Item 2. Acquisition or Disposition of Assets.

                  On July 19, 1996, the Trust acquired a seven-story, 122,000
square foot office building in Cherry Hill, New Jersey (the "LibertyView
Building") from UM Real Estate Investment Company, LLC ("UM") for a cash price
of $10.6 million, of which $9.6 million was paid at the closing. The balance is
payable to UM, in installments, as outlined below:

                  Due Date                  Amount
                  --------                  ------

                  July 31, 1997             $100,000
                  August 31, 1997           $100,000
                  September 31, 1997        $100,000
                  October 31, 1997          $100,000
                  November 31, 1997         $100,000
                  December 31, 1997         $500,000

  The amount of the purchase price was determined through arm's-length
negotiation between the Trust and UM.

                  The LibertyView Building was completed in 1990 and, as of May
30, 1996, the occupancy level was approximately 66%. A single tenant, HIP Health
Plan of NJ, an HMO provider, occupies 37,515 square feet under a lease expiring
January 2007. No other tenant occupies more than 10% of the building. Rentals of
another tenant, Shapiro and Kreisman, a law firm, comprise approximately 15.4%
of the total current base rents for the property. Other tenants in the
LibertyView Building include a regional bank, big six accounting firm and
several Philadelphia-based law firms.

                  The Trust financed its acquisition of the LibertyView Building
through a combination of term financing ($9,777,140), from a commercial bank
(Summit Bank, formerly known as United Jersey Bank), and proceeds from a recent
investment in the Trust by an affiliate of Richard M. Osborne, one of the
Trustees of the Trust. The acquisition portion of the bank loan ($8,480,000)
bears interest at a fixed rate of 8% per annum and matures on January 1, 1999.
The bank loan provides for additional funding of an amount not to exceed $1.3
million, which will be advanced for tenant finishing and leasing commissions on
currently vacant space. The additional funding will be repayable at prime plus
1% and will mature on January 1, 1999.

                  The bank loan will be secured by a first mortgage on the
LibertyView Building, and will generally be non-recourse to the Trust, except
that the Trust will be required to guarantee completion of the tenant
improvements for any new leases, and up to $3 million of principal of the bank
loan plus the amount of principal and interest unpaid as of the date of
acceleration of the bank loan in the event of a default thereunder. The bank has
reserved the right to approve of any material change in the ownership of


                                      -2-
<PAGE>

the Trust, including a change resulting from the contemplated transaction (the
"SSI/TNC Transaction") among the Trust, Safeguard Scientifics, Inc. and The
Nichols Company, and in the event the Bank does not approve of any such
ownership change, the loan, at the bank's option, will become repayable without
penalty upon 120 days notice. If the bank were to withhold approval of the
SSI/TNC Transaction and require repayment of its loan, the Trust would be
required to seek replacement financing and there can be no assurance that the
Trust could obtain such replacement financing or that any such replacement
financing would be on terms acceptable to the Trust. If the Trust were unable to
refinance the loan, the LibertyView Building could be transferred to the bank
with a consequent loss of income and asset value to the Trust.

                  The following table sets forth scheduled lease expirations for
leases in place at the LibertyView Building as of June, 1996 for each of the
years beginning with January 1, 1996, assuming no tenant exercises renewal
options or is terminated due to default:

                  REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To Brandywine Realty Trust:

We have audited the statement of revenue and certain expenses of the LibertyView
Building described in Note 1 for the year ended December 31, 1995. This
financial statement is the responsibility of the LibertyView Building's
management. Our responsibility is to express an opinion on this financial
statement based on our audit.

We conducted our audit in accordance with generally accepted auditing standards.
Those standards require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and the significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.

The accompanying statement of revenue and certain expenses was prepared for the
purpose of complying with the rules and regulations of the Securities and
Exchange Commission and is not intended to be a complete presentation of the
LibertyView Building's revenue and expenses.

In our opinion, the financial statement referred to above presents fairly, in
all material respects, the revenue and certain expenses of the LibertyView
Building for the year ended December 31, 1995, in conformity with generally
accepted accounting principles.

                                                             ARTHUR ANDERSEN LLP

                              LIBERTYVIEW BUILDING

               NOTES TO STATEMENTS OF REVENUE AND CERTAIN EXPENSES

                                DECEMBER 31, 1995

1. BASIS OF PRESENTATION:

The statements of revenue and certain expenses reflect the operations of the
LibertyView Office Building (the "LibertyView Building") located in New Jersey,
which will be acquired by Brandywine Realty Trust (the "Trust") from an
unaffiliated party by July 19, 1996. The LibertyView Building has an aggregate
net leasable area of approximately 121,700 square feet and is 63% leased as of
December 31, 1995.

The books of the LibertyView Building are maintained on a modified cash basis.
Adjusting entries have been made to present the accompanying financial
statements in accordance with generally accepted accounting principles. The
accompanying financial statements exclude certain expenses--such as interest,
depreciation and amortization, professional fees, and other costs not directly
related to the future operations of the LibertyView Building that may not be
comparable to the expenses expected to be incurred by the Trust.

2. OPERATING LEASES:

Base rents presented for the year ended December 31, 1995 and the three month
period ended March 31, 1996, include straight-line adjustments for rental
revenue increases in accordance with generally accepted accounting principles.
The aggregate rental revenue increase resulting from the straight-line
adjustments for the year ended December 31, 1995, and the three month period
ended March 31, 1996, was $127,000 and $12,000, respectively.

Tenants whose minimum rental payments equaled 10% or more of the total base
rents in 1995 were:

           HIP Health Plan of NJ                  $462,000
           Shapiro and Kreisman                   $185,000

In September 1995, LibertyView Building entered into a 60-month lease agreement
with Sleepcare, a related party to the seller, of which $18,000 and $14,000 of
base rents for the 




                                      -7-
<PAGE>

year ended December 31, 1995 and the three-month period ended March 31, 1996,
respectively, is included in the statements of revenue and certain expenses.

The LibertyView Building is leased to tenants under operating leases with
expiration dates extending to the year 2007. Future minimum rentals under
noncancelable operating leases, excluding tenant reimbursements of operating
expenses as of December 31, 1995, are as follows:

                 1996                                $1,205,000
                 1997                                 1,177,000
                 1998                                 1,118,000
                 1999                                 1,118,000
                 2000                                   950,000
                 Thereafter                           4,440,000

Certain leases also include provisions requiring tenants to reimburse management
costs and other overhead up to stipulated amounts.

             PRO FORMA CONDENSED CONSOLIDATING FINANCIAL INFORMATION

                                   (Unaudited)

                  The following sets forth the pro forma condensed consolidating
balance sheet of Brandywine Realty Trust as of March 31, 1996 and the pro forma
condensed consolidating statements of operations for the year ended December 31,
1995, and the three-month period ended March 31, 1996.

                  The pro forma condensed consolidating financial information is
presented as if the consummated transactions of (a) the June 21, 1996 investment
by the Turkey Vulture Fund XIII, Ltd. (the "RMO Fund") of $1,330,000 in debt and
equity securities of the Trust; and (b) the July 19, 1996 acquisition of the
LibertyView Office Building (the "LibertyView Building") by the Trust had been
consummated on March 31, 1996, for balance sheet purposes and January 1, 1995

         5.3 If at the time of Closing, the Property or any part thereof shall
be or shall have been affected by a confirmed assessment or assessments (that
is, any assessment the first installment of which has been paid), then for the
purposes of this Agreement all the unpaid installments of any such assessment,
including those which are to become due and payable after the Closing, shall be
deemed to be due and payable and to be liens upon the Property and shall be paid

         5.7 If any of the foregoing cannot be apportioned at Closing because of

and prorations under this Article 5 shall be made as of 11:59 p.m. on the day
prior to the Closing Date; that is, all income and expenses for the Closing Date
shall be for the account of Buyer.

         5.9 The provisions of this Article 5 shall survive Closing.

                                    Article 6

                                      TITLE

         6.1 Conveyance to Buyer of title to the Property shall be by delivery
of Seller's bargain and sale deed with covenants against the grantor's acts
("Seller's Deed"), in recordable form, conveying good, insurable and marketable
fee simple title to the Property subject only to the Permitted Exceptions and
real estate taxes not due and payable at the date of Closing.

         6.2 Conveyance to Buyer of title to (i) the Personal Property shall be
by delivery of Seller's bill of sale with covenants and general warranties of
good and marketable title (but without warranties of quality, merchantability,
or fitness for purpose or use) free and clear of all security interests, liens,
charges, claims and encumbrances, and (ii) the remainder of the Assets shall be
by delivery of Seller's unconditional deeds, assignments and other conveyance
instruments as set forth herein with covenants and general warranties of good
and marketable title, free and clear of all security interests, liens, charges,
claims and encumbrances.

         6.3 This Agreement and the Closing hereunder is conditioned upon
Buyer's being entitled to obtain upon payment of the appropriate premium, an
ALTA-B Owner's Policy of Title Insurance in the full amount of the Purchase
Price by any reputable title insurance company licensed to do business in the
State of New Jersey, at regular rates, which policy shall insure that the fee
simple title to the Property is vested in Buyer free and clear of all liens and
encumbrances other than the exceptions set forth on Exhibit "C" as well as all
other matters revealed by the Title Commitment (as hereinafter defined) and not
objected to by Buyer during the Due Diligence Period (the "Permitted
Exceptions"). During the Due Diligence Period, Buyer shall obtain, and deliver a
copy thereof to Seller, a commitment (the "Title Commitment") for the issuance
at Closing, upon payment of the premium therefor, of Buyer's Title Policy for
the Property.

         6.4 As soon as practicable after the date hereof, Buyer, at Buyer's
expense, may order a current as-built survey ("Survey") by a licensed surveyor,
acceptable to Buyer and Title Company, of the Property which shall describe the
Property, be dated after the date hereof, and contain a surveyor's certificate
in favor of Buyer, the Title Company and such other parties as Buyer shall
designate in form and substance satisfactory for, among other things, deletion
of the standard survey exception from the title insurance policy and consistent
with and as required by the next succeeding sentences.

         6.5 Buyer shall request Title Company and such licensed surveyor to
deliver to Seller copies of the Commitment and Survey at such times as same are
delivered to Buyer. If the matters revealed by the Commitment and the Survey,
other than the following matters:

             a.   real estate taxes not yet due and payable at the date of the
Commitment;

             b.   liens, charges, claims and encumbrances of a definite or
ascertainable monetary amount, all of which shall be paid off or removed of
record by Seller, at Seller's expense, and released at Closing, and Seller
agrees so to do and effect same;

             c.   matters which the Commitment states will be removed upon
presentation of Seller's ALTA Statement and other documentation, which ALTA
Statement and other documentation shall be presented by Seller at Closing, and
Seller agrees so to do, and which matters shall be so removed from the title
insurance policy at Closing;

             d.   public utility easements which do not underlie the 
Improvements and do not otherwise interfere with the ownership, use or operation
of the Property; and

                                       -6-
<PAGE>
             e.   Permitted Exceptions

are not satisfactory to Buyer, such matters not so satisfactory to Buyer
hereinafter called "Unsatisfactory Matters", then, at the election of Buyer, at
Buyer's sole discretion, Buyer, unless Seller (with Buyer's approval, which
approval may be withheld by Buyer at its sole and unreviewable discretion)
causes Title Company to delete such Unsatisfactory Matters from the Commitment
or commit to insure over such Unsatisfactory Matters in a manner satisfactory to
Buyer, at any time on or prior to the Closing Date (by notice to Seller which
may be orally given) may terminate this Agreement, in which event the Deposit
and Buyer's reasonable out-of-pocket expenses not to exceed Twenty Thousand
Dollars ($20,000), shall be returned to Buyer and neither party shall have any
further rights, obligations or liabilities hereunder. If Buyer does not so elect
to terminate, Buyer may attempt to cure such Unsatisfactory Matters, such cost
to be borne by Seller in an amount not to exceed Twenty Thousand Dollars
($20,000), the remaining Unsatisfactory Matters set forth in the Survey and
Commitment shall become part of the Commitment and the state of title shown in
the Commitment shall be deemed acceptable to Buyer and Seller shall have no
further obligation in respect of such remaining Unsatisfactory Matters. Such
Unsatisfactory Matters shall thereupon become so-called "Permitted Exceptions"
and may be set forth as permitted encumbrances in Seller's Deed.

         6.6 Buyer's obligation to close hereunder shall be conditioned upon
Seller's being able, at Closing, to deliver to Buyer title to the Property,
fee-simple, free and clear of all liens, claims and encumbrances other than the
Permitted Exceptions; and, if Seller is not able to so deliver title or correct
or cure the Unsatisfactory Matters, Buyer may either accept such title as Seller
can deliver, pursue any remedy or modification of any noted title or survey
defect, the cost thereof to be reimbursed by Seller in an amount not to exceed
Twenty Thousand Dollars ($20,000) or terminate this Agreement in which event the
Deposit and Buyer's out-of-pocket expenses not to exceed Twenty Thousand Dollars
($20,000) and, thereafter, shall be forthwith returned to Buyer and thereafter
neither party shall have any further rights or obligations hereunder, except for
those which by their terms survive termination hereof. However, if the Property
shall be subject to any liens or encumbrances in a fixed or ascertainable
amount, Seller shall pay same at or prior to Closing, and may use the proceeds
of Closing for such purpose, and if Seller does not satisfy same at or prior to
Closing, Buyer shall have the right in addition to all other remedies provided
for herein and at law or in equity, to satisfy same at Closing and deduct the
cost thereof from the Purchase Price to be paid at Closing.

         6.7 In connection with the owner's title insurance policy which Buyer
intends to obtain in connection with this transaction, if the Title Commitment
is obtained and delivered to Seller prior to the end of the Due Diligence
Period, along with specific requests and forms of documents therefor reasonably
satisfactory to Seller's counsel, Seller undertakes and agrees to provide such
information to, and execute such certificates and affidavits as comport with the
actual state of facts in existence as of the Closing Date, for the benefit of
and as are reasonably and customarily required by, the issuing title insurance
company, in order that Buyer may have any exclusions or exceptions to coverage
removed (other than the Permitted Exceptions) including, without limitation,
those pertaining to creditors' rights and fraudulent conveyances.

         6.8 Seller agrees to execute and deliver and to do or cause to be
executed and delivered and to be done any documents and agreements and any
things which may be necessary to or desired by Title Company to furnish the
required title insurance.

                                    Article 7

         8.1 As a material inducement to Buyer to enter into this Agreement and
to proceed to its consummation on the Closing Date, Seller makes the following 
representations, warranties, and agreements, to the best of its knowledge, such
knowledge being that of Arthur W. Hicks, Jr. and Terry Cassidy, as follows, all
upon which Buyer relies:

             (a)  Subject to the Permitted Exceptions and the rights of
tenants under Tenant Leases, Seller is the fee simple owner of and is lawfully
seized and possessed of the Assets, there are no outstanding agreements of sale
or options with respect to the Property, and no party or entity has any rights
to possess or occupy the Assets. Seller does not own any property contiguous to
the Assets.

             (b)  To the best of Seller's knowledge, neither the execution nor 
delivery of this Agreement, nor the consummation of the transactions described 
herein or contemplated hereby nor compliance with the terms hereof by Seller 
will conflict with or result in the breach of any terms of, or constitute a 
default under any agreement or instrument of any kind to which Seller is a
party or by which Seller is bound.

             (c)  Seller has received no notice of any currently pending
Condemnation (as hereinafter defined) affecting the Property, or of any

assessments against the Assets.

             (e)  Seller has not received service of process or similar formal 
notice with respect to any actions, litigation, suits, proceedings, appeals 
(including, without limitation, tax or assessment appeals) or claims affecting 
the Assets which, if determined adversely to Seller or the Assets, would have a
material adverse effect on the operation of the business of the Assets as 
currently conducted or render title to the Assets unmarketable.

             (f)  Seller has made no application, submission or request for
any site plan approval, subdivision approval, variance, waiver, license, sewer
permit, building permit or any other approval from any governmental authority,
for development and/or use of the Property, which is now pending.

relating to the Tenant Leases. Seller has not entered into any other agreements
for brokerage commissions relating to the property. As a condition precedent to

unable to obtain the non-Key Tenant Estoppel Letters, with respect to any of the
Tenant Leases, such failure shall not be deemed a default hereunder. Title shall
be transferred at Closing subject to and together with the benefit of the Tenant
Leases. The copies of the Tenant Leases furnished to Buyer are true, correct and
complete copies thereof and such Tenant Leases have not been modified or amended
except pursuant to the amendments delivered to Buyer; such Tenant Leases are in
full force and effect; no rent or additional rent has been paid thereunder in
advance of the due date; to the best knowledge of Seller, there is no default by
landlord or tenant in the keeping, observance or performance of any material
covenant, agreement, term, provision or condition contained therein; to the best
knowledge of Seller, none of the tenants have any rights to offsets, deductions
or defenses of the payment of any rent or additional rent except as may be set
forth in the Tenant Leases; and there are no option to purchase, right of first
offer, right of first refusal or other provision granting to the tenants the
right to acquire the Property or any portion thereof or any right to terminate
any of the Tenant Leases in the event of a sale of the Property except as may be
set forth in the Tenant Leases; Seller has received and holds no security
deposit in respect of the Tenant Leases other than as disclosed in Exhibit "D".

             (i)  The Property is currently subject to the management, leasing,
service or maintenance contracts and other commitments described on Exhibit "E"
attached hereto (the "Service Contracts"); provided however, that Buyer shall 
only be obligated to assume those Service Contracts which are cancelable on not
more than thirty (30) days notice pursuant to their terms. There are no 
agreements with respect to the operation or maintenance of the Property which 
would be binding upon Buyer after Closing other than the Service Contracts and 
certain of the Permitted Exceptions. Title shall be transferred at Closing 
subject to and together with the benefit of the Service Contracts.

         8.2 All of the covenants, agreements, representations and warranties of
Seller contained in this Agreement shall be deemed remade on and as of Closing,

with no broker or other person (including The Rubin Organization) entitled to
claim fees for finders or brokerage services in connection with the negotiation,

and expenses (including reasonable attorneys' fees) relating to such claims or
arising therefrom or incurred by the indemnified party in connection with the
enforcement of this indemnification provision. The provisions of this Article
shall survive the Closing or any termination hereof.

                                   Article 10

                                  RISK OF LOSS

         10.1 Fire and Casualty. The risk of loss or damage to the Property by
fire or other casualty not caused by Buyer or by any of Buyer's agents,
employees, contractors and consultants (a "Seller's Cause") until the Closing is
assumed by Seller. If the Property is damaged by a Seller's Cause to the extent
that the cost to repair the Property will exceed $50,000 (a "Terminable Loss")
and the Property is not repaired by Seller prior to the Closing Date, Buyer may
at Buyer's sole option, (a) proceed to Closing without an abatement in Purchase
Price (except for any deductibles as hereinafter provided) and Seller shall
assign all of its insurance claims, including without limitation, casualty and
rent interruption insurance (except for Seller's portion of the rent
interruption insurance up to the Closing Date) and Seller will give Buyer a
credit against the Purchase Price for any deductibles; or (b) terminate this
Agreement by notice to Seller, in which event, the Deposit shall be immediately
returned to Buyer and thereafter neither party shall have any further rights or

                                      -13-
<PAGE>

obligations hereunder, except for those which by their terms survive termination
hereof. If the Property is damaged by a Seller's Cause to the extent that the
cost to repair the Property will not exceed $50,000 and the Property is not
repaired by Seller prior to the Closing Date, the parties shall proceed to
Closing and Seller shall pay Buyer in cash the estimated cost to repair such
damage (or Seller shall adjust the Note appropriately). The extent of damage due
to a Seller's Cause not to be repaired by Seller prior to the Closing Date,
shall be determined as promptly as practicable after occurrence of such damage,
by the estimate of an independent, reputable contractor, licensed and operating
in the general area in which the Property is located, engaged by Seller but
reasonably acceptable to Buyer for the purpose of providing such estimate.

         10.2 Condemnation. In the event that at any time prior to the Closing,
any proceedings shall be commenced or consummated for the taking of all or any
part of the Property, which would materially adversely affect the value of the
Property or the continued conduct of business thereon as currently being
conducted, for public or quasi-public use pursuant to the power of eminent
domain, condemnation or otherwise (a "Condemnation"), Seller shall forthwith
give written notice thereof to Buyer. Buyer may, at its option, within seven (7)
days of receipt by it of notice of such Condemnation, but in any event not later
than one (1) business day prior to the Closing Date (unless such notice of
Condemnation is given later than two (2) business days prior to the Closing
Date, in which event, Buyer shall make its election prior to Closing) elect by
sending notice thereof to Seller either of the following: (a) to terminate this
Agreement, in which event the Deposit shall be immediately returned to Buyer and
thereafter neither party shall have any further rights or obligations hereunder,
except for those which by their terms survive termination hereof; or (b) to
proceed with this Agreement without an abatement in the Purchase Price, in which
case Seller shall assign any and all awards and other compensation to which
Seller is entitled for such Condemnation to Buyer.

                                   Article 11

notices, consents, approvals, submissions or demands shall be hereinafter
collectively called "Notices") given under this Agreement or by applicable law,
rule or regulation by Seller to Buyer or by Buyer to Seller shall be in writing

next following a non-business day of receipt), however delivered or transmitted

         12.1 If Seller defaults in the performance of any of its obligations
under this Agreement, Buyer may, as Buyer's sole remedy, at Buyer's election
either (i) seek to specifically enforce this Agreement against Seller in which
event Buyer shall be entitled to collect from Seller reasonable attorney's fees,
and the costs, of litigation, or (ii) cure such breach, the cost thereof to be
borne by Seller in an amount not to exceed Twenty Thousand Dollars ($20,000), or
(iii) terminate this Agreement by notifying Seller thereof, in which event the
Deposit and Buyer's reasonably documented out-of-pocket costs not to exceed
Twenty Thousand Dollars ($20,000) shall be returned to Buyer and thereafter
neither party shall have any further rights or obligations hereunder, except for
those which by their terms survive termination hereof.

         12.2 If Buyer defaults in the performance of any of its obligations
under this Agreement, Seller may, as Seller's sole remedy, terminate this
Agreement by notifying Buyer thereof, in which event the Deposit shall be
immediately delivered to and retained by Seller as agreed and liquidated damages
hereunder, the parties acknowledging that Seller's damages arising in the event
of such default are difficult, if not impossible to ascertain, and in such
event, thereafter neither party shall have any further rights or obligations
hereunder, except for those which by their terms survive termination hereof.

                                   Article 13

                                SELLER COVENANTS

              (b)  Seller shall not make any new Tenant Leases ("New Tenant
Leases") or any amendments (including extensions and renewals) of or cancel any
existing Tenant Leases without Buyer's prior written consent; provided, however,
Seller shall cooperate with Buyer in presenting new proposals to potential
tenants at rates and terms acceptable to Buyer and Seller shall accompany Buyer,
after prior written notice, on such proposal meetings.

              (c)  Seller shall promptly deliver to Buyer copies of, and shall 
comply with all notices of violations of laws, ordinances, orders, regulations

adverse change (or threat thereof) which shall come to the attention of or 
become known by Seller in the condition (financial or otherwise), operations or
business of Seller or the Assets, and (ii) (without regard to materiality) any 
notice to Seller of any violation or alleged violation of any obligation or 
agreement;

                   6.  without Buyer's prior written consent, not sell, encumber
or grant any interest in the Assets or any part thereof in any form or manner
whatsoever and not perform or permit any act or thing which might diminish or
otherwise adversely affect Buyer's interest under this Agreement or in or to the
Assets or any part thereof or which might prevent Seller's full performance of
its obligations under this Agreement.

              (e)  After the date hereof and until the Closing Date, Seller
will use its best and diligent efforts to keep Buyer timely and fully informed
of any developments which might cause any of the foregoing representations and
warranties to be no longer accurate.

