Commercial  Code of the state in which the  Mortgaged  Property  is located  and
shall  additionally  include  whatever is received  upon the use,  lease,  sale,
exchange,  collection,  or other  utilization  or any  disposition of any of the
Mortgaged  Property,  voluntary  or  involuntary,   whether  cash  or  non-cash,
including  proceeds  of  insurance  and  condemnation  awards,  rental  or lease
payments,  accounts,  chattel paper,  instruments,  documents,  contract rights,

         TO HAVE AND TO HOLD the  Mortgaged  Property  unto the Mortgagee to and
for the use of the Mortgagee forever.

         1.3  Security  Agreement.  This  Mortgage is also a security  agreement
under the Uniform  Commercial Code of the state in which the Mortgaged  Property
is located.  Mortgagor  grants,  and  Mortgagee  shall have and may  enforce,  a
security  interest in all those  property  interests  included in the  Mortgaged
Property which may be "personal  property" to secure payment and  performance of
all  Obligations.  If the Mortgaged  Property is located in the  Commonwealth of
Pennsylvania,  this  Mortgage  is intended to be an  industrial  plant  mortgage
within the broadest  interpretation of the "industrial plant mortgage  doctrine"
under the laws of the  Commonwealth  of  Pennsylvania.  Mortgagor shall execute,
deliver, file and refile any financing statements,  continuation statements,  or
other  security  agreements  Mortgagee  may  require to confirm the lien of this
Mortgage with respect to such property. Mortgagor irrevocably appoints Mortgagee
attorney-in-fact for Mortgagor to execute, deliver and file such instruments.

         1.4  Assignment of Leases and Income.

              (a) This  Mortgage is also an absolute  assignment to Mortgagee of
all Leases and Income.  Mortgagor  hereby  assigns,  transfers  and sets over to
Mortgagee  all  Leases,  all income and all rights of  Mortgagor  to enforce the
Leases and collect the income.

              (b) Mortgagor  Irrevocably appoints Mortgagee the attorney-in-fact
of  Mortgagor  to enforce  the Leases  and  collect  the income and the sole and
exclusive agent of Mortgagor to agree to any  modification  of the Leases.  This
power is coupled with an interest and is therefore irrevocable . Mortgagor shall
notify any person which  Mortgagee may from time to time specify that the income
should be paid  directly to mortgagee  and that any  modification  of the Leases
must be approved by Mortgagee.

              (c) So long as  Mortgagor  is not in default in any respect  under
the Loan  Documents,  Mortgagor  shall have a license,  revocable at the will of
Mortgagee,  to  enforce  the  Leases  and  collect  the  income  subject  to any
applicable provisions contained in the Loan Documents.

              (d) All security deposits,  prepaid rent permitted to be collected
by Mortgagor,  if any (other than prepaid rent for the next succeeding  calendar
month),  and similar  payments  under any Lease shall be deposited in a separate
escrow  account  with  Mortgagee.   Mortgagor  shall  notify  Mortgagee  of  the
identification of the escrow account. Such sums shall be disbursed only upon the
prior  written  consent of Mortgagee  except such consent  shall not be required
when by law or by the terms of the Lease  Mortgagor  is  required  to, and does,
return such sums to the party entitled to same under the Lease.

          1.5 Open-End  Mortgage.  If the  Mortgaged  Property is located in the
Commonwealth of Pennsylvania, this is an Open-End Mortgage and shall be entitled
to all  benefits  as such  under 42 Pa.  C.S.A.  8143  (the  "Open-End  Mortgage
Statute").

              (a) If (i) this  Mortgage  secures a line of credit or other  loan
facility  pursuant to which  advances are made from time to time by Mortgagee to
Mortgagor,  and (ii)  Mortgagee  receives  written  notice  pursuant  to Section
8143(b) of the Open-End  Mortgage Statute from a holder of a lien or encumbrance
on the Mortgaged Property which is subordinate to the lien of the Mortgage, then
and  notwithstanding  any  provision  to the  contrary  contained  in  any  Loan
Document,  Mortgagor  agrees that Mortgagee shall not be responsible to make any
further  advances to Mortgagor (and Mortgagee is released from all liability for
failure to make such  advances) if Mortgagee  determines in its sole  discretion
that any such  advance  requested  by  Mortgagor  could  be  construed  to be an
unobligated advance under Section 8143(b) of the Open-End Mortgage Statute.

              (b) If (i) this  Mortgage  secures a loan facility the proceeds of
which  are  used to  provide  funds  to pay  toward  all or part of the  cost of
completing any erection,  construction,  alteration or repair of any part of the
Mortgaged  Property,  and (ii) Mortgagee  receives  written  notice  pursuant to
Section 8143(b) of the Open-End  Mortgage  Statute from a holder of a mechanic's
lien for labor  performed or to be  performed  or  materials  furnished or to be
furnished  for the erection,  construction,  alteration or repair of any part of
the Mortgaged  Property,  then and notwithstanding any provision to the contrary
contained in any Loan Document,  Mortgagor  agrees that Mortgagee shall have the
right to suspend  (until  such time as the lien is fully  released)  any further
advances to Mortgagor  (and Mortgagee is released from all liability for failure
to make such advances)  except advances which  Mortgagee  determines in its sole
discretion  are for the  purpose  of  paying  toward  all or part of the cost of
completing any erection,  construction,  alteration or repair of any part of the
Mortgaged Property the financing of which, in whole or in part, the Mortgage was
given to secure.

