          C.   In accordance with the terms and conditions set

          Buyer, and Buyer wishes to purchase from Seller, all
          of  Seller's right, title and interest  in,  to  and
          under  the  Property,  the  building,  fixtures  and
          improvements thereon and any personal or  intangible
          property related thereto.

NOW, THEREFORE, the parties do hereby agree as follows:

     1.   DESCRIPTION:

          Seller is the owner of all right, title and interest
          in  and all the property located at 4460 32nd Avenue
          South,  City of Grand Forks, County of Grand  Forks,
          State   of   North  Dakota;  and  more  particularly

               Lot  1,  Block 1, Johnson's West  First
               Addition,
               City  of Grand Forks,      Grand  Forks
               County, North Dakota

          The  conveyance shall include all easements, rights,

          any   streets,  roadways,  alleys,  sidewalks,  both
          public  and  private, adjacent  to  the  above  real
          estate (hereinafter collectively referred to as  the
          "Property").

     2.   PURCHASE PRICE:

           The  Purchase Price for the Property is Two Million
Seven   Hundred   Sixty-Six  Thousand   and   No/100   Dollars
($2,766,000); payable as follows:

           A.    Within five (5) days after the Effective Date
of  this  Agreement, Buyer shall deposit Twenty-Five  Thousand
Dollars ($25,000) (the "Earnest Money") in an interest bearing
account  with  First  American Title Insurance  Company,  1900
Midwest  Plaza West, 801 Nicollet Mall, Minneapolis,  MN  (the
"Closing  Agent" or "Title Company"), which shall be  held  in
trust  pending the closing of the transaction contemplated  by
this Agreement.

          If for any reason this Agreement is terminated prior
to  the  expiration  of  the Due Diligence  Period,  then  the
Earnest  Money  and  any  interest accrued  thereon  shall  be
immediately   returned   to   Buyer.    If   the   transaction
contemplated  hereby proceeds to closing,  the  Earnest  Money
shall  be paid to Seller at closing and Buyer shall receive  a
credit  against  the Purchase Price payable hereunder  in  the
amount of the Earnest Money plus interest accrued thereon.  If
the  Buyer  does  not  terminate this Agreement  as  expressly
allowed  hereunder,  the  Earnest Money  shall  thereafter  be
deemed  non-refundable,  except  to  the  extent  any  of  the
contingencies  to  Buyer's  performance  hereunder  (including
without  limitation, Seller's performance of  its  obligations
hereunder) shall not be satisfied.

          B.   The balance of the Purchase Price in cash is to
be  deposited by Buyer into an escrow account with the Closing
Agent on or before the Closing Date (as defined below).


      3.    DUE  DILIGENCE,  CLOSING, DISPOSITION  OF  EARNEST
MONEY:

          A.    Subject  to  the terms provided  below,  Buyer
shall have until no later than forty-five (45) days after  the
Document  Delivery Date (as defined below) (but not less  than
thirty   (30)  days  after  Buyer's  actual  receipt  of   any
information or documents that Buyer shall undertake to  update
as  further set forth in to this Agreement) to conduct its due
diligence of the Property (the "Due Diligence Period").

          B.      The  parties  hereto  may  extend  the   Due
Diligence Period by written agreement.

          C.    If Buyer does not send Seller notification  of
Buyer's satisfaction of its due diligence contingency by 11:59
p.m. CST of the last date of the Due Diligence Period, as such
may  be extended under the terms of this Agreement, then  this
Agreement  shall expire and have no further force and  effect;
and all Earnest Money, including any interest accrued thereon,
shall be returned to Buyer.

          In  the event Buyer does give notice of satisfaction
of its due diligence contingency, then the closing date of the
Property  shall occur no later than ten (10) days after  Buyer
has provided Seller with notice of satisfaction of Buyer's due
diligence  contingency  (the  "Closing  Date"),  provided   no
materially  adverse  change  to  the  Property  Documents  has
occurred.   If  a  materially adverse change to  the  Property
Documents  has  occurred,  Buyer shall  be  allowed  five  (5)
business  days  to  review  and approve  such  changes  or  to
terminate  this Agreement, and upon such termination,  receive
immediate  return of the Earnest Money together with  interest
thereon.

returned   to   Buyer  or  (b)  reduce  the   purchase   price
corresponding  to  a  reduction in the cap  rate  of  5  basis

limited          to,         the         OFAC         website,
(http://www.treas.gov/offices/enforcement/ofac/sdn/t11sdn.pdf)
;   (iii)   who  commits,  threatens  to  commit  or  supports

any  business, nor engage in any transaction or dealing,  with
any  Prohibited  Person, including, but not  limited  to,  the
making  or  receiving of any contribution of funds, goods,  or

(B)  engage  in or conspire to engage in any transaction  that

or  attempts to violate, any of the prohibitions set forth  in

hereof.  Seller shall further have the on-going obligation  up
through  the  Closing Date to inform Buyer in writing  of  any
defect  in  the Improvements that occur between the  Effective

notice  to  Buyer of any defect in the Improvements  shall  be
considered for purposes herein to be an adverse change in  the
Property Documents.

