other interests in, on, under or to, any land, highway, street, road,
right-of-way or avenue, open or proposed, in, on, under, across, in front

grade thereof;

(d) the accessions, appurtenant rights, privileges, appurtenances and
all the estate and rights of Seller in and to the Land and the
Improvements, as applicable, or otherwise appertaining to any of the
property described in the immediately preceding clauses (a), (b) and/or
(c);

(e) all personal property, including, without limitation, the personal
property listed in Exhibit B attached hereto, owned by Seller and located
on or in or used solely in connection with the Land and Improvements, but
expressly excluding all computer programs and computer software
(collectively, the "Personal Property"); and

(f) To the extent assignable without cost to Seller, all of Seller's
interest in all permits, warranties, guaranties, plans, specifications,
reports, books and records, and any intangible property, ("Intangible
Property") now or hereafter owned by Seller and used in connection with the
Land, Improvements and Personal Property, including without limitation the
right to use any trade style or name now used in connection with the same,
any contract rights, escrow or security deposits, utility agreements or
other rights related to the ownership of or use and operation of the
Property, as hereinafter defined.

All of the items described in subparagraphs (a), (b), (c), (d), (e) and (f)
above are collectively referred to in this Agreement as the "Property". The
items described in subparagraphs (a), (b), (c), and (d) above are collectively
referred to in this Agreement as the "Real Property".

1.2. Title. Seller shall convey to Buyer by general warranty deed (the
"Deed"), and Buyer shall accept fee simple title to the Real Property and title
to the other Property in accordance with the terms of this Agreement, and
Buyer's obligation to accept said title shall be conditioned upon Buyer then
being conveyed good and clear record and marketable fee simple title to the Real
Property, subject only to the Permitted Exceptions (as hereinafter defined) and
the issuance of the Buyer's Title Policy (as hereinafter defined), provided that
Buyer has satisfied all of its closing conditions necessary for the issuance of
the Buyer's Title Policy (including, without limitation, payment of the Purchase
Price).

As promptly as possible after the date of this Agreement Seller shall, at
its sole expense, obtain from LandAmerica Title Insurance Corporation, Boston
NCS office, Attention: ▇▇▇▇▇▇ ▇▇▇▇▇, Esq. (the "Title Insurer") a Commitment For
a TLTA T-1 Owner's Title Insurance Policy for the Real Property (when issued,
the "Buyer's Title Policy") together with copies of all instruments and plans
mentioned therein as exceptions to title (all of such items are hereinafter
collectively referred to as the "Title Commitment"). The Title Commitment shall
be in the amount of the Purchase Price (as defined in Section 2.1 hereof).
Should such Title Commitment contain any title exceptions which are not
acceptable to Buyer, in its sole discretion, Buyer may,

prior to the expiration of the Inspection Period (as defined in Section 6.2
hereof), notify Seller in writing of such fact. If Buyer fails to so notify
Seller of any unacceptable exceptions as described above, the exceptions set
forth in Schedule B of the Title Commitment shall be deemed accepted by Buyer.
If any exceptions are unacceptable to Buyer and Buyer timely notifies Seller in
writing of such fact as above provided, Seller, in Seller's sole discretion,
shall have thirty (30) days from the date Seller receives notice of such
unacceptable exceptions to remove or cure such exceptions, except with respect
to the Mortgage Liens (as hereinafter defined), which Seller shall satisfy and
cause to be removed or otherwise insured over at Closing with the proceeds from
the Purchase Price. Seller shall be deemed to have given notice to Buyer that
Seller refuses to cure any unacceptable exceptions, which Seller may so do in
its sole discretion, unless Seller, within ten (10) days after receipt of
written notice from Buyer, shall notify Buyer in writing that Seller will
attempt to cure such unacceptable exceptions. If Seller fails or refuses to cure
said unacceptable exceptions within the time period above provided, Buyer may
(a) terminate this Agreement within ten (10) days after Seller gives notice, or
is deemed to have given notice, that Seller refuses or is unable to cure such
unacceptable exceptions and the Deposit (as defined in Section 2.4) shall be
returned to Buyer, or (b) if Buyer fails to so terminate, Buyer shall be deemed
to have waived such exceptions and accepted title to the Real Property subject
thereto, in which event there shall be no reduction in the Purchase Price. If
Buyer shall fail to give notice it shall be deemed to have elected option (a)
above. Notwithstanding the foregoing, Seller, at its cost, shall be obligated to
cure or remove by Closing all mortgages and deeds of trust against title to the
Property (collectively, the "Mortgage Liens") and other monetary liens not
exceeding $50,000 in the aggregate.

1.3. Survey. Seller shall furnish Buyer with a copy of the most recent
as-built survey of the Land and the Improvements in Seller's possession (the
"Prior Survey"), and on or before the expiration of the Inspection Period, Buyer
may, at its sole expense, obtain a current as-built survey (the "New Survey") of
the Land and the Improvements prepared by a registered land surveyor.

