herein, including the definitions set forth on Exhibit "C."

     NOW THEREFORE, in consideration of the mutual covenants and agreements
contained herein and intending to be legally bound hereby, the parties agree as
follows:

     1.   SALE AND PURCHASE.  Seller hereby agrees to sell and convey to Buyer,
which hereby agrees, subject to the conditions set forth herein, to purchase
from Seller, the Member Interest.




     2.   PURCHASE PRICE.

          (a)  Provided that the Property is generating NOI (as defined below)
equal to at least $351,634.00 at the time of Closing (as defined below), the
purchase price for the Member Interest shall be equal to Three Million Four
Hundred Fifty Thousand Dollars ($3,450,000.00) (the "Purchase Price").  The
Purchase Price shall be paid by the Buyer by delivery of immediately available
wire transfer funds to Seller to such account as shall be designated by Seller.

          (b)  If NOI is less than $351,634.00 at the time of Closing, the
Purchase Price shall be reduced and shall be equal to the NOI at the time of
Closing divided by a capitalization rate of 10.19%, provided, however that in no
event shall Buyer or Seller be obligated to complete Closing hereunder unless
and until NOI has reached $300,000.00. Notwithstanding anything to the contrary
contained in this Agreement, if NOI has not reached $300,000.00 by July 1, 1999

per square foot for the Property.  In computing NOI, credit shall be given for
rental income from Leases in effect at Closing, but under which rent payment has
not commenced as of the Closing Date (the "Open Leases").  The portion of the
Purchase Price based upon such Open Leases (the "Open Lease Holdback") shall be
placed in escrow at Closing with Commonwealth Land Title Insurance Company under
an escrow agreement reasonably acceptable to Seller and Buyer.  The Open Lease
Holdback shall be paid to Seller only to the extent of the portion of the Open
Lease Holdback based upon Open Leases under which rent payment commences within
one hundred twenty (120) days after the Closing Date.  If rent payment does not
commence under any one (1) or more of the Open Leases within one hundred
twenty (120) days after the Closing Date, the portion of the Open Lease Holdback
based upon such Open Leases shall be paid to Buyer.  The term "Leases" shall
mean all leases and other agreements to occupy all or any portion of the
Property executed and in effect on the Contract Date or into which the Company
enters prior to the Closing (as defined below), but pursuant to the express
terms of this Agreement.

connection herewith or at the Closing, the consummation of the transactions
herein contemplated, and

          (d)  PRORATIONS AND ADJUSTMENTS/EXPENSES. To the extent paid for by
the Company (rather than by Tenants under Leases), the following shall be
prorated and adjusted between Seller and Buyer as of the Closing Date:

               (1)  Water, electricity, sewer, gas, telephone and other utility
charges based, to the extent practicable, on final meter readings and final
invoices, or, in the event final readings and invoices are not available, based
on the most currently available billing information, and reprorated upon
issuance of final utility bills;

               (2)  Amounts paid or payable under any Contracts shall be
prorated based, to the extent practicable, on final invoices, or, in the event
final invoices are not available, based on the most currently available billing
information, and reprorated upon issuance of final invoices;

               (3)  All real estate, personal property and ad valorem taxes
applicable to the Property and levied with respect to current tax year shall be
prorated as of the Closing Date, utilizing the actual final Tax Bills.  Prior to
or at the Closing, Seller shall pay or have paid all Tax Bills that are due and
payable prior to or on the Closing Date and shall furnish evidence of such
payment to Buyer and its title company.  Each party's respective obligations to
reprorate real estate taxes shall survive the Closing.

               (4)  All assessments, general or special, shall be prorated as of
the Closing Date on a "due date" basis such that the Seller shall be responsible
for its share of any installments of assessments which are first due or payable
prior to the Closing Date and Buyer shall be responsible for its share of any
installments of assessments which are first due or payable on or after the
Closing Date;

               (5)  Commissions of leasing and rental agents for any Lease
entered into as of or prior to the Contract Date, whether with respect to base
lease term or future expansions, shall be paid in full at or prior to the
Closing by Company, without contribution or proration from Buyer except for
renewal commissions as disclosed to Buyer in the Rent Roll.  As to Leases
entered into between the Contract Date and the Closing Date in accordance with
this Agreement, commissions shall be prorated as of the Closing Date based upon
the portion of the term of the Lease before Closing and the portion of the term
of this Lease after Closing.

               (6)  All Base Rents and other charges, including, without
limitation, all Additional Rent, shall be prorated as of the Closing Date.  At
the time(s) of final calculation and collection from Tenants of Additional Rent
for the calendar year in which Closing is completed, there shall be a
re-proration between Seller and Buyer as to Additional Rent adjustments, with
such re-prorations being payable to the appropriate recipient in cash.  Such
re-proration shall be 


                                          6


paid upon Buyer's presentation of its final accounting to Seller, certified as
to accuracy by Buyer. At the Closing, no "Delinquent Rents" (rents or other
charges that are due as of the Closing) shall be prorated in favor of Seller. 
The parties' respective obligations to reprorate Additional Rent shall survive
the Closing.  Notwithstanding the foregoing, the Company shall use reasonable
efforts after the Closing Date to collect any Delinquent Rents due from Tenants,
but Company shall not be required to sue any Tenants.  All rents and other
charges received by (or for the benefit of) Company from any Tenant after the
Closing shall be first applied against current and past due obligations owed to,
or for the benefit of, Company (with respect to those obligations accruing
subsequent to the Closing Date), and Seller's share of any excess shall be
delivered to Seller, but only to the extent of amounts in default and owed to,
and for the benefit of, Seller for the period prior to the Closing Date.  In no
event, however, shall any sums be paid to Seller to the extent Seller has been
previously reimbursed for such default out of any security deposit and security
deposits have been appropriately prorated hereunder; and

               (7)  Such other items that are customarily prorated in
transactions of this nature shall be ratably prorated.

