     TO HAVE AND TO HOLD the Mortgaged Property hereby conveyed or mentioned and
intended so to be, unto Mortgagee, to its own use forever.

     PROVIDED ALWAYS,  this instrument is upon the express  condition that, upon
payment in full of all Obligations and termination of the Revolving Credit, then
this Mortgage and the estate hereby granted shall cease and become void.

     MORTGAGOR  REPRESENTS,  COVENANTS AND WARRANTS to and with  Mortgagee  that
until the Obligations are fully repaid and the Revolving Credit is terminated:

     1.  Payment  and   Performance.   Mortgagor  shall  pay  to  Mortgagee  all
Obligations, in accordance with the terms of the Loan Documents. Mortgagor shall
perform and comply with all the agreements,  conditions,  covenants,  provisions
and  stipulations of this Mortgage and the other Loan Documents to which it is a
party.  Mortgagor  shall  timely  perform all of its  obligations  and duties as
landlord  under any  Leases of any  portion  of the  Mortgaged  Property  now or
hereafter in effect.

     2.  Warranty of Title.  Mortgagor  warrants  to  Mortgagee  that  Mortgagor
possesses  good and  marketable  unencumbered  fee simple title to the Mortgaged
Property,  except  for  those  title  exceptions  listed in the  lender's  title
insurance  policy  approved by and issued to Mortgagee  insuring the priority of
the lien of this Mortgage.

     3. Maintenance of Mortgaged Property. Mortgagor shall keep and maintain the
Mortgaged  Property  and the  abutting  sidewalks  and  curbs in good  order and
condition  (ordinary wear and tear  excepted) in compliance  with all applicable
laws and in a rentable and  tenantable

                                       3


state of repair, and will make, as and when necessary, all repairs, renewals and
replacements,  structural and nonstructural, exterior and interior, ordinary and
extraordinary,  foreseen and unforeseen.  Mortgagor shall abstain from and shall
not permit the commission of waste in or about the Mortgaged Property, shall not
remove or  demolish  any  portion  of the  Improvements,  or,  other than in the
ordinary course of business, any machinery, equipment or other personal property
located thereon or alter the structural  character or exterior appearance of any
Improvements,  without the prior written  consent of Mortgagee.  Mortgagor shall
not permit the Mortgaged  Property to become  deserted or  abandoned.  Mortgagor
shall  operate the Mortgaged  Property as it is currently  being  operated,  and
Mortgagor  shall not change the use of the  Mortgaged  Property from its current
use without first obtaining the prior written consent of Mortgagee.

     4. Insurance.

               (i) Mortgagor  shall provide and maintain  insurance  coverage in
accordance with the terms of the Loan Agreement.

          (b) Reserved.

          (c) If the  insurance,  or  any  part  thereof,  shall  expire,  or be
canceled,  or become  void or voidable  by reason of  Mortgagor's  breach of any
condition   thereof,   or  if  Mortgagee   determines   that  such  coverage  is
unsatisfactory  by reason of the  failure or  impairment  of the  capital of any
company  in which the  insurance  may then be carried  or the  lowering  of such
insurance  carrier's  rating from its rating on the date  hereof,  or if for any
reason whatever the insurance shall, in Mortgagee's  reasonable  discretion,  be
unsatisfactory  to  Mortgagee,  Mortgagor  shall  place  new  insurance  on  the
Mortgaged Property, reasonably satisfactory to Mortgagee.

          (d) In the event of loss, Mortgagor will give prompt notice thereof to
Mortgagee,  and  Mortgagee  may  make  proof  of loss if not  made  promptly  by
Mortgagor;  provided,  however,  that any  adjustment  of a proof of loss  shall
require the prior written  consent of Mortgagee.  Such policies of insurance and
all renewals thereof are hereby assigned to Mortgagee as additional security for
payment of the  Obligations  and Mortgagor  hereby agrees that after an Event of
Default any values available  thereunder upon cancellation or termination of any
of said  policies  or  renewals,  whether in the form of return of  premiums  or
otherwise,  shall be payable to  Mortgagee  as assignee  thereof.  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.

          (e)  Mortgagee  shall  retain  and  apply  the  proceeds  of any  such
insurance to reduction of the indebtedness  secured hereby, or to restoration or
repair  of the  property  damaged,  in  accordance  with  the  terms of the Loan
Agreement.  Mortgagee's  application  of insurance  proceeds to reduction of the
indebtedness  secured by this  Mortgage  shall not excuse or modify  Mortgagor's
obligation  to continue to pay the  installments  of interest  and/or  principal
required under the Notes unless the amount of such insurance  proceeds  received
by Mortgagee is  sufficient  to repay in full all  interest,  principal  and all
other sums required to be paid to Mortgagee under the Notes and this Mortgage.

