responsible for funding of all of the allowances payable to Motorola, Inc. as
tenant under the Lease as reflected in Section 4.C. of the Lease, to the extent
                                       -----------

               2.1.7. Potential Adjustment For Reduction In Assumed Lease
Obligations. The Purchase Price has been reduced from $34,150,000 to $33,735,656
predicated upon the Purchaser's assuming and performing the obligations set
forth in Section 58.B. of the Lease, and the parties' agreement that the net
present value of the aggregate amount of such obligation is $414,344 (such
obligation being to reimburse the Tenant under the Lease in respect of certain
rent payments required of it under its prior lease as therein described). The
agreed upon net present value was determined by discounting the five monthly
payments of $84,952 therein described at 10% per annum. If, and to the extent,
the actual payments made by Purchaser in respect of such obligation are less
than $84,952 per month or are for a period less than that specified in Section
58.B. of the Lease (being from November 1, 2000 to March 31, 2001), then
Purchaser shall make a payment to Seller increasing the Purchase Price to the
amount it would have been had the actual amount paid by it had been so
discounted to its present value and deducted from $34,150,000. Not later than
April 15, 2001, Purchaser shall provide to Seller a written statement certifying
the amount it has paid in respect of the obligations assumed under Section 58.B.
of the Lease, and if such amount is less than the aggregate obligation
contemplated under such Section , Purchaser shall also concurrently remit to
Seller the amount described in this Section 2.1.7. The provisions of this
Section 2.1.7. shall survive Closing.

deliver the Earnest Money to the party hereto entitled to same pursuant to the

Escrow Agent and the non-terminating party of written notice of such termination
from the terminating party, unless the other party hereto notifies Escrow Agent
that it disputes the right of the other party to receive the Earnest Money. In
such event, Escrow Agent may interplead the Earnest Money into a court of
competent jurisdiction in the county in which the Earnest Money has been
deposited. All attorneys' fees and costs and Escrow Agent's costs and expenses
incurred in connection with such interpleader shall be assessed against the
party that is not awarded the Earnest Money, or if the Earnest Money is
distributed in part to both parties, then in the inverse proportion of such
distribution.

     4.11 Purchaser's Agreement to Indemnify. Purchaser indemnifies and holds
Seller and Asset Manager harmless from and against any and all liens, claims,
causes of action, damages, liabilities and expenses (including reasonable
attorneys' fees) arising out of Purchaser's inspections or tests permitted under
this Agreement or any violation of the provisions of Sections 4.3, 4.8 and 4.10;
                                                     --------------------------
provided, however, the indemnity shall not extend to protect Seller from any
pre-existing liabilities for matters merely discovered by Purchaser (i.e.,
latent environmental contamination) so long as Purchaser's actions do not
aggravate any pre-existing liability of Seller. Purchaser also indemnifies and
holds any tenant harmless from and against any and all claims, causes of action,
damages, liabilities and expenses which such tenant may suffer or incur due to
Purchaser's breach of its obligation under Section 4.8 above to maintain the
                                           -----------
confidential nature of any Property Documents or other information relative to
such tenant. Purchaser's obligations under this Section 4.11 shall survive the

