              (c)  In lieu of receiving the Consideration pursuant to

Limited Partnership Interest ("Units") in the Partnership in exchange for the 
contribution to the Partnership of all or a portion, as the case may be, of 
the Property (such amount being estimated as approximately $1,530,000 worth 
of units (i.e., $6,100,000 - $4,570,000).  Laurel Oak may make such election 
by providing the Partnership written notice no later than thirty (30) days 
prior to the Closing Date.  Such election notice shall state the dollar 
amount of the Consideration to be received in Units.  The number of Units 
issuable in satisfaction of the applicable portion of the Consideration that 
Laurel Oak elects to be so received shall be computed by dividing the 
aggregate dollar amount of such applicable portion of the Consideration by 
the Computed Market Price.  The term "Computed Market Price" shall mean the 
average closing price for the Common Shares as reported by the New York Stock 
Exchange (the "NYSE") for the ten (10) trading day period immediately

Agreement during the initial calendar quarter in which the Closing occurs 
shall be pro-rated by the Partnership based on the number of days the Class A 
Units are outstanding during such quarter.  For example, if the Class A Units 
issuable pursuant to this Agreement are issued on December 1, 1997, each of 
such Class A Units shall be entitled to receive an amount equal to one-third 
of the amount of the distribution payable to a Class A Unit that was 
outstanding during the full quarter.

              (d)  The transaction contemplated by this Agreement is 
conditioned upon the closing of the sale of the other properties identified 
on Exhibit "F" attached hereto (the "Other Properties"), so that no one or 
more of the Other Properties and the Property hereunder may be sold without 
all of the Property being sold unless expressly provided for in writing by 
the parties hereto and in any event the Deposit hereunder and thereunder 
shall be deemed a single deposit for the entire transaction.

         4.   Closing.  The closing of the transactions contemplated by this 
Agreement (the "Closing") shall be held on or before December 12, 1997, but 
in any event no later than fifteen (15) days next following the Due Diligence 
Termination Date, at the offices of the Partnership, Plaza 1000 at Main 
Street, Suite 400, Voorhees, New Jersey, commencing at 10:00 a.m., time being 
of the essence.

         5.   Title And Conveyance Of The Property.

              (a)  At Closing, title to the Real Property shall be insurable 
at regular rates by Commonwealth Land Title Insurance Company (the "Title 
Insurer"), free and clear of all liens, encumbrances and restrictions other 
than the Permitted Exceptions; provided, however, that if title to any of the 
Real Property is not insurable as aforesaid, the Partnership's sole right and 
remedy shall be as set forth in Paragraph 5(b) below.

              (b)  (i)  The Partnership has applied for a title insurance 
commitment (1992 ALTA Form with Creditor's Rights Exclusion Deleted) to be 
issued by the Title Insurer ("Commitment"), agreeing to issue to the 
Partnership, upon recording of the Deeds (as hereinafter defined) for each of 
the Real Property, an owner's policy of title insurance as above specified 
("Title Policy").  Said Commitments shall agree to insure the proposed title 
of the Partnership to each of the Real Property subject only to the Permitted 
Exceptions and such other title exceptions as the Partnership has agreed to 
accept or is deemed to have accepted pursuant to this Paragraph.  If any of 
the Commitments disclose any title exceptions in addition to the Permitted 
Exceptions and the Partnership objects to such additional title exceptions 
(the "Title Defects"), the Partnership shall notify Laurel Oak of such Title 
Defects with sufficient specificity to enable Laurel Oak to respond.  The 
Partnership's notice of any Title Defects shall be given in writing to Laurel 
Oak no later than the date which is five (5) business days prior to the Due 
Diligence Termination Date, together with the Commitments and copies of all 
matters of record raised therein as exceptions thereto, after which the 
Partnership shall be deemed to have waived any and all Title Defects not so 
raised, except for Title Defects which are disclosed to the Partnership in 
continuations of title issued subsequent to the issuance of the Commitments, 
unless the Partnership fails to object to same in writing within three (3) 
business days after the Partnership's receipt of the continuation of title in 
which the same is disclosed, in which case the Partnership will be deemed to 
have waived such additional Title Defects.  Laurel Oak shall have the right, 
but not the obligation (except as otherwise specifically provided), to cure 
such Title Defects and, if Laurel Oak elects to attempt to cure the Title 
Defects but has not cured same on or before the Closing Date, then the 
Closing Date may be extended by Laurel Oak at its sole option for up to 
thirty (30) days to enable Laurel Oak to effect such cure.

                                         -5-



                   (ii) In the event that either (a) Laurel Oak is unable to 
convey title in accordance with the terms of this Agreement, (b) Laurel Oak 
elects not to cure or cause the removal of any exception to title, except as 
required in subparagraph (iii) below, or (c) if Laurel Oak is unable to 
satisfy any other conditions to the Partnership's obligations under this 
Agreement, then (except as otherwise specifically provided in subparagraph 
(iii) below) the sole liability of Laurel Oak shall be to (A) direct the 
Escrow Agent to return the Deposit to the Partnership and (B) reimburse the 
Partnership for the reasonable charges imposed by the Title Company for 
preparation of the Commitments (without the issuance of a policy) and for the 
reasonable fees paid by the Partnership to update the existing surveys 
(collectively "the Partnership's Reasonable Costs"), and upon such payments 
being made, this Agreement shall be deemed canceled and the parties hereto 
shall be released of all obligations and liabilities hereunder, except as to 
any provisions which expressly survive a termination of this Agreement; and 
the Partnership shall have no rights of action against Laurel Oak in law or 
in equity, for damages or, except for the purpose of enforcing Laurel Oak's 
contractual obligations under subparagraph (iii) below, for specific 
performance.  Notwithstanding the foregoing, the Partnership shall have the 
right to waive any conditions to the Partnership's obligations hereunder, in 
which event Laurel Oak shall make the deliveries provided for herein to the 
Partnership to the extent that Laurel Oak is able so to do, and there shall 
be no reduction in the Consideration in such event.

                   (iii)     Notwithstanding the provisions of the foregoing 
paragraph, if the condition of title to the Real Property at the Closing is 
other than that which the Partnership is required or agrees to accept 
hereunder solely by reason of any mortgages or other monetary liens 
(hereinafter referred to as "Liens") which can be satisfied or remedied by 
the payment of a liquidated amount of money not to exceed the Purchase Price, 
Laurel Oak shall not have the right to cancel this Agreement and Laurel Oak 
shall either (aa) discharge, satisfy, or bond the same or (bb) deliver such 
funds to be held in escrow required by the Title Company, in either event so 
that the Title Company shall affirmatively insure the full and complete 
discharge of the foregoing and shall agree to omit the same as an exception 
to its title insurance policy.

                   (iv) Notwithstanding anything to the contrary contained in 
this Agreement, Laurel Oak shall have no duty nor be required to take any 
action, to institute any proceedings or to incur any expense (other than as 
may be expressly required in subparagraph (iii) above) in order to remedy or 
remove any objections to title or otherwise to render title in accordance 
with the terms called for in this Agreement.

              (c)  The Partnership expressly understands, acknowledges and 
agrees that any failure by the Partnership to notify Laurel Oak in writing of 
any Title Defects on or before the expiration of the Due Diligence, shall for 
all purposes be deemed to be an acceptance by the Partnership of such Title 
Defects as if they were one or more of the Permitted Exceptions.  

              (d)  At Closing, Laurel Oak will convey fee simple title to the 
Real Property by a Bargain and Sale Deed with covenant against grantor's acts 
(the "Deed"), subject in all cases to the Permitted Exceptions, in the forms 
attached hereto and made a part hereof as Exhibit "G".

                                         -6-



              (e)  At Closing, Laurel Oak will transfer all of its right, 
title and interest in and to the Personal Property to the Partnership by 
executing a Bill of Sale ("Bill of Sale") in the form attached hereto and 
made a part hereof as Exhibit "H".

              (f)  At Closing, Laurel Oak will assign all of Laurel Oak's 
right, title, and interest, and the Partnership shall assume all of the 
obligations from and after the Closing Date, in, to and under the Leases, 
Licenses and the Contracts for the Property, by executing an Assignment and 
Assumption Agreement in the form attached hereto and made a part hereof as 
Exhibit "I" (the "Assignments").