                                       4


     5. Taxes and Other Charges.

          (a)  Mortgagor  shall pay when due and  payable  and prior to the time
interest,  penalties  or  additions  are due  thereon,  without  any  deduction,
defalcation  or abatement,  all real estate  taxes,  municipal  assessments  and
liens,  water  and sewer  rents,  and other  governmental  levies  and all other
charges  or claims of every  nature  and kind  which  may be  assessed,  levied,
imposed,  suffered, placed 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 or other sale  (collectively  "Taxes");  and upon request by Mortgagee,
Mortgagor shall produce to Mortgagee,  official  receipts for the payment of the
Taxes;  provided,  however, that if, pursuant to this Mortgage,  Mortgagor shall
have deposited with Mortgagee before the due date thereof sums sufficient to pay
any Taxes,  and Mortgagor is not otherwise in default under the Loan  Documents,
the Taxes shall be paid by Mortgagee.  Mortgagor will not apply for or claim any
deduction, by reason of this Mortgage, from the taxable value of all or any part
of the Mortgaged Property. No credit shall be claimed or allowed on the interest
payable on the Notes because of any Taxes paid.

          (b) Mortgagor shall procure for Mortgagee,  at Mortgagor's  expense, a
real estate tax reporting service  throughout the term of this Mortgage,  and if
Mortgagor  fails to do so,  Mortgagee  may  obtain  such  service  directly  and
Mortgagor shall, upon demand, reimburse Mortgagee for the cost of such service.

     6. Installments for Taxes and Other Charges. Without limiting the effect of
Paragraphs 4 and 5, while an Event of Default exists, upon Mortgagee's  request,
Mortgagor  shall pay to  Mortgagee,  monthly  with the monthly  installments  of
interest or principal and interest, an amount equal to one-twelfth (1/12) of the
annual  Taxes  ("Escrow  Items").  On  demand  by  Mortgagee  from time to time,
Mortgagor shall pay to Mortgagee any additional sums necessary to pay the Escrow
Items,  all as estimated by  Mortgagee.  The amounts paid by Mortgagor  shall be
security for the Escrow Items and shall be used in payment  thereof if Mortgagor
is not otherwise in default under the Loan Documents. No amount so paid shall be
deemed to be trust funds but may be commingled  with general funds of Mortgagee,
and no interest shall be payable  thereon.  If,  pursuant to the Loan Documents,
the entire  unpaid  principal  debt  secured  hereby  becomes  due and  payable,
Mortgagee shall have the right,  at its election,  to apply any amount of Escrow
Items held by  Mortgagee  against the entire  indebtedness  secured  hereby.  At
Mortgagee's  option,  Mortgagee from time to time may waive,  and after any such
waiver may reinstate,  the  provisions of this  Paragraph  requiring the monthly
payments of Escrow Items.

     7. Corporate Existence and Taxes. Reserved.

     8.  Documentary  and Other Stamps.  If at any time the United  States,  the
state in which the Mortgaged  Property is located or any  political  subdivision
thereof,  or any  department  or bureau of any of the  foregoing  shall  require
documentary,  revenue  or other  stamps or taxes on the Notes or this  Mortgage,
Mortgagor on demand  shall pay for them with any  interest or penalties  payable
thereon.

                                       5


     9. Other  Taxes.  If any law or ordinance  now or  hereafter  imposes a tax
directly or  indirectly  on  Mortgagee  with respect to the  Mortgaged  Property
(other  than an income  tax,  withholding  tax or foreign  taxes),  the value of
Mortgagor's  equity  therein,  or the  indebtedness  evidenced  by the Notes and
secured by this Mortgage,  Mortgagor  shall have the right to contest such taxes
but  shall  promptly  pay such tax  during  the  pendency  of such  contest.  If
Mortgagor fails to pay such tax or if Mortgagor is not lawfully permitted to pay
such tax, Mortgagee,  at its election,  shall have the right at any time to give
Mortgagor  written notice  declaring that the principal  debt, with interest and
other appropriate charges,  shall be due on a specified date not less than sixty
(60) days thereafter; provided, however, that such election shall be ineffective
if, prior to the specified date, Mortgagor lawfully pays the tax (in addition to
all other  payments  required  hereunder)  and agrees to pay the tax whenever it
becomes due and payable thereafter, which agreement shall then constitute a part
of this Mortgage.