          K.    To Seller's knowledge, Seller has disclosed to
Buyer  all  information relating to the  Property  that  could
reasonably  be expected to have a material adverse  effect  on
the Property.

     If the Seller subsequently becomes aware of the fact that
any  of the representations and warranties made herein  is  no
longer  accurate,  then the Seller shall immediately  disclose
same  in  writing to the Buyer.    Seller's written notice  to
Buyer  of any inaccuracy in the representations and warranties
made herein shall be considered to be an adverse change to the
Property    Documents.    Each   of   the    warranties    and
representations contained in this Section and  other  Sections
of  this Agreement shall be deemed made as of the date of this
Agreement and again as of the Closing Date.

     Seller shall indemnify Buyer, its successors and assigns,
against,  and  shall hold Buyer, its successors  and  assigns,
harmless from, any costs, expenses or damages of any  kind  or
nature, including reasonable attorneys' fees, which Buyer  may

warranties  herein  contained, whether incurred  prior  to  or
after  the Closing Date.  All warranties, representations  and
indemnifications  contained in this  Agreement  shall  survive
Closing.

products  including gasoline, fuel oil, crude oil and  various
constituents  of such products, or any hazardous substance  as
defined    in   the   Comprehensive   Environmental   Response
Compensation and Liability Act of 1980 ("CERCLA"),  42  U.S.C.
9601-9657,  as  amended)  ("Hazardous  Materials")  have  been
generated,  treated,  stored,  released  or  disposed  of,  or
otherwise  placed, deposited in or located on the Property  by
Seller  or by any lessee, agent, employee, licensee or invitee
of Seller nor has any activity been undertaken on the Property
by  Seller  or  by  any lessee, agent, employee,  licensee  or
invitee  of Seller that would cause or contribute to  (a)  the
Property  to become a treatment, storage or disposal  facility
within  the meaning of, or otherwise bring the Property within
the  ambit of, the Resource Conservation and Recovery  Act  of
1976  ("RCRA"), 42 U.S.C. 6901 et seq., or any  similar  state
law or local ordinance, (b) a release or threatened release of
toxic  or  hazardous  wastes  or  substances,  pollutants   or
contaminants,  from  the Property within the  meaning  of,  or
otherwise  bring the Property within the ambit of, CERCLA,  or
any similar state law or local ordinance, or (c) the discharge
of  pollutants or effluents into any water source  or  system,

seq.,  or the Clean Air Act, 42 U.S.C., 7401 et seq.,  or  any
similar  state law or local ordinance.  To the best  knowledge
of  Seller after due inquiry by Seller, neither Seller nor any
lessee,  agent, employee, licensee or invitee  of  Seller  has
introduced any substances or conditions in or on the  Property
that may support a claim or cause of action under RCRA, CERCLA
or  any  other federal, state or local environmental statutes,
regulations,  ordinances  or  other  environmental  regulatory
requirements.   To  the best knowledge  of  Seller  after  due
inquiry  by Seller, no above ground or underground tanks,  are
located  in or about the Property or have been located  under,
in or about the Property and have subsequently been removed or
filled.

       Seller  further  warrants  that  Seller  has  not  been
informed,  advised  or  notified, of any  Hazardous  Materials
including  the use of above or underground storage  tanks  on,
under or about the Property.

          B.    In  the  event  that  Hazardous  Materials  as
defined  herein  are found or suspected to be present  on  the
Property, or other circumstances as set forth in the preceding
section  exist, then Buyer may terminate this  Agreement.   If
Buyer does not elect to terminate, then Seller shall remove or
otherwise  remediate any Hazardous Materials on or  under  the
Property and/or rectify any other condition set forth  in  the
preceding  section to Buyer's satisfaction within thirty  (30)
days after receipt of notice from Buyer that the contingencies
have  been  satisfied.  The Closing shall be delayed  for  the
period  necessary for Seller to comply with the terms of  this
section.

              the Seller for the Property.  Buyer shall, at its sole
              expense, be responsible for obtaining an updated Phase I
              environmental report and shall have until the end of the Due
              Diligence Period to review and approve of the same (the
              "Updated Phase I Report");


