                  advances  together with any interest  thereon or other charges
                  as provided in the Security  Documents,  and the  balance,  if

                  Leases of even date  herewith (the  "Mortgage")  from Maker to
                                                       --------
                  Payee and by an  Assignment  of Rents and  Leases of even date
                  herewith (the "Assignment") from Maker to Payee. The Mortgage,
                                 ----------
                  the Assignment and any other  instrument  given at any time to
                  secure  this  Note are  hereinafter  collectively  called  the
                  "Security Documents."
                   -------- ---------

                           (d) This Note may not be prepaid  prior to the end of
                  the Lockout Period, except as set forth herein. Any prepayment
                  of this  Note,  in whole  or in part,  prior to the end of the
                  Lockout Period,  except as permitted herein,  shall constitute
                  an "Event of Default" under the Mortgage.  Maker has the right
                  to prepay the principal of this Note in full or in part on any
                  Payment Date after the end of the Lockout  Period,  upon sixty
                  days' prior  written  notice and  payment,  together  with the
                  portion  of  the  principal  to be  prepaid,  of a  prepayment
                  premium in an amount  calculated  as  specified in Appendix 1.
                  The  calculation  of the  prepayment  premium shall be made by
                  Payee and shall, absent manifest error, be conclusive.  In the
                  event this Note is prepaid  from the  proceeds of insurance or
                  condemnation  awards in accordance with Sections 10, 11 and 12
                  of the  Mortgage  either  prior  to or  after  the  end of the
                  Lockout  Period,   a  prepayment   premium  shall  be  payable
                  calculated  as  specified in Appendix 1.  Notwithstanding  the
                  foregoing,  this  Note may be  prepaid  without  a  prepayment
                  premium  during the one hundred  eighty (180) day period prior

                                                             Loan No. 55-9506016


                  to the  Maturity  Date.  Upon  acceleration  of  this  Note in
                  accordance  with  its  terms  and the  terms  of the  Security
                  Documents,   Maker  agrees  to  pay  the  prepayment   premium
                  described above in the amount that would be due if a voluntary
                  payment were made on the date of such  acceleration.  A tender
                  of payment  of the amount  necessary  to pay and  satisfy  the
                  entire  unpaid  principal  balance of this Note or any portion
                  thereof  at any  time  after an Event  of  Default  under  the
                  Mortgage  or an  acceleration  by  Payee  of the  indebtedness
                  evidenced   hereby,   whether   such   payment   is   tendered
                  voluntarily,  during or after foreclosure of the Mortgage,  or
                  pursuant to realization upon other security,  shall constitute
                  a  purposeful  evasion of the  prepayment  terms of this Note,
                  shall be deemed to be a voluntary prepayment hereof, and Maker
                  shall be required to pay the  prepayment  premium as described
                  above.  Partial  prepayments of principal shall not change the
                  Payment Dates or amounts of subsequent  monthly  installments,
                  unless Payee shall otherwise agree in writing. Notwithstanding
                  the  foregoing,  nothing in this  paragraph  (d) shall vary or
                  negate the provisions of Section 18(c) of the Mortgage.

                           (e)  If  Maker   defaults   in  the  payment  of  any
                  installment  of principal and interest on the date on which it
                  shall fall due or in the performance of any of the agreements,
                  conditions, covenants, provisions or stipulations contained in
                  this Note or in the  Security  Documents,  and if such default
                  shall  continue  beyond any grace  period  provided for in the
                  Mortgage so as to constitute  an Event of Default  thereunder,
                  then Payee, at its option and without further notice to Maker,
                  may declare  immediately  due and  payable  the entire  unpaid
                  principal balance of this Note, together with interest thereon
                  at an annual rate after the date of such default  equal to the
                  Default  Rate,  together  with all sums due by Maker under the
                  Security  Documents,   anything  herein  or  in  the  Security
                  Documents  to  the  contrary  notwithstanding.  The  foregoing
                  provision  shall not be  construed as a waiver by Payee of its
                  right to pursue any other  remedies  available to it under the
                  Mortgage,  this Note or any other Security Document, nor shall
                  it be  construed  to limit in any way the  application  of the
                  Default  Rate.  Any  payment  hereunder  may be  enforced  and
                  recovered  in whole or in part at such  time by one or more of
                  the remedies provided to Payee in this Note or in the Security
                  Documents.  In the event that:  (i) this Note or any  Security
                  Document is placed in the hands of an attorney for  collection
                  or enforcement  or is collected or enforced  through any legal
                  proceeding; (ii) an attorney is retained to represent Payee in
                  any  bankruptcy,   reorganization,   receivership,   or  other
                  proceedings  affecting creditors' rights and involving a claim
                  under this Note or any Security Document; (iii) an attorney is
                  retained to protect or enforce the lien of the Mortgage or any
                  Security  Document;   or  (iv)  an  attorney  is  retained  to
                  represent  Payee  in  any  other  proceedings   whatsoever  in
                  connection  with this Note, the Mortgage,  any of the Security
                  Documents or any portion of the Mortgaged Property (as defined
                  in the Mortgage), then Maker shall pay to Payee all reasonable
                  attorney's  fees,  costs and expenses  incurred in  connection

                                                             Loan No. 55-9506016


                  therewith,  including costs of appeal,  together with interest
                  on any judgment obtained by Payee at the Default Rate.