     10.  Security  Agreement.  This Mortgage  constitutes a security  agreement
under the Uniform  Commercial  Code in effect in the state where the Real Estate
is situated and Mortgagor hereby grants to Mortgagee a security  interest in all
that property  (and the proceeds  thereof)  included in the  Mortgaged  Property
which might be deemed "personal  property".  Mortgagor shall deliver or file and
refile any financing  statements,  continuation  statements,  or other  security
agreements  Mortgagee  may request from time to time to confirm the lien of this
Mortgage  with  respect  to  such  property.  Without  limiting  the  foregoing,
Mortgagor hereby  irrevocably  appoints Mortgagee attorney in fact for Mortgagor
to deliver and file such  instruments for and on behalf of Mortgagor.  Mortgagor
shall not  change  its  principal  place of  business  or state of  organization
without giving Mortgagee at least thirty (30) days prior written notice thereof,
which notice shall be accompanied  by new financing  statements in the same form
as the financing statements delivered to Mortgagee on the date hereof except for
the  change of  address.  Mortgagor  covenants  to retain  all of the  Mortgaged
Property  within  the  county in which the Real  Estate is  located,  other than
equipment  which may be removed in the  ordinary  course of  business.  Upon any
Event of Default under this Mortgage,  Mortgagee  shall have, in addition to any
other  rights  and  remedies  under the Loan  Documents,  all of the  rights and
remedies  granted to a secured  party  under the  Uniform  Commercial  Code with
respect to all personal property. Mortgagor agrees that the personal property is
not and will not be used or acquired for personal, family or household purposes.
Upon an  Event of  Default  under  this  Mortgage,  (i)  Mortgagee  may  require
Mortgagor to assemble the personal  property or any portion thereof,  at a place
designated by Mortgagee and reasonably  convenient to both parties, and promptly
to deliver such personal  property to Mortgagee,  or an agent or  representative
designated by it, (ii) Mortgagee,  and its agents and representatives shall have
the right to enter upon the Mortgaged  Property to exercise  Mortgagee's  rights
hereunder,  and (iii)  Mortgagee  may sell,  lease or  otherwise  dispose of the
personal  property at public sale, with or without having the personal  property
at the place of sale,  and upon such terms and in such manner as  Mortgagee  may
determine.  Mortgagee  may be a purchaser at any such sale.  Unless the personal
property is perishable or threatens to decline speedily in value or is of a type
customarily sold on a recognized market, Mortgagee shall give Mortgagor ten (10)
days'  prior  written  notice  of the time and place of any  public  sale of the
personal property or other intended  disposition  thereof,  and Mortgagor agrees
that such notice is reasonable.  To the extent  permitted by law,  Mortgagor and
Mortgagee  agree that the items set forth on the financing  statements  shall be
treated as part of the Real Estate and Improvements  regardless of the fact that
such items are set forth in the financing statement. Such items are

                                       6


contained in the financing  statements to create a security interest in favor of
Mortgagee in the event such items are  determined to be personal  property under
the law.  Notwithstanding any release of any or all of that 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  interest  created
hereby and referred to above until the repayment or  satisfaction in full of the
obligations of Mortgagor as are now or hereafter evidenced by the Notes.

     11. Compliance with Law and Other Matters.

          (a)  Mortgagor  shall  comply  with  all  material  laws   ordinances,
regulations and orders (collectively  "Laws") of all federal,  state,  municipal
and other governmental  authorities  ("Governmental  Authority") relating to the
Mortgaged Property and the use and occupancy of the Mortgaged Property.

          (b)  Mortgagor  shall at all times  maintain  the legal  existence  of
Mortgagor  and, if and to the extent  required by applicable law to enable it to
own and operate the Mortgaged  Property and to perform its obligations under the
Notes and this Mortgage,  its qualification to do business in the state in which
the Mortgaged  Property is located and, from time to time,  file and record such
certificates  or  instruments  as may be necessary or desirable to maintain such
existence  and  qualification  and to  permit  the  continued  operation  of its
business.

          (c) Mortgagor  will not initiate,  join in or consent to any change in
any private  restrictive  covenant,  zoning ordinance or other public or private
restrictions  limiting or defining  the uses which may be made of the  Mortgaged
Property or any part thereof,  without the prior  written  consent of Mortgagee,
which consent shall not be unreasonably withheld.

          (d)  Mortgagor  will comply with all material  restrictive  covenants,
easement  agreements  and  other  recorded  documents  affecting  the  Mortgaged
Property.  Mortgagor  will not  record or permit to be  recorded  any  document,
instrument,  agreement or other writing against the Mortgaged  Property  without
the prior written consent of Mortgagee,  which consent shall not be unreasonably
withheld.

          (e)  Mortgagor  shall  pay  when due all  utility  charges  which  are
incurred by Mortgagor, whether public or private and whether or not such charges
are or may become liens on the Mortgaged Property.

          (f)  Mortgagor  agrees to subject to the lien of this  Mortgage,  in a
form reasonably  satisfactory  to Mortgagee,  all additional  strips,  gores, or
parcels of land acquired by Mortgagor or any leasehold interest therein acquired
by Mortgagor,  which adjoin the Mortgaged Property,  and all additional interest
in and  easements,  rights and  appurtenances  to the Mortgaged  Property  above
described  and in and to said  strips,  gores and  parcels,  and to execute  and
deliver  to  Mortgagee  such  security  agreements  and  extensions  thereof  as
Mortgagee  reasonably  may request and  promptly to pay  Mortgagee's  reasonable
costs (including  reasonable  attorneys'  fees) in connection  therewith and the
title insurance  premiums necessary to insure such additional land is encumbered
by this Mortgage as a first lien thereon.

