            (d) That  Mortgagor has no knowledge of any violations or notices of
violations  of any  requirements  for  which  waiver(s)  of same  have  not been
obtained.






            (e) If Mortgagor  (or any general  partner of Mortgagor if Mortgagor

intended  purposes are  presently  available to the Premises (or the  boundaries
thereof if this Mortgage is executed in conjunction  with a  construction  loan)
through dedicated public rights of way or through  perpetual private  easements,

binding and enforceable first lien, including, but not limited to, water supply,
storm and sanitary sewer, gas, electric and telephone facilities, and drainage.

            (g) That neither the Mortgaged  Property nor any portion  thereof is

force and effect so long as the possibility of such liability,  claims or losses
exists.

to  Mortgagee  are true and  correct  in all  respects,  have been  prepared  in

or  type  whatsoever  (whether  oral  or  written,  formal  or  informal),   the
performance  of which by the other  party  thereto  could give rise to a lien or
encumbrance on the Mortgaged  Property,  except for contracts (all of which have
been disclosed in writing to Mortgagee)  made by Mortgagor with parties who have
executed and delivered lien waivers to Mortgagor,  and which,  in the opinion of
Mortgagee's counsel, will not create rights in existing or future lien claimants
which may be superior to the lien of the Mortgage.

the Note or in any modification, renewal or extension of the Note.

      3. INSURANCE. At all times that the Note is outstanding, including without

any monies secured by this Mortgage, or, may be paid over, wholly or in part, to
the  Mortgagor  for the repair of the  Improvements  or for any other purpose or
object  satisfactory  to the Mortgagee.  Mortgagor shall deliver to Mortgagee at
least thirty (30) days prior to the expiration  date of any insurance  coverages
required  hereunder,  a  certificate  reciting  that  there is in full force and
effect, with a term covering at least the next succeeding year, insurance in the
amounts and of the types required hereunder.

      5. ALTERATIONS.  No Improvements shall be structurally altered, removed or
demolished  without the prior written  consent of Mortgagee  which consent shall
not be unreasonably withheld.

      6.  APPOINTMENT  OF RECEIVER.  Mortgagee  in any action to foreclose  this
Mortgage shall be entitled,  without notice and as a matter of right and without
regard to the  adequacy of any security of the  indebtedness  or the solvency of
Mortgagor, upon application to any court having jurisdiction, to the appointment
of a receiver of the rents, income and profits of the Mortgaged Property.

            If an Event of  Default  (hereinbelow  defined)  occurs  under  this
Mortgage,  as a matter  of right  and  without  regard  to the  adequacy  of any
security  for the Note,  the  Mortgagor,  upon  demand of the  Mortgagee,  shall
surrender  the  possession  of,  and it shall be lawful for  Mortgagee,  by such
officer or agent as it may appoint,  to take  possession,  of all or any part of
the  Mortgaged  Property  together with the books,  papers,  and accounts of the
Mortgagor pertaining thereto, and to hold, operate and manage the same, and from
time to time to make all needed repairs and improvements as Mortgagee shall deem
wise;  and,  if  Mortgagee   deems  it  necessary  or  desirable,   to  complete
construction  and  equipping  of any  Improvements  and in the  course  of  such
construction  or  equipping  to make  such  changes  to the  same as it may deem
desirable; and Mortgagee may sell the Mortgaged Property or any part thereof, or
institute  proceedings  for the complete or partial  foreclosure  of the lien of
this  Mortgage  on the  Mortgaged  Property,  or lease the  Premises or any part
thereof  in the name and for the  account  of the  Mortgagor  or  Mortgagee  and
collect, receive and sequester the rents, revenues,  earnings,  income, products
and  profits  therefrom,  and out of the  same  and any  other  monies  received
hereunder  pay or provide for the payment of, all proper  costs and  expenses of
taking,  holding,  leasing,  selling and managing the same, including reasonable
compensation to Mortgagee,  its agents and counsel, and any charges of Mortgagee
hereunder,  and any taxes and other  charges  prior to the lien of this Mortgage
which Mortgagee may deem it wise to pay.






      7.  PAYMENT OF TAXES.  Mortgagor  will pay all taxes,  assessments,  sewer
rents or water  rates or sums due under  any  payment  in lieu of tax  agreement
("Pilot  Agreement") and in default thereof,  Mortgagee may pay the same. In the
event that  Mortgagee  shall pay any such tax,  assessment,  sewer rent or water
rate,  Mortgagee shall have the right, among other rights, to declare the amount
so paid with interest thereon  immediately due and payable,  and upon default of
Mortgagor in paying any such amount with interest thereon,  Mortgagee shall have
the right to foreclose for such amount  subject to the  continuing  lien of this
Mortgage for the balance of the mortgage indebtedness not then due.

