collect the Rents.  Mortgagor shall hold the Rents, or an amount sufficient
to discharge all sums then currently due on the Debt, in trust for use in
payment of the Debt.  The right of Mortgagor to collect the Rents may be

with the provisions of the Credit Agreement, or to the operation,
maintenance and repair of the Mortgaged Property, and irrespective of
whether Mortgagee shall have commenced a foreclosure of this Mortgage or
shall have applied or arranged for the appointment of a receiver.

not be unreasonably withheld, conditioned or delayed, make, or suffer to be
made, any Other Leases or modify or cancel any Other Leases or accept

its interest in any of the Other Leases, or further assign the Rents so
long as any part of the Debt remains unpaid.

no part of the Mortgaged Property and no legal or beneficial interest in
Mortgagor shall in any manner be further encumbered, sold, transferred,
assigned or conveyed, or permitted to be further encumbered, sold,
transferred, assigned or conveyed without the consent of Mortgagee.  The
provisions of this paragraph shall apply to each and every such further
encumbrance, sale, transfer, assignment or conveyance, regardless of
whether or not Mortgagee has consented to, or waived by its action or
inaction its rights hereunder with respect to any such previous further
encumbrance, sale, transfer, assignment or conveyance and irrespective of
whether such further encumbrance, sale, transfer, assignment or conveyance
is voluntary, by reason of operation of law or is otherwise made.

          10.  Notice.  All notices, consents, directions, approvals,
authorizations, instructions, demands, statements, requests and other
communications given or made hereunder or in connection herewith shall be
sent in accordance with the provisions of and to the addresses set forth in
Section 8.1 of the Credit Agreement.

          11.  Changes in Laws Regarding Taxation.  In the event of the
passage after the date of this mortgage of any law of the State of New
Jersey deducting from the value of real property for the purpose of
taxation any lien or encumbrance thereon or changing in any way the laws
for the taxation of mortgages or deeds of trust or debts secured by
mortgages or deeds of trust for state or local purposes or the manner of
the collection of any such taxes, and imposing a tax, either directly or
indirectly, on this Mortgage, the Notes, the Credit Agreement, any of the
Loan Instruments or the Debt, Mortgagor shall, if permitted by law, pay any
tax imposed as a result of any such law within the statutory period or
within thirty (30) days after demand by Mortgagee, whichever is less,
provided, however, that if, in the opinion of the attorneys for Mortgagee,
Mortgagor is not permitted by law to pay such taxes, Mortgagee shall have
the right, at its option, to declare the Debt due and payable on

                                    11

<PAGE>

a date specified in a prior notice to Mortgagor of not less than sixty (60)
days.

          12.  [Intentionally Omitted]

          13.  Sale of Mortgaged Property.  If this Mortgage is foreclosed,
the Mortgaged Property, or any interest therein, may, at the discretion of
Mortgagee, be sold in one or more parcels or in several interests or
portions and in any order or manner.

          14.  No Credits on Account of the Debt.  Mortgagor will not claim
or demand or be entitled to any credit or credits on account of the Debt
for any part of the Taxes assessed against the Mortgaged Property or any
part thereof and no deduction shall otherwise be made or claimed from the
taxable value of the Mortgaged Property, or any part thereof, by reason of
this Mortgage or the Debt.

          15.  Other Security for the Debt.  Mortgagor shall observe and
perform all of the terms, covenants and provisions on the part of Mortgagor
to be observed and performed contained in the Credit Agreement and the Loan
'Instruments and in all other mortgages and other instruments or documents
evidencing, securing or guaranteeing payment of the Debt, in whole or in
part, or otherwise executed and delivered in connection with the Credit
Agreement, the Notes or this Mortgage.

          16.  Documentary Stamps.  If at any time the United States of
America, any state thereof or any governmental subdivision of any such
state, shall require revenue or other stamps to be affixed to the Notes or
this Mortgage, Mortgagor will pay the same, with interest and penalties
thereon, if any.

          17.  Right of Entry.  Mortgagee and its agents shall have the
right to enter and inspect the Mortgaged Property as provided in the Credit
Agreement.

          18.  Books and Records.  Mortgagor will comply with all of the

                                    12

          19.  Ground Lease.

          (a)   Mortgagor  shall  (i) pay all rents, additional  rents  and
other  sums  required to be paid by the tenant under and  pursuant  to  the
provisions of the Ground Lease, (ii) diligently perform and observe all  of
the  terms, covenants and conditions of the Ground Lease on the part of the
tenant thereunder to be performed and observed, unless such performance  or
observance shall be waived or not required by the landlord under the Ground
Lease, to the end that all things shall be done which are necessary to keep
unimpaired  the  rights  of the tenant under the Ground  Lease,  and  (iii)
promptly notify Mortgagee of the giving of any notice by the landlord under
the Ground Lease of any default in the performance or observance of any  of
the  terms, covenants or conditions of the Ground Lease on the part of  the
tenant  thereunder to be performed or observed and deliver to  Mortgagee  a
true  copy  of  each such notice.  Mortgagor shall not, without  the  prior
consent  of  Mortgagee,  which consent shall not be unreasonably  withheld,
conditioned  or  delayed, surrender the leasehold  estate  created  by  the
Ground  Lease  or  terminate or cancel the Ground Lease or modify,  change,
supplement, alter or amend the Ground Lease, in any respect, either  orally
or  in  writing,  and  Mortgagor hereby assigns to  Mortgagee,  as  further
security for the payment of the Debt and for the performance and observance
of  the  terms,  covenants  and conditions of  this  Mortgage,  the  Credit
Agreement and the other Loan Instruments, all of the rights, privileges and
prerogatives  of  the  tenant  under the  Ground  Lease  to  surrender  any
leasehold  estate or easement interests created by the Ground Lease  or  to
terminate,  cancel, modify, change, supplement, alter or amend  the  Ground
Lease, and any such surrender of the leasehold estate or easement interests
created  by  the  Ground Lease or termination, cancellation,  modification,
change, supplement, alteration or amendment of the Ground Lease without the
prior  consent of Mortgagee, shall be void and of no force and effect.   If
Mortgagor  shall  default  in the performance or observance  of  any  term,
covenant  or  condition of the Ground Lease to be performed or observed  by
the  tenant thereunder, then, without limiting the generality of the  other
provisions  of  this  Mortgage, and without waiving or releasing  Mortgagor
from any of its obligations hereunder, Mortgagee shall have the right,  but
shall  be  under no obligation, to pay any sums and to perform any  act  or
take  any action as may be appropriate to cause all of the terms, covenants
and conditions of the Ground