              (f)  Subject to Seller's obligation to keep, repair, replace
and maintain the Assets and to the other provisions hereof, Seller shall deliver
possession of the Assets to Buyer at Closing in the same condition at the
Closing as on the date hereof, excepting therefrom only ordinary interim wear
and tear thereto after the date of the last required repair or replacement.

              (g)  Not to encumber or lien or wilfully permit to be
encumbered with any encumbrance, lien or other claim of right which may affect
title thereto, the Assets, or other rights, appurtenances and herediments to be

day period or any extension thereof, in which case the Deposit shall be returned

                                 INDEMNIFICATION

         Each party hereto hereby agrees to indemnify, hold harmless and defend
the other party, and such party's agents, employees, successors and assigns,
from and against any and all claims, demands, damages, losses, expenses,
liabilities and costs whatsoever, known or unknown, past, present or future
(including, without limitation, court costs and attorneys' fees), arising out
of, or resulting from or attributable to (a) any negligent or wrongful acts or
omissions of the indemnifying party or its agents, employees, contractors or
suppliers with respect to the Assets and (b) any breach or incorrectness of any
representation or warranty made by the indemnifying party in this Agreement,

Seller hereby agrees to indemnify, hold harmless and defend Buyer, Buyer's
employees, successors and assigns, from and against any and all claims, demands,
damages, losses, expenses, liabilities and costs incurred by said indemnified
party by reason of said indemnified party's necessity to defend any suit, action
or proceeding (administrative, judicial or otherwise) brought by a third-party

solely by reason of its being the contract purchaser hereunder (e.g.
condemnation actions, adjacent land owner actions, etc.). This Article shall

         Buyer hereby acknowledges that except with respect to the specific
representations made by Seller under this Agreement, Buyer is purchasing the
Property in "as is" condition based solely upon the investigations undertaken by
Buyer and not upon the representations of any other person. Buyer shall be
solely responsible for the physical condition of the Property, including,
without limitation, the environmental condition of the Property, and shall not
make any claim against Seller related to the physical condition of the Property,
including the environmental condition of the Property (including, without
limitation, any condition above, on or below the ground), Buyer hereby
acknowledging that it has undertaken such investigations as it deems necessary
to make its own determination with respect thereto.

         18.7  Assignment. This Agreement may be assigned, transferred, or

         18.8  Successors. This Agreement shall be binding upon and inure to the

event, however, shall Seller mention Brandywine Realty Trust in any press
release or similar disclosure without obtaining the prior written consent of
Brandywine Realty Trust.

         18.12 Further Assurances. Seller and Buyer each agree to execute and 
deliver all other instruments and take all other action as the other party may 
reasonably request from time to time, after Closing, in order to effectuate the

                                      Exhibit 99.2  First Amendment to Purchase
                                                    and Sale Agreement
                                                    between UM and the Trust
            
                 FIRST AMENDMENT TO PURCHASE AND SALE AGREEMENT

         This First Amendment made this 30th day of May, 1996, by and between UM
REAL ESTATE INVESTMENT COMPANY, LLC ("Seller") and BRANDYWINE REALTY TRUST
("Buyer").

                                   Background

         Seller and Buyer are parties to that certain Purchase and Sale
Agreement made as of the 28th day of March, 1996 (the "Agreement") with respect
to the sale of property known as Block 176.01, Lots 1, 2 and 3 on the official
tax map of the Township of Cherry Hill together with all improvements thereon
(the "Property").

         Buyer has requested that Seller extend the Closing Date and, to the
extent provided herein, the Due Diligence Period, and Seller has agreed to do so
pursuant to the terms and conditions hereafter set forth.

         NOW, THEREFORE, Buyer and Seller, for and in consideration of the
mutual covenants contained herein and other good and valuable consideration, the
receipt of which is hereby acknowledged, intending to be legally bound, do
hereby agree that notwithstanding anything to the contrary contained in the
Agreement:

         1. Definitions. All defined terms herein shall have the meaning
ascribed to them under the Agreement unless specifically provided herein to the
contrary.

         2. Deposit. (a) Article 2.1(a) is amended by adding thereto the
         following:

         In the event Closing does not occur by June 14, 1996, unless due to a
         default by Seller or due to Buyer's termination of the Agreement as
         permitted under Article 3 of this First Amendment, the Title Company
         shall continue to hold the Ninety Thousand Dollars ($90,000) held as
         Deposit, such sum to become non-refundable on June 14, 1996 and Buyer
         shall concurrently pay to the Title Company by June 14, 1996 by
         certified check, bank check or wire transfer, an additional One Hundred
         Fifty Thousand Dollars ($150,000) which shall become part of the
         Deposit and thereupon, the Deposit shall be non-refundable. Buyer's
         failure to pay such additional $150,000 by the above time period to
         Seller shall constitute a default under the Agreement. Until 5 p.m. on
         June 14, 1996, only $10,000 of the Deposit pursuant to subparagraph (b)
         below shall be non-refundable; thereafter, unless Seller defaults
         hereunder, the remaining Two Hundred Forty Thousand Dollars ($240,000)
         shall become non-refundable.

           (b) Ten Thousand Dollars ($10,000) of the Deposit currently held by
         the Title Company shall be deemed non-refundable as of this date and
         shall be immediately paid by the Title Company to Seller. Seller shall
         be entitled to

                                       -1-

         retain such amount in the event Closing does not occur for any reason
         (including Buyer's termination of the Agreement as permitted under the
         Agreement or this First Amendment) unless Seller defaults under the
         Agreement, in which event Seller shall reimburse such $10,000 to Buyer.
         In the event Buyer terminates the Agreement as permitted under Article
         3 of this First Amendment, the remaining Ninety Thousand Dollars
         ($90,000) of the Deposit shall be returned by the Title Company to
         Buyer if such date is on or before June 14, 1996; however, if Seller
         defaults prior to Closing, the entire Deposit, including the additional
         $150,000 and interest shall be returned to Buyer.

         3. Due Diligence. Article 3 of the Agreement is amended by adding
thereto the following:

         Buyer acknowledges that it has completed all of the investigations
         which it is entitled to undertake pursuant to Article 3 of the
         Agreement with the exception of those specific items set forth on
         Schedule 1 attached hereto and made a part hereof (the "Remaining Due
         Diligence Items"). Buyer shall, from and after the date hereof, no
         longer have the right to terminate the Agreement for any reason other
         than (i) Buyer's good faith determination not to proceed based on the
         results of one or more of the Remaining Due Diligence Items or (ii)
         Buyer's good faith determination that it is unable to obtain
         satisfactory financing to acquire the Property. The $50,000 addition to
         the Deposit required under Article 2.1(a) of the Agreement must be paid
         by Buyer to the Title Company by 5 p.m. E.D.S.T. on May 30, 1996
         notwithstanding the failure of Buyer to have completed the Remaining
         Due Diligence Items. Such additional $50,000 shall be governed by the
         terms of amended Article 2.1. Buyer shall have the right to terminate
         this Agreement solely as a result of Buyer's good faith determination
         that is not satisfied with the result of one or more of the Remaining
         Due Diligence Items or Buyer's good faith determination that it is
         unable to obtain satisfactory financing to acquire the Property, by
         notice to Seller not later than 5 p.m. on June 14, 1996 following which
         (provided Buyer is not then in default hereunder), the Title Company
         shall return the remaining $90,000 of the Deposit to Buyer and
         thereafter neither party shall have any further rights or obligations
         under the Agreement, except for those which by their terms survive
         termination of the Agreement. If Buyer does not terminate the Agreement
         as permitted under this Article 3 of this First Amendment, the entire
         Deposit (e.g., $250,000) shall become non-refundable so long as Seller
         does not default hereunder.

         4. Closing. Article 4 of the Agreement shall be amended to provide that
Closing shall be held on or before July 19, 1996, at the time and place set
forth in the Agreement.

                                       -2-

         5. Signatures. This First Amendment may be executed in one or more
counterparts, each of which shall be deemed an original and part of one and the
same document. Telefax signatures shall be deemed the equivalent of original
signatures.

         Except to the extent specifically set forth herein, the terms and
conditions of the Agreement are hereby ratified and confirmed. In the event of
any conflict between the terms of the Agreement and the terms of this First
Amendment, the terms of this First Amendment shall prevail.

                  3. Due Diligence. Article 3 is amended by adding thereto the
following:

                  Notwithstanding the terms as stated in the Agreement, Buyer
                  acknowledges that it has completed all of its investigations
                  which it is entitled to undertake pursuant to Article 3 of the
                  Agreement with the exception of that specific item set forth
                  on Schedule 1 attached hereto and made a part hereof (the
                  "Remaining Due Diligence Item"). Buyer and Seller further
                  acknowledge and agree that (a) Buyer has made a good faith
                  effort to obtain financing to acquire the Property from United
                  Jersey Bank, Seller's current lender (the "Bank"), (b) Bank
                  has advised Buyer orally that such UJB Letters have been
                  approved by its Credit Committee, and (c) Seller will derive a
                  benefit from Buyer's utilization of the Bank. Buyer shall,
                  from and after the date hereof, no longer have the right to
                  terminate the Agreement for any reason other than (i) Buyer's
                  good faith determination not to proceed based on the results
                  of the Remaining Due Diligence Item or (ii) Bank's inability
                  to deliver a formal UJB commitment letter (the "UJB
                  Commitment") to Buyer on or before June 24, 1996 through no
                  fault or affirmative action of Buyer. Buyer shall have the
                  right to terminate the Agreement solely as a result of Buyer's
                  good faith determination that it is not satisfied with the
                  result of the Remaining Due Diligence Item on or before June
                  28, 1996 or if Bank does not deliver the UJB Commitment on or
                  before June 24, 1996. If Buyer terminates this Agreement for
                  either of events (i) or (ii) herein and Seller is not in
                  default hereunder, the Title Company shall disburse the
                  Deposit as follows: (A) Two Hundred Forty Thousand Dollars
                  ($240,000) to Buyer and (B) Ten Thousand Dollars ($10,000) to
                  Seller; provided, however, if Seller is in default hereunder,
                  the aforesaid Ten Thousand Dollars ($10,000) shall be returned
                  to Buyer; and, provided, further, thereafter, neither party
                  shall have any further rights or

                                       -2-

                  permitted under this Article 3 of this Second Amendment, the
                  entire Deposit (e.g., $250,000) shall be non-refundable.

                           acknowledge and agree that if Buyer affirmatively or
                           intentionally causes the Bank to fail to fund the
                           loan at Closing, such funding shall not be a

and conditions of the Agreement are hereby ratified and confirmed. In the event
of any conflict between the terms of the Agreement and the terms of this Second
Amendment, the terms of this Second Amendment shall prevail.

                                                                   July 19, 1996

         FOR VALUE RECEIVED, BRANDYWINE REALTY TRUST, a Maryland real estate
investment trust, whose address is Two Greentree Center, Suite 100, Marlton, New
Jersey 08053 ("Maker"), hereby promises to pay to the order of UM REAL ESTATE
INVESTMENT COMPANY, LLC, a New Jersey limited liability company, with offices at
56 Haddon Avenue, Haddonfield, New Jersey 08033 ("Payee"), the principal sum of
ONE MILLION DOLLARS ($1,000,000) (the "Loan"), together with interest on the
outstanding balance thereof at the per annum rate hereafter set forth.

         1. Principal and interest, if any, shall be payable at the aforesaid
office of Payee, or such other place as the holder of this Note may designate,
in the following manner:

            (a) Except as otherwise provided for in the Event of Default, the
Note will not bear interest during the term hereof.

            (b) Maker shall make six (6) payments of principal as follows,
unless Payee shall demand immediate payment in accordance with the terms of this
Note:

                  July 31, 1997                      $100,000
                  August 31, 1997                    $100,000

                  October 31, 1997                   $100,000
                  November 30, 1997                  $100,000
                  December 31, 1997                  $500,000

            (c) The entire unpaid principal together with accrued but unpaid
interest thereon and all other sums due under this Note are due on December 31,
1997 (the "Maturity Date") which date is of the essence. THIS NOTE IS PAYABLE IN
FULL AT THE MATURITY DATE. PAYEE IS UNDER NO OBLIGATION TO REFINANCE THE LOAN OR
EXTEND THE TIME FOR PAYMENT AT THAT TIME.

         2. The obligation secured hereby may be prepaid in full or in part, at
any time, without penalty.

         3. All payments, including any prepayment, shall be in lawful money of
the United States of America in immediately available funds and shall be applied
first to unpaid, earned fees, then to delinquent escrows, then to accrued
interest, and lastly, to principal outstanding.

         4. This Note is secured by (1) a subordinated (second) Mortgage and
Security Agreement of even date herewith (the "Mortgage"), covering certain land
and premises located at the corner of Haddonfield Road and Chapel Avenue, Cherry
Hill Township, Camden County, New Jersey, as more particularly described in the
Mortgage (together, the "Mortgaged Property"), (2) a second priority security
interest in certain personal property located upon the Mortgaged Property and
other collateral described in UCC-1 Financing Statements; and (3) a subordinated
collateral assignment of rents and leases arising out of the Mortgaged Property.
Any failure by Maker to comply with the terms, covenants or conditions of the
foregoing documents or any other document executed by Maker in connection with
the Loan (collectively, the "Loan Documents") shall, upon the elapsing of any
applicable notice and/or grace period, without cure, automatically constitute an
Event of Default under this Note, and all of the provisions contained in the
Loan Documents by Maker to Payee to secure the indebtedness set forth herein are
hereby incorporated by this reference thereto as if the same were set forth
herein in detail.

         5. The occurrence of one or more of the following, after the expiration
of all applicable notice and cure periods, if any, (an "Event of Default"), at
the option of Payee, shall constitute a default by Maker under this Note:

            (a) If Maker shall fail to make any payment when it is due (provided
that Payee agrees not more than once during any twelve (12) month period during
the term of this Note to give Maker notice of such failure, and allow Maker five
(5) days after the giving of such notice to cure such failure, prior to same
being an Event of Default);

            (b) If any certification, warranty, or representation made or
hereafter made by Maker to Payee should prove to be false, incorrect, incomplete
or misleading; and/or

            (c) An Event of Default shall occur under the Mortgage and/or any of
the other Loan Documents.

            Upon the occurrence of an Event of Default, subject to a certain
Subordination Agreement of even date herewith between Payee and Summit Bank,
Payee may, at its option, declare the entire unpaid

                                        1


<PAGE>



principal balance of this Note together with interest accrued thereon and all
other sums due or owed by Maker hereunder, or under any of the other Loan
Documents, to be due and payable immediately, together with reasonable fees for
legal counsel and for collection, all of which sums shall bear interest
(effective upon such Event of Default) at the rate which is four (4.0%) percent
above the domestic "Prime Rate" as published in the Wall Street Journal from
time to time under the heading "Money Rates", and payment of the same may be
enforced and recovered by the entry of judgment of this Note and the issuance of
execution thereon.

            If any payment due hereunder shall be delinquent for more than ten
(10) days after such payment is due and payable, Maker shall pay to Payee a late
charge equal to five percent (5%) of such installment. The right to require a
late charge is in addition to and not by way of limitation of any other rights
and remedies which Payee may have.

         6. The remedies of Payee provided herein and in the Mortgage and all of
the other Loan Documents shall be cumulative and concurrent, and may be pursued
singly, successively and together at the sole discretion of Payee, and may be
exercised as often as occasion therefor shall occur; and the failure to exercise
any such right or remedy shall in no event be construed as a waiver or release
of the same.

         7. Maker (and all endorsers, sureties and guarantors) waives
presentment for payment, demand, notice of demand, notice of nonpayment or
dishonor, protest and notice of protest of this Note. Liability hereunder shall
be unconditional and shall not be affected in any manner by any indulgence,
extension of time, renewal, waiver or modification granted or consented to by
Payee, unless same is in writing and signed by an authorized officer of Payee.

         8. It is the intention of the Maker and Payee to conform strictly to
the usury laws from time to time in force, and all agreements between Maker and
Payee, whether now existing or hereafter arising and whether oral or written,
are hereby expressly limited so that in no contingency or event whatsoever,
whether by acceleration of maturity hereof or otherwise, shall the amount paid
or agreed to be paid to Payee or the holder hereof, or collected by Payee or
such holder, for the use, forbearance or detention of the money to be loaned
hereunder or otherwise, or for the payment or performance of any covenant or
obligation contained herein or in the Mortgage and Security Agreement or any of
the other Loan Documents, or in any other document evidencing, securing or
pertaining to the indebtedness evidenced hereby, exceed the maximum amount
permissible under applicable usury laws. If under any circumstances whatsoever
fulfillment of any provision hereof or of the Mortgage or any of the other Loan
Documents, at the time performance of such provision shall be due, shall involve
transcending the limit of validity prescribed by law, then ipso facto, the
obligation to be fulfilled shall be reduced to the limit of such validity; and
if under any circumstances Payee or any other holder hereof shall ever receive
an amount deemed interest, by applicable law, which would exceed the highest
lawful rate, such amount that would be excessive interest under applicable usury
laws shall be applied to the reduction of the principal amount owing hereunder
or to other indebtedness secured by the Mortgage and not to the payment of
interest, or if such excessive interest exceeds the unpaid balance of principal
and other indebtedness, the excess shall be deemed to have been a payment made
by mistake and shall be refunded to Maker or to any other person making such
payment on Maker's behalf. All sums paid or agreed to be paid to the holder
hereof for the use, forbearance or detention of the indebtedness of Maker
evidenced hereby, outstanding from time to time shall, to the extent permitted
by applicable law, be amortized, pro-rated, allocated and spread from the date
of disbursement of the proceeds of this Note until payment in full of such
indebtedness so that the actual rate of interest on account of such indebtedness
is uniform through the term hereof. The terms and provisions of this paragraph
shall control and supersede every other provision of all agreements between
Payee and Maker and any endorser or guarantor of this Note.

         10. Except as hereinafter set forth, Maker shall not have any personal
liability for the payment or performance of any obligations hereunder and in the
event of a default hereof, Payee will look solely to the Mortgaged Property and
the rents, issues and profits thereof and any other collateral specifically
pledged, assigned or granted by Maker as security herefor, and any judgment
obtained against Maker shall so note by its terms or as otherwise permissible by
law. Notwithstanding the foregoing, in the event of a default under this Note,
this obligation shall be recourse to the Maker in an amount which is the
difference between $3,000,000 and that portion of the recourse obligation from
Maker to Summit Bank (pursuant to a Promissory Note in an amount not to exceed
$9,777,240 of even date herewith (the "Summit Note")) which is not credited by
Summit Bank under the Summit Note upon an event of default (as defined under the
Summit Note) by Maker under the Summit Note (e.g., if Summit Bank utilizes
$2,000,000 of the recourse amount as a portion of or as all of its remedy under
the Summit Note, as the case may be, after an event of default under the Summit
Note, this Note to Payee shall be recourse in the amount of $1,000,000). In no
event, however, shall (i) this obligation be recourse to the Maker in an amount
greater than the total amount owing by Maker under this Note, nor (ii) the total
recourse to Maker pursuant to this Note and the Summit Note exceed $3,000,000.

         11. This Note and the performance of Maker's obligations hereunder
shall be governed by the laws of the State of New Jersey.

         12. The words "Payee" and "Maker" whenever occurring herein shall be
deemed and construed to include the respective successors and assigns of Payee
and Maker.

         13. THE PARTIES HEREBY IRREVOCABLY AND UNCONDITIONALLY AGREE THAT ANY
SUIT, ACTION OF OTHER LEGAL PROCEEDING ARISING OUT OR IN CONNECTION WITH THIS
NOTE SHALL BE BROUGHT IN THE COURTS OF RECORD OF THE STATE OF NEW JERSEY OR THE
COURTS OF THE UNITED STATES LOCATED IN THE STATE OF NEW JERSEY. THE PARTIES
CONSENT TO JURISDICTION

                                        2


<PAGE>


OF EACH SUCH COURT IN ANY SUCH SUIT, ACTION OR PROCEEDING, AND WAIVE ANY
OBJECTION TO THE VENUE OF ANY SUCH SUIT, ACTION OR PROCEEDING IN ANY OF SUCH
COURTS.

         14. TO THE EXTENT PERMITTED BY LAW, EACH PARTY HEREBY WAIVES ITS RIGHT
TO TRIAL BY JURY IN ANY LITIGATION BETWEEN PAYEE AND MAKER ARISING OUT OF OR IN
CONNECTION WITH THE LOAN AND ANY OF THE DOCUMENTS EVIDENCING THE LOAN OR
EXECUTED IN CONNECTION THEREWITH BY EITHER PARTY. EACH PARTY ACKNOWLEDGES THE
IMPORTANCE OF THIS RIGHT AND MAKES A KNOWING WAIVER THEREOF IN CONSIDERATION OF
THE WILLINGNESS OF MAKER TO MAKE THE LOAN TO PAYEE.

         IN WITNESS WHEREOF, Maker has duly executed this Note the day and year
first above mentioned.

and Summit Bank of even date herewith (the "Subordination Agreement"), hereby
grant, convey, assign and mortgage unto Mortgagee all of its interest in and
agrees that Mortgagee shall have a security interest in, all that, certain

including the cash and non-cash proceeds thereof;

         (3) All building materials, fixtures, building machinery and building

         (4) Any and all tenements, hereditaments and appurtenances belonging to
the Land or any part thereof or intended so to be in any way appertaining

other property and interests are sometimes collectively referred to herein as
the "Mortgaged Property"); and

         (6) All of Mortgagor's right, title and interest now or hereafter

payable therefrom.

         TO HAVE AND TO HOLD on a subordinated (second) basis the Mortgaged
Property hereby conveyed or mentioned and intended so to be, unto Mortgagee, to
its own use forever.

         PROVIDED ALWAYS, and this instrument is upon the express condition
that, if Mortgagor pays to Mortgagee the principal sum mentioned in the Note,
the interest thereon and all other sums payable by Mortgagor to Mortgagee as are
secured hereby, in accordance with the provisions of the Note and this

                                        1


<PAGE>
Mortgage, at the times and in the manner specified, without deduction, fraud or
delay, and Mortgagor performs and complies with all the agreements, conditions,
covenants, provisions and stipulations contained herein and in the Note and all
of the other documents executed by Mortgagor in connection therewith (together,
the "Loan Documents"), then this Mortgage and the estate hereby granted shall
cease and become void and Mortgagee shall release the same, at the cost and
expense of Mortgagor.

         THIS MORTGAGE is a second purchase-money mortgage, subject and
subordinate solely to that certain first mortgage (the "First Mortgage") dated
of even date herewith, in the principal amount of $9,777,140 and given by
Mortgagor in favor of Summit Bank.

         MORTGAGOR COVENANTS, subject to the First Mortgage and that certain
Subordination Agreement, among Mortgagor, Mortgagee and Summit Bank dated this
date (the "Subordination Agreement") that until the indebtedness secured hereby
is fully repaid:

         1. Seizin and Warranty: Mortgagor warrants that it is indefeasibly
seized of the Mortgaged Property in fee simple, free and clear of all liens and
encumbrances other than those appearing on the marked-up Commitment to Insure
Title issued by Surety Title Corporation under Application No. ST 20505 at the
time of initial closing on the Loan. Mortgagor further warrants that Mortgagor
has full power and lawful right to convey the same in fee simple as aforesaid;
that it shall be lawful for Mortgagee at all times peaceably and quietly to
enter upon, hold, occupy and enjoy the Mortgaged Property and every part
thereof; that all property, fixtures and equipment described herein will be
fully paid for and free from all liens, encumbrances, title retaining contracts
and security interests when delivered and/or installed upon the Mortgaged
Property; that such property, fixture and equipment shall, to the extent
permitted by law, be deemed to be realty and a part of the freehold.

         2. Payment and Performance: Mortgagor shall pay to Mortgagee, in
accordance with the terms of the Note and this Mortgage, the principal and
interest, and other sums therein set forth; and shall perform and comply with
all the agreements, conditions, covenants and stipulations of the Note, this
Mortgage and all of the other Loan Documents, the terms of all of which are
incorporated herein by reference.