                                       7


          (g) While an Event of Default exists,  Mortgagor  agrees to deliver to
Mortgagee,  within fifteen (15) days after written request by Mortgagee, any and
all plans, specifications, renderings, studies, analyses, reports or evaluations
in the possession of Mortgagor with respect to the physical condition of, or the
development or use of, the Mortgaged Property or any part thereof.

          (h) Mortgagor shall not suffer or permit the Mortgaged  Property to be
used by the public in such manner as might reasonably tend to impair Mortgagor's
title to the  Mortgaged  Property or any portion  thereof,  or in such manner as
might  reasonably  make  possible a right or rights of adverse  usage or adverse
possession  by the public,  as such,  or of implied  dedication of the Mortgaged
Property or any portion thereof.

     12. Inspection. Reserved.

     13. Declaration of No Set-Off. Reserved.


     14.  Required  Notices.  Mortgagor shall notify  Mortgagee  promptly of the
occurrence of any of the following:

          (a) a fire or other  casualty  causing damage in excess of $100,000 to
the Mortgaged Property,

          (b) receipt of notice of eminent domain proceedings or condemnation of
the Mortgaged Property,

          (c)  receipt  of a material  notice  from any  Governmental  Authority
relating to the condition, structure, use or occupancy of the Mortgaged Property
or any real estate adjacent to the Mortgaged Property,

          (d) receipt of any notice of default or threatened default,  notice of
lease  termination  or similar  material  notice from a tenant  under any of the
Leases, or

          (e) a material change in the occupancy of the Mortgaged Property.

     15. Condemnation.

          (a) In the  event of any  condemnation  or  taking  of any part of the
Mortgaged Property by eminent domain,  alteration of the grade of any street, or
other injury to or decrease in the value of the Mortgaged Property by any public
or quasi-public  authority or  corporation,  all proceeds (that is, the award or
agreed  compensation for the damages  sustained)  allocable to Mortgagor,  after
deducting therefrom all costs and expenses  (regardless of the particular nature
thereof and whether  incurred with or without suit)  including  attorneys'  fees
incurred by Mortgagee in connection with the collection of such proceeds,  shall
be  applied  as set forth in this  Section  15. No  settlement  for the  damages
sustained shall be made by Mortgagor without Mortgagee's prior written approval,
which approval  shall not be  unreasonably  withheld.  All the proceeds shall be
applied in the order and in the amounts  that  Mortgagee,  in  Mortgagee's  sole
discretion,  may elect, to the payment of principal (whether or not then due and
payable), interest

                                       8


or any other  sums  secured  by this  Mortgage.  Notwithstanding  the  foregoing
sentence and provided  that no Event of Default has occurred and is  continuing,
Mortgagor  may first  apply such  proceeds  for the sole  purpose  of  altering,
restoring or rebuilding  any part of the Mortgaged  Property which may have been
altered, damaged or destroyed as a result of the taking,  alteration of grade or
other injury to the Mortgaged Property.

          (b) If prior to the receipt of the proceeds by Mortgagee the Mortgaged
Property shall have been sold on foreclosure of this Mortgage,  Mortgagee  shall
have the right to receive the proceeds to the extent of:

               (i) the full  amount of all such  proceeds  if  Mortgagee  is the
successful purchaser at the foreclosure sale, or

               (ii) if any one other than Mortgagee is the successful  purchaser
at  the  foreclosure  sale,  any  deficiency  (as  hereinafter  defined)  due to
Mortgagee in connection with the foreclosure  sale, with interest thereon at the
rate  set  forth  in  the  Notes,   and  reasonable   counsel  fees,  costs  and
disbursements  incurred by  Mortgagee  in  connection  with  collection  of such
proceeds of condemnation and the establishment of such deficiency.  For purposes
of this subparagraph (b) (ii), the word "deficiency" shall be deemed to mean the
difference between (A) the net sale proceeds actually received by Mortgagee as a
result  of such  foreclosure  sale  less any  costs  and  expenses  incurred  by
Mortgagee in connection  with  enforcement  of its rights under the Notes,  this
Mortgage  and the  other  Loan  Documents  and (B) the  aggregate  amount of the
Obligations.

          (c) Mortgagee shall have the right to prosecute to final determination
or  settlement  an  appeal  or  other  appropriate  proceedings  in the  name of
Mortgagee or Mortgagor,  for which Mortgagee is hereby appointed  irrevocably as
attorney-in-fact  for  Mortgagor,  which  appointment,  being for  security,  is
irrevocable.  In  that  event,  the  expenses  of  the  proceedings,   including
reasonable  counsel fees, shall be paid first out of the proceeds,  and only the
excess,  if any,  paid to  Mortgagee  shall be credited  against the amounts due
under this Mortgage.