          C.    Buyer shall be allowed up to the latter of the
end  of  the  Due Diligence Period or thirty (30)  days  after
receipt  of  the  Updated Title Commitment and  Updated  Title
Commitment  Documents,  Updated Phase  I  Report  and  Updated
Survey  (and  five  (5)  business days  from  receipt  of  any
subsequent   update  or  endorsement  to  the  Updated   Title
Commitment  occurring  after the date  of  the  Updated  Title
Commitment  to be delivered by Seller adding new or additional
requirements or exceptions thereto) to make any objections, in
Buyer's  sole discretion, to the Title Commitment  or  matters
not  previously  reflected  on the  ALTA  Survey  or  Phase  I
Environmental  Report  of previous date  supplied  by  Seller.
Objections are to be made in writing or are to be deemed to be
waived.

          If  any objections are made, Seller shall be allowed
thirty  (30)  days to correct such objections.  In  the  event
Seller  is unable to cure such objections within this  period,
Buyer shall have the option to either (1) acquire the Property
subject  to such objections, lien, encumbrance or other  title
defect at Buyer's discretion, with a right to deduct from  the
Purchase Price amounts required to clear any title defects; or
(2)  rescind this Agreement, in which latter event the Earnest
Money  herein paid, together with all interest earned thereon,
shall be immediately refunded to Buyer.

          D.   Closing  Documents.   At least seven  (7)  days
prior to the end of the Due Diligence Period, Seller shall, at
its  sole  expense, provide to Buyer the following  documents,
and  Seller and Buyer shall agree, prior to the end of the Due
Diligence Period, on the form of the following documents to be
delivered to Buyer on the Closing Date by Seller as set  forth
in Section 9  hereof:

     (a)  Limited or special warranty deed;

     (b)  Seller's Affidavit;

     (c)  FIRPTA Affidavit;

     (d)  Assignment and Assumption of the Lease in  the  form
          attached hereto and incorporated herein as Exhibit "A";

     (e)  A  generic Assignment of warranties in the  form  as
          attached hereto and incorporated herein as Exhibit "B"; and

     (f)  A tenant estoppel certificate substantially in the form
          (if any) as contemplated by the Lease that shall include
          confirmation that tenant pays real estate taxes  based upon
          what is assessed during the lease year or is due and payable
          during the lease year.  If the form of Tenant estoppel
          certificate is not prescribed by the Lease and Buyer submits
          to Seller the form of estoppel certificate (as the case may
          be) preferred by Buyer or required by Buyer's Lender (if any)
          prior to the expiration of the Due Diligence Period, Seller
          will submit such form of estoppel certificate to Tenant.

     In  the  event that Seller and Buyer do not reach  mutual
agreement  on  the form of the above described  documents  (a)
through (f) prior to the end of the Due Diligence Period, this
Agreement may be terminated by either Seller or Buyer and  the
Earnest  Money and accrued interest shall be returned in  full
to  the  Buyer  immediately and neither party shall  have  any
further duties or obligations to the other hereunder.


     7.   EXAMINATION OF PROPERTY:

          It  is  expressly understood by Seller that,  during
the  term  of  this  Agreement, Buyer   intends  to  undertake
preliminary investigation for the development of the Property,
as follows:

          A.    From and after the date hereof, Buyer, and its
representatives,  shall  have the  right  to  enter  upon  the
Property  for the purpose of surveying, conducting soil  tests
thereon, and making such other physical inspection thereof  as
Buyer deems necessary or appropriate; provided, however,  that
in  the course of such activities, Buyer shall make no visible
improvements  to  or  changes in the  property  prior  to  the
Closing  Date,  and  shall repair any  damage  or  disturbance
caused  by  Buyer's  activities.   Any  inspection  of   Buyer
pursuant to this section shall not be construed so as to waive
or limit any of Buyer's rights or remedies hereunder.

          B.    Buyer  hereby  agrees to hold Seller  harmless
from liabilities that may arise out of Buyer's presence on the
Property prior to the Closing Date.



     8.   TAXES, PRORATIONS AND CLOSING COSTS:

           A.    Real  Estate Taxes and Assessments.    On  or
before  the  Closing Date, Seller shall pay  all  real  estate
taxes  and installments of special assessments payable in  all
years prior to the year of Closing.  All real estate taxes for
due and payable in the year of Closing shall be prorated as of
the Closing Date.

           Seller shall pay all special assessments if  levied
or  pending  as of the Closing Date including all installments
of  special  assessments for the year of Closing or subsequent
years.   For  purposes of this Agreement, a "pending"  special
assessment means any work or project which, as of the  Closing
Date,  has  been  directed or authorized by  any  governmental
authority,  the cost of which will be, but has  not  yet  been
certified  to and included in the real property taxes  payable
with respect to the Property.  "Special assessments" does  not
include  the general tax levy of Special Improvement Districts
which shall be treated as real estate taxes.