         3. Maintenance of Mortgaged Property: Mortgagor shall abstain from and
shall not permit the commission of waste in or about the Mortgaged Property;
shall not remove or demolish, or alter the structural character of, any building
erected at any time on the Mortgaged Property, without the prior written consent
of Mortgagee; shall not permit the Mortgaged Property to become vacant, deserted
or unguarded; and shall maintain the Mortgaged Property in good condition and
repair, reasonable wear and tear excepted and will make or cause to be made, as
and when necessary, all repairs, renewals, replacements, structural and
non-structural, exterior and interior, ordinary and extraordinary, foreseen and
unforseen.

         4. Insurance and Condemnation: Mortgagor shall keep the Mortgaged
Property continuously insured against loss or damage by fire, and against such
other hazards as Summit Bank and Mortgagee may reasonably require under an
insurance policy with "broad form" endorsement, issued by Aetna Casualty &
Surety Company, on a non-contributing and non-reporting form basis, for the full
replacement value thereof and including a business interruption policy for a
period of not less than one (1) year. Subject to the First Mortgage, all
policies, including policies for any amounts carried in excess of the required
minimum and policies not specifically required by Mortgagee, shall be maintained
in full force and effect, shall be delivered to Mortgagee, with premiums
prepaid, shall be endorsed with a standard mortgagee clause in favor of
Mortgagee, with Mortgagee and Summit Bank named as loss payee, shall provide for
at least thirty (30) days prior written notice of cancellation, non-renewal or
material amendment to Mortgagee, shall be written by insurance companies having
an A.M. Best Company, Inc. rating of "A" or higher and a financial size category
of not less than XII, or otherwise as approved by Mortgagee. In addition,
Mortgagor shall at all times be protected by comprehensive general public
liability (in an amount of not less than $1,000,000.00 per occurrence), property
damage, and flood (if applicable) insurance policies, and such other insurance
as is, from time to time, carried by most owners of properties similar to the
Mortgaged Property, including, but not limited to, boiler insurance, business
interruption insurance and employer's liability insurance, naming Mortgagee as
an additional insured and containing a waiver of subrogation against Mortgagee.
Such coverages at all times shall be evidenced by current certificates of

<PAGE>

insurance issued to Mortgagee providing for thirty (30) days prior written
notice of cancellation, non-renewal or material amendment of coverage. If the
insurance, or any part thereof, shall expire, be withdrawn, be materially
amended or become void or unsafe by reason of the failure or impairment of the
capital of any company in which the insurance may then be carried, or if for any
reason whatever the insurance shall be unsatisfactory to Mortgagee, Mortgagor
shall immediately place new insurance on the Mortgaged Property, satisfactory to
Summit Bank. All renewal policies, with premiums paid, shall be delivered to
Mortgagee at least thirty (30) days before expiration of the old policies. In
the event of loss, Mortgagor will give prompt notice thereof to Mortgagee, and
Mortgagee and Summit Bank may make proof of loss if not made promptly by
Mortgagor (but shall have no obligation to do so).

                  Except as may be provided in the First Mortgage, each
insurance company concerned is hereby authorized and directed to make payment
under such insurance, including return of unearned premiums, directly to
Mortgagee instead of to Mortgagor and Mortgagee jointly, and Mortgagor appoints

                                        2


<PAGE>
Mortgagee, irrevocably, as Mortgagor's attorney-in-fact to endorse any draft
therefor. Mortgagee shall apply any casualty insurance proceeds toward the costs
of reconstruction or restoration of the Mortgaged Property as long as Mortgagor
is not in default, and in such case of a default against the outstanding balance
of the Loan, notwithstanding that the amount owing thereon may not then be due
and payable. If Mortgagee becomes the owner of the Mortgaged Property or any
part thereof by foreclosure or otherwise, such policies, including all right,
title and interest of Mortgagor thereunder, shall become the absolute property
of Mortgagee.

                  Except as may be provided in the First Mortgage, Mortgagor
hereby assigns to Mortgagee any and all awards heretofore and hereafter made to
the present and all subsequent owners of the Mortgaged Property by any
governmental or other lawful authorities for taking or damaging by eminent
domain the whole or any part of the Mortgaged Property or any easement therein,
including any awards for any changes of grades of streets, which said awards are
hereby assigned to Mortgagee, who is hereby authorized to collect and receive
the proceeds of any such awards from such authorities and to give proper
receipts and acquittances therefor, and to apply the same (after deduction of
attorney's fees and other costs of collecting the funds) toward the payment of
the amount owing on account of this Mortgage and the Note, notwithstanding that
the amount owing thereon may not then be due and payable. Mortgagor hereby
agrees, upon request, to make, execute and deliver any and all assignments and
other instruments sufficient for the purpose of evidencing and effecting such
assignment of the aforesaid awards to Mortgagee. The aforesaid awards are
assigned to Mortgagee free, clear and discharged of any and all encumbrances of
any kind or nature whatsoever. Mortgagor further agrees to give Mortgagee prompt
notice of the actual or threatened commencement of any proceedings in the nature
of eminent domain affecting all or any part of the Mortgaged Property and to
deliver to Mortgagee copies of any papers served upon Mortgagor in connection
with any such proceedings. No settlement for the damages sustained shall be made
by Mortgagor without Mortgagee's prior written approval, which approval shall
not be unreasonably withheld.

                  If, prior to the receipt by Mortgagee of either such insurance
proceeds or condemnation awards, or both, the Mortgaged Property or any part
thereof shall have been sold on foreclosure of this Mortgage, Mortgagee shall
have the right, whether or not a deficiency judgment on the Note shall have been
sought, recovered or denied, to receive said sums to the extent of the debt
remaining unsatisfied after such sale, with interest thereon at the applicable
rate set forth in the Note, and to receive the reasonable counsel fees, costs
and disbursements incurred by Mortgagee in connection with the collection of
said sums.

                  In the event of foreclosure of this Mortgage or other transfer
of title to the Mortgaged Property in extinguishment of the Loan, all right,
title and interest of Mortgagor in and to any insurance policies then in force
shall pass to the purchaser or grantee, and Mortgagor hereby appoints Mortgagee
as its attorney-in-fact, in Mortgagor's name, to assign and transfer all such
policies and proceeds to such purchaser or grantee.

                  Mortgagor may maintain insurance required by means of one or
more blanket insurance policies maintained by Mortgagor; provided, however, that
(A) any such policy shall specify, or Mortgagor shall furnish to Mortgagee a
written statement from the insurer so specifying, the maximum amount of the
total insurance afforded by such blanket policy that is allocated to the
Mortgaged Property and any sublimits in such blanket policy applicable to the
Mortgaged Property, (B) each such blanket policy shall include an endorsement
providing that, in the event of a loss resulting from an insured peril,
insurance proceeds shall be allocated to the Mortgaged Property in an amount
equal to the coverages required to be maintained by Mortgagor as provided above
and (C) the protection afforded under any such blanket policy shall be no less
than that which would have been afforded under a separate policy or policies
relating only to the Mortgaged Property.
<PAGE>

         5. Taxes and Other Charges: Mortgagor shall pay when due and payable
and before interest or penalties are due thereon, all taxes, assessments, water
and sewer rents and all other charges or claims which may be assessed, levied,
or filed at any time against Mortgagor, the Mortgaged Property or any part
thereof or against the interest of Mortgagee therein, or which by any present or
future law may have priority over the indebtedness secured hereby either in lien
or in distribution out of the proceeds of any judicial sale; and Mortgagor shall
produce to Mortgagee within ten (10) days of Mortgagee's written request the
official receipt for the payment thereof; provided that, if Mortgagor in good
faith and by appropriate legal action shall contest the validity of any such
item, or the amount thereof, and shall have established on its books a reserve
for the payment thereof in such amount as Mortgagee may require, then Mortgagor
shall not be required to pay the item or to produce the required receipts while
the reserve is maintained and so long as the contest operates to prevent
collection, is maintained and prosecuted with diligence, and shall not have been
terminated or discontinued adversely to Mortgagor. Mortgagor covenants that no
owner of the Mortgaged Property shall be entitled to any credit by reason of the
payment of any tax thereon.

         6. Installments for Insurance, Taxes and Other Charges: Subject to the
First Mortgage, without limitation of anything else herein contained, Mortgagor,
after an Event of Default, shall pay to Mortgagee monthly at the time when the
monthly installment of principal and/or interest is payable, an amount equal to
one-twelfth (1/12) of the annual premiums not prepaid for the fire and extended
coverage

                                        3


<PAGE>
insurance and the annual real estate taxes, water and sewer rents, any special
assessments, charges or claims and any other item which at any time may be or
become a lien upon the Mortgaged Property prior to the lien of this Mortgage;
and on demand from time to time, Mortgagor shall pay to Mortgagee any additional
sums necessary to pay such taxes and other items, all as estimated by Mortgagee;
the amounts so paid shall be security for payment of taxes and said other items
shall be used in payment thereof if Mortgagor is not otherwise in default
hereunder. Mortgagor will produce to Mortgagee, not later than ten (10) days
before the date on which any installment for insurance, taxes, and other charges
shall becomes due and owing, receipts for such installments for insurance,
taxes, and other charges. No amount so paid shall be deemed to be trust funds
and may be commingled with general funds of Mortgagee, and no interest shall be
payable thereon. If, pursuant to any provision of this Mortgage, the whole
amount of the unpaid principal debt becomes due and payable, Mortgagee shall
have the right, at its election, to apply any amount so held, in such order and
in such amounts as Mortgagee may elect, against: (a) any amounts payable by
Mortgagor hereunder or under any of the other Loan Documents, and/or (b) accrued
and unpaid interest, and/or (c) the outstanding principal balance of the Loan.
At Mortgagee's option, Mortgagee from time to time may waive, and after any such
waiver may reinstate, the provisions of this Paragraph 6 requiring the monthly
payments. Mortgagor will furnish to Mortgagee bills and other requests for
payment in sufficient time to enable Mortgagee to pay such taxes, assessments,
levies, charges and fees as provided above.

         7. Security Agreement: This Mortgage constitutes a security agreement
under the Uniform Commercial Code as adopted in the State and creates a second
priority security interest in the Mortgaged Property including, without
limitation, all furniture, fixtures, equipment and personal property installed
in, or to be placed upon, or used in connection with, or necessary for, the
operation of the Mortgaged Property, except such personal property owned by
tenants in the Mortgaged Property and such personal property owned by the
contractor or subcontractors performing work on the Mortgaged Property, whether
stored on the Mortgaged Property or elsewhere and used or to be used in
connection with the Mortgaged Property; all leases, rents, issues and profits,
and all inventory, accounts, accounts receivable, contract rights, general
intangibles, chattel paper, instruments, documents, notes, drafts, letters of
credit, insurance policies, insurance and condemnation awards and proceeds,
trade names, trademarks and service marks arising from or related to the
Mortgaged Property and any business conducted thereon by Mortgagor; and all
replacements, additions, accessions and cash and non-cash proceeds and products
thereof. Mortgagor shall execute, deliver, file and refile any financing
statements or other security agreements Mortgagee may require from time to time
to confirm the lien of this Mortgage and the security interest hereby created
with respect to such property, and Mortgagor shall pay any reasonable costs or
fees incurred in connection therewith. Without limiting the foregoing, Mortgagor
hereby irrevocably appoints Mortgagee attorney-in-fact for Mortgagor to execute,
deliver and file such instruments for and on behalf of Mortgagor after notice
and non-delivery for five (5) days. Notwithstanding any release of any or all of
the property included in the Mortgaged Property which is deemed "real property",
any proceedings to foreclose this Mortgage or its satisfaction of record, the
terms hereof shall survive as a security agreement with respect to the security
created hereby and referred to herein until the repayment or satisfaction in
full of the obligations of Mortgagor as are now or hereafter evidenced by the
Note and the other Loan Documents. As to those items of the Mortgaged Property
that are, or are to become, fixtures (together with all products and proceeds
thereof), it is intended that THIS MORTGAGE SHALL BE EFFECTIVE AS A FINANCING
STATEMENT FILED AS A FIXTURE FILING from the date of its filing in the real
estate records of the County where the Mortgaged Property is located. The name
of the record owner of said Mortgaged Property is Mortgagor set forth on page
one of this Mortgage. Information concerning the security interest created by
this Mortgage may be obtained from Mortgagee, as subordinated secured party, at
its address as set forth on page one of this Mortgage. The address of Mortgagor,
as debtor, is as set forth on page one of this Mortgage. This Mortgage covers
goods which are or are to become fixtures.

         8. Existence and Taxes: If Mortgagor or any successor or grantee of
Mortgagor is a corporation or partnership, it shall keep in effect its existence
and rights as a corporation or partnership under the laws of the state of its
incorporation or formation and its right to own property and transact business
in the State during the entire time it has any ownership interest in the
Mortgaged Property. For all periods during which title to the Mortgaged Property
or any part thereof shall be held by a corporation or partnership subject to
corporate taxes, partnership taxes or taxes similar to such taxes, Mortgagor
shall file returns for such taxes with the proper authorities, bureaus or
departments, and it shall pay, when due and payable and before interest or
penalties are due thereon, all taxes owing by Mortgagor to the United States, to
such state of incorporation or formation and to the State and any political
subdivision thereof, and shall produce to Mortgagee, if requested, receipts
showing payment of any and all such taxes, charges or assessments, all
settlements, notices of deficiency or overassessment and any other notices
pertaining to Mortgagor's tax liability, which may be issued by the United
States, such state of incorporation or formation, or the State and any political
subdivision thereof.
<PAGE>

         9. Intentionally Deleted.

        10. Compliance with Law and Regulations: Mortgagor shall comply with
all laws, ordinances, regulations, restrictions, requirements and orders of all
federal, state, municipal and other governmental authorities, of courts and of
insurance companies relating to Mortgagor or affecting the Mortgaged Property or
the use and operation thereof. Mortgagor also shall promptly comply with the
provisions of any recorded covenants, conditions or restrictions to which the
Mortgaged Property or any part thereof may at any time

                                        4


<PAGE>
be subject. Mortgagor shall not cause or allow the construction or erection of
any public, municipal or utility improvements upon the Mortgaged Property other
than those required by public authorities, without the prior written consent of
Mortgagee, which consent shall not be unreasonably withheld. Mortgagor shall not
drill or extract or enter into any lease for the drilling for or extraction of
oil, gas or other hydrocarbon substances or any mineral of any kind or character
on or from the Mortgaged Property or any part thereof without the prior written
consent of Mortgagee.

         11. Inspection: Mortgagee and any persons authorized by Mortgagee shall
have the right at any time, upon reasonable notice to Mortgagor, to enter the
Mortgaged Property at a reasonable hour to inspect and photograph its condition
and state of repair in such a manner so as not to unreasonably intefere with
Mortgagor's operations.

         12. Declaration of No Set-Off: Within fifteen (15) days after requested
to do so by Mortgagee, Mortgagor shall certify to Mortgagee or to any proposed
assignee of this Mortgage, in a writing duly acknowledged, the amount of
principal, interest and other charges then owing on the obligation secured by
this Mortgage and whether there are any set-offs or defenses against it, and if
such set-offs or defenses are asserted, a detailed explanation thereof.

         Within fifteen (15) days after requested to do so by Mortgagor,
Mortgagee shall certify to Mortgagor, in a writing duly acknowledged, the amount
of principal, interest and other charges then owing on the obligation secured by
this Mortgage and whether Mortgagor is in default hereunder or under any of the
documents securing the indebtedness evidenced hereby or whether, to the best
knowledge of Mortgagee, any event has occurred which with the giving of notice
or passage of time, or both, would constitute an Event of Default hereunder.

         13. Right to Remedy Defaults: In the event that Mortgagor should fail
to pay taxes, assessments, water and sewer charges or other lienable claims
(except in case of contest as aforesaid) or insurance premiums, or fail to make
necessary repairs or permit waste, or otherwise fail to comply with its
obligations hereunder or under the Note or any other document executed in
connection with this Mortgage, then Mortgagee, at its election and upon ten (10)
days prior written notice to Mortgagor, shall have the right to make any payment
or expenditure which Mortgagor should have made, or which Mortgagee reasonably
deems advisable to protect the security of this Mortgage or the Mortgaged
Property, without prejudice to any of Mortgagee's rights or remedies available
hereunder or otherwise, at law or in equity. All such sums, as well as costs,
advanced by Mortgagee pursuant to this Mortgage shall be due within three (3)
days of notice and reasonably detailed explanation thereof from Mortgagor to
Mortgagee, shall be secured hereby, and shall bear interest at the default rate,
if any, provided in the Note, and if none is so provided, then at the prevailing
rate of interest stipulated in the Note, from the date of payment by Mortgagee
until date of repayment.

         14. Default:

             A. The occurrence of any one or more of the following after
expiration of applicable notice and cure periods, if any, at the option of
Mortgagee, shall constitute a default hereunder:

                (1) Failure of Mortgagor to pay any installment of principal or
interest, or any other sum, when it is due under the Note or this Mortgage
(provided that Mortgagee agrees, not more than once during any twelve (12) month
period during the term of this Mortgage to give Mortgagor notice of such failure
and allow five (5) days after the giving of such notice to cure such failure,
prior to same being an Event of Default); or

                (2) If any warranty, representation or other statement made by
Mortgagor in this Mortgage or in any other the other Loan Documents is
materially false, incorrect, incomplete or misleading; or
<PAGE>

                (3) Mortgagor's non-performance of or noncompliance with any of
the other agreements, conditions, covenants, provisions or stipulations
contained in the Note or in this Mortgage or any of the other Loan Documents
executed in connection with the Loan within thirty (30) days (or such longer
period as may be required, provided Mortgagor commences to cure such
non-performance or non-compliance within such thirty (30) day period and
thereafter proceeds with all due diligence and in good faith to complete such
performance or cure such non-compliance) after having received notice thereof
from Mortgagee; or

                (4) If Mortgagor shall make an assignment for the benefit of
creditors, or shall admit in writing its inability to pay its debts as they
become due, or shall file a petition in bankruptcy, or shall be adjudicated a
bankrupt or insolvent, or shall file a petition seeking any relief under any
present or future statute, law or regulation, relating to bankruptcy or
insolvency or shall file an answer admitting or not contesting the material
allegations of a petition filed against it in any such proceeding, or if
Mortgagor shall seek or consent to or acquiesce in the appointment of any
trustee, receiver, custodian, conservator, sequestrator or similar judicial
representative by whatever name of Mortgagor of any material part of its
properties not dismissed within sixty (60) days of such appointment; or

                                        5


<PAGE>
                (5) If within sixty (60) days after the commencement of any
proceeding against Mortgagor seeking any relief under any present or future
statute, law or regulation relating to bankruptcy or insolvency, such proceeding
shall not have been dismissed, or if, within sixty (60) days after the
appointment without the consent or acquiescence of Mortgagor, of any trustee,
receiver, custodian, conservator, sequestrator or similar judicial
representative by whatever name of Mortgagor or of any material part of its
properties, such appointment shall not have been vacated; or

                (6) If a final judgment for the payment of money in excess of
$20,000 shall be rendered against Mortgagor and, within thirty (30) days after
the entry thereof, such judgment shall not have been discharged, bonded-over or
execution thereof stayed pending appeal, or if, within thirty (30) days after
the expiration of any such stay, such judgment shall not have been discharged;
or

                (7) If Mortgagor incurs any debt in addition to the debt secured
by this Mortgage and the First Mortgage, which additional debt is secured by all
or any part of the Mortgaged Property without the prior written consent of
Mortgagee; or

                (8) If any default shall occur under the terms of the First
Mortgage.

             B. Upon the occurrence of any default hereunder, Mortgagee may give
written notice thereof to Mortgagor, and upon receipt of such written notice,
Mortgagor shall have thirty (30) days within which to cure any such default. The
continuance of any default after said notice and the elapsing of thirty (30)
days, without cure, shall be deemed an "Event of Default" hereunder; provided,
however, that if such default is not susceptible of cure within said thirty (30)
day period but is susceptible of cure within a reasonable period of time, then
said cure period shall be extended for a reasonable period of time, so long as
Mortgagor commences its cure within said thirty (30) day period and diligently
prosecutes the same to completion. In the case of the occurrence of a default
under either Subparagraph 14A(1) or 14A(2) above, such shall constitute an
"Event of Default" hereunder without the need for Mortgagee to provide notice
thereof to Mortgagor, anything to the contrary herein notwithstanding.

         15. Remedies:

             A. Subject to the terms of the First Mortgage and the Subordination
Agreement, if applicable, upon the happening of any Event of Default, the entire
unpaid balance of principal, accrued interest and all other sums secured by this
Mortgage shall become immediately due and payable, at the option of Mortgagee,
without further notice or demand.

             B. When the entire indebtedness shall become due and payable,
either because of maturity or because of the occurrence of any Event of Default,
or otherwise, then forthwith, subject to the First Mortgage and the
Subordination Agreement:

                (1) Foreclosure: Mortgagee may institute an action of mortgage
foreclosure, or take such other action at law or in equity for the enforcement
of this Mortgage and realization on the mortgage security or any other security
herein or elsewhere provided for, as the law may allow, and may proceed therein
to final judgment and execution for the entire unpaid balance of the Loan, with
interest at the rate stipulated in the Note, together with all other sums due by
Mortgagor in accordance with the provisions of the Note and this Mortgage,
including all sums which may have been loaned by Mortgagee to Mortgagor after
the date of this Mortgage, and all sums which may have been advanced by
Mortgagee for taxes, water or sewer rents, other lienable charges or claims,
insurance or repairs or maintenance, and all costs of suit. Mortgagor authorizes
Mortgagee, at Mortgagee's option, to foreclose this Mortgage subject to the
rights of any tenants of the Mortgaged Property; provided, however, that all
leases executed subsequent to the recordation of this Mortgage shall at all
times be subject and subordinate to this Mortgage and to all the terms and
conditions of this Mortgage and to the rights and liens of the holder of this
Mortgage and to all renewals, modifications, consolidations, replacements and
extensions thereof. The failure to make any such tenants parties defendant to
any such foreclosure proceedings and to foreclose their rights will not be, nor
be asserted by Mortgagor to be, a defense to any proceedings instituted by
Mortgagee to recover the indebtedness secured hereby or any deficiency remaining

<PAGE>

unpaid after the foreclosure sale of the Mortgaged Property; however, nothing
herein contained shall prevent Mortgagor from disputing in any proceedings the
amount of the deficiency or the sufficiency of any bid at such foreclosure sale
or that the failure to foreclose any such tenants adversely affects the value of
the Mortgaged Property. Upon any such foreclosure sale, Mortgagee may bid for
and purchase the Mortgaged Property and, upon compliance with the terms of sale,
may hold, retain, possess and dispose of the Mortgaged Property in its own
absolute right without further accountability.

                (2) Possession: Mortgagee may enter into possession of the
Mortgaged Property, with appropriate legal action, or, in the alternative,
Mortgagee shall be entitled as of right to appointment of a receiver without
regard to the solvency of Mortgagor or any other person liable for the debt
secured hereby, and regardless of whether Mortgagee has an adequate remedy at
law; either Mortgagee or said receiver, as the case may be, may (to the extent
permitted by law) rent the Mortgaged Property, or any part thereof, for such
term or terms and on such other terms and conditions as Mortgagee or such
receiver may see fit, collect all rentals (which terms, "rentals", shall also
include sums payable for use and occupation) and, after deducting all costs of
collection and administration expense, apply the net

                                        6


<PAGE>



rentals to the payment of taxes, water, and sewer rents, other lienable charges
and claims, insurance premiums and all other carrying charges, and to the
maintenance, repair or restoration of the Mortgaged Property, or in reduction of
the principal or interest, or both, hereby secured, in such order and amounts as
Mortgagee or said receiver may elect.