     4.12 Environmental Studies; Seller's Right to Terminate. As additional
consideration for the transaction contemplated in this Agreement, Purchaser must
provide to Seller, immediately following the receipt of same by Purchaser,
copies of any and all reports, tests or studies involving contamination of or
other environmental concerns relating to the Property; provided, however,
Purchaser shall have no obligation to cause any such tests or studies to be
performed on the Property. Seller acknowledges that Purchaser has not made and
does not make any warranty or representation regarding the truth or accuracy of
any such studies or reports. Notwithstanding Section 4.11 above, Purchaser shall
                                             ------------
have no liability or culpability of any nature as a result of having provided
such information to Seller or as a result of Seller's reliance thereon or
arising out of the fact that Purchaser merely conducted such tests or studies,
so long as Purchaser's actions do not aggravate any pre-existing liability of
Seller. In the event that such reports, tests or studies indicate the existence
or reasonable potential existence of any contamination of any portion of the
Property that is not disclosed in the Property Documents and that is material
(meaning that the reasonably estimated cost of remediation and/or other
liability associated therewith, as determined by Seller's environmental
consultants, exceeds $50,000.00), then Seller may terminate this Agreement by
giving written notice to Purchaser within ten (10) business days after Purchaser
has provided Seller with copies of such reports, tests or studies, whereupon the
Earnest Money shall be returned to Purchaser, the parties shall have no further
obligations hereunder except for obligations that expressly survive the
termination hereof, and Seller shall pay to Purchaser an amount equal to the
lesser of (A) Purchaser's actual out-of-pocket expenditures incurred directly in
connection with negotiating this Agreement and/or conducting due diligence
activities contemplated hereunder, or (B) Twenty-Five Thousand and No/100
Dollars ($25,000.00), provided, however, that Purchaser must make written demand
of Seller for such reimbursement and provide Seller reasonable

supporting documentation of actual expenditures within thirty (30) days of the
termination of this Agreement, and if Purchaser fails to provide such written
demand and supporting documentation within such thirty (30) day period, then
Purchaser shall be deemed to have forever waived its right to recover any amount
from Seller.

shall review title to the Property as disclosed by the Title Commitment and the
Survey. Seller shall have no obligation to cure title objections except
financing liens of an ascertainable amount created by, under or through Seller,
which liens Seller shall cause to be released at or prior to Closing (with
Seller having the right to apply the Purchase Price or a portion thereof for
such purpose), and Seller shall deliver the Property free and clear of any such
financing liens. Seller further agrees to remove any exceptions or encumbrances
to title which are voluntarily created by, under or through Seller after the
Effective Date without Purchaser's consent (if requested, such consent shall not
be unreasonably withheld or delayed). The term "Permitted Exceptions" shall
                                                --------------------
mean: the specific exceptions (excluding exceptions that are part of the

                    ARTICLE 6 - Operations and Risk of Loss
                    ---------------------------------------

     6.1  Ongoing Operations.  From the Effective Date through Closing:

          6.1.1  Leases and Service Contracts. Seller will perform its material
obligations under the Leases and Service Contracts.

          6.1.2  New Contracts. Except as provided in Subsection 6.1.4, Seller
                                                      ----------------
will not enter into any contract that will be an obligation affecting the
Property subsequent to the Closing, except contracts entered into in the
ordinary course of business that are terminable without cause and without the
payment of any termination penalty on not more than thirty (30) days' prior
notice.

          6.1.3  Maintenance of Improvements; Removal of Personal Property.
Subject to Sections 6.2 and 6.3, Seller shall maintain all Improvements
           --------------------
substantially in their present condition (ordinary wear and tear and casualty
excepted) and in a manner consistent with Seller's maintenance of the
Improvements during Seller's period of ownership. Seller will not remove any
Tangible Personal Property except as may be required for necessary repair or
replacement, and replacement shall be of approximately equal quality and
quantity as the removed item of Tangible Personal Property.

          6.1.4  Leasing. Seller will not amend or terminate any existing Lease
or enter into any new Lease without providing Purchaser (i) all relevant
supporting documentation, as reasonably determined by Seller, including, without
limitation, tenant financial information to the extent in Seller's possession,
and (ii) as to any such amendment or termination of a Lease or new Lease which
is to be executed after the expiration of the Inspection Period, Seller's
request for Purchaser's approval. If Purchaser's consent is requested by Seller
as to any amendment or termination of a Lease or new Lease, Purchaser agrees to
give Seller written notice of approval or disapproval of a proposed amendment or
termination of a Lease or new Lease within three (3) business days after
Purchaser's receipt of the items in (i) and (ii) of this Subsection 6.1.4. If
                                                         ----------------
Purchaser does not respond to Seller's request within such time period, then
Purchaser will be deemed to have approved such amendment, termination or new
Lease. Purchaser's approval rights and obligations will vary depending on
whether the request for approval from Seller is delivered to Purchaser before or
after the expiration of the Inspection Period, as follows:

                 (a)  With respect to a request for approval delivered by Seller
     to Purchaser before the expiration of the Inspection Period, Purchaser's
     consent shall not be required. Moreover, whether or not Purchaser consents
     to an amendment or termination of a Lease or the entering into of a new
     Lease, Seller may amend or terminate a Lease or enter into a new Lease at
     anytime prior to the expiration of the Inspection Period; however, if
     Purchaser does not consent to same or is not deemed to have approved same,
     and if Seller elects to amend or terminate a Lease or enter into a new
     Lease notwithstanding Purchaser's failure to approve same, then Purchaser
     may, at the time Seller notifies Purchaser of the execution of said
     amendment, termination or new Lease, elect to terminate this Agreement and
     receive a return of the Earnest Money; provided that if Purchaser does not
     elect to terminate within five (5) days after said notification from
     Seller, then Purchaser shall have waived its right to terminate pursuant to
     this Subsection 6.1.4.
          ----------------

                 (b)  With respect to a request for approval delivered by Seller
     to Purchaser after the expiration of the Inspection Period, Purchaser may
     withhold its consent at its sole discretion, and Seller may not amend or
     terminate a Lease or enter into a new Lease without Purchaser's written
     consent.

     6.2  Damage. If prior to Closing the Property is damaged by fire or other
casualty, Seller shall estimate the cost to repair and the time required to
complete repairs and will provide Purchaser written notice of Seller's
estimation (the "Casualty Notice") as soon as reasonably possible after the
                 ---------------
occurrence of the casualty.

          6.2.1  Material. In the event of any Material Damage to or destruction
of the Property or any portion thereof prior to Closing, either Seller or
Purchaser may, at its option, terminate this Agreement by delivering written
notice to the other on or before the expiration of thirty (30) days after the
date Seller delivers the Casualty Notice to Purchaser (and if necessary, the
Closing Date shall be extended to give the parties the full thirty-day period to
make such election and to obtain insurance settlement agreements with Seller's
insurers). Upon any such termination, the Earnest Money shall be returned to
Purchaser and the parties hereto shall have no further rights or obligations
hereunder, other than those that by their terms survive the termination of this
Agreement. If neither Seller nor Purchaser so terminates this Agreement within
said thirty (30) day period, then the parties shall proceed under this Agreement
and close on schedule (subject to extension of Closing as provided above), and
as of Closing Seller shall assign to Purchaser, without representation or
warranty by or recourse against Seller, all of Seller's rights in and to any
resulting insurance proceeds (including any rent loss insurance applicable to
any period on and after the Closing Date) due Seller as a result of such damage
or destruction and Purchaser shall assume full responsibility for all needed
repairs, and Purchaser shall receive a credit at Closing for any deductible
amount under such insurance policies (but the amount of the deductible plus
insurance proceeds shall not exceed the lesser of (A) the cost of repair or (B)
the Purchase Price and a pro rata share of the rental or business loss proceeds,
if any). For the purposes of this Agreement, "Material Damage" and "Materially
                                              ---------------       ----------
Damaged" means damage which, in Seller's reasonable estimation, exceeds
-------
$100,000.00 to repair or which, in Seller's reasonable estimation, will take
longer than ninety (90) days to repair.

          6.2.2  Not Material. If the Property is not Materially Damaged, then
neither Purchaser nor Seller shall have the right to terminate this Agreement,
and Seller shall, at its option, either (i) repair the damage before the Closing
in a manner reasonably satisfactory to Purchaser, or (ii) credit Purchaser at
Closing for the reasonable cost to complete the repair (in which case Seller
shall retain all insurance proceeds and Purchaser shall assume full
responsibility for all needed repairs).

