         termination of this Agreement, Seller shall not create, suffer or
         assume any new or additional encumbrances on title to the Real Property
         (other than mechanic's liens in the ordinary course of tenant
         improvements provided for under the Leases) without Purchaser's
         consent, which consent Purchaser may grant or withhold in Purchaser's
         sole discretion.

                  7.1.6 To Seller's knowledge, there are no underground or above
         ground storage tanks of any size or type located on the Real Property.


                  7.1.7 Seller has not entered into any other contracts for the
         sale of the Real Property nor are there any rights of first refusal to
         purchase or other options to purchase the Real Property available to
         any third parties.

                  Whenever herein a representation is made based upon the
         knowledge of Seller, such knowledge is limited to the actual knowledge
         of Bill Kullback. Seller represents that Bill Kullback is familiar with
         and has first-hand knowledge of conditions at the Property. In the
         event any of the representations and warranties contained herein become
         untrue as of the Closing Date as a result of information received by
         Seller or occurrences subsequent to the date hereof or otherwise,
         Seller shall promptly so notify Purchaser in writing. Except as
         provided below, Seller will indemnify, defend and hold harmless
         Purchaser, its successors and assigns, from any loss, claim, damage or
         expense, including reasonable attorneys' fees, that Purchaser, its
         successors and assigns, incurs because of the breach of any of the
         above representations and warranties, whether such breach is discovered
         before or after the Closing Date.

                                      -8-


                  Notwithstanding anything to the contrary herein, the effect of
         the representations and warranties made in this Agreement shall not be
         diminished, abrogated or deemed to be waived by any assessments,
         inspections or investigations made by Purchaser; provided, however, if
         through the delivery to Purchaser of written information from a)
         Seller; or b) from any third party engaged by Purchaser in order to
         perform any of the tests, studies, investigations and inspections
         contemplated under this Agreement, prior to Closing, Purchaser receives
         evidence that would provide reasonable grounds to a qualified person to
         believe that any of the Seller's representations and warranties made in
         this Agreement, or any documents that Seller actually delivers to
         Purchaser at Closing, pursuant to the provisions of this Agreement, are
         or may be untrue, and Purchaser nevertheless elects to close under this
         Agreement, then Purchaser shall be deemed to have waived the breach in
         question, and shall have no right, at any time after Closing, to assert
         a claim, of any nature whatsoever, against Seller with respect to that
         breach.

         7.2 Purchaser's Representations and Warranties. Purchaser represents
and warrants to Seller as of the date of this Agreement as follows:

                  7.2.1 Purchaser has been duly formed and is in good standing
         under the laws of the State of Minnesota, is duly qualified to transact
         business in the jurisdiction in the State of Minnesota, and has the
         requisite power and authority to enter into and perform this Agreement
         and the documents and instruments required to be executed and delivered
         by Purchaser pursuant hereto. This Agreement has been duly executed and
         delivered by Purchaser and is a valid and binding obligation of
         Purchaser enforceable in accordance with its terms. This Agreement and
         the documents and instruments required to be executed and delivered by
         Purchaser pursuant hereto have each been duly authorized by all
         necessary partnership action on the part of Purchaser and that such
         execution, delivery and performance does and will not conflict with or
         result in a violation of Purchaser's partnership agreement or any
         judgment, order or decree of any court or arbiter to which Purchaser is
         a party, or any agreement to which Purchaser and/or any of the Property
         is bound or subject.

                  7.2.2 Purchaser has not (i) made a general assignment for the
         benefit of creditors, (ii) filed any involuntary petition in bankruptcy
         or suffered the filing of any involuntary petition by Purchaser's
         creditors, (iii) suffered the appointment of a receiver to take
         possession of all or substantially all of Purchaser's assets, (iv)
         suffered the attachment or other judicial seizure of all, or

         inability to pay its debts as they come due, or (vi) made an offer of

Hazardous Materials Laws. Purchaser takes responsibility and liability for all
obligations attributable to any Hazardous Material in, at, under or about

regarding the presence or absence of any Hazardous Material. Purchaser hereby
acknowledges and agrees that it shall rely solely on the investigations,
information, studies and reports prepared by or through Purchaser, at its sole
cost and expense, with regard to Hazardous Material. Purchaser shall make such
studies and investigations, conduct such tests and surveys, and engage such
specialists as Purchaser deems appropriate to evaluate fairly the Property and
its risks from a Hazardous Material standpoint.

NOT DISCLOSE ALL MATERIAL MATTERS AFFECTING THE PROPERTY. SUBJECT ONLY TO THE
TERMS OF SECTIONS 7.1, 8.2 AND ARTICLES 10 AND 11, PURCHASER AGREES TO ACCEPT
THE PROPERTY IN ITS "AS IS" "WHERE IS" AND "WITH ALL FAULTS" CONDITION AT