                (3) Receiver: Mortgagee, without regard to the value or
occupancy of the Mortgaged Property or the solvency of Mortgagor, of all or any
part of the Loan, with or without notice to Mortgagor, shall be entitled as a
matter of right, if it so elects, to the appointment of a receiver to enter upon
and take possession of the Mortgaged Property and to collect all rents,
revenues, issues, income, products and profits thereof and apply the same as the
court may direct. The receiver shall have all rights and powers permitted under
the laws of the state where the Mortgaged Property is located and such other
powers as the court making such appointment shall confer. The expenses,
including reasonable receiver's fees, attorney's fees, costs and agent's
compensation, incurred pursuant to the powers herein contained shall be secured
by this Mortgage. The right to enter and take possession of and to manage and
operate the Mortgaged Property, and to collect the rents, issues and profits
thereof, whether by a receiver or otherwise, shall be cumulative to any other
right or remedy hereunder or afforded by law, and may be exercised concurrently
therewith or independently thereof. Mortgagee shall be liable to account only
for such rents, issues and profits as are actually received by Mortgagee.
Notwithstanding the appointment of any receiver or other custodian, Mortgagee
shall be entitled as pledgee to the possession and control of any cash,
deposits, or instruments at the time held by, or payable or deliverable under
the terms of this Mortgage to Mortgagee.

             C. Subject to the Subordination Agreement, Mortgagee shall have the
right, from time to time, to bring an appropriate action to recover any sums
required to be paid by Mortgagor under the terms of this Mortgage, as they
become due, without regard to whether or not the principal indebtedness or any
other sums secured by the Note and this Mortgage shall be due, and without
prejudice to the right of Mortgagee thereafter to bring an action to foreclose
this Mortgage, or any other action, for any default by Mortgagor existing at the
time the earlier action was commenced.

             D. The Mortgaged Property, if sold pursuant to any writ or order of
execution issued on a judgment obtained by virtue of the Note or this Mortgage,
or pursuant to any other judicial proceedings under this Mortgage or the Note,
may be sold in one parcel, as an entirety, or in such parcels, and in such
manner or order as Mortgagee, in its sole discretion, may elect.

             E. Subject to the Subordination Agreement, Mortgagee shall have the
power and authority to institute and maintain at any time and from time to time
any suits and proceedings as Mortgagee may deem advisable: (1) to prevent any
impairment of the Mortgaged Property by any acts which may be unlawful or any
violation of this Mortgage, (2) to preserve or protect its interest in the
Mortgaged Property, and (3) to restrain the enforcement of or compliance with
any legislation or other governmental enactment, rule or order that may be
unconstitutional or otherwise invalid, if the enforcement of or compliance with
such enactment, rule or order might impair the security hereunder or be
prejudicial to Mortgagee's interest.

             F. Upon request or demand of Mortgagee and following the occurrence
of an Event of Default, subject to the First Mortgage and the Subordination
Agreement, Mortgagor shall, at its expense, assemble the personal property
forming part of the Mortgaged Property and make it available to Mortgagee at a
convenient place acceptable to Mortgagee. Mortgagor shall pay to Mortgagee, on
demand, any and all expenses, including attorneys' fees, incurred or paid by
Mortgagee in protecting its interest in such property and in enforcing its
rights hereunder with respect to such property. Any notice of sale, disposition
or other intended action by Mortgagee with respect to such property sent to
Mortgagor in accordance with the provisions hereof at least five (5) days prior
to such action, shall constitute reasonable notice to Mortgagor. The proceeds of
any disposition of such property, or any part thereof, may be applied by
Mortgagee to the payment of the indebtedness secured hereby in such priority and
proportions as Mortgagee in its discretion shall deem proper.
<PAGE>

             G. Subject to the First Mortgage and the Subordination Agreement,
Mortgagee shall have the right in its sole and absolute discretion to apply any
and all amounts received by Mortgagee in the exercise of any of Mortgagee's
rights and/or remedies hereunder or under any of the other Loan Documents, in
such order and in such amounts as Mortgagee may elect, against: (1) any amounts
payable by Mortgagor hereunder or under any of the other Loan Documents, and/or
(2) accrued and unpaid interest and/or (3) the outstanding principal balance of
the Loan.

             H. Neither Mortgagor nor any other person now or hereafter
obligated for payment of all or any part of the sums now or hereafter secured by
this Mortgage shall be relieved of such obligation by reason of the failure of
Mortgagee to comply with any request of Mortgagor or of any other person so
obligated to take action to foreclose on this Mortgage or otherwise enforce any
provisions of this Mortgage or the Note, or by reason of the release, regardless
of consideration, of all or any part of the security held for the indebtedness
secured by this Mortgage, or by reason of any agreement or stipulation between
any subsequent owner of the Mortgaged Property and Mortgagee extending the time
of payment or modifying the terms of this Mortgage or the Note without first
having obtained the consent of Mortgagor or such other person; and, in the
latter event, Mortgagor and all such other persons shall continue to be liable
to

                                        7


<PAGE>
make payments according to the terms of any such extension or modification
agreement, unless expressly released and discharged in writing by Mortgagee. No
release of all or any part of the security as aforesaid shall in any way impair
or affect the lien of this Mortgage or its priority over any subordinate lien.

             16. Counsel Fees: If Mortgagee becomes a party to any suit or
proceeding affecting the Mortgaged Property or title thereto, the lien created
by this Mortgage or Mortgagee's interest therein (including any proceeding in
the nature of eminent domain), or if following the occurrence of an Event of
Default, Mortgagee engages counsel to collect any of the indebtedness or to
enforce performance of the agreements, conditions, covenants, provisions or
stipulations of this Mortgage, the Note or any of the other Loan Documents,
Mortgagee's costs, expenses and reasonable fees for legal counsel, whether or
not suit is instituted, shall be paid to Mortgagee by Mortgagor, on demand, with
interest at the rate provided in the Note, and until paid they shall be deemed
to be part of the indebtedness evidenced by the Note and secured by this
Mortgage.

             17. Notices: All notices permitted or required under this Mortgage
or Note shall be in writing, and shall be sent by certified mail, return receipt
requested, postage prepaid or prepaid nationally recognized overnight carrier
service with receipt required, addressed to the addressee at the address set
forth above, or at such other address as the addressee may hereafter designate
to the other party in writing.

             18. Amendment: This Mortgage cannot be changed or amended except by
agreement in writing signed by the party against whom enforcement of the change
is sought.

             19. Parties Bound: This Mortgage shall be binding upon and inure to
the benefit of the parties hereto and their respective heirs, personal
representatives, successors and assigns. For purposes of this Mortgage, the
neuter shall include the masculine and feminine, and the singular shall include
the plural and the plural the singular, as the context may require.

             20. Interest Rate: Notwithstanding any provision contained in this
Mortgage or in the Note secured hereby, Mortgagor's liability for interest shall
not exceed the limits now imposed by the applicable usury law. If any clause in
the Note, this Mortgage or any of the other Loan Documents requires interest
payments in excess of the highest rate permitted by the applicable usury law,
the clause in question shall be deemed to require such payment at the highest
interest rate allowed by the applicable usury law.

             21. Prepayment: The obligation secured hereby may be prepaid in
full or in part at any time without penalty. No sums prepaid may be re-borrowed
or re-advanced.

             22. Financial Statements: Mortgagor covenants to furnish to
Mortgagee at any time upon request, Mortgagor's then current Form 1OK/10Q.

                 Mortgagor also agrees to make its books and accounts relating
to the Mortgaged Property available for inspection by Mortgagee or its
representatives upon request.

                 Following the occurrence of an Event of Default, Mortgagee
may, at it option, require (1) within ninety (90) days after the close of each
fiscal year of Mortgagor, current, complete, signed, financial statements
prepared in accordance with generally accepted accounting principles by, and
certified by, an independent certified public accountant (and in form and
content satisfactory to Mortgagee) for Mortgagor and each guarantor and/or
surety of the Loan; and (2) within forty-five (45) days of each fiscal quarter,
interim statements compiled by such independent certified public accountant in
accordance with generally accepted accounting principles.

             23. No Waiver: Any failure by Mortgagee to insist upon the strict
performance by Mortgagor of any of the terms and provisions hereof shall not be
deemed to be a waiver of any of the terms and provisions hereof, and Mortgagee,
notwithstanding any such failure, shall have the right thereafter to insist upon
the strict performance by Mortgagor of any and all of the terms and provisions
hereof to be performed by Mortgagor. Acceleration of maturity, once claimed
hereunder by Mortgagee, may, at the option of Mortgagee, be rescinded by written
acknowledgment to that effect by Mortgagee, but tender and acceptance of partial
payments alone shall not in any way affect or rescind such acceleration of
maturity.

             24. No Obligation to Marshal Assets: Neither Mortgagor nor the
holder of any mortgage, lien or other encumbrance affecting all or a part of the
Mortgaged Property which is inferior to the lien of this Mortgage shall have any
right to require Mortgagee to apply any amounts received by it to the payment of
any particular principal indebtedness in preference to any other principal
indebtedness secured hereby, and neither Mortgagor nor any such holder shall
have any right to require Mortgagee to marshal assets.

             25. Mortgagee Appointed Attorney-in-Fact: Mortgagor hereby
irrevocably appoints Mortgagee as its attorney-in-fact, in its name and stead,
solely to make and execute all conveyances, leases, assignments and transfers of
all or any part of the Mortgaged Property sold pursuant to foreclosure or other
proceedings, and Mortgagor shall join in the execution of any such instrument of
conveyance, assignment or transfer, but such execution by Mortgagor shall not be
necessary in order for such conveyance, lease, assignment or transfer to be
valid and effective in all respects.

             26. Compliance with Environmental Requirements: Mortgagor covenants
that:

                A. Mortgagor shall operate the Mortgaged Property or cause it to
be operated in compliance with all applicable laws of the state and federal
governments and all applicable rules and regulations promulgated by the New
Jersey Department of Environmental Protection (the "Department") or any
successor agency thereto. Mortgagor shall have the right in good faith to
contest or appeal from such laws, ordinances and regulations and any decision
adverse to Mortgagor based thereon, but all costs, fees and expenses incurred in
connection with such proceedings shall be borne by Mortgagor.

                B. The term "Hazardous Substances", as used herein shall mean
Hazardous Substances or Hazardous Wastes as such terms are defined in N.J.S.A.
58:10-23.11b(k) and N.J.A.C. 7:1E-1.3 and/or those elements or compounds which
are contained in the list of hazardous substances covered by the following
federal laws: Comprehensive Environmental Response, Compensation and Liability
Act of 1980, 42 U.S.C.A. 9601 et seq.; the Superfund Amendments and
Reauthorization Act of 1987; the Resource Conservation and Recovery Act of 1976,
42 U.S.C.A. 6901 et seq.; the Clean Water Act, 42 U.S.C.A. 7401 et seq.; the
Water Pollution Control Act, N.J.S.A. 58:10A-1 et seq., and all other similar
existing and future federal, state and municipal statutes, laws and ordinances
governing the environment, all as amended from time to time, together with all
rules and regulations issued or promulgated pursuant to or in connection with
any of the foregoing.

                C. Mortgagor shall not cause or permit to exist, as a result of
an intentional or unintentional action or omission on its part, a Release of
Hazardous Substances into any of the Protected Areas, unless said Release of
Hazardous Substances is pursuant to and in compliance with the conditions of a
permit issued by the appropriate federal or state governmental authorities.

                D. In the event that there shall be filed a lien against the
Mortgaged Property or any part thereof (I) by the U.S. Environmental Protection
Agency or (ii) by the Department, pursuant to and in accordance with the
provisions of N.J.S.A. 58:10-23.11f(f), as a result of the chief executive of
the New Jersey Spill Compensation Fund having expended monies from said fund to
pay for Damages and/or Cleanup and Removal Costs arising from an intentional or
unintentional action or omission of Mortgagor or any previous owner and/or
operator of the Mortgaged Property, and resulting in the Release of Hazardous
Substances into any of the Protected Areas, then Mortgagor shall, within thirty
(30) days from the date that Mortgagor is given notice that the lien has been
placed against any part or all of the Mortgaged Property, or within such shorter
period of time in the event that the State of New Jersey has commenced steps to
cause the Mortgaged Property to be sold pursuant to such lien, either (I) pay
the claim and remove the lien from the Mortgaged Property, or (ii) furnish (a) a
bond satisfactory to the title insurance company and Mortgagee in the amount of
the claim out of which the lien arises, (b) a cash deposit in the amount of the
claim out of which the lien arises, or (c) other security reasonably
satisfactory to Mortgagee in an amount sufficient to discharge the claim out of
which the lien arises (subject to Mortgagee's agreement, which agreement shall
not be unreasonably withheld or delayed, that the commitment of any reputable
title insurance company affirmatively to insure over or omit such claim shall
constitute such reasonably satisfactory security).

                E. Should Mortgagor cause or permit any intentional or
unintentional action or omission resulting in the Release of Hazardous
Substances into any of the Protected Areas, without having obtained a permit
issued by the appropriate governmental authorities, Mortgagor shall promptly
comply with the provisions of the New Jersey Spill Compensation and Control Act,
N.J.S.A. 58:10-23.11 et seq.

                F. If Mortgagor obtains, gives or receives notice of any Release
of Hazardous Substances or threat thereof at the Mortgaged Property, or receives
any notice of violation, request for information or notification that it is
potentially responsible for investigation or cleanup of environmental conditions
at the Mortgaged Property, demand letter or complaint, order, citation, or other
notice with regard to any Release of Hazardous Substances or any other
environmental matter affecting the Mortgaged Property or Mortgagor's interest
therein (an "Environmental Complaint") from any person or entity, including the
Department or the U.S. Environmental Protection Agency (either, the
"Authority"), then Mortgagor shall, within five (5) business days, give written
notice of same to Mortgagee detailing the facts and circumstances giving rise to
the Release of Hazardous Substances or Environmental Complaint. Such information
is to be provided to allow Mortgagee to protect its security interest in the
Mortgaged Property.
<PAGE>

                G. Mortgagor shall promptly forward to Mortgagee copies of any
request for information, notification of potential liability, demand letter
relating to potential responsibility with respect to the investigation or
cleanup of Hazardous Substances at any other site owned, operated or used by
Mortgagor to dispose of Hazardous Substances and shall continue to forward
copies of communications regarding such claims to Mortgagee until the claim is
settled. Mortgagor shall promptly forward to Mortgagee a copy of any filing
relating to the Release of Hazardous Substances at any other property owned or
leased by Mortgagor that Mortgagor is required to file under any state or local
environmental law, regulation or ordinance. Such information is to be provided
to allow Mortgagee to protect its security interest in the Mortgaged Property.

                H. If Mortgagor shall fail to respond promptly to any Release of
Hazardous Substances, Environmental Complaint or the presence of any Hazardous
Substances affecting the

                                        9


<PAGE>
Mortgaged Property, whether or not the same originates or emanates from the
Mortgaged Property or any other real estate, and/or if Mortgagor shall fail to
comply with any of the requirements of any federal or state environmental law or
regulation or local ordinance, Mortgagee may, at its election, but without the
obligation to do so after notice and no cure by Mortgagor within five (5) days:
(i) give such notices, and/or (ii) enter onto the Mortgaged Property after
reasonable notice to Mortgagor and take such actions as Mortgagee deems
reasonably necessary or advisable to clean up, remove, mitigate or otherwise
deal with any Release of Hazardous Substances, the presence of Hazardous
Substances or any Environmental Complaint. All reasonable costs and expenses
incurred by Mortgagee in the exercise of any such rights, including any sums
paid in connection with any judicial or administrative investigation or
proceeding, fines, penalties, fees for legal counsel and other professionals,
together with interest thereon at the default rate stipulated in the Note, and
if not specified therein, then at the then applicable rate of interest under the
Note, from the date of payment by Mortgagee, shall be immediately due and
payable by Mortgagor to Mortgagee, and until paid, shall be added to and become
a part of the indebtedness under the Note and shall be secured by the lien of
this Mortgage.

                I. Promptly upon the written request of Mortgagee, which written
request may be made by Mortgagee from time to time, Mortgagor shall provide
Mortgagee, at Mortgagee's initial expense (to be reimbursed by Mortgagor to
Mortgagee, immediately upon demand, if such assessment or audit reveals that any
Release of Hazardous Substance or other failure or default under this Article,
has occurred), an environmental site assessment or environmental audit report
issued in favor of Mortgagee and its counsel and prepared by an environmental
engineering firm acceptable, in the reasonable opinion of Mortgagee, to assess
with a reasonable degree of certainty the existence of a Release of Hazardous
Substances and the potential costs in connection with abatement, cleanup or
removal of any Hazardous Substances found on, under, at or within the Mortgaged
Property; provided that:

                    (1) If such estimates, individually or in the aggregate,
exceed $100,000.00, Mortgagee shall have the right to require Mortgagor to post
a bond to secure payment of these costs and expenses; and

                    (2) If the Release of Hazardous Substances is the subject of
any governmental inquiry, investigation or audit, then the provisions of the
preceding subsection shall be suspended during any such governmental action, and
Mortgagor shall be subject to any requirement imposed as a result of such
governmental action.

                J. In addition to the Events of Default set forth elsewhere in
this Mortgage, the filing by any Authority of an Environmental Complaint or
expenditure of money by any Authority to respond to a Release of Hazardous
Substances or Environmental Complaint at the Mortgaged Property (an "Action")
shall constitute an Event of Default under this Mortgage; provided, however,
such Action shall not constitute an Event of Default if, within thirty (30) days
of the date of notice to Mortgagor of such Action, Mortgagor demonstrates to the
reasonable satisfaction of Mortgagee that it has commenced and is diligently
pursuing either: (a) cure or correction of the event which constitutes the basis
for the Action, including, as necessary, payment of any claims and removal of
any lien imposed and continues diligently to pursue such cure or correction to
completion, or (b) institutes proceedings for an injunction, a restraining order
or other appeal procedure seeking to prevent such Authority from enforcing such
Action or to defend against the enforcement of such Action. Mortgagor shall post
a bond, letter of credit or other security, in form, substance, and amount
acceptable to Mortgagee and the Authority or entity seeking to enforce the
Action, to secure the proper and complete cure or correction of the event which
constitutes the basis for the Action. Subject to Mortgagee's agreement, which
agreement shall not be unreasonably withheld or delayed, the commitment of any
reputable title insurance company to affirmatively insure over or to omit such
lien shall constitute such reasonably satisfactory security.

                K. Except with respect to any occurrence prior to July 19, 1996,
and except with respect to any act or omission of Mortgagee after taking
possession of the Mortgaged Property, Mortgagor shall defend and indemnify
Mortgagee and hold Mortgagee harmless from and against all loss, liability,
damages and expenses, claims, costs, fines, penalties, including fees for legal
counsel and other professionals, suffered or incurred by Mortgagee, whether as
holder of this Mortgage, as a mortgagee in possession, or as
successor-in-interest to Mortgagor, by foreclosure deed or deed in lieu of
foreclosure, under or on account of any environmental statute, law, ordinance or

<PAGE>

order including the assertion of any lien thereunder, with respect to any
Release of Hazardous Substances, the presence of any Hazardous Substances
affecting the Mortgaged Property, whether or not the same originates or emanates
from the Mortgaged Property, including any loss of value of the Mortgaged
Property as a result of the foregoing so long as no such loss, liability, damage
and expense is attributable to any Release of Hazardous Substances resulting
from actions on the part of Mortgagee. Mortgagor's obligations under this
Article shall arise upon the discovery of the presence of any Hazardous
Substances at the Mortgaged Property, whether or not any federal, state, or
local environmental agency has taken or threatened any action in connection with
the presence of any Hazardous Substances. Mortgagor's obligation hereunder shall
survive the termination of this Mortgage.

             27. Condominium Regime: Mortgagor covenants and agrees not to
submit any part of the Mortgaged Property to a condominium regime without the
prior written approval of Mortgagee. If Mortgagee does grant such approval,
Mortgagee shall automatically have the right, but not the obligation,

                                       10


<PAGE>
to succeed to Mortgagor as developer or grantor under any master deed subjecting
the Mortgaged Property to a condominium regime.

             28. Intentionally Deleted.

             29. Intentionally Deleted.

             30. Purchase Agreements: Mortgagor hereby represents that there are
no purchase agreements or agreements to sell all or any part of the Mortgaged
Property now in effect.

             31. Intentionally Deleted.

             32. Bankruptcy Waiver: Mortgagor agrees that, in consideration of
the recitals and mutual covenants contained herein, and for other good and
valuable consideration, if Mortgagor or any general partner of Mortgagor shall
(I) file with any bankruptcy court of competent jurisdiction or be the subject
of any petition under Title 11 of the U.S. Code, as amended, (ii) be the subject
of any order for relief issued under such Title 11 of the U.S. Code, as amended,
(iii) file or be the subject of any petition seeking any reorganization,
arrangement, composition, readjustment, liquidation, dissolution, or similar
relief under any present or future federal or state act or law relating to
bankruptcy, insolvency, or other relief for debtors, (iv) have sought or
consented to or acquiesced in the appointment of any trustee, receiver,
conservator, or liquidator, (v) be the subject of any order, judgment, or decree
entered by any court of competent jurisdiction approving a petition filed
against such party for any reorganization, arrangement, composition,
readjustment, liquidation, dissolution, or similar relief under any present or
future federal or state act or law relating to bankruptcy, insolvency, or relief
for mortgagors, Mortgagor shall not assert or request any other party to assert
that the automatic stay provided by Section 362 of Title 11 of the U.S. Code
(the "Bankruptcy Code") shall operate or be interpreted to stay, interdict,
condition, reduce or inhibit the ability of Mortgagee to enforce any rights it
has by virtue of this Mortgage and all documents executed by Mortgagor in
connection herewith, or at law or in equity, or any other rights Mortgagee has,
whether now or hereafter acquired, against Mortgagor or against any collateral
for the loans evidenced by the Note, including, but not limited to the Mortgaged
Property. Specifically, without limiting the foregoing, in the event of any such
voluntary or involuntary bankruptcy filing following the execution and delivery
of this Mortgage and all documents executed by Mortgagor in connection herewith,
Mortgagee shall be entitled, and Mortgagor irrevocably consents, to an order
granting relief from any and all stays, including the automatic stay imposed by
Section 362 of the Bankruptcy Code or equitable relief under Section 105 of the
Bankruptcy Code, so as to permit Mortgagee to foreclose upon the Collateral and
to exercise any and all other rights and remedies of Mortgagee under this
Mortgage, any of such documents, or at law or in equity, and Mortgagor hereby
irrevocably waives any right to object to such relief.

             33. Recourse: Except as hereinafter set forth, Mortgagor shall not
have any personal liability for the payment or performance of any obligations
under the Note and in the event of a default under the Note, Mortgagee will look
solely to the Mortgaged Property and the rents, issues and profits thereof and
any other collateral specifically pledged, assigned or granted by Mortgagor as
security therefor, and any judgment obtained against Mortgagor shall so note by
its terms or as otherwise permissible by law. Notwithstanding the foregoing, in
the event of a default hereunder or under the Note, this obligation shall be
recourse to Mortgagor in an amount which is the difference between $3,000,000
and that portion of the recourse obligation from Mortgagor to Summit Bank
(pursuant to a Promissory Note in an amount not to exceed $9,777,240 of even
date herewith (the "Summit Note")) which is not credited by Summit Bank under
the Summit Note upon an event of default (as defined under the Summit Note) by
Mortgagor under the Summit Note (e.g., if Summit Bank utilizes $2,000,000 of the
recourse amount as a portion of or as all of its remedy under the Summit Note,
as the case may be, after an event of default under the Summit Note, the Note to
Mortgagee shall be recourse in the amount of $1,000,000). In no event, however,
shall (i) this obligation be recourse to Mortgagor in an amount greater than the
total amount owing by Mortgagor under the Note, nor (ii) the total recourse to
Mortgagor pursuant to the Note and the Summit Note exceed $3,000,000.