              (c) If Mortgagor should at any time elect to limit the Obligations
secured by this Mortgage  pursuant to Section  8143(c) of the Open-End  Mortgage
Statute,  Mortgagor  agrees  that  notice  of  such  election  shall  (i) not be
effective  unless and until it is served upon  Mortgagee in accordance  with the
requirements  of Section  8143(d) of the  Open-End  Mortgage  Statute  and fully
complies  with  the  requirements  for the  giving  of  notices  under  any Loan
Document;  (ii)  release  Mortgagee  from all  obligation  to make  any  further
advances  under the Loan  Documents  notwithstanding  anything  to the  contrary
contained  in such  notice  or the  Loan  Documents;  (iii)  constitute,  at the
election of Mortgagee,  an Event of Default under the Loan  Documents;  and (iv)
not be effective to limit  Mortgagor's  liability for payment and performance of
all Obligations  for which  Mortgagor is responsible  under this Mortgage or the
other  Loan  Documents   (including  all   reimbursement   and   indemnification
agreements)  whether such  Obligations  arise prior or subsequent to the date of
such notice.

         1.6  Purchase  Money  Mortgage.  If all or any part of the  Obligations
secured by this Mortgage  were used in whole or in part to fund the  acquisition
of all or any part of the Mortgaged  Property,  this Mortgage shall constitute a
purchase  money  mortgage  and shall be entitled  to all  benefits as such under
applicable laws of the state in which the Mortgaged Property is located.

                                   ARTICLE II
                                  TITLE MATTERS

         2.1  Warranty  of Title.  Until the  Obligations  are fully  satisfied,
Mortgagor represents, warrants and covenants that:

              (a) Mortgagor has good and marketable fee simple absolute title to
the  Mortgaged   Property  subject  only  to  those  exceptions  to  title  more
particularly  describe  in the title  commitment  issued  to, and  accepted  by,
Mortgagee  in  connection  with this  transaction  or  described  in Exhibit "B"
attached hereto,  (the "Permitted  Encumbrances") and Mortgagor shall defend the
validity,  priority and  enforceability of the lien of this Mortgage against the
claims  of  all  persons   excepting  only  those   claiming   under   Permitted
Encumbrances;

              (b) Mortgagor  has full power and lawful  authority to subject the
Mortgaged Property to the lien of this Mortgage;

              (c) The execution,  delivery and  performance of this Mortgage and
the other Loan Documents will not contravene any Legal  Requirements  (hereafter
defined) or any agreement,  document or instrument to which Mortgagor is a party
or by which Mortgagor or the Mortgaged Property is bound;

              (d) Mortgagor  shall make,  execute,  acknowledge  and deliver all
such further or other deeds,  documents,  instruments or assurances and cause to
be done all such  further  acts and  things  as may at any time be  required  by
Mortgagee to confirm and fully  protect the lien and priority of this  Mortgage;
and

              (e) Mortgagor shall make such payments,  when due, and perform all
obligations  as are required  under any  Permitted  Encumbrances  affecting  the
Mortgaged Property.

         2.2 No Transfer. Without the prior written consent of Mortgagee in each
instance, which consent may be given or withheld in Mortgagee's sole discretion,
Mortgagor will abstain from, and will not cause or permit, any transfer of title
to the  Mortgaged  Property or any part  thereof,  or any  transfer of ownership
interests  in  Mortgagor  (if  Mortgagor  is a  partnership,  joint  venture  or
corporation), voluntarily or by operation of law, nor shall Mortgagor enter into
any agreement or transaction to do or accomplish in form or substance any of the
foregoing.

         2.3 No Other  Financing or Liens.  Without the prior written consent of
Mortgagee  in  each  instance,  which  consent  may  be  given  or  withheld  in
Mortgagee's  sole  discretion,  Mortgagor shall not create or cause or permit to
exist any lien on the Mortgaged  Property  whether superior to or subject to the
lien of this Mortgage except the Permitted  Encumbrances (if any) and such other
liens or security  interests  as are  expressly  and  specifically  agreed to be
permitted upon the Mortgaged Property by Mortgagee under the Loan Documents.

         2.4 Leases.  Mortgagor represents and warrants that there are no Leases
affecting  the Mortgaged  Property  other than the Leases (if any) listed in the
schedule of Leases and Income  delivered by Mortgagor to Mortgagee in connection
with this  transaction.  Mortgagor  shall not enter into any Leases  without the
prior written consent of Mortgagee being obtained in each instance unless all of
the following are satisfied; (a) Mortgagee has approved a standard form of lease
and a then-current  schedule of minimum rental terms for the Mortgaged Property;
(b) the  Leases  are in  accordance  with the  pre-approved  lease form and rent

removal,  any such Fixtures  shall be replaced with other  Fixtures  which shall
have a value and utility at least equal to that of the replaced Fixtures and, by
such removal and  replacement,  Mortgagor shall be deemed to have subjected such
replacement Fixtures to the lien and priority of this Mortgage;

              (e) Make, install or permit to be made or installed, any additions
or  improvements  to the  Mortgaged  property  except in a good and  workmanlike
manner, free of mechanic's liens, in compliance with Legal Requirements,  and in
accordance with plans and specifications approved by Mortgagee; or

              (f) Make,  suffer or permit any nuisance to exist on the Mortgaged
Property or any portion thereof.