                  In the event that the Mortgagor should fail to pay any sum the
Mortgagor  has agreed to pay pursuant to this covenant for a period in excess of
sixty  (60) days after the same is due and  payable,  in  addition  to any other
remedies available to the Mortgagee hereunder, the Mortgagee may, at its option,
require that the  Mortgagor  deposit with the  Mortgagee,  monthly,  one-twelfth
(1/12th)  of the annual  charges for taxes and any other sums the  Mortgagor  is
obligated to pay pursuant to this  covenant  and the  Mortgagor  shall make such
deposits  with the  Mortgagee.  The  Mortgagor  shall  simultaneously  therewith
deposit  with the  Mortgagee  a sum of money  which  together  with the  monthly
installments  aforementioned  will be  sufficient  to make  payment  of all sums
required to be paid hereunder at least thirty (30) days prior to the due date of
such payments, it being understood that the Mortgagee shall calculate the amount
of such  deposits and notify the  Mortgagor  of the sum due.  Should an Event of
Default  (hereinbelow  defined)  occur,  the funds  deposited with the Mortgagee
pursuant  to this  provision  may be applied in payment of the charges for which
said funds shall have been deposited or to the payment of any other sums secured
by this Mortgage as the Mortgagee sees fit.

      8.  PAYMENT  OF  MORTGAGE  TAXES.  Mortgagor  shall pay all taxes  imposed
pursuant to Article 11 of the Tax Law or any other statute, order or regulation,
whether said tax is imposed at the time of recording or subsequent thereto. This
obligation shall survive the satisfaction or other termination of this Mortgage.
Mortgagee shall pay the tax imposed by Section 253 1-a(a), if applicable, if the
Mortgaged  Property  consists  of real  property  principally  improved or to be
improved by one or more structures containing in the aggregate not more than six
residential   units,   each  dwelling  unit  having  its  own  separate  cooking
facilities.

      9. STATEMENT OF AMOUNT DUE.  Mortgagor,  within five (5) days upon request
in person or within  fifteen  (15) days upon  request  by mail,  will  furnish a
written  statement  duly  acknowledged  of the amount due on this  Mortgage  and
whether any offsets or defenses exist against the said indebtedness.

      10. NOTICES. Any notices required or permitted to be given hereunder shall
be: (i)  personally  delivered or (ii) given by  registered  or certified  mail,
postage  prepaid,  return  receipt  requested,  or (iii)  forwarded by overnight
courier  service,  in each instance  addressed to the addresses set forth at the
head of this Mortgage, or such other addresses as the parties may for themselves
designate  in writing as provided  herein for the purpose of  receiving  notices
hereunder.  All notices  shall be in writing and shall be deemed  given,  in the
case of notice by personal  delivery,  upon actual delivery,  and in the case of
appropriate mail or courier  service,  upon deposit with the U.S. Postal Service
or delivery to the courier service.






      11.  WARRANTY  OF TITLE.  Mortgagor  warrants  the title to the  Premises,
Improvements and Chattels.

      12. SALE IN ONE PARCEL. In case of a sale, the Premises may be sold in one
parcel together with the Improvements and Chattels.  Should the Premises consist
of more than one parcel,  in the event of a foreclosure  of this Mortgage or any
mortgage at any time  consolidated  with this  Mortgage,  Mortgagor  agrees that
Mortgagee shall be entitled to a judgment directing the referee appointed in the
foreclosure  proceeding to sell all of the parcels  constituting the Premises at
one  foreclosure  sale,  either as a group or separately  and that the Mortgagor
expressly  waives  any right  that it may now have or  hereafter  acquire to (i)
request or require  that the  parcels be sold  separately  or (ii)  request,  if
Mortgagee has elected to sell parcels separately,  that there be a determination
of any  deficiency  amount after any such separate  sale or otherwise  require a
calculation of whether said parcel or parcels  separately sold were conveyed for
their "fair market value".