Partnership shall be obligated (at its own election) to obtain any 
replacement policies. The amounts of all telephone, electric, sewer, water 
and other utility bills, trash removal bills, janitorial and maintenance 
service bills relating to the Property and allocable to the period prior to 
the Closing Date shall be determined and paid by Laurel Oak before Closing, 
if possible, or shall be paid promptly thereafter by Laurel Oak or adjusted

enter into an agreement to such effect at Closing.  Laurel Oak shall attempt

Partnership at Closing and shall receive a full credit for the amount of such 
deposits.  All Contracts and other obligations in connection with the 
Property, to the extent the same are intended to be assumed hereunder, shall 
be prorated as of the Closing Date.

              (b)  Special assessments which have been filed as a lien 
against any of the Real Property on or before the Closing Date and are not 
payable in installments shall be paid by Laurel Oak.  Special assessments 
which have been filed as a lien against any of the Real Property, but which 
are payable in installments shall be adjusted based upon the installment

remaining unpaid assessments shall be assumed by the Partnership.  Special 
assessments which are or may be pending, but which have not become a lien on 
the Real Property as of the Closing Date, and special assessments which are 
filed as a lien after the Closing Date, shall be assumed and paid by the

diem basis.  In addition, any security deposits held by Laurel Oak for any 
Lease, together with the interest due thereon, if any and if required under 
the terms of the Lease or as required by applicable law, shall either be 
credited or transferred to the Partnership at Closing at Laurel Oak's option. 
 If any tenant is in arrears in the payment of rent or additional rent on the 
Closing Date, rents received from such tenant ninety (90) days after the 
Closing Date shall be applied in the following order of priority: (a) to the 
Partnership, so long as 

                                         -10-



such tenant is in arrears for current or prior rent arising after Closing, 
then (b) to Laurel Oak for all rent in arrears prior to the Closing Date; and 
then (c) to the Partnership with no further claim by Laurel Oak thereto.  
Except as herein provided, the Partnership is not under any obligation to 
collect rents in arrears for the benefit of Laurel Oak.  Any rents which are 
delinquent or otherwise not paid at the time of Closing, and collected by the 
Partnership or Laurel Oak within ninety (90) days after Closing shall be 
apportioned as aforesaid and the portion to which Laurel Oak is entitled 
shall be promptly remitted by the Partnership to Laurel Oak.  Laurel Oak 
shall have no claim to rents collected ninety (90) days after the Closing 
Date.  Laurel Oak retains the right to pursue its remedies against Tenants 
after Closing for any delinquent rents or other amounts owed to Laurel Oak 
(other than proceedings to evict Tenant or terminate its lease).  The 
Partnership shall not enter into any agreement pursuant to which any sums 
owed to Laurel Oak in respect of any Lease for periods prior to the Closing 
are reduced, modified or waived.  The Partnership's obligations to collect 
rent arrearages shall be limited to commercially reasonable efforts, and the 
Partnership shall under no circumstance be required to commence litigation 
against any Tenant to collect the same.

Closing Date for any Leases entered into before the date hereof and all 
amendments, renewals and modifications thereof entered into before the date 
hereof, shall be paid by Laurel Oak without contribution by, or reimbursement 
from, the Partnership.  At Closing, the Partnership shall pay or reimburse 
Laurel Oak for any leasing commissions due or to become due prior to Closing 
for any Leases and for any amendments, modifications or renewals of any 
Leases entered into after the date hereof which are entered into in 
accordance with the provisions of Paragraph 15(e) hereof.  The Partnership 
shall expressly assume and be solely obligated to pay all leasing commissions 
payable under all Leases entered into prior to the date hereof (including all 
amendments, renewals and modifications thereof) which are first due or 
payable on or after the Closing Date, regardless of the date on which such 
Leases (including all amendments, renewals and modifications thereof) were 
executed or any of the leasing commissions therefor earned, subject only to 
the Partnership's right to approve any new Leases or amendments, 
discretionary renewals or modifications of any Leases which are not otherwise 
permitted pursuant to Paragraph 15(e), below. Laurel Oak shall be responsible 
for the costs of, and shall pay or perform prior to Closing any tenant 
improvements and allowances for work performed or required to be performed 
(or paid, as applicable) prior to the Closing Date by or on behalf of Laurel 
Oak for all Leases (including all amendments, renewals and modifications 
thereof) entered into on or before the date of this Agreement for any of the 
Real Property.  The Partnership shall assume, pay or reimburse (as 
applicable) Laurel Oak on the Closing Date for  the costs of any tenant 
improvements and allowances for work to first be performed after the Closing 
Date pursuant to Leases (including all amendments, renewals and modifications 
thereof) entered into prior to the date of this Agreement; and  all costs of 
tenant improvements and allowances incurred by or on behalf of Laurel Oak in 
connection with any Leases (including all amendments, renewals and 
modifications thereof) entered into after the date of this Agreement for any 
of the Real Property, provided the same were approved by the Partnership or 
are otherwise permitted as set forth in Paragraph 15(e) hereof and provided 
that such costs are set forth on Exhibit "C" hereto.

                                         -11-



              (f)  Amounts paid or payable as fees or expenses under any of 
the Licenses assigned at Closing, shall be prorated as of the Closing Date 
but all amounts refundable under unassigned and unassignable Licenses shall 
belong to Laurel Oak.

              (g)  Laurel Oak shall be solely responsible for the payment of 
any "roll back taxes" assessed or imposed upon any of the Real Property under 
the "Farmland Assessment Act of 1964," Chapter 58, Laws of 1964, N.J.S.A. 
54:4 23-1 et seq., as amended or otherwise, which relate to any period prior 
to the Closing Date, and Laurel Oak agrees to indemnify, defend and save the 
Partnership harmless (including attorneys' fees) from and against any claim 
for such taxes.

              (h)  Miscellaneous income including, without limitation, 
telephone and vending machine income, if any, shall be prorated as of the 
Closing Date.

              (i)  All of the provisions of this Paragraph 7 and Laurel Oak's 
and the Partnership's respective rights and obligations hereunder shall 
survive the Closing.

         8.   Possession Of Property.

              (a)  Laurel Oak shall deliver possession to the Real Property 
to the Partnership on the Closing Date, subject only to the Permitted 
Exceptions.

              (b)  the Partnership shall assume, by execution of the 
Assignments, all of Laurel Oak's obligations in, to and under the Contracts, 
the Licenses and Leases.  Notwithstanding the foregoing, the Partnership 
shall not assume management, leasing or brokerage agreements provided, 
however, that the Partnership shall remain liable for leasing commissions as 
set forth in Paragraph 7(e), above.

              (c)  All of the provisions of this Paragraph 8 and Laurel Oak's 
and the Partnership's respective rights and obligations hereunder shall 
survive the Closing.

         9.   Representations Of Laurel Oak, the Members and the Partnership.

              (a)  Laurel Oak hereby represents and warrants, as follows, all 
of which shall be true and correct at, and as of, the Effective Date:

                        (1)  Laurel Oak is a limited liability company duly 
organized and validly existing under the laws of the State of New Jersey, and 
is in good standing in such state.

                        (2)  Laurel Oak has all necessary power and authority 
to enter into this Agreement, to perform its obligations hereunder and to 
consummate the transactions contemplated hereby, without the consent or 
authorization of, or notice to, any third party, except those third parties 
to whom such consents or authorizations have been or will be obtained, or to 
whom notices have been or will be given, prior to the Closing.  This 
Agreement constitutes, and the other documents and instruments to be 
delivered by Laurel Oak pursuant 

                                         -12-



hereto when delivered will constitute, the legal, valid and binding 
obligations of Laurel Oak, enforceable against Laurel Oak in accordance with 
their respective terms.

                        (3)  Except as set forth in Exhibit "O" attached 
hereto and made a part hereof, there is no litigation, proceeding or action 
pending or, to the best of Laurel Oak's knowledge, threatened against or 
relating to Laurel Oak or its Property which might materially and adversely 
affect Laurel Oak or its Property or which questions the validity of this 
Agreement or any action taken or to be taken by Laurel Oak pursuant hereto.  
Laurel Oak shall remain responsible to defend, and shall indemnify and hold 
the Partnership harmless from and against all liability, cost and expense 
relating to the litigation identified in on Exhibit "O", which obligation 
shall survive the Closing.  