           Seller represents to Buyer that to the best of  its
knowledge,  all real estate taxes and installments of  special
assessments  due  and payable prior to  and  in  the  year  of
Closing  on  or before the Closing Date have been or  will  be
paid in full as of the Closing Date.  It is understood between
Seller  and  Buyer that all unpaid levied and pending  special
assessments  payable in the year of Closing are  paid  by  the
Tenant and shall be the responsibility of the Tenant under the
Lease  after  the Closing Date.  Seller further represents  to
Buyer  that  Tenant  shall pay a pro-rata share  of  all  real
estate  taxes and installments of special assessments due  and
payable in the year of Closing.

             In  the  event  Tenant does not pay  any  special
assessments  or  real estate taxes that are the responsibility
of the Tenant under the Lease, Seller and Buyer agreed to each
pay  its prorata share of said assessments or taxes as of  the
Closing Date.

The provisions of this paragraph 8 shall survive Closing.


           B.    Prorations.  The Buyer and the Seller, as  of
the  Closing Date, shall prorate: (i) all rent due  under  the
Lease, if any, (ii) ad valorem taxes, personal property taxes,
charges  or assignments affecting the Property (on a  calendar
year  basis),  (iii)  utility charges, including  charges  for
water,  gas,  electricity,  and  sewer,  if  any,  (iv)  other
expenses relating to the Property which have accrued  but  not
paid  as  of  the  Closing Date, based upon the  most  current
ascertainable tax bill and other relevant billing information,
including any charges arising under any of the encumbrances to
the  Property.   (Provided, however, no adjustments  shall  be
made  at  closing for items payable by the tenant, or  payable
between  the  parties  hereto thereafter,  unless  the  tenant
ultimately  does  not  pay  the same.)   To  the  extent  that
information  for  any such proration is not available  on  the
Closing Date or if the actual amount of such taxes, charges or
expenses  differs  from the amount used in the  prorations  at
closing, then the parties shall make any adjustments necessary
so  that the prorations at closing are adjusted based upon the
actual amount of such taxes, charges or expenses.  The parties
agree to make such reprorations as soon as possible after  the
actual  amount  of  real  estate taxes,  charges  or  expenses
prorated  at  closing becomes available.  In the event  Tenant
does  not pay any expenses that are the responsibility of  the
Tenant  under the Lease, Seller and Buyer agreed to  each  pay
its  prorata  share of said assessments or  taxes  as  of  the
Closing  Date.  This provision and the respective  obligations
of the parties shall survive Closing.

          C.   Closing Costs.   Seller and Buyer shall pay one-
half  of  the following costs of closing, including,  but  not
limited to, all escrow fees of Buyer and Seller.

          Seller  shall pay the following costs:  any and  all
brokerage  commissions owed by Seller to Duemelands Commercial
LLLP,  any  and  all costs associated with the  updated  title
commitment/search, all costs associated with the Owner's Title
policy premium, any and all costs associated with recording of
the  Deed and Assignment and Assumption of Lease, as  well  as
any  costs  associated with any document(s)  or  instrument(s)
necessary  to cure any title objections raised by  Buyer,  the
transfer  taxes (state, county and municipality,  if  such  is
required) and/or transfer fees.

          Buyer  shall  pay any and all costs associated  with
any  special endorsements it may require on its Owner's  Title
Policy,  except  the  costs associated  with  any  endorsement
required to cure Buyer's objection to the existing matters  of
title or survey..

Each  party  will pay its own attorneys' fees  to  close  this
transaction.

          E.   Any escrow closing fee shall be paid equally by
Buyer  and Seller.  Seller shall pay the premium for the Title
Policy  in favor of Buyer in the amount of the Purchase  Price
issued  at  or  after the Closing by the Title Company.   Each
party shall pay its attorneys' fees.

and such default continues for a period of ten (10) days after
written notice, then the retention of the earnest money  shall
be  Seller's exclusive remedy hereunder and said monies  shall
be   deemed liquidated damages.  The parties hereto agree that
such  liquidated  damages  are not a  penalty,  but  represent
actual  damages Seller will sustain upon any default by Buyer,
which  damages will be substantial but are extremely difficult
to ascertain.

            B.     In  the  event  Seller  defaults  upon  its

the  Property for any reason except the default of Buyer,  and

written notice, Buyer may terminate this Agreement and receive
return  of  its Earnest Money, or enforce specific performance