      13.  NEGATIVE  COVENANTS.  Mortgagor will not (i) execute an assignment of
the rents,  income or profits,  or any part thereof from the Mortgaged  Property
except to Mortgagee,  or (ii) except where the tenant is in default  thereunder,
terminate  or  consent  to the  cancellation  or  surrender  of any lease of the
Premises or Improvements or of any part thereof, now existing or hereafter to be
made,  having an unexpired term of two (2) years or more,  except that any lease
may be canceled  provided  that  promptly  after the  cancellation  or surrender
thereof a new lease is entered into with a new tenant having a credit  standing,
in the  judgment of the  Mortgagee,  at least  equivalent  to that of the tenant
whose lease was canceled,  on substantially  the same terms as the terminated or
canceled  lease,  or modify any such lease so as to shorten the  unexpired  term
thereof or so as to  decrease  the amount of the rents  payable  thereunder,  or
(iii) accept  prepayments  of any sums to become due under such  leases,  except
prepayments of rent for more than one (1) month in advance or prepayments in the
nature of security for the  performance of the tenants  thereunder,  (iv) in any
other manner impair the value of the Mortgaged  Property or the security of this
Mortgage  or (v)  further  encumber,  alienate,  hypothecate,  grant a  security
interest in or grant any other  interest  whatsoever in the Mortgaged  Property.
Restrictions (ii) and (iii) are made with reference to Section 291-f of the Real
Property Law and actions in violation of those  provisions  shall be voidable at
the option of the Mortgagee. No rent reserved under any lease of the Premises or
Improvements  has been  assigned  or  anticipated,  and no rent  for any  period
subsequent  to the date  hereof  has been  collected  in advance of the due date
thereof. Mortgagor will not execute any lease of all or a substantial portion of
the  Premises  or  Improvements  except  for  actual  occupancy  by  the  tenant
thereunder,  and will at all times promptly and faithfully  perform, or cause to
be performed,  all of the covenants,  conditions and agreements contained in all
leases of the Premises or Improvements now or hereafter existing, on the part of
the landlord  thereunder  to be kept and  performed and will at all times do all
things  necessary  to compel  performance  by the tenant under each lease of all
obligations, covenants and agreements by such tenant to be performed thereunder.
If any of such leases provide for the giving by the tenant of certificates  with
respect to the status of such  leases,  Mortgagor  shall  exercise  its right to
request  such  certificates  within  five (5)  days of any  demand  therefor  by
Mortgagee. Mortgagor shall furnish to Mortgagee, upon request of Mortgagee to do
so, a written  statement  containing the names of all tenants of the Premises or
Improvements,  the terms of their respective  leases, the space occupied and the
rentals payable thereunder.




      14. APPRAISAL. For the purposes of this Section, the following terms shall

compliance with the financial covenants set forth in that certain Loan Agreement

that,  to the best of his/her  knowledge,  no  default  or Event of Default  has
occurred  or is  occurring  or, in the event a default or Event of  Default  has
occurred or is  occurring,  then how same will be cured within thirty (30) days.
For  purposes  of the Loan  covenants,  all  accounting  terms  shall be defined
according to generally accepted accounting principles (GAAP) definitions;





            (f) An annual  budget for the  upcoming  year to  include  projected

accountant, if requested by Mortgagee, and shall cover such period or periods as

notice be given, said indebtedness  shall become due, payable and collectible at
the expiration of said thirty (30) days.

      18.         INTENTIONALLY OMITTED.






      19. PROVISIONS REGARDING USE OF MORTGAGED PROPERTY. Mortgagor warrants and
represents that:

            (a)  Mortgagor is not  responsible  for any action or omission,  and
does not know of any action or omission by any prior owner, that would cause the
Mortgaged  Property to be subject to  forfeiture  pursuant  to any law,  rule or
regulation (a "Forfeiture").

            (b) The  Mortgaged  Property has not been acquired with any proceeds
from a transaction or an activity that would cause the Mortgaged  Property to be
subject to Forfeiture.

            Mortgagor covenants that Mortgagor will not use, and will not permit
any third  party to use,  the  Mortgaged  Property  or any  portion  thereof  or
interest  therein  for any purpose or  activity  that would  cause a  Forfeiture
thereof.

      20. ACTIONS AND  PROCEEDINGS.  If any action or proceeding be commenced to
which  action or  proceeding  Mortgagee  is made a party and in which it becomes
necessary  in the  opinion  of  Mortgagee  to defend or uphold  the lien of this
Mortgage,  all sums paid by  Mortgagee  for the  expense  of any  litigation  to
prosecute  and defend the rights and lien  created by this  Mortgage,  including
reasonable  counsel fees,  costs and allowances,  shall,  together with interest
thereon be a lien on the  Mortgaged  Property  and secured by this  Mortgage and
shall be  collectible in like manner as said  indebtedness  and shall be paid by
Mortgagor on demand.