             34. Severability: In the event any clause, provision or term of
this Mortgage shall be found by a court of competent jurisdiction to be void or
unenforceable, such finding shall not be construed to affect the validity of the
remaining terms and conditions hereof and such remaining terms and conditions
shall remain in full force and effect.
<PAGE>

             35. Modification: The parties to this Mortgage may agree to change
the interest rate, due date or other term or terms of this Mortgage or the Note.
If the parties agree to a change, which change is a "modification" as defined in
N.J.S.A. 46:9-8.1 et seq., this Mortgage shall be subject to the priority
provisions of that law.

             36. Captions: The captions preceding the text of the paragraphs or
subparagraphs of this Mortgage are inserted only for convenience or reference
and shall not constitute a part of this Mortgage, nor shall they in any way
affect its meaning, construction or effect.

             37. Governing Law: This Mortgage and the performance of Mortgagor's
obligations hereunder shall be governed by the laws of the State of New Jersey.

             38. Venue: The parties hereby irrevocably and unconditionally agree
that any suit, action or other legal proceeding arising out or in connection
with this Mortgage, or the obligations secured hereby, shall be brought in the
courts of record of the State of New Jersey or the courts of the United States

                                       11


<PAGE>



located in said state, consents to jurisdiction of each such court in any such
suit, action or proceeding, and waive any objection to the venue of any such
suit, action or proceeding in any of such courts.

             39. WAIVER OF JURY TRIAL: TO THE EXTENT PERMITTED BY LAW, THE
PARTIES HEREBY WAIVE THEIR RESPECTIVE RIGHTS TO TRIAL BY JURY IN ANY LITIGATION
BETWEEN MORTGAGOR AND MORTGAGEE ARISING OUT OF OR IN CONNECTION WITH THE LOAN,
THIS MORTGAGE AND ANY OF THE OTHER LOAN DOCUMENTS. MORTGAGOR ACKNOWLEDGES THE
IMPORTANCE OF THIS RIGHT AND MAKES A KNOWING WAIVER THEREOF IN CONSIDERATION OF
THE WILLINGNESS OF MORTGAGEE TO MAKE THE LOAN TO IT.

             IN WITNESS WHEREOF, this Mortgage has been duly executed as of the
day and year first above written.

correct and complete copies of all lease agreements affecting any portion of the
Real Property and Improvements. To the best of the Borrower's knowledge based

                  (n) Management Agreements. There is no management agreement in
effect with respect to the management or operation of the Real Property and

maintain the Real Property and Improvements as an office building in all
respects in compliance with all subdivision, zoning, building, and other
applicable laws, ordinances, rules and regulations.

                  (b) Leases. The Borrower shall not enter into any New Lease or
similar agreement for space comprising any portion or all of the Real Property
and Improvements without in each case using the standard form of lease agreement
attached hereto as

                                       10


<PAGE>



Exhibit C and obtaining the Bank's prior written approval of all of the terms
and conditions thereof, which approval shall not be unreasonably withheld or
delayed. Once any such lease or similar agreement is approved, the Borrower
shall not amend, modify or cancel such lease or agreement without in each case
obtaining the Bank's prior written approval.

                  (c) Management Agreements. The Borrower shall not enter into
any management agreement with respect to all or any portion of the Real Property
and Improvements without in each case obtaining the Bank's prior written
approval, which shall not be unreasonably withheld or delayed so long as there
is no continuing event of default in existence under any of the Loan Documents.
With respect to any such approved management agreement, (i) there shall be no
amendment or modification thereof without in each case obtaining the prior
written approval of the Bank, and (ii) the lien and priority of payments under
such management agreement shall be under and subject and subordinate to payments
under the Loan pursuant to a subordination agreement among the Borrower, the
manager and the Bank or other documentation satisfactory in form and substance
to the Bank.

                  (d) Status of Title to Real Property and Improvements. Except
for Permitted Transfers (as hereinafter defined), the Borrower shall not
transfer control or ownership of the Real Property and Improvements or any part
thereof, directly or indirectly, voluntarily or involuntarily, without the prior
written approval of the Bank. Other than the Seller Mortgage, the Borrower shall
not create or permit to exist any lien, encumbrance or security interest
(whether consensual or otherwise) in favor of any third party with respect to
the Real Property and Improvements or any item of property, whether or not a
fixture, installed on the Real Property and Improvements or stored thereat and
the Borrower shall keep all such property free from any such lien, encumbrance
or security interest other than those created in favor of the Bank as
contemplated herein and liens for taxes not yet due and payable. In general, the
Borrower shall keep the title to the Real Property and the Improvements free of
any matter which would, at the time of completion of the Tenant Improvements,
prevent any title insurance company from certifying the lien of any mortgage to
be executed in favor of a permanent lender or other mortgagee in substitution
for or in payment of the Loan, as other than a good and valid first lien upon
the Real Property and the Improvements.

                  (e) Mechanic's Liens and Other Encumbrances. The Borrower
shall pay, discharge or obtain release bonds from a reputable surety company
satisfactory to the Bank for any mechanic's liens or other encumbrances which
may be filed or recorded against the Real Property or Improvements within ten
(10) days after it receives notice thereof, from the Bank or

                                       11


<PAGE>



otherwise. In the event that the Borrower shall fail to pay or discharge any
such mechanic's lien or other encumbrance, the Bank, in addition to such other
rights as may be available to it, may pay and discharge such mechanic's lien or
other encumbrance or deposit in escrow an amount sufficient to do so or cause a
mechanic's lien release bond to be issued with respect thereto and pay such
amounts as may be necessary in connection therewith, and all amounts so paid or
deposited shall be treated as an advance of the Loan from the Bank to the
Borrower.

                  (f) Environmental Matters. The Borrower will not, and will use
reasonable efforts not to, permit any tenant or other occupant of the Real
Property or Improvements to, store, use, generate, treat or dispose of any
Hazardous Substances or Wastes on the Real Property or Improvements except in de
minimus quantities and in accordance with applicable laws. The Borrower promptly
shall advise the Bank in writing of and with respect to any pending or known
threatened claim, demand, action or notice by any governmental authority or
third party relating to any Hazardous Substances or Wastes affecting the Real
Property or Improvements or the discovery or determination of the existence of
any Hazardous Substances or Wastes or Wetlands on the Real Property or
Improvements. The Bank shall have the right to join in or participate in any
legal proceedings or actions initiated in connection with any Hazardous
Substances, Wastes or Wetlands affecting the Real Property or Improvements. The
Borrower shall reimburse the Bank for reasonable attorneys' fees and costs in
connection therewith and the Borrower shall indemnify, defend and hold harmless
the Bank from and against any claim, demand, loss or liability, including but
not limited to costs of remedial action, response costs, personal injury and
property damage, directly or indirectly arising out of or attributable to the
use, generation, deposit, storage, release, discharge, disposal, burial,
dumping, spilling, leaking or other presence of Hazardous Substances or Wastes
on, under or affecting the Real Property or Improvements or arising as the
result of the existence of Wetlands on the Real Property or Improvements. The
foregoing indemnity shall specifically survive the repayment of the Loan and the
satisfaction of the Mortgage. The Borrower shall not, without obtaining the
Bank's prior written consent, which consent shall not be unreasonably withheld
or delayed so long as there is no continuing event of default then in existence
under any of the Loan Documents, enter into any settlement agreement, consent
decree or other compromise in respect to any Hazardous Substances, Wastes or
Wetlands affecting the Real Property or Improvements.

                  (g) Additional Financing. Except for the Seller Loan, the
Borrower shall not incur any additional indebtedness secured by any lien or
security interest on the Real Property and Improvements or any other property

passage of time or giving of notice or both would become an event of default
under any of the Loan Documents, and (G) each and all of the representations and
warranties set forth in paragraph 2 hereof continue to be true. The Bank
reserves the right to approve the form and content of each Application and to
verify the representations therein by an inspection of the Real Property and
Improvements. Each Application shall be subject to approval by the Bank
Consultant (as hereinafter defined).

                           (iv) The Bank shall have reviewed and approved the
identity of the contractor and, if applicable, the architect to be retained by
the Borrower, the plans and specifications, and budget, with respect to the
Tenant Improvements under the New Lease, each such approval not to be
unreasonably withheld or delayed.

                           (v) The Borrower shall have received, and the Bank
shall have reviewed and approved, all necessary and appropriate licenses,
permits and approvals, including without limitation building permits, for the
construction of the Tenant Improvements with respect to the New Lease.

                           (vi) The Bank shall have the right to retain an
architect or engineer of its selection to act as the Bank's consultant (the
"Bank Consultant") in connection with the construction of the Tenant
Improvements, to analyze all pertinent data relating to the construction of the
Tenant Improvements and make periodic inspections to verify the progress of
construction of the Tenant Improvements.

         6. Limitation of the Bank's Liability; Indemnity.

                  (a) Although the Bank and its agents may inspect the course of
construction and other matters pertaining to the Tenant Improvements, such
inspections are solely for the protection of the Bank as lender, and the
Borrower hereby confirms that the Bank is not making and will not be deemed to
make any representations or warranties as to any matters pertaining to the
Tenant Improvements by reason of such inspections.

                  (b) The rights and benefits of this Agreement shall not inure
to the benefit of any third party, except as provided in paragraph 10(e) of this
Agreement. Notwithstanding anything to the contrary contained in this Agreement
or in any of the other Loan Documents, or any conduct or course of conduct by
the Borrower or the Bank or their respective affiliates, agents or employees,
neither this Agreement nor any such Loan Documents shall be construed as
creating any rights, claims or causes of action against the Bank in favor of any
other person or entity other than the Borrower.

                  (c) Subject to the provisions of paragraph 9 hereof and only
so long as the Bank has not assumed possession and caused the same, the
Borrower, for itself and all those claiming under or through it, agrees to
protect, indemnify, defend and hold harmless the Bank, its directors, officers
and employees, from and against any and all liability, expense, or damage of any
kind or nature and from any suits, claims or demands, including reasonable legal
fees and expenses, arising out of this Agreement or in connection herewith
unless and except arising solely as a result of the Bank's gross negligence or
willful misconduct or actions of the Bank following its assumption of possession
of the Real Property and Improvements. This obligation specifically shall
survive the repayment of the Loan as to any such liability, expense, damage,
suit, claim or demand that arises, or the allegations or rights with respect
thereto which arise, prior to the repayment of the Loan.

         7. Maximum Rate of Interest on Loan. Notwithstanding anything to the
contrary contained herein or in any other document executed in connection with
the Loan, the effective rate of interest on the Loan shall not exceed the
maximum effective rate of interest permitted by applicable law or regulation.
The Borrower hereby agrees to give the Bank written notice in the event that the
Borrower has actual knowledge that any interest payment made to the Bank with
respect to this Loan will cause the total interest payments collected in any one
year to be usurious under applicable law, and the Bank hereby agrees not to
collect knowingly any interest from the Borrower in the form of fees or
otherwise which will render this Loan usurious. In the event that such interest
would be usurious in the Bank's opinion, the Bank reserves the right to reduce
the interest payable by the Borrower. This provision shall survive closing
hereunder and the repayment of the Loan.

         8. Defaults.

                  (a) Events of Default. The occurrence of any one or more of
the following events, after the expiration of any applicable notice and/or cure
period specifically provided for herein, shall, at the sole option of the Bank,
constitute an "event of default" hereunder:

                           (i) The Borrower shall fail to pay any regularly
scheduled installment of principal and/or interest due to the Bank under the
Note when the same shall become due and payable (including payment of the Loan
on the Maturity Date (as defined in the Note)) or the Borrower shall fail to
make any other payment due under any of the Loan Documents within fifteen (15)
days after notice thereof from the Bank;

                           (ii) Except as otherwise provided for herein, the
Borrower shall fail to observe or perform any of the covenants or

                                       21


<PAGE>



agreements on its part to be observed or performed under this Agreement or under
any of the other Loan Documents within thirty (30) days after written notice
from the Bank of such non-compliance, provided that if such non-compliance
cannot reasonably be cured within such thirty day period but the Borrower
undertakes within such thirty day period and thereafter diligently pursues the
curing of such non-compliance, then the period within which the Borrower shall
cure such non-compliance shall be extended to sixty (60) days after the original
written notice from the Bank of such non-compliance;

                           (iii) Any representation or warranty of the Borrower
under the Note or under any of the other Loan Documents shall be untrue in any
material respect;

                           (iv) Any event of default, after the expiration of
any applicable notice and/or cure period specifically provided for therein,
shall occur under any of the other Loan Documents or under any documents
evidencing or securing the Seller Loan;

                           (v) The Borrower shall apply for or consent to the
appointment of a receiver, trustee or liquidator of itself or any of its
property, admit in writing its inability to pay its debts as they mature, make a
general assignment for the benefit of creditors, be adjudicated a bankrupt,
insolvent or file a voluntary petition in bankruptcy, or a petition or an answer
seeking reorganization or an arrangement with creditors or to take advantage of
any bankruptcy, reorganization, insolvency, readjustment of debt dissolution or
liquidation law or statute, or an answer admitting the material allegations of a
petition filed against it in any proceeding under any such law, or if action
shall be taken by the Borrower for the purpose of effecting any of the
foregoing;

                           (vi) Any order, judgment or decree shall be entered
by any court of competent jurisdiction, approving a petition seeking
reorganization of the Borrower or all or a substantial part of the assets of the
Borrower, or appointing a receiver, sequestrator, trustee or liquidator of the
Borrower or any of its property and such order, judgment or decree shall
continue unstayed and in effect for a period of thirty (30) days; or

                           (vii) The Improvements shall be materially injured or
destroyed by fire or other casualty for which the cost of restoration is not
fully insured or, if not fully insured, the Borrower has failed to deposit with
the Bank the difference between the insurance proceeds received and the cost of
restoration, or in lieu thereof, has failed to agree with the Bank to provide
such funds or, in connection with such agreement, has failed to provide the Bank
with reasonable assurances that

                                       22


<PAGE>



such funds are available, all in accordance with the terms of the
Mortgage.

                  (b) Acceleration and Remedies. Upon the occurrence of any
event of default hereunder, in addition to any other rights or remedies
available to it hereunder or under any other Loan Document or at law or in
equity, subject however to the limitations set forth in paragraph 9 hereof, the
Bank may exercise any or all of the following rights and remedies in such order
and at such time or times as it may deem necessary or appropriate:

                           (i) declare the outstanding principal balance of the
Loan, together with all accrued and unpaid interest thereon and all other sums
due hereunder or under any of the other Loan Documents, to be immediately due
and payable in full; and/or

                           (ii) set off all property of the Borrower now or
hereafter at any time in its possession in any capacity whatsoever including,
but not limited to, any balance or share of any deposit, trust or agency
account, as to all of which property the Borrower hereby grants the Bank a lien
and security interest.

                  (c) Remedies Cumulative, etc.

                           (i) No right or remedy conferred upon or reserved to
the Bank under any of the Loan Documents, or with respect to any guaranty of
payment of the Loan or of performance of any of the Borrower's obligations under
any of the Loan Documents or any collateral securing the payment of the Loan
under any of the Loan Documents (such guaranty and such other collateral,
collectively, the "Collateral"), now or hereafter existing at law or in equity
or by statute or other legislative enactment, is intended to be or shall be
deemed exclusive of any other such right or remedy, and each and every such
right or remedy shall be cumulative and concurrent, and shall be in addition to
every other such right or remedy, and may be pursued singly, concurrently,
successively or otherwise, at the sole discretion of the Bank, and shall not be
exhausted by any one exercise thereof but may be exercised as often as occasion
therefore shall occur. The Bank acknowledges that there is no independent
guaranty agreement with respect to the Loan in existence on the date of this
Agreement. No act (or failure to act) of the Bank shall be deemed or construed
as an election to proceed under any one such right or remedy to the exclusion of
any other such right or remedy; furthermore, each such right or remedy of the
Bank shall be separate, distinct and cumulative and none shall be given effect
to the exclusion of any other. The failure to exercise or delay in exercising
any such right or remedy, or the failure to insist upon strict performance of
any term of any of the Loan Documents, shall not be construed as a waiver or
release of the same, or of any event of default

                                       23


<PAGE>



thereunder, or of any obligation or liability of the Borrower thereunder.
Nothing herein, however, shall be construed to prevent the Bank from waiving any
condition, obligation or default it should so elect. In the event of such
election by the Bank, any waiver, in order to be effective, must be in writing
and signed by the Bank, and any such waiver shall be strictly limited in its
effect to the condition, obligation or default specified therein and shall not
extend to any subsequent condition, obligation or default or impair any right of
the Bank with respect thereto.

                           (ii) The recovery of any judgment by the Bank and/or
the levy of execution under any judgment shall not affect in any manner or to
any extent, liens or other security interests in any Collateral, or any rights,
remedies or powers of the Bank under any of the Loan Documents or with respect
to any Collateral, but such liens and security interests, and such rights,
remedies and powers of the Bank shall continue unimpaired as before. Further,
the entry of any judgment by the Bank shall not affect in any way the interest
rate payable under any of the Loan Documents on any amounts due to the Bank, but
interest shall continue to accrue on such amounts at the Default Rate (as
hereafter defined).

                           (iii) The Borrower hereby waives presentment, demand,
notice of nonpayment, protest, notice of protest, or other notice of dishonor,
and any and all other notices in connection with any default in the payment of,
or any enforcement of the payment of, the Loan except as may be otherwise
specifically set forth herein. To the extent permitted by law, the Borrower
waives the right to any stay of execution and the benefit of all exemption laws
now or hereafter in effect. The Borrower further waives and releases all
procedural errors, defects and imperfections in any proceedings instituted by
the Bank under the terms of any of the Loan Documents or with respect to any
Collateral.

                           (iv) The Borrower agrees that the Bank may release,
compromise, forbear with respect to, waive, suspend, extend or renew any of the
terms of the Loan Documents (and the Borrower hereby waives any notice of any of
the foregoing), and that the Loan Documents may be amended, supplemented or
modified by the Bank and the other signatory parties and that the Bank may
resort to any Collateral in such order and manner as it may think fit, or accept
the assignment, substitution, exchange, pledge, or release of all or any portion
of any Collateral, for such consideration, or none, as it may require, without
in any way affecting the validity of any liens upon or other security interests
in the remainder of any such Collateral (or the priority thereof or the position
of any subordinate holder of any lien or other security interest with respect
thereto); and any action taken by the Bank pursuant to the foregoing shall in no

                                       24


<PAGE>



way be construed as a waiver or release of any right or remedy of the Bank, or
of any event of default, or of any liability or obligation of the Borrower,
under any of the Loan Documents.

                  (d) Default Rate. Following the occurrence of any event of
default and continuing either until such event of default is cured and that fact
acknowledged by the Bank or until the principal sum then outstanding under the
Note and all other sums payable under the Loan Documents are paid in full, the
principal sum outstanding under the Note shall bear interest at rate equal to
the annual interest rate then applicable under paragraph 1 of the Note plus four
percent (4%) per annum, which rate shall change if, when and as such interest
rate changes ("Default Rate"), and shall be secured by the Mortgage and all
other Collateral.

                  (e) Cost and Expenses. The Borrower shall pay upon demand all
reasonable costs and expenses (including all amounts paid to attorneys,
accountants, real estate brokers and other advisors employed by the Bank)
incurred by the Bank in the exercise of any of its rights, remedies or powers
under any of the Loan Documents, or as a secured or unsecured creditor, as the
case may be, of the Borrower in any federal or state bankruptcy proceedings, or
with respect to any Collateral with respect to such event of default, and any
amount thereof not paid promptly following demand therefor together with
interest thereon at the Default Rate from the date of such demand, shall become
part of the Loan and shall be secured by the Mortgage and all other Collateral.
In connection with and as part of the foregoing, in the event that any of the
Loan Documents is placed in the hands of an attorney for the collection of any
sum payable thereunder, the Borrower agrees to pay reasonable attorneys' fees
for the collection of the amount being claimed under such Loan Document, as well
as all costs, disbursements and allowances provided by law, the payment of which
sums shall be secured by the Mortgage and all other Collateral.

                  (f) Jurisdiction; Venue. The Borrower agrees that any action
or proceeding against it to enforce the Loan may be commenced in state or
federal court in Camden County in the State of New Jersey, and the Borrower
waives personal service of process and agrees that a summons and complaint
commencing an action or proceeding in any such court shall be properly served if
served by registered or certified mail in accordance with the notice provisions
set forth herein, and the Borrower expressly waives any and all defenses to an
exercise of personal jurisdiction by any such court.

                  (g) WAIVER OF TRIAL BY JURY. THE BORROWER HEREBY KNOWINGLY,
VOLUNTARILY AND INTENTIONALLY WAIVES ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN
RESPECT OF ANY LITIGATION BASED UPON OR ARISING OUT OF, UNDER OR IN CONNECTION
WITH THIS LOAN

                                       25


<PAGE>



AGREEMENT, ANY OF THE OTHER LOAN DOCUMENTS, OR ANY COURSE OF CONDUCT, COURSE OF
DEALING, STATEMENTS (WHETHER VERBAL OR WRITTEN) OR ACTIONS OF THE BORROWER OR
THE BANK. THIS PROVISION IS A MATERIAL INDUCEMENT FOR THE BANK TO MAKE THE LOAN.

         9. Limited Liability of the Borrower. Except as hereinafter set forth,
the Borrower shall not have any personal liability for the payment of the Loan
or for the payment of any sum or performance of any obligation under any of the
Loan Documents, and in the event of a default under this Agreement or any of the
other Loan Documents the Bank will look solely to the Real Property and
Improvements, the rents, issues and profits thereof and any other Collateral
specifically pledged, assigned or granted by the Borrower to the Bank as
security for the Loan pursuant to this Agreement or any of the other Loan
Documents, and any judgment obtained against the Borrower shall so note by its
terms or as otherwise permissible by law. Subject to the aforesaid limitation,
nothing herein contained shall be construed to prevent the Bank from exercising
and enforcing any other remedy against the Borrower or any other person or
entity allowed at law or in equity or by any statute or by the terms of this
Agreement or any of the other Loan Documents or any other deed of trust,
mortgage, security agreement, assignment of leases and rents, guaranty or any
other security instrument of any kind now or hereafter securing payment of the
Loan. In addition, notwithstanding anything to the contrary contained herein,
the Borrower shall indemnify and hold the Bank harmless against, and shall be
personally liable and obligated to the Bank for:

                  (a) the completion of construction of the Tenant Improvements
in accordance with the respective deadlines therefor in the New Leases free and
clear of any and all mechanics liens and any other liens and encumbrances;

                  (b) the payment on a current basis of all monthly installments
of principal and interest with respect to the Acquisition Portion of the Loan
and interest with respect to the Tenant Improvement Portion of the Loan (but
excluding therefrom the entire unpaid principal balance of the Loan becoming due
as a result of maturity or acceleration of the Loan to the extent not
constituting a regular monthly installment);

                  (c) the principal amount of the Loan to the extent of
$3,000,000, which may be allocated between the Acquisition Portion of the Loan
and Tenant Improvement Portion of the Loan as the Bank shall determine in its
sole discretion, and which shall not be reduced by any payments on account of
the Acquisition Portion of the Loan or Tenant Improvement Portion of the Loan by
the Borrower or by any other person or entity, whether by payments in the
ordinary course or by mortgage foreclosure or otherwise; and

                                       26


<PAGE>



                  (d) an amount equal to all loss, liability, damage, cost and
expense suffered or incurred by the Bank in any way arising out of, resulting
from or relating to any one or more of the following: (i) any fraud or willful
material misrepresentation committed by the Borrower; (ii) any retention by the
Borrower of rental income, security deposits, or similar income of the Real
Property and Improvements after an event of default has occurred under the Loan
Documents to the extent of any such retention; (iii) any real property taxes or
assessments accrued prior to the Bank's acquisition of ownership of the Real
Property and Improvements following a default by the Borrower under the Loan;
(iv) removal or failure to replace any personal property securing the Loan,
other than in the ordinary course of the Borrower's business; (v) misapplication
of insurance or condemnation proceeds relating to the Real Property and
Improvements; (vi) failure to maintain hazard or liability insurance relating to
the Real Property and Improvements, in accordance with the Loan Documents; (vii)
the presence of any Hazardous Substances or Wastes which may affect the Real
Property and Improvements, or any misrepresentation or breach of any covenants
or indemnities by the Borrower set forth in the Loan Documents with respect to
Hazardous Substances or Wastes; (viii) any transfer of the Real Property and
Improvements or any portion thereof other than Permitted Transfers; (ix) any
indebtedness secured by a mortgage covering the Real Property and Improvements
other than the Seller Loan; (x) any bankruptcy, reorganization, insolvency,
readjustment of debt, dissolution, liquidation or receivership proceedings
instituted by or against the Borrower, unless and except to the extent that such
proceedings are withdrawn, dismissed or discharged within ninety (90) days or
unless the Bank obtains title to the Real Property and Improvements within nine
(9) months; and (xi) all fees and costs, including reasonable attorney fees,
incurred in enforcing and collecting the foregoing.

