located not more than thirty (30) miles from Boston. The Closing Location Notice
shall contain the notice changing the location of the Closing; the name of the
lender at which such closing shall occur and a street address for the place of

documents required by this Agreement. Buyer and Seller shall deposit all
documents necessary for the Closing in escrow with the Title Company, and Buyer

Title Company and escrow agent, Buyer shall notify Seller of such desire in
writing. Buyer and Seller shall then direct the existing Title Company to wire
the Deposit and any other funds to the new designated Title Company as long as
(a) Buyer pays all fees associated with such transfer and (b) the new designated
Title Company is a nationally recognized company such as Stewart Title Guaranty
Company, Chicago Title Insurance Company, Old Republic Title Insurance Company,
Commonwealth Land Title Corporation or Lawyers Title Company. Upon its receiving
such funds, such new designated Title Company shall be deemed the Title Company
for purposes of this Agreement.

     5.    BUYER'S REVIEW.

           5.1   ACCESS.

                 5.1.1 Seller shall promptly upon the execution hereof make
available to Buyer copies of the Contracts and the Leases. Seller agrees to
allow Buyer or Buyer's agents or representatives reasonable access to the
Property (during business hours) for purposes of any non-intrusive physical or

Contracts, the Leases, Seller's books and records relating to the Property
(other than any privileged, proprietary or confidential records), soil reports,
environmental studies and reports, surveys, building and systems plans, income
and expense statements, and other matters necessary in the reasonable discretion
of Buyer to evaluate and analyze the feasibility of the Property for Buyer's
intended use thereof. Buyer shall not conduct or authorize any physically
intrusive testing of, on, or under the Property without first obtaining Seller's
written consent as to the timing and scope of work to be performed, such consent
not to be unreasonably withheld.

                 5.1.2 Except as otherwise expressly set forth herein, Seller
makes no representations or warranties as to the truth, accuracy, or
completeness of any materials, data, or other information, including without
limitation the contents of Seller's or its property manager's books and records,
marketing materials prepared by Seller or the Broker (as hereinafter defined),
rent rolls or income and expense statements, supplied to Buyer in connection
with Buyer's inspection of the Property. It is the parties' express
understanding and agreement that all such materials are provided by Seller
solely for Buyer's convenience in making its own examination and determination
prior to the Approval Date (as hereinafter defined) as to whether it wishes to
purchase the Property, and, in making such examination and determination, Buyer
shall rely exclusively on its own independent investigation and evaluation of
the Property and not on any materials supplied by Seller.

           5.2   TITLE AND SURVEY. Buyer shall obtain a commitment by the Title
Company to issue an owner's policy of title insurance insuring the Land and the
Improvements (the "Title Commitment"), and a survey of the Land prepared by a

not satisfactory and the curative steps necessary to remove the basis for
Buyer's disapproval. The parties shall then have until the later of ten (10)

agree to satisfy Buyer's objection(s); provided, however, that Seller shall have
no obligation whatsoever to expend or agree to expend any funds, to undertake or
agree to undertake any obligations, or otherwise to attempt to cure or agree to
attempt to cure any objections, and Seller shall not be deemed to have any
obligation to attempt to cure any such matters unless Seller expressly
undertakes such an obligation by a written notice to or written agreement with
Buyer given or entered into on or prior to the Objection Deadline and which
recites that it is in response to an Objection Notice. Buyer's sole right with
respect to any objections contained in an Objection Notice given in a timely
manner shall be to elect on or before the Objection Deadline to terminate this
Agreement pursuant to Section 5.3.2 hereof.

                 5.3.2 BUYER'S RIGHT TO TERMINATE. In the alternative, Buyer

Property by giving Seller written notice of termination (the "Termination
Notice"). If the Termination Notice is timely given, Seller shall direct the
Title Company promptly to return the Deposit to Buyer and neither party shall
have any further obligations or liability hereunder except as expressly set
forth in this Agreement, including without limitation Sections 6.2 and 24
hereof. In the event that Buyer does not tender to Seller the Objection Notice
or the Termination Notice prior to the Approval Date or the Objection Deadline,
as applicable: (a) the Deposit shall be non-refundable; and (b) Buyer shall have
no further rights to the Deposit, and no further right to terminate this
Agreement, except for matters that arise after the Approval Date and prior to