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

              (a) A fire or other casualty causing damage to the Mortgaged
Property,

              (b)  A  pending  or  threatened   condemnation  of  the  Mortgaged
Property,

              (c) A violation of a Legal  Requirement or other notice from or to
a Governmental Authority relating to the Mortgaged Property,

              (d)  Receipt or giving of any  notice of  default or  cancellation
under any Lease of all or a material portion of the Mortgaged Property,

              (e) Commencement of any litigation affecting the Mortgaged
Property,

              (f) Discovery,  discharge or release of any Hazardous Material for
which  Mortgagor is or may be  responsible  under any  Applicable  Environmental
Laws;

              (g) The existence of any event or condition  which presents a risk
of creating  material  liability in Mortgagor under ERISA (Public Law 93-406, as
amended); or

              (h) The occurrence of a default under, or the receipt or giving of
any notice under, any Permitted Encumbrance.

                                   ARTICLE IV
                               TAXES AND INSURANCE

         4.1  Real Estate Taxes and Assessments.

              (a) Mortgagor  shall pay when due and before interest or penalties
commence  to accrue  thereon,  all taxes,  assessments,  water and sewer  rents,
levies,  encumbrances  and all other  charges  or claims of any nature and kind,
whether public or private,  which may be assessed,  levied,  imposed,  suffered,
placed or filed at any time against the  Mortgaged  Property or any part thereof
or which by any  present or future law may have  priority  (either in lien or in
distribution  out of the  proceeds  of any sale) over the lien of this  Mortgage
(individually, an "imposition" and, collectively, "impositions").

              (b) Mortgagor shall produce to Mortgagee,  not later than the last
date any  such  imposition  is due and  payable  without  interest  or  penalty,
official receipts evidencing payment of such imposition.  If Mortgagor is not in
default  under  this  Mortgage  or any Loan  Document  and in good  faith and by
appropriate  legal action shall contest the validity or amount of any imposition
and shall have  established  a reserve for the payment  thereof in such form and
amount as Mortgagee may require  (including any interest and penalties which may
be payable in connection therewith), then Mortgagor shall not be required to pay
the imposition or to produce the receipts while the reserve is maintained and so
long as the contest operates to prevent collection, is maintained and prosecuted
with diligence,  and shall not have been terminated or discontinued adversely to
Mortgagor.

         4.2 Taxes on  Mortgagee.  If any  Governmental  Authority  shall  levy,
assess or charge any tax,  assessment  or  imposition  upon this Mortgage or any
other Loan Document  (including any requirement to have affixed to this Mortgage
any revenue, documentary or similar stamps) or upon the interest of Mortgagee in
the Mortgaged  Property by reason of this  Mortgage or any other Loan  Document,
Mortgagor  shall pay the same  directly  to such  Governmental  Authority  as an
imposition.  If Mortgagor is not legally  permitted to pay such imposition or to
reimburse  Mortgagee  for  amounts  advanced  on account of such  payment,  then
Mortgagee may declare the entire amount of the  Obligations  immediately due and
payable on demand.

         4.3 Corporate or Partnership Mortgagor.  If Mortgagor (or any successor
or grantee of Mortgagor) is a corporation or partnership, Mortgagor shall at all
times until the Obligations are satisfied in full:

              (a) Keep in effect and in good  standing its  existence and rights
as a corporation or partnership, as the case may, be under the laws of the state
of its  incorporation or constitution and its right to own property and transact
business in the state in which the Mortgaged Property is situated; and

              (b) File returns for all  federal,  state and local taxes with the
proper  Governmental  Authorities,  and pay,  when due and  payable  and  before
interest or  penalties  are due  thereon,  all taxes owing by  Mortgagor  to any
Governmental Authorities.

         4.4 Insurance  Coverages.  Until the Obligations  are fully  satisfied,
Mortgagor  shall maintain and keep in force the following  policies of insurance
with respect to the Mortgaged Property:

              (a) Insurance against loss or damage to the Mortgaged  Property by
fire and any of the risks  covered by  insurance of the type  commonly  known as
"all-risk  coverage,"  in an  amount  not less than the full  replacement  value
(evidenced by a "Replacement Cost Endorsement") of the Mortgaged Property;

              (b)  During  the  course  of any  construction  or  repair  of any
improvements on the Mortgaged Property, builder's completed value risk insurance
against "all risks of physical loss," including  collapse and transit  coverage,
during construction of such improvements, in non-reporting form;

              (c) Boiler and  machinery  insurance  (to the extent the Mortgaged
Property  includes  items  covered by such  insurance),  in such  amounts as are
reasonably satisfactory to Mortgagee;

              (d) Coverage against sprinkler leakage;

              (e) Vandalism and malicious mischief insurance;

              (f)  Comprehensive  public  liability  insurance on an "occurrence
basis"  against claims for personal  injury  including  bodily injury,  death or
property damage  occurring on or about the Mortgaged  Property and the adjoining
streets,  sidewalks and passageways,  with minimum  protection to a limit of not
less than  $1,000,000  (or such higher  amounts as are required  under any other
Loan  Document)  with  respect  to  personal  injury or death to any one or more
persons or damage to property;

              (g)  Worker's   compensation   insurance   (including   employer's
liability  insurance) for all employees of Mortgagor  engaged on or with respect
to the  Mortgaged  Property  in such  amount as is  reasonably  satisfactory  to
Mortgagee, or, if such limits are established by law, in such amounts;

              (h) Flood  insurance,  in accordance with National Flood Insurance
Act of 1968,  as amended by the Flood  Disaster  Protection  Act of 1973, if any
portion of the Mortgaged  Property lies within a flood hazard area designated by
the   Department   of  Housing   and  Urban   Development,   Federal   Insurance
Administration as a "Flood Hazard Area";

              (i) Business interruption and/or rental loss coverage for a period
equal to the  reasonable  period of time  required  to rebuild  and  restore the
Mortgaged Property upon the occurrence of a substantial destruction; and

              (j) Such other insurance, and in such amounts, as may from time to
time be required by Mortgagee.

