WHEREAS,  The  parties  hereto wish to provide  for  the  orderly
operation and management of the Premises and Obata's interest  by
Fund  85-A;  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 Obata  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 85-A, or its designated agent, successors  or
assigns.  Provided, however, if Fund 85-A shall sell all  of  its
interest in the Premises, the duties and obligations of Fund 85-A
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  85-A  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 85-A  as  their  sole  and
exclusive  agent  to deal with, and Fund 85-A  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 85-
A,  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 Obata. As long as  Fund  85-A  owns  an
interest in the Premises, only Fund 85-A may obligate Obata  with
respect to any expense for the Premises.


As  further set forth in paragraph 2 hereof, Fund 85-A agrees  to
require any lessee of the Premises to name Obata as an insured or
additional insured in all insurance policies provided for, or


Co-Tenant Initial: /s/ TSO
Co-Tenancy Agreement for Rio Bravo-St. Paul, MN


contemplated by, any lease on the Premises. Fund 85-A  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 85-A 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 85-A may  offset
against,  pay to itself and deduct from any payment due to  Obata
under this Agreement, and may pay to itself the amount of Obata's
share  of any reasonable expenses of the Premises which  are  not
paid  by Obata to Fund 85-A or its assigns, within ten (10)  days
after  demand  by  Fund 85-A. In the event there is  insufficient
operating  income from which to deduct Obata's  unpaid  share  of
operating  expenses,  Fund  85-A 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.

Obata  has  no  requirement to, but has, nonetheless  elected  to
retain, and agrees to annually reimburse, Fund 85-A in the amount
of  $821 for the expenses, direct and indirect, incurred by  Fund
85-A   in   providing   Obata  with  quarterly   accounting   and
distributions  of Obata's share of net income and  for  tracking,
reporting  and  assessing the calculation  of  Obata's  share  of
operating  expenses  incurred from  the  Premises.  This  invoice
amount  shall be pro-rated for partial years and Obata authorizes
Fund  85-A  to deduct such amount from Obata's share  of  revenue
from  the  Premises. Obata 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 85-A pursuant to Section 1 hereof.
Fund  85-A may terminate its obligation under this paragraph upon
30  days  notice  to Obata 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  85-A'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 85-A 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, Obata shall  be
entitled  to receive 16.0589% 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  85-A,  shall,
within  fifteen (15) business days after receipt of notice,  make
payment to Fund 85-A sufficient to pay said net operating  losses
and to provide necessary operating capital

Co-Tenancy Agreement for Rio Bravo-St. Paul, MN




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,  2026  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