         10. Miscellaneous

                  (a) Time of the Essence. All dates and times for the
performance of the Borrower's obligations set forth herein shall be deemed to be
of the essence of this Agreement.

                  (b) Broker's and Finder's Fees. The Borrower represents and
warrants that it has not dealt with or through any broker or other intermediary
in connection with the Loan except for CB Commercial and the Borrower agrees to
indemnify, defend and hold the Bank harmless from and against any loss,
liability or damage (including attorneys' fees and expenses) arising from any
claim for a brokerage fee or finder's fee in connection with the Loan, including
any claims by CB Commercial.

                  (c) Publicity. The Bank may, at its option and in such manner
as it may determine, announce and publicize the

                                       27


<PAGE>



source of the financing for the Real Property and Improvements at any time after
the date of this Agreement.

                  (d) Severability. In the event that for any reason one or more
of the provisions of this Agreement or their application to any person or
circumstance shall be held to be invalid, illegal or unenforceable in any
respect or to any extent, such provisions shall nevertheless remain valid, legal
and enforceable in all other respects and to such extent as may be permissible.
In addition, any such invalidity, illegality or unenforceability shall not
affect any other provision hereof, but this Agreement shall be construed as if
such invalid, illegal or unenforceable provision had never been contained
herein.

                  (e) Successors and Assigns. This Agreement inures to the
benefit of and binds the parties hereto and their respective heirs, personal
representatives, successors and assigns, as applicable, and the words "Borrower"
and "Bank" whenever occurring herein shall be deemed to include such respective
heirs, personal representatives, successors and assigns, as applicable. However,
the Borrower shall not voluntarily, or by operation of law, assign or transfer
any interest which it may have under this Agreement or convey the Real Property
and Improvements, or any part thereof, without the prior written approval of the
Bank. The Bank may assign or otherwise transfer the Loan and any or all of the
Loan Documents to any other person, and such other person shall thereupon become
vested with all of the benefits in respect thereof granted to the Bank herein or
otherwise. The Bank shall have the right to sell participations in the Loan to
any other persons or entities without the consent of or notice to the Borrower.
Without the consent of or notice to the Borrower, the Bank may disclose to any
prospective purchaser of any securities issued or to be issued by the Bank, and
any prospective or actual purchaser of any participation or other interest in
the Loan or any other loans made by the Bank to the Borrower, any financial or
other information, data or material in the Bank's possession relating to the
Borrower, the Loan or the Real Property and Improvements.

                      AMENDED AND RESTATED PROMISSORY NOTE

$9,777,140                                              Cherry Hill, New Jersey

                                                                   July 19, 1996

         FOR VALUE RECEIVED, BRANDYWINE REALTY TRUST, a Maryland real estate
investment trust with an office at Two Greentree Centre, Suite 100, Marlton, New
Jersey 08053 ("Maker"), promises to pay to the order of SUMMIT BANK, a New
Jersey state bank (formerly known as United Jersey Bank/South, N.A. and United
Jersey Bank) with an office at 1800 Chapel Avenue West, Cherry Hill, New Jersey
08002 ("Payee"), at such office of Payee or at such other place as Payee may
designate from time to time in writing, the principal sum of Nine Million Seven
Hundred Seventy-seven Thousand One Hundred Forty Dollars ($9,777,140) (or so
much thereof as has been advanced by Payee to or for the benefit of Maker
pursuant to a certain amended and restated loan agreement dated this date by and
between Maker and Payee (the "Loan Agreement")) lawful money of the United
States of America, together with interest thereon from the date hereof at the
rates hereinafter provided, and both payable as hereinafter provided. This Note
evidences an amended and restated loan ("Loan") being made by Payee to Maker
pursuant to the terms of the Loan Agreement, and reference thereto is made for
the background of and basis for the Loan. Capitalized terms not otherwise
defined herein shall have the meanings given them in the Loan Agreement.

         1. Interest Rate.

                  (a) The Acquisition Portion of the Loan shall bear interest on
the unpaid principal balance thereof outstanding from time to time at a fixed
annual rate of eight percent (8%). The Tenant Improvement Portion of the Loan
shall bear interest on the unpaid principal balance thereof outstanding from
time to time at an annual rate at all times equal to Payee's prime interest
rate, as announced from time to time by Payee ("Prime Rate"), plus one percent
(1%), such rate to change when and as the Prime Rate changes. It is understood
that the Prime Rate is not necessarily the most favorable interest rate offered
by Payee and that Payee prices loans at, above and below the Prime Rate.

                  (b) The annual interest rate shall be calculated on the basis
of a 360 day year and the actual number of days elapsed.

                  (c) Notwithstanding anything to the contrary contained
herein or in any other document executed in connection with the

                                        1


<PAGE>



Loan, the effective rate of interest hereunder shall not exceed the maximum
effective rate of interest permitted by applicable law or regulation. Maker
hereby agrees to give Payee written notice in the event Maker has actual
knowledge that any interest payment made to Payee with respect to this Note will
cause the total interest payments collected in any one year to be usurious under
applicable law, and Payee hereby agrees not to collect knowingly any interest
from Maker in the form of fees or otherwise which will render the Loan usurious.
In the event that such interest would be usurious in Payee's opinion, Payee
reserves the right to reduce the interest payable by Maker. This provision shall
survive the repayment of this Note.

         2. Payment Terms.

                  (a) (i) With respect to the Acquisition Portion of the Loan,
the unpaid principal balance thereof, together with interest thereon at the rate
applicable thereto under paragraph 1(a) hereof, shall be payable in monthly
installments beginning on August 19, 1996 and continuing on the same day of each
successive calendar month thereafter, each monthly installment to be in the
amount of Sixty-seven Thousand Eight Hundred Nine Dollars and Twenty-nine Cents
($67,809.29), which is based upon the stated principal amount of the Acquisition
Portion of the Loan, the interest rate applicable thereto pursuant to paragraph
1(a) hereof and a level payment direct reduction amortization schedule with a
term of 22 years and 6 months.

                      (ii) With respect to the Tenant Improvement Portion of the
Loan, interest only on the unpaid principal balance thereof shall be payable in
monthly installments on the nineteenth (19th) day of each month, beginning on
the first such date following the first advance of the Tenant Improvement
Portion of the Loan and continuing on the same day of each successive calendar
month thereafter.

                      (iii) The unpaid principal balance of this Note then
outstanding (including the Acquisition Portion of the Loan and the Tenant
Improvement Portion of the Loan) together with all accrued and unpaid interest
shall become due and payable on January 1, 1999 ("Maturity Date").

                  (b) Maker shall have the right at any time to prepay all or
any portion of the unpaid principal balance of this Note, provided that:

                           (i) There shall be a prepayment penalty or premium
with respect to any prepayment of the Acquisition Portion of the Loan in an
amount equal to one percent (1%) of the amount being prepaid; provided, however,
that there shall be no such

                                        2


<PAGE>



prepayment penalty or premium with respect to any prepayment (A) resulting from
Payee's disapproval of any merger or material change in the ownership of Maker
under paragraph 3(i) of the Loan Agreement, (B) resulting from the application
of insurance or condemnation proceeds pursuant to paragraphs 6 and 7,
respectively, of the Mortgage or (C) resulting from an acceleration of the
indebtedness evidenced by this Note pursuant to paragraph 10 hereof, and there
shall be no prepayment penalty or premium with respect to any prepayment of the
Tenant Improvement Portion of the Loan.

                           (ii) Any prepayment, whether voluntary or
involuntary, shall be applied first to any accrued and unpaid interest under the
Acquisition Portion of the Loan or Tenant Improvement Portion of the Loan,
whichever is the subject of such prepayment, up to the date of such prepayment
and then to any other sums which may be payable to Payee under the Loan
Documents up to the date of such prepayment and then to the outstanding
principal balance of the Acquisition Portion of the Loan or Tenant Improvement
Portion of the Loan, whichever is the subject of such prepayment, any such
prepayment applied to principal shall be applied to the principal portions of
installments due in the inverse order of their maturity, and the acceptance of
any such prepayment when there is an event of default in existence under any of
the Loan Documents shall not constitute a waiver, release or accord and
satisfaction thereof or of any rights with respect thereto by Payee.

         3. Security. This Note, and the due performance by Maker of all of its
obligations hereunder, is secured by, inter alia, (a) an amended and restated
mortgage and security agreement ("Mortgage") covering certain real property
located at 457 Haddonfield Road and 1700 Chapel Avenue, both in Cherry Hill
Township, Camden County, New Jersey ("Real Property"), and any and all
improvements now existing or hereafter constructed thereon ("Improvements"),
which Mortgage is being executed this date and shall be recorded forthwith, (b)
an amended and restated assignment of all of Maker's right, title and interest
in and to any and all present and future leases affecting the Real Property and
Improvements ("Assignment of Leases and Rents"), (c) an amended and restated
assignment of all of Maker's right, title and interest in and to all
construction contracts, architect's agreements, other contracts and agreements,
and any and all licenses, permits and approvals relating to the construction of
the Tenant Improvements, and all other documents and rights relating to the
construction of the Tenant Improvements ("Assignment of Contracts and Permits"),
and (d) security interests in certain personal property of Maker. Reference is
hereby made to the Loan Agreement and Mortgage for a full description of the
Real Property and Improvements and the

                                        3


<PAGE>



collateral pledged pursuant thereto, and the terms upon which this Note is
secured.

         This Note, the Loan Agreement, the Mortgage, the Assignment of Leases
and Rents, the Assignment of Contracts and Permits, and any other document
executed and delivered in connection with the Loan are hereinafter referred to
individually as a "Loan Document" and collectively as the "Loan Documents." Any
collateral securing any of Maker's obligations under any of the Loan Documents
are hereinafter referred to collectively as the "Collateral."

         4. Late Charge. In the event that any payment of principal or interest
due to Payee under this Note shall not be paid when due and shall remain unpaid
in excess of ten (10) days after the due date, in addition to and not in
limitation of any other rights or remedies which Payee may have in respect
thereof under any of the Bank Loan Documents or in respect of any Collateral,
Maker shall pay Payee on demand a "late charge" computed at the lesser of (a)
the rate of five cents ($.05) for each dollar (or part thereof) of any principal
or interest amount not paid within ten (10) days after its due date or (b) the
maximum amount or rate permitted by law, in order to cover the extra expense and
inconvenience to Payee in ensuring payment of such delinquent amount. Maker
acknowledges that its failure to pay any amount due under this Note within such
ten (10) day period will result in Payee incurring additional expense in
servicing the Bank Loan, the loss of the use of the money due and frustration to
Payee in meeting its loan commitments, that the damages to Payee in connection
with such late payment are extremely difficult and impractical to ascertain, and
that a sum equal to five cents ($.05) for each dollar which is not paid within
such ten (10) day period, subject to the foregoing limitation, is a reasonable
estimate of the damages incurred by Payee in connection with any such late
payment. The amount of any such "late charge" not paid promptly following demand
therefor shall be deemed outstanding and payable pursuant to this Note and
secured by the Mortgage.

         5. Events of Default. In addition to any other event referred to
herein, the occurrence of which, by the terms hereof, constitutes an event of
default hereunder, the occurrence of any one or more of the following events,
after the expiration of any applicable notice and/or cure period specifically
provided for herein, shall constitute an "event of default" hereunder:

                  (a) Maker shall fail to pay any regularly scheduled
installment of principal and/or interest due to Payee under this Note when the
same shall become due and payable (including payment of the Loan on the Maturity
Date) or Maker shall fail to

                                        4


<PAGE>



make any other payment due under any of the Loan Documents within fifteen (15)
days after notice thereof from Payee;

                  (b) Except as otherwise provided for in this Note, Maker shall
fail to observe or perform any of the covenants or agreements on its part to be
observed or performed under this Note or under any of the other Loan Documents
within thirty (30) days after written notice from Payee of such non-compliance,
provided that if such non-compliance cannot reasonably be cured within such
thirty day period but the Maker undertakes within such thirty day period and
thereafter diligently pursues the curing of such non-compliance, then the period
within which the Maker shall cure such non-compliance shall be extended to sixty
(60) days after the original written notice from the Payee of such
non-compliance;

                  (c) Any representation or warranty of Maker under this Note or
under any of the other Loan Documents shall be untrue in any material respect;

                  (d) Any event of default, after the expiration of any
applicable notice and/or cure period specifically provided for therein, shall
occur under the terms of any of the other Loan Documents;

                  (e) Maker shall apply for or consent to the appointment of a
receiver, trustee or liquidator of itself or any of its property, admit in
writing its inability to pay its debts as they mature, make a general assignment
for the benefit of creditors, be adjudicated a bankrupt, insolvent or file a
voluntary petition in bankruptcy, or a petition or an answer seeking
reorganization or an arrangement with creditors or to take advantage of any
bankruptcy, reorganization, insolvency, readjustment of debt, dissolution or
liquidation law or statute, or an answer admitting the material allegations of a
petition filed against it in any proceeding under any such law, or if action
shall be taken by Maker for the purpose of effecting any of the foregoing;

                  (f) Any order, judgment or decree shall be entered by any
court of competent jurisdiction, approving a petition seeking reorganization of
Maker or all or a substantial part of the assets of Maker or appointing a
receiver, sequestrator, trustee or liquidator of Maker or any of its property,
and such order, judgment or decree shall continue unstayed and in effect for any
period of thirty (30) days.

         6. Remedies. Upon the occurrence of any event of default, then the
entire unpaid principal sum hereunder plus all interest

                                        5


<PAGE>



accrued thereon plus all other sums due and payable to Payee under the Loan
Documents shall, at the option of Payee, become due and payable immediately
without presentment, demand, notice of nonpayment, protest, notice of protest or
other notice of dishonor, all of which are hereby expressly waived by Maker. In
addition to the foregoing, upon the occurrence of any event of default, subject
however to the limitations set forth in paragraph 11 hereof, Payee may forthwith
exercise singly, concurrently, successively or otherwise any and all rights and
remedies available to Payee under any of the Loan Documents or with respect to
any Collateral, or available to Payee by law, equity, statute or otherwise.

         7. Remedies Cumulative.

                  (a) No right or remedy conferred upon or reserved to Payee
under any of the Loan Documents, or with respect to any Collateral, or now or
hereafter existing at law or in equity or by statute or other legislative
enactment, is intended to be exclusive of any other right or remedy, and each
and every such right or remedy shall be cumulative and concurrent, and shall be
in addition to every other such right or remedy, and may be pursued singly,
concurrently, successively or otherwise, at the sole discretion of Payee, and
shall not be exhausted by any one exercise thereof but may be exercised as often
as occasion therefor shall occur. No act of Payee shall be deemed or construed
as an election to proceed under any one such right or remedy to the exclusion of
any other such right or remedy; furthermore, each such right or remedy of Payee
shall be separate, distinct and cumulative and none shall be given effect to the
exclusion of any other. The failure to exercise or delay in exercising any such
right or remedy, or the failure to insist upon strict performance of any term of
any of the Loan Documents, shall not be construed as a waiver or release of the
same, or of any event of default thereunder, or of any obligation or liability
of Maker thereunder.

                  (b) The recovery of any judgment by Payee and/or the levy of
execution under any judgment upon any Collateral shall not affect in any manner
or to any extent the lien of the Mortgage upon, or any security interest under
the Loan Agreement in such Collateral, or any rights, remedies or powers of
Payee under any of the Loan Documents or with respect to any Collateral, but
such lien and such security interest, and such rights, remedies and power of
Payee shall continue unimpaired as before. Further, the exercise by Payee of its
rights and remedies and the entry of any judgment by Payee shall not affect in
any way the interest rate payable hereunder or under any of

                                        6


<PAGE>



the other Loan Documents on any amounts due to Payee but interest shall continue
to accrue on such amounts at the Default Rate (as hereinafter defined).

                  (c) Maker hereby waives presentment, demand, notice of
nonpayment, protest, notice of protest or other notice of dishonor, and except
as may be stated herein any and all other notices in connection with any default
in the payment of, or any enforcement of the payment of, all amounts due under
the Loan Documents except as may be specifically set forth herein or therein. To
the extent permitted by law, Maker waives the right to any stay of execution and
the benefit of all exemption laws now or hereafter in effect. Maker further
waives and releases all procedural errors, defects and imperfections in any
proceedings instituted by Payee under the terms of any Loan Document or with
respect to any Collateral.

                  (d) Maker agrees that Payee may release, compromise, forbear
with respect to, waive, suspend, extend or renew any of the terms of the Loan
Documents (and Maker hereby waives any notice of any of the foregoing), and that
the Loan Documents may be amended, supplemented or modified by Payee and the
other signatory parties and that Payee may resort to any Collateral in such
order and manner as it may think fit, or accept the assignment, substitution,
exchange, pledge, or release of all or any portion of any Collateral, for such
consideration, or none, as it may require, without in any way affecting the
validity of any liens over or other security interest in the remainder of any
such Collateral (or the priority thereof or the position of any subordinate
holder of any lien or other security interest with respect thereto); and any
action taken by Payee pursuant to the foregoing shall in no way be construed as
a waiver or release of any right or remedy of Payee, or of any event of default,
or of any liability or obligation of the Maker, under any of the Loan Documents.

                  (e) Maker agrees that any action or proceeding against it to
enforce the Note may be commenced in state or federal court in Camden County in
the State of New Jersey, and Maker waives personal service of process and agrees
that a summons and complaint commencing an action or proceeding in any such
court shall be properly served if served by registered or certified mail in
accordance with the notice provisions set forth herein and Maker expressly
waives any and all defenses to an exercise of personal jurisdiction by any such
court.

                  (f) MAKER HEREBY KNOWINGLY, VOLUNTARILY AND INTENTIONALLY
WAIVES ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION
BASED UPON OR ARISING OUT OF, UNDER OR IN CONNECTION WITH THIS NOTE OR ANY OF
THE OTHER LOAN DOCUMENTS

                                        7


<PAGE>



OR ANY COURSE OF CONDUCT, COURSE OF DEALING, STATEMENTS (WHETHER VERBAL OR
WRITTEN) OR ACTIONS OF MAKER OR PAYEE. THIS PROVISION IS A MATERIAL INDUCEMENT
FOR PAYEE TO MAKE THE LOAN.

         8. Default Rate. Following the occurrence of any event of default and
continuing either until such event of default is cured and that fact
acknowledged by the Payee or until the principal sum then outstanding hereunder
and all other sums payable under the Loan Documents are paid in full, the
principal sum outstanding hereunder shall bear interest at rate equal to the
annual interest rate then applicable under paragraph 1 hereof plus four percent
(4%) per annum, which rate shall change if, when and as such interest rate
changes ("Default Rate"), and shall be secured by the Mortgage and all other
Collateral.

         9. Costs and Expenses. Following the occurrence of any event of
default, Maker shall pay upon demand all reasonable costs and expenses
(including all reasonable amounts paid to attorneys, accountants, real estate
brokers and other advisors employed by Payee and/or to any contractors for labor
and materials), incurred by Payee in the exercise of any of its rights, remedies
or powers under any of the Loan Documents or with respect to any Collateral with
respect to such event of default, and any amount thereof not paid promptly
following demand therefor shall be added to the principal sum hereunder and
shall bear interest at the Default Rate from the date of such demand until paid
in full, and shall be secured by the Mortgage and all other Collateral. In
connection with and as part of the foregoing, in the event that any of the Loan
Documents is placed in the hands of an attorney for the collection of any sum
payable thereunder, Maker agrees to pay reasonable attorneys' fees for the
collection of the amount being claimed under the Loan Document, as well as all
costs, disbursements and allowances provided by law, the payment of which sums
shall be secured by the Mortgage and all other Collateral. Nothing in this
paragraph 9 shall limit the obligation of Maker to pay any and all costs and
expenses for which Maker is otherwise liable under any of the Loan Documents.

         10. Mortgage Taxes, etc. Maker shall pay the cost of any revenue, tax
or other stamps now or hereafter required by the laws of the State of New Jersey
or the United States to be affixed to this Note or the Mortgage and if any taxes
are imposed under the laws of the State of New Jersey or the United States with
respect to debts secured by a mortgage, or with respect to evidences of
indebtedness so secured, Maker shall pay or reimburse Payee upon demand the
amount of such taxes without credit against any indebtedness by this Note. If
Maker does not

or may not do so, Payee may at its option accelerate the indebtedness evidenced
by this Note to maturity as in the case of default by Maker.

         11. Limited Liability of Maker. Except as hereinafter set forth, Maker
shall not have any personal liability for the payment of the Loan or for the
payment of any sum or performance of any obligation under any of the Loan
Documents, and in the event of a default under this Note or any of the other
Loan Documents Payee will look solely to the Real Property and Improvements, the
rents, issues and profits thereof and any other Collateral specifically pledged,
assigned or granted by Maker to Payee as security for the Loan pursuant to this
Note or any of the other Loan Documents, and any judgment obtained against Maker
shall so note by its terms or as otherwise permissible by law. Subject to the
aforesaid limitation, nothing herein contained shall be construed to prevent
Payee from exercising and enforcing any other remedy against Maker or any other
person or entity allowed at law or in equity or by any statute or by the terms
of this Note or any of the other Loan Documents or any other deed of trust,
mortgage, security agreement, assignment of leases and rents, guaranty or any
other security instrument of any kind now or hereafter securing payment of the
Loan. In addition, notwithstanding anything to the contrary contained herein,
Maker shall indemnify and hold Payee harmless against, and shall be personally
liable and obligated to Payee for:

                  (a) the completion of construction of the Tenant Improvements
in accordance with the respective deadlines therefor in the New Leases free and
clear of any and all mechanics liens and any other liens and encumbrances;

                  (b) the payment on a current basis of all monthly installments
of principal and interest with respect to the Acquisition Portion of the Loan
and interest with respect to the Tenant Improvement Portion of the Loan (but
excluding therefrom the entire unpaid principal balance of the Loan becoming due
as a result of maturity or acceleration of the Loan to the extent not
constituting a regular monthly installment);

                  (c) the principal amount of the Loan to the extent of
$3,000,000, which may be allocated between the Acquisition Portion of the Loan
and Tenant Improvement Portion of the Loan as Payee shall determine in its sole
discretion, and which shall not be reduced by any payments on account of the
Acquisition Portion of the Loan or Tenant Improvement Portion of the Loan by
Maker or by any other person or entity, whether by payments in the ordinary
course or by mortgage foreclosure or otherwise; and

                                        9


<PAGE>



                  (d) an amount equal to all loss, liability, damage, cost and
expense suffered or incurred by Payee in any way arising out of, resulting from
or relating to any one or more of the following: (i) any fraud or willful
material misrepresentation committed by Maker; (ii) any retention by Maker of
rental income, security deposits, or similar income of the Real Property and
Improvements after an event of default has occurred under the Loan Documents to
the extent of any such retention; (iii) any real property taxes or assessments
accrued prior to Payee's acquisition of ownership of the Real Property and
Improvements following a default by Maker under the Loan; (iv) removal or
failure to replace any personal property securing the Loan, other than in the
ordinary course of Maker's business; (v) misapplication of insurance or
condemnation proceeds relating to the Real Property and Improvements; (vi)
failure to maintain hazard or liability insurance relating to the Real Property
and Improvements, in accordance with the Loan Documents; (vii) the presence of

by Maker set forth in the Loan Documents with respect to Hazardous Substances or
Wastes; (viii) any transfer of the Real Property and Improvements or any portion
thereof other than Permitted Transfers; (ix) any indebtedness secured by a
mortgage covering the Real Property and Improvements other than the Seller Loan;
(x) any bankruptcy, reorganization, insolvency, readjustment of debt,
dissolution, liquidation or receivership proceedings instituted by or against
Maker, unless and except to the extent that such proceedings are withdrawn,
dismissed or discharged within ninety (90) days or unless Payee obtains title to
the Real Property and Improvements within nine (9) months; and (xi) all fees and
costs, including reasonable attorney fees, incurred in enforcing and collecting
the foregoing.