     For purposes of calculating prorations, Buyer shall be deemed, through
control of the Company, to be in title to the Property, and therefore entitled
to the income therefrom and responsible for the expenses thereof, for the entire
Closing Date.  All such prorations shall be made on the basis of the actual
number of days of the year and month that shall have elapsed as of the Closing
Date.  Bills received after the Closing that relate to expenses incurred,
services performed or other amounts allocable to the period prior to the Closing
Date shall be paid, in cash, by the Company, to the extent due and owing.  Bills
received by the Company or Seller after the Closing Date that relate to expenses
incurred, services performed or other amounts allocable to the period on or
after the Closing Date, shall be paid, in cash, by the Company, to the extent
due and owing.

          (e)  Seller will pay the entire cost of all fees imposed  by its
accountants and attorneys and consultants in connection with this Agreement and
the transaction contemplated hereunder.  Although Seller and Buyer do not
believe that any realty transfer taxes shall be due in connection with the
transfer of the Member Interest, if it is finally determined that transfer taxes
are due and payable, such transfer taxes shall be divided equally by Seller and
Buyer.  Seller and Buyer shall divide equally the cost of contesting such
transfer taxes.  Buyer shall pay all ordinary filing charges and all title
insurance endorsement fees in connection with the transfer of the Member
Interest and issuance of appropriate title endorsements, and all fees imposed by
Buyer's accountants, attorneys, and environmental and engineering consultants.


                                          7

Seller, to perform inspections and tests of the Property, including, but not

"Seller's Deliveries").  Without limitation of the foregoing, Buyer or its
designated independent or other accountants may audit the Operating Statements
(as defined in Exhibit "C" attached hereto), and Seller shall supply such
documentation as Buyer or its accountants may reasonably request in order to
complete such audit.  Notwithstanding anything to the contrary contained in this
Agreement, the effect of any representations, warranties or undertakings made by
Seller in this Agreement shall not be diminished, abrogated, or compromised by
the foregoing inspections, environmental assessments or other tests or
investigations made by Buyer.

          (b)  ENVIRONMENTAL ASSESSMENT.  Buyer or Buyer's agent(s) shall have
the right to employ one or more environmental consultants or other
professional(s) to perform or complete such environmental inspections and
assessments of the Property as Buyer deems necessary or desirable.  Buyer and
its consultants shall also have the right to undertake or complete a technical
review of all documentation, reports, plans, studies and information in
possession or control of the Company or Seller, or its past or present
environmental consultants, concerning or in any way related to the environmental
condition of the Property.  In order to facilitate the assessments and technical
review, Seller shall extend its full cooperation (but without third party
expense to Seller) to Buyer and its environmental consultants, including,
without limitation, providing access to all files and fully and completely
answering all questions.


                                          8


          (c)  BUYER'S UNDERTAKING.  Buyer hereby covenants and agrees that it

the tenancies or business operations of any of the tenants of the Property.  In
the event that, as a result of Buyer's exercise of its rights under Section 4(a)
or Section 4(b), physical damage occurs to the Property, then Buyer shall
promptly repair such damage, at Buyer's sole cost and expense, so as to return

damage.  Buyer hereby indemnifies, protects, defends and holds Seller harmless
from and against any and all losses, damages, claims, causes of action,
judgments, damages, costs and expenses that Seller actually suffers or incurs as
a direct result of any physical damage caused to, in, or at the Property during
the course of, or as a result of, any or all of the studies, investigations and
inspections that Buyer elects to perform (or causes to be performed) pursuant to
this Section 4.

          (d)  CONFIDENTIALITY.  Each party agrees to maintain in confidence,
and not to disclose to tenants or tenants' employees, the information contained

the transactions contemplated by this Agreement; provided, however, that each
party, its agents and representatives may disclose such information and data
(i) to such party's accountants, attorneys, existing or prospective lenders,
investment bankers, accountants, underwriters, ratings agencies, partners,
consultants and other advisors in connection with the transactions contemplated
by this Agreement to the extent that such representatives reasonably need to
know (in the disclosing party's reasonable discretion) such information and data
in order to assist, and perform services on behalf of, the disclosing party;
(ii) to the extent required by any applicable statute, law, regulation or any
Governmental Authority (as defined below) (including, but not limited to,
Form 8-K and other reports and filings required by the SEC and other regulatory
entities, as described in Exhibit "D" attached hereto); (iii) in connection with
any litigation that may arise between the parties in connection with the

          (c)  INDEMNITY.  Notwithstanding anything to the contrary in this
Agreement, with respect to the Property, the Seller and each of Seller's
shareholders (collectively, jointly and severally, "Post Closing Seller") agree
to and do hereby indemnify, defend and hold harmless Buyer, the REIT and each of
their respective partners, shareholders, agents, contractors, employees,
officers, directors, trustees, shareholders, and each of their successors and
assigns (collectively, the "Buyer Indemnified Parties"), from and against any
and all liabilities, claims, demands, suits, administrative proceedings, causes
of action, costs, damages, personal injuries and property damages, losses and
expenses, both known and unknown, present and future, at law or in equity
(collectively, "Losses"), arising out of, by virtue of or related in any way to
an breach by Seller of any of its representations and warranties under
Section 6(b).