         4.5 Policy  Requirements.  The insurance coverages required above shall
be insured under policies; (a) in form satisfactory to Mortgagee;  (b) issued by
companies  satisfactory  to Mortgagee;  (c) endorsed  with a standard  mortgagee
clause in favor of the Mortgagee  providing not less than thirty days' notice to
Mortgagee  of any  cancellation  or change in  coverage;  (d)  endorsed  to name
Mortgagee as additional insured and, subject only to Permitted  Encumbrances (if
any),  as loss  payee;  and (e) not  subject to  contribution  or  co-insurance.
Certificates  of Insurance,  addressed to Mortgagee,  evidencing  such insurance
coverage,  may be delivered to Mortgagee in lieu of the policies  therefor,  but
only if Mortgagor  provides to Mortgagee  copies of such policies.  Certificates
shall be  delivered to  Mortgagee  on or before the date of this  Mortgage  and,
thereafter,  at  least  thirty  (30)  days  before  expiration  of the  existing
policies.  If any insurance required under this Mortgage is cancelled,  expires,
becomes  void or voidable or  otherwise  becomes  unsatisfactory  to  Mortgagee,
Mortgagor  shall  place or cause to be placed  new  insurance  on the  Mortgaged
Property  reasonably  satisfactory  to  Mortgagee.  In the  event  of any  loss,
Mortgagee  may make  proof  of loss if not  made  promptly  by  Mortgagor.  Each
insurance  company  concerned is hereby  authorized and directed to make payment
under  such  insurance  including  return  of  unearned  premiums,  directly  to
Mortgagee instead of to Mortgagor and Mortgagee jointly,  and Mortgagor appoints
Mortgagee,  irrevocably,  as Mortgagor's  attorney-in-fact  to endorse any draft
therefor.

         4.6  Installments  for  Insurance,  Taxes  and Other  Charges.  Without
limiting  the effect of the other  provisions  of this  Article,  Mortgagor,  if
required  by  Mortgagee,  shall pay to  Mortgagee  monthly  an  amount  equal to
one-twelfth  (1/12) of the annual  amount of all  impositions  and  premiums for
insurance  policies  required  under  this  Article  plus  any  additional  sums
necessary  to pay, or  establish  adequate  reserves  for,  the payment of, such
premiums and  impositions  as and when due. The amount so paid shall be security
for the  premiums  and  impositions  and  shall be used in  payment  thereof  if
Mortgagor is not otherwise in default under this or any other Loan document.  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.  Upon the
occurrence  of an Event of Default  under this  Mortgage  or any Loan  Document,
Mortgagee  shall have the right,  at its  election,  to apply any amount so held
against the Obligations.  At Mortgagee's option, Mortgagee from time to time may
waive,  and after any such waiver may reinstate,  the provisions of this section
requiring installment payments.

                                    ARTICLE V
                             CASUALTY; CONDEMNATION

         5.1  Casualty.  If the  Mortgaged  Property is damaged by fire or other
casualty,  Mortgagor shall promptly repair and restore the same to its condition
prior to the  damage.  If,  and only for so long as,  the  following  terms  and
conditions are fully satisfied by Mortgagor,  Mortgagee shall release  insurance
proceeds for repair and restoration of the Mortgaged Property; otherwise, and to
the extent of any excess  proceeds,  Mortgagee shall have the right to apply the
proceeds toward reduction of the Obligations;

              (a) No default  under this or any other Loan  Document  shall have
occurred and be continuing uncured;

              (b)  Mortgagor  shall  have  delivered  evidence  satisfactory  to
Mortgagee that the Mortgaged  Property can be fully repaired and restored within
a period of time during which all payments  coming due under the Obligations are
fully covered by the proceeds of business  interruption or rental loss insurance
applicable to the loss or damage to the Mortgaged Property;

              (c) No  holder  of a  Permitted  Encumbrance  has a right to apply
insurance proceeds to the obligations secured by such Permitted  Encumbrance or,
if it does, the holder has waived in writing its right to do so;

              (d) No  lease is  cancellable  by the  lessee  on  account  of the
casualty or, if it is, the lessee has waived in writing its right to cancel;

              (e) The  work  is  performed  by a  reputable  general  contractor
satisfactory  to  Mortgagee  under a fixed  price or  guaranteed  maximum  price
contract satisfactory to Mortgagee,  in accordance with plans and specifications
satisfactory to Mortgagee and in compliance with all Legal Requirements,  and no
work shall  commence  until waivers of  mechanics'  liens have been filed by the
general  contractor  and all those  claiming by,  through,  or under the general
contractor;

              (f) Mortgagor shall have deposited with Mortgagee for disbursement
in connection with the restoration the greater of (i) the applicable  deductible
under the insurance  policies covering the loss; or (ii) the amount by which the
cost of restoration  is estimated by Mortgagee to exceed the insurance  proceeds
available for restoration;