                                    13

<PAGE>

Lease on the part of the tenant thereunder to be performed or observed, to
be promptly performed or observed on behalf of Mortgagor, to the end that
the rights of Mortgagor in, to and under the Ground Lease shall be kept
unimpaired and free from default.  If Mortgagee shall make any payment or
perform any act or take action in accordance with the preceding sentence,
Mortgagee will notify Mortgagor of the making of any such payment, the
performance of any such act, or taking of any such action.  In any such
event, subject to the rights of lessees, and other occupants under the
Other Leases, Mortgagee and any person designated by Mortgagee shall have,
and are hereby granted, the right to enter upon the Mortgaged Property at
any time and from time to time for the purpose of taking any such action.
If the landlord under the Ground Lease shall deliver to Mortgagee a copy of
any notice of default sent by said landlord to Mortgagor, as tenant under
such Ground Lease, such notice shall constitute full protection to
Mortgagee for any action taken or omitted to be taken by Mortgagee, in good
faith, in reliance thereon.  Mortgagor shall, from time to time, use its
reasonable efforts to obtain from the landlord under the Ground Lease such
certificates of estoppel with respect to compliance by Mortgagor with the
terms of the Ground Lease as may be reasonably requested by Mortgagee.
Mortgagor shall exercise each individual option, if any, to extend or renew
the term of the Ground Lease, or option to purchase or right of first
refusal with respect to purchase of the Leasehold Premises, as the case may
be, upon demand by Mortgagee made at any time within one (1) year of the
last day upon which any such option may be exercised, and Mortgagor hereby
expressly authorizes and appoints Mortgagee its attorney-in-fact to
exercise, either jointly or individually, any such option or right of first
refusal in the name of and upon behalf of Mortgagor, which power of
attorney shall be irrevocable and shall be deemed to be coupled with an
interest.

          (b)  Mortgagor shall not, without Mortgagee's prior written
consent, elect to treat either the Ground Lease or the leasehold estate
created thereby as terminated under Subsection 365(h)(1) of the Bankruptcy
Code, after rejection or disaffirmance of the Ground Lease by the landlord
thereunder or by any trustee of such party, and any such election made
without such consent shall be void and ineffective.

                                    14

<PAGE>

          (c)  Subject to the Mortgagor's right to seek and retain certain
offsets as permitted hereunder, Mortgagor hereby unconditionally assigns,
transfers and sets over to Mortgagee all of Mortgagor's claims and rights
to the payment of damages that may hereafter arise as a result of any
rejection or disaffirmance of the Ground Lease by the landlord thereunder
or by any trustee of such party, pursuant to the Bankruptcy Code.
Mortgagee shall have and is hereby granted the right to proceed, in its own
name or in the name of the Mortgagor, in respect of any claim, suit, action
or proceeding relating to the rejection or disaffirmance of the Ground
Lease (including, without limitation, the right to file and prosecute, to
the exclusion of Mortgagor, any proofs of claim, complaints, motions,
applications, notices and other documents) in any case in respect of the
landlord under the Bankruptcy Code.  This assignment constitutes a present,
irrevocable and unconditional assignment of the foregoing claims, rights
and remedies, and shall continue in effect until the Debt secured by this
Mortgage shall have been satisfied and discharged in full.  Any amounts
received by Mortgagee as damages arising out of any such rejection of the
Ground Lease shall be applied toward payment of the Debt in such order and
priority as contemplated under the Credit Agreement.

          (d)  In the event that, pursuant to Subsection 365(h)(2) of the
Bankruptcy Code, Mortgagor seeks to offset against the rent payable under
the Ground Lease the amount of any damages caused by the nonperformance by
the landlord of such party's obligations under the Ground Lease after
rejection or disaffirmance thereof under the Bankruptcy Code, Mortgagor
shall, prior to effecting such offset, notify Mortgagee in writing of
Mortgagor's intent to do so, setting forth the amounts proposed to be so
offset and the basis therefor.  Mortgagee shall have the right to object in
writing (stating the reasons therefor) to all Dr any part of such offset,
and, in the event of such objection, Mortgagor shall not effect any offset
of the amounts so objected to by Mortgagee.  If Mortgagee shall have failed
to object as aforesaid within twenty (20) days after such notice, Mortgagor
may proceed to effect such offset in the amounts set forth in such notice.
Neither Mortgagee's failure to object as aforesaid nor any objection or
other communication between Mortgagor and Mortgagee relating to such offset
shall constitute an approval by Mortgagee of any such offset.  If, in the
best business judgment of the Mortgagor,

                                    15

<PAGE>

such offset is justified and Mortgagee has received the aforesaid notices
and has not objected but its time to do so has not expired, the Mortgagor
shall have the right to make such offset and shall set aside the offset
amount as a reserve to be paid only if Mortgagee objects within the
aforesaid time.  Mortgagor shall indemnify and hold Mortgagee and its
officers, directors, employees and agents harmless from and against any and
all claims, demands, actions, suits, proceedings, damages, losses, costs
and expenses of every nature whatsoever actually incurred (including,
without limitation, reasonable legal fees and disbursements) arising from
or relating to any such offset by Mortgagor.

          (e)  Mortgagor shall, promptly after obtaining knowledge thereof,
use its best efforts to give prompt oral notice to Mortgagee of any actual
or contemplated filing by or against the landlord under the Ground Lease of
a petition under the Bankruptcy Code, and give prompt written notice
thereof to Mortgagee of such actual or contemplated filing.  The aforesaid
written notice shall set forth any information available to Mortgagor
concerning the date or anticipated date of such filing, the court in which
such petition was filed or is expected to be filed, and the relief sought
or reasonably expected to be sought therein.  Mortgagor shall, promptly
after receipt thereof, deliver to Mortgagee any and all notices, summonses,
pleadings, applications and other documents received by Mortgagor in
connection with any such petition and any proceedings related thereto.