     Without limiting any of Post-Closing Seller's above indemnification
obligations, Post-Closing Seller further acknowledges and agrees that its
obligation to indemnify the Buyer Indemnified Parties includes, without
limitation with respect to any breach by the Company or the Seller of its
representations and warranties under Section 6(b):  (i) any and all Remedial
Costs associated with any Tank, Hazardous Material, Hazardous Condition or any
Release; (ii) to the maximum extent allowed by law, all fines and/or penalties
that may be imposed in connection with any Tank or the existence of any
Hazardous Material on, at, under, near, in or about the Property; (iii) the
defense of any claim made by any individual or entity (including any government,
governmental agency or entity) concerning any of the foregoing, which defense
shall be conducted by counsel and with the assistance of environmental advisors
and consultants, in all cases subject to the prior written approval of Buyer;
and (iv) reasonable attorneys' fees and 


                                          14


costs and environmental advisors' and consultants' fees incurred by any of the
Buyer Indemnified Parties with respect to enforcing its rights under this
indemnification provision.  This Section 6 shall survive the Closing for a
period of thirty (30) months.

     7.   TITLE.  At the Closing, Seller agrees that the Company shall have good
and marketable fee simple title to the Property, free and clear of all liens,
claims and encumbrances except for the Permitted Exceptions.  From and after the
date of this Agreement, Company shall not take any action, or fail to take any
action, that would cause title to the Property to be subject to any title
exceptions or objections, other than the Permitted Exceptions.

          (a)  On or before forty-five (45) days after the Contract Date, Buyer
shall furnish Seller with a preliminary title report covering the Property (the
"Title Report") and a written notice specifying those title exceptions which are
not acceptable to Buyer, which objection may include matters shown on any
updated or re-certified survey which Buyer may obtain (the "Disapproved
Exceptions").  Buyer's failure to designate as one of the Disapproved Exceptions
a title exception shown on the Title Report shall constitute Buyer's approval of
such title exception (all title exceptions not designated by Buyer as
Disapproved Exceptions are in this Agreement called "Permitted Exceptions).  The
Seller shall cause the Company to use its best efforts to cause the removal of
all Disapproved Exceptions on or before ten (10) days after Buyer's notice to
Seller of such Disapproved Exceptions, except that liens of an ascertainable
amount and other items which can be removed by the payment of money shall be
paid and discharged by Seller or the Company at or before Closing.  Within such
ten (10) day period, Seller shall notify Buyer of all Disapproved Exceptions
that Seller, after using its best efforts, is unable to remove.  Seller's
failure to give Buyer notice of Seller's inability to remove any Disapproved
Exceptions shall constitute Seller's covenant that such Disapproved Exceptions
shall be removed at or prior to the Closing.  Buyer shall have the rights set
forth in 7(c) if any Disapproved Exceptions cannot be removed by Seller(s) at or
prior to the Closing.

          (b)  It shall be a Condition under this Agreement that the marked-up
Title Reports delivered on the Closing Date shall be in the form described in
this Section 6 and have all standard and general printed exceptions deleted so
as to afford full "extended form coverage," and shall further include an owner's
comprehensive endorsement, an endorsement certifying that the bills for the real
estate taxes pertaining to the Property do not include taxes pertaining to any
other real estate; an access endorsement; a contiguity endorsement, if
applicable; a subdivision or plat act endorsement; a survey endorsement; a
non-imputation endorsement; a Fairway endorsement; and a creditors' rights
endorsement.

          (c)  If Seller or the Company is unable to correct or remove any
Disapproved Exceptions in accordance with the requirements of this Section 7,
Buyer shall have the sole option of either (i) completing the Closing subject to
such Disapproved Exceptions without any abatement of the Purchaser Price, except
that liens of an ascertainable amount and other items which can be removed by
payment of money shall be paid and discharged by Seller or Company prior to
Closing or (ii) being immediately paid Buyer's Reasonable Costs (as defined
below) and, in the latter event, the parties shall be released from all
liability or obligation to the other and this Agreement shall then and
thereafter be null and void.  "Buyer's Reasonable Costs" shall mean all 


                                          15


out-of-pocket costs and expenses incurred by Buyer in connection with this
Agreement and the Property, including, but not limited to, legal fees, title
company charges, engineering fees, environmental consultant's fees, architects'
and surveyors' fees and other similar charges.

          (b)  SELLER'S DELIVERIES.  All of Seller's Deliveries listed on
Exhibit "C" attached hereto and all other items delivered by Seller pursuant to
this Agreement are true, accurate, correct and complete in all material

misleading.  The copies of all documents and other agreements delivered or
furnished and made available by Seller to Buyer pursuant to this Agreement
constitute all of and the only Leases and other agreements relating to or
affecting the ownership and operation of the Property, there being no material
"side" or other agreements, written or oral, in force or effect, to which the
Seller or the Company is a party or to which the Property is subject.