              (g) The  insurance  proceeds are held by Mortgagee (or an escrowee
satisfactory  to Mortgagee) in trust,  to be disbursed  periodically as the work
progresses  in amounts  not  exceeding  90% of the value of labor and  materials
incorporated into the restoration. The remaining 10% will be released upon final
completion   of  the  work  in   accordance   with  the   aforesaid   plans  and
specifications,  and upon a receipt of a release  of liens from all  contractors
and subcontractors engaged in the restoration; and

              (h)  Mortgagor has paid as and when due all of  Mortgagee's  costs
and expenses  incurred in connection with the collection of insurance  proceeds,
approval of plans,  charges of Mortgagee's  inspection  representative  and such
reasonable  fee as may be charged by  Mortgagee to monitor the  restoration  and
disburse the insurance proceeds.

         5.2  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  attorney's  fees
incurred by Mortgagee in connection with the collection of such proceeds,  shall
be  paid  to  Mortgagee  and  applied,  at  Mortgagee's  election,   (i)  toward
restoration  of the Mortgaged  Property (in which case the terms and  conditions
applicable to restoration  in the case of casualty shall apply);  or (ii) to the
Obligations.  No  settlement  for damages  sustained  shall be made by Mortgagor
without Mortgagee's prior written approval.

              (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  anyone  other  than   Mortgagee  is  the  successful
purchaser at the  foreclosure  sale,  in addition to the net sale proceeds to be
received  by  Mortgagee  in  connection   with  the  sale,  any  deficiency  (as
hereinafter  defined) due to Mortgagee in connection with the foreclosure  sale,
with  legal  interest   thereon,   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 section,  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 Loan Documents,  and (B) the
aggregate  amount of all sums which  Mortgagee is entitled to collect  under the
Loan Documents.

              (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  will then be appointed 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 applied to the Obligations.

              (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.



                                   ARTICLE VI
                               DEFAULTS; REMEDIES

         6.1 Right to Make Advances.  If Mortgagor should fail to pay or perform
any of its Obligations with respect to the Mortgaged  Property as required under
Article  III and  Article  IV of this  Mortgage,  or  otherwise  fails to pay or
perform any of its other Obligations under this or any other Loan Document, then
Mortgagee,  at its election,  shall have the right,  but not the obligation,  to
made 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.  Such action shall be without prejudice
to any of Mortgagee's  rights or remedies  available  under this Mortgage or the
other Loan Documents or otherwise at law or in equity. All such sums, as well as
costs  and  expenses,  advanced  by  Mortgagee  shall  be due  immediately  from
Mortgagor to  Mortgagee,  shall become part of the  Obligations  secured by this
Mortgage and the other Loan Documents, and shall bear interest at the applicable
rate  provided in the Loan  Documents in effect  after  maturity or default (the
"Default Rate") until repayment in full to Mortgagee.

         6.2  Events  of  Default.  The  occurrence  of any  one or  more of the
following  events shall,  at the election of  Mortgagee,  constitute an Event of
Default under this Mortgage:

              (a) Any Event of Default under any other Loan Document;

              (b) Failure to pay any sum required to be paid under this Mortgage
as and when due;

              (c) Any breach of warranty  or other  violation  of any  provision
contained in Article II of this Mortgage;

              (d)   The   commencement   by   Mortgagor   of   any   bankruptcy,
reorganization, debt arrangement, or other case or proceeding under any state or
federal   bankruptcy  or  insolvency  law  or  any  dissolution  or  liquidation
proceeding;

              (e) Any bankruptcy,  reorganization,  debt  arrangement,  or other
case or proceeding  under any state or federal  bankruptcy or insolvency law, or
any dissolution or liquidation proceeding, involuntarily commenced against or in
respect of Mortgagor,  or an order for relief entered in such proceeding and not
dismissed  within the period of time, if any,  expressly  permitted by Mortgagee
under the Loan Documents; or

              (f)  Nonperformance   of,  or  noncompliance   with,  any  of  the
agreements,   covenants,  conditions,   warranties,   representations  or  other
provisions contained in this Mortgage (if and only to the extent not included in
any of the occurrences listed above),  which  nonperformance or noncompliance is
not cured and remedied within fifteen (15) days after notice thereof is given to
Mortgagor.

         6.3 Remedies;  Execution.  Upon the  occurrence of an Event of Default,
Mortgagee shall have the right to accelerate all Obligations (including interest
thereon at the Default Rate)  pursuant to the terms of the Loan Documents and to
enforce  its  rights  under  this  Mortgage  and the  other  Loan  Documents  by
exercising  such remedies as are available to Mortgagee  under  applicable  law,
either  by suit in  equity  or action  at law,  or both,  whether  for  specific
performance of any provision contained in this Mortgage or any of the other Loan
Documents or in aid of the exercise or any power granted in this Mortgage or the
other Loan Documents.

              (a)  Mortgagee  shall  have the right to obtain  judgment  for the
Obligations (including all amounts advanced or to be advanced by Mortgagee under
Section 6.1 above, all costs and expenses of collection and suit,  including any
bankruptcy  or  insolvency   proceeding  affecting  Mortgagor,   and  reasonable
attorneys' fees incurred in connection with any of the foregoing)  together with
interest on such  judgment at the Default Rate until payment in full is received
by Mortgagee and  Mortgagee  shall have the right to obtain  execution  upon the
Mortgaged Property on account of such judgment.