          (d) Nothing  herein  shall  limit the rights  otherwise  available  to
Mortgagee,  at law or in equity,  including the right to intervene as a party to
any condemnation proceeding.

     16. Completion of Construction. Mortgagor shall complete and timely pay for
any construction  which is commenced at any time on the Mortgaged  Property free
of any mechanics liens or other liens. All such  construction  shall comply with
all  applicable  Laws and shall be performed in a good and  workmanlike  manner.
Nothing contained in this Paragraph shall be deemed to waive any right Mortgagee
may have under the Loan  Documents  to  approve  construction  on the  Mortgaged
Property.

     17. Leases.

          (a) Mortgagor hereby represents that there are no leases or agreements
to lease all or any part of the  Mortgaged  Property  now in effect  except  the
Leases, if any, expressly approved in writing by Mortgagee. Mortgagor agrees not
to enter into any Leases or agreements to lease all or any part of the Mortgaged
Property or to modify, amend, terminate or consent to

                                       9


the  surrender of, or assign its interest in, any Leases or to permit the tenant
or subtenant  thereunder to  subordinate  its Leases to any lien  subordinate to
this Mortgage, without the prior written consent thereof by Mortgagee.

          (b) Upon  receipt by  Mortgagor,  from time to time,  of any  security
deposit,  prepaid rent (other than prepaid rent for the next succeeding calendar
month),  or similar payments by a tenant,  subtenant,  licensee or other user of
the Mortgaged  Property,  Mortgagor  shall deposit such sum in a separate escrow
account  with a national  or state bank having  banking  offices in the state in
which the Mortgaged Property is located. Mortgagor shall promptly give Mortgagee
written notice of the name and address of the bank and the account number of the
escrow account.  Mortgagor shall also give written authorization to such bank to
permit Mortgagee to receive any information requested by Mortgagee from the bank
as to the status and balance of such  account.  Said sums shall be held in trust
by Mortgagor  and disbursed  only upon the prior written  approval of Mortgagee,
which approval shall not be unreasonably  withheld. The prior written consent of
Mortgagee shall not be required when by law (or agreement approved by Mortgagee)
Mortgagor  is required to return any of such sums to the party who  deposited it
with Mortgagor.  Mortgagor hereby assigns all of such bank accounts to Mortgagee
as collateral  security for the Obligations  and Mortgagor  agrees that after an
Event of Default by Mortgagor  under the Loan  Documents,  the sums in said bank
accounts  shall,  at the  election  of  Mortgagee,  be payable to  Mortgagee  as
assignee of such bank account;  provided,  however, that Mortgagee shall have no
liability for any prior misapplication of said sums by Mortgagor.

     18. No Other Financing or Liens. Reserved.

     19. No Transfer. Reserved.

     20. Hazardous Materials. Reserved.

     21. Right to Remedy Defaults.

          (a) If Mortgagor should fail to pay corporate taxes,  Taxes,  sums due
under any Permitted Lien against the Mortgaged Property,  or insurance premiums,
or any  sums  payable  by  Mortgagor  pursuant  to the  Leases,  or fail to make
necessary  repairs to the Mortgaged  Property,  or permit waste to the Mortgaged
Property,  shall otherwise fail to perform its obligations  under this Mortgage,
Mortgagee,  at its election,  after giving  Mortgagor  three (3) business  days'
notice of such  failure  (except in an  emergency  in which case no such  notice
shall be required),  shall have the right to make any payment or expenditure and
to take any action which Mortgagor should have made or taken, or which Mortgagee
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. Such payment by Mortgagee shall not
release  Mortgagor  from  Mortgagor's  obligations  or  constitute  a waiver  of
Mortgagor's default under this Mortgage.

          (b) Mortgagee in making any payment authorized by this Paragraph:  (i)
relating  to  Taxes  and  corporate  taxes,  may do so  according  to any  bill,
statement  or estimate  procured  from the  appropriate  public  office  without
inquiry  into the  accuracy  of such bill,  statement  or  estimate  or into the
validity of the Tax or claim thereof; or (ii) for the purchase,

                                       10


discharge, compromise or settlement of any other Lien, may do so without inquiry
as to the  validity  or amount of any claim for lien which may be  asserted;  or
(iii) for the payment of any sums to cure any default  under the Leases,  may do
so  without  inquiry  as to  the  validity  or  amount  of any  claimed  default
thereunder. In exercising its rights hereunder Mortgagee may, but need not, make
full  or  partial  payments  on any  Lien,  if  any,  and  purchase,  discharge,
compromise  or settle any tax lien or other Lien or title or claim  thereof,  or
redeem  from any tax sale or  forfeiture  effecting  the  Mortgaged  Property or
contest any tax. Such  payments will be deemed made by Mortgagee at  Mortgagor's
request and  Mortgagee  shall be subrogated to any and all rights and liens held
by the  owner or  holder  of any  Lien,  irrespective  of  whether  such Lien is
released or satisfied.