                           (f) If Maker  defaults  in the payment of any monthly
                  installment on the Payment Date, and such default is not cured
                  within five days  thereafter,  then Maker shall pay to Payee a
                  late payment  charge in an amount equal to six percent (6%) of
                  the  amount  of the  installment  not  paid as  aforesaid.  An
                  additional  late  charge  equal  to six  percent  (6%)  of the
                  monthly payment due will be charged for each successive  month
                  the payment remains outstanding. Said late charge payments, if
                  payable,  shall  be  secured  by the  Mortgage  and the  other
                  Security Documents,  shall be payable without notice or demand
                  by Payee,  and are  independent of and have no effect upon the
                  rights of Payee under paragraph (e) above.

                           (g) Maker and all endorsers,  sureties and guarantors
                  hereby jointly and severally  waive all  applicable  exemption
                  rights,  valuation and appraisement,  presentment for payment,
                  demand,  notice of demand,  notice of  nonpayment or dishonor,
                  protest  and notice of  protest  of this  Note,  and all other
                  notices  in   connection   with  the   delivery,   acceptance,
                  performance,  default or  enforcement  of the  payment of this
                  Note. Maker and all endorsers, sureties and guarantors consent
                  to any  and all  extensions  of  time,  renewals,  waivers  or
                  modifications that may be granted by Payee with respect to the
                  payment or other provisions of this Note and to the release of
                  the   collateral  or  any  part   thereof,   with  or  without
                  substitution,  and agree that  additional  makers,  endorsers,
                  guarantors  or  sureties  may become  parties  hereto  without
                  notice to them or affecting their liability hereunder.

                           (h) Payee shall not be deemed, by any act of omission
                  or  commission,  to have  waived any of its rights or remedies
                  hereunder  unless  such  waiver is in  writing  and  signed by
                  Payee,  and then only to the extent  specifically set forth in
                  writing.  A waiver of one  event  shall  not be  construed  as
                  continuing  or as a bar to or waiver of any right or remedy to
                  a subsequent event.

                           (i) This Note shall be governed by and  construed  in
                  accordance  with the laws of the State in which the  Mortgaged
                  Property is located (the "State").
                                            -----

                           (j) The parties  hereto  intend and believe that each
                  provision  in this  Note  comports  with all  applicable  law.
                  However,  if any provision in this Note is found by a court of
                  law to be in  violation  of any  applicable  law,  and if such
                  court  should  declare  such  provision  of  this  Note  to be
                  unlawful,  void or  unenforceable  as written,  then it is the
                  intent of all  parties  hereto  that such  provision  shall be
                  given  full force and effect to the  fullest  possible  extent
                  that is legal,  valid and  enforceable,  that the remainder of
                  this Note  shall be  construed  as if such  unlawful,  void or
                  unenforceable  provision were not contained therein,  and that
                  the rights,  obligations  and interest of Maker and the holder

                                                             Loan No. 55-9506016


                  hereof under the remainder of this Note shall continue in full
                  force and effect; provided,  however, that if any provision of
                                    --------   -------
                  this Note which is found to be in violation of any  applicable
                  law concerns the imposition of interest hereunder, the rights,
                  obligations  and  interests of Maker and Payee with respect to
                  the  imposition  of interest  hereunder  shall be governed and
                  controlled by the provisions of the following paragraph.

                           (k) It being  the  intention  of Payee  and  Maker to
                  comply  with the laws of the State with  regard to the rate of
                  interest charged hereunder, it is agreed that, notwithstanding
                  any provision to the contrary in this Note,  the Mortgage,  or
                  any  of the  other  Security  Documents,  no  such  provision,
                  including  without  limitation  any  provision  of  this  Note
                  providing for the payment of interest or other charges,  shall
                  require  the  payment or permit the  collection  of any amount
                  ("Excess  Interest")  in  excess  of  the  maximum  amount  of

                  interest  permitted  by  law  to be  charged  for  the  use or
                  detention, or the forbearance in the collection, of all or any
                  portion of the  indebtedness  evidenced  by this Note.  If any
                  Excess  Interest is  provided  for,  or is  adjudicated  to be
                  provided for, in this Note, the Mortgage,  or any of the other
                  Security Documents, then in such event:

                                    (i)  the provisions of this paragraph shall
                                         govern;

                                    (ii) Maker  shall not  be  obligated to pay

                                    (iii) any  Excess  Interest  that  Payee may
                           have  received  hereunder  shall,  at the  option  of
                           Payee,  be (x) applied as a credit against the unpaid
                           principal  balance then due under this Note,  accrued
                           and unpaid interest thereon not to exceed the maximum
                           amount permitted by law, or both, (y) refunded to the
                           payor   thereof  or  (z)  any   combination   of  the
                           foregoing;

                                    (iv) the  applicable  interest rate or rates
                           provided for herein shall be automatically subject to
                           reduction  to the maximum  lawful rate  allowed to be
                           contracted for in writing under the applicable  usury
                           laws of the  aforesaid  State,  and  this  Note,  the

                           deemed  to have  been,  and shall  be,  reformed  and
                           modified to reflect such  reduction in such  interest
                           rate or rates; and

                                    (v)  Maker  shall  not  have any  action  or
                           remedy  against  Payee for any damages  whatsoever or

                           (l)  Upon  any  endorsement,   assignment,  or  other

                  term  "Payee,"  as used  herein,  shall  mean  such  endorsee,
                  assignee,  or other  transferee  or  successor  to Payee  then
                  becoming the holder of this Note. This Note shall inure to the

                                                             Loan No. 55-9506016


                  benefit of Payee and its  successors  and assigns and shall be
                  binding upon the  undersigned  and its successors and assigns.
                  The term "Maker" as used herein shall  include the  respective
                  successors  and assigns,  legal and personal  representatives,
                  executors,  administrators,  devisees,  legatees  and heirs of
                  Maker.

                           (m) Any notice,  demand or other  communication which
                  any party may desire or may be  required  to give to any other
                  party  shall be in writing  and shall be given as  provided in
                  the Mortgage.

                           (n) To the extent that Maker makes a payment or Payee
                  receives  any payment or proceeds for Maker's  benefit,  which
                  are  subsequently  invalidated,  declared to be  fraudulent or
                  preferential, set aside or required to be repaid to a trustee,
                  debtor in possession,  receiver,  custodian or any other party
                  under any bankruptcy law, common law or equitable cause, then,
                  to such extent, the obligations of Maker hereunder intended to
                  be satisfied  shall be revived and continue as if such payment
                  or proceeds had not been received by Payee.

                           (o) Maker shall execute and  acknowledge (or cause to
                  be  executed  and  acknowledged)  and  deliver  to  Payee  all
                  documents, and take all actions,  reasonably required by Payee
                  from time to time to  confirm  the  rights  created  or now or
                  hereafter  intended  to be  created  under  this  Note and the
                  Security  Documents,  to protect  and  further  the  validity,
                  priority  and  enforceability  of this  Note and the  Security
                  Documents,  to subject to the Security  Documents any property
                  of  Maker  intended  by the  terms  of any  one or more of the
                  Security Documents to be encumbered by the Security Documents,
                  or otherwise carry out the purposes of the Security  Documents
                  and  the  transactions   contemplated  thereunder;   provided,
                  however,   that  no  such  further  actions,   assurances  and
                  confirmations  shall increase Maker's  obligations  under this
                  Note.

                           (p) No modification, amendment, extension, discharge,
                  termination or waiver (a  "Modification")  of any provision of
                                             ------------
                  this Note, or any one or more of the other Security Documents,
                  nor consent to any departure by Maker therefrom,  shall in any
                  event  be  effective  unless  the same  shall be in a  writing
                  signed by the party against whom  enforcement  is sought,  and
                  then such  waiver or consent  shall be  effective  only in the
                  specific  instance,  and for the  purpose,  for  which  given.
                  Except as otherwise  expressly  provided herein, no notice to,
                  or demand on, Maker shall entitle Maker to any other or future
                  notice or demand in the same, similar or other  circumstances.
                  Payee does not hereby agree to, nor does Payee  hereby  commit
                  itself to, enter into any Modification.

                           (q)  Maker  hereby   expressly  and   unconditionally
                  waives,  in  connection  with any suit,  action or  proceeding
                  brought by Payee on this Note, any and every right it may have
                  to (a) a trial by jury, (b) interpose any counterclaim therein
                  (other than a  counterclaim  which can only be asserted in the
                  suit,  action or proceeding  brought by Payee on this Note and

                                                             Loan No. 55-9506016


                  cannot be  maintained  in a separate  action) and (c) have the
                  same  consolidated  with any other or separate suit, action or
                  proceeding.