      21.  SECURITY  INTEREST UNDER THE UNIFORM  COMMERCIAL  CODE.  Mortgagee is
authorized to sign as the agent of Mortgagor  such agreement in addition to this
Mortgage as  Mortgagee  at any time may deem  necessary  or proper or require to
grant to  Mortgagee a perfected  security  interest in the  Chattels.  Mortgagor
hereby  authorizes  Mortgagee  to file  financing  statements  (as such  term is
defined in said Uniform  Commercial  Code) with respect to the Chattels,  at any
time, without the signature of Mortgagor.  Mortgagor will,  however, at any time
upon request of Mortgagee,  sign such financing  statements.  Mortgagor will pay
all filing fees for the filing of such financing statements and for the refiling
thereof at the times  required,  in the opinion of  Mortgagee,  by said  Uniform
Commercial  Code.  If the  lien of this  Mortgage  be  subject  to any  security
agreement  covering the  Chattels,  then in the event of any default  under this
Mortgage,  all the right,  title and interest of Mortgagor in and to any and all
of the Chattels is hereby  assigned to  Mortgagee,  together with the benefit of
any  deposits or payments  now or  hereafter  made  thereof by  Mortgagor or the
predecessors or successors in title of Mortgagor in the Mortgaged Property.






      22.  CONDEMNATION.  Any and all awards  heretofore  and hereafter  made to
Mortgagor  and  all  subsequent   owners  of  the  Mortgaged   Property  by  any
governmental or other lawful authorities for the taking by eminent domain of the
whole or any part of the Mortgaged  Property or any easement therein,  including
any  awards  for any  changes  of grade  of  streets,  are  hereby  assigned  to
Mortgagee,  who is hereby  authorized to collect and receive the proceeds of any
such awards from such  authorities,  to give proper  receipts  and  acquittances
therefor and to apply the same toward the payment of the amount owing on account
of this Mortgage and said indebtedness, notwithstanding the fact that the amount
owing thereon may not then be due and payable provided,  however,  if such award
is less than  $100,000 it shall be paid over to the  Mortgagor for the repair if
any damages  resulting  from such taking;  and  Mortgagor  hereby  covenants and
agrees,  upon request,  to make, execute and deliver any and all assignments and
other  instruments  sufficient for the purpose of assigning the aforesaid awards
to Mortgagee free,  clear and discharged of any and all encumbrances of any kind
or nature whatsoever.  Mortgagor shall continue to make all payments required by
the Note until any such award shall have been actually received by Mortgagee and
any reduction in said  indebtedness  resulting from the application by Mortgagee
of such award shall be deemed to take effect only on the date of such receipt.

      Notwithstanding  the foregoing,  if any one or more of the portions of the
Mortgaged  Property  described in subparagraphs  (a), (b) and (c) below shall be
damaged or taken through condemnation,  either temporarily or permanently,  then
the entire balance due under the Note and any other Loan Documents shall, at the
option of Mortgagee, become immediately due and payable:

            (a)   Any portion or portions of the  Improvements  or the support
or  foundation of any portion or portions of the Improvements; or

            (b) Ten (10%) percent or more of any parking area; or

            (c) Any portion or portions of the Premises  which,  when so damaged
or taken, would result either in (i) an impairment of access to the Improvements
from the publicly  dedicated  rights of way now adjoining the Premises,  or (ii)
the failure of the  Improvements  to comply with any  building  code,  zoning or
other  governmental  laws or regulations,  lease or other agreement to which the
Mortgaged Property is subject.

      Mortgagor authorizes Mortgagee, at Mortgagee's option, as attorney in fact
for  Mortgagor,  to  commence,   appear  in  and  prosecute  in  Mortgagor's  or
Mortgagee's name, any action or proceeding relating to any condemnation or other
taking  of the  Mortgaged  Property  and to settle  or  compromise  any claim in
connection with such condemnation or other taking.

      23.  TITLE  TO  MORTGAGED  PROPERTY.  Mortgagor  is now the  owner  of the
Mortgaged Property upon which this Mortgage is a valid first lien for the amount
above  specified,  with  interest  thereon at the rate set forth in the Note and
there are no defenses or offsets to this Mortgage or to the said indebtedness.