     6.3  Condemnation. If proceedings in eminent domain are instituted with
respect to the Property or any portion thereof, Purchaser may, at its option, by
written notice to Seller given within ten (10) days after Seller notifies
Purchaser of such proceedings (and if necessary the Closing Date shall be
automatically extended to give Purchaser the full ten-day period to make such
election), either: (i) terminate this Agreement, in which case the Earnest Money
shall be immediately returned to Purchaser and the parties hereto shall have no
further rights or obligations, other than those that by their terms survive the
termination of this Agreement, or (ii) proceed under this Agreement, in which
event Seller shall, at the Closing, assign to Purchaser its entire right, title
and interest in and to any condemnation award, and Purchaser shall have the sole
right after the Closing to negotiate and otherwise deal with the condemning
authority in respect of such matter. If Purchaser does not give Seller written
notice of its election within the time required above, then Purchaser shall be
deemed to have elected option (ii) above.

                              ARTICLE 7 - Closing
                              -------------------

     limitation, the Tenant Receivables described in Subsection 8.1.3(b) below
                                                     -------------------
     (collectively, "Unbilled Tenant Receivables"), which amount shall be
                     ---------------------------
     delivered to Seller; and (iv) thereafter, to delinquent Tenant Receivables
     which were due and payable as of Closing but not collected by Seller as of
     Closing (collectively, "Uncollected Delinquent Tenant Receivables"), which
                             -----------------------------------------
     amount shall be delivered to Seller. Notwithstanding the foregoing, Seller
     shall have the right to pursue the collection of Uncollected Delinquent
     Tenant Receivables for a period of one (1) year after Closing without

     tenant's Lease) against such tenant other than to sue for collection. Any
     sums received by Purchaser to which Seller is entitled shall be held in
     trust for Seller on account of such past due rents payable to Seller, and
     Purchaser shall remit to Seller any such sums received by Purchaser to

     Closing Date, Seller shall remit to Purchaser that portion of the monies so
     received by Seller to which Purchaser is entitled within ten (10) business
     days after receipt thereof. With respect to Unbilled Tenant Receivables,
     Purchaser covenants and agrees to (A) bill the same when billable and (B)
     cooperate with Seller to determine the correct amount of operating expenses
     and/or taxes due. The provisions of this Subsection 8.1.3(a) shall survive
                                              -------------------
     the Closing.

                 (b)  Without limiting the generality of the requirements of
     Subsection 8.1.3(a)(ii) above, if the final reconciliation or determination
     -----------------------
     of operating expenses and/or taxes due under the Leases shows that a net
     amount is owed by Seller to Purchaser, said amount shall be paid by Seller
     to Purchaser within ten (10) business days of such final determination
     under the Leases. If the final determination of operating expenses and/or
     taxes due under the Leases shows that a net amount is owed by Purchaser to
     Seller, Purchaser shall, within ten (10) business days of such final
     determination, remit said amount to Seller. Purchaser agrees to receive and
     hold any monies received on account of such past due expenses and/or taxes
     in trust for Seller and to pay same promptly to Seller as aforesaid. The
     provisions of this Subsection 8.1.3(b) shall survive the Closing.

Closing all leasing commissions under the Leasing Commission Agreements, costs
for tenant improvements, legal fees and other costs and expenses (collectively,
"Leasing Costs") that are due prior to Closing with respect to Leases in force
 -------------
as of or prior to the Effective Date; provided, however, that Seller shall have
no obligation to pay, and Purchaser shall assume the obligation to pay, all
leasing commissions payable with respect to any option to renew or option to
expand that has not been exercised prior to the Effective Date, which obligation
shall survive the Closing. As of Closing, Purchaser shall assume Seller's
obligations for Leasing Costs incurred with respect to Leases and Lease renewals
and extensions executed subsequent to the Effective Date.

     8.3  Closing Costs. Closing costs shall be allocated between Seller and
Purchaser in accordance with Section 1.2.
                             -----------

     8.4  Final Adjustment After Closing. If final bills are not available or
cannot be issued prior to Closing for any item being prorated under Section 8.1,
                                                                    -----------
then Purchaser and Seller agree to allocate such items on a fair and equitable
basis as soon as such bills are available, final adjustment to be made as soon
as reasonably possible after the Closing. Payments in connection with the final
adjustment shall be due within thirty (30) days of written notice. All such

     8.5  Tenant Deposits. All tenant security deposits collected and not
applied by Seller (and interest thereon if required by law or contract) shall be

to the extent they are credited or transferred to Purchaser.