         12. Severability. In the event that for any reason one or more of the
provisions of this Note or their application to any person or circumstance shall
be held to be invalid, illegal or unenforceable in any respect or to any extent,
such provisions shall nevertheless remain valid, legal and enforceable in all
such other respects and to such extent as may be permissible. In addition, any
such invalidity, illegality or unenforceability shall not affect any other
provisions of this Note, but this Note shall be construed as if such invalid,
illegal or unenforceable provision had never been contained herein.

         13. Successors and Assigns. This Note inures to the benefit of Payee
and binds Maker, and their respective successors and assigns, and the words
"Payee" and "Maker" whenever occurring herein shall be deemed and construed to
include such respective successors and assigns, as applicable.

hereafter acquired by, or released to, Mortgagor or constructed, assembled or
placed by Mortgagor on the Real Property, and all conversions of the security
constituted thereby, immediately upon such acquisition, release, construction,
assembling, placement or conversion, as the case may be, and in each such case,
without any further mortgage, pledge, conveyance, assignment or other act by
Mortgagor, shall become subject to the lien of this Mortgage and Security
Agreement as fully and completely, and with the same effect, as though now owned
by Mortgagor and specifically described herein. Notwithstanding the foregoing,
Mortgagor shall, at its own cost, make, execute, acknowledge, deliver and record
any and all such further acts, deeds, conveyances, mortgages, notices of
assignment, transfers, assurances and other documents as Mortgagee shall from
time to time reasonably require for the better assuring, conveying, assigning,

Receivable, Securities, Deposits and Plans. Mortgagor shall, at its own cost and

<PAGE>



Mortgagee may reasonably require from time to time to perfect and maintain in
favor of Mortgagee a security interest under the Uniform Commercial Code in such
Equipment, Building Equipment, Intangibles, Awards, Insurance Policies, Leases
and Agreements, Income and Rents, Accounts Receivable, Securities, Deposits and
Plans. Without limiting the generality of any of the foregoing, Mortgagor hereby
irrevocably appoints Mortgagee attorney-in-fact for Mortgagor to execute,
deliver and file any of the documents referred to hereinabove for and on behalf
of Mortgagor following notice from Mortgagee to Mortgagor to execute such
documents and the failure by Mortgagor to do so within five (5) business days.

         PROVIDED ALWAYS, and these presents are upon this express condition,
that if Mortgagor or its successors or assigns shall well and truly pay or cause
to be paid unto Mortgagee, its successors or assigns, the Aggregate Debt secured
by this Mortgage and Security Agreement, and otherwise perform Mortgagor's
obligations under the Loan Documents, then this Mortgage and Security Agreement,
and the estate hereby granted, shall cease, determine and be void, and Mortgagee
shall furnish to Mortgagor a satisfaction of this Mortgage and Security
Agreement in proper form for recording, but Mortgagee shall not be required to
bear any expense or cost in connection with such satisfaction or the recording
thereof.

         THIS MORTGAGE AND SECURITY AGREEMENT also secures, inter alia, present
and future advances made by Mortgagee pursuant to the Loan Documents, including,
without limitation, advances made to enable completion of the Tenant
Improvements. The priority of such future advances shall relate back to the date
of this Mortgage and Security Agreement, or to such later date as required by
applicable law. This Mortgage and Security Agreement also secures advances made
by Mortgagee with respect to the Mortgaged Property for the payment of taxes,
assessments, maintenance charges, and insurance premiums, costs incurred by
Mortgagee for the protection of the Mortgaged Property or the lien of this
Mortgage and Security Agreement, and expenses incurred by Mortgagee by reason of
the occurrence of an event of default hereunder and the priority of such
advances, costs and expenses shall also relate back to the date of this Mortgage
and Security Agreement, or to such later date as required by applicable law.

         MORTGAGOR WARRANTS TO AND COVENANTS WITH Mortgagee as
follows:

         1. Title. As of the date hereof (a) Mortgagor has good and marketable
title to an indefeasible fee simple estate in the Mortgaged Property subject to
no lien, charge or encumbrance except such as are listed as exceptions to title
or exclusions

                                        5


<PAGE>



from coverage in the title insurance policy being issued by Lawyers Title
Insurance Corporation to Mortgagee concurrently with the recording of this
Mortgage and Security Agreement; (b) this Mortgage and Security Agreement is and
shall remain a valid and enforceable first lien on the Mortgaged Property
subject only to the matters referred to in subparagraph (a) hereof; (c)
Mortgagor shall preserve such title, and all of its rights in and to the
Mortgaged Property, and shall forever warrant and defend the validity and
priority of the lien hereof against the claims of all persons and entities
whomsoever, subject only to the matters referred to in subparagraph (a) hereof;
and (d) Mortgagor has full power and lawful authority to mortgage the Mortgaged
Property and grant a security interest therein in the manner and form herein
done or intended hereafter to be done.

         2. Payment and Performance. Mortgagor shall punctually pay or cause to
be paid the Aggregate Debt, in the amounts and at the times and places that the
same may be due, and perform and comply with all of the terms, covenants,
conditions and obligations contained in the Loan Documents.

         3. Taxes and Other Charges. Mortgagor shall pay all taxes of every kind
and nature (including real and personal property, income, gross receipts,
franchise, profits, sales and withholding taxes), all general and special
assessments, water and sewer rents and charges, and all levies, permits,
inspection and license fees and other public charges now or hereafter levied or
assessed against the Mortgaged Property as liens or assessments (hereinafter
individually called a "Tax" and collectively the "Taxes") as the same shall
become due and payable from time to time and before interest or penalties accrue
thereon; provided, however, that Mortgagor shall not be required to pay any Tax
to the extent that nonpayment thereof is permitted while the validity thereof is
being contested, so long as (a) Mortgagor notifies Mortgagee in writing of its
intention to contest the validity thereof, (b) the validity thereof is being
contested in good faith by Mortgagor and (c) Mortgagor deposits with Mortgagee
if Mortgagee so requests an amount reasonably deemed sufficient to make such
payment if the contest is unsuccessful. Notwithstanding the foregoing, Mortgagor
shall under no circumstances permit the Mortgaged Property to be sold or
advertised for sale for nonpayment of any Tax. Mortgagor shall not apply for or
claim any deduction from the taxable value of the Mortgaged Property because of
the existence of the Note or this Mortgage and Security Agreement. Subject to
Mortgagor's right to contest any Tax as hereinabove provided, Mortgagor shall
deliver to Mortgagee receipts evidencing the payment of such Tax on or before
the last day on which any Tax may be paid without interest or penalties or as
soon thereafter as such receipts are available.

         4. Insurance. Mortgagor shall keep the Improvements and the Equipment
continuously insured against loss or damage by fire (with extended coverage),
theft, vandalism, malicious mischief, sprinkler leakage, flood (if the Mortgaged
Property is located in a flood plain area) and such other hazards as Mortgagee
shall from time to time reasonably require in a total amount equal to the full
insurable value, as determined by the insurance company which shall issue such
insurance, or in any event not less than that amount below which any
co-insurance provisions would apply and not less than the then outstanding
amount of the Aggregate Debt. Mortgagor shall also carry appropriate insurance
applicable to the Mortgaged Property in connection with the construction work
upon the Mortgaged Property (whether or not such work is expensed or capitalized
by Mortgagor) as required in the Loan Agreement and in such amounts as may be
required by Mortgagee. Mortgagor shall also carry rental loss insurance and
comprehensive liability insurance (including bodily injury and property damage)
covering all operations of Mortgagor on the Mortgaged Property in such amounts
as may be reasonably required by Mortgagee. Any policy or policies with respect
to all of the abovementioned insurance (hereinafter called a "Policy") (a) shall
be issued by an insurer reasonably acceptable to Mortgagee (for these purposes,
Aetna Insurance Company is acceptable to Mortgagee), (b) shall contain, in the
case of the hazard insurance and rental loss insurance, a mortgagee clause
endorsement naming Mortgagee and its successors and assigns as a co-insured
thereunder, as its interests may appear, and, at Mortgagee's option, shall
contain a clause naming Mortgagee as an additional insured and/or loss payee,
(c) shall contain a provision that Mortgagee shall be given thirty (30) days'
prior written notice of material change or cancellation of said Policy and that
no such change or cancellation shall be effective as to Mortgagee in the absence
of such notice, and (d) shall contain such other provisions as shall from time
to time be reasonably required by Mortgagee. Any such Policy may provide for
customary "deductibles" provided the limits thereof are reasonably satisfactory
to Mortgagee. Not less than fifteen (15) days' prior to any date upon which any
premium for such insurance shall be due and payable, Mortgagor shall deliver to
Mortgagee satisfactory evidence that such premium has been paid, and further,
not less than fifteen (15) days' prior to the expiration date of any Policy,
Mortgagor shall deliver to Mortgagee satisfactory evidence of the renewal of
such Policy. In the event of the foreclosure of this Mortgage and Security
Agreement or other transfer of Mortgagor's interest in the Mortgaged Property in
satisfaction of the Aggregate Debt, all right, title and interest of Mortgagor
to any Policy then in force covering the Mortgaged Property (including any right
to any deferred premiums) shall pass to the transferee of the Mortgaged
Property.

         5. Tax and Insurance Escrow. Upon the written request of Mortgagee at
any time following the occurrence of an event of default hereunder, Mortgagor
shall pay to Mortgagee on the first day of each month a sum equal to one-twelfth
(1/12) of the amount of (a) all real estate taxes, water and sewer charges and
assessments, if any, as estimated from time to time by Mortgagee, becoming due
with respect to the Mortgaged Property on the next succeeding date upon which
the same shall be due and payable and (b) all premiums, computed on an annual
basis, for the insurance required to be carried pursuant to paragraph 4 hereof.
All such amounts (hereinafter, the "Escrows") shall be held by Mortgagee in such
manner as it sees fit without any obligation to invest the same or (if invested)
to account for any income or loss resulting therefrom; provided however, that if
and to the extent that Mortgagee is required under applicable law to invest the
Escrows for the benefit of Mortgagor, Mortgagee shall also have the right to
charge a reasonable service fee in connection therewith unless prohibited under
such law. The Escrows shall be applied to the payment of the respective items in
respect of which the Escrows were deposited, or at Mortgagee's option, to the
payment of any such items in such order of priority as Mortgagee shall
determine, as the same become due and payable. If, prior to the date upon which
any of the aforesaid items shall be due and payable, the amount of Escrows then
on deposit therefor shall be insufficient to pay such item, Mortgagor within
five (5) days after demand is made therefor shall deposit the amount of such
deficiency with Mortgagee. If there is an event of default hereunder, Mortgagee
may at its option apply the Escrows or any part thereof in payment of any unpaid
portion of the Aggregate Debt. If, when making any assignment of this Mortgage
and Security Agreement, the then Mortgagee shall pay over to its assignee the
then balance of the Escrows and such assigning Mortgagee shall have no further
obligation to Mortgagor with respect to such deposits.

         6. Casualty Loss. Mortgagor shall notify Mortgagee in writing
immediately upon the occurrence of any loss affecting the Mortgaged Property.
Mortgagor hereby directs any insurer to pay directly to Mortgagee any moneys
payable under any Policy, and Mortgagor hereby appoints Mortgagee as
attorney-in-fact to endorse any draft therefor. Sums paid to Mortgagee by any
insurer may be retained and applied by Mortgagee toward payment of the Aggregate
Debt (whether or not any portion thereof may then be due and payable) in such
priority and proportions as Mortgagee in its discretion shall deem proper, and
any sums not so applied, at the discretion of Mortgagee, may be paid, either in
whole or in part, to Mortgagor for such purposes and upon such conditions as
Mortgagee shall designate. Notwithstanding the

                                        8


<PAGE>



foregoing, upon the request of Mortgagor, Mortgagee shall make such sums
available to Mortgagor for repair and restoration of the damaged property,
provided that (a) there is not then in existence any uncured event of default
under any of the Loan Documents, (b) Mortgagor shall deposit with Mortgagee
prior to the commencement of any such repair or restoration an amount equal to
the difference between the estimated cost to repair the damaged property and the
sums made available to Mortgagee on account of such insurance, and (c) such
repair and restoration can be completed within one (1) year from the date of the
loss (but in no event later than the Maturity Date (as defined in the Note)).
The determination of the cost to repair the damaged property shall be made by
Mortgagee in consultation with an independent third party engineer selected by
Mortgagee and paid for by Mortgagor. If Mortgagee retains such insurance money
and applies the same toward payment of the Aggregate Debt in accordance with
this paragraph 6, the lien of this Mortgage and Security Agreement shall be
reduced only by the amount thereof retained by Mortgagee and actually applied by
Mortgagee in reduction of the Aggregate Debt.

         7. Condemnation. In the event that the whole or any material part of
the Mortgaged Property secured by this Mortgage and Security Agreement is
condemned or taken for any period of time, or there is any other injury to or
material decrease in value of the Mortgaged Property as a result of any public
or quasi-public authority or corporation exercising the power of eminent domain
or otherwise, all sums awarded as damages for such condemnation or taking to
which Mortgagor is entitled shall be paid over immediately to Mortgagee. Upon
the receipt thereof, Mortgagee may deduct and withhold from the amount actually
received any costs, charges or fees incurred by Mortgagee in connection with the
recovery of such award (hereinafter, "Mortgagee's Costs"), and thereafter
Mortgagee may apply all or any portion of the balance to the discharge of the
Aggregate Debt and, at the option of Mortgagee, may pay over any sums not so
applied to Mortgagor for the purpose of restoring or repairing the Mortgaged
Property or for any purpose or object satisfactory to Mortgagee, in which event
the Aggregate Debt shall not be reduced by that amount. Notwithstanding the
foregoing, in the event of a partial rather than complete condemnation of the
Mortgaged Property and upon the request of Mortgagor, Mortgagee shall make such
sums available to Mortgagor for repair and restoration of the damaged property,
provided that (a) there is not then in existence any uncured event of default
under any of the Loan Documents, (b) Mortgagor shall deposit with Mortgagee
prior to the commencement of any such repair or restoration an amount equal to
the difference between the cost to repair the damaged property and the sums made
available by Mortgagee on account of such insurance, (c) such repair and
restoration can be

                                        9


<PAGE>



completed within six (6) months from the date of the loss (but in no event later
than the Maturity Date) and (d) Mortgagee has determined that the condemnation
of the Mortgaged Property will not materially adversely affect the ownership and
operation of the Mortgaged Property for its current purpose as an office
building. Mortgagor hereby irrevocably appoints Mortgagee as attorney-in-fact
for Mortgagor for the purpose of collection of any or all proceeds available in
connection with the condemnation of the Mortgaged Property. If the Mortgaged
Property is transferred, through foreclosure or otherwise, prior to the receipt
by Mortgagee of such award of payment, Mortgagee shall have the right, whether
or not a deficiency judgment on the Note shall have been sought, recovered or
denied, to receive such award or payment, or a portion thereof sufficient to pay
the Aggregate Debt, whichever is less.

         8. Preservation of Lien; No Conveyance of Title.

                  (a) Mortgagor shall pay, from time to time as and when the
same shall become due, all claims and demands of any persons or entities which,
if unpaid, might result in or permit the creation of a lien on the Mortgaged
Property or any part thereof, and in general shall do or cause to be done
everything necessary so that the lien hereof shall be fully preserved and so
that there shall not be created, permitted or suffered to exist any lien,
encumbrance or charge affecting the Mortgaged Property other than those matters
referred to in paragraph 1(a) hereof which have been approved in writing by
Mortgagee, all at the sole cost of Mortgagor. At Mortgagee's election, and
without notice to Mortgagor, Mortgagee may make but is not obligated to make,
any payments which Mortgagor has failed to make under any prior lien, but such
payment by Mortgagee shall not release Mortgagor from Mortgagor's obligations or
constitute a waiver of Mortgagor's default hereunder. Any sum so expended by
Mortgagee shall be secured by this Mortgage and Security Agreement, together
with interest thereon at the rate stipulated in the Note from the date such
payment is made by Mortgagee until the date of repayment by Mortgagor.
Notwithstanding the foregoing, Mortgagor shall have the right, at its sole cost
and expense, to contest in good faith by any lawful means any such claims and
demands, provided that it notifies Mortgagee in writing of its intention to do
so and deposits with Mortgagee, if Mortgagee so requests, an amount deemed
reasonably sufficient by Mortgagee to satisfy such claims and demands if it is
ultimately determined that Mortgagor is responsible therefor.

                  (b) Mortgagor shall not convey or attempt to convey or permit
or suffer a conveyance or transfer of legal or equitable title to the Mortgaged
Property or any part thereof and whether such conveyance or transfer is
voluntary, involuntary, by

                                       10


<PAGE>



operation of law or otherwise, so long as any part of the Aggregate Debt remains
unpaid without the prior written consent of Mortgagee.

        9. Maintenance and Repair; Compliance with Laws and Regulations.
Mortgagor shall cause the Mortgaged Property to be maintained in good condition
and repair, reasonable wear and tear excepted. None of the Improvements,
Equipment or Building Equipment shall be removed, demolished, materially altered
or sold (except for normal replacement or upgrade of the Equipment), without the
prior written consent of Mortgagee. Subject to the release of the insurance
proceeds, Mortgagor shall promptly repair, replace or rebuild any part of the
Mortgaged Property which may be damaged or destroyed by any casualty or which
may be affected by any condemnation or eminent domain proceeding. Mortgagor
shall promptly comply with all laws, orders, ordinances, regulations,
restrictions and requirements of governmental authorities, of courts and of
insurance companies applicable to Mortgagor or affecting the Mortgaged Property,
or the use thereof. Mortgagor also shall promptly comply with the provisions of
any recorded covenants, conditions or restrictions to which the Mortgaged
Property or any part thereof may at any time be subject. Mortgagor shall not
cause or allow the construction or erection of any public, municipal or utility
improvements upon the Mortgaged Property other than those required by public
authorities, without the prior written consent of Mortgagee. Mortgagor shall not
drill or extract or enter into any lease for the drilling for or extraction of
oil, gas or other hydrocarbon substances or any mineral of any kind or character
on or from the Mortgaged Property or any part thereof without the prior written
consent of Mortgagee. Mortgagor shall not seek, make or consent to any change in
zoning or conditions of use of the Mortgaged Property which would impair the
ability of Mortgagor to operate the Real Property and Improvements as a first
class office building.

         10. Environmental Matters.

                  (a) To the best of Mortgagor's knowledge based upon the
Environmental Report and the Purchase Agreement, except as may be set forth in
the Environmental Report or the Purchase Agreement and except for the use and
storage of Hazardous Substances in de minimis amounts which are used in and
stored in compliance with all applicable laws and regulations, (i) the Mortgaged
Property has not been used for the generation, manufacture, storage or disposal
of, and there has not been transported to or from the Mortgaged Property, any
Hazardous Substances or Wastes, (ii) there are no Hazardous Substances or Wastes
present on the Mortgaged Property, (iii) the Mortgaged Property does not consist
in whole or in part of any soils or

                                       11


<PAGE>



vegetation that would be considered to be Wetlands, (iv) there has been no use
of the Mortgaged Property that may, under any federal, state or local law or
regulation, require any closure or cessation of the use of the Mortgaged
Property or impose upon Mortgagor or its successors any monetary obligations,
(v) no lien or superlien has been recorded, asserted or threatened against the
Mortgaged Property for any liability in connection with any environmental
contamination, and (vi) the Mortgaged Property is in compliance with all
federal, state or local laws and regulations relating to environmental matters.

                  (b) Mortgagor's knowledge with respect to environmental
matters affecting the Mortgaged Property is limited to such matters, if any,
which appear in the Environmental Report or Purchase Agreement.

                  (c) Mortgagor has not been identified in any litigation,
proceeding or investigation as a responsible party or potentially responsible
party for any liability for disposal or release of any Hazardous Substances or
Wastes.

                  (d) Mortgagor will not, and will use reasonable efforts not
to, permit any tenant or other occupant of the Mortgaged Property to, store,
use, generate, treat or dispose of any Hazardous Substances or Wastes on the
Mortgaged Property except in de minimus quantities and in accordance with all
applicable laws. Mortgagor promptly shall advise Mortgagee in writing of and
with respect to any pending or known threatened claim, demand, action or notice
by any governmental authority or third party relating to any Hazardous
Substances or Wastes affecting the Mortgaged Property or the discovery or
determination of the existence of any Hazardous Substances or Wastes or Wetlands
on the Mortgaged Property. Mortgagee shall have the right to join in or
participate in any legal proceedings or actions initiated in connection with any
Hazardous Substances, Wastes or Wetlands affecting the Mortgaged Property.
Mortgagor shall reimburse Mortgagee for reasonable attorneys' fees and costs in
connection therewith and Mortgagor shall indemnify, defend and hold harmless
Mortgagee from and against any claim, demand, loss or liability, including but
not limited to costs of remedial action, response costs, personal injury and
property damage, directly or indirectly arising out of or attributable to the
use, generation, deposit, storage, release, discharge, disposal, burial,
dumping, spilling, leaking or other presence of Hazardous Substances or Wastes
on, under or affecting the Mortgaged Property or arising as the result of the
existence of Wetlands on the Mortgaged Property. The foregoing indemnity shall
specifically survive the repayment of the Loan and the satisfaction of the
Mortgage, but shall not be applicable to any environmental matter first arising
subsequent to Mortgagor's

                                       12


<PAGE>



ownership of the Mortgaged Property. Mortgagor shall not, without obtaining
Mortgagee's prior written consent, enter into any settlement agreement, consent
decree or other compromise in respect to any Hazardous Substances, Wastes or
Wetlands affecting the Mortgaged Property.

         11. Leases. Except as otherwise provided in the Loan Agreement,
Mortgagor shall not enter into any lease or similar agreement for space in or on
the Mortgaged Property without in each case obtaining Mortgagee's prior written
approval of all the terms and conditions thereof and, once approved, Mortgagor
shall not amend, modify or cancel any such lease or similar agreement or assign
any amounts due thereunder without obtaining Mortgagee's prior written approval.

         12. Required Notice. Mortgagor shall give Mortgagee prompt written
notice of any action or proceeding purporting to affect the Mortgaged Property
of which it has actual knowledge including, without limitation, the following:
(a) a fire or other casualty causing damage to the Mortgaged Property; (b)
receipt of notice of condemnation of the Mortgaged Property or any part thereof;
(c) receipt of notice from any governmental authority relating to the structure,
use or occupancy of the Mortgaged Property; (d) receipt of any notice from any
tenant of all or any portion of the Mortgaged Property; (e) any change in the
occupancy of the Mortgaged Property; (f) receipt of any notice from the holder
of any lien or security interest in the Mortgaged Property; or (g) commencement
of any litigation affecting the Mortgaged Property. Mortgagee shall have the
right to appear in or defend any such action or proceeding to the same extent as
Mortgagor after written notice to Mortgagor. Furthermore, Mortgagee shall have
the right to bring any action or proceeding, in the name and on behalf of itself
or Mortgagor, which Mortgagee, in its discretion, feels should be brought to
protect its interest in the Mortgaged Property or any part thereof.