                           (r)  Notwithstanding any provision to the contrary in
                  the  Mortgage or this Note,  Payee shall not have any recourse
                  to any asset of Maker or its partners other than the Mortgaged
                  Property in order to satisfy the  indebtedness  for payment of
                  the principal and interest evidenced by this Note, and Payee's
                  sole recourse for satisfaction of the payment of principal and
                  interest  evidenced  by this  Note  shall be to  exercise  its
                  rights  against  the  Mortgaged  Property  encumbered  by  the
                  Mortgage  and the other  collateral  securing  this Note.  The
                  foregoing  sentence  shall not be deemed or  construed to be a
                  release of the  indebtedness  evidenced by this Note or in any
                  way impair, limit or otherwise affect the lien of the Mortgage
                  or any such other instrument  securing  repayment of this Note
                  or prevent  Payee from naming Maker,  its  partners,  or their
                  successors  or assigns as a defendant to any action to enforce
                  any remedy for default or prevent  Payee from  exercising  any
                  assignments  of rents and leases or obtaining the  appointment
                  of a receiver so long as there is no  personal  or  deficiency
                  money judgment sought or entered against Maker,  its partners,
                  or their  successors  or assigns for payment of principal  and
                  interest evidenced by this Note. Notwithstanding the foregoing
                  provisions of this paragraph,  it is expressly  understood and
                  agreed that the aforesaid limitation of liability shall no way
                  affect or apply to Maker's or its partners' continued personal
                  liability for the payment to Payee of:

                           (i) any loss or damage  occurring by reason of all or
                           any part of the Mortgaged  Property being  encumbered
                           by a voluntary lien (other than the Mortgage) granted
                           by Maker;

                           (ii) any Rents (as defined in the Mortgage),  issues,
                           profits and/or income collected by Maker in excess of
                           normal and  verifiable  operating  expenses  from the
                           Mortgaged  Property after default by Maker hereunder,
                           under the  Mortgage  or under  any  other  instrument
                           securing or referring to this Note;

                           (iii) unrefunded  security deposits  made by tenants 
                           of the Mortgaged Property;

                           (iv) payment of Taxes, as defined in Section 5 of the
                           Mortgage, and insurance premiums, payment of which is
                           required to be made by Maker under the Mortgage;

                           (v) Rents,  security  deposits with respect to leases
                           of  the  Mortgaged   Property,   insurance  proceeds,
                           condemnation   awards  and  any  other   payments  or

                           committed or permitted by Maker;

                           (vii) loss  or  damage   occurring  by reason of the
                           failure  of Maker to comply  with any
                           of the provisions of Section 35 of the Mortgage;

                           (viii)  any loss or  claim  incurred  by or  asserted
                           against    Payee   as   a   result    of   fraud   or
                           misrepresentation  by  Maker  or any of the  partners
                           thereof   with   respect   to   any    certification,
                           representation  or  warranty  made by  Maker  or such
                           other  persons  to  Payee  herein  or in  any  of the
                           Security Documents;

                                   ----------

                       Calculation of Prepayment Premium
                       ---------------------------------


                  The  prepayment  premium  shall be equal to the greater of (A)
one  percent  (1%) of the  portion  of the  principal  amount of this Note being
repaid or (B) the product of (i) a fraction  whose  numerator is an amount equal
to the  portion of the  principal  balance of this Note being  prepaid and whose
denominator is the entire outstanding principal balance of this Note on the date
of such  prepayment  (after  subtracting  the amount of any scheduled  principal
payment due on such  Payment  Date),  multiplied  by (ii) an amount equal to the
remainder  obtained by subtracting (x) an amount equal to the entire outstanding
principal  balance  of this  Note  as of the  date  of  such  prepayment  (after
subtracting  the amount of any scheduled  principal  payment due on such Payment
Date)  from  (y) the  present  value as of the  date of such  prepayment  of the
remaining  scheduled  payments of principal and interest on this Note (including
any final  installment of principal  payable on the Maturity Date) determined by
discounting such payments at the Discount Rate (as hereinafter defined).

For purposes of this Note:

         (x)      "Discount  Rate" shall mean the rate which,  when compounded 
                   --------------
                  monthly,  is equivalent to the Treasury Rate (defined below);
                  and

         (y)      "Treasury Rate" shall mean the yield  calculated by the linear
                   -------------
                  interpolation  of the yield,  as reported  in Federal  Reserve
                  Statistical  Release  H.15-Selected  Interest  Rates under the
                  heading   "U.S.   government    securities/Treasury   constant
                  maturities"  for the  week  ending  prior  to the  date of the
                  relevant  prepayment of this Note, of U.S.  Treasury  constant
                  maturities  with a maturity  date (one longer and one shorter)
                  most nearly  approximating  the Maturity Date of this Note. In
                  the event Release H.15 is no longer published, the Payee shall
                  select a  comparable  publication  to  determine  the Treasury
                  Rate.