                        (4)  Neither the execution of this Agreement nor the 
consummation of the transactions contemplated hereby will constitute a 
violation or be in conflict with or constitute a default under any term or 
provision of the Laurel Oak's limited liability agreement or any other 
material agreement, instrument or lease to which Laurel Oak is a party, 
subject to any required consents or authorizations of, or notices to, third 
parties from whom such consents or authorizations will be obtained or to whom 
notices will be given prior to Closing.

                        (5)  True, correct and complete copies of all of the 
following, together with any modifications or amendments thereof, but only if 
and to the extent the same are in Laurel Oak's possession or control, have 
been or will be delivered, or made available, to the Partnership within five 
(5) days following the execution of this Agreement: (i) Leases and rent 
rolls; (ii) Contracts; (iii) leases of equipment, vehicles and other tangible 
personal property used by Laurel Oak in connection with the ownership and 
operation of the Property (the "Personal Property Leases"); (iv) Licenses; 
(v)  surveys; (vi) title reports; (vii) engineering reports; and (viii) 
environmental reports.

                        (6)  To the best of Laurel Oak's knowledge, (i) all 
of the Leases, Contracts and Personal Property Leases and Licenses, are in 
full force and effect, (ii) there has been no action or failure to act by 
Laurel Oak or any other party to any Lease, Contract or Personal Property 
Lease which, with the giving of notice or the passage of time or both, would 
constitute a default in any material respect or otherwise entitle either 
party to damages or a right to terminate; and (iii) Laurel Oak has not 
received from any other party written notice with respect to the condition of 
the Property or the use or repair of the same or of any alleged default by 
Laurel Oak under any such Lease, or Personal Property Lease or License.  
Except as set forth on Exhibit "P", each of the Contracts is terminable at 
will without penalty or cancellation fee upon no more than thirty (30) days 
prior written notice but, except as hereinafter expressly provided, unless 
otherwise directed by the Partnership, the Contracts shall not be terminated 
by Laurel Oak as of Closing.  Anything in this Agreement to the contrary 
notwithstanding, any and all existing management agreements and brokerage or 
leasing agreements shall be terminated as of Closing.  The Partnership shall 
assume all Contracts not terminated at Closing pursuant to the Assignment.

                                         -13-




                        (7)  Laurel Oak shall indemnify and hold the 
Partnership harmless of, from and against any and all claims and liabilities 
arising out of the employment of any individuals by Laurel Oak and its 
affiliates, whether as employees or independent contractors.  As of the 
Closing, there are and shall be no liens against the Real Property arising 
under the Employee Retirement Income Security Act of 1974, as amended, nor 
any other compensation or employment related lien or liability that could 
become the responsibility of the Partnership after the Closing.  The 
Partnership shall be under no obligation to assume any of Laurel Oak's 
employees, it being Laurel Oak's sole responsibility and obligation to 
provide severance arrangements, if any, for all such employees.  This 
Paragraph shall survive Closing.  

                        (8)  To Laurel Oak's actual knowledge, there are no 
public improvements in the nature of off-site improvements or otherwise, 
which have been ordered to be made and/or which have not heretofore been 
assessed and, to Laurel Oak's actual knowledge, there are no special or 
general assessments currently affecting or pending against the Real Property 
or any portion thereof.

                        (9)  Laurel Oak has not been served with written 
notice that it has been named as a party in any litigation, administrative 
proceeding or investigation naming Laurel Oak as a responsible party or 
potentially responsible party for any liability for clean-up costs, natural 
resource damages or other damages or liability for prior disposal or release 
of Hazardous Substances, Hazardous Wastes or other environmental pollutants 
or contaminants. For purposes of this Agreement, "Hazardous Substances" means 
those elements and compounds which are designated as such in Section 101(14) 
of the Comprehensive Response, Compensation and Liability Act (CERCLA), 42 
U.S.C. Section 9601 (14), as amended, all petroleum products and by-products, 
and any other hazardous substances as that term may be further defined in any 
and all applicable federal, state and local laws (including, in New Jersey, 
the New Jersey Industrial Site Recovery Act (ISRA); and "Hazardous Wastes" 
means any hazardous waste, residential or household waste, solid waste, or 
other waste as defined in applicable federal, state and local laws.  Laurel 
Oak has not received any summons, citation, directive, letter or other 
written communication, from any governmental or quasi-governmental authority 
concerning any intentional or unintentional action or omission on Laurel 
Oak's part which either (a) resulted in the releasing, spilling, leaking, 
pumping, pouring, emitting, emptying or dumping of Hazardous Substances or 
Hazardous Wastes, or (b) related in any way to the generation, storage, 
transport, treatment or disposal of Hazardous Substances or Hazardous Wastes.

                        (10) True and correct copies of the income and 
expense statements for the Property, and a current rent roll certified by 
Laurel Oak, will be delivered to the Partnership upon execution of this 
Agreement.

                        (11) Laurel Oak has received no written notice of any 
violation of any of the licenses, permits, consents, authorizations, 
approvals, and certificates of any regulatory, administrative or other 
governmental agency or body, if any, issued to or held by the Laurel Oak and 
related to the ownership or operation of the Property (collectively, the 
"Permits"), and there is no pending or, to the actual knowledge or Laurel 
Oak, threatened 

                                         -14-



proceeding which could result in the revocation or cancellation of, or 
inability of Laurel Oak to renew, any Permit.

                        (12) To the best of Laurel Oak's knowledge, except as 
set forth in Exhibit "Q" attached hereto and made a part hereof, all 
management fees, leasing commissions and tenant improvement allowances are 
fully paid, there are no brokerage commissions owing by Laurel Oak with 
respect to any of the Leases or otherwise related to the Property which have 
not been paid, and there are no ongoing commission or leasing fee obligations.

                        (13) Laurel Oak has received no written notice from 
any insurance company which has issued a policy with respect to the Property 
or by any board of fire underwriters (or other body exercising similar 
functions) claiming any defects or deficiencies or requesting the performance 
of any repairs, alterations or other work, and Laurel Oak will promptly 
notify the Partnership of any such notice or requirement if such notice is 
received prior to the Closing.

                        (14) Laurel Oak is not a "foreign person" and will 
deliver to the Partnership, at the Closing, a statement certifying that it is 
not a "foreign person" within the meaning of the Internal Revenue Code of 
1986, as amended.

                        (15) Laurel Oak has not received written notice from 
any governmental agency or authority of outstanding material violations 
issued by governmental authorities having jurisdiction over the Real Property.

                        (16) Except as may be set forth in a Lease as 
specifically noted on Exhibit "C", there are no options, rights of first 
refusal or conditional sales agreements regarding the purchase and sale of 
the Real Property.

                        (17) There are no oral or written leases or rights of 
occupancy or grants or claims of right, title or interest in any portion of 
the Property other than the leases (the "Leases") listed on the rent roll 
attached hereto as Exhibit "C". No tenant has advised Laurel Oak that Laurel 
Oak is in default under any of the Leases, or asserted any claim or basis for 
any claim for free or reduced rent or right of setoff against the landlord or 
the rent under the Leases, and Laurel Oak and its agent have no actual 
knowledge of any default or any event which has taken place which, with the 
passage of time, or the delivery of notice, or both, could become an event of 
default.  Laurel Oak has the sole right to collect rents under the Leases, 
and neither such right nor any of the Leases has been assigned, pledged, 
hypothecated or otherwise encumbered by Laurel Oak except as additional 
collateral for the existing mortgage upon the Property which shall be 
satisfied at or before Closing.  No holder of any such collateral assignment 
has asserted or exercised any of its right to collect such rents.  Each of 
the Leases is valid and subsisting and in full force and effect, the tenant 
is in actual possession in the normal course, and the rents set forth in 
Exhibit "C" are the actual rents, income and charges being collected by 
Laurel Oak under the Leases.  Any tenant improvements which Laurel Oak is 
obligated to complete pursuant to any Lease (or any unsigned lease proposal 
or lease amendment) has been completed as of this date or shall be completed 
as of Closing, and all costs therefore 

                                         -15-


have been or shall be paid by Laurel Oak, and all of Laurel Oak's work has or 
shall have been accepted by the Tenant without exception on or before 
Closing, other than routine punch list items, which items shall remain the 
responsibility of Laurel Oak following Closing, and which obligation shall 
expressly survive Closing.  The amount of each security deposit contains, 
where required by law or otherwise applicable, interest which has accrued in 
accordance with law.  No tenant of the Property under any of the Leases has, 
and shall not at Closing have, prepaid any rent under any of the Leases for 
more than one (1) month. Except as otherwise set forth on Exhibit "C", no 
security deposits by tenants have heretofore been returned or applied to 
charges against the tenants. 