          (c)  DEFAULTS.  Neither the Seller nor the Company is in default under
any of the documents, recorded or unrecorded, referred to in the title

the Property for a retail shopping center, whether required of the Company or
any Tenant.  Without limiting the foregoing, at the time of Closing, the
Property shall comply in all material respects with all applicable requirements
of the Americans With Disabilities Act of 1990 (42 U.S.C.A. Section  12101
ET SEQ.).  The Property is zoned by the municipality in which they are located
so as to permit retail uses and structures thereon, in a manner that
accommodates and is fully compatible with the Improvements.  No zoning,
subdivision, environmental, Hazardous Material, building code, health, fire,
safety or other law, order or regulation is, or, on the Closing Date will be,
violated by the continued maintenance, operation or use of any Improvements or
parking areas in the Property, and no notice of any such violation issued by any
Governmental Authority having jurisdiction over the Property  is outstanding. 
At the time of Closing, all existing streets and other improvements, including
water lines, sewer lines, sidewalks, curbing and streets at each Property shall
have been paid for and either enter the Property through adjoining public
streets, or, if they enter through private lands, do so in accordance with
valid, irrevocable easements running with the ownership of such Property.

          (h)  LITIGATION.  No attachments, execution proceedings, assignments
for the benefit of creditors, insolvency, bankruptcy, reorganization or other
proceedings are pending against the Property, the Company, the Seller, or to the
best of Seller's knowledge, threatened against the Property, the Company or the
Seller, nor are any of such proceedings contemplated by such entities.  In the
event any proceeding of the character described in this Section is initiated or
threatened against the Property, the Company or the Seller prior to the Closing,
Seller shall promptly advise Buyer thereof in writing, the Seller shall remain
responsible therefor, and the Seller shall indemnify, defend and hold Buyer from
any claims, losses, liabilities and expenses (excluding, without limitation,
reasonable counsel fees) relating to any such occurrence.

          (i)  INSURANCE.  The Company now has in force customary and
commercially reasonable amounts of property, liability and business interruption
insurance relating to the Property from established and reputable insurers. 
Neither the Company nor the Seller has received any notice from any insurance
carrier, nor are any of such entities aware of, any defects or inadequacies in
the Property that, if not corrected, would result in termination of insurance
coverage or increase in the normal and customary cost thereof.

          (j)  FINANCIAL INFORMATION.  All Operating Statements (as defined in
Exhibit "C") delivered to Buyer, and all of the Records (as defined in
Exhibit "C") of the Company are complete, accurate, true and correct, in all

          (k)  RE-ZONING.  There is not now pending, and neither Company nor the
Seller has knowledge of, any threatened proceeding for the rezoning of the
Property or any portion thereof, or the taking of any other action by
governmental authorities that would have an adverse impact on the value of the
Property or use thereof.

          (l)  REAL ESTATE TAXES.  True and complete copies of the most recent
real estate "Tax Bill(s)" for (and the only real estate tax bills applicable to)
the Property have been delivered to Buyer.  Neither the Company nor the Seller
has received notice of and does not have any actual knowledge of any proposed
increase in the assessed valuation or rate of taxation of the Property from that
reflected in the most recent Tax Bills.  There is not now pending, and Company
will not, without the prior written consent of Buyer, institute prior to the
Closing Date, any proceeding or application for a reduction in the real estate
tax assessment of the Property or any other relief for any tax year.  There are
no outstanding agreements with attorneys or consultants with respect to the Tax
Bills that will be binding on Buyer or the Property after the Closing.  Other
than the amounts disclosed by the Tax Bills, no other real estate taxes have
been, or will be, assessed against the Property, or any portion thereof, in
respect of the year 1998 or any prior year, and no special assessments of any
kind (special, bond or otherwise) are or have been levied against the Property,
or any portion thereof, that are outstanding or unpaid, and, to the best
knowledge of the Seller, none will be levied prior to the Closing.  The Company
has paid all real estate taxes presently due and owing with respect to the
Property.

          (m)  EASEMENTS AND OTHER AGREEMENTS.  To the knowledge of the Seller,
neither the Company nor the Seller is in default in complying with the terms and
provisions of any of the covenants, conditions, restrictions, rights-of-way or
easements constituting one or more of the Permitted Exceptions.

          (n)  LEASE CONTROVERSIES.  No material controversy, complaint,
negotiation or renegotiation, proceeding, suit or litigation relating to all or
any of the Leases, is pending or, to the knowledge of the Seller or the Company,
threatened, whether in any tribunal or informally.  The Seller is and shall
remain responsible after the Closing Date for defending (or continuing) any such
suit, proceeding or other matter relating to periods prior to the Closing Date,
and all damages, loss, expenses and costs related thereto.

          (o)  CONDEMNATION.  Neither the Seller nor the Company has knowledge
of any pending or contemplated condemnation or other governmental taking
proceedings affecting all or any part of the Property.

          (p)  DISCLOSURE.  No representation or warranty made by Seller
(whether for itself or the Company) in this Agreement, no exhibit attached
hereto with respect to the Property, and no schedule contained in this Agreement
contains any untrue statement of a material fact, or omits to state a material
fact necessary in order to make the statements contained therein not misleading,
or necessary in order to provide a prospective Buyer of the Property with
adequate information as to the Property and its management, operation,
maintenance and repair.  There is no fact known to Seller or the Company which
has, or which could reasonably have been foreseen by Seller or the Company as
likely to have, an adverse effect on the management, 



                                          18

force and effect as if in fact specifically remade at that time.  The
representations and warranties made in this Section 8 shall survive the Closing
for a period of eighteen (18) months.  Notwithstanding anything to the contrary
herein, the effect of the representations and warranties made in this Agreement
by Seller shall not be diminished, abrogated or deemed to be waived by the
inspections, assessments, or any other investigations made by Buyer.

exclusive responsibility for, all expenses due on or before the Closing Date
connected with or arising out of the negotiation, execution and delivery of the
Leases, including, without limitation, brokers' commissions (including those

and recording fees (as well as the cost of all tenant improvements not paid for
by Tenants), and the Seller shall be deemed to have certified and warranted
payment thereof to Buyer at the Closing;

               (10) No Tenant has, by virtue of its Lease or any other agreement
or understanding, any purchase option with respect to the Property, or any
portion thereof, or any right of first refusal to purchase any Property, or a
portion thereof, whether triggered by the transactions contemplated by this
Agreement or by a subsequent sale of the Property or a portion thereof.  No

to, reasonable fees of attorneys of Buyer's choice) and charges which Buyer may
incur, or to which Buyer may become subject, 


                                          20


as a consequence of any breach of the warranties contained in this Section.  The
foregoing indemnity shall survive the Closing for a period of eighteen (18)
months.