Should the Prior Survey contain any encumbrances, encroachments or other
survey defects (collectively "Prior Survey Matters") which are not acceptable to
Buyer in its sole discretion, Buyer may, prior to the expiration of the
Inspection Period, notify Seller in writing of such fact. In addition, if Buyer
obtains a New Survey and it contains any encumbrances, encroachments or other
survey defects which do not appear on the Prior Survey (collectively, "New
Survey Matters") and which are not acceptable to Buyer in its sole discretion,
Buyer may, not later than the expiration of the Inspection Period, notify Seller
in writing of such fact. Prior Survey Matters and New Survey Matters are
collectively referred to in this Agreement as "Survey Matters". If Buyer fails
to timely notify Seller in writing of any unacceptable Survey Matters as
described above, all Survey Matters shall be deemed accepted by Buyer and shall
become Permitted Exceptions pursuant to Section 1.4. If any Survey Matters are
unacceptable to Buyer and Buyer timely notifies Seller in writing of such fact
as above provided, Seller, in Seller's sole discretion, shall have thirty (30)
days from the date Seller receives notice of such unacceptable Survey Matter(s)
to cure same. Seller shall be deemed to have given notice to Buyer that Seller
refuses to cure any unacceptable Survey Matters, which Seller may so do in its
sole discretion, unless Seller, within ten (10) days after receipt of written
notice from Buyer, shall notify Buyer in writing that Seller will attempt to
cure such unacceptable Survey Matters.

If Seller fails or refuses to cure said unacceptable Survey Matters within the
time period provided, Buyer may (a) terminate this Agreement within ten (10)
days after Seller gives notice, or is deemed to have given notice, that Seller
refuses to cure such unacceptable Survey Matters and the Deposit shall be
returned to Buyer, or (b) if Buyer fails to so terminate, Buyer shall be deemed
to waive such Survey Matters and accept title to the Real Property subject
thereto, in which event there shall be no reduction in the Purchase Price.

1.4. Permitted Exceptions. The following items are hereinafter referred to
as the "Permitted Exceptions":

(a) all possible title objections, survey objections, and any defects
in or to title to the Property or other matters affecting or relating to
the title to, or the survey of, or the condition of the Property existing
as of the expiration of the Inspection Period and not objected to by Buyer
and/or which Buyer has otherwise approved or is deemed to have approved
pursuant to Section 1.2 and/or Section 1.3;

(b) all Leases described on Exhibit C and all Service Contracts
described on Exhibit D, or which Seller is permitted to enter into pursuant
to this Agreement;

(d) rights of parties in possession as tenants under unrecorded
written leases not shown by the public records, and any subtenants or
licensees under any Leases;

(e) discrepancies, conflicts in boundary lines, shortages in area,

installation, connection, maintenance or construction charges due after

are caused or created by or on behalf of Buyer or any of Buyer's agents,
employees or representatives.

SECTION 2. PURCHASE PRICE, ACCEPTABLE FUNDS, DEPOSIT AND
ESCROW OF DEPOSIT

2.1. Purchase Price. The purchase price ("Purchase Price") to be paid by
Buyer to Seller for the Property is Fifteen Million Five Hundred Seventy-Two
Thousand Nine Hundred Thirty-Nine and 70/100 Dollars ($15,572,939.70), subject
to the prorations and adjustments as hereinafter provided in this Agreement.

2.2. Payment of Monies. All monies payable under this Agreement, unless
otherwise specified in this Agreement, shall be paid by wire transfer of
immediately available federal funds.

2.3. Payment of Purchase Price. The Purchase Price, subject to prorations
and adjustments, shall be paid as follows:

(a) Initial Deposit. Seventy-Six Thousand and 00/100 Dollars
($76,000.00) has been paid by Buyer to Seller as a deposit as of the date
of this Agreement (the "Initial Deposit");

(b) Additional Deposit. Thirty-Eight Thousand and 00/100 Dollars
($38,000.00) shall be paid by Buyer to Seller as an additional deposit on
or before the expiration of the Inspection Period (the "Additional
Deposit"); and

(c) Payment at Closing. At the Closing Buyer shall deliver to Escrow
Agent immediately available federal funds in an amount equal to the
Purchase Price less the amount of the Deposit held by the Escrow Agent and
subject to adjustments and apportionments as set forth herein. The Purchase
Price, as adjusted, shall be paid at Closing by wire transfer of
immediately available federal funds, transferred to the order or account of
Seller or such other person as Seller may designate in writing.

2.4. Deposit; Escrow Agent. The Initial Deposit shall be delivered by Buyer
to LandAmerica Title Insurance Corporation (the "Escrow Agent") two (2) business
days after the date of this Agreement. In the event Buyer does not elect to
terminate this Agreement pursuant to Section 6.2 hereof, the Additional Deposit
shall be delivered by Buyer to the Escrow Agent on or before the last day of the
Inspection Period. The Initial Deposit and the Additional Deposit, together with
any interest accrued thereon, are collectively referred to herein as the
"Deposit". Failure of Buyer to so deliver the Initial Deposit and/or the
Additional Deposit on the date specified shall constitute a breach by Buyer of
this Agreement for which the Seller may exercise the remedies set forth in
Section 12.3; provided, Buyer has not previously elected to terminate this
Agreement pursuant to Section 6.2 hereof. Upon receipt from Buyer of the
Deposit, Escrow Agent shall invest the Deposit in an interest-bearing account or
money market fund acceptable to Buyer and Seller and Buyer shall provide its
federal taxpayer identification number to Escrow Agent in connection with such
investment. All interest on the Deposit shall accrue to Buyer, except as
otherwise provided in Section 12.3 hereof. At the Closing, Escrow Agent shall,
at the joint direction of Buyer and Seller release the Deposit to Seller, which
Deposit shall be credited against the balance of the Purchase Price owed by
Buyer to Seller. Escrow Agent shall agree to hold and dispose of the Deposit in
accordance with the terms and provisions of this Agreement.