                        (18) To the best of Laurel Oak's knowledge, the 
Property and the continued operation and use thereof comply with all 
applicable requirements of federal, state and local law, and all applicable 
requirements of governmental bodies or agencies having jurisdiction thereof, 
no portion of the Property lies within a flood hazard area, flood plain or 
wetland; and there are no outstanding notices of any violations issued by 
governmental authority having jurisdiction over the Property. 

                        (19) To the best of Laurel Oak's knowledge, no 
Hazardous Substances (defined below) and no Hazardous Wastes (defined below) 
are present on the Property including, without limitation, asbestos, 
flammable substances, explosives, radioactive materials, hazardous wastes, 
toxic substances, pollutants, pollution, contaminant, polychlorinated 
byphenyls ("PCBs"), urea formaldehyde foam insulation, radon, corrosive, 
irritant, biologically infectious materials, petroleum product, garbage, 
refuse, sludge, hazardous or waste materials, and there has been no use of 
the Property that may, under any federal, state or local environmental 
statute, ordinance or regulation, require, at any time, any closure or 
cessation of the use or occupancy of the Property and/or impose, at any time, 
upon the owner of the Property any clean-up or other monetary obligation.  
Laurel Oak hereby indemnifies and holds the Partnership harmless of, from and 
against any and all liability, loss or damage suffered or incurred as a 
result of a claim, demand, cost or judgment in favor of a third party, 
including, without limitation, any governmental authority, arising from the 
deposit, storage, disposal, burial, dumping, injecting, spilling, leaking, or 
other placement or release in or on the Property of Hazardous Substances or 
Wastes during Laurel Oak's period of ownership.  To the best of Laurel Oak's 
knowledge, neither the Property nor any portion thereof, have been identified 
on the federal CERLIS, the National Priorities List (40 C.F.R. Part 300, App. 
 B) or any state or local list of potential hazardous waste disposal sites or 
as an industrial establishment. Laurel Oak has conducted a complete and 
thorough inspection and test of the underground storage tanks located on the 
Property, if any, and Laurel Oak has confirmed that, to the best of its 
knowledge, the results thereof show compliance with all requirements of the 
Resource Conservation and Recovery Act ("RCRA"), 42 U.S.C. Sections 6901 et 
seq. and all other applicable federal, state and local laws, and Laurel Oak 
has taken all other necessary and appropriate action to comply fully 
therewith. 

                        (20) To the best of Laurel Oak's knowledge, all 
adequate utilities, useable public sanitary and storm sewers, public water 
facilities, electric facilities and, if any, gas facilities (collectively, 
the "Utilities"), are installed in, and are duly connected to, the Real 
Property, the sanitary sewer system has been dedicated to, and accepted by, 
the Municipal 

                                         -16-



Utilities Authority, and can be used without charge except the normal and 
usual metered utility charges and water and sewer charges.  All Utilities 
required for the operation of the Property either enter the Property through 
adjoining public streets or, if they pass through adjoining public land, do 
so in accordance with valid public easements or private easements which will 
inure to the benefit of the Partnership at no cost to the owner of the 
Property.  All of said Utilities are installed and operating and all 
installation, connection and "tap-in" charges have been paid for in full.

                        (21) No work has been performed or is in progress at, 
and no materials have been furnished to the Property which, though not 
presently the subject of, might give rise to construction, mechanic's, 
materialmen's, municipal or other liens against the Property or any portion 
thereof, except that for which full and complete releases have been obtained. 
 If any lien for any such work is filed before or after Closing, Laurel Oak 
shall promptly discharge the same.

                        (22) To the best of Laurel Oak's knowledge, none of 
the artwork being a part of the Personal Property was prepared on a "work for 
hire" basis and none of the artwork was commissioned after 1991.

                        (23) To the best of Laurel Oak's knowledge, all 
applicable charges, fees and assessments (including condominium fees, to the 
extent applicable) and any and all other sums due under declarations, 
cross-easements and like agreements to which the Property or any portion 
thereof may be subject, have been paid, and no special assessments thereunder 
are pending, there is no constituted Board of Directors for the Laurel Oak 
complex, no fees due to such Board, and all consents and approvals required 
to be obtained under any such declarations, cross-easements and like 
agreements have been obtained pursuant to the requirements of such 
documentation. 

                        (24) To the best of Laurel Oak's knowledge, all 
debts, liabilities, and obligations of Laurel Oak arising out of the 
construction, ownership, and operation of the Property including, but not 
limited to, construction costs, salaries, taxes, accounts payable and the 
like, have been paid as they became due and payable and shall continue to be 
so paid from the date hereof until the Closing Date. 

              (b)  Each of Laurel Oak, SS and RRS, on its own behalf, hereby 
represents and warrants as follows, all of which shall be true and correct 
on, and as of, the Effective Date:

                        (1)  That it has received a copy of the Trust's 
Annual Report on Form 10-K, as amended, for the fiscal year ended December 
31, 1996, the Trust's Quarterly Reports on Form 10-Q, as amended, for the 
fiscal quarters ended March 31, 1997, June 30, 1997 and September 30, 1997, 
and all Current Reports on Form 8-K filed by the Trust during fiscal 1997, 
the Trust's proxy statement for its annual meeting of shareholders held on 
May 12, 1997 and a copy of the Partnership Agreement;

                                         -17-



                        (2)  That the Units and the Underlying Shares 
(collectively, the "Securities"), are being acquired for its own account 
without a view to public distribution or resale and that it has no contract, 
undertaking, agreement or arrangement to sell or otherwise transfer or 
dispose of any Securities or any portion thereof to any other person (other 
than from Laurel Oak to the Members);

                        (3)  That it understands that the Securities have not 
been registered under the Securities Act or the securities laws of any state, 
and, as a result thereof, the Securities are "restricted securities" as 
defined in Rule 144 under the Securities Act of 1933, as amended (the 
"Securities Act"), and are subject to substantial restrictions on transfer;

                        (4)  That it understands that the certificates 
evidencing the Securities shall bear a legend indicating that such Securities 
have not been registered under the Securities Act or any applicable state 
securities laws and the transferability thereof is subject to compliance with 
the Securities Act and applicable state securities laws;

                        (5)  That it will not sell or otherwise transfer or 
dispose of any Securities or any portion thereof unless the Securities are 
registered under the Securities Act and any applicable state securities laws 
or it obtains an opinion of counsel which is satisfactory to the Partnership 
or the Trust, as appropriate, that the Securities may be sold in reliance on 
an exemption from such registration requirements, and that the Securities and 
certificates evidencing the same will bear a legend reflecting such 
restrictions;

                        (6)  That it understands that (i) except as expressly 
set forth in the Registration Rights Agreement attached hereto as Exhibit 
"K", neither the Partnership nor the Trust has any obligation or intention to 
register the Securities for resale under any federal or state securities laws 
and (ii) it therefore may be precluded from selling or otherwise transferring 
or disposing of any Securities or any portion thereof for an indefinite 
period of time or at any particular time;

                        (7)  That in determining to acquire the Securities, 
it has relied solely upon its independent investigation, including the advice 
of its legal counsel and accountants or other financial and tax advisers or 
Laurel Oak representatives and has, during the course of discussions 
concerning the acquisition of the Securities, been offered the opportunity to 
ask such questions and inspect such documents concerning the Partnership and 
the Trust and their respective businesses and affairs as it has requested so 
as to more fully understand the nature of the investment and to verify the 
accuracy of the information supplied;