     6.    CONDITION OF PREMISES.

           6.1   Buyer and Seller agree that Buyer is acquiring the Property in

EXPRESS OR IMPLIED. Except as otherwise expressly set forth herein, neither
Seller nor any agents, representatives, or employees of Seller have made any
representations or warranties, direct or indirect, oral or written, express or
implied, to Buyer or any agents, representatives, or employees of Buyer with
respect to the condition of the Property, its fitness for any particular
purpose, or its compliance with any laws, and Buyer is not aware of and does not

inspections made by consultants) as it desires of the Property and all factors
relevant to its use, including, without limitation, the interior, exterior, and
structure of all Improvements, and the condition of soils and subsurfaces

Property to its condition prior to Buyer's inspections. Buyer agrees to
indemnify Seller for all claims or damages arising out of Buyer's inspections,
including, without limitation, claims for personal injury or property damage,
and including all costs and attorneys' fees. The obligations in this Section 6.2

including without limitation pursuant to Sections 5.3.2, 9.1, or 13 hereof.

           6.3   Buyer hereby releases Seller and its agents, representatives,
and employees from any and all claims, demands, and causes of action, past,
present, and future, that Buyer may have relating to (i) the condition of the

operation of the Property, and deliver the Property to Buyer at Closing in its
present condition, normal wear and tear excepted, subject to Section 13 hereof.

           7.2   NEW CONTRACTS. Between the Approval Date and the Date of

necessary to carry out its obligations under Section 7.1.2 and which shall be
cancelable on the earlier to occur of (a) the Closing Date and (b) not more than
thirty (30) days' written notice. If Seller enters into any such Contract, it

seven (7) days thereafter, notifies Seller in writing of Buyer's intention to
assume such Contract, it shall be treated as a non-assumed Contract under
Section 5.5 hereof.

organizational documents of Seller, or any of the terms of any agreement or
instrument to which Seller is a party, or by which Seller is bound, or any

governmental authority or any provision of any applicable order, judgment, or
decree of any court, arbitrator, or governmental authority.

the Property.

           8.2   Buyer represents and warrants to Seller as follows:

                 8.2.1 Buyer is a corporation, duly organized, validly existing,

conflict with or constitute a default under any term or provision of the
organizational documents of Buyer, or any of the terms of provisions of any
agreement or instrument to which it is a party, or by which it is bound, or of
any term of any applicable law, ordinance, rule or regulation of any
governmental authority or of any term of any applicable order, judgment, or
decree of any court, arbitrator, or governmental authority.

           8.3   The above-stated representations and warranties will survive
the Closing for a period of six(6) months, before the expiration of which the
party claiming a breach must have filed an action in a court of competent
jurisdiction, and any representation and warranty not specified in such action
shall expire. Any such claim shall be limited to actual damages (specifically
including reasonable attorneys' fees and expenses and court costs) suffered by
the claiming party (specifically excluding consequential, punitive, or other
damages), and in no event shall the aggregate of such damages exceed $60,000.00.

that the Property has during Seller's ownership thereof always been managed by a
third-party manager, and that Seller has relied upon such manager for knowledge
and notice. The words "to the best of Seller's knowledge" in Section 8.1 mean to
the actual knowledge of Robert Emslie and Scott E. Morrow, the two employees of
Seller who are most familiar with the Property and who have had the most contact
with the management company.

     9.    CONDITIONS PRECEDENT.

           9.1   REPRESENTATIONS AND WARRANTIES. Each party's obligation to
close hereunder shall be conditioned upon the truth in all material respects as
of the Date of Closing of the other party's representations and warranties set
forth in Section 8 hereof. If on the Date of Closing a representation and
warranty is not true, and such representation and warranty either was not true
on the date of this Agreement, or was true on the Date of this Agreement but has
become untrue as a result of a breach of this Agreement by the party making the
representation hereunder, the other party may either seek its remedy pursuant to
Section 18 hereof, waive this condition and proceed to Closing, or terminate
this Agreement by notice to the representing party. If on the Date of Closing a
representation and warranty is not true, and such representation and warranty
was true on the date of this Agreement and has become untrue not as a result of
a breach of this Agreement by the representing party, the other party may either
waive this condition and proceed to Closing or terminate this Agreement by
notice to the representing party. Upon the representing party's receipt of
notice of termination pursuant to this Section 9.1, the Deposit shall be
refunded and this Agreement shall terminate, and neither party shall be liable
to the other for damages or otherwise except as otherwise expressly provided
herein.