     10.  WARRANTIES AND REPRESENTATIONS OF SELLER AS TO MEMBER
INTEREST/SECURITIES AND RELATED MATTERS.  The Seller, for itself and for the
Company, represents and warrants to Buyer that the following matters are true as
of the Contract Date and shall be true as of the Closing Date and covenant as
follows:

          (a)  AUTHORITY.  Seller is duly formed, validly existing, and in good
standing under the laws of Maryland, and has the power and authority to own the
Member Interest.  Seller is a single purpose entity formed for the sole purpose
of being the sole member of the Company. The execution and delivery of this
Agreement by Seller, and the performance of this Agreement by Seller, have been
duly authorized by Seller, and this Agreement is binding on Seller and
enforceable against it in accordance with its terms.  No consent of any
creditor, investor, partner, shareholder, tenant-in-common, judicial or
administrative body, Governmental Authority, or other governmental body or
agency, or other party to such execution, delivery and performance by Seller is
required.  Neither the execution of this Agreement nor the consummation of the
transactions contemplated hereby will (i) result in a breach of, default under,
or acceleration of, any agreement to which the Seller or the Company is a party
or by which the Seller, the Company or the Property is bound; or (ii) violate
any restriction, court order, agreement or other legal obligation to which the
Seller, the Company and/or the Property is subject.

          (b)  COMPANY.  The Company is duly formed, validly existing, and in
good standing under the laws of the State of Maryland, and has the power and
authority to own the Property.  Seller has delivered to Buyer, as part of
Seller's Deliveries, all of the documents relating to the formation or
governance of the Company.  The Company is a single purpose entity, organized
for the sole purpose of owning the Property.

          (c)  MEMBER INTEREST.  Seller owns one hundred percent (100%) of the
Member Interest of the Company.  Seller owns the Member Interest free and clear
of all liens, charges, encumbrances, restrictive agreements and assessments. 
Upon the assignment of the Member Interest to Buyer (or its designee(s)), the
Buyer will receive good and absolute title thereto, free from all liens,
charges, encumbrances, restrictive agreements and assessments whatsoever.  There
are no outstanding rights of first refusal, options, contracts, calls,
commitments or demands of any nature relating to the Member Interest.

          (d)  OPERATING AGREEMENT.  The Operating Agreement of the Company is
in full force and effect, and the Operating Statements include, among other
things, an accurate statement of the Company's financial condition.

          (e)  NO TRANSFERS OF INTERESTS.  There will be no changes in the
composition of the Company or the Seller between the date of this Agreement and
Closing.


                                          21


          (f)  TAX-RELATED ISSUES.

               (1)  The Company is, and at all times has been, properly treated
as a partnership for federal income tax purposes and not as an "association" or
"publicly traded partnership" taxable as a corporation.

               (2)  The Company and the Seller has filed or caused to be filed
in a timely manner (within any applicable extension periods) all tax,
information or other returns required to be filed by the Internal Revue Code of
1986, as amended (the "Code") or by applicable state, or local tax laws
(collectively, "Tax Returns").  Such Tax Returns are true, correct and complete
in all respects; and all federal, state or local income, gross receipts,
license, payroll, employment, excise, severance, stamp, occupation, premium,
unemployment, disability, personal property, sales, use, transfer, registration,
estimated, or other tax of any kind whatsoever, including any interest, penalty
or other addition thereto, whether disputed or not, (collectively, "Taxes") due,
and Taxes due in respect of any person for the Company had an obligation to
withhold and/or otherwise pay over Taxes, have been timely paid in full or will
be timely paid in full by the due date thereof (and whether or not shown on a
Tax Return).  With respect to any taxable year for which a statute of
limitations (or similar provision) has not yet run, none of the Tax Returns of
the Company or the Seller has been audited by a government or taxing authority,
nor is any such audit or other proceeding in process, pending, threatened
(either in writing or verbally, formally or informally) or expected to be
asserted with respect to Taxes (or the collection of Taxes) of the Company or
the Seller, and neither the Company nor the Seller has received notice (either
in writing or verbally, formally or informally) or expects to receive notice
that it has not filed a Tax Return or not paid Taxes required to be filed,
withheld, or paid by it.  The Company and the Seller has disclosed on its
federal income tax returns all positions taken therein that could give rise to a
substantial understatement penalty within the meaning of Code Section 6662.  No
claim has ever been made by an authority in a jurisdiction where the Company or
the Seller does not file Tax Returns that it is or may be subject to taxation by
that jurisdiction.

          (g)  UNITED STATES PERSON. The Company and the Seller are each a
"United States Person" within the meaning of Section 1445(f)(3) of the Code, as
amended, and shall execute and deliver an "Entity Transferor" certification at
Closing.