          (f)  In the event that any action, proceeding, motion or notice
shall be commenced or. filed in respect of the landlord under the Ground
Lease or the Mortgaged Property or any part thereof, in connection with any
case under the Bankruptcy Code, Mortgagee shall have, and is hereby
granted, the option, to the exclusion of Mortgagor, exercisable upon notice
from Mortgagee to Mortgagor, to conduct and control any such litigation
with counsel of Mortgagee's choice.  Mortgagee may proceed, in its own name
or in the name of Mortgagor, in connection with any such litigation, and
Mortgagor agrees to execute any and all powers, authorizations, consents
and other documents required by Mortgagee in connection therewith.
Mortgagor shall, upon demand, pay to Mortgagee all costs and expenses
(including without limitation, legal fees and disbursements) paid or
incurred by Mortgagee in connection with the prosecution or conduct of any
such proceedings, and, to the

                                    16

<PAGE>

extent permitted by law, such costs and expenses shall be deemed expenses
incurred in upholding the lien of this Mortgage and added to the
indebtedness secured by this Mortgage.  Mortgagor shall not, without the
prior written consent of Mortgagee, commence any action, suit, proceeding
or case, or file any application or make any motion, in respect of the
Ground Lease in any such case under the Bankruptcy Code.

          (g)  In the event that a petition under the Bankruptcy Code shall
be filed by or against Mortgagor, and Mortgagor, or anyone claiming through
or under Mortgagor or a trustee in bankruptcy shall have the right to
reject the Ground Lease pursuant to Section 365(a) of the Bankruptcy Code
or a successor statute, Mortgagor shall give Mortgagee at least ten (10)
days' prior written notice of the date on which application shall be made
to the court for authority to reject the Ground Lease; provided, however,
that if a trustee in bankruptcy shall have a right to reject the Ground
Lease in less than ten (10) days, then Mortgagor shall give such notice to
Mortgagee immediately upon Mortgagor's knowledge of such application.
Mortgagee shall have the exclusive right, but not the obligation (subject
to ,the rights of a trustee in bankruptcy), to exercise said right and
Mortgagor hereby assigns said right to Mortgagee.  If at any time the
landlord under the Ground Lease, or anyone holding by, through or under the
landlord under the Ground Lease or a trustee in bankruptcy shall elect to
reject the Ground Lease pursuant to Section 365(a) of the Bankruptcy Code,
or a successor statute, thereby giving to Mortgagor the right to elect to
treat the Ground Lease as terminated pursuant to Section 365kri)(l) of the
Bankruptcy Code, or a successor statute, Mortgagee shall have the exclusive
right to exercise said right and Mortgagor hereby assigns said right to
Mortgagee.  If either of the assignments provided for in this paragraph is
held to be enforceable, then Mortgagor, anyone claiming by, through or
under Mortgagor or a trustee in bankruptcy, shall not exercise rights
purportedly assigned to Mortgagee without the prior written consent of
Mortgagee, and if Mortgagee shall give such consent, Mortgagor, anyone
claiming by, through or under Mortgagor or a trustee in bankruptcy shall
promptly exercise either of said rights.

          (h)  To the extent permitted by applicable law, Mortgagor hereby
assigns, transfers and sets over to Mortgagee an exclusive right to apply
to the Bankruptcy

                                    17

<PAGE>

Court under Subsection 365(d)(4) of the Bankruptcy Code for an order
extending the period during which the Ground Lease may be rejected or
assumed after the entry of any order for relief in respect of Mortgagor
under Chapter 7 or Chapter 11 of the Bankruptcy Code.

          20.  No Merger of Fee and Leasehold Estates.  So long as any
portion of the Debt shall remain unpaid, unless Mortgagee shall otherwise
consent, then the fee title to the Leasehold Premises and the leasehold
estate therein created pursuant to the provisions of the Ground Lease and
the fee title to the Improvements and all Equipment constituting a fixture,
and the fee title to the Easement Premises and the interests in real
property arising under the provisions of the Easements, shall not merge but
shall always be kept separate and distinct, notwithstanding the union of
such estates in Mortgagor, or in any other person (including Mortgagee) by
purchase, operation of law or otherwise (including without limitation a
union of estates arising from a foreclosure sale purchase or deed in lieu
of foreclosure).

          21.  Performance of Other Agreements.  Mortgagor shall observe
and perform each and every term to be observed or performed by Mortgagor
pursuant to the terms of any agreement or recorded instrument affecting or
pertaining to the Mortgaged Property.

          22.  Defaults.  The Debt shall become due at the option of
Mortgagee upon the occurrence of any one of the following events:

          (a)  if any Event of Default under the Credit Agreement shall
occur;

          (b)  if Mortgagor shall be in default beyond the expiration of
any applicable notice and cure period under any mortgage or deed of trust
covering any part of the Mortgaged Property whether superior or inferior in
lien to this Mortgage.

          23.  Right to Cure Defaults.  If default in the performance of
any of the covenants of Mortgagor herein occurs, Mortgagee, without waiving
any default or releasing Mortgagor from any obligation, may (but shall be
under no obligation to) remedy the same for the account and at the cost and
expense of Mortgagor, and for such purpose shall

                                    18

<PAGE>

have the right to enter upon the Mortgaged Property without thereby
becoming liable to Mortgagor or any person in possession thereof holding
under Mortgagor.  If Mortgagee shall remedy such a Default or appear in,
defend or bring any action or proceeding to protect its interest in the
Mortgaged Property or to foreclose this Mortgage or collect the Debt, all
costs and expenses actually incurred (including, without limitation,
reasonable attorneys' fees) shall be paid by Mortgagor to Mortgagee on
demand with interest to the date of payment to Mortgagee at the Default
Interest Rate.  All such costs and expenses incurred by Mortgagee, with
interest at the Default Interest Rate. shall be secured by this Mortgage.

