     FOR VALUE RECEIVED,  WOODCREEK FUND XXI, L.P., a Texas limited  partnership

                   percent (8.48%) per annum.

                   through August 1, 1999.

                  "Monthly  Amount" shall  be  the  sum of  Twenty-One  Thousand
                   Five Hundred  Eighty-Five  and 84/100 Dollars ($21,585.84).

                  "Payment  Date" shall be the first  business day of each month

                   commencing on the first business day of the second full month
                   after  the  closing date and continuing to and including the
                   Maturity Date.

                  "Principal  Amount" shall be Two Million Eight Hundred  Twelve
                   Thousand Five Hundred and No/100 United States Dollars.

                                                             Loan No. 55-9506015

     (a) On the date  hereof,  all  accrued  and unpaid  interest  on the unpaid
balance  through the end of the month in which the Closing  Date occurs shall be
due and payable.  Thereafter,  commencing on the Commencement Date, eighty-three
(83) equal monthly  installments of principal and interest at the Monthly Amount
each shall be due and payable.  Each installment of principal and interest shall
be  applied  first  to  interest  and the  remainder  thereof  to  reduction  of
principal.  Each  monthly  installment  shall be due on each  Payment  Date.  In
addition, all amounts advanced by Payee pursuant to applicable provisions of the
Security Documents (as hereinafter  defined),  together with any interest at the
Default Rate or other charges as therein provided,  shall be immediately due and
payable  hereunder.  In the  event any such  advance  is not so repaid by Maker,
Payee may, at its option,  first apply any payments received  hereunder to repay
said advances together with any interest thereon or other charges as provided in
the Security Documents,  and the balance, if any, shall be applied in payment of
any installment  then due. The entire  remaining  unpaid balance of principal of
this Note, all interest accrued thereon and all other sums payable  hereunder or
under the  Security  Documents  shall be due and payable in full on the Maturity
Date.

     (b) Amounts due on this Note shall be  payable,  without any  counterclaim,
setoff or deduction whatsoever,  at the office of Payee or its agent or designee
at the  address  set forth in Exhibit 1 or at such  other  place as Payee or its
agent or designee may from time to time designate in writing.

     (c) This Note is secured by a Deed of Trust,  Mortgage,  Security Agreement
and Assignment of Rents and 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



                                                             Loan No. 55-9506015

premium  during the one hundred  eighty  (180) day period  prior 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


                                                             Loan No. 55-9506015
Payee all reasonable  attorney's fees, costs and expenses incurred in connection
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


                                                             Loan No. 55-9506015

the holder 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 any Excess Interest;

          (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 Mortgage and the other Security  Documents  shall be
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 any defense to enforcement of this Note,  Mortgage  or any
other  Security  Document  arising  out  of the  payment  or  collection  of any
Excess Interest.

          (l)Upon any endorsement, assignment, or other transfer of this Note by
Payee or by operation of law, the 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  benefit  of Payee and its


                                                             Loan No. 55-9506015

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


                                                             Loan No. 55-9506015

          (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  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 consideration  which  Maker  receives and to which Payee is entitled
pursuant to the terms of the Mortgage or of any other Security Document;


                                                             Loan No. 55-9506015

               (vi) damage  to  the  Mortgaged  Property from waste 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;

               (ix) all indebtedness and  obligations  arising under or pursuant
to that certain Environmental  Indemnity dated of even date herewith executed by
Maker, the general partner of Maker and McNeil Real Estate  Fund XXI,  L.P.  for
the benefit of Payee; and

               (x) reasonable  attorney's  fees  incurred by Payee in connection
with suit filed on account of any of the foregoing clauses (i) through (ix).

     IN WITNESS WHEREOF, Maker has caused this Note to be executed and delivered
as of the day and year first above written.

                                   APPENDIX 1

                       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.
