NOW THEREFORE, in consideration of the purchase by Ainslie 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 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

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

respect to any expense for the Premises.

Co-Tenancy Agreement for Tractor Supply Company, Bristol, VA



As  further set forth in paragraph 2 hereof, Fund XVIII agrees to
require  any Tenant of the Premises to name Ainslie 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  Tenant  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,  expenses and any net proceeds from a sale  of  the
Premises 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 Ainslie  under  this
Agreement, and may pay to itself the amount of Ainslie's share of
any  legitimate expenses of the Premises which are  not  paid  by
Ainslie 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 Ainslie'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.

Ainslie  has no requirement to, but has, nonetheless  elected  to
retain,  and  agrees to annually reimburse,  Fund  XVIII  in  the
amount of $874 for the expenses, direct and indirect, incurred by
Fund  XVIII  in  providing Ainslie with quarterly accounting  and
distributions of Ainslie's share of net income and for  tracking,
reporting  and  assessing the calculation of Ainslie's  share  of
operating  expenses  incurred from  the  Premises.  This  invoice
amount   shall  be  pro-rated  for  partial  years  and   Ainslie
authorizes Fund XVIII to deduct such amount from Ainslie's  share
of  revenue  from  the  Premises.   Ainslie  may  terminate  this
agreement  respecting quarterly accounting and  distributions  in
this  paragraph  at  any time and seek 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
XVIII pursuant to section 1 hereof.  Fund XVIII may terminate its
obligation  under this paragraph upon 30 days notice  to  Ainslie
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  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,  Ainslie
shall be entitled to receive 18.4736% 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 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-Tenant Initial: /s/ EEA
Co-Tenancy Agreement for Tractor Supply Company, Bristol, VA





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 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,  or
set forth herein.

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
April  10,  2020  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 any  poortion
of  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.  Ainslie  agrees  to
notify  Fund XVIII upon the appointment of any successor trustee,
or any amendment of the Ainslie Loving Trust affecting the powers
of  the  Trustees  to  manage or dispose of the  Ainslie  Trust's
interest in the Premises.