          (c) All such sums, as well as costs, advanced by Mortgagee pursuant to
this Mortgage shall be due  immediately  from  Mortgagor to Mortgagee,  shall be
secured by this Mortgage and the lien therefore shall relate back to the date of
this  Mortgage,  and such sums,  as well as costs,  shall bear  interest  at the
default rate specified by Term Loan B Note from the date of payment by Mortgagee
until the date of repayment to Mortgagee.

     22. Events of Default.  Each of the following shall constitute an "Event of
Default" under this Mortgage:

          (a)  Mortgagor's  non-performance  or  non-compliance  with any of the
other agreements, conditions, covenants, provisions or stipulations contained in
this Mortgage and the continuance of such default for thirty (30) days after the
occurrence thereof;

          (b) The occurrence of an Event of Default under the Loan Agreement.

     23. Remedies.

          (a) Upon the occurrence of an Event of Default, Mortgagee may exercise
all rights and remedies under the Loan Agreement.

          (b) Upon the occurrence of an Event of Default, or Mortgagor's failure
to pay the Obligations when such  Obligations  become due and payable because of
maturity or because of acceleration after the occurrence of an Event of Default,
then forthwith:

               (i)  Foreclosure.  Mortgagee  may 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  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  Obligations,  with interest at the rate set forth in the
Loan Agreement, together with all other sums due by Mortgagor in accordance with
the provisions of this Mortgage and the other Loan Documents, 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,
payments on Liens,  insurance  premiums,  utilities or repairs to the  Mortgaged
Property and other sums which Mortgagee is permitted to advance  pursuant to the
terms of this Mortgage,  all costs of suit,  together with interest at such rate
on any judgment obtained by Mortgagee from and after the date of any

                                       11


sheriff or other  judicial sale until actual  payment is made of the full amount
due Mortgagee, and all Expenses.

               (ii)  Possession.  Mortgagee  may enter  into  possession  of the
Mortgaged Property,  with or without legal action, collect therefrom all rentals
(which term shall also include sums payable for use and  occupation)  and, after
deducting  all costs of collection  and  administration  expense,  apply the net
rentals to any or all of the  following in such order and amounts as  Mortgagee,
in Mortgagee's sole discretion, may elect: the payment of any sums due under any
Lien,  Taxes,  insurance  premiums and all other  carrying  charges,  and to the
maintenance, repair or restoration of the Mortgaged Property, and on account and
in reduction of the principal or interest, or both, secured by this Mortgage; in
and for that purpose,  Mortgagor hereby assigns to Mortgagee all rentals due and
to become due under the Leases or rights to use and  occupation of the Mortgaged
Property hereafter created,  as well as all rights and remedies provided in such
Leases or at law or in equity for the  collection of the rentals.  The taking of
possession and collections of rents by Mortgagee shall not be construed to be an
affirmation of any Leases or acceptance of attornment with respect to any Leases
of all or any portion of the Mortgaged Property.  Mortgagee,  in its discretion,
may, as attorney in fact or agent of Mortgagor,  or in its own name as Mortgagee
and under the powers  herein  granted,  hold,  operate,  manage and  control the
Mortgaged Property and conduct the business, if any, thereof,  either personally
or by its agents, and with full power to use such measures,  legal or equitable,
as in its  discretion or in the  discretion of its  successors or assigns may be
deemed  proper or  necessary  to enforce  the payment or security of the avails,
rents, issues, and profits of the Mortgaged Property,  including actions for the
recovery of rent, actions in forcible detainer and actions in distress for rent,
and with full power:  to cancel or terminate  any Leases for any cause or on any
ground which would  entitle  Mortgagor to cancel the same; to elect to disaffirm
any Leases which are then subordinate to the lien of this Mortgage; to extend or
modify  any then  existing  Leases  and to make new  Leases,  which  extensions,
modifications  and new Leases may provide for terms to expire, or for options to
extend or renew terms to expire,  beyond the maturity  date of the  indebtedness
hereunder  and beyond the date of the issuance of a deed or deeds to a purchaser
or  purchasers at a foreclosure  sale, it being  understood  and agreed that any
such Leases,  and the options or other such provisions to be contained  therein,
shall be binding upon Mortgagor and all persons whose interests in the Mortgaged
Property are subject to the lien hereof and upon the  purchaser or purchasers at
any foreclosure sale, notwithstanding any redemption from sale, discharge of the
Mortgage  indebtedness,  satisfaction of any foreclosure  decree, or issuance of
any  certificate  of sale  or  deed to any  purchaser;  and to  enter  into  any
management, leasing or brokerage agreements covering the Mortgaged Property.

