WHEREAS,  The  parties  hereto wish to provide  for  the  orderly
operation  and  management of the Premises  and  ▇.  ▇▇▇▇▇▇▇▇▇▇`s
interest  by Fund XX; the continued leasing of space  within  the
Premises;  for the distribution of income from and  the  pro-rata
sharing in expenses of the Premises.
NOW  THEREFORE, in consideration of the purchase by ▇. ▇▇▇▇▇▇▇▇▇▇
of an undivided interest in and to the Premises, for at least One
Dollar  ($1.00) and other good and valuable consideration by  the
parties  hereto  to  one another in hand paid,  the  receipt  and
sufficiency of which are hereby acknowledged, and of  the  mutual
covenants and agreements herein contained, it is hereby agreed by
and between the parties hereto, as follows:
1.    The  operation  and  management of the  Premises  shall  be
delegated  to  Fund  XX, or its designated agent,  successors  or
assigns.  Provided, however, if Fund XX shall  sell  all  of  its
interest in the Premises, the duties and obligations of  Fund  XX
respecting  management  of  the Premises  as  set  forth  herein,
including but not limited to paragraphs 2, 3, and 4 hereof, shall
be exercised by the holder or holders of a majority undivided co-
tenancy interest in the Premises. Except as hereinafter expressly
provided to the contrary, each of the parties hereto agrees to be
bound   by  the  decisions  of  Fund  XX  with  respect  to   all
administrative,  operational  and  management  matters   of   the
property  comprising the Premises, including but not  limited  to
the  management of the net lease agreement for the  Premises.  ▇.
▇▇▇▇▇▇▇▇▇▇  hereto  hereby designates Fund XX  as  its  sole  and
exclusive agent to deal with, and Fund XX retains the sole  right
to  deal  with any property agent or tenant and to negotiate  and
enter into, on terms and provisions satisfactory to Fund XX,  and
to  monitor,  execute and enforce the terms of  leases  of  space
within the Premises, including but not limited to any amendments,
consents  to  assignment, sublet, releases  or  modifications  to
leases  or  guarantees  of  lease  or  easements  affecting   the
Premises, on behalf of ▇. ▇▇▇▇▇▇▇▇▇▇. As long as Fund XX owns  an
interest in the Premises, only Fund XX may obligate ▇. ▇▇▇▇▇▇▇▇▇▇
with respect to any expense for the Premises.
As  further  set forth in paragraph 2 hereof, Fund XX  agrees  to
require  any lessee of the Premises to name ▇. ▇▇▇▇▇▇▇▇▇▇  as  an
insured  or additional insured in all insurance policies provided
for, or contemplated by, any lease on the Premises. Fund XX shall
use its best efforts to obtain endorsements adding Co-Tenants  to
said  policies from lessee within 30 days of commencement of this
agreement.  In any event, Fund XX shall distribute any  insurance
proceeds it may receive, to the extent consistent with any  lease
on  the  Premises,  to  the Co-Tenants  in  proportion  to  their
respective ownership of the Premises.
2.    Income and expenses shall be allocated among the Co-Tenants
in  proportion to their respective share(s) of ownership.  Shares
of  net income shall be pro-rated for any partial calendar  years
included  within the term of this Agreement. Fund XX  may  offset
Co-Tenant Initial: /s/ BEM
Co-Tenancy Agreement for Champps Americana Restaurant, Schaumburg, IL
against,  pay  to itself and deduct from any payment  due  to  ▇.
▇▇▇▇▇▇▇▇▇▇ under this Agreement, and may pay to itself the amount
of  B.  Meierjohan's  share  of any reasonable  expenses  of  the
Premises  which are not paid by ▇. ▇▇▇▇▇▇▇▇▇▇ to Fund XX  or  its
assigns,  within ten (10) days after demand by Fund  XX.  In  the
event there is insufficient operating income from which to deduct
B.  Meierjohan's unpaid share of operating expenses, Fund XX  may
pursue any and all legal remedies for collection.
Operating  Expenses  shall include all normal operating  expense,
including  but not limited to: maintenance, utilities,  supplies,
labor, management, advertising and promotional expenses, salaries
and wages of rental and management personnel, leasing commissions
to  third  parties, a monthly accrual to pay insurance  premiums,
real  estate taxes, installments of special assessments  and  for
structural repairs and replacements, management fees, legal  fees
and accounting fees, but excluding all operating expenses paid by
tenant under terms of any lease agreement of the Premises.
▇. ▇▇▇▇▇▇▇▇▇▇ has no requirement to, but has, nonetheless elected
to  retain,  and  agrees to annually reimburse, Fund  XX  in  the
amount of $678 for the expenses, direct and indirect, incurred by
Fund XX in providing ▇. ▇▇▇▇▇▇▇▇▇▇ with quarterly accounting  and
distributions  of  ▇. ▇▇▇▇▇▇▇▇▇▇`s share of net  income  and  for
tracking,   reporting  and  assessing  the  calculation   of   ▇.