2.5. Escrow Provisions. Escrow Agent hereby acknowledges receipt by Escrow
Agent of the Initial Deposit paid by Buyer. Escrow Agent agrees to hold, keep
and deliver said Deposit

and all other sums delivered to it pursuant hereto in accordance with the terms
and provisions of this Agreement. Escrow Agent shall not be entitled to any fees
or compensation for its services hereunder. Escrow Agent shall be liable only to
hold said sums and deliver the same to the parties named herein in accordance
with the provisions of this Agreement, it being expressly understood that by
acceptance of this agreement Escrow Agent is acting in the capacity of a
depository only and shall not be liable or responsible to anyone for any
damages, losses or expenses unless same shall have been caused by the gross
negligence or willful malfeasance of Escrow Agent. In the event of any
disagreement between Buyer and Seller resulting in any adverse claims and
demands being made in connection with or for the monies involved herein or
affected hereby, Escrow Agent shall refuse to comply with any such claims or
demands so long as such disagreement may continue; and in so refusing Escrow
Agent shall make no delivery or other disposition of any of the monies then held
by it under the terms of this Agreement, and in so doing Escrow Agent shall not
become liable to anyone for such refusal; and Escrow Agent shall refrain from
acting until (a) the rights of the adverse claimants shall have been finally
adjudicated in a court of competent jurisdiction of the monies involved herein
or affected hereby, or (b) all differences shall have been adjusted by agreement
between Seller and Buyer, and Escrow Agent shall have been notified in writing
of such agreement signed by the parties hereto. Escrow Agent shall not be
required to disburse any of the monies held by it under this Agreement unless in
accordance with a joint written instruction of Buyer and Seller.

Buyer and Seller severally agree to indemnify and hold harmless Escrow
Agent from one half (1/2) of any and all costs, damages and expenses, including
reasonable attorneys' fees, that said Escrow Agent may incur in its compliance
in good faith with the terms of this Agreement; provided, however, this
indemnity shall not extend to any act of gross negligence or willful malfeasance
on the part of the Escrow Agent.

SECTION 3. THE CLOSING

documents necessary for the closing of this transaction pursuant to this
Agreement and the satisfaction of all obligations and conditions precedent to
Closing (the "Closing") shall take place in the offices of Seller's counsel,
▇▇▇▇▇▇▇ ▇▇▇▇ LLP, ▇▇▇ ▇▇▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇▇▇▇, ▇▇▇▇▇▇▇▇▇▇▇▇▇ or such other place

24, 2001 (the "Original Closing Date") or such earlier date or place as Buyer

essence of this Agreement. If Seller shall elect to cure any title or survey
matter under Section 1.2 or Section 1.3, if necessary, the Original Closing Date
shall be extended until fifteen (15) days after the earlier of (a) the
expiration of the thirty (30) day cure period as set forth in said Section 1.2
or Section 1.3, as applicable, or (b) five (5) days after the date Seller
notifies Buyer that such matter has been cured. Notwithstanding anything
contained herein to the contrary, Seller shall have the right to extend the
Closing for up to an additional thirty (30) days by providing notice to Buyer of
such election not less than ten (10) days prior to the Original Closing Date. At
either party's request, the Closing shall be conducted through an escrow

▇▇▇▇▇ ▇. ▇▇▇▇▇, Executive Vice President and Chief Financial Officer of The
Berkshire Group, but without any obligation on his part to make any independent

investigation of the matters being represented and warranted, or to make any
inquiry of any other persons, or to search or examine any files, records, books,
correspondence and the like.

At Closing, Seller shall represent and warrant to Buyer by delivering to
Buyer a certificate (the "Seller's Representation Certificate") certifying that
all representations and warranties of Seller in this Agreement remain true and
correct in all material respects as of the Closing Date and all of the
representations and warranties contained herein shall be deemed remade by Seller
effective as of the Closing Date; provided, however, that to the extent that
Seller becomes aware of any facts or circumstances which would make a
representation or warranty untrue in any material respect, Seller shall promptly
deliver written notice to Buyer of such facts or circumstances after becoming
aware of same (but in no event later than the Closing Date) and, the Seller's
Representation Certificate may be revised at Closing to make exception or
qualification with respect to such matters as may be necessary for such
representations to remain true, but Buyer's agreement to allow such amendment of
Seller's Representation Certificate shall not affect or indicate any waiver of
any condition to Closing set forth in this Agreement, and Buyer may terminate
this Agreement and receive the Deposit, if Seller fails, for any reason, to
deliver Seller's Representation Certificate at Closing without change in any
"material respect" (as defined below), except as to changes which are permitted
or contemplated pursuant to Section 8 hereof.