          24.  Appointment of Receiver.  Mortgagee, in any action to
foreclose this Mortgage or upon the actual or threatened waste to any part
of the Mortgaged Property or upon the occurrence of any default hereunder,
shall be at liberty, without notice, to apply for the appointment of a
receiver of the Rents, and shall be entitled to the appointment of such
receiver as a matter of right, without regard to the value of the Mortgaged
Property as security for the Debt, or the solvency or insolvency of any
person then liable for the payment of the Debt.

          25.  Remedies Upon an Event of Default.  Upon the occurrence of
any event described in paragraph 22 of this Mortgage, then Mortgagee may,
to the extent permitted by law, exercise any right, power or remedy
permitted to it hereunder, under the Credit Agreement or under any other
Loan Instruments, and, without limiting the generality of the foregoing,
Mortgagee may, personally or by its agents, do any or all of the following:

          (a)  declare the Debt to be immediately due and payable, and if
the same is not paid on demand, at Mortgagee's option, bring suit for any
delinquent payments under the Notes and take any and all steps and any and
all other proceedings that Mortgagee deems necessary to enforce the
indebtedness and obligations secured hereby and to protect the lien of this
Mortgage; and

          (b)  enter and take possession of the Mortgaged Property or any
part thereof, exclude the Mortgagor and all persons claiming under the
Mortgagor whose claims are junior to this Mortgage, wholly or partly

                                    19

<PAGE>

therefrom, and use, operate, manage and control the same either in the name
of the Mortgagor or otherwise as Mortgagee shall deem best, and upon such
entry, from time to time at the expense of the Mortgagor and the Mortgaged
Property, make all such repairs, replacements, alterations, additions or
improvements to the Mortgaged Property or any part thereof as Mortgagee may
deem proper and, whether or not Mortgagee has so entered and taken
possession of the Mortgaged Property or any part thereof, collect and
receive all the Rents and apply the same, to the extent permitted by law,
to the payment of all expenses which Mortgagee may be authorized to incur
under this Mortgage, the remainder to be applied to the payment of the Debt
until the same shall have been repaid in full; if Mortgagee demands or
attempts to take possession of the Mortgaged Property or any portion
thereof in the exercise of any rights hereunder, Mortgagor shall promptly
turn over and deliver complete possession thereto to Mortgagee; and

          (c)  proceed to protect and enforce its rights under this
Mortgage by suit for specific performance of any covenant contained herein,
in the Credit Agreement or in the Loan Instruments or in aid of the
execution of any power granted herein, in the Credit Agreement or in the
Loan Instruments, or for the foreclosure of this Mortgage and the sale of
the Mortgaged Property under the judgment or decree of a court of competent
jurisdiction, or for the enforcement of any other right as Mortgagee shall
deem effectual for such purpose; provided that in the event of a sale, by
foreclosure or otherwise, of less than ail of the Mortgaged Property, this
Mortgage shall continue as a lien on, and security interest in, the
remaining portion of the Mortgaged Property; and

          (d)  exercise any or all of the remedies available to a secured
party under the Uniform Commercial Code as provided in paragraph 35 hereof;
and

          (e)  without in any way limiting the rights hereunder pursuant to
paragraphs 6, 24 and 35 apply for the appointment of a receiver as a matter
of right, without regard to the adequacy of the security for the Debt or
the solvency of the Mortgagor.  Mortgagor hereby irrevocably consents to
such appointment.  Specifically, the Mortgagee or any receiver shall be

                                    20

<PAGE>

entitled to take possession of the Mortgaged Property from the owners,
tenants and/or occupants of the whole or any part thereof and to collect
and receive the Rents and the value of the use and occupation of the
Mortgaged Property, or any part thereof, from the then owner, tenants
and/or occupants thereof for the benefit of Mortgagee.

          26.  Mortgagor as Tenant Holding over.  In the event of any
foreclosure sale contemplated under paragraph 25 hereof, Mortgagor shall be
deemed to be a tenant holding over and shall forthwith deliver possession
to the purchaser or purchasers at such sale or be summarily dispossessed
according to provisions of law applicable to tenants holding over.

          27.  Discontinuance of Proceedings.  In case Mortgagee shall have
proceeded to enforce any right, power or remedy under this Mortgage by
foreclosure, entry or otherwise, and such proceeding shall have been
withdrawn, discontinued or abandoned for any reason, or shall have been
determined adverse to Mortgagee, then in every such case (a) Mortgagor and
Mortgagee shall be restored to their former positions and rights, (b) all
rights, powers and remedies of Mortgagee shall continue as if no such
proceeding had been taken, (c) each and every uncured default declared or
occurring prior or subsequent to such withdrawal, discontinuance or
abandonment shall be or shall be deemed to be a continuing default and (d)
neither the Debt, this Mortgage, the Notes, the Credit Agreement nor the
other Loan Instruments, shall be or shall be deemed to have been affected
by such withdrawal, discontinuance or abandonment; and Mortgagor hereby
expressly waives the benefit of any statute or rule of law now provided, or
which may hereafter conflict with the above.

          28.  No Reinstatement.  If a default shall have occurred and
Mortgagee shall have proceeded to enforce any right, power or remedy
permitted hereunder, then a tender of payment by Mortgagor or by anyone on
behalf of Mortgagor of any amount less than the amount necessary to satisfy
the Debt in full, or the acceptance by Mortgagee of any such payment so
tendered, shall not constitute a reinstatement of this Mortgage, the Notes,
the Credit Agreement or any Loan Instrument.