     8.6  Commissions. Seller shall be responsible to Broker for a real estate
sales commission at Closing (but only in the event of a Closing in strict
accordance with this Agreement) in accordance with a separate agreement between
Seller and Broker. Broker may share its commission with any other licensed
broker involved in this transaction, but the payment of the commission by Seller
to Broker shall fully satisfy any obligations of Seller to pay a commission
hereunder. Under no circumstances shall Seller owe a commission or other
compensation directly to any other broker, agent or person. Any cooperating
broker shall not be an affiliate, subsidiary or related in any way to Purchaser.
Other than as stated above in this Section 8.6, Seller and Purchaser each
                                   -----------
represent and warrant to the other that no real estate brokerage commission is
payable to any person or entity in connection with the transaction contemplated
hereby, and each agrees to and does hereby indemnify and hold the other harmless
against the payment of any commission to any other person or entity claiming by,
through or under Seller or Purchaser, as applicable. This indemnification shall
extend to any and all claims, liabilities, costs and expenses (including
reasonable attorneys' fees and litigation costs) arising as a result of such
claims and shall survive the Closing.

Agreement and are remade as of the Closing Date and shall not be deemed to be
merged into or waived by the instruments of Closing, but shall survive the
Closing for a period of twelve (12) months (the "Survival Period"). Terms such
                                                 ---------------
as "to Seller's knowledge," "to the best of Seller's knowledge" or like phrases
mean the actual present and conscious awareness or knowledge of Stephen Abelman,
asset manager of the Property and David Bell, Senior Project Manager ("Asset
                                                                       -----
Manager's Employees"), without any duty of inquiry or investigation; provided
-------------------
that so qualifying Seller's knowledge shall in no event give rise to any
personal liability on the part of Asset Manager's Employees or any other officer
or employee of Seller or its Asset Manager, on account of any breach of any
representation or warranty made by Seller herein. Said terms do not include
constructive knowledge, imputed knowledge, or knowledge Seller or such persons
do not have but could have obtained through further investigation or inquiry. No
broker, agent, or party other than Seller is authorized to make any
representation or warranty for or on behalf of Seller. Each party shall have the
right to bring an action against the other on the breach of a representation or
warranty hereunder, but only on the following conditions: (i) the party bringing
the action for breach first learns of the breach after Closing and files such
action within the Survival Period, and (ii) neither party shall have the right
to bring a cause of action for a breach of a representation or warranty unless
the damage to such party on account of such breach (individually or when
combined with damages from other breaches) equals or exceeds $10,000. Neither
party shall have any liability after Closing for the breach of a representation
or warranty hereunder of which the other party hereto had knowledge as of
Closing. Furthermore, Purchaser agrees that the maximum liability of Seller for
the alleged breach of any or all representations or warranties set forth in this
Agreement is limited to $500,000. The provisions of this Section 9.3 shall
                                                         -----------
survive the Closing. Any breach of a representation or warranty that occurs
prior to Closing shall be governed by Article 10.

                       ARTICLE 10 - Default and Remedies
                       ---------------------------------

        10.1   Seller's Remedies. If Purchaser fails to perform its obligations
pursuant to this Agreement at or prior to Closing for any reason except failure
by Seller to perform hereunder, or if prior to Closing any one or more of
Purchaser's representations or warranties are breached in any material respect
and remain


