Mandatory Arbitration. Any dispute or controversy arising under or in connection with this Agreement shall be settled exclusively by binding arbitration in the manner set forth in this Section 11(l). Either party may submit any claim arising under or in connection with this Agreement for binding arbitration before an arbitrator in Hennepin County, Minnesota, in accordance with the commercial arbitration rules of the American Arbitration Association, as then in effect, or pursuant to such other form of alternative dispute resolution as the parties may agree (collectively, the “arbitration”). The arbitrator’s sole authority shall be to interpret and apply the provisions of this Agreement; the arbitrator shall not change, add to, or subtract from, any of its provisions. The arbitrator shall have the power to compel attendance of witnesses at the hearing. Any court having competent jurisdiction may enter a judgment based upon such arbitration. The arbitrator shall be appointed by mutual agreement of the Corporation and the claimant pursuant to the applicable commercial arbitration rules. The arbitrator shall be a professional person with a national reputation for expertise in employee benefit matters and who is unrelated to the claimant and any employees of the Corporation. All decisions of the arbitrator shall be final and binding on the claimant and the Corporation.