              (b)  Mortgagee  shall  have the  right to  institute  an action of
mortgage  foreclosure  against the Mortgaged  Property or take such other action
for realization on the security  intended to be provided under Article I of this
Mortgage as applicable law or the provisions of the Loan Documents may allow.

         6.4  Remedies;  Collection  of Income.  Mortgagee  may, with or without
entering into  possession of the Mortgaged  Property,  and with or without legal
action,  collect all income (which term shall also include amounts determined by
Mortgagee as fair rental value for use and occupation of the Mortgaged  Property
by any person, including Mortgagor) and, after deducting all costs of collection
and  administration  expense,  apply the net income to the Obligations or 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, or accumulation of necessary
reserves  for,  payment of all costs and  expenses  arising  from or incurred in
connection with (a) the preservation and protection of the validity and priority
of the  lien of  this  Mortgage;  (b) the  preservation  and  protection  of the
Mortgaged Property;  (c) compliance with Legal  Requirements;  or (d) fulfilling
any Obligations of Mortgagor under the Permitted Encumbrances,  the Leases, this
Mortgage or the Loan Documents.

         6.5 Remedies; Possession.  Mortgagee may, with or without legal action,
take  possession  and  control of the  Mortgaged  Property to the  exclusion  of
Mortgagor  and  all  others   excepting  only  those  claiming  under  Permitted
Encumbrances.  Mortgagee  shall have the  authority  while so in  possession  to
insure (at Mortgagor's expense) against all risks by reason of having taken such
possession and Mortgagor will transfer and deliver to the Mortgagee all policies
of  insurance  upon the  Mortgaged  Property  not  theretofore  transferred  and
delivered to Mortgagee. FOR THE PURPOSE OF OBTAINING POSSESSION OF THE MORTGAGED
PROPERTY  UPON  THE  OCCURRENCE  OF  ANY  EVENT  OF  DEFAULT,  MORTGAGOR  HEREBY
AUTHORIZES  AND  EMPOWERS  ANY  ATTORNEY  OF ANY COURT OF RECORD IN THE STATE IN
WHICH THE  MORTGAGED  PROPERTY IS LOCATED OR ELSEWHERE AS ATTORNEY FOR MORTGAGOR
AND ALL PERSONS  CLAIMING UNDER OR THROUGH  MORTGAGOR,  TO SIGN AN AGREEMENT FOR
ENTERING IN ANY COMPETENT  COURT AN AMICABLE  ACTION IN EJECTMENT FOR POSSESSION
OF THE  MORTGAGED  PROPERTY  AND TO  APPEAR  FOR AND  CONFESS  JUDGMENT  AGAINST
MORTGAGOR,  AND ALL  PERSONS  CLAIMING  UNDER OR THROUGH  MORTGAGOR  IN FAVOR OF
MORTGAGEE  FOR  RECOVERY BY  MORTGAGEE  OF  POSSESSION  THEREOF,  FOR WHICH THIS
MORTGAGE, OR A COPY THEREOF VERIFIED BY AFFIDAVIT,  SHALL BE SUFFICIENT WARRANT;
AND THEREUPON A WRIT OF POSSESSION MAY  IMMEDIATELY  ISSUE FOR POSSESSION OF THE
MORTGAGED PROPERTY,  WITHOUT ANY PRIOR WRIT OR PROCEEDING WHATSOEVER AND WITHOUT
ANY STAY OF EXECUTION. IF FOR ANY REASON AFTER SUCH ACTION HAS BEEN COMMENCED IT
SHALL BE DISCONTINUED,  OR POSSESSION OF THE MORTGAGED  PROPERTY SHALL REMAIN IN
OR BE RESTORED TO MORTGAGOR, MORTGAGEE SHALL HAVE THE RIGHT FOR THE SAME DEFAULT
OR ANY SUBSEQUENT DEFAULT TO BRING ONE OR MORE FURTHER AMICABLE ACTIONS AS ABOVE
PROVIDED TO RECOVER POSSESSION OF THE MORTGAGED PROPERTY. MORTGAGEE MAY BRING AN
AMICABLE  ACTION IN EJECTMENT  BEFORE OR AFTER THE INSTITUTION OF PROCEEDINGS TO
FORECLOSE  THIS  MORTGAGE  OR TO ENFORCE  ANY LOAN  DOCUMENT,  OR AFTER ENTRY OF
JUDGMENT  THEREON  OR ON ANY LOAN  DOCUMENT,  OR AFTER A  SHERIFF'S  SALE OF THE
MORTGAGED  PROPERTY IN WHICH  MORTGAGEE IS THE SUCCESSFUL  BIDDER,  IT BEING THE
UNDERSTANDING  OF THE PARTIES THAT THE  AUTHORIZATION TO PURSUE SUCH PROCEEDINGS
FOR OBTAINING POSSESSION IS AN ESSENTIAL PART OF THE REMEDIES FOR ENFORCEMENT OF
THIS MORTGAGE AND THE OTHER LOAN DOCUMENTS, AND SHALL SURVIVE ANY EXECUTION SALE
TO MORTGAGEE.