Agreement of Purchase and Sale - (1111 Durham Ave., S. Plainfield, NJ) - Page 19
----------------------------------------------------------------------
<PAGE>

uncured, Seller shall be entitled, as its sole remedy (except as provided in
Sections 4.11, 8.6, 10.3 and 10.4 hereof), to terminate this Agreement and
---------------------------------
recover the Earnest Money as liquidated damages and not as penalty, in full
satisfaction of claims against Purchaser hereunder. Seller and Purchaser agree
that Seller's damages resulting from Purchaser's default are difficult, if not
impossible, to determine and the Earnest Money is a fair estimate of those
damages which has been agreed to in an effort to cause the amount of such
damages to be certain. Notwithstanding anything in this Section 10.1 or in
                                                        ------------
Exhibit G to the contrary, in the event of Purchaser's default or a termination
---------
of this Agreement, Seller shall have all remedies available at law or in equity
in the event Purchaser or any party related to or affiliated with Purchaser is
asserting any claims or right to the Property that would otherwise delay or
prevent Seller from having clear, indefeasible and marketable title to the
Property, and in said event Seller shall not be required to submit such matter
to arbitration as contemplated by Exhibit G. In all other events Seller's
                                  ---------
remedies shall be limited to those described in this Section 10.1 and Sections
                                                     ------------     --------
4.11, 8.6, 10.3 and 10.4 hereof. If Closing is consummated, Seller shall have
------------------------
all remedies available at law or in equity in the event Purchaser fails to
perform any obligation of Purchaser under this Agreement.

        10.2   Purchaser's Remedies. If Seller fails to perform its obligations
pursuant to this Agreement for any reason except failure by Purchaser to perform
hereunder, or if prior to Closing any one or more of Seller's representations or
warranties are breached in any material respect, Purchaser shall elect, as its
sole remedy, either to (i) terminate this Agreement by giving Seller timely
written notice of such election prior to or at Closing and recover the Earnest
Money, (ii) enforce specific performance, or (iii) waive said failure or breach
and proceed to Closing. Notwithstanding anything herein to the contrary,
Purchaser shall be deemed to have elected to terminate this Agreement if
Purchaser fails to deliver to Seller written notice of its intent to file a
claim or assert a cause of action for specific performance against Seller on or
before ten (10) business days following the scheduled Closing Date or, having
given such notice, fails to file a lawsuit asserting such claim or cause of
action in the county in which the Property is located within two (2) months
following the scheduled Closing Date. Purchaser's remedies shall be limited to
those described in this Section 10.2 and Sections 10.3 and 10.4 hereof. If,
                        ------------     ----------------------
however, the equitable remedy of specific performance is not available,
Purchaser may seek any other right or remedy available at law or in equity;
provided, however, that in no event shall Seller's liability exceed the lesser
of (i) $50,000.00 or (ii) the actual reasonable out-of-pocket expenses incurred
by Purchaser and paid (A) to Purchaser's attorneys in connection with the
negotiation of this Agreement and (B) to unrelated and unaffiliated third party
consultants in connection with the performance of examinations, inspections
and/or investigations pursuant to Article 4. For purposes of this provision,
                                  ---------
specific performance shall be considered not available to Purchaser only if a
court of competent jurisdiction (or an arbitrator, as per Exhibit G) determines
                                                          ---------
conclusively that Purchaser is entitled to specific performance on the merits of
its claim but said court or arbitrator is unable to enforce specific performance
due to reasons beyond the control of the court or arbitrator. IN NO EVENT SHALL
SELLER'S DIRECT OR INDIRECT PARTNERS, SHAREHOLDERS, OWNERS OR AFFILIATES, ANY
OFFICER, DIRECTOR, EMPLOYEE OR AGENT OF THE FOREGOING, OR ANY AFFILIATE OR
CONTROLLING PERSON THEREOF HAVE ANY LIABILITY FOR ANY CLAIM, CAUSE OF ACTION OR
OTHER LIABILITY ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE PROPERTY,
WHETHER BASED ON CONTRACT, COMMON LAW, STATUTE, EQUITY OR OTHERWISE.

        10.3   Attorneys' Fees. In the event either party hereto employs an
attorney in connection with claims by one party against the other arising from
the operation of this Agreement, the non-prevailing party shall pay the
prevailing party all reasonable fees and expenses, including attorneys' fees,
incurred in connection with such transaction.