      24. LEASES OF THE MORTGAGED PROPERTY.  Mortgagor will not lease all or any
portion of the Mortgaged  Property or amend,  modify or terminate (except to the
extent permitted under paragraph 13(ii) hereof) any now existing or future lease
of the  Mortgaged  Property  without  the prior  written  consent of  Mortgagee.
Notwithstanding  the foregoing,  all leases  covering more than fifteen  percent
(15%) of the gross  leasable  area of the  Mortgaged  Property (if the Mortgaged
Property is improved  rental  property)  must require the tenant  thereunder  to
provide Mortgagee with annual financial statements of the tenant certified to by
an independent certified public accountant.  Mortgagor,  at Mortgagee's request,
shall furnish Mortgagee with executed copies of all leases hereafter made of all
or any part of the Mortgaged  Property,  and all leases now or hereafter entered
into will be in form and substance  subject to the approval of  Mortgagee.  Upon
Mortgagee's request,  Mortgagor shall make a separate and distinct assignment to
Mortgagee,  as additional  security,  of all leases hereafter made a part of the
Mortgaged Property.

      25. TRANSFER OF MORTGAGED PROPERTY.  In the event that (a) any entity then
having a lesser credit rating than Mortgagor shall acquire beneficial  ownership
of a majority interest in the voting stock of Mortgagor, (b) the Mortgagor shall
merge with such an entity and shall not be the surviving corporation, or (c) the
Mortgaged  Property or a part thereof,  while this Mortgage  shall remain a lien
thereon,  shall be sold, conveyed or transferred by deed, any other voluntary or
involuntary  act or by  operation of law or  otherwise,  the full balance of the
indebtedness  then remaining unpaid,  with interest,  shall at the option of the
Mortgagee,  or its assigns,  be  immediately  due and payable  without notice or
demand  unless the prior written  consent of the Mortgagee to such  acquisition,
merger, or sale,  conveyance or transfer shall have been obtained. A mortgage of
the Mortgaged Property to any mortgagee other than the Mortgagee shall be deemed
a conveyance for the purpose of this Section.

      26. ACCESS. Mortgagee, by its employees or agents, shall at all times have
the right to enter upon the Mortgaged Property during reasonable  business hours
for the purpose of examining and inspecting the same.

      27. REAL  PROPERTY  LAW. All  covenants  hereof,  which are in addition to
those set forth in Sections  254 and 291-f of the Real  Property  Law,  shall be
construed as affording to Mortgagee rights  additional to, and not exclusive of,
the rights conferred under the provisions of said Sections 254 and 291-f.

      28. PERFORMANCE OF MORTGAGOR'S COVENANTS BY MORTGAGEE. In the event of any
default in the  performance  of any of the  covenants,  terms,  or provisions of
Mortgagor under this Mortgage,  which default is not cured within any applicable
cure period, Mortgagee may, at the option of Mortgagee, perform the same and the
cost  thereof,  with  interest,  shall  immediately  be due  from  Mortgagor  to
Mortgagee and secured by this Mortgage.

      29.  REMEDIES NOT EXCLUSIVE.  Mortgagee  shall have the right from time to
time, to take action to recover any amounts of past due  principal  indebtedness
and interest  thereon,  or any installment of either, or any other sums required
to be paid under the  covenants,  terms and  provisions  of this Mortgage or the
Note, as the same become due, whether or not the principal indebtedness secured,
or any other sums secured by the Note or this Mortgage shall be due, and without
prejudice  to  the  right  of  Mortgagee   thereafter  to  bring  an  action  of
foreclosure,  or any other action, for default or defaults by Mortgagor existing
at the time such earlier action was commenced.






      30.  ADDITIONAL ACTS AND DOCUMENTS.  Mortgagor  covenants that it will do,
execute, acknowledge, deliver, file and/or record, or cause to be recorded every
and all such further acts, deeds, conveyances,  advances,  mortgages,  transfers
and  assurances,  in law as  Mortgagee  shall  require for the better  assuring,
conveying, transferring, mortgaging, assigning and confirming unto Mortgagee all
and singular the Mortgaged Property.

      31.  REMEDIES  CUMULATIVE.  The rights and  remedies  herein  afforded  to
Mortgagee  shall be  cumulative  and  supplementary  to and not exclusive of any
other rights and remedies afforded the holder of this Mortgage and the Note.

      32. SUCCESSORS.  All of the provisions of this Mortgage shall inure to the
benefit of Mortgagee and of any subsequent  holder of this Mortgage and shall be
binding upon Mortgagor and each subsequent owner of the Mortgaged Property.

