any reason and in such event only Seller shall remain obligated to
consummate the transaction contemplated in this Contract; (c) Seller shall
reimburse Purchaser for any and all costs reasonably incurred by Purchaser as a
result of the exchange or attempted exchange; (d) Purchaser need not assume any
additional liabilities or obligations as a result of the exchange or attempted
exchange; and (e) Seller shall not

                                      -28-






be released from any representations, warranties, covenants, agreements or
obligations hereunder as a result of the exchange or attempted exchange.

         Seller shall fully indemnify, defend and hold Purchaser harmless for,
from and against any and all liabilities, claims, damages, expenses (including,
without limitation, reasonable attorneys' fees), taxes, fees, proceedings and
causes of action of any kind or nature whatsoever arising out of, connected with
or in any manner related to such Section 1031 exchange or attempted exchange.
The provisions of the immediately preceding sentence shall survive Closing and
the transfer of title to the Property to Purchaser. Any Section 1031 exchange
shall be consummated in such a manner that Purchaser shall not be required to
acquire title to any real or personal property other than the Property, or incur
any liability, in connection therewith.

         IN WITNESS WHEREOF, the undersigned have executed this Contract
effective as of the Effective Date.