                                    21

<PAGE>

          29.  Mortgagor's Waiver of Rights.  To the full extent permitted
by law, except as otherwise specifically and expressly provided in this
Mortgage, the Credit Agreement or any Loan Instrument, Mortgagor waives the
benefit of all laws now existing or that hereafter may be enacted providing
for (i) any appraisement before sale of any portion of the Mortgaged
Property and (ii) the benefit of all Laws that may be hereafter enacted in
any way extending the time for the enforcement of the collection of the
Debt, or creating or extending a period of redemption from any sale made in
collecting said Debt.  To the full extent that Mortgagor may do so,
Mortgagor agrees that Mortgagor will not at any time insist upon, plead,
claim or take the benefit or advantage of any law now or hereafter in force
providing for any appraisement, valuation, stay, extension or redemption,
or any so-called "Moratorium Laws" and Mortgagor, for Mortgagor and its
successors and assigns, and for any and all persons ever claiming any
interest in the Mortgaged Property, hereby waives and releases all rights
of redemption, valuation, appraisement, stay of execution, notice of
election to mature or declare due the whole of the secured indebtedness and
marshaling in the event of foreclosure of the liens hereby created.  If any
 .Law referred to in this paragraph and now in force, of which Mortgagor,
Mortgagor's successors and assigns or any other person might take advantage
despite this paragraph, shall hereafter be repealed or cease to be in
force, such Law shall not thereafter be deemed to preclude the application
of this paragraph.

          30.  Non-Waiver.  The failure of Mortgagee to insist upon strict
performance of any term of this Mortgage shall not be deemed to be a waiver
of any term of this Mortgage.  Borrowers shall not be relieved of their
obligation to pay the Debt at the time and in the manner provided for its
payment in the Notes, the Credit Agreement and the Loan Instruments (nor
shall any of Mortgagor's other obligations hereunder, under the Credit
Agreement or the other Loan Instruments, nor shall the other Borrowers'
obligations under the Credit Agreement or the other Loan Instruments be in
any way affected) by reason of (i) failure of Mortgagee to comply with any
request of Mortgagor or the other Borrowers to take any action to foreclose
this Mortgage or otherwise enforce any of the provisions hereof or of the
Notes, the Credit Agreement, any other Loan Instruments or any other
mortgage, instrument or document evidencing, securing or guaranteeing
payment of the Debt or

                                    22

<PAGE>

any portion thereof, (ii) the release, regardless of consideration, of the
whole or any part of the Mortgaged Property or any other security for the
Debt, or (iii) any agreement or stipulation between mortgagee and any
subsequent owner or owners of the Mortgaged Property or other person
extending the time of payment or otherwise modifying or supplementing the
terms of the Notes, the Credit Agreement, the Loan Instruments, this
Mortgage or any other mortgage, instrument or document evidencing, securing
or guaranteeing payment of the Debt or any portion thereof, without first
having obtained the consent of Mortgagor, and in the latter event,
Mortgagor shall continue to be obligated to pay the Debt at the time and in
the manner provided in the Notes, the Credit Agreement, the Loan
Instruments, and this Mortgage (as so extended, modified or supplemented,
if such be the case) and shall continue to be obligated to perform its
other obligations hereunder and under the Credit Agreement and the Loan
Instruments (in each case, as so extended, modified and supplemented)
unless expressly released and discharged from such obligation by Mortgagee
in writing.  Regardless of consideration, and without the necessity for any
notice to or consent by the holder of any subordinate lien, encumbrance,
right, title or interest in or to the Mortgaged Property, Mortgagee may
release any person at any time liable for the payment of the Debt or any
portion thereof or any part of the security held for the Debt and may
extend the time of payment or otherwise modify the terms of the Notes, the
Credit Agreement, the Loan Instruments or this Mortgage (including, without
limitation, a modification of the interest rate payable on the principal
balance of the Notes) without in any manner impairing or affecting this
Mortgage or the lien thereof or the priority of this Mortgage, as so
extended and modified, as security for the Debt over any such subordinate
lien, encumbrance, right, title or interest.

          31.  Remedies Cumulative.  Mortgagee may resort for the payment
of the Debt to any other security held by Mortgagee in such order and
manner as Mortgagee, in its discretion, may elect.  Mortgagee may take
action to recover the Debt, or any portion thereof, or to enforce any
covenant hereof without prejudice to the rights of Mortgagee thereafter to
foreclose this Mortgage.  Mortgagee shall not be limited exclusively to the
rights and remedies herein stated but shall be entitled to every additional
right and remedy now or hereafter afforded by Law or equity.  The rights of
mortgagee under this Mortgage shall be separate,

                                    23

<PAGE>

distinct and cumulative and none shall be given effect to the exclusion of
the others.  No act of Mortgagee shall be construed as an election to
proceed under any one provision herein to the exclusion of any other
provision.  Mortgagee shall be entitled to enforce payment of the Debt and
performance of any of the obligations of the Mortgagor and to exercise all
rights and powers under this Mortgage or under any other Loan Instrument or
any Laws now or hereafter in force, notwithstanding that some or all of
such obligations may now or hereafter be otherwise secured, whether by
mortgage, pledge, lien, assignment or otherwise; neither the acceptance of
this Mortgage nor its enforcement, whether by court action or pursuant to
other powers herein contained, shall prejudice or in any manner affect
Mortgagee's right to realize upon or enforce any other security now or
hereafter held by the Mortgagor, it being stipulated that Mortgagee shall
be entitled to enforce this Mortgage and any other security now or
hereafter held by Mortgagee in such order and manner as Mortgagee, in
accordance with the terms hereof, may determine; every power or remedy
given by the Credit Agreement, this Mortgage or any of the other Loan
Instruments to the Mortgagee or to which the Mortgagee is otherwise
entitled, may be exercised, concurrently or independently, from time to
time and as often as may be deemed expedient by Mortgagee.

          32.  Liability.  If Mortgagor consists of more than one person,
the obligations and liabilities of each such person hereunder shall be
joint and several.

          33.  Prepayment After Default.  If following the occurrence of
any default under this mortgage and an exercise by Mortgagee of its option
to declare the Debt immediately due, Mortgagor shall tender payment of an
amount sufficient to satisfy the entire Debt at any time prior to a sale of
the Mortgaged Property any such payment shall be accepted by Mortgagee only
if such payment is permitted at such time under the provisions of the
Credit Agreement.

          34.  Construction.  The terms of this Mortgage shall be construed
in accordance with the laws of the State of New Jersey.