If Buyer notifies Seller prior to or at the Closing that any representation
or warranty made in Section 5 is not true and correct in any "material respect"
and Seller fails to cure or remedy the same prior to Closing, Buyer may either
(a) except as otherwise set forth in this paragraph, terminate this Agreement
and the Deposit shall be returned to Buyer, and neither party shall have further
rights or obligations pursuant to this Agreement, except for Buyer's obligation
to repair any damage to the Property and to indemnify Seller as set forth in
Section 6.1; or (b) waive any such representation or warranty and close the
transaction without any reduction in the Purchase Price. As used herein,
"material respect" shall mean a cost of in excess of $50,000 applicable to the
Property to cure the damage arising out of a breach of representation and/or
warranty.

If subsequent to Closing Buyer notifies Seller within nine (9) months after
Closing that Buyer discovered post-closing that any representation or warranty
made in Section 5 was not true and correct in any material respect and
specifying the breach with particularity, subject to the limitations set forth
in Section 16.2, Buyer shall have available all remedies at law or in equity as
a consequence thereof. If Buyer does not notify Seller of the breach of any of
its representations and warranties set forth in this Section 5 and institute a
lawsuit therefor in a court of competent jurisdiction within nine (9) months
after the Closing, Buyer shall be deemed to have waived all of its rights to
claim and ▇▇▇ for any breach by Seller of any of its representations and
warranties made in this Section 5.

SECTION 6. INSPECTION PERIOD; ACCESS; PURCHASE "AS IS"

6.1. Buyer's Inspections. During the Inspection Period, Buyer, its agents
and representatives, shall be entitled to enter upon the Property (as
coordinated through Seller's property manager), including all leased areas, upon
at least twenty-four (24) hours prior notice to Seller, to perform inspections
and tests of the Property, including surveys, environmental studies,

examinations and tests of all structural and mechanical systems within the
Improvements, and to examine the books and records and all other documents
relating to the Property in the possession or control of Seller or Seller's
property manager. Buyer shall also have the right to interview Seller's on-site
personnel and vendors. Seller shall have the right to have a representative
present during all times that Buyer, its agents, consultants or representatives
have entered the Property for the purpose of conducting its investigations in
accordance with this Section 6.1. Before entering upon the Property, Buyer shall
furnish to Seller evidence of general liability insurance coverage naming Seller
as an insured with limits of not less than $3,000,000 per occurrence.
Notwithstanding the foregoing, Buyer shall not be permitted to interfere
unreasonably with Seller's operations at the Property or interfere with any
tenant's occupancy at the Property, and the scheduling of any inspections shall
take into account the timing and availability of access to tenants' premises,
pursuant to tenants' rights under the Leases or otherwise. If Buyer wishes to
engage in any testing which will damage or disturb any portion of the Property,
Buyer shall obtain Seller's prior consent thereto, which may be granted, refused
or conditioned in the reasonable discretion of Seller. Without limiting the
generality of the foregoing, Seller's written approval shall be required prior
to any testing or sampling of surface or subsurface soils, surface water,
groundwater or any materials in or about the Property in connection with Buyer's
environmental due diligence. Buyer shall restore the Property to the same
condition as existed prior to such tests or investigations, shall repair any
damage to the Property caused by any such tests or investigations, and shall
indemnify Seller from any and all liabilities, claims, costs and expenses
resulting therefrom or from any breach of any other obligations of Buyer under
this Section 6.1. Buyer and its agents and representatives shall not reveal or
disclose any information obtained during the Inspection Period concerning the
Property or Seller to anyone outside of Buyer's organization, other than its
agents, consultants and representatives unless required by law. The obligations
and indemnification set forth in this Section 6.1 shall survive Closing or the
earlier termination of this Agreement.

6.2. Inspection Period; Buyer Termination Right. The term "Inspection
Period," as used herein, shall mean the period ending on September 24, 2001.
Buyer shall have the right to terminate this Agreement, in its sole discretion,
by giving written notice of such election to Seller on or prior to the final day
of the Inspection Period, in which event the Deposit shall be returned forthwith
to Buyer and, except as expressly set forth herein, neither party shall have any
further liability or obligation to the other hereunder. In the absence of such
written notice, the contingency provided for in this Section 6.2 shall no longer
be applicable, Buyer shall be deemed to have waived any right to terminate
hereunder and this Agreement shall continue in full force and effect. In the
event Buyer timely elects to terminate this Agreement during the Inspection
Period as permitted above, Buyer shall deliver to Seller with Buyer's notice of
termination true, accurate and complete copies of all studies, surveys, plans,
investigations and reports obtained by or prepared by Buyer in connection with
Buyer's inspection of the Property at no cost to Seller.

6.3. "AS IS", "WHERE IS" SALE. EXCEPT AS EXPRESSLY SET FORTH IN THIS
AGREEMENT, IT IS UNDERSTOOD AND AGREED THAT SELLER IS NOT MAKING AND HAS NOT AT
ANY TIME MADE ANY WARRANTIES OR REPRESENTATIONS OF ANY KIND OR CHARACTER,
EXPRESS OR IMPLIED, WITH RESPECT TO THE PROPERTY, INCLUDING, BUT NOT LIMITED TO,
ANY

WARRANTIES OR REPRESENTATIONS AS TO HABITABILITY, MERCHANTABILITY OR FITNESS FOR
A PARTICULAR PURPOSE.