          (c)  Mortgagee  shall have the right,  from time to time,  to bring an
appropriate action to recover any Obligations  without prejudice to the right of
Mortgagee  thereafter to bring an action of mortgage  foreclosure,  or any other
action,  for any Event of Default by Mortgagor  existing at the time the earlier
action was commenced.

          (d) Any real estate sold pursuant to any writ of execution issued on a
judgment obtained by virtue of this Mortgage,  or pursuant to any other judicial
proceedings under the Mortgage, 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.

                                       12


          (e) Reserved.

          (f) Upon,  or at any time after the  filing of an action to  foreclose
this  Mortgage,  the court in which such  action is filed may, at the request of
Mortgagee, appoint a receiver of the Mortgaged Property. Such appointment may be
made either before or after sale,  with notice to Mortgagor,  without  regard to
the solvency or  insolvency  of Mortgagor  at the time of  application  for such
receiver and without regard to either the then value of the Mortgaged  Property,
the adequacy or  inadequacy  of any remedy  available at law, or the solvency or
insolvency of Mortgagor  and any other person  liable to pay such  indebtedness,
and  Mortgagee  hereunder  or any agent of  Mortgagee  may be  appointed as such
receiver.  Such  receiver  shall  have  the  power  to  perform  all of the acts
permitted  Mortgagee  pursuant  to  subparagraph  (b) (ii)  above and such other
powers which may be necessary or are customary in such cases for the protection,
possession,  control,  management and operation of the Mortgaged Property during
such period.

          (g) Mortgagee may, at its sole option, disaffirm and cancel any Leases
which are  subordinate  to this  Mortgage at any time before the  expiration  of
sixty  (60) days  after  Mortgagee  acquires  the legal  title to the  Mortgaged
Property by sheriff's deed or any other transfer of legal title to the Mortgaged
Property  pursuant to the  exercise of a remedy  hereunder  or  otherwise,  even
though Mortgagee shall have enforced such Leases,  collected rents thereunder or
taken any action that might be deemed by law to  constitute an affirmance of the
Leases.  Such  disaffirmance  shall be made by written  notice  addressed to the
applicable  tenants at the Mortgaged  Property or, at Mortgagee's  option,  such
other address of such tenants as may be provided in the Leases.

          (h)  Mortgagor,  for itself  and for all  persons  hereafter  claiming
through or under it or who may at any time  hereafter  become  holders of a Lien
junior to the lien of this Mortgage,  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 any of the  Obligations  marshalled  upon any  foreclosure  of this
Mortgage or of any other security for any of said indebtedness.

          (i) If Mortgagor or any party  comprising the Mortgagor is an occupant
of part or all of the  Mortgaged  Property,  they  shall  immediately  upon  any
acceleration  after an Event  of  Default  hereunder  surrender  the  possession
thereof to Mortgagee and if they remain in possession,  such possession shall be
as tenant at  sufferance of  Mortgagee,  and Mortgagor  agrees to pay monthly in
advance to Mortgagee  such rent for the  premises so occupied as  Mortgagee  may
reasonably  demand, and in default of so doing Mortgagor or any party comprising
the Mortgagor may be  dispossessed  by summary  proceedings or otherwise with or
without any action being brought to foreclose this Mortgage and without applying
for a receiver to collect the rents. In case of the appointment of a receiver of
rents and profits of the Mortgaged  Property,  the covenants of this Section may
be enforced by such receiver.

          (j) Upon any  sale  made  under or by  virtue  of this  Paragraph  23,
Mortgagee  may bid for and  then  acquire  the  Mortgaged  Property  or any part
thereof  and in lieu of  paying  cash  therefore  may  make  settlement  for the
purchase price by crediting upon the indebtedness of

                                       13


the  Mortgagor  secured by this  Mortgage  the net sales price  after  deducting
therefrom  the  expenses  of the sale and the costs of the  action and any other
sums which the Mortgagee is authorized to deduct under this Mortgage.

          (k) If  Mortgagee  shall have the right to  foreclose  this  Mortgage,
Mortgagor  authorizes Mortgagee at its option to foreclose this mortgage subject
to the rights of any tenants of the Mortgaged Property,  and the failure to make
any such tenants  parties  defendant to any such  foreclosure  proceeding and to
foreclose  their  rights will not be asserted by  Mortgagor  as a defense to any
proceeding instituted by Mortgagee to collect the indebtedness secured hereby or
any  deficiency  remaining  unpaid after the  foreclosure  sale of the Mortgaged
Property, it being expressly understood and agreed, however, that nothing herein
contained shall prevent Mortgagee from asserting in any proceeding disputing the
amount of the deficiency or the sufficiency of any bid at such foreclosure sale,
that any such tenancies adversely affect the value of the Mortgaged Property.