      33. EFFECT OF RELEASES. Mortgagee, without notice, may release any part of
the  security  described  herein,  or  any  person  or  entity  liable  for  any
indebtedness  secured  hereby  without in any way affecting the lien hereof upon
any part of the security not  expressly  released,  and may agree with any party
obligated on said indebtedness or having any interest in the security  described
herein to extend  the time for  payment  of any part or all of the  indebtedness
secured  hereby.  Such agreement shall not in any way release or impair the lien
hereof,  but shall  extend the lien  hereof as against  the title of all parties
having any interest in said  security,  which  interest is subject to said lien,
and no such release or agreement shall release any person or entity obligated to
pay any indebtedness secured hereby.






      34.  WAIVERS.   Any  failure  by  Mortgagee  to  insist  upon  the  strict
performance by Mortgagor of any of the  covenants,  terms and provisions of this
Mortgage shall not be deemed to be a waiver of any of the  covenants,  terms and
provisions of this Mortgage,  and Mortgagee,  notwithstanding  any such failure,
shall  have the  right  thereafter  to insist  upon the  strict  performance  by
Mortgagor of any and all of the covenants, terms and provisions of this Mortgage
to be performed by Mortgagor.  Neither  Mortgagor nor any other person or entity
now or  hereafter  obligated  for the  payment  of the whole or any part of said
indebtedness  shall be relieved of such  obligation by reason of (i) the failure
of Mortgagee to comply with any request of Mortgagor,  or of any other person or
entity so  obligated,  (ii) the failure of Mortgagee to take action to foreclose
this Mortgage or otherwise enforce any of the covenants, terms and provisions of
this Mortgage or the Note, (iii) the release,  regardless of  consideration,  of
the whole or any part of the security held for payment of said  indebtedness  or
(iv) any agreement or stipulation  between any subsequent owner or owners of the
Mortgaged Property and Mortgagee  modifying the covenants,  terms and provisions
of this  Mortgage  or the Note  without  first  having  obtained  the consent of
Mortgagor or such other person or entity. In the last mentioned event, Mortgagor
and all such  other  persons  or  entities  shall  continue  liable to make such
payments  according  to the  terms  and  provisions  of any  such  agreement  or
extension or modification unless expressly released and discharged in writing by
Mortgagee.  Mortgagee may release, regardless of consideration,  any part of the
security held for payment of said indebtedness  without,  as to the remainder of
the security, in any way impairing or affecting the lien of this Mortgage or the
priority of such lien over any  subordinate  lien.  Mortgagee may resort for the
payment of said indebtedness to any other security therefor held by Mortgagee in
such order and manner as Mortgagee may elect.

      35. INTEREST ON ADVANCES.  Wherever, under the provisions of this Mortgage
or by law,  Mortgagee  is entitled  to  interest  on  advances  made or expenses
incurred, such interest shall be computed at a rate per annum which shall be the
interest rate payable under the Note.

      36.  MORTGAGEE NOT OBLIGATED.  Nothing herein contained shall be construed
as making the payment of any insurance premiums, taxes or assessments obligatory
upon Mortgagee,  although  Mortgagee may pay same, or as making Mortgagee liable
in any way for loss,  damage or injury,  resulting  from the  non-payment of any
such insurance premiums, taxes or assessments.

      37. LIEN LAW.  Mortgagor  will, in compliance  with Section 13 of the Lien
Law,  receive the advances  secured by this  Mortgage and will hold the right to
receive  such  advances  as a trust fund to be applied  first for the purpose of
paying the cost of the  improvement and will apply the same first to the payment
of the cost of the  improvement  before  using any part of the total of the same
for any other purpose.

      38.   ENVIRONMENTAL WARRANTIES AND COVENANTS.

            (a) Warranties.  Mortgagor makes the following  representations  and
warranties:  (i) Mortgagor (or the present owner of the Mortgaged  Property,  if

and local laws and regulations, including, without limitation, those relating to
toxic and hazardous  substances  and other  environmental  matters (the "Laws"),
(ii) no  portion  of the  Mortgaged  Property  is being  used or, to the best of
Mortgagor's  knowledge,  has been used at any previous  time,  for the disposal,
storage,  treatment,  processing  or other  handling of any  hazardous  or toxic
substances,  in a manner not in compliance with the Laws, (iii) the soil and any
surface  water and ground water which are a part of the  Mortgaged  Property are
free from any solid wastes,  toxic or hazardous substance or contaminant and any
discharge of sewage or effluent; and (iv) neither the federal government nor the

governmental  or quasi  governmental  entity  has filed a lien on the  Mortgaged
Property,  nor are there any governmental,  judicial or  administrative  actions
with respect to environmental matters pending, or to the best of the Mortgagor's
knowledge, threatened, which involve the Mortgaged Property.