                        (8)  THAT IT UNDERSTANDS THAT THE ACQUISITION OF THE 
SECURITIES INVOLVES A HIGH DEGREE OF RISK, and that it can bear the economic 
risk of the acquisition of the Securities, including the total loss of its 
investment;

                        (9)  That (i) it has adequate means of providing for 
its current needs and financial contingencies, (ii) it has no need for 
liquidity in this investment, (iii) it has no debts or other obligations, and 
cannot reasonably foresee any other circumstances, that 

                                         -18-




are likely in the future to require it to dispose of the Securities, (iv) all 
its investments in and commitments to non-liquid investments are, and after 
its acquisition of the Securities will be, reasonable in relation to its net 
worth and current needs, and (v) it was not formed for the specific purpose 
of making an investment in the Securities;

                        (10) That it understands that no federal or state 
agency has approved or disapproved the Securities, passed upon or endorsed 
the merits of the offering of the Securities hereunder, or made any finding 
or determination as to the fairness of the Securities for investment; and

                        (11) That it understands that the Securities are 
being offered and distributed in reliance on specific exemptions from the 
registration requirements of federal and state securities laws and that each 
of the Partnership and the Trust is relying upon the truth and accuracy of 
the representations, warranties, agreements, acknowledgments and 
understandings set forth herein in order to determine the applicability of 
such exemption and the suitability of Laurel Oak and the Members to acquire 
the Securities.  In this regard, it understands that Common Shares will only 
be issued upon the conversion or redemption of, or otherwise pursuant to, the 
Units, if an exception from the registration requirements of the Securities 
Act is then available for such issuance;

                        (12) It is an accredited investor, as defined in Rule 
501(a) of Regulation D adopted under the Securities Act.

              (c)  It is agreed and understood that the Partnership intends 
to perform its own due diligence, investigation and analysis in connection 
with the transaction contemplated by this Agreement.  If and to the extent 
that the Partnership determines prior to the Due Diligence Termination Date 
that any or all of the representations and warranties made in this Agreement 
by Laurel Oak or the Members shall be untrue as a result of such due 
diligence, investigation or analysis, the Partnership shall not be entitled 
to rely on such representation(s) and warranty(ies) contained in this 
Agreement and the same shall be deemed to have been deleted from this 
Agreement as to such matters. Accordingly, in the event that the Partnership 
has now or hereafter acquires prior to the Due Diligence Termination Date 
actual knowledge that one or more of the representations and warranties of 
Laurel Oak or the Members are not true, no such fact or circumstance known to 
the Partnership shall be made the basis of a claim by the Partnership of a 
breach of representation or warranty by Laurel Oak or a Member, as the case 
may be.  

              (d)  Notwithstanding anything to the contrary contained in this 
Agreement, in the event any representation, agreement or undertaking made by 
Laurel Oak or the Members in this Agreement shall prove to be false and the 
cost or expense incurred or likely to be incurred by the Partnership as a 
result thereof shall not exceed $50,000 in the aggregate, such 
misrepresentation, agreement or undertaking shall be deemed "immaterial" and 
shall not give rise to any right of the Partnership to terminate or refuse to 
close title under this Agreement or give rise to any right of action for 
money damages or specific performance and the Partnership hereby waives all 
its rights, claims and remedies relating thereto.  The Partnership's sole 
remedy in the event any representation, agreement or undertaking of Laurel 
Oak or the Members which is 

                                         -19-



discovered by the Partnership at or prior to the Closing herein shall prove 
to be false and the cost or expense incurred or likely to be incurred by the 
Partnership as a result thereof exceeds $50,000 shall be to terminate this 
Agreement by written notice given at or prior to Closing, which notice shall 
specify in detail the nature of the misrepresentation and identify in detail 
the costs incurred or likely to be incurred by the Partnership, and thereupon 
the Partnership shall receive a refund of the Deposit, and Laurel Oak shall 
reimburse the Partnership for the Partnership's Reasonable Costs and Due 
Diligence Costs.  To the extent the Partnership has actual knowledge that any 
representation, agreement or undertaking is false at or prior to the Closing, 
and does not or is not permitted to terminate this Agreement, the Partnership 
hereby waives all of its rights, claims and remedies relating thereto.

              (e)  The Partnership and the Trust hereby represent and warrant 
as follows, all of which shall be true and correct at, and as of, the 
Effective Date:

                   (1)  The Partnership is a limited partnership duly formed 
and validly existing under the laws of the State of Delaware, and is in good 
standing with the State of Delaware.  The Trust is a real estate investment 
trust duly formed and validly existing under the laws of the State of 
Maryland, and is in good standing with the State Department of Assessments 
and Taxation of Maryland.

                   (2)  Subject to Paragraph 9(e)(5), below, the Partnership 
and the Trust have all necessary power and authority to enter into this 
Agreement, to perform their obligations hereunder, and to consummate the 
transactions contemplated hereby, without the consent or authorization of, or 
notice to, any third party, except those third parties to whom such consents 
or authorizations have been or will be obtained, or to whom notices have been 
or will be given, prior to the Closing.  This Agreement constitutes, and the 
other documents and instruments to be delivered by the Partnership and the 
Trust pursuant hereto when delivered will constitute, the legal, valid and 
binding obligations of the Partnership and the Trust, enforceable against the 
Partnership and the Trust in accordance with their respective terms.

                   (3)  Neither the execution of this Agreement nor the 
consummation of the transactions contemplated hereby will (a) violate any 
provision of any organizational document of the Partnership or the Trust, or 
(b) constitute a violation of or be in conflict with or constitute a default 
under any term or provision of any material agreement, instrument or lease to 
which the Partnership or the Trust is a party.

                   (4)  There is no litigation, proceeding or action pending, 
or, to the best of the Partnership's or the Trust's knowledge, threatened 
against or relating to the Partnership or the Trust which might materially 
and adversely affect the ability of the Partnership or the Trust to 
consummate the transactions contemplated hereby or which questions the 
validity of this Agreement or any action taken or to be taken by the 
Partnership or the Trust pursuant hereto.

                   (5)  The execution and delivery of this Agreement shall 
have been approved by the Board of Trustees of the Trust on or prior to the 
Due Diligence Termination Date and no further action shall thereupon be 
required on the part of the Partnership 

                                         -20-



or the Trust to consummate the transaction contemplated hereby.  The 
signatories for the Partnership and the Trust are authorized and empowered to 
bind the Partnership and the Trust to this Agreement and all transactions 
contemplated herein.

                   (6)  Except as otherwise set forth in Paragraph 9(e)(5) 
above, in connection with the listing application with the NYSE pursuant to 
Paragraph 17(d) and the registration of the Underlying Shares pursuant to the 
Registration Rights Agreement attached hereto as Exhibit "K" and as required 
by any applicable state securities or "blue sky laws", no consent, approval 
or authorization of, or declaration, filing or registration with, any 
governmental agency is required in connection with the execution, delivery 
and performance of this Agreement or the consummation of the transactions 
contemplated hereunder by the Trust or the Partnership.

                   (7)  The Partnership has sufficient funds available to 
consummate the transactions contemplated by this Agreement, without the 
necessity of third-party financing other than other than the Partnership's 
existing revolving credit facility administered by Nationsbank, N.A.  The 
Partnership and the Trust acknowledge that their obligations hereunder are 
not conditioned upon any third party financing or capital infusion by another 
party.

                   (8)  The Securities, upon issuance, if any, will be duly 
and validly issued, fully-paid and non-assessable.

                   (9)  The information contained in the Trust's Annual 
Report on Form 10-K for the year ended December 31, 1996 was prepared in all 
material respects in accordance with and complied in all material respects 
with the requirements of the rules of the Securities and Exchange Commission, 
and did not at the time that it was filed contain any untrue statement of a 
material fact or omit to state a material fact required to be stated therein 
or necessary in order to make the statements therein, in light of the 
circumstances under which they were made, not misleading.

              (f)  As to any representation or warranty made in this 
Agreement which is qualified as being to the best knowledge of the 
Partnership or Laurel Oak, it is agreed and understood that such party shall 
be under no obligation to conduct any independent investigation or inquiry 
regarding the matters covered by such representation and warranty.  The 
Partnership or Laurel Oak will be deemed to have knowledge of a particular 
matter only if the facts and circumstances thereof are actually known to such 
party making such representation or warranty.