         BY AGREEING THAT MORTGAGEE MAY CONFESS  JUDGMENT  HEREUNDER  MORTGAGOR,
FOR ITSELF AND ANY OTHER  PERSONS OR ENTITIES NOW OR HEREAFTER IN  POSSESSION OF
ALL OR ANY PART OF THE MORTGAGED PROPERTY, WAIVES THE RIGHT TO NOTICE IN A PRIOR
JUDICIAL   PROCEEDING  TO  DETERMINE   THEIR  RIGHTS  AND  LIABILITIES  AND  THE
OPPORTUNITY TO RAISE ANY DEFENSE,  SET OFF,  COUNTERCLAIM OR OTHER CLAIM AGAINST
SUCH ACTION BY MORTGAGEE.

         6.6  Remedies;  Repossession.  Mortgagee  shall  have the right to take
possession of any portion of the  Mortgaged  Property  constituting  fixtures or
personal  property subject to the Uniform  Commercial Code of the state in which
the Mortgaged Property is located, and any records pertaining thereto. Mortgagee
shall have the right to use,  operate,  manage,  lease or otherwise  control the
Mortgaged  Property in any lawful manner and, in its sole discretion but without
any obligation to do so, insure,  maintain,  repair,  renovate,  alter or remove
such  Mortgaged  Property;   use,  in  connection  with  any  assembly,  use  or
disposition of such Mortgaged  Property any trade mark, trade name, trade style,
copyright,  brand,  patent  right  or  technical  process  used or  utilized  by
Mortgagor; sell or otherwise dispose of all or any of such Mortgaged Property at
any public or private sale at any time or times without  advertisement or demand
upon or notice to  Mortgagor,  all of which are  expressly  waived to the extent
permitted by law, with the right of Mortgagee or its nominee to become purchaser
at any sale (unless  prohibited  by statute)  free from any equity of redemption
and from all other claims,  and after deducting all legal and other expenses for
maintaining or selling such Mortgaged  Property,  and all attorneys' fees, legal
or other  expenses  for  collection,  sale and  delivery,  apply  the  remaining
proceeds of any sale to pay (or hold as a reserve  against) the  Obligations and
exercise all rights and remedies of a secured party under the Uniform Commercial
Code of the  state in which  the  Mortgaged  Property  is  located  or any other
applicable law.

         6.7 Remedies;  Actions Prior to Acceleration.  Mortgagee shall have the
right,  from time to time, to bring an appropriate  action or actions to recover
any sums required to be paid by Mortgagor  under the terms of this Mortgage,  as
they become due,  without regard to whether or not the Obligations  shall be due
and payable in full, and without prejudice to the right of Mortgagee  thereafter
to bring an action of mortgage foreclosure, or any other action, for any default
by Mortgagor existing at the time the earlier action was commenced.

         6.8 No Marshalling.  Any of the Mortgaged Property sold pursuant to any
writ of execution  issued on a judgment  obtained on the Obligations or pursuant
to any  other  judicial  proceeding  relating  to the  Loan  Documents  or  this
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.

         6.9  Rights and Remedies Cumulative.

              (a) All rights and  remedies  of  Mortgagee  as  provided  in this
Mortgage and the other Loan Documents shall be cumulative and concurrent, may be
pursued separately,  successively or together against Mortgagor or the Mortgaged
Property,  or both, at the sole  discretion of Mortgagee and may be exercised as
often as occasion  therefor 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 terms and  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 this 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.


                                   ARTICLE VII
                                  MISCELLANEOUS

         7.1 Costs,  Fees and Expenses.  If the Mortgagee becomes a party to any
suit or proceeding  affecting the Mortgaged  Property,  title thereto,  the lien
created by this Mortgage or Mortgagee's interest therein, or in the event of the
commencement of any bankruptcy or insolvency proceedings involving Mortgagor, or
if  Mortgagee  engages  counsel  to collect  or to  enforce  performance  of the
Obligations,  Mortgagee's  reasonable  counsel  fees,  and all  other  costs and
expenses paid or incurred by Mortgagee, including reasonable fees of appraisers,
accountants,  consultants,  and  other  professionals,  costs of title  and lien
searches, and environmental assessments, investigations, and other environmental
costs  and  expenses,  whether  or not  suit  is  instituted,  shall  be paid to
Mortgagee,  on demand,  with  interest at the  Default  Rate and until paid they
shall be deemed to be part of the Obligations secured by this Mortgage.

         7.2 Indemnity.  Mortgagor  shall  indemnify,  defend and hold Mortgagee
harmless from and against any claims, expenses, demands, losses, costs, fines or
liabilities of any kind  (including  those involving  death,  personal injury or
property damage and including reasonable attorneys' fees and costs) arising from
or in any way related to the failure of Mortgagor to comply with, or the failure
of the Mortgaged Property to be kept in compliance with, the Legal Requirements,
Applicable  Environmental laws, the Leases and the Permitted  Encumbrances.  The
Indemnification  of Mortgagor  under this section  shall  survive the release or
termination  of this  Mortgage and shall remain  effective  notwithstanding  any
foreclosure of this Mortgage or other execution  against the Mortgaged  Property
or acceptance of a deed in lieu of foreclosure. The indemnification agreement of
Mortgagor  under this section is  specifically  excepted from any  limitation of
liability provision contained in this or any other Loan Document.

         7.3 Declaration of No Set-Off.  Within ten (10) days after requested to
do so by  Mortgagee,  Mortgagor  shall  certify to  Mortgagee or to any proposed
assignee of this Mortgage or  participant  in the  Obligations in a writing duly
acknowledged,  the amount of principal, interest and other charges then owing on
the  Obligations  secured by this  Mortgage  and whether  there are  set-offs or
defenses against them.