▇▇▇▇▇▇▇▇▇▇`s  share  of  operating  expenses  incurred  from  the
Premises.  This  invoice amount shall be  pro-rated  for  partial
years and ▇.  ▇▇▇▇▇▇▇▇▇▇ authorizes Fund XX to deduct such amount
from  ▇.  ▇▇▇▇▇▇▇▇▇▇`s  share of revenue from  the  Premises.  ▇.
▇▇▇▇▇▇▇▇▇▇  may  terminate  this  agreement  in  this   paragraph
respecting  accounting and distributions at any time and  attempt
to  collect its share of rental income directly from the  tenant;
however, enforcement of all other provisions of the lease remains
the sole right of Fund XX pursuant to Section 1 hereof.  Fund  XX
may  terminate its obligation under this paragraph upon  30  days
notice  to  ▇.  ▇▇▇▇▇▇▇▇▇▇ prior to the end of  each  anniversary
hereof, unless agreed in writing to the contrary.
3.    Full, accurate and complete books of account shall be  kept
in  accordance  with generally accepted accounting principles  at
Fund  XX's principal office, and each Co-Tenant shall have access
to  such  books and may inspect and copy any part thereof  during
normal  business hours. Within ninety (90) days after the end  of
each  calendar year during the term hereof, Fund XX shall prepare
an  accurate  income statement for the ownership of the  Premises
for  said calendar year and shall furnish copies of the  same  to
all  Co-Tenants. Quarterly, as its share, ▇. ▇▇▇▇▇▇▇▇▇▇ shall  be
entitled  to  receive 2.1199% of all items of income and  expense
generated  by the Premises.  Upon receipt of said accounting,  if
the   payments  received  by  each  Co-Tenant  pursuant  to  this
Paragraph  3  do not equal, in the aggregate, the  amounts  which
each  are  entitled  to  receive proportional  to  its  share  of
ownership  with  respect  to  said  calendar  year  pursuant   to
Paragraph  2 hereof, an appropriate adjustment shall be  made  so
that each Co-Tenant receives the amount to which it is entitled.
4.    If  Net Income from the Premises is less than $0.00  (i.e.,
the  Premises  operates  at a loss), or if capital  improvements,
repairs, and/or replacements, for which adequate reserves do  not
exist,  need  to  be made to the Premises, the  Co-Tenants,  upon
receipt of a written request therefor from Fund XX, shall, within
fifteen  (15) business days after receipt of notice, make payment
Co-Tenant Initial: /s/ BEM
Co-Tenancy Agreement for Champps Americana Restaurant, Schaumburg, IL
to  Fund  XX sufficient to pay said net operating losses  and  to
provide necessary operating capital for the premises and  to  pay
for  said capital improvements, repairs and/or replacements,  all
in  proportion  to  their  undivided  interests  in  and  to  the
Premises.
5.    Co-Tenants  may, at any time, sell, finance,  or  otherwise
create  a lien upon their interest in the Premises but only  upon
their  interest  and not upon any part of the interest  held,  or
owned, by any other Co-Tenant.  All Co-Tenants reserve the  right
to escrow proceeds from a sale of their interests in the Premises
to obtain tax deferral by the purchase of replacement property.
6.    If any Co-Tenant shall be in default with respect to any of
its  obligations hereunder, and if said default is not  corrected
within  thirty  (30)  days after receipt by said  defaulting  Co-
Tenant  of written notice of said default, or within a reasonable
period  if  said default does not consist solely of a failure  to
pay money, the remaining Co-Tenant(s) may resort to any available
remedy to cure said default at law, in equity, or by statute.
7.    This Co-Tenancy agreement shall continue in full force  and
effect  and shall bind and inure to the benefit of the  Co-Tenant
and  their respective heirs, executors, administrators,  personal
representatives, successors and permitted assigns until  December
31,  2027  or upon the sale of the entire Premises in  accordance
with  the  terms hereof and proper disbursement of  the  proceeds
thereof,   whichever  shall  first  occur.   Unless  specifically
identified  as  a  personal contract right or obligation  herein,
this  agreement shall run with any interest in the  Property  and
with  the  title thereto. Once any person, party  or  entity  has
ceased  to  have an interest in fee in any portion of the  Entire
Property,  it  shall not be bound by, subject to or benefit  from
the  terms  hereof;  but  its  heirs, executors,  administrators,
personal representatives, successors or assigns, as the case  may
be, shall be substituted for it hereunder.
8.    Any notice or election required or permitted to be given or
served by any party hereto to, or upon any other, shall be  given
to  all known Co-Tenants and deemed given or served in accordance
with  the  provisions  of  this  Agreement,  if  said  notice  or
elections addressed as follows;