           9.2   SELLER'S APPROVALS. Seller's obligation to close hereunder
shall be conditioned upon the approval of this transaction by Seller's internal
committees. If on or before the Approval Date Seller has not notified Buyer that
such approval has been granted, such approval shall be deemed not to have been
granted, and the Deposit shall be refunded and this Agreement shall terminate,
and neither party shall be liable to the other for damages or otherwise except
as otherwise expressly provided herein and except that Seller shall reimburse
Buyer for Buyer's actual, out-of-pocket costs incurred to third parties in
connection with its inspections and due diligence at the Property; provided that
(a) Buyer provides to Seller paid invoices for all such amounts and (b) in no
event shall Seller be obligated to reimburse any amounts in excess of $5,000.00.

           9.3   TENANT ESTOPPEL LETTERS. Buyer's obligation to close hereunder
shall be conditioned upon Buyer's receipt, no later than January 25, 1998
("Estoppel Deadline") of completed tenant estoppel letters, in the form attached
hereto as EXHIBIT 9.3, from three of the four tenants occupying space at the
Property but one of such letters must be from Marlboro Square Liquors (the
"Required Space"). Seller shall direct its management company to send tenant
estoppel letters promptly upon full execution of this Agreement to the tenants
at the Property.

           If on or before the Estoppel Deadline Buyer receives estoppel letters
substantially in the form of EXHIBIT 9.3 covering the Required Space, then this
condition shall be deemed satisfied or waived, and the Closing shall occur as
set forth herein. The term substantially in the form shall mean that the
provisions regarding applicable rent, term and square footage occupied are
completed as well as a statement (which may be qualified to the knowledge of the
tenant) regarding tenant's defaults under the applicable lease is included in
such estoppel letter.

           If on or before the Estoppel Deadline Buyer has not received such
letters covering the Required Space, Buyer may so notify Seller, and upon the
giving of such notice, the Deposit shall be refunded and this Agreement shall
terminate, and neither party shall be liable to the other for damages or
otherwise except as otherwise expressly provided herein. If on or before the
Estoppel Deadline Buyer has not given such notice to Seller, this condition
shall be deemed satisfied and waived, and the Closing shall occur as set forth
herein.

costs and expenses, and all other income, costs, and charges of every kind which
in any manner relate to the operation of the Property (but not including

an official bank cashier's check) by noon, E.S.T., on the Date of Closing, all
prorations shall be made as of the following business day. If the amount of said
taxes, assessments, or rents is not known on the Date of Closing, they shall be
apportioned on the basis of the amounts for the preceding year, with a
reapportionment as soon as the new amounts can be ascertained. If such taxes and
assessments shall thereafter be reduced by abatement, the amount of such
abatement, less the reasonable cost of obtaining the same, shall be apportioned
between the parties, provided that neither party shall be obligated to institute
or prosecute proceedings for an abatement unless otherwise agreed. Buyer shall
be responsible for the payment of any assessments or notice of assessments made
after the date of execution hereof for any public improvement, provided Buyer
takes title hereunder. With respect to security deposits, if any, made by

and promptly remit to Seller rents or other amounts due Seller for the period
prior to Closing, but such best efforts shall not require Buyer to institute
suit to collect such rents. Buyer shall apply all rents or other amounts
received by Buyer, first for the account of Buyer for amounts currently due to
Buyer; second to Seller for any and all amounts due Seller for periods prior to
Closing; and the balance to be retained by Buyer.

Closing either the Improvements are damaged or destroyed, in whole or in part,
by fire or other cause, or any portion of the Land or the Improvements becomes
the subject of a condemnation proceeding by a public or quasi-public authority
having the power of eminent domain, then either (a) the parties shall proceed
with the transaction contemplated herein, in which event Buyer shall be entitled
to receive any insurance proceeds or condemnation awards, or (b) in the event
such damage, destruction, or condemnation involves, in the reasonable estimation
of Seller and Buyer, a loss in an amount in excess of five per cent (5%) of the
Purchase Price, or loss of all or a material portion of access to the Property,
either party, at its option, may terminate this Agreement by notice to the other
within ten (10) days of Buyer's receipt of Seller's notice of such damage or
proceeding, in which case the Deposit shall be refunded, and thereafter neither
party shall have any further obligation or liability to the other by virtue of
this Agreement, except as otherwise expressly provided herein.