         13. Mortgagee's Right to Cure. Mortgagee shall have the right, but not
the obligation, at Mortgagee's election and after written notice to Mortgagor,
to cure any default by Mortgagor under any of the Loan Documents or under any
mortgage or with respect to any security interest, lien or encumbrance which is
senior in lien and position to this Mortgage and Security Agreement. Any
payments made or expenses incurred by Mortgagee in the exercise of such right
shall not release Mortgagor from Mortgagor's obligation or constitute a waiver
of Mortgagor's default hereunder. Any such payments made or expenses incurred by
Mortgagee shall be repayable within three (3) business days after demand by
Mortgagee, together with interest thereon at the rate specified in the Note from
the date such payment was made or

                                       13


<PAGE>



such expense was incurred, and the aggregate amount thereof, including such
interest, shall become part of the Aggregate Debt and shall be secured by the
lien of this Mortgage and Security Agreement.

         l4. Certificate of No Offsets. Within five (5) days after being
requested to do so by Mortgagee, Mortgagor shall furnish to Mortgagee or any
proposed assignee of this Mortgage and Security Agreement a statement, duly
executed, acknowledged and certified by Mortgagor, setting forth the remaining
unpaid amount of the Aggregate Debt and whether there exist any uncured
defaults, offsets or defenses thereto.

         l5. Right to Inspect. Mortgagor shall permit Mortgagee and its agents
to enter and inspect the Mortgaged Property or any part thereof at all
reasonable times during normal business hours and in such a manner so as not to
unreasonably interfere with Mortgagor's operations.

         l6. Revenue, Tax or Other Stamps. Mortgagor shall pay the cost of any
revenue, tax or other stamps now or hereafter required by the laws of the State
of New Jersey or the United States to be affixed to the Note or this Mortgage
and Security Agreement and if any taxes are imposed under the laws of the State
of New Jersey or the United States with respect to debts secured by a mortgage,
or with respect to evidences of indebtedness so secured, Mortgagor shall pay or
reimburse Mortgagee upon demand the amount of such taxes without credit against
any indebtedness evidenced by the Note. If Mortgagor does not or may not do so,
Mortgagee may at its option accelerate the indebtedness evidenced by the Note to
maturity as in the case of default by Mortgagor.

         17. Possession. Until an event of default shall have occurred under
this Mortgage and Security Agreement, Mortgagor shall be suffered and permitted
to retain actual possession of the Mortgaged Property, to manage, operate, use
and enjoy the same and all rights appertaining thereto, and to collect, receive,
take, use and enjoy the Income and Rents. The right of Mortgagor to collect the
Income and Rents may be revoked by Mortgagee at any time and from time to time
after an event of default has occurred under this Mortgage and Security
Agreement, by giving notice of such revocation to Mortgagor. Following the
giving of such notice, Mortgagee may retain and apply the Income and Rents
toward payment of the Aggregate Debt in such priority and proportions as
Mortgagee, in its discretion, shall determine.

         18. Events of Default.  The occurrence of any one or more
of the following events, after the expiration of any applicable

                                       14


<PAGE>



notice and/or cure period specifically provided for herein, shall, at the sole
option of the Mortgagee, constitute an "event of default" hereunder:

                  (a) Mortgagor shall fail to pay any regularly scheduled
installment of principal and/or interest due to Mortgagee under the Note when
the same shall become due and payable (including payment of the Loan on the
Maturity Date), or Mortgagor shall fail to make any other payment due under any
of the Loan Documents within fifteen (15) days after notice thereof from
Mortgagee;

                  (b) Except as otherwise provided for herein, Mortgagor shall
fail to observe or perform any of the covenants or agreements on its part to be
observed or performed under this Note or under any of the other Loan Documents
within thirty (30) days after written notice from Mortgagee of such
non-compliance, provided that if such non-compliance cannot reasonably be cured
within such thirty day period but Mortgagor undertakes within such thirty day
period and thereafter diligently pursues the curing of such non-compliance, then
the period within which Mortgagor shall cure such non-compliance shall be
extended to sixty (60) days after the original written notice from Mortgagee of
such non-compliance;

                  (c) Any representation or warranty of Mortgagor under this
Mortgage and Security Agreement or under any of the other Loan Documents shall
be untrue in any material respect;

                  (d) Any event of default, after the expiration of any
applicable notice and/or cure period specifically provided for therein, shall
occur under the terms of any of the other Loan Documents;

                  (e) Mortgagor shall apply for or consent to the appointment of
a receiver, trustee or liquidator of itself or any of its, admit in writing its
inability to pay its debts as they mature, make a general assignment for the
benefit of creditors, be adjudicated a bankrupt, insolvent or file a voluntary
petition in bankruptcy, or a petition or an answer seeking reorganization or an
arrangement with creditors or to take advantage of any bankruptcy,
reorganization, insolvency, readjustment of debt, dissolution or liquidation law
or statute, or an answer admitting the material allegations of a petition filed
against it in any proceeding under any such law, or if action shall be taken by
Mortgagor for the purpose of effecting any of the foregoing;

                  (f) Any order, judgment or decree shall be entered by
any court of competent jurisdiction, approving a petition seeking
reorganization of Mortgagor or all or a substantial part of the

                                       15


<PAGE>



assets of Mortgagor or appointing a receiver, sequestrator, trustee or
liquidator of Mortgagor or any of its property, and such order, judgment or
decree shall continue unstayed and in effect for any period of thirty (30) days.

         19. Remedies. Subject to the limitation set forth in paragraph 24
hereof, upon the occurrence of any event of default:

                  (a) The Aggregate Debt shall, at the option of Mortgagee,
become due and payable immediately without presentment, demand, notice of
nonpayment, protest, notice of protest or other notice of dishonor, all of which
are hereby expressly waived by Mortgagor.

                  (b) Mortgagee may institute appropriate proceedings at law or
equity to collect the amount of the Aggregate Debt then due (by acceleration or
otherwise), or for specific performance of any of the covenants of Mortgagor
under any of the Loan Documents (and Mortgagor acknowledges that all such
covenants may be specifically enforced by Mortgagee by injunction or other
appropriate equitable remedy), or to recover damages for any breach thereof, or
to institute an action of mortgage foreclosure against the Mortgaged Property,
or take such other action at law or in equity for the enforcement of this
Mortgage and Security Agreement and realization on the mortgage security or any
other security herein or elsewhere provided for, and proceed therein to final
judgment and execution for the Aggregate Debt, with interest as specified in
paragraph 21 below, together with costs and expenses as specified in paragraph
22 below.

                  (c) After demand upon Mortgagor for the surrender of
possession, Mortgagee may enter upon and take possession of the Mortgaged
Property, breaking locks if necessary and without liability for trespass,
damages or otherwise and, upon so doing, Mortgagee may, in its discretion and in
addition to any of its other rights, as Mortgagee in possession, alter, improve,
complete or repair the Mortgaged Property (and in so doing Mortgagee shall have
the right to use the Mortgaged Property and to expend such amount for that
purpose as Mortgagee shall deem best, all of which, with interest thereon at the
rate specified in the Note from date of payment, shall be repayable by Mortgagor
on demand and shall be secured hereby), and operate, rent, sell or lease the
same in the name of Mortgagor or Mortgagee upon such terms and conditions as
Mortgagee shall deem appropriate, and Mortgagor hereby irrevocably appoints
Mortgagee attorney-in-fact for Mortgagor for all such purposes while there
exists any uncured event of default hereunder.

                  (d) Mortgagee may further, by summary proceedings,
initiate an action for possession or otherwise, dispossess any

                                       16


<PAGE>



tenants, users or occupiers of the Mortgaged Property then or thereafter in
default in the payment of any rent or other charge for the use thereof, and any
tenants or other users or occupiers whose leasehold estates or rights to use the
Mortgaged Property are subordinate to the lien of this Mortgage and Security
Agreement, whether or not any such tenant, user or occupier is so in default;
and Mortgagor hereby irrevocably appoints Mortgagee attorney-in-fact of
Mortgagor for all such purposes. If Mortgagor remains in possession after demand
by Mortgagee for surrender of possession of the Mortgaged Property, such
continued possession by Mortgagor shall be as tenant of Mortgagee, and Mortgagor
agrees to pay monthly in advance to Mortgagee such rent for the Mortgaged
Property so occupied as Mortgagee may demand, and in default of so doing,
Mortgagor may also be dispossessed by summary proceedings or otherwise. In case
of the appointment of a receiver of the rents, the foregoing agreement of
Mortgagor to pay rent shall inure to the benefit of such receiver.

                  (e) With or without taking possession of the Mortgaged
Property, Mortgagee may collect and receive all the Income and Rents and, after
deducting the cost of all reasonable alterations, improvements, repairs,
completion, partial completion, operation, sale, rental, leasing commissions and
charges, including, but not limited to, counsel fees, incurred by Mortgagee,
apply the net income to the sums secured hereby in such manner as Mortgagee in
its discretion shall determine. Mortgagee shall be liable to account only for
the Income and Rents actually received.

                  (f) If Mortgagee shall so elect, Mortgagor shall not resist or
contest, but shall join in any petition to any court by Mortgagee for the
appointment of a receiver or receivers of the Mortgaged Property or any part
thereof, and of all the Income and Rents therefrom, with such powers as the
court making such appointment shall confer, and Mortgagor hereby appoints
Mortgagee attorney-in-fact of Mortgagor for all such purposes.

                  (g) All deposits held in connection with the rental, lease,
license or use of space or other facilities on the Mortgaged Property at the
time of the occurrence of such event of default, all interest of Mortgagor in
all premiums for, or dividends upon, any insurance for the Mortgaged Property,
and all refunds or rebates of taxes and assessments upon the Mortgaged Property,
are hereby assigned to Mortgagee as further security for the payment of the
Aggregate Debt during the continuance of any such event of default.

                  (h) To the extent now or hereafter permitted by law and
subject to such grace periods and notice requirements thereby imposed or imposed
by this Mortgage and Security Agreement,

                                       17


<PAGE>



Mortgagee may cause a judicial sale of the Mortgaged Property in accordance with
this subparagraph (h). Such sale may be made without demand on Mortgagor at the
time and place fixed in the notice of such sale, and such sale may be of the
Mortgaged Property as a whole or in separate lots, and in such order as
Mortgagee may determine, at public auction to the highest bidder for cash in
lawful money of the United States, payable at time of sale. Such sale of the
Mortgaged Property may be postponed by public announcement at the time and place
of sale, and may be further postponed from time to time thereafter by public
announcement at the time fixed by the preceding postponement. Any person or
entity, including Mortgagee, may purchase at such sale. After deducting all
costs, fees, and expenses of Mortgagee, including cost of evidence of title in
connection with such sale, the proceeds of sale shall be applied to payment of
the Aggregate Debt. The Mortgaged Property may be sold as aforesaid either
before, after, or during the pendency of any proceedings for the enforcement of
the provisions of this Mortgage and Security Agreement, and such power and right
of sale shall not be affected by any entry hereunder, or by the exercise of any
other right, remedy or power with respect to the enforcement of the provisions
of any of the Loan Documents or the collection of the amount of the Aggregate
Debt. The provisions of this subparagraph (h) are not intended to and shall not
adversely affect Mortgagee's rights to conduct a nonjudicial sale of such
portions of the Mortgaged Property as constitute personal property.

         20. Remedies Cumulative.

                  (a) No right or remedy conferred upon or reserved to Mortgagee
under any of the Loan Documents or with respect to any Collateral, or now or
hereafter existing at law or in equity or by statute or other legislative
enactment, is intended to be exclusive of any other such right or remedy and
each and every such right or remedy shall be cumulative and concurrent, and
shall be pursued separately, concurrently, successively or otherwise, at the
sole discretion of Mortgagee, and shall not be exhausted by any one exercise
thereof but may be exercised as often as occasion therefor shall occur. No act
of Mortgagee shall be deemed or construed as an election to proceed under any
one such right or remedy to the exclusion of any other such right or remedy;
furthermore, each such right or remedy of Mortgagee shall be separate, distinct
and cumulative and none shall be given effect to the exclusion of any other. The
failure to exercise or delay in exercising any such right or remedy, or the
failure to insist upon strict performance of any term of any of the Loan
Documents, shall not be construed as a waiver or release

                                       18


<PAGE>



of the same, or of any event of default thereunder, or of any obligation or
liability of Mortgagor thereunder.

                  (b) The recovery of any judgment by Mortgagee or the levy of
execution under any judgment upon the Mortgaged Property shall not affect in any
manner, or to any extent, the lien of this Mortgage and Security Agreement upon
the Mortgaged Property, or any security interest in any other Collateral, or any
rights, remedies or powers of Mortgagee under any of the Loan Documents or with
respect to any Collateral, but such lien and such security interest and such
rights, remedies and powers of Mortgagee shall continue unimpaired as before.
Further, the entry of any judgment by Mortgagee shall not affect in any way the
interest payable hereunder or under any of the other Loan Documents on any
amounts due to Mortgagee, but interest shall continue to accrue on such amounts
at the Default Rate (as hereinafter defined) after the entry of any judgment and
continuing until distribution of the proceeds of any Sheriff's sale.

                  (c) Mortgagor hereby waives presentment, demand, notice of
nonpayment, protest, notice of protest or other notice of dishonor, and except
to the extent specifically provided for herein, any and all other notices in
connection with any default in the payment of, or any enforcement of the payment
of, the Aggregate Debt except as provided in the Loan Documents. To the extent
permitted by law, Mortgagor waives the right to any stay of execution and the
benefit of all exemption laws now or hereinafter in effect.

                  (d) Mortgagor agrees that Mortgagee may release, compromise,
forbear with respect to, waive, suspend, extend or renew any of the terms of the
Loan Documents (and Mortgagor hereby waives any notice of any of the foregoing),
and that the Loan Documents may be amended, supplemented or modified by
Mortgagee and the other signatory parties and that Mortgagee may resort to any
Collateral in such order and manner as it may think fit, or accept the
assignment, substitution, exchange, pledge, or release of all or any portion of
any Collateral, for such consideration, or none, as it may require, without in
any way affecting the validity of any liens over or other security interest in
the remainder of any such Collateral (or the priority thereof or the position of
any subordinate holder of any lien or other security interest with respect
thereto); and any action taken by Mortgagee pursuant to the foregoing shall in
no way be construed as a waiver or release of any right or remedy of Mortgagee,
or of any event of default, or of any liability or obligation of Mortgagor,
under any of the Loan Documents.

                  (e) To the extent permitted by law, Mortgagor shall

                                       19


<PAGE>



not at any time insist upon, or plead, or in any manner whatever claim or take
any benefit or advantage of any stay or extension or moratorium law, or any
exemption from execution or sale of the Mortgaged Property, wherever enacted,
now or at any time hereafter in force, which may affect the covenants and terms
of performance of this Mortgage and Security Agreement, nor claim, take, or
insist upon any benefit or advantage of any law now or hereafter in force
providing for the valuation or appraisal of the Mortgaged Property, prior to any
sale of any of Mortgagor's interest therein; nor, after any such sale or sales,
claim or exercise any right under any statute heretofore or hereafter enacted to
redeem the Mortgaged Property so sold or any part thereof, and Mortgagor hereby
expressly waives all benefit or advantage of any such law or laws, and covenants
not to hinder, delay, or impede the execution of any power herein granted to
Mortgagee but to suffer and permit the execution of every power as though no
such law or laws had been made or enacted. Mortgagor further waives and releases
all procedural errors, defects and imperfections in any proceeding instituted by
Mortgagee under any of the Loan Documents.

                  (f) Mortgagor, for itself and for all persons hereafter
claiming through or under it or who may at any time hereinafter become holders
of liens junior to the lien of this Mortgage and Security Agreement, hereby
expressly waives and releases all rights to direct the order in which any of the
Mortgaged Property shall be sold in the event of any sale or sales pursuant
hereto and to have any of the Mortgaged Property and/or any other property now
or hereafter constituting security for the Aggregate Debt marshalled upon any
foreclosure of this Mortgage and Security Agreement or of any other security for
any of the Aggregate Debt.

                  (g) Mortgagor agrees that any action or proceeding against it
to enforce the Mortgage and Security Agreement may be commenced in state or
federal court in Camden County in the State of New Jersey and Mortgagor waives
personal service of process and agrees that a summons and complaint commencing
an action or proceeding in any such court shall be properly served if served by
registered or certified mail in accordance with the notice provisions set forth
herein and Mortgagor expressly waives any and all defenses to an exercise of
personal jurisdiction by any such court.

                  (h) Mortgagor hereby knowingly, voluntarily and
intentionally waives any right it may have to a trial by jury in
respect of any litigation based upon or arising out of, under or
in connection with this Mortgage, any of the other Loan Documents
or any course of conduct, course of dealing, statements (whether
verbal or written) or actions of Mortgagor or Mortgagee.  This

                                       20


<PAGE>



provision is a material inducement for Mortgagee to make the Loan.

         21. Default Rate. Following the occurrence of any event of default and
continuing either until such event of default is cured and that fact
acknowledged by Mortgagee or until the principal sum then outstanding under the
Note and all other sums payable under the Loan Documents are paid in full, the
principal sum outstanding under the Note shall bear interest at rate equal to
the annual interest rate then applicable under paragraph 1 of the Note plus four
percent (4%) per annum, which rate shall change if, when and as such interest
rate changes ("Default Rate"), and shall be secured by the Mortgage and all
other Collateral.

         22. Costs and Expenses. Following the occurrence of any event of
default under any of the Loan Documents, Mortgagor shall pay upon demand all
reasonable costs and expenses (including all amounts paid to attorneys,
accountants, real estate brokers and other advisors employed by Mortgagee and to
any contractors for labor and materials), incurred by Mortgagee in the exercise
of any of its rights, remedies or powers under any of the Loan Documents or with
respect to any Collateral with respect to such event of default, and any amount
thereof not paid promptly following demand therefor, together with interest
thereon at the Default Rate from the date of such demand, shall become part of
the Aggregate Debt and shall be secured by the lien of this Mortgage and
Security Agreement. In connection with and as part of the foregoing, in the
event that any of the Loan Documents is placed in the hands of any attorney for
the collection of any sum payable thereunder, Mortgagor agrees to pay attorneys'
fees for the collection of the amount being claimed under such Loan Documents,
as well as all costs, disbursements and allowances provided by law, and the
payment of such fees and costs, disbursements and allowances shall also be
secured by the lien of this Mortgage and Security Agreement. Nothing in this
paragraph 22 shall limit the obligation of Mortgagor to pay costs and expenses
of Mortgagee for which Mortgagor is otherwise liable under the Loan Documents.

         23. Renewals and Extensions. This Mortgage and Security Agreement shall
secure any and all renewals, or extensions of the whole or any part of the
indebtedness hereby secured however evidenced, with interest at such lawful rate
as may be agreed upon and any such renewals or extensions or any change in the
terms or rate of interest shall not impair in any manner the validity of or
priority of this Mortgage and Security Agreement, nor release Mortgagor from
personal liability for the indebtedness hereby secured.

                                       21


<PAGE>



         24. Limited Liability of Mortgagor. Except as hereinafter set forth,
Mortgagor shall not have any personal liability for the payment of the Loan or
for the payment of any sum or performance of any obligation under any of the
Loan Documents, and in the event of a default under this Mortgage and Security
Agreement or any of the other Loan Documents, Mortgagee will look solely to the
Real Property and Improvements, the rents, issues and profits thereof and any
other Collateral specifically pledged, assigned or granted by Mortgagor to
Mortgagee as security for the Loan pursuant to this Mortgage and Security
Agreement or any of the other Loan Documents, and any judgment obtained against
Mortgagor shall so note by its terms or as otherwise permissible by law. Subject
to the aforesaid limitation, nothing herein contained shall be construed to
prevent Mortgagee from exercising and enforcing any other remedy against
Mortgagor or any other person or entity allowed at law or in equity or by any
statute or by the terms of this Mortgage and Security Agreement or any of the
other Loan Documents or any other deed of trust, mortgage, security agreement,
assignment of leases and rents, guaranty or any other security instrument of any
kind now or hereafter securing payment of the Loan. In addition, notwithstanding
anything to the contrary contained herein, Mortgagor shall indemnify and hold
Mortgagee harmless against, and shall be personally liable and obligated to
Mortgagee for:

                  (a) the completion of construction of the Tenant Improvements
in accordance with the respective deadlines therefor in the New Leases free and
clear of any and all mechanics liens and any other liens and encumbrances;

                  (b) the payment on a current basis of all monthly installments
of principal and interest with respect to the Acquisition Portion of the Loan
and interest with respect to the Tenant Improvement Portion of the Loan (but
excluding therefrom the entire unpaid principal balance of the Loan becoming due
as a result of maturity or acceleration of the Loan to the extent not
constituting a regular monthly installment);

                  (c) the principal amount of the Loan to the extent of
$3,000,000, which may be allocated between the Acquisition Portion of the Loan
and Tenant Improvement Portion of the Loan as Mortgagee shall determine in its
sole discretion, and which shall not be reduced by any payments on account of
the Acquisition Portion of the Loan or Tenant Improvement Portion of the Loan by
Mortgagor or by any other person or entity, whether by payments in the ordinary
course or by mortgage foreclosure or otherwise; and

                  (d) an amount equal to all loss, liability, damage,

                                       22


<PAGE>



cost and expense suffered or incurred by Mortgagee in any way arising out of,
resulting from or relating to any one or more of the following: (i) any fraud or
willful material misrepresentation committed by Mortgagor; (ii) any retention by
Mortgagor of rental income, security deposits, or similar income of the Real
Property and Improvements after an event of default has occurred under the Loan
Documents to the extent of any such retention; (iii) any real property taxes or
assessments accrued prior to Mortgagee's acquisition of ownership of the Real
Property and Improvements following a default by Mortgagor under the Loan; (iv)
removal or failure to replace any personal property securing the Loan, other
than in the ordinary course of Mortgagor's business; (v) misapplication of
insurance or condemnation proceeds relating to the Real Property and
Improvements; (vi) failure to maintain hazard or liability insurance relating to
the Real Property and Improvements, in accordance with the Loan Documents; (vii)
the presence of any Hazardous Substances or Wastes which may affect the Real
Property and Improvements, or any misrepresentation or breach of any covenants
or indemnities by Mortgagor set forth in the Loan Documents with respect to
Hazardous Substances or Wastes; (viii) any transfer of the Real Property and
Improvements or any portion thereof other than Permitted Transfers; (ix) any
indebtedness secured by a mortgage covering the Real Property and Improvements
other than the Seller Loan; (x) any bankruptcy, reorganization, insolvency,
readjustment of debt, dissolution, liquidation or receivership proceedings
instituted by or against Mortgagor, unless and except to the extent that such
proceedings are withdrawn, dismissed or discharged within ninety (90) days or
unless Mortgagee obtains title to the Real Property and Improvements within nine
(9) months; and (xi) all fees and costs, including reasonable attorney fees,
incurred in enforcing and collecting the foregoing.

         25. Severability. In the event that for any reason one or more of the
provisions of this Mortgage and Security Agreement or their application to any
person or circumstance shall be held to be invalid, illegal, or unenforceable in
any respect or to any extent, such provisions shall nevertheless remain valid,
legal and enforceable in all such other respects and to such extent as may be
permissible. In addition, any such invalidity, illegality, or unenforceability
shall not affect any other provision of this Mortgage and Security Agreement,
but this Mortgage and Security Agreement shall be construed as if such invalid,
illegal or unenforceable provision had never been contained herein.

         26. Successors and Assigns.  This Mortgage and Security
Agreement inures to the benefit of Mortgagee and binds Mortgagor,
and their respective successors and assigns and the words