              (g)  Each of the representations and warranties set forth in 
this Paragraph 9 shall be deemed renewed by Laurel Oak, the Members and the 
Partnership, as the case may be, on the Closing Date and shall, as a 
condition to each party's obligation to close hereunder, be recertified by 
each party as being true and correct in all material respects as of the 
Closing Date as if made at such time (it being understood that specific, 
numbered representations and warranties that speak of a specified date shall 
only continue to speak as of the date so specified), and all such 
representations shall survive for a period of one year from the Closing.

                                         -21-



         10.  Access To The Property.

              (a)  The Partnership and/or its agents and representatives, 
during normal business hours and after reasonable advance notice to Laurel 
Oak, may enter upon any of the Real Property from time to time prior to the 
Closing Date, accompanied by an agent of Laurel Oak, for purposes of 
conducting such inspections, investigations and/or studies as the Partnership 
deems necessary, including, without limitation, financial reviews, physical 
inspections, lease reviews and environmental reviews and testing, which 
activities may include test borings and soil samplings ("the Partnership's 
Due Diligence Activities").  The Partnership's access to the Real Property 
shall be subject to the rights of the Tenants of any of the Real Property, 
who shall not be unreasonably disturbed during any such inspection by the 
Partnership.  The Partnership shall not engage in any activity in or about 
the Real Property which directly or indirectly violates the terms of any 
governmental or quasi-governmental statute, rule, regulation, order or 
practice.  The Partnership shall not make any physical changes to any of the 
Real Property, except for test borings and soil samplings which shall be 
performed only by licensed engineers reasonably acceptable to Laurel Oak and 
only after three (3) business days' prior notice to Laurel Oak. The 
Partnership may contact any governmental or quasi-governmental authorities 
concerning the Property without the prior written approval of Laurel Oak. 
Laurel Oak shall have the opportunity to observe any and all action taken by 
the Partnership or its representatives, consultants, agents, etc. pursuant to 
this Paragraph 10.  All information set forth in any document which Laurel 
Oak has granted to the Partnership the express right to review, if any, shall 
be held in strict confidence until Closing and thereafter in the event 
Closing does not occur.  If the Partnership violates its obligations under 
this Paragraph 10(a) or in the event of any physical damage to any of the 
Real Property or any Personal Property resulting, directly or indirectly, 
from the exercise by the Partnership of its rights under this Paragraph 
10(a), the Partnership hereby agrees to restore the Real Property and 
Personal Property to their respective conditions prior to incurring such 
damage.  The Partnership hereby agrees to indemnify, defend and hold harmless 
Laurel Oak from and against all physical damage to any of the Real Property 
and Personal Property, personal injury and/or any other claims or liability 
which may occur as a result of the Partnership's (or the Partnership's 
agents, employees, invitees or licensees) entry or activities upon any of the 
Real Property.  The provisions of this Paragraph 10(a) shall survive Closing 
or other termination of this Agreement.

              (b)  The Partnership, or any of the Partnership's consultants 
performing physical tests on the Real Property shall maintain public 
liability insurance policies (naming Laurel Oak as an additional named 
insured with respect to any liability occurring on the Real Property), with 
combined single limit coverage of at least $1,000,000, insuring against 
claims arising as a result of the inspections of the Partnership, its agents, 
employees or such contractors at any of the Real Property.  A certificate of 
insurance evidencing the foregoing coverage shall be delivered to Laurel Oak 
prior to the Partnership's or any of the Partnership's consultants' entry on 
to any of the Real Property.

              (c)  In the event Closing does not occur or this Agreement is 
terminated, the Partnership shall promptly return to Laurel Oak any documents 
obtained from Laurel Oak or Laurel Oak's agents and deliver to Laurel Oak, 
without charge, copies of all 

                                         -22-



written test results, studies, reports and similar materials obtained by or 
on behalf of the Partnership relating to any of the Real Property.

         11.  Due Diligence Period; Additional Provisions.

              (a)  During the period commencing on the Effective Date and 
ending at 5:00 p.m. E.S.T. on the Due Diligence Termination Date, the 
Partnership may, subject to the provisions set forth in Paragraph 10 above, 
review all plans and specifications, condition of title, agreements relating 
to and the availability of utilities, environmental conditions, the physical 
condition of the existing improvements, compliance by the Property with 
zoning, licensing and all other governmental requirements, Leases for any of 
the Real Property, operating statements pertaining to the Property and all 
other aspects and conditions of the Property which the Partnership may decide 
to review (collectively, "the Partnership's Due Diligence Activities"), all 
as the Partnership shall deem appropriate).  In connection with the 
Partnership's Due Diligence Activities, Laurel Oak has delivered or will 
deliver to the Partnership various documents, reports and materials 
(collectively, the "Laurel Oak Due Diligence Materials").  THE PARTNERSHIP 
UNDERSTANDS AND HEREBY ACKNOWLEDGES AND AGREES THAT THE LAUREL OAK DUE 
DILIGENCE MATERIALS ARE BEING DELIVERED TO THE PARTNERSHIP WITHOUT ANY 
REPRESENTATION OR WARRANTY WHATSOEVER BY LAUREL OAK OR BY THE PREPARER OF 
SUCH LAUREL OAK DUE DILIGENCE MATERIALS, WITH THE SOLE EXCEPTION OF ANY 
REPRESENTATION OR WARRANTY AS TO THE CORRECTNESS, ACCURACY OR COMPLETENESS 
THEREOF WHICH IS EXPRESSLY SET FORTH IN THIS AGREEMENT.

              (b)  If, as a result of the Partnership's Due Diligence 
Activities or otherwise, the Partnership shall conclude, for any reason or 
for no reason, that  it does not wish to proceed with the transaction 
contemplated by this Agreement, it may terminate this Agreement by written 
notice delivered to and received by Laurel Oak on or before 5:00 P.M. E.S.T. 
on the Due Diligence Termination Date (as to which date time shall be of the 
essence), with a simultaneous copy thereof to the Escrow Agent.  In the event 
of such timely termination of this Agreement by the Partnership, the Escrow 
Agent shall make the delivery of funds contemplated under Paragraph 1 of the 
Escrow Terms, and this Agreement shall thereupon be null and void and of no 
further force or effect, except as to those matters which expressly survive 
such termination.

              (c)  Laurel Oak shall obtain, prior to the Closing the 
Non-Applicability Letter from the NJDEP or its successor.  In furtherance of 
the foregoing, Laurel Oak shall apply for the Non-Applicability Letter 
promptly after the Effective Date, and shall pursue the same diligently and 
in good faith.

              (d)  The Partnership agrees to prepare and forward to Laurel 
Oak, at the Partnership's sole cost and expense, certificates (the "Estoppel 
Certificates") for execution by the Tenants which shall, at the Partnership's 
election, either (i) be in such form or contain such information as the 
Tenant from whom request is made is obligated under its Lease to execute and 
deliver for execution by the Tenants (the "Required Form"), or (ii) in the 
form annexed hereto as Exhibit "R". Laurel Oak agrees to deliver the Estoppel 
Certificates to the Tenants promptly after the Partnership's written election 
as to the form to be used (which election shall be made not 

                                         -23-



later than five (5) days after the date hereof), and to use all reasonable 
and diligent efforts to obtain executed copies of same from such Tenants 
prior to the Closing.  It shall be a condition to the Partnership's 
obligations hereunder that, at or prior to Closing, Estoppel Certificates 
shall have been obtained from at least 75% of the Tenants at each Property, 
including those identified on Exhibit "S" annexed hereto and made a part 
hereof (the "Identified Tenants"), BUT ONLY IF THE INITIAL REQUEST MADE OF 
SUCH TENANT WAS FOR AN ESTOPPEL CERTIFICATE IN THE REQUIRED FORM, provided, 
however, if an estoppel in the Required Form is not obtained from an 
Identified Tenant, Laurel Oak may, in lieu thereof, deliver its certificate 
containing the information set forth on the Required Form, which certificate 
shall serve as Laurel Oak's representation as to the facts stated therein, 
which representation shall survive for a period of six (6) months following 
the Closing.  In no event shall the Partnership's obligations under this 
Agreement be conditioned, in whole or in part, upon the delivery of Estoppel 
Certificates from any Tenant in other than the Required Form.

