Tankenoff With Copy to: Maun & Simon, PLC 2000 Midwest Plaza Building West 801 Nicollet Mall Minneapolis, Minnesota 55402 Attention: Charles Bans To Buyer: R & D Systems, Inc. 614 McKinley Place Minneapolis, MN 55413 Attention: Tom Oland, CEO With Copy to: Fredrikson & Byron, P.A. 900 Second Ave. S Suite 1100 Minneapolis, MN 55402 Attention: Chuck Diessner Rejection or refusal to accept or the inability to deliver notice hereunder because of changed address of which no notice was given shall be deemed to be receipt of the notice, demand or request. Any party shall have the right from time to time and at any time upon at least ten (10) days' written notice thereof, to change their respective addresses, and each shall have the right to specify as its address any other address within the United States of America. SECTION XVI CONDEMNATION In the event any portion of the Property is condemned or access thereto shall be taken, or in either case threatened, prior to the closing, and the taking renders the Property remaining unsuitable for the Buyer's current and/or anticipated use of the Property and Buyer notifies Seller in writing that it wishes to terminate this Purchase Agreement within thirty (30) days after written notice to Buyer of such condemnation action, then this Purchase Agreement shall terminate, neither party to this Agreement shall have any further liability to the other parties (except for Buyer's indemnity in Section IV(a) hereof), and the Deposit (exclusive of any interest earned thereon) shall be returned to Buyer. If the Purchase Agreement is not terminated pursuant to the preceding sentence, the Purchase Price of the Property shall not be affected, it being agreed that if the award is paid prior to the closing of this transaction, such amount, insofar as it pertains to the Property, shall be held in escrow and delivered to Buyer at the time of closing; and if the award has not been paid prior to the closing of this transaction, then at the closing Seller shall assign to Buyer all of its right, title and interest with respect to such award and shall further execute any other instrument requested by Buyer to assure that such award is paid to Buyer. If Buyer fails to timely close the transaction and this agreement is terminated by Seller, any escrowed condemnation proceeds will be paid to Seller. If Buyer does not terminate this Purchase Agreement, it shall have the right to contest the condemnation and/or the award resulting therefrom but such right shall terminate if Seller terminates this Purchase Agreement as a result of Buyer's default hereunder. If this Purchase Agreement is not terminated, the parties shall cooperate in defending any such taking and/or maximizing the amount of the award. Neither party will take any action relating to the taking, without the other party's written consent prior to closing. SECTION XVII DAMAGE OCCURRING PRIOR TO CLOSING If, prior to the closing date, all or any part of the Property is substantially damaged by fire, casualty, the elements or any other cause, Seller shall immediately give notice to Buyer of such fact and at Buyer's option (to be exercised with thirty (30) days after Seller's notice), this Purchase Agreement shall terminate, in which event neither party will have any further obligations under this Purchase Agreement and the Deposit (exclusive of any interest earned thereon) shall be returned to Buyer. If Buyer fails to elect to terminate despite such damage, Seller (whether the damage is "substantial" or not) to the extent reasonably possible shall promptly commence to repair such damage or destruction to the Property's prior condition and to mitigate further damages using the quality of materials and workmanship existing prior to the date of the casualty. If such damage shall be completely repaired prior to the closing date, then there shall be no reduction in the Purchase Price and Seller shall retain the proceeds of all insurance related to such damage. If such damage shall not be completely repaired prior to the closing date, at Buyer's election, (i) Seller shall assign to Buyer all right to receive the proceeds of all insurance related to such damage, less costs incurred by Seller in mitigating damage or making repairs that are reimbursable by insurance then in force, and the Purchase Price shall remain the same, or (ii) the closing shall be postponed pending complete restoration of the damage by Seller. For purposes of this Section, the words "substantially damaged" means damage that would cost $7,000,000.00 or more to repair. SECTION XVIII LICENSE AGREEMENT