         7.4  Communications.  All notices required under this Mortgage shall be
in writing and shall be delivered in accordance  with the applicable  provisions
contained in the Obligations  Secured. If the Obligations Secured do not contain
any  applicable  provisions  for the giving of notices,  then notices under this
Mortgage shall be in writing and shall be given by either (a) hand-delivery; (b)
first class mail (postage prepaid);  (c) reliable  overnight  commercial courier
(charges prepaid); or (d) telecopy or other means of electronic transmission, if
confirmed  promptly by any of the methods  specified in clauses (a), (b) and (c)
of this sentence to the parties at their  respective  addresses set forth at the
beginning  of this  Mortgage.  A party may change its address by giving  written
notice to the other party as specified herein.

         7.5  Covenant  Running with the Land.  Any act or  agreement  specified
herein to be done or  performed  by  Mortgagor  shall be construed as a covenant
running with the land and shall be binding upon Mortgagor and its successors and
assigns as if each had personally made such agreement.

         7.6 Amendment. Any amendment, modification, consent or waiver which may
be hereafter requested by Mortgagor or otherwise required must be in writing and
signed by both  Mortgagor  and  Mortgagee.  Mortgagor  shall  promptly  pay ( or
reimburse,  as Mortgagee may elect) all costs and expenses  which  Mortgagee may
incur in  connection  with  any  amendment,  modification,  consent  or  waiver,
including the fees and  reimbursements of professional  advisors and consultants
to  Mortgagee  (including  legal  counsel),   title  information  and  premiums,
recording costs and appraisal fees (including any reappraisal  deemed  necessary
by Mortgagee).

         7.7 Applicable Law. This Mortgage shall be governed by and construed in
accordance  with the law of the state chosen by the parties under the applicable
provision contained in the Obligations Secured except to the extent that rights,
remedies  and warrants of attorney  which relate to realizing  upon the security
covered  by this  Mortgage  are  governed  by the laws of the state in which the
Mortgaged  Property  is  located.  Whenever  possible,  each  provision  of this
Mortgage  shall be interpreted in such manner as to be effective and valid under
applicable law, but if any provision of this Mortgage shall be prohibited by, or
invalid under, applicable law, such provision shall be ineffective to the extent
of such prohibition and invalidity without invalidating the remaining provisions
of this  Mortgage.  Nothing  contained  in this  Mortgage  or in any other  Loan
Document shall require Mortgagor to pay, or Mortgagee to accept,  interest in an
amount which would subject Mortgagee to penalty under applicable law.

         7.8  Construction.  Whenever used in this Mortgage,  unless the context
clearly indicates a contrary intent:

              (a) The word  "Mortgagor"  shall mean the persons who execute this
Mortgage  and any  subsequent  fee  owner of the  Mortgaged  Property  and their
respective   heirs,   executors,   administrators,   personal   representatives,
successors, and assigns;

              (b) The word  "Mortgagee"  shall  mean,  collectively,  all of the
entities  listed  as  Mortgagee  hereinabove  or any  subsequent  holder of this
Mortgage or participant in the Loan;

              (c)  The  word  "person"  shall  mean   individual,   corporation,
partnership or unincorporated association;

              (d) The use of any gender shall include all genders;

              (e) The singular  number  shall  include the plural and the plural
the singular as the context may require;

              (f) The word "including" shall mean "including but not limited to"
or "including without limitation" as the context may require.

         7.9 Liability.  If Mortgagor, or any successor or grantee of Mortgagor,
shall be more than one person,  all Obligations of Mortgagor under this Mortgage
shall be joint and several and shall bind and affect all persons who are defined
as  "Mortgagor"  as fully as though all of them were  specifically  named herein
wherever the word "Mortgagor" is used. Any Mortgagor who signs this Mortgage but
does not sign the Obligations Secured: (a) is signing this Mortgage to mortgage,
grant  and  convey  that  Mortgagor's  interest  in the  Mortgaged  Property  to
Mortgagee under the terms of this Mortgage,  (b) is not personally  obligated to
pay the principal sum evidenced by the Obligations  Secured (but is obligated to
reimburse  Mortgagee  with interest at the Default Rate for advances made by the
Mortgagee  to protect the security of this  Mortgage  arising from or related to
the failure of Mortgagor to pay or perform its  obligations  with respect to the
Mortgaged  Property under this Mortgage),  and (c) agrees that Mortgagee and any
obligor may agree to extend,  modify,  forbear or make any other  accommodations
with regard to the terms of this  Mortgage or the  Obligations  Secured  without
Mortgagor's consent.

         7.10  Headings.  The  headings of sections  have been  included in this
Mortgage  for  convenience  of  reference  only and shall not be  considered  in
interpreting this Mortgage.

         7.11 Severability.  If any provision of this Mortgage shall be held for
any reason to be invalid,  illegal or  unenforceable,  such impairment shall not
affect any other provision of this Mortgage.

         7.12  Incorporation  by  References.   The  legal  description  of  the
Mortgaged  Property attached as Exhibit "A", the list of Permitted  Encumbrances
(if any)  attached as Exhibit "B", and any  Rider(s)  executed by Mortgagor  and
attached to this Mortgage are incorporated into this Mortgage by this reference.

         7.13  Receipt of Copy.  Mortgagor  acknowledges  receipt  of  conformed
copies of the Obligations Secured and this Mortgage.






 IN WITNESS WHEREOF,  Mortgagor,  intending to be legally bound hereby, has duly