         12.  Condemnation.  Laurel Oak covenants and warrants that Laurel 
Oak has not received any written notice of any condemnation proceeding or 
other proceeding in the nature of eminent domain in connection with the Real 
Property, and has no actual knowledge of any threatened condemnation.  As 
used herein, a "material taking" shall mean a taking of either an entire Real 
Property, more than twenty percent (20%) of a Building or more than 10% of 
the parking area of a Real Property.  If, prior to the Closing, any such 
proceeding affecting a material portion of any of the Real Property is 
commenced, Laurel Oak agrees promptly to notify the Partnership thereof.  In 
the event of a material taking of one or more Real Property or commencement 
of proceedings in connection with such a taking, the Partnership may, at its 
sole option exercised by delivery of written notice thereof within ten (10) 
days after receipt of such written notice thereof, (x) proceed to Closing as 
provided in this Paragraph 12 without an abatement of the Consideration and 
at Closing Laurel Oak shall assign to the Partnership, without recourse, all 
condemnation proceeds paid or payable with respect thereto; or (y) terminate 
this Agreement with respect to the Property as to which a material taking has 
occurred, whereupon this Agreement shall terminate with respect to such Real 
Property and this Agreement shall continue in full force and effect with 
respect to all of the remaining Real Property, and at Closing, the 
Partnership shall pay to Laurel Oak the aggregate of the Allocated Prices for 
the remaining Real Property.  Provided the Partnership shall have waived its 
right to terminate this Agreement with respect to the Real Property so taken, 
as provided above, Laurel Oak shall not, from and after the Due Diligence 
Termination Date, settle or adjust any claims relating to a condemnation 
without the Partnership's prior approval, which shall not be unreasonably 
withheld or delayed.

         13.  Damage By Fire Or Other Casualty.

              (a)  Laurel Oak shall promptly notify the Partnership of damage 
to the Improvements occurring by reason of casualty during the period between 
the Effective Date and the Closing Date.  Laurel Oak shall timely notify any 
insurance companies with respect to any damage and shall promptly submit 
claims for such damage.  Provided the Partnership shall have waived its right 
to terminate this Agreement with respect to the Real Property so damaged, as 
provided below, Laurel Oak shall not, from and after the Due Diligence 
Termination Date, settle 

                                         -24-



or adjust any claims relating to a casualty without the Partnership's prior 
approval, which shall not be unreasonably withheld or delayed.

              (b)  If (i) any portion of the Improvements is damaged by fire 
or casualty after the Execution Date and the Improvements so damaged are not 
repaired or restored on or before Closing to substantially the condition 
existing prior to the damage, and (ii) at the time of Closing, the estimated 
cost of repairs by reason of such fire or casualty to the Improvements, as 
determined by an independent adjuster is, with respect to any of the Real 
Property so damaged, an amount equal to or less than ten percent (10%) of the 
Consideration allocated for such Real Property, there shall be no abatement 
or adjustment in the Consideration and, provided the loss or damage is a 
covered loss under Laurel Oak's insurance policy, the Partnership shall be 
required to purchase all of the Real Property in accordance with the terms of 
this Agreement and, at Closing, Laurel Oak shall assign to the Partnership, 
without recourse, all insurance claims and proceeds with respect thereto 
(less sums theretofore expended, if any, by Laurel Oak for emergency repairs 
or barricades) and Laurel Oak shall credit the Partnership at Closing with 
the amount of any applicable deductible.  Laurel Oak shall have no liability 
or obligation with respect to the condition of any of the Real Property as a 
result of any such fire or casualty.  If the repair to, or the restoration 
of, the Improvements so damaged has not been completed as aforesaid and, at 
the time of Closing, the estimated cost of such repair or restoration, as 
determined by such independent adjuster, for any of the Real Property is an 
amount which is greater than ten percent (10%) of the Consideration allocated 
for the applicable Real Property, the Partnership may, at its sole option, 
(x) proceed to Closing as provided in this Paragraph 13(b) without an 
abatement of the Consideration and at Closing Laurel Oak shall assign to the 
Partnership, without recourse, all insurance claims and proceeds with respect 
thereto (less sums theretofore expended, if any, by Laurel Oak for emergency 
repairs or barricades) and Laurel Oak shall credit the Partnership at Closing 
with the amount of any applicable deductible; or (y) terminate this Agreement 
with respect to the Property which have suffered damage to the Improvements 
by fire or other casualty in an amount which exceeds ten percent (10%) of the 
Consideration allocated for such Real Property(s) whereupon this Agreement 
shall terminate with respect to such damaged Real Property(s) and this 
Agreement shall continue in full force and effect with respect to all of the 
remaining Real Property, and at Closing, the Partnership shall pay to Laurel 
Oak the aggregate of the Considerations for the remaining Real Property.  The 
Partnership shall assign all of its right, title and interest in and to any 
and all insurance policies and insurance proceeds relating to such of the 
Real Property for which this Agreement has been terminated.

         14.  Default.

              (a)  If the Partnership shall default in its obligations to pay 
the Consideration and complete Closing in accordance with the terms of this 
Agreement, then, as Laurel Oak's sole and exclusive remedy therefor, Laurel 
Oak shall be entitled to retain the Deposit as liquidated and agreed upon 
damages for the losses and injuries which Laurel Oak shall have sustained and 
suffered as a result of the Partnership's default, and thereupon this 
Agreement and the Partnership's obligations hereunder shall be terminated 
except as expressly provided in this Agreement.  It is agreed that the 
provisions of this Paragraph 14(a) for liquidated and agreed upon damages are 
a bona fide provision for such and are not a penalty, the parties 

                                         -25-



understanding that by reason of the withdrawal of the Real Property from sale 
to the general public at a time when other parties would be interested in 
purchasing such Real Property, that Laurel Oak shall have sustained damages 
which will be substantial, but will not be capable of determination with 
mathematical precision.  Therefore, this provision for liquidated and agreed 
upon damages has been incorporated as part of this Agreement as a provision 
beneficial to both parties.

              (b)  If Laurel Oak shall default in its obligation to deliver 
any of the Deeds or other items described in Paragraph 5 hereof, upon the 
Partnership's (i) tender of the full Consideration and (ii) compliance with 
all of the material terms and conditions of this Agreement, the Partnership 
shall have the sole option of terminating this Agreement and receiving the 
return of the Deposit, together with payment by Laurel Oak of (A) the 
Partnership's Reasonable Costs, and (B) the Partnership's actual, documented 
out-of-pocket costs and expenses incurred in connection with its Due 
Diligence Activity, not to exceed Fifteen Thousand Dollars ($15,000) ("Due 
Diligence Costs") for the Property and the Other Properties or (Y) to seek 
specific performance of Laurel Oak's obligation to convey the Real Property 
in accordance with this Agreement. If the Partnership elects to terminate 
this Agreement, upon payment of the sums described above, Laurel Oak shall be 
released and relieved of any further liability and this Agreement shall 
thereupon be null and void.  Except as expressly set forth above, the 
Partnership hereby waives any right which the Partnership may have to any lis 
pendens or other lien or encumbrance against any of the Real Property, 
equitable relief, consequential or punitive damages, loss of profits, costs 
related to in-house or other overhead allocations, and damages.  The remedies 
set forth herein shall be the Partnership's sole remedies pursuant to this 
Agreement, or otherwise at law or in equity shall become null and void if 
Closing occurs (except as to obligations hereunder which by their terms 
expressly survive Closing), and shall not apply to a defect in title, the 
remedies for which are set forth in Paragraph 5(b) hereof, or to any 
inability on the part of Laurel Oak to perform its obligations under this 
Agreement.

         15.  Operations Prior To Closing.

              (a)  Laurel Oak agrees to operate the Property between the 
Effective Date and the Closing Date in the same general manner as Laurel Oak 
has operated the Property during the immediately preceding six (6) month 
period, paying all costs and expenses as they come due, and in any event 
prior to Closing, and maintaining all insurance coverage currently in force.

