11.2 By SDSP. SDSP may terminate this Agreement prior to Closing by giving written notice of termination to Sellers if: (i) Sellers have made a material misrepresentation or are in material breach of the representations and warranties contained in this Agreement; (ii) Sellers are in material default in observance of or in the due and timely performance of any of the agreements and covenants contained in the Agreement; or (iii) Sellers are in material breach of a condition of Closing that has not been previously waived by SDSP.

11.4 Disclosure of Breach. A breach may not be declared if the action or inaction of a party is capable of cure and the party intending to declare the breach has not given the other party at least 30 days’ prior written notice within which such impending breach may be cured.

12. DISPUTE RESOLUTION

12.1 Mediation. The parties hope there will be no disputes arising out of this transaction. To that end, each commits to cooperate in good faith and to deal fairly in performing its duties under this Agreement in order to accomplish their mutual objectives and avoid disputes. But if a dispute arises, the parties agree to resolve all disputes by the following alternate dispute resolution process. The parties will seek a fair and prompt negotiated resolution, but if this is not successful, all disputes shall be resolved by binding arbitration; provided, however, that during this process, at the request of either party made not later than twenty-five (25) days after the initial arbitration demand, the parties will attempt to resolve any dispute by nonbinding mediation (but without delaying the arbitration hearing date). The parties recognize that negotiation or mediation may not be appropriate to resolve some disputes and agree that either party may proceed with

arbitration without negotiating or mediating. The parties confirm that by agreeing to this alternate dispute resolution process, they intend to give up their right to have any dispute decided in court by a judge or jury, except to the extent that there is a right to appeal provided under Section 12.4.

12.2 Binding Arbitration. Any claim between the parties, including but not limited to those arising out of or relating to this Agreement and any claim based on or arising from an alleged tort, shall be determined by arbitration in Des Moines, Iowa (or some other place as the parties may agree). If a party demands a total award greater than $250,000, including interest, attorneys’ fees, and costs, then any party may require that there be three (3) neutral arbitrators. If the parties cannot agree on the identity of the arbitrator(s) within ten (10) days of the arbitration demand, the arbitrator(s) shall be selected by the administrator of the American Arbitration Association (AAA) office having jurisdiction over Des Moines, Iowa, from its Large, Complex Case Panel (or have similar professional credentials). Each arbitrator shall be an attorney with at least fifteen (15) years’ experience in commercial law and shall reside in Iowa. Whether a claim is covered by this Agreement shall be determined by the arbitrator(s). All statutes of limitations which would otherwise be applicable shall apply to any arbitration proceeding hereunder.

12.3 Procedures. The arbitration shall be conducted in accordance with the AAA Commercial Arbitration Rules with Expedited Procedures, as modified by this Agreement. There shall be no dispositive motion practice. As may be shown to be necessary to ensure a fair hearing, the arbitrator(s) may authorize limited discovery, and may enter pre-hearing orders regarding (without limitation) scheduling, document exchange, witness disclosure and issues to be heard. The arbitrator(s) shall not be bound by the rules of evidence or of civil procedure, but may consider such writings and oral presentations as reasonable business people would use in the conduct of their day-to-day affairs, and may require the parties to submit some or all of their case by written declaration or such other manner of presentation as the arbitrator(s) may determine to be appropriate. The parties intend to limit live testimony and cross-examination to the extent necessary to ensure a fair hearing on material issues.

12.4 Hearing and Award. The arbitrator(s) shall take such steps as may be necessary to hold a private hearing within 90 days of the initial demand for arbitration and to conclude the hearing within three days; and the arbitrator(s)’s written decision shall be made not later than 14 calendar days after the hearing. The parties have included these time limits in order to expedite the proceeding, but they are not jurisdictional, and the

arbitrator(s) may, for good cause afford or permit reasonable extensions or delays, which shall not affect the validity of the award. The written decision shall contain a brief statement of the claim(s) determined and the award made on each claim. In making the decision and award, the arbitrator(s) shall apply applicable substantive law. Absent fraud, collusion or willful misconduct by an arbitrator, the award shall be final, and judgment may be entered in any court having jurisdiction thereof. The arbitrator(s) may award injunctive relief or any other remedy available from a judge, including the joinder of parties or consolidation of this arbitration with any other involving common issues of law or fact or which may promote judicial economy, and may award attorneys’ fees and costs to the prevailing party but shall not have the power to award punitive or exemplary damages. The decision and award of the arbitrators need not be unanimous; rather, the decision and award of two arbitrators shall be final.