BUYER ACKNOWLEDGES AND AGREES THAT UPON CLOSING SELLER SHALL SELL AND
CONVEY TO BUYER AND BUYER SHALL ACCEPT THE PROPERTY "AS IS, WHERE IS, WITH ALL
FAULTS", EXCEPT TO THE EXTENT EXPRESSLY PROVIDED OTHERWISE IN THIS AGREEMENT.
BUYER HAS NOT RELIED AND WILL NOT RELY ON, AND SELLER IS NOT LIABLE FOR OR BOUND
BY, ANY EXPRESS OR IMPLIED WARRANTIES, GUARANTIES, STATEMENTS, REPRESENTATIONS
OR INFORMATION PERTAINING TO THE PROPERTY OR RELATING THERETO (INCLUDING
SPECIFICALLY, WITHOUT LIMITATION, ANY PROSPECTUS DISTRIBUTED WITH RESPECT TO THE
PROPERTY) MADE OR FURNISHED BY SELLER, THE MANAGERS OF THE PROPERTY, OR ANY REAL
ESTATE BROKER OR AGENT REPRESENTING OR PURPORTING TO REPRESENT SELLER, TO
WHOMEVER MADE OR GIVEN, DIRECTLY OR INDIRECTLY, ORALLY OR IN WRITING, UNLESS
SPECIFICALLY SET FORTH IN THIS AGREEMENT. BUYER ALSO ACKNOWLEDGES THAT THE
PURCHASE PRICE REFLECTS AND TAKES INTO ACCOUNT THAT THE PROPERTY IS BEING SOLD
"AS-IS."

BUYER REPRESENTS TO SELLER THAT BUYER HAS CONDUCTED, OR WILL CONDUCT PRIOR
TO CLOSING, SUCH INVESTIGATIONS OF THE PROPERTY, INCLUDING BUT NOT LIMITED TO,
THE PHYSICAL AND ENVIRONMENTAL CONDITIONS THEREOF, AS BUYER DEEMS NECESSARY OR
DESIRABLE TO SATISFY ITSELF AS TO THE CONDITION OF THE PROPERTY AND THE
EXISTENCE OR NONEXISTENCE OR CURATIVE ACTION TO BE TAKEN WITH RESPECT TO ANY
HAZARDOUS OR TOXIC SUBSTANCES ON OR DISCHARGED FROM THE PROPERTY, AND WILL RELY
SOLELY UPON SAME AND NOT UPON ANY INFORMATION PROVIDED BY OR ON BEHALF OF SELLER
OR ITS AGENTS OR EMPLOYEES WITH RESPECT THERETO, OTHER THAN SUCH REPRESENTATIONS
AND WARRANTIES OF SELLER AS ARE EXPRESSLY SET FORTH IN THIS AGREEMENT. EXCEPT AS
EXPRESSLY SET FORTH IN THIS AGREEMENT, UPON CLOSING, BUYER SHALL ASSUME THE RISK
THAT ADVERSE MATTERS, INCLUDING BUT NOT LIMITED TO, CONSTRUCTION DEFECTS AND
ADVERSE PHYSICAL AND ENVIRONMENTAL CONDITIONS, MAY NOT HAVE BEEN REVEALED BY
BUYER'S INVESTIGATIONS, AND BUYER, UPON CLOSING, SHALL BE DEEMED TO HAVE WAIVED,
RELINQUISHED AND RELEASED SELLER (AND SELLER'S AFFILIATED ENTITIES AND EACH OF
THEIR RESPECTIVE OFFICERS, DIRECTORS, SHAREHOLDERS, EMPLOYEES AND AGENTS
(COLLECTIVELY, "SELLER AFFILIATES")) FROM AND AGAINST ANY AND ALL CLAIMS,
DEMANDS, CAUSES OF ACTION (INCLUDING CAUSES OF ACTION IN TORT), LOSSES, DAMAGES,
LIABILITIES, COSTS AND EXPENSES (INCLUDING REASONABLE ATTORNEYS' FEES) OF ANY
AND EVERY KIND OR CHARACTER, KNOWN OR UNKNOWN, WHICH BUYER MIGHT HAVE ASSERTED
OR ALLEGED AGAINST SELLER (AND SELLER'S OFFICERS, DIRECTORS, SHAREHOLDERS,
EMPLOYEES AND AGENTS) AT ANY TIME BY REASON OF OR ARISING OUT OF ANY LATENT OR
PATENT CONSTRUCTION DEFECTS OR PHYSICAL CONDITIONS, VIOLATIONS OF ANY APPLICABLE
LAWS AND ANY AND

ALL OTHER ACTS, OMISSIONS, EVENTS, CIRCUMSTANCES OR MATTERS REGARDING THE
PROPERTY (COLLECTIVELY, THE "LIABILITIES").

THE PROVISIONS OF THIS SECTION SHALL SURVIVE CLOSING OR ANY TERMINATION OF
THIS AGREEMENT.

