92   pollution which may be required to be reported to the Wisconsin Department
     of Natural Resources.

     to cure have been repaired in a good and workmanlike manner.

104  May Cause or Threaten to Cause Envirnomental Pollution). Any "Environmental
     site assessment" performed under this Offer shall comply with

     Testing and Materials "Standards for Environmental Site Assessments for

106  Commercial Real Estate"), and state and federal guidelines, as applicable.

     TO CLOSING, A "GAP ENDORSEMENT" TO THE

199  TITLE COMMITMENT OR AN ESCROW CLOSING.

200  - TITLE ACCEPTABLE FOR CLOSING: If title is not acceptable for closing,
     Buyer shall notify Seller in writing of objections to title by the time set
     for closing.

201  In such event, Seller shall have a reasonable time, but not exceeding 15
     days, to remove the objections, and the time for closing shall be
     extend- ed as necessary

202  for this purpose. In the event that Seller is unable to remove the
     objections, Buyer shall have 5 days from receipt of notice thereof, to
     deliver written notice waiving

203  the objections, and the time for closing shall be extended accordingly. If
     Buyer does not waive the objections, this offer shall be null and void.
     Providing title

204  evidence acceptable for closing does not extinguish Seller's obligations to
     give merchantable title to Buyer.

205  DELIVERY/RECEIPT Unless otherwise stated in this Offer, any signed document
     transmitted by facsimile machine (fax) shall be treated in all man-ner

206  and respects as an original document and the signature of any Party upon a
     document transmitted by fax shall be considered an original sig-

207  nature. Personal delivery to, or actual receipt by, any named Buyer or
     Seller constitutes personal delivery to, or actual receipt by Buyer or
     Seller. Once

208  received, a notice cannot be withdrawn by the Party delivering the notice
     without the consent of the Party receiving the notice. A Party may not
     unilaterally

209  reinstate a contingency after a notice of a contingency waiver has been
     received by the other Party. THE DELIVERY/RECEIPT PROVI-SIONS IN THIS OFFER
     MAY

210  BE MODIFIED WHEN APPROPRIATE (E.G., WHEN MAIL DELIVERY IS NOT DESIRABLE
     (SEE LINES 25 - 31)). Buyer and Seller author-ize the agents of Buyer and
     Seller

211  to distribute copies of the Offer to Buyer's lender, appraisers,
     title insurance companies and any other settle- ment service providers for
     the transaction.

212

213  DATES AND DEADLINES Deadlines expressed as a number of "days" from an
     event, such as acceptance, are calculated by excluding the day the event

214  occurred and by counting subsequent calendar days. The deadline expires at
     midnight on the last day. Deadlines expressed as a specific num-ber of
     "business

215  days" exclude Saturdays, Sundays, any legal holiday under Wisconsin or
     Federal law, and other day designated by the President such that the postal
     service

216  does not receive registered mail or make regular deliveries on that day.
     Deadlines expressed as a specific number of "hours" from the occurrence of
     an event, such

217  as receipt of a notice, are calculated from the exact time of the event,
     and by counting 24 hours per calendar day. Deadlines expressed as a
     specific day of the

218  calendar year or as the day of a specific event, such as closing, expire at
     midnight of that day.

219  DEFAULT Seller and Buyer each have the legal duty to use good faith and due
     diligence in completing the terms and conditions of this Offer. A material
     failure

220  to perform any obligation under this Offer is a default which may subject
     the defaulting party to liability for damages or other legal remedies.

221       If Buyer defaults, Seller may:

222       (1) sue for specific performance and request the earnest money as
              partial payment of the purchase price; or

223       (2) terminate the Offer and have the option to: (a) request the
              earnest money as liquidated damages; or (b) direct Broker to
              return the

224           earnest money and have the option to sue for actual damages.

225       If Seller defaults, Buyer may:

226       (1) sue for specific performance; or

227       (2) terminate the Offer and request the return of the earnest money,
              sue for actual damages, or both.