          (h)  LIABILITIES.  Except for any normal and customary accrued
liabilities and obligations of the Company that are being adjusted at Closing
pursuant to Section 3(d), the Company shall not have any liabilities or
obligations, either accrued, absolute, contingent, or otherwise, which will not
be paid or discharged on or before the Closing Date.  In addition, except for
the claims and liabilities described in the preceding sentence, neither the
Company nor the Seller has received notice of any claim against (or liability
of) the Company or Seller arising from business done, transactions entered into
or other events occurring prior to the Closing Date (and to the best knowledge
of the Seller and the Company, no basis for any such claim or liability exists).


                                          22


          (i)  The representations and warranties in this Section 10 shall be
deemed remade by Seller (for itself and for the Company), as of the Closing Date
with the same force and effect as if in fact specifically remade at that time. 
The representations and warranties made in this Section 10 shall survive the
Closing without time limitation.

     11.  REPRESENTATIONS AND WARRANTIES OF BUYER.  Buyer hereby represents and
warrants to, and covenants with Seller, as follows, which representations,
warranties, and covenants are true, correct and complete on the date of this
Agreement, shall be true, correct, and complete at Closing:

federal court which adversely affect the ability of Buyer to enter into and
perform its obligations under this Agreement

     12.  COVENANTS OF SELLER.  Seller (for itself and for the Company) hereby
covenant with Buyer as follows:

          (a)  NEW LEASES.  The Company shall not amend any Lease or execute any

approval, except for service contracts entered into in the ordinary course of
business that are terminable, without penalty, on not more than 30 days' notice,
for which no consent shall be required.  Neither the Company nor the Seller
shall enter into, or amend, any contract or agreement without the Buyer's
written approval.

          (c)  OPERATING AGREEMENT.  The Operating Agreement of the Company
shall not be amended without Buyer's prior written approval.

otherwise in accordance with applicable laws, ordinances, rules and regulations
affecting the Property.  Without the prior written consent of Buyer, the Company
shall not incur any indebtedness, other that normal and customary current
indebtedness for current payable necessary for the day-to-day operation of  the
Property. 

          (f)  PRE-CLOSING EXPENSES.  Seller has paid or will pay or cause to be
paid in full, prior to the Closing, all bills and invoices for labor, goods,
material and services of any kind relating to the Property and utility charges,
relating to the period prior to the Closing.  Except as the parties may
otherwise agree at or prior to Closing, any alterations, installations,
decorations and other work required to be performed under any and all agreements
affecting the Property have been or will, by the Closing, be completed and paid
for in full.

          (g)  GOOD FAITH.  All actions required pursuant to this Agreement that
are necessary to effectuate the transaction contemplated herein will be taken
promptly and in good faith by the Seller or the Company, as applicable, and
Seller shall furnish Buyer with such documents or further assurances as Buyer
may reasonably require.

          (h)  NO ASSIGNMENT.  After the Contract Date and prior to the Closing,
neither the Company nor the Seller shall assign, alienate, lien, encumber or
otherwise transfer all or any part of any or all of the Member Interest, the
Property or any interest therein.

          (i)  AVAILABILITY OF RECORDS, AUDIT REPRESENTATION LETTER.

               (1)  Upon Buyer's request, for a period of two years after the
Closing, Seller shall (i) make the Records available to Buyer for inspection,
copying and audit by Buyer's designated accountants; and (ii) cooperate with
Buyer (without any third party expense to Seller) in obtaining any and all
permits, licenses, authorizations, and other Governmental Approvals necessary
for the operation of any or all of the Property.  Without limitation of the
foregoing in this Section, Seller agree to abide by the terms of Exhibit "D"
attached hereto.  At any time before or within two years after the Closing,
Seller further agrees to provide to the Buyer's designated independent auditor,
upon request of Buyer or such auditor:  (x) access (to the same extent to which
Buyer would be entitled to such access) to the books and records of the Property
and all related information (including the information listed on Exhibit "D")
regarding the period for which Buyer is required to have the Property audited
under the regulations of the Securities and Exchange Commission, and (y) a
representation letter delivered by each managing agent of the Property regarding
the books and records of the Property, in substantially the form as attached

               (2)  In addition, Seller shall provide, and cooperate, in all
respects, in providing, Buyer with copies of, or access to, such factual
information as may be reasonably requested by Buyer, and in the possession or
control of Seller, to enable the Buyer or the REIT to 


                                          24


issue one or more mutually agreed upon press releases concerning the transaction
that is the subject of this Agreement, to file a Current Report on Form 8-K (as
specified on Exhibit "D"), if, as and when such filing may be required by the
SEC and to make any other filings that may be required by any Governmental
Authority.  The obligation of Seller to cooperate in providing Buyer with such
information for Buyer to file its Current Report on Form 8-K shall survive the
Closing.

          (j)  CHANGE IN CONDITIONS.  Seller shall promptly notify Buyer of any
change in any condition with respect to the Company, the Seller, the Property or
of the occurrence of any event or circumstance that makes any representation or
warranty of Seller to Buyer under this Agreement untrue or misleading, or any
covenant of Buyer under this Agreement incapable or less likely of being
performed, it being understood that Seller's obligation to provide notice to
Buyer under this Section shall in no way relieve Seller of any liability for a
breach by Seller of any of its representations, warranties or covenants under
this Agreement.