6.4. Hazardous Materials. Without limiting the generality of the foregoing
release provisions of this Section 6 and except to the extent Seller has
breached its representation and warranty contained in Section 5.9 hereof, Buyer
waives any rights it may have against Seller or any Seller Affiliates in
connection with any and all Liabilities which arise or which are in any way
related to any Hazardous Materials in, on, above or beneath the Property or
emanating therefrom including, without limitation, under CERCLA (defined below),
and Buyer agrees that it shall not, and irrevocably waives any right it may have
to: (i) implead Seller, (ii) bring a contribution action or similar action
against Seller or (iii) attempt in any way to hold Seller responsible with
respect to any such matter. As used herein, "Hazardous Materials" shall mean and
include, but shall not be limited to any petroleum product and all hazardous or
toxic substances, wastes or substances, any substances which because of their
quantitated concentration, chemical, or active, flammable, explosive,
infectious, radioactive or other characteristics, constitute or may reasonably
be expected to constitute or contribute to a danger or hazard to public health,
safety or welfare or to the environment, including, without limitation, any
hazardous or toxic waste or substances which are included under or regulated
under applicable laws (whether now existing or hereafter enacted or promulgated,
as they may be amended from time to time) including, without limitation, the
Comprehensive Environmental Response, Compensation, and Liability Act of 1980,
42 U.S.C. Section 9601 et seq. ("CERCLA"), the Federal Resource Conservation and
Recovery Act, 42 U.S.C. Section 6901 et seq., and any similar state laws and
regulations adopted thereunder (collectively, "Hazardous Materials Laws"). The
provisions of this Section 6.4 shall survive Closing or any termination of this
Agreement.

6.5. Financial Information. Seller has provided to Buyer certain unaudited
historical financial information regarding the Property relating to certain
periods of time in which Seller owned the Property. Seller makes no
representation or warranty that such material is complete or accurate or that
Buyer will achieve similar financial or other results with respect to the
operations of the Property, it being acknowledged by Buyer that Seller's
operation of the Property and allocations of revenues or expenses may be vastly
different than Buyer may be able to attain. Buyer acknowledges that it is a
sophisticated and experienced purchaser of real estate and further that Buyer
has relied upon its own investigation and inquiry with respect to the operation
of the Property and releases Seller from any liability with respect to such
historical information.

SECTION 7. INSURANCE

7.1. Maintenance of Insurance. Until the Closing, Seller shall maintain its
present insurance on the Property. Subject to the provisions of Section 7.2, the
risk of loss in and to the Property shall remain vested in Seller until the
Closing. Buyer will obtain its own insurance on the Property at Closing.

7.2. Destruction/Condemnation of Property. In the event that all or any
portion of the Land or Improvements is damaged or destroyed by any casualty or
is the subject of a taking or condemnation under the provisions of eminent
domain law after the date hereof but prior to the Closing Date, Seller shall
have no obligation to repair or replace any damage or destruction caused by the
foregoing, but the following shall apply at the Closing: (1) in the event of a
casualty, Buyer shall receive an assignment of the casualty proceeds and a
credit in the amount of any deductible under Seller's insurance policy, and (2)
in the event of a taking, Seller shall assign to Buyer its rights to any
condemnation proceeds resulting from such taking. Notwithstanding the foregoing,
if such casualty or taking is a "Material Event" (as defined below), then Buyer,
at its option, may terminate this Agreement, by written notice to the Seller
given on or before the Closing Date, and upon such termination, the Deposit
shall be returned to Buyer and the parties shall have no further liability or
obligation hereunder, except as otherwise set forth in this Agreement. As used
in this Paragraph, a "Material Event' means either of the following: (a) a
casualty resulting in damage or destruction to the Property, if the cost to
restore the Property to its condition immediately prior to such casualty is
reasonably estimated to exceed $250,000.00; or (b) a taking or condemnation
which would permanently impede access to the Property, reduce available parking
below that required by law, or result in a condemnation award reasonably
estimated to exceed $250,000.00.

SECTION 8. SELLER'S OBLIGATIONS PRIOR TO CLOSING

Seller covenants that between the date of this Agreement and the Closing:

8.1. Leases. Seller shall not after the expiration of the Inspection
Period, without Buyer's prior written consent (which consent shall not be
unreasonably withheld, conditioned or delayed), (a) enter into any new lease for
an apartment unit with a first-time tenant unless the lease is for a period of
not less than six months or not more than one year and the rent shall be not
less than the then current fair market rent for such unit; or (b) enter into,
amend, renew or extend any Lease for an apartment unit with an existing tenant
unless the lease is for a period of not less than six months or not more than
one year and that the rent for the amended, renewal or extension term shall not
be less than the current fair market rent for such unit; or (c) terminate any
Lease except by reason of a default by the tenant thereunder or by reason of the
provisions contained in the Lease; or (d) provide any rebates, rental
concessions, free rent periods, credits or set off under any Lease relating to
any period after Closing. If Buyer fails to reply to Seller's request for
consent in a notice given within five (5) days after Buyer receives such
request, Buyer's consent shall be deemed to have been granted. Prior to the
expiration of the Inspection Period, Seller shall not be required to obtain
Buyer's written consent prior to engaging in any leasing arrangements.