AND PARKING EASEMENT Seller, or its successor, ("Licensor") and Buyer agree to enter into a written license agreement at closing, under which Seller agrees to license to Buyer parking spaces (the "Licensed Real Property") in a form to be hereafter agreed to. At closing, Seller shall grant Buyer a parking easement in a form to be hereafter agreed to providing for the parking of up to 110 vehicles over part of the north one-half of the parking area commonly known as the MT-BN lot. SECTION XIX MERGER/BINDING AGREEMENT All previous negotiations and understandings between Seller and Buyer or their respective agents and employees with respect to the transactions set forth herein are merged in this Purchase Agreement which alone fully and completely express the parties' rights, duties and obligations. This Purchase Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors, assigns, heirs and personal representatives. SECTION XX EFFECTIVE DATE The Effective Date of this Purchase Agreement shall be the date of the last party's execution; provided, however, that if the last party does not execute this Purchase Agreement and deliver a duly executed counterpart of the same to the first signing party within three (3) days of the first party's execution date, then the offer or commitment to be bound hereby by the first executing party shall automatically be revoked and withdrawn, whereupon neither party shall be bound hereto. SECTION XXI GOVERNING LAW This Purchase Agreement shall be deemed to be a contract made under the laws of the State of Minnesota and for all purposes shall be governed and construed in accordance with the laws of said State. SECTION XXII ASSIGNMENT Buyer shall have the right to assign at closing its interest in this Purchase Agreement to a third party, provided that assignee becomes personally responsible for Buyer's obligations herein. SECTION XXIII CONDITIONS PRECEDENT FOR BOTH SELLER AND BUYER Notwithstanding any other provision hereof to the contrary, this Purchase Agreement, including, but not limited to, Section VIII hereof, shall be null and void and neither party shall hereafter be liable to the other unless (a) prior to February 5, 1999, both Seller and Buyer have executed the 2101 Kennedy Option and the Phase II Option; (b) prior to January 29, 1999, Buyer has delivered to Title the tenant estoppel letter required by Section VIII and Buyer's Board of Directors approves the execution of this Purchase Agreement and Buyer delivers a written copy of such resolution to Seller; and (c) prior to February 5, 1999, Buyer and Seller have agreed to the form and substance of the License Agreement, the Parking Easement and the Management Agreement as defined in Sections XVIII and XXV. SECTION XXIV PREPAID EXPENSES Buyer and/or its assignee agrees to pay to Seller, following the closing on a monthly basis, the amounts described in Exhibit B hereto attached representing certain prepaid expense items previously paid by Seller. The obligations of Buyer and/or its assignee under this Section XXIV shall survive the closing. SECTION XXV MANAGEMENT CONTRACT At the closing, Buyer and Seller shall enter into a management contract in the form to be hereafter agreed to covering (i) the Property, (ii) the property covered by the 2101 Kennedy Option, effective upon the Buyer and/or its assignee's acquisition of fee title to the same and (iii) the property covered by the Phase II Option effective upon the Buyer and/or its assignee's acquisition of fee title to the same. The initial management annual fee measured on a calendar year basis shall be $213,250.00 for calendar year 1999 (and shall be prorated for calendar year 1999) and shall increase to $250,000.00 when Buyer acquires the property subject to the 2101 Kennedy Option and shall increase by two percent for every year thereafter until the acquisition of fee title to 2001 Kennedy pursuant to the Phase II Option when the annual management fee shall increase to $335,000.00 and then increase by two percent (2%) per year thereafter. The management fee shall include Seller's marketing expenses for leasing 2101 Kennedy and 2001 Kennedy but shall not include any broker's fees. Either party may terminate the management contract upon one hundred eighty (180) days prior written notice to the other but such termination shall not affect any liabilities which accrue prior to the effective date of termination. IN WITNESS WHEREOF, the parties hereto have executed these presents intending to be bound by the provisions herein contained. SELLER: BUYER: Hillcrest Development R & D Systems, Inc.
