WHEREAS,  The  parties  hereto wish to provide  for  the  orderly
operation  and management of the Premises and Adamson's  interest
by  Fund  XVIII;  the  continued  leasing  of  space  within  the

NOW THEREFORE, in consideration of the purchase by Adamson of  an
undivided  interest  in and to the Premises,  for  at  least  One

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 XVIII, or its designated agent, successors  or
assigns. Provided, however, if Fund XVIII shall sell all  of  its
interest  in  the  Premises, the duties and obligations  of  Fund
XVIII  respecting management of the Premises as set forth herein,
including but not limited to paragraphs 2, 3, and 4 hereof, shall
be exercised by Fund XVIII unless and until Fund XVIII shall sell
all  of  its  interest in the Premises in which event the  duties
respecting management of the Premises 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  XVIII 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. The parties  hereto  hereby
designate  Fund XVIII as their sole and exclusive agent  to  deal
with,  and  Fund XVIII retains the sole right to deal  with,  any
property agent or tenant 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 Adamson. Only Fund
XVIII  may obligate Adamson with respect to any expense  for  the
Premises.   Adamson agrees to direct any inquiry  respecting  the
Premises  or  of  a  tenant in the Premises to  Fund  XVIII,  and
subject  to  the provisions of the last paragraph of  section  2,
shall  not  contact  such tenants without  Fund  XVIII's  written
approval,  as  long  as Fund XVIII retains  an  interest  in  the
Premises.

Co-Tenancy Agreement for Champps, Columbus, OH






As  further set forth in paragraph 2 hereof, Fund XVIII agrees to
require  any lessee of the Premises to name Adamson as an insured
or  additional insured in all insurance policies provided for, or
contemplated by, any lease on the Premises. Fund XVIII 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  XVIII  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 XVIII may offset
against, pay to itself and deduct from any payment due to Adamson
under  this  Agreement,  and may pay  to  itself  the  amount  of
Adamson's share of any legitimate expenses of the Premises  which
are  not paid by Adamson to Fund XVIII or its assigns, within ten
(10)  days  after  demand by Fund XVIII. In the  event  there  is
insufficient  operating  income from which  to  deduct  Adamson's
unpaid share of operating expenses, Fund XVIII 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.

Adamson  has no requirement to, but has, nonetheless  elected  to
retain,  and  agrees to annually reimburse,  Fund  XVIII  in  the
amount of $700 for the expenses, direct and indirect, incurred by
Fund  XVIII  in  providing Adamson with quarterly accounting  and
distributions of Adamson's share of net income and for  tracking,
reporting  and  assessing the calculation of Adamson's  share  of
operating  expenses  incurred from  the  Premises.  This  invoice
amount   shall  be  pro-rated  for  partial  years  and   Adamson
authorizes Fund XVIII to deduct such amount from Adamson's  share
of   revenue  from  the  Premises.  Adamson  may  terminate  this
agreement   in   this   paragraph   respecting   accounting   and
distributions at any time and collect its share of rental  income
directly from the tenant.

3.    Full, accurate and complete books of account shall be  kept
in  accordance  with generally accepted accounting principles  at
Fund  XVIII'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  XVIII
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,  Adamson
shall be entitled to receive 14.1798% 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 XVIII,  shall,
within  fifteen (15) business days after receipt of notice,  make
payment to




Co-Tenant Initial: /s/ GEA /s/ WKA
Co-Tenancy Agreement for Champps, Columbus, OH






Fund  XVIII  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  property management 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
August  29,  2031  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  Premises and with the title thereto. Once any person,  party
or  entity has ceased to have an interest in fee in the Premises,
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 deemed
given  or  served  in  accordance with  the  provisions  of  this
Agreement, if said notice or elections addressed as follows;

and  all  provisions hereof, in all other respects, shall  remain
valid and enforceable.