            (b) Inspection.  In the event Mortgagee  reasonably believes that an
environmental  problem may exist,  Mortgagor agrees that Mortgagee or its agents
or  representatives  may,  at any  reasonable  time and at  Mortgagor's  expense
inspect  Mortgagor's  books and records and inspect and conduct any tests on the
Mortgaged  Property  including taking soil samples in order to determine whether
Mortgagor is in continuing compliance with the Laws.






            (c) Agreement to Comply. If any environmental contamination is found
on the Mortgaged  Property for which any removal or remedial  action is required
pursuant to Law,  ordinance,  order,  rule,  regulation or governmental  action,

remedial action promptly and to Mortgagee's satisfaction.

            (d) Indemnification.  Mortgagor agrees to defend, indemnify and hold

reasonable  attorney and consultant  fees,  investigations  and laboratory fees,
court costs and litigation expenses of whatever kind or nature known or unknown,
contingent or  otherwise)  arising out of or in any way related to: (i) the past
or present  disposal,  release or  threatened  release of any hazardous or toxic
substances  on the  Mortgaged  Property;  (ii) any  personal  injury  (including
wrongful death or property damage,  real or personal)  arising out of or related
to such hazardous or toxic substances;  (iii) any lawsuit brought or threatened,
settlement reached or government order given relating to such hazardous or toxic
substances;   and/or  (iv)  any  violation  of  any  law,   order,   regulation,
requirement,  or  demand  of  any  government  authority,  or  any  policies  or
requirements  of  Mortgagee,  which are based upon or in any way related to such
hazardous or toxic substances.

            (e) Other Sites. Mortgagor knows of no on-site or off-site locations
where  hazardous or toxic  substances  from the operation of any  Improvement or
otherwise have been stored, treated, recycled or disposed of.

            (f) Leases.  Mortgagor agrees not to lease or permit the sublease of
the Mortgaged  Property to a tenant or subtenant whose  operations may result in
contamination of the Mortgaged Property with hazardous or toxic substances.

            (g)  Non-Operation  by Mortgagee.  Mortgagor  acknowledges  that any
action Mortgagee takes under this Mortgage shall be taken to protect Mortgagee's
security  interest only;  Mortgagee does not hereby intend to be involved in the
operations of the Mortgagor.

            (h)  Compliance  Determinations.  Mortgagor  acknowledges  that  any
determinations  Mortgagee  makes under this Section  regarding  compliance  with
environmental  laws  shall  be made  for  Mortgagee's  benefit  only and are not
intended to be relied upon by any other party.

            (i) Survival of Conditions.  The provisions of this Section shall be
in addition  to any other  obligations  and  liabilities  Mortgagor  may have to
Mortgagee at common law, and shall survive the transactions contemplated herein.

            (j) Other  Insurance.  Mortgagor  shall carry adequate  insurance to
fulfill Mortgagor's obligations under this Section if required by law.






            (k)  Definitions.  The term  "hazardous  substance"  shall  include,
without limit, any substance or material  defined in 42 U.S.C.  Section 9601 (as
the  same  may  be  amended  from  time  to  time),   the  Hazardous   Materials
Transportation  Act (as amended  from to time),  and the New York  Environmental
Conservation  Law or the Resource  Conservation And Recovery Act (as each may be
amended  from  time to time)  and in any  regulations  adopted  or  publications
promulgated pursuant to any of the foregoing.

      39  EVENTS OF DEFAULT.  The whole of the principal sum of the indebtedness
secured  hereby  and  interest  thereon,  and all  other  sums  due and  payable
hereunder  shall become due, at the option of  Mortgagee,  if one or more of the
following events (an "Event of Default") shall happen:

            (a)   The occurrence of an "Event of Default" under the Note; or

consent of Mortgagee;  or the removal,  demolition or destruction in whole or in
part, of any Chattels without replacing the same with Chattels at least equal in
quality and  condition to those  replaced,  free from any  security  interest or
other encumbrance thereon and free from any reservation of title thereto; or the
commission of any waste in respect to the Mortgaged Property; or

            (d) Failure of Mortgagor to pay within thirty (30) days after notice

of this Mortgage and the other Loan Documents, the same shall be null and void.