8.2. Continuation of Service Contracts. Seller shall not modify or amend
any Service Contract or enter into any new service contract for the Property
unless the same is terminable without penalty by the then owner of the Property
upon not more than thirty (30) days' notice. If Buyer notifies Seller in writing
on or prior to the expiration of the Inspection Period of any Service Contracts
(the "Terminable Service Contracts") which (a) Buyer does not desire to assume,
and (b) may be terminated as of right by Seller without payment of any
termination fee, Seller shall promptly give notice of termination of each
Terminable Service Contract effective as

of Closing or as of such later date as such Service Contract may first be
terminated without penalty. Otherwise, Buyer shall assume all Service Contracts
at Closing.

8.3. Replacement of Personal Property. No personal property included as
part of the Property shall be removed from the Property unless the same is
replaced with similar items of at least equal quality prior to the Closing.

8.4. Tax Procedure. Seller shall not withdraw, settle or otherwise
compromise any protest or reduction proceeding affecting real estate taxes
assessed against the Property for any fiscal period in which the Closing is to
occur or any subsequent fiscal period without the prior written consent of
Buyer. Real estate tax refunds and credits received after the Closing which are
attributable to the fiscal tax year during which the Closing occurs shall be
apportioned between Seller and Buyer, after deducting the expenses of collection
thereof, based upon the relative time periods each party owns the Property,
which obligation shall survive the Closing.

8.5. Access. Seller shall allow Buyer or Buyer's representatives access to
the Property, the Leases and other documents required to be delivered under this
Agreement upon reasonable prior notice at reasonable times; provided that Buyer
agrees that the original leases and all other original documents shall remain
on-site at the Property.

8.6. Operations. Seller shall manage and maintain the Property in good
operating condition comparable to that existing as of the date hereof, and in
accordance with past practices, normal wear and tear and casualty and
condemnation damage excepted. Seller will perform all current non-structural
maintenance and repairs as may be needed to maintain the Property or as may be
reasonably appropriate to facilitate the leasing of vacant rental space. Seller
will make replacements of items of furniture, fixtures and equipment under the
same circumstances and according to the same standard that such replacements
have been made in the past.

8.7. Rent Ready. Seller shall place any apartments that are vacant as of
the date hereof or which become vacant at least five (5) business days prior to
the Closing Date in a rent ready condition such that they are available for
immediate occupancy. For purposes hereof, "rent ready condition" shall be the
condition that Seller has placed vacant apartments in during its normal course
of business of operating the Property, including, without limitation, operable
kitchen appliances and (if necessary in the reasonable discretion of Seller)
clean carpeting and fresh paint.

SECTION 9. SELLER'S CLOSING OBLIGATIONS

"extended coverage" (deletion of the standard exceptions) under the Buyer's

connection with the transactions set forth herein.

SECTION 11. APPORTIONMENTS AND ADJUSTMENTS TO PURCHASE PRICE

The following apportionments shall be made between the parties at the
Closing as of the close of the business day prior to the Closing:

(a) Buyer shall receive from Seller a credit for any rent and other
income under Leases collected by Seller before Closing that applies to any
period after Closing. Uncollected rent and other uncollected income shall
not be prorated at Closing. After Closing, Buyer shall apply all rent and
income collected by Buyer from a tenant, first to the month in which
Closing occurred, then to such tenant's current monthly rental and then to
arrearages in the reverse order in which they were due, remitting promptly
to Seller, any balance properly allocable to Seller's period of ownership.
Buyer shall ▇▇▇▇ and use commercially reasonable efforts to collect such
rent arrearages in the ordinary course of business, but shall not be
obligated to engage a collection agency or take legal action to collect any
rent arrearages. Commencing ninety (90) days after the Closing, Seller
shall have the right, in its own name, to demand payment of and to collect
rent arrearages 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 expressly exclude the commencement
of eviction proceedings. Buyer agrees to reasonably cooperate with Seller
to collect such rents and to take all steps excluding the commencement of
legal actions, whether before or after the Closing Date, as may be
reasonably necessary to carry out the intention of the foregoing,
including, without limitation, the delivery to Seller, upon demand, of any
relevant books and records (including any 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 action
reasonably necessary for the collection of such rents by Seller;

(b) All security deposits (including pet deposits and interest, if
any) shown on the Rent Roll shall be transferred by Seller to Buyer at
Closing. At the Closing, Buyer shall in writing acknowledge receipt of and
expressly assume all Seller's financial and custodial obligations with
respect to such amounts, it being the intent and purpose of this provision
that, at Closing, to the extent Buyer has received a credit therefor,
Seller will be relieved of all fiduciary and custodial obligations, and
that Buyer will assume all such obligations expressly set forth herein and
be directly accountable to the residents of the Property with respect
thereto;

(c) There shall be no adjustment for wages, vacation pay, pension and
welfare benefits and other fringe benefits of all persons employed by
Seller at the Property, it being the intent of the parties that
simultaneously with the Closing Seller shall terminate any existing
management agreement and Buyer shall have no liability or obligation with
respect to any employee of Seller or its management company prior to
Closing;

(d) Electricity charges, water charges, sewer rents and vault charges,
if any, and other utility charges on the basis of the fiscal period for
which assessed. To the extent possible, as of Closing, Seller shall close
each utility account, retain any utility deposit and arrange for a final
utility reading; otherwise apportionment of utilities at the Closing shall
be based on the last available reading, subject to adjustment after the
Closing on a per diem basis, when the next reading is available;

(e) All general real estate and personal property taxes and other ad
valorem taxes and assessments;

(f) Prepayments paid by Seller under Service Contracts and under any
Terminable Service Contract, to the extent not terminated until after
Closing, shall be paid to Seller at Closing; and

(g) Such other items as are customarily apportioned between sellers
and buyers of real properties of a type similar to the Property and located
in the Garland, Texas area.