          35.  Security Agreement.  This Mortgage constitutes both a real
property mortgage and a "security agreement" within the meaning of the
Uniform Commercial Code of the State of New Jersey and the Mortgaged
Property

                                    24

<PAGE>

includes both real and personal property and all other rights and interest,
whether tangible or intangible in nature, of Mortgagor in the Mortgaged
Property.  Mortgagor, by executing and delivering this Mortgage, has
granted to Mortgagee, as security for the Debt, a security interest in such
of the Mortgaged Property as is governed by the Uniform Commercial Code.
Upon the occurrence and continuation of an Event of Default hereunder,
Mortgagee, in addition to any other rights and remedies which it may have,
shall have and may exercise immediately and without demand, any and all
rights and remedies granted to a secured party upon default under the
Uniform Commercial Code including, without limiting the generality of the
foregoing, the right to take possession of such of the Mortgaged Property
as is governed by the Uniform Commercial Code personally, through an agent
or by means of a court-appointed receiver, and to take such other measures
as Mortgage may deem necessary for the care, protection and preservation of
such part of the Mortgaged Property.  Upon request or demand of Mortgagee,
Mortgagor shall at its expense assemble such of the Mortgaged Property as
is governed by the Uniform Commercial Code 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 reasonable legal
expense and attorneys' fees, incurred or paid by Mortgagee in protecting
the interest in the Mortgaged Property herein granted and in enforcing its
rights hereunder with respect to such part of the Mortgaged Property.  Any
notice of sale, disposition or other intended action by Mortgagee with
respect to such part of the Mortgaged Property sent to Mortgagor in
accordance with the provisions of this mortgage at least five (5) days
prior to the date of any such sale, disposition or other action, shall
constitute reasonable notice to Mortgagor, and the method of sale or
disposition or other intended action set forth or specified in such notice
shall conclusively be deemed to be commercially reasonable within the
meaning of the Uniform Commercial Code unless objected to in writing by
Mortgagor within three (3) days after receipt by Mortgagor of such notice.

          36.  Further Acts, etc.  Mortgagor will, at the cost of Mortgagor
and without expense to Mortgagee, do, execute, acknowledge and deliver all
and every such further acts, deeds, conveyances, mortgages, assignments,
notices of assignments, transfers and assurances as Mortgagee shall, from
time to time, require, for the better assuring, conveying, assigning,
transferring and confirming unto

                                    25

<PAGE>

mortgagee the property and rights hereby mortgaged or intended now or
hereafter so to be, or which Mortgagor may be or may hereafter become bound
to convey or assign to Mortgagee, or for carrying out the intention or
facilitating the performance of the terms of this Mortgage or for filing,
registering or recording this Mortgage and, on demand, will execute and
deliver and hereby authorizes Mortgagee to execute in the name of Mortgagor
to the extent Mortgagee may lawfully do so, one or more financing
statements, chattel mortgages or comparable security instruments, to
evidence more effectively the lien hereof upon the Mortgaged Property.

          37.  Headings, etc.  The headings and captions of various
paragraphs of this Mortgage are for convenience of reference only and are
not to be construed as defining or limiting, in any way, the scope or
intent of the provisions hereof.

          38.  Recording of Mortgage, etc.  Mortgagor forthwith upon the
execution and delivery of this Mortgage and thereafter, from time to time,
will cause this Mortgage, and any security instrument creating a lien or
evidencing the lien hereof upon the Mortgaged Property and each instrument
of further assurance to be filed, registered or recorded in such manner and
in such places as may be required by any present or future law in order to
publish notice of and fully to protect the lien hereof upon, and the
interest of Mortgagee in the Mortgaged Property.  Mortgagor will pay all
filing, registration or recording fees, and all expenses actually incurred
incident to the preparation, execution and acknowledgment of this Mortgage,
any mortgage supplemental hereto, any security instrument with respect to
the Mortgaged Property and any instrument of further assurance, and all
Federal, state, county and municipal taxes, duties, imposts, assessments
and charges (including, without limitation, documentary stamp taxes and
intangible personal property taxes) arising out of or in connection with
the execution and delivery of this Mortgage or the Debt secured hereby, any
mortgage supplemental hereto, any security instrument or financing
statement with respect to the Mortgaged Property or any instrument of
further assurance.  Mortgagor shall hold harmless and indemnify Mortgagee,
its successors and assigns, against any liability incurred by reason of the
imposition of any tax on the making and recording of this Mortgage.

                                    26

<PAGE>

          39.  Usury Laws.  This Mortgage, the Credit Agreement and the
Notes are subject to the express condition that at no time shall Mortgagor
be obligated or required to pay interest on the principal balance due under
the Notes at a rate which could subject the holder of the Notes to either
civil or criminal liability as a result of being in excess of the maximum
interest rate which Mortgagor is permitted by Law to contract or agree to
pay.  If by the terms of this Mortgage, the Credit Agreement or the Notes,
Mortgagor is at any time required or obligated to pay interest on the
principal balance due under the Notes at a rate in excess of such maximum
rate, the rate of interest under the Notes (and the Credit Agreement) shall
be deemed to be immediately reduced to such maximum rate and the interest
payable shall be computed at such maximum rate and all prior interest
payments in excess of such maximum rate shall be applied and shall be
deemed to have been payments in reduction of the principal balance of the
Notes.

          40.  Sole Discretion of Mortgagee.  Except as otherwise
specifically provided in this Mortgage, wherever pursuant to this Mortgage,
Mortgagee exercises any right given to it to consent or to withhold its
consent, to approve or disapprove, or any arrangement or term is to be
satisfactory to Mortgagee, the decision of Mortgagee to consent or to
withhold its consent, to approve or disapprove or to decide that
arrangements or terms are satisfactory or not satisfactory shall be in the
sole discretion of Mortgagee and shall be final and conclusive.

          41.  Recovery of Sums Required To Be Paid.  Mortgagee shall have
the right from time to time to take action to recover any sum or sums which
constitute a part of the Debt as the same become due, without regard to
whether or not the balance of the Debt shall be due, and without prejudice
to the right of Mortgagee thereafter to bring an action of foreclosure, or
any other action, f(r a default or defaults by Mortgagor existing at the
time such earlier action was commenced.