          (k)  ENTITY STRUCTURE.  From the Contract Date through and including
the Closing Date, the Company and the Seller shall maintain the same composition

the Property, and (ii) legal deficiencies discovered at or in any Property

including the Closing Date, or if the Seller or the Company fails to perform any
of the covenants and agreements contained herein to be performed by such party
within the time for performance as specified herein (including Seller's
obligation to close), or if any of the Buyer's Conditions Precedent shall not
have been satisfied, Buyer may elect either to (i) terminate Buyer's obligations

retain all rights and remedies available to it; or (ii) close, in which event
Buyer may file an action for either or both of specific performance and damages
to compel Seller to cure all or any of such default(s), in whole or in part,
whereupon Buyer shall be entitled to deduct from the Purchase Price, the cost of
such action and cure, and all reasonable expenses incurred by Buyer in
connection therewith, including, but not limited to, attorneys' fees of Buyer's
counsel.  Notwithstanding anything to the contrary herein and in addition to any
other remedies of Buyer, Buyer shall be entitled to recover actual (but not
consequential) damages suffered by Buyer by reason of Seller's defaults
hereunder and/or any delay occasioned thereby, including, without limitation,
Buyer's Reasonable Costs.  The remedies of Buyer set forth in this Section 15(a)
shall be in addition to remedies otherwise applicable or provided in this
Agreement or otherwise available to Buyer at law or in equity, including,
without limitation, specific performance, it being understood that Buyer's
rights and remedies under this Agreement shall always be non-exclusive and
cumulative and that the exercise of one remedy or form of relief available to
Buyer hereunder shall not be exclusive or constitute a waiver of any other.

hereunder and/or any delay occasioned thereby, including, without limitation,
the reasonable out-of-pocket costs and expenses incurred by Seller in connection
with this Agreement.

default by Seller, whether discovered before or after the Closing or (ii) any
default claim, action or omission arising or alleging to arise under the
Existing Loan Documents and relating to the period prior to the Closing, whether
asserted before or after the Closing.  This indemnification obligation shall

          (e)  BUYER NOTICE AND RIGHT TO CURE.  Anything contained in this
Agreement to the contrary notwithstanding, any thing or act which would
otherwise be a default hereunder by Buyer shall not be a default unless Seller

     18.  NO RECORDING.  This Agreement shall not be recorded in any Clerk's
Office, Recorder's Office or in any office or place of public record.  If Buyer
records this Agreement or causes or permits this Agreement to be recorded, 
Seller may elect to treat such act as a breach of this Agreement and may declare
this Agreement terminated, null and void by recording notice of such termination
in the same records in which this Agreement has been recorded.

     19.  COMMISSIONS.  Seller and Buyer each represents that it has not dealt
with any brokers in connection with this transaction.  Buyer and Seller will
indemnify and defend the other from any and all claims, actual or threatened,
for compensation by any third party by reason of breach of its or their
representation or warranty contained in this Section.  The provisions of this
Section 19 shall survive Closing.

     20.  BINDING EFFECT.  This Agreement shall be binding upon and shall inure

administrators, legal representatives, successors and assigns.

     21.  LITIGATION.  Seller and Buyer waive all rights to a jury trial with
respect to any disputes relating to this Agreement, whether arising before or
after Closing.  In the event of litigation between the parties with respect to
the Property, this Agreement, the performance of their respective obligations
hereunder or the effect of a termination under this Agreement, the losing party
shall pay all costs and expenses incurred by the prevailing party in connection
with such litigation, including, but not limited to, reasonable attorneys' fees
of counsel selected by the prevailing party.  The parties hereby further
acknowledge and agree that in the event of litigation between them, as
contemplated above, and the resolution of that litigation through compromise,
settlement, or partial judgment, the court before which such litigation is
initially brought shall have the right to allocate responsibility, between
Seller and Buyer, for all costs and expenses (including, but not limited to,
attorneys' reasonable fees) incurred by both Seller and Buyer in the pursuit of
that litigation resolved through compromise, settlement or partial judgment. 
Notwithstanding any provision of this Agreement to the contrary, the obligations
of the parties under this Section shall survive termination of this Agreement
and the Closing, if applicable.

     22.  BENEFIT.  This Agreement is for the benefit only of the parties hereto
and their nominees, successors, beneficiaries and assignees as permitted in
Section 24(a) below, above and no other person or entity shall be entitled to
rely hereon, receive any benefit herefrom or enforce against any party hereto
any provision hereof.

     23.  LIMITATION OF LIABILITY.  Upon the Closing, neither the REIT nor 
the Buyer shall assume or undertake to pay, satisfy or discharge any 
liabilities, obligations or commitments of Seller other than those 
specifically agreed to between the parties and set forth in this Agreement.  
Except as otherwise specifically provided in this Agreement, neither the REIT 
nor the Buyer shall assume or discharge any debts, obligations, liabilities 
or commitments of Seller, whether accrued now or hereafter, fixed or 
contingent, known or unknown. Neither the holders of shares 

                                          30


in the REIT, nor the trustees, officers, employees or agents of the REIT shall
be liable under this Agreement and all parties hereto shall look solely to the
REIT assets for the payment of any claim or for the performance of any
obligation of the REIT as a party to this Agreement, both in its own capacity
and in its capacity as a general partner of the Buyer.

     24.  MISCELLANEOUS.

          (a)  BUYER'S RIGHT TO ASSIGN.  Buyer shall have the right to assign
this Agreement, in whole or in part, without the prior consent of Seller, and
upon notice from Buyer, Seller agrees to convey the Member Interest directly to
Buyer's assignee, provided that Buyer and/or such assignee have fulfilled
Buyer's obligations under this Agreement.  Any such assignment shall not relieve
the named Buyer of its obligations under this Agreement through the completion
of Closing under this Agreement.