              (b)  Laurel Oak shall comply with all of the obligations of 
landlord under the Leases and all other agreements and contractual 
arrangements affecting the Real Property by which Laurel Oak is bound or to 
which the Real Property, or any of them, are subject, and which will be 
binding upon the Partnership or a lien upon such Real Property, after the 
Closing.

              (c)  Laurel Oak shall notify the Partnership promptly of Laurel 
Oak's receipt of any notice from any party alleging that Laurel Oak is in 
default of its obligations under any of the Leases or any Permit or agreement 
affecting the Real Property, or any portion or portions thereof.

                                         -26-



              (d)  No contract for or on behalf of or affecting the Real 
Property shall be negotiated or entered into which cannot be terminated by 
Laurel Oak upon the Closing without the payment of a specific charge, cost, 
penalty or premium for such termination.

              (e)  Except with the prior written consent of the Partnership, 
which the Partnership agrees it shall not unreasonably withhold, condition or 
delay, Laurel Oak shall not enter into any new leases for any portion of the 
Real Property.  Any new lease shall be on the Partnership's customary form 
(which may vary to reflect customary negotiated revisions thereto), or such 
other form which is reasonably acceptable to the Partnership.  Further, 
except with the prior written consent of the Partnership, which the 
Partnership agrees it shall not unreasonably withhold, condition or delay, or 
as set forth above, Laurel Oak shall not amend, extend (except where required 
under the terms of the Lease in question), terminate (except by reason of a 
tenant's default), accept surrender of, or permit any assignments or 
subleases of, any of the Leases (except as may be required under such Lease), 
nor accept any rental more than one (1) month in advance (exclusive of any 
security deposit).

              (f)  Laurel Oak shall not make or permit to be made any capital 
improvements or additions to the Real Property, or any portion thereof, 
without the prior written consent of the Partnership, except those made by 
Laurel Oak pursuant to the express requirements of this Agreement, those made 
by tenants pursuant to the right to do so under their Leases, or by Laurel 
Oak if required by applicable law or ordinance, or as required under any 
Lease.

              (g)  Laurel Oak shall timely bill all tenants for all rent 
billable under Leases, and use commercially reasonable efforts to collect any 
rent in arrears.

              (h)  Laurel Oak shall notify the Partnership of any tax 
assessment disputes (pending or threatened) prior to Closing, and from and 
after the Due Diligence Expiration Date, Laurel Oak not agree to any changes 
in the real estate tax assessment, nor settle, withdraw or otherwise 
compromise any pending claims with respect to tax assessments relating to the 
current or any subsequent year, without the Partnership's prior written 
consent, which shall not be unreasonably withheld, delayed or conditioned.  
If any proceedings shall result in any reduction of assessment and/or tax for 
the tax year in which the Closing occurs, it is agreed that the amount of tax 
savings or refund for such tax year, less the reasonable fees and 
disbursements in connection with such proceedings, shall be apportioned 
between the parties as of the date real estate taxes are apportioned under 
this Agreement.  All refunds relating to any tax year prior to the Closing 
shall be the sole property of Laurel Oak, and all refunds relating to any 
year subsequent to the year in which Closing occurs shall be the sole 
property of the Partnership.  Each party agrees to promptly remit to the 
other any refund received by it which is the property of the other.

              (i)  Laurel Oak shall notify the Partnership promptly of the 
occurrence of any of the following:

                   (i)  Receipt of notice from any governmental or

                                         -27-




quasi-governmental agency or authority or insurance underwriter relating to 
the condition, use or occupancy of the Real Property, or any portion thereof;

                   (ii) Receipt of any notice of default from any tenant or 
from the holder of any lien or security interest in or encumbering the Real 
Property, or any portion thereof;

                   (iii)     Notice of any actual or threatened litigation 
against Laurel Oak or affecting or relating to the Real Property, or any 
portion thereof which may materially and adversely affect the Real Property 
or Laurel Oak's ability to consummate the transactions contemplated by this 
Agreement; or

                   (iv) Vacancy of any demised Property by a tenant, other 
than in accordance with a scheduled lease termination.

agreed that the agents of all parties have participated in the preparation of

         24.  Captions And Recitals.  The captions contained herein are not a

Partnership's Due Diligence Activities and financing purposes, unless the 
Trust is advised by its counsel that applicable securities laws and

Laurel Oak's possession pertaining to the period of Laurel Oak's ownership 
and operation of the Real Property, which information is relevant and

                                         -34-



         36.  Indemnification.

              Without limitation of any other Laurel Oak indemnity 
obligations set forth herein, from and after the Closing Date, Laurel Oak 
shall indemnify, defend and save  and hold harmless the Partnership and the 
Trust, and their respective partners, trustees, directors, officers and 
employees, of, from and against any and all loss, cost, expense, damage, 
claim, and liability, including reasonable attorney's fees and court costs, 
including, without limitation, attorney's fees and costs associated with the 
enforcement of Laurel Oak's indemnification obligations for all claims 
brought within one year of such Closing  (hereinafter collectively, "Losses") 
which the Partnership or the Trust may suffer or incur, resulting from, 
relating to, or arising in whole or in part, from or out of (i) any 
misrepresentation or breach of a representation or warranty by Laurel Oak 
contained in this Agreement; (ii) any failure to fulfill any covenant or 
agreement of Laurel Oak contained in this Agreement; (iii) all litigation set 
forth in this Agreement and on Exhibits hereto; (iv) any and all actions, 
suits, investigations, proceedings, demands, assessments, audits, judgments, 
and/or claims arising out of or relating to any of the foregoing. 

              Promptly after receipt by the Partnership or the Trust of 
written notice of the commencement of any suit, audit, demand, judgment, 
action, investigation or proceeding (a "Third Party Action") or promptly 
after the Partnership or the Trust incurs a Loss or has knowledge of the 
existence of a Loss, the Partnership or the Trust, as the case may be, will, 
if a claim with respect thereto is to be made against Laurel Oak due to 
Laurel Oak's obligation to provide indemnification hereunder, give Laurel Oak 
written notice of such Loss or the commencement of any Third Party Action; 
provided, however, that the failure to provide such notice within a 
reasonable period of time shall not relieve Laurel Oak of any of its 
obligations hereunder.  Promptly after receiving such notice, Laurel Oak 
will, upon notice to the Partnership or the Trust, as the case may be, have 
the right to assume and control the defense and settlement of any such Third 
Party Action at its own cost and expense; provided, however, that it shall be 
a condition precedent to the exercise of such right by Laurel Oak that Laurel 
Oak shall agree in writing that the Loss, or Third Party Action, as the case 
may be, is properly within the scope of the indemnification obligation and 
that as between the parties, Laurel Oak shall be responsible to satisfy and 
discharge such Third Party Action.  Laurel Oak shall not enter into any 
resolution or other compromise of a Third Party Action without obtaining the 
complete release of the Partnership or the Trust, as appropriate, for any 
liability to all claimants under or pursuant to such Third Party Action.  The 
Partnership or the Trust, as the case may be, shall have the right to 
participate in any such defense, contest or other protective action at its 
own cost and expense.  

         Notwithstanding the foregoing, the Partnership or the Trust, as the 
case may be, shall have the right to assume and control the defense and 
settlement of a Third Party Action (a) if such action includes claims for 
equitable relief which, if determined adversely to the Partnership or the 
Trust, as the case may be, could reasonably be expected to interfere with its 
intended business operations or damage its business reputation or (b) if 
Laurel Oak fails to do so in a timely manner.  In any circumstances in which 
the Partnership or the Trust, as the case may be, undertakes to control the 
Third Party Action as provided in this paragraph, it shall (i) not enter into 
any resolution or other compromise involving monetary damages without 
obtaining the prior written consent of Laurel Oak provided that such written 
consent may not be withheld if it would interfere with the Partnership's or 
the Trust's, as the case may be, business operation and 

                                         -35-



(ii) keep Laurel Oak informed on an ongoing basis of the status of such Third 
Party Action and shall deliver to Laurel Oak, copies of all documents related 
to the Third Party Action reasonably requested by Laurel Oak.  The 
Partnership or the Trust, as the case may be, shall act to assure that all