          42.  Absolute and Unconditional Obligation.  Mortgagor
acknowledges that Borrower's obligation to pay the Debt in accordance with
the provisions of the Notes, the Credit Agreement and the Loan Instruments
is and shall at all times continue to be absolute and unconditional in all
respects, and shall at all times be valid and enforceable irrespective of
any other agreements or circumstances of any

                                    27

<PAGE>

nature whatsoever which might otherwise constitute a defense to the Notes,
the Credit Agreement or any of the Loan Instruments or the obligation of
Borrowers thereunder to pay the Debt or the obligations of any other person
relating to the Notes, the Credit Agreement or any of the Loan Instruments
or the obligations of Borrowers under the Notes, the Credit Agreement or
any of the Loan Instruments, and to the full extent permitted by law,
Mortgagor absolutely, unconditionally and irrevocably waives any and all
right to assert any defense, setoff, counterclaim or crossclaim of any
nature whatsoever with respect to the obligation of Borrowers to pay the
Debt in accordance with the provisions of the Notes, the Credit Agreement
and the Loan Instruments or the obligations of any other person relating to
the Notes, the Credit Agreement or any of the Loan Instruments or the
obligations of Borrowers under the Notes, the Credit Agreement or any of
the Loan Instruments, or in any action or proceeding brought by Mortgagee
to collect the Debt, or any portion thereof, or to enforce, foreclose and
realize upon the lien and security interest created by this Mortgage or any
other document or instrument securing repayment of the Debt, in whole or in
part.

          43.  Indemnification; Waiver of Offset.

          (a)  If Mortgagee, Agent or any of the Secured Parties are made a
party  defendant  to  any  litigation  concerning  the  Notes,  the  Credit
Agreement,  this  Mortgage,  any other Loan  Instrument  or  the  Mortgaged
Property or any part thereof or interest therein, or the occupancy  thereof
by  Mortgagor,  then Mortgagor shall indemnify, defend and  hold  Mortgagee
and/or  such  Secured  Parties,  as the case  may  be,  harmless  from  all
liability  by  reason  of said litigation, including reasonable  attorneys'
fees and expenses incurred by Mortgagee and/or such Secured Parties, as the
case may be, in any such litigation, whether or not any such litigation  is
prosecuted to judgment.  If Mortgagee commences an action against Mortgagor
to enforce any of the terms hereof or because of the breach by Mortgagor of
any  of  the  terms hereof or for the recovery of any sum  secured  hereby,
Mortgagor shall pay the Mortgagee's attorneys' fees and expenses,  together
with  interest thereon at the Default Interest Rate from the date the  same
are  paid to the date of reimbursement by Mortgagor and the right  to  such
reasonable attorneys' fees and expenses shall be deemed to have accrued  on
the  commencement of such action, and shall be enforceable whether  or  not
such action is prosecuted to judgment.  If

                                    28

<PAGE>

Mortgagor breaches any term of this Mortgage, the Mortgagee may engage an
attorney or attorneys to protect Mortgagee's rights hereunder, and in the
event of such engagement following any breach by Mortgagor, Mortgagor shall
pay the Mortgagee's reasonable attorneys' fees and expenses so incurred,
whether or not an action is actually commenced against Mortgagor by reason
of breach.

          (b)  All sums secured by this Mortgage shall be paid in
accordance with the Credit Agreement, the Notes, and any other Loan
Instruments, as applicable, and without counterclaim, setoff, deduction or
defense and without abatement, suspension, deferment, diminution or
reduction, and the obligations and liabilities of Mortgagor hereunder shall
in no way be released, discharged or otherwise affected (except as
expressly provided herein) by reason of (i) any claim which any of the
Borrowers (or Mortgagor) have or might have against Mortgagee or any of the
Secured Parties or (ii) any default or failure on the part of the Mortgagee
to perform or comply with any of the terms hereof or of any other agreement
with any of the Borrowers (or Mortgagor).

          44.  Authority.  Mortgagor (and the undersigned representative of
Mortgagor) has full power, authority and legal right to execute this
Mortgage and to mortgage, give, grant, bargain, sell, alien, enfeoff,
convey, confirm and assign the Mortgaged Property pursuant to the terms
hereof and to keep and observe all of the terms of this mortgage on
Mortgagor's part to be kept and observed.

          45.  Actions and Proceedings.  Mortgagee shall have the right to
appear in and defend any action or proceeding brought with respect to the
Mortgaged Property and to bring any action or proceeding, in the name and
on behalf of Mortgagor, which the Mortgagee, in its reasonable discretion,
feels should be brought to protect the Mortgagee's interest in the
Mortgaged Property.

          46.  Inapplicable Provisions.  If any term, covenant or condition
of this Mortgage shall be held to be invalid, illegal or unenforceable in
any respect, this mortgage shall be construed without such provision.

          47. Duplicate originals.  This Mortgage may be executed in any
number of duplicate originals and each such

                                    29

<PAGE>

duplicate original shall be deemed to constitute but one and the same
instrument.

          48.  Certain Definitions.  Unless the context clearly indicates a

          49.  Remedies Not Exclusive.  Mortgagee shall be entitled to
enforce payment and performance of any indebtedness or obligations secured
hereby and to exercise all rights and powers granted under this Mortgage or
under the Credit Agreement or the Notes or under any of the Loan
Instruments or under any Laws now or hereafter in force, notwithstanding
some or all of the said indebtedness and obligations secured hereby may now
or hereafter be otherwise secured, whether by mortgage, deed of trust,
pledge, lien, assignment or otherwise.  Neither the acceptance of this

Mortgage and any other security now or hereafter held

                                    30

<PAGE>

by Mortgagee, in such order and manner as it may in its absolute discretion
determine.  No remedy herein conferred upon or reserved to Mortgagee is
intended to be exclusive of any other remedy herein or by Law provided or
permitted, but each shall be cumulative and shall be in addition to every
other remedy given hereunder or now or hereafter existing at Law or in
equity or by statute.  Every right, power or remedy given by the Credit
Agreement, this Mortgage or any of the Loan Instruments to Mortgagee may be
exercised, concurrently or independently, from time to time and as often as
may be deemed expedient by Mortgagee.  Every right, power or remedy given
by this Mortgage to the Mortgagee may be exercised by Agent on behalf of
all Secured Parties pursuant to the Credit Agreement, whether so expressed
or not.