If the Closing shall occur before a new tax rate is fixed, the
apportionment of taxes at the Closing shall be upon the basis of the tax rate
for the preceding period applied to the latest assessed valuation. Promptly
after the new tax rate is fixed, the apportionment of taxes shall be recomputed.
Any discrepancy resulting from such recomputation and any errors or omissions in
computing apportionments at the Closing shall be promptly corrected, and payment
made forthwith to the other party, as the case may be, which obligation shall
survive the Closing. If any operating expenses or other prorations cannot
conclusively be determined as of the date of Closing, then the same shall be
adjusted at Closing based upon the most recently issued bills thus far and shall
be re-adjusted within sixty (60) days, or such longer period as may be
necessary, after the Closing occurs. The provisions of this Section 11 shall
survive the Closing.

SECTION 12. FAILURE TO PERFORM

12.1. Buyer's Election. If Seller fails to satisfy all of Seller's
obligations as set forth in this Agreement, Buyer shall have the right to elect,
in its sole discretion, at the Closing, to accept such title as Seller can
deliver to the Property in its then condition and to pay therefor the Purchase
Price without reduction or offset, in which case Seller shall convey such title
for such price.

12.2. Seller's Default. If at the Closing, Seller fails to satisfy all of
Seller's obligations as set forth in this Agreement, and Buyer does not elect to
take title as provided in Section 12.1, Seller shall be in default under this
Agreement and all Deposits made hereunder shall be forthwith returned to Buyer.
Except as set forth in the next succeeding sentence, the return of the Deposit
shall be the sole and exclusive remedy of Buyer for any such Seller default. In
addition to the foregoing, if Buyer desires to purchase the Property in
accordance with the terms of this Agreement and Seller defaults in the
performance of Seller's obligations under Article 9 hereof, Buyer, at its
option, and as Buyer's sole and exclusive remedy, shall have the right to compel
specific performance by Seller hereunder (and, if Buyer is the prevailing party,
Buyer shall be reimbursed for its reasonable attorney's fees) in which event any
Deposit made hereunder shall be delivered to Seller at Closing and credited
against the Purchase Price, provided that in any such specific performance
action Seller shall not be required to undertake any obligations not
specifically set forth in this Agreement or to expend any sums in excess of
those required to be expended in accordance with this Agreement.

12.3. Buyer's Default; Cross-Default. The parties acknowledge that in the
event of Buyer's failure to fulfill its obligations hereunder, it is impossible
to compute exactly the damages which would accrue to Seller. The parties have
taken these facts into account in setting the amount of the Deposit, required
pursuant to Section 2.4, and hereby agree that: (i) such amount is a reasonable
pre-estimate of the damages which would accrue to Seller in the event of

such a Buyer default; (ii) such amount represents damages and not any penalty
against Buyer; and (iii) if this Agreement shall be terminated by Seller by
reason of Buyer's failure to fulfill Buyer's obligations hereunder, the Deposit
together with the interest thereon shall be Seller's sole, full and liquidated
damages in lieu of all other rights and remedies which Seller may have against
Buyer at law or in equity. Notwithstanding any other provision set forth herein,
in the event of a default by Buyer under any of the Other Agreements entitling
Seller to claim the deposit as liquidated damages thereunder, such default shall
be deemed to be a default by Buyer under this Agreement for which Seller shall
be entitled to exercise all of its rights and remedies under this Agreement,
including, without limitation, those set forth in this Section 12.2.

SECTION 13. BROKERAGE FEES

13.1. Brokerage Fees. Seller and Buyer mutually represent and warrant that
LaPaul Partners ("Broker") is the only broker with whom they have dealt in
connection with this Agreement and that neither Seller nor Buyer has dealt with
any other broker in connection with this purchase and sale and that neither
Seller nor Buyer knows of any other broker who has claimed or may have the right
to claim a commission in connection with this purchase and sale. The commission
of the Broker shall be paid by Buyer pursuant to a separate agreement. Seller
and Buyer shall indemnify and defend each other against any costs, claims or
expenses, including attorneys' fees, arising out of the breach on their
respective parts of any representations, warranties or agreements contained in
this Section. The representations and obligations under this Section shall
survive the Closing or, if the Closing does not occur, the termination of this
Agreement.

SECTION 14. NOTICES

14.1. Effective Notices. All notices under this Agreement shall be in
writing and shall be delivered personally or shall be sent by Federal Express or
other comparable overnight delivery courier, addressed as set forth at the