          (b)  ENTIRE AGREEMENT.  This Agreement and the other agreements
described in this Agreement constitutes the entire understanding between the
parties with respect to the transaction contemplated herein, and all prior or
contemporaneous oral agreements, understandings, representations and statements,
and all prior written agreements, understandings, letters of intent and
proposals are merged into this Agreement.  Neither this Agreement nor any
provisions hereof may be waived, modified, amended, discharged or terminated
except by an instrument in writing signed by the party against which the
enforcement of such waiver, modification, amendment, discharge or termination is
sought, and then only to the extent set forth in such instrument.

          (c)  TIME OF THE ESSENCE.  Time is of the essence of this Agreement. 
If any date herein set forth for the performance of any obligations by Seller or
Buyer or for the delivery of any instrument or notice as herein provided should
be on a Saturday, Sunday or legal holiday, the compliance with such obligations
or delivery shall be deemed acceptable on the next business day following such
Saturday, Sunday or legal holiday.  As used herein, the term "legal holiday"
means any state or federal holiday for which financial institutions or post
offices are generally closed in the Commonwealth of Pennsylvania for observance
thereof.

          (d)  CONDITIONS PRECEDENT.  The obligations of Buyer to pay the
Purchase Price and to close the transaction contemplated herein are subject to
the express Buyer's Conditions Precedent set forth in this Agreement, each of
which is for the sole benefit of Buyer and may be waived at any time by written
notice thereof from Buyer to Seller.  The waiver of any particular Buyer's
Condition Precedent shall not constitute the waiver of any other.

          (e)  CONSTRUCTION.  This Agreement shall not be construed more
strictly against one party than against the other merely by virtue of the fact
that it may have been prepared by counsel for one of the parties, it being
recognized that both Seller and Buyer have contributed substantially and
materially to the preparation of this Agreement.  The headings of various
Sections in this Agreement are for convenience only, and are not to be utilized
in construing the content or meaning of the substantive provisions hereof.


                                          31


          (f)  GOVERNING LAW.  This Agreement shall be governed by, and
construed in accordance with, the laws of the State of Maryland (without giving
effect to the conflict of law rules of that state).

          (g)  PARTIAL INVALIDITY.  The provisions hereof shall be deemed
independent and severable, and the invalidity or partial invalidity or
enforceability of any one provision shall not affect the validity of
enforceability of any other provision hereof.

          (h)  EXPENSES.  Except and to the extent as otherwise expressly
provided to the contrary herein, Buyer and Seller shall each bear its own
respective costs and expenses relating to the transactions contemplated hereby,
including, without limitation, fees and expenses of legal counsel or other
representatives for the services used, hired or connected with the proposed
transactions mentioned above.

          (i)  CONTROL OF DEFENSE COUNSEL.  Each indemnified party shall give
reasonably prompt notice to each indemnifying party of any action or proceeding
commenced against the indemnified party in respect of which indemnity may be
sought hereunder, but failure so to notify an indemnifying party (i) shall not
relieve it from any liability which it may have under any indemnity provided
herein unless and to the extent it did not otherwise learn of such action and
the lack of notice by the indemnified party results in the forfeiture by the
indemnifying party of substantial rights and defenses and (ii) shall not, in any
event, relieve the indemnifying party from any obligations to any indemnified
party hereunder other than its indemnification obligation if the indemnifying
party so elects within a reasonable time after receipt of such notice, the
indemnifying party may assume the defense of such action or proceeding at such
indemnifying party's own expense with counsel chosen by the indemnifying party;
provided, however, that, if such indemnified party or parties reasonably
determine that a conflict of interest exists where it is advisable for such
indemnified party or parties to be represented by separate counsel or that, upon
advice of counsel, there may be legal defenses available to them which are
different from or in addition to those available to the indemnifying party, then
the indemnifying party shall not be entitled to one separate counsel at the
indemnifying party's expense.  If an indemnifying party is not so entitled to
assume the defense of such action or does not assume such defense, after having
received the notice referred to in the first sentence of this Section, the
indemnifying party or parties will pay the reasonable fees and expenses of
counsel for the indemnified party or parties.  In such event however, no
indemnifying party will be liable for any settlement effected without the
written consent of such indemnifying party.  If an indemnifying party is
entitled to assume, and assumes, the defense of such action or proceeding in
accordance with this Section, such indemnifying party shall not be liable for
any fees and expenses of counsel for the indemnified parties incurred thereafter
in connection with such action or proceeding.

          (j)  WAIVER OF CONDITIONS PRECEDENT.  Buyer and Seller shall each have
the right, in its sole and absolute discretion, to waive any Condition Precedent
for its benefit contained in this Agreement.


                                          32


          (k)  COUNTERPARTS.  This Agreement may be executed in any number of
identical counterparts, any of which may contain the signatures of less than all
parties, and all of which together shall constitute a single agreement.

     25.  CALCULATION OF TIME PERIODS.  Notwithstanding anything to the contrary
contained in this Agreement, any period of time provided for in this Agreement
that is intended to expire on or prior to the Closing Date, but that would
extend beyond the Closing Date if permitted to run its full term, shall be
deemed to expire upon the Closing.

     IN WITNESS WHEREOF, Buyer and Seller have executed this Agreement,
intending to be legally bound hereby, as of the date and year first above
written.