          50.  Joinder of Individual Special CO-Agent.  An individual,
appointed by Agent in its discretion, may be joined as special co-agent (in
such capacity, the "Special Co-Agent") hereunder in order to comply with
any legal requirements respecting agents under mortgages of property in the
jurisdiction in which the Mortgaged Property or any part thereof is or may
be situated so that if, by any present or future law in New Jersey or in
any jurisdiction in which it may be necessary to perform any act in the
exercise of the rights of Mortgagee hereunder, the Agent shall be
incompetent or unqualified to so act, then all of the acts required to be
performed in such jurisdiction in the exercise of the rights of Mortgagee
hereunder created hereby shall be performed by the Special CO-Agent and the
Agent jointly, or the Special Co-Agent acting alone.  In case the Special
Co-Agent shall resign or be removed, or die or become incapable of acting,
Mortgagee's interest in the Mortgaged Property, and all rights, powers,
trusts, duties and obligations of Mortgagee shall, so far as permitted by
law, vest in and be exercised by the Agent, unless and until a successor
Special Co-Agent shall be appointed.  The Special Co-Agent shall not be
personally liable by reason of any act or omission of the Agent or any co-
agent or separate agent or by reason of any act or omission of the Special
Co-Agent taken or omitted to be taken pursuant to written instructions
received by him from the Agent.  Notice to the Agent or a co-agent or
separate agent shall not constitute notice to the Special Co-Agent unless
and until such notice is actually received by the Special Co-Agent.

                                    31

<PAGE>

          51.  Relationship.  The relationship of Mortgagee to Mortgagor
hereunder is strictly and solely that of lender and borrower and nothing
contained in the Notes, this Mortgage, the Credit Agreement, or any other
Loan Instrument is intended to create, or shall in any event or under any
circumstance be construed as creating, a partnership, joint venture,
tenancy-in-common, joint tenancy or other relationship of any nature
whatsoever between Mortgagee and Mortgagor other than as lender and
borrower.

          52.  Waiver of Notice.  Mortgagor shall not be entitled to any
notices of any nature whatsoever from Mortgagee except with respect to
matters for which this Mortgage specifically and expressly provides for the
giving of notice by Mortgagee to Mortgagor and Mortgagor hereby expressly
waives the right to receive any notice from Mortgagee with respect to any
matter for which this mortgage does not specifically and expressly provide
for the giving of notice by Mortgagee to Mortgagor.

          53.  Waiver of Trial by Jury.  Mortgagor hereby irrevocably and
unconditionally waives, and Mortgagee by its acceptance of the Notes and
this Mortgage irrevocably and I unconditionally waives, any and all rights
to trial by jury in any action, suit or counterclaim arising in connection
with, out of or otherwise relating to the Notes, this Mortgage, the Credit
Agreement, or the other Loan Instruments.

          54.  Waiver of Statutory Rights.  Mortgagor shall not and will
not apply for or avail itself of any appraisement, valuation, stay,
extension or exemption laws, or any so-called "moratorium laws," now
existing or hereafter enacted, in order to prevent or hinder the
enforcement or foreclosure of this Mortgage, but hereby waives the benefit
of such laws to the full extent that Mortgagor may do so under applicable
law.  Mortgagor, for itself and all who may claim through or under it,
waives any and all right to have the property and estates comprising the
Mortgaged Property marshalled upon any foreclosure of the lien of this
Mortgage and agrees that any court having jurisdiction to foreclose such
lien may order the Mortgaged Property sold as an entirety.  Mortgagor
hereby waives for itself and all who may claim through or under it, and to
the full extent Mortgagor may do so under applicable law, any and all
rights of redemption from sale under any order or

                                    32

<PAGE>

decree of foreclosure of this Mortgage or granted under any statute now
existing or hereafter enacted.

          55.  Credit Agreement.  This Mortgage is subject to all of the
terms, covenants and conditions of the Credit Agreement, which Credit
Agreement and all of the terms, covenants and conditions thereof are by
this reference incorporated herein and made a part hereof with the same
force and effect as if set forth at length herein.  The proceeds of the
Funding Loans and Debt Service Loans secured hereby are to be advanced by
Mortgagee to Mortgagor in accordance with the provisions of the Credit
Agreement.  Mortgagor shall observe and perform all of the terms, covenants
and conditions of the Credit Agreement on Mortgagor's part to be observed
or performed.  All advances made and all indebtedness arising and accruing
under the Credit Agreement with respect to the Funding Loans or Debt
Service Loans thereunder from time to time shall be secured hereby.  In the
event of any conflict or ambiguity between the terms, covenants and
conditions of this Mortgage and the Credit Agreement, the terms, covenants
and conditions which shall enlarge the rights and remedies of Mortgagee and
the interest of Mortgagee in the Mortgaged Property, afford Mortgagee
greater financial security in the Mortgaged Property and better assure
Payment of the Debt in full, shall control.

          56.  No Oral Change.  This Mortgage may only be modified or
amended by an agreement in writing signed by Mortgagor and Mortgagee, and
may only be released, discharged or satisfied of record by an agreement in
writing signed by Mortgagee.  No waiver of any term, covenant or provision
of this Mortgage shall be effective unless given in writing by Mortgagee
and if so given by Mortgagee shall only be effective in the specific
instance in which given.  Mortgagor acknowledges that the Notes, this
Mortgage, the Credit Agreement and the other Loan Instruments set forth the
entire agreement and understanding of Mortgagor and Borrowers with respect
to the Debt secured hereby and that no oral or other agreements,
understanding, representation or warranties exist with respect to the Debt
secured hereby other than those set forth in the Notes, this Mortgage, the
Credit Agreement and the other Loan Instruments.

          57.  True Copy.  Mortgagor acknowledges receipt of a true copy of
this Mortgage.

covenants and conditions of this Mortgage supersede and restate in their
entirety the terms, covenants and conditions of the Existing mortgage.