        10.4   Other Expenses. If this Agreement is terminated due to the
default of a party, then the defaulting party shall pay any fees or charges due
to Escrow Agent for holding the Earnest Money as well

as any escrow cancellation fees or charges and any fees or charges due to the
Title Company for preparation and/or cancellation of the Title Commitment.

Agreement prior to the expiration of the Inspection Period, Purchaser

such investigations of the Property as Purchaser deemed necessary to satisfy
itself as to the condition of the Property and the existence or non-existence or
curative action to be taken with respect to any Hazardous Materials on or
discharged from the Property, and will rely solely upon same and not upon any
information provided by or on behalf of Seller or its agents or employees with

party at Closing, each party agrees to perform, execute and deliver, but without
any obligation to incur any additional liability or expense, on or after the
Closing any further deliveries and assurances as may be reasonably necessary to
consummate the transactions contemplated hereby or to further perfect the
conveyance, transfer and assignment of the Property to Purchaser.

        12.15  Discharge of Obligations. The acceptance of the Deed by Purchaser
shall be deemed to be a full performance and discharge of every representation
and warranty made by Seller herein and every agreement and obligation on the
part of Seller to be performed pursuant to the provisions of this Agreement,
except those which are herein specifically stated to survive Closing.

        12.16  ERISA. Under no circumstances shall Purchaser have the right to
assign this Agreement to any person or entity owned or controlled by an employee
benefit plan if Seller's sale of the Property to such person or entity would, in
the reasonable opinion of Seller's ERISA advisors or consultants, create or
otherwise cause a "prohibited transaction" under ERISA. In the event Purchaser
assigns this Agreement or transfers any ownership interest in Purchaser, and
such assignment or transfer would make the consummation of the transaction
hereunder a "prohibited transaction" under ERISA and necessitate the termination
of this Agreement then, notwithstanding any contrary provision which may be
contained herein, Seller shall have the right to terminate this Agreement.

        12.17  No Third Party Beneficiary. The provisions of this Agreement and
of the documents to be executed and delivered at Closing are and will be for the
benefit of Seller, Asset Manager and Purchaser only and are not for the benefit

(other than Asset Manager) shall have the right to enforce the provisions of
this Agreement or of the documents to be executed and delivered at Closing,
except that a tenant of the Property may enforce Purchaser's indemnity
obligation under Section 4.11 hereof.

                             ---------------------


The parties have agreed to submit certain disputes to mandatory arbitration in
accordance with the following provisions:

        Scope of Arbitration. The parties to this Agreement have agreed to
        --------------------
submit all disputes to final and binding arbitration as the sole and exclusive
remedy for all claims for damages arising out of, involving, or relating to (a)
this Agreement or (b) the events giving rise to this Agreement, including all
non-contractual claims for damages related to this Agreement or the events
giving rise to it (including claims for fraudulent inducement of contract).
Notwithstanding the foregoing, the dispute resolution procedure set forth below
shall not apply to (i) claims for injunctive or other equitable relief, or (ii)
any claims for specific performance. The parties agree that two (2) sets of
rules will apply, depending on the amount in controversy. If the amount in
controversy is equal to or less than $50,000.00, then SET A (as set forth below)
will apply. If the amount in controversy is greater than $50,000.00, then SET B
will apply. The amount in controversy is calculated using the amount of actual
damages alleged by the Claiming Party (defined below), exclusive of interest and
attorneys' fees. The dispute resolution procedure set forth below does not
independently give rise to any right or remedy. The procedure is intended to be
applied to rights or remedies expressly granted in other sections of this
Agreement.