228       In addition, the Parties may seek any other remedies available in law
          or equity.

229  The Parties understand the availability of any judicial remedy will depend
     upon the circumstances of the situation and the discretion of the courts.
     If either

230  Party defaults, the Parties may renegotiate the Offer or seek nonjudicial
     dispute resolution instead of the remedies outlined above. By agreeing to
     binding

231  arbitration, the Parties may lose the right to litigate in court of law
     those disputes covered by the arbitration agreement. NOTE: IF ACCEPTED,
     THIS OFFER

232  CAN CREATE A LEGALLY ENFORCEABLE CONTRACT. BOTH PARTIES SHOULD READ THIS
     DOCUMENT CAREFULLY. BROKERS MAY PROVIDE

233  A GENERAL EXPLANATION OF THE PROVISIONS OF THE OFFER BUT ARE PROHIBITED BY
     LAW FROM GIVING ADVICE OR OPINIONS

234  CONCERNING YOUR LEGAL RIGHTS UNDER THIS OFFER OR HOW TITLE SHOULD BE TAKEN
     AT CLOSING. AN ATTORNEY SHOULD BE


235  CONSULTED IF LEGAL ADVICE IS NEEDED.

236  EARNEST MONEY

237  - HELD BY: Unless otherwise agreed, earnest money shall be paid to and held
     in the trust account of the listing broker (buyer's agent if Property is
     not

238  listed or seller if no broker is involved), until applied to purchase price
     or otherwise disbursed as provided in the Offer. CAUTION: SHOULD PERSONS
     OTHER

239  THAN BROKER HOLD EARNEST MONEY, AN ESCROW AGREEMENT SHOULD BE DRAFTED BY
     THE PARTIES OR AN ATTORNEY. IF SOMEONE OTHER THAN BUYER MAKES

240  PAYMENT OF EARNEST MONEY, CONSIDER A SPECIAL DISBURSEMENT AGREEMENT.

241  - DISBURSEMENT: If negotiations do not result in an accepted offer, the
     earnest money shall be promptly disbursed (after clearance from payor's

242  depository institution if earnest money is paid by check) to the person(s)
     who paid the earnest money. At closing, earnest money shall be disbursed

243  according to the closing statement. If this Offer does not close, the
     earnest money shall be disbursed according to a written disbursement
     agreement signed

244  by all Parties to this Offer (Note: Wis. Adm. Code ss.RL 18.09(1)(b)
     provides that an offer to purchase is not a written disbursement agreement
     pursuant to which

245  the broker may disburse). If the disbursement agreement has not been
     delivered to broker within 60 days after the date set for closing, broker
     may disburse

246  the earnest money: (1) as directed by an attorney who has reviewed the
     transaction and does not represent Buyer or Seller; (2) into a court
     hearing a lawsuit

247  involving the earnest money and all Parties to this Offer; (3) as directed
     by court order; or (4) any other disbursement required or allowed by law.
     Broker may

248  retain legal services to direct disbursement per (1) or to file an
     interpleader action per (2) and broker may deduct from the earnest money
     any costs and

249  reasonable attorneys fees, not to exceed $250, prior to disbursement.

250  - LEGAL RIGHTS/ACTION: Broker's disbursement of earnest money does not
     determine the legal rights of the Parties in relation to this Offer.
     Buyer's

251  or Seller's legal right to earnest money cannot be determined by broker. At
     least 30 days prior to disbursement per (1) or (4) above, broker shall send
     Buyer

252  and Seller notice of the disbursement by certified mail. If Buyer or Seller
     disagree with broker's proposed disbursement, a lawsuit may be filed to
     obtain

253  a court order regarding disbursement. Small Claims Court has jurisdiction
     over all earnest money disputes arising out of the sale of residential
     property with

254  1-4 dwelling units and certain other earnest money disputes. The Buyer and
     Seller should consider consulting attor-neys regarding their legal rights
     under

255  this Offer in case of a dispute. Both Parties agree to hold the broker
     harmless from any liability for good faith disbursement of earnest money in
     accordance

256  with this Offer or applicable Department of Regulation and Licensing
     regulations concerning earnest money. See Wis. Adm. Code Ch. RL 18. NOTE:

257  WISCONSIN LICENSE LAW PROHIBITS A BROKER FROM GIVING ADVICE OR OPINIONS
     CON-CERNING THE LEGAL RIGHTS OR OBLIGATIONS

258  OF PARTIES TO A TRANSACTION OR THE LEGAL EFFECT OF A SPECIFIC CONTRACT OR
     CONVEYANCE. AN ATTORNEY SHOULD BE CONSULTED

259  IF LEGAL ADVICE IS REQUIRED.
