         2.1 Purchase Price. The total Purchase Price (herein so called) to be
paid by Purchaser to Seller for the Property shall be an amount equal to Four
Million One Hundred Eighty Thousand and No/100 Dollars ($4,180,000.00). The

                                  ARTICLE III.

                EARNEST MONEY; INDEPENDENT CONTRACT CONSIDERATION

         3.1 Amount and Timing. Within two (2) business days after the Effective

Company, located at 8117 Preston Road, Suite 100, Dallas, Texas 75225,
Attention: J. David Griffin, Esq. (the "Title Company"), One Hundred
Thirty-Seven Thousand Five Hundred and No/100 Dollars ($137,500.00) (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 wire transfers, certified
funds or cashier's checks in a form acceptable to the Title Company which would

Deposit shall be invested in an interest-bearing account with a financial
institution and in a manner reasonably acceptable to Purchaser. All interest
earned on the Earnest Money Deposit is part of the Earnest Money Deposit, to be

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.

         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"). 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

                                       -3-






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 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

                                       -4-






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.

                                   ARTICLE V.

                             INSPECTION BY PURCHASER

         5.1 Inspection Period. Purchaser shall have a period of time commencing
on the Effective Date and expiring at 5:00 p.m., Dallas, Texas time on June 17,
1998 (the "Inspection Period") within which to examine the Property and to
conduct its feasibility study thereof. Seller agrees that, during the Inspection
Period, Seller will allow Purchaser and Purchaser's agents access to the
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
actions of Purchaser or its agents, contractors or representatives, (c)
Purchaser shall not, in Seller's reasonable opinion, materially interfere,
interrupt or disrupt the operation of Seller's business on the Property and,
further, such access by Purchaser and/or its agents shall be subject to 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,

                                       -5-






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 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
(hereinafter defined). Any Service Contracts which Purchaser does not specify be
terminated in the Service Contract Termination Notice delivered prior to the end

Purchaser at Closing. Prior to the end of the Inspection Period, Purchaser shall
deliver written notice (the "Commission Agreement Termination Notice") to Seller
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 to the Closing Date shall be deemed approved by Purchaser
and shall be assumed by Purchaser at Closing.

                                  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

                                      -11-






                  (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 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 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

                                      -12-






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.

         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.

                  (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,

                                      -17-






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, 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.

                                      -18-






         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-Seven Thousand Two
         Hundred and No/100 Dollars ($167,200.00). Notwithstanding anything in
         Section 9.2(a) to the 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

                                      -19-






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.

         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

                                      -20-






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) 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.

                                      -21-

         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 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

                                      -25-






         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 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.

                                      -26-






         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, Forest Abrams Place, 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 Forest
Abrams Place, 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 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.

                                      -27-