        Notice of Dispute. Any party shall give the other parties written notice
        -----------------
of the existence and nature of any dispute proposed to be arbitrated (the
"Written Notice"). The Written Notice must be served on the other parties as
 --------------
required below. The party serving Written Notice shall be referred to as the
"Claiming Party." The party to whom the claims are directed shall be referred to
 --------------
as the "Responding Party."
        ----------------

        Appointment of Arbitrators.
        --------------------------

               SET A: The parties agree that these disputes will be arbitrated
by a single arbitrator who is a board certified or licensed real estate attorney
in the state in which the Property is located. The parties shall attempt to
agree upon an arbitrator within ten (10) days of the service of the Written
Notice. If the parties are unable to agree, then the arbitrator shall be
appointed from, and pursuant to the rules for commercial arbitration of, the
American Arbitration Association. Prior to appointment, the arbitrator shall
agree to conduct such arbitration in strict accordance with the terms of this
Agreement.

               SET B: The parties agree that these disputes will be arbitrated
by a panel of three (3) arbitrators. Each party shall appoint one person to
serve as an arbitrator within fifteen (15) days of receipt of the Written
Notice. The two (2) arbitrators thus appointed shall within seven (7) days of
their appointment together select a third arbitrator with such knowledge and
expertise as necessary to serve as chairman of the panel of arbitrators
(preferably a board certified or licensed real estate attorney in the state in
which the Property is located), and this person shall serve as chairman. The
three arbitrators shall determine all matters, including the panel's final
decision with respect to the claims presented in the arbitration, by majority
vote. If the two arbitrators selected by the parties are unable to agree upon
the appointment of the third arbitrator within seven (7) days of their
appointment, both shall give written notice of such failure to agree to the
parties, and if the parties fail to agree upon the selection of such third
arbitrator within five (5) days thereafter, such third arbitrator shall be
appointed from, and pursuant to the rules for commercial arbitration of, the
American Arbitration Association. Prior to appointment, each arbitrator shall
agree to conduct such arbitration in strict accordance with the terms of this
Agreement.

<PAGE>

        Initial Meeting of the Arbitrators. Within seven (7) days after the
        ----------------------------------
selection of the last arbitrator (SET A: the arbitrator; SET B: the third
arbitrator), the arbitrator(s) shall conduct an initial meeting with the parties
(the "Initial Meeting"). All meetings between the arbitrators, or between the
      ---------------
arbitrator(s) and the parties, including the Initial Meeting, may be conducted
by telephone, with the exception of the arbitration hearing at which evidence is
presented. At the Initial Meeting, the parties and the arbitrator(s) shall agree
upon a schedule for the arbitration proceedings, with dates no later than the
deadlines provided below. The statement of claim, the response to the statement
of claim and counterclaims (if any), and the response to the counterclaims (if
any) (collectively, the "Pleadings") shall be submitted to each arbitrator on
                         ---------
the date they are served, unless service occurs prior to appointment of all
arbitrators. If service of any of the Pleadings occurs prior to the appointment
of any of the arbitrators, copies of any such Pleadings shall be submitted to
such arbitrator promptly after such arbitrator's appointment.

        Conduct of the Arbitration.
        --------------------------

               SET A: With respect to each dispute to be arbitrated, no more
than six (6) months shall pass between the selection of the arbitrator and the
release of a decision by the arbitrator; no more than two (2) depositions
(lasting in total for both depositions no more than 15 hours) may be taken by
each of the Claiming Party or the Responding Party, and no more than ten (10)
interrogatories may be asked for by each of the Claiming Party or the Responding
Party. The arbitration hearing shall last no more than two (2) days with the
time divided equally between the parties. All proceedings, including discovery,
depositions, and the arbitration hearings shall be governed by the Federal Rules
of Civil Procedure and the Local Rules of Civil Procedure of the United States
District Court for the district in which the Property is located, unless such
rules conflict with the provisions of this Agreement, in which case the
provisions of this Agreement control; provided, however, that the parties agree
that the provisions of Federal Rule of Civil Procedure 26(a) shall not apply.

               SET B: With respect to each dispute to be arbitrated, no more
than eleven (11) months shall pass between the selection of the third arbitrator
and the release of a decision by the arbitration panel; no more than eight (8)
depositions (lasting in total for all eight depositions no more than 50 hours)
may be taken by each of the Claiming Party or the Responding Party, and no more