            (a) Mortgagor shall  indemnify,  defend and hold Mortgagee  harmless
against: (i) any and all claims for brokerage,  leasing, finders or similar fees
which may be made  relating to the  Mortgaged  Property or the loan which is the
subject  of the  Note,  and (ii)  against  any and all  liability,  obligations,
losses,  damages,  penalties,   claims,  actions,  suits,  costs,  and  expenses
(including its reasonable  attorneys' fees,  together with reasonable  appellate
counsel  fees,  if any) of  whatever  kind or nature  which may be imposed on or
incurred by  Mortgagee  at any time  pursuant  either to a judgment or decree or
other order entered into by a court or administrative  agency or to a settlement
reasonably approved by Mortgagor,  which judgment,  decree,  order or settlement
relates in any way to or arises out of the offer, sale or lease of the Mortgaged
Property  and/or the ownership,  use,  occupation or operation of any portion of
the Mortgaged Property.






            (b)  If  Mortgagee  is  made a  party  defendant  to any  litigation
concerning  the loan  which is the  subject  of the  Note,  this  Mortgage,  the
Mortgaged  Property,  or any  part  thereof,  or any  interest  therein,  or the
occupancy  thereof,  then Mortgagor shall  indemnify,  defend and hold Mortgagee
harmless from all liability by reason of said litigation,  including  reasonable
attorneys'  fees (together with reasonable  appellate  counsel fees, if any) and
expenses  incurred by Mortgagee in any such litigation,  whether or not any such
litigation is prosecuted to judgment.  If Mortgagee  commences an action against

reasonable  appellate  counsel  fees,  if any) and  expenses.  The right to such
attorneys  fees (together with  reasonable  appellate  counsel fees, if any) 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
Mortgagor  breaches any term of this Mortgage,  Mortgagee may employ an attorney
or  attorneys  to  protect  its  rights  hereunder,  and in the  event  of  such
employment  following  any breach by  Mortgagor,  Mortgagor  shall pay Mortgagee
reasonable  attorneys' fees (together with reasonable appellate counsel fees, if
any) and expenses  incurred by  Mortgagee,  whether or not an action is actually
commenced against Mortgagor by reason of such breach.

            (c) A waiver of subrogation  shall be obtained by Mortgagor from its
property insurance carrier and, consequently, Mortgagor waives any and all right
to claim or recover  against  Mortgagee,  its  officers,  employees,  agents and
representatives,  for loss of or damage to Mortgagor,  the  Mortgaged  Property,
Mortgagor's  property or the property of others under  Mortgagor's  control from
any cause insured against or required to be insured against by the provisions of
this Mortgage.

            (d) All sums  payable by Mortgagor  hereunder  shall be paid without
notice  (except as may  otherwise  be provided  herein),  demand,  counterclaim,
set-off,  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 by
reason of: (i) any damage to or  destruction of or any  condemnation  or similar
taking of the Mortgaged  Property or any part thereof;  (ii) any  restriction or
prevention of or interference with any use of the Mortgaged Property or any part
thereof; (iii) any title defect or encumbrance or any eviction from the Premises
or the Improvements or any part thereof by title superior or otherwise; (iv) any
bankruptcy, insolvency,  reorganization,  composition,  adjustment, dissolution,
liquidation, or other like proceeding relating to Mortgagee, or any action taken
with respect to this Mortgage by any trustee or receiver of Mortgagee, or by any
court,  in such  proceeding;  (v) any claim which  Mortgagor has, or might have,
against  Mortgagee;  (vi) any  default or failure  on the part of  Mortgagee  to
perform or comply with any of the terms  hereof or of any other  agreement  with
Mortgagor;  or  (vii)  any  other  occurrence  whatsoever,  whether  similar  or
dissimilar  to the  foregoing,  whether or not  Mortgagor  shall have  notice or
knowledge of any of the foregoing.  Mortgagor waives all rights now or hereafter
conferred  by statute or  otherwise  to any  abatement,  suspension,  deferment,
diminution, or reduction of any sum secured hereby and payable by Mortgagor.

      49  WAIVER OF JURY TRIAL.  The Mortgagor  and the  Mortgagee  hereby waive
trial by jury in any  litigation  in any court with  respect  to, in  connection
with,  or  arising  out of this  Mortgage  or any other  Loan  Document,  or any
instrument  or  document  delivered  in  connection  with the loan  which is the
subject of the Note, or the validity, protection, interpretation,  collection or
enforcement  thereof,  or the  relationship  between  Mortgagor and Mortgagee as
borrower and lender, or any other claim or dispute howsoever arising between the