     24. Rights and Remedies Cumulative.

          (a) The rights and remedies of Mortgagee as provided in this  Mortgage
and the other Loan Documents and in the warrants  attached  thereto or contained
therein  shall  be  cumulative  and  concurrent;   may  be  pursued  separately,
successively or together against Mortgagor or against the Mortgaged Property, or
both, at the sole  discretion of Mortgagee,  and may be exercised as the need to
exercise  them shall  arise.  The failure to  exercise  any such right or remedy
shall in no event be construed as a waiver or release thereof.

          (b) Any failure by  Mortgagee  to insist upon  strict  performance  by
Mortgagor of any of the  provisions of this Mortgage or the other Loan Documents
shall not be deemed  to be a waiver  of any of the  terms or  provisions  of the
Mortgage  or the  other  Loan  Documents,  and  Mortgagee  shall  have the right
thereafter  to insist upon strict  performance  by  Mortgagor  of any and all of
them.

          (c) 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 or  discharged  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 other Loan  Documents,  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
consenting  to the  granting of any  easements  or  recordation  of  restrictive
covenants  affecting  the  Mortgaged  Property or by reason of any  agreement or
stipulation between any subsequent owner of the Mortgaged Property and Mortgagee
extending  the time or amount of payment or modifying the terms of this Mortgage
or the other  Loan  Documents  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 make  payments  according to the
terms of any such extension or modification agreement, unless expressly released
and discharged in writing by Mortgagee.

                                       14


          (d) Mortgagee may release,  regardless of  consideration,  any part of
the  security  held for the  Obligations  without,  as to the  remainder  of the
security,  in any way  impairing or affecting  the lien of this  Mortgage or its
priority over any subordinate lien.

          (e) For payment of the Obligations secured hereby Mortgagee may resort
to any other  security  therefore  held by Mortgagee in such order and manner as
Mortgagee may elect.

          (f) The receipt by Mortgagee of any sums from Mortgagor after the date
on which Mortgagee elects to accelerate the Obligations by reason of an Event of
Default  hereunder  shall not  constitute  a cure or waiver of such default or a
reinstatement  of this  Mortgage or the other Loan  Documents  unless  Mortgagee
expressly  agrees,  by written  notice to Mortgagor,  that such payment shall be
accepted as a cure or waiver of the default.

     25. Mortgagor's Waivers. Mortgagor hereby waives and releases:

          (a) all procedural errors, defects and imperfections in any proceeding
instituted by Mortgagee under the Notes,  this Mortgage or any of the other Loan
Documents;

          (b) all  benefit  that  might  accrue  to  Mortgagor  by virtue of any
present or future law,  exempting  the  Mortgaged  Property,  or any part of the
proceeds  arising  from  any  sale  thereof,  from  attachment,  levy or sale on
execution, or providing for any stay of execution,  exemption from civil process
or extension of time for payment; and

          (c) unless  specifically  required herein,  all notices of Mortgagor's
default or of Mortgagee's  election to exercise,  or Mortgagee's actual exercise
of, any option  under the  Leases,  the Notes,  this  Mortgage or the other Loan
Documents.

     26. Counsel Fees. Reserved.

     27.  Further  Assurances.  Mortgagor  will execute and deliver such further
instruments  and perform  such further  acts as may be  reasonably  requested by
Mortgagee  from time to time to confirm the priority of the lien created by this
Mortgage  on any  property,  rights or  interest  encumbered  or  intended to be
encumbered by the lien of this Mortgage or the other Loan Documents.

     28. Future Advances. Without limiting any other provisions of this Mortgage
and pursuant to the provision of New Jersey  statutes  46:9-8.1 and 9-8.2,  this
Mortgage shall also secure additional loans and other future advances  hereafter
made by Mortgagee to Mortgagor, or for the benefit of Mortgagor, but in no event
shall the total outstanding  indebtedness secured hereby at any such time exceed
(a) twice the amount of the original  principal  indebtedness  of the Notes plus
(b) all  accrued  and  unpaid  interest.  Each such  additional  loans or future
advance  shall be evidenced  by a Notes or other  evidence of  indebtedness  and
shall be  automatically  secured  hereby  without the  necessity of the Notes or
other  evidence of  indebtedness  identifying  such  additional  loans or future
advance as part of the  indebtedness  secured by this  Mortgage.  Nothing herein
contained  shall imply any  obligation on the part of Mortgagee to make any such
additional loans or future advance(s).

                                       15


     29.  Representations  and Warranties.  Mortgagor  represents,  warrants and

          (h) The improvements located in the Mortgaged Property do not encroach
upon any building line, setback line, side yard line, or any recorded or visible

the title policy insuring the lien of this Mortgage.

          (i) If any construction has occurred at the Mortgaged  Property within

          (l) Mortgagor is not a "foreign person" within the meaning of Sections
1445 or 7701 of the Internal Revenue Code.

     30.  Severability and Savings Clauses. If any provision of this Mortgage is
held to be invalid or  unenforceable by a Court of competent  jurisdiction,  the
other  provisions  of this  Mortgage  shall  remain in full force and effect and