     14.   INSURANCE. Seller shall not be obligated to assign to Buyer any fire,
hazard, or liability insurance policies which it holds respecting the Property,
and Seller shall have the right to any and all refunds or rebates resulting from
the termination of such policies.

     15.   BROKER'S COMMISSION. Buyer and Seller each hereby warrants and
represents to the other that it has dealt with no broker or finder in connection
with this transaction except Meredith & Grew, Inc. ("the Broker"), and that it
is not affiliated with the Broker in any way. Buyer and Seller each hereby
agrees to indemnify and hold the other harmless from and against any and all
claims for brokerage or



                                       17
   10
finder's fees or other similar commissions or compensation made by any and all
other brokers or finders claiming to have dealt with the indemnifying party in
connection with this Agreement or the consummation of the transaction
contemplated hereby. The obligations in this Section shall survive the Closing
or the termination of this Agreement for any reason, including without
limitation pursuant to Section 5.3.2, 9.1, or 13 hereof.

     16.   SELLER'S PERFORMANCE. The acceptance and recording of Seller's
Closing Documents by Buyer shall be deemed to be a full performance and
discharge of every agreement and obligation of Seller herein contained and
expressed, except such as are, by the terms hereof, to be performed after the
delivery of said instruments.

     17.   RECORDING PROHIBITED. This Agreement shall not be recorded in any
Registry of Deeds or other office or place of public record. If Buyer shall
record this Agreement or cause or permit the same to be recorded, Seller may, at
its option, elect to treat such act as a default by Buyer under this Agreement.

     18.   REMEDIES.

           18.1  If Seller defaults under this Agreement, Buyer's sole remedy,
at law or in equity, shall be one of either (a) the return of the Deposit to
Buyer, whereupon the obligations of Seller under this Agreement shall terminate;
or (b) the right to obtain specific performance of Seller's obligation to convey
the Property pursuant to this Agreement, provided that in no event shall Seller
be obliged to undertake any of the following: (i) change the condition of the
Property or restore the same after any fire or casualty; (ii) expend money or
post a bond to remove or insure over a title defect or encumbrance or to correct
any matter shown on a survey of the Property; (iii) secure any permit, approval,
or consent with respect to the Property or Seller's conveyance, or (iv) cure
defects objected to by Buyer pursuant to Section 5.3.1 hereof. In no event shall
any officer, director, employee, agent, or representative of Seller have any
personal liability in connection with this Agreement or transaction.

           18.2  If Buyer defaults under this Agreement, the sole remedy of
Seller shall be to retain the Deposit, which sum the parties fix and settle as
liquidated damages for such default of Buyer.

           18.3  Nothing in this Section 18 shall limit the express provisions
of this Agreement obligating one party hereto to indemnify the other or to
restore the Property, including without limitation Sections 6.2 and 24 hereof.

           18.4  In any action to enforce the provisions of this Agreement, the
prevailing party shall be entitled to an award of its attorneys' fees and costs.

     19.   ASSIGNMENT. This Agreement may not be assigned by Buyer without the
express written consent of Seller, which consent Seller may in its sole
discretion withhold, except that Buyer may, without Seller's consent, assign
this Agreement to (a) a limited partnership of which Buyer (or a principal of
Buyer) or any parent or any wholly owned subsidiary of Buyer is the sole general
partner; (b) a limited liability company of which Buyer (or a principal of
Buyer) or any parent or any wholly owned subsidiary of Buyer is the sole manager
or (c) another entity of which Buyer (or a principal of Buyer) is the owner. No
such assignment shall operate to relieve Buyer from any obligation hereunder.

     20.   WAIVER. No waiver of any breach of any agreement or provision
contained herein shall be deemed a waiver of any preceding or succeeding breach
of any other agreement or provision herein contained. No extension of time for
the performance of any obligation or act shall be deemed an extension of time
for the performance of any other obligation or act.

     21.   TIME. It is agreed that time is of the essence of this Agreement.

     22.   GOVERNING LAW. This Agreement shall be construed under the laws of
the state in which the Property is located.
