The provisions of this arbitration clause shall survive any termination, amendment, or expiration of the Note or Related Agreements. The provisions of this arbitration clause shall supersede any prior arbitration agreement between or among the parties.

(b) The arbitration proceedings shall be conducted in a city mutually agreed by the parties. Absent such an agreement, arbitration will be conducted in Phoenix, Arizona or such other place as may be determined by the Administrator. The Administrator and the arbitrator(s) shall have the authority to the extent practicable to take any action to require the arbitration proceeding to be completed and the arbitrator(s)' award issued within 150 days of the filing of the Dispute with the Administrator. The arbitrator(s) shall have the authority to impose sanctions on any party that tails to comply with time periods imposed by the Administrator or the arbitrator(s), including the sanction of summarily dismissing any Dispute or defense with prejudice. The arbitrator(s) shall have the authority to resolve any Dispute regarding the terms of this agreement, this arbitration clause, or Related Agreements, including any claim or controversy regarding the arbitrability of any Dispute. All limitations periods applicable to any Dispute or defense, whether by statute or agreement, shall apply to any arbitration proceeding hereunder and the arbitrator(s) shall have the authority to decide whether any Dispute or defense is barred by a limitations period and, if so, to summarily enter an award dismissing any Dispute or defense on that basis. The doctrines of compulsory counterclaim, res judicata, and collateral estoppel shall apply to any arbitration proceeding hereunder so that a party must state as a counterclaim in the arbitration proceeding any claim or controversy which arises out of the transaction or occurrence that is the subject matter of the Dispute. The arbitrator(s) may in the arbitrator(s)' discretion and at the request of any party: (1) consolidate in a single arbitration proceeding any other claim arising out of the same transaction involving another party to that transaction that is bound by an arbitration clause with Lender, such as borrowers, guarantors. sureties, and owners of collateral; and

(2) consolidate or administer multiple arbitration claims or controversies as a class action in accordance with Rule 23 of the Federal Rules of Civil Procedure.

(c) The arbitrator(s) shall be selected in accordance with the rules of the Administrator from panels maintained by the Administrator. A single arbitrator shall have expertise in the subject matter of the Dispute. Where three arbitrators conduct an arbitration proceeding, the Dispute shall be decided by a majority vote of the three arbitrators, at least one of whom must have expertise in the subject matter of the Dispute and at least one of whom must be a practicing attorney. The arbitrator(s) shall award to the prevailing party recovery of all costs and fees (including attorneys' fees and costs, arbitration administration fees and costs, and arbitrator(s)' fees). The arbitrator(s), either during the pendency of the arbitration proceeding or as part of the arbitration award, also may grant provisional or ancillary remedies, including, but not limited to, an award of injunctive relief, foreclosure, sequestration, attachment, replevin, garnishment, or the appointment of a receiver.

(d) Judgment upon an arbitration award may be entered in any court having jurisdiction, subject to the following limitation: the arbitration award is binding upon the parties only if the amount does not exceed Four Million Dollars ($4,000,000.00); if the award exceeds that limit, either party may demand the right to a court trial. Such a demand must be filed with the Administrator within thirty (30) days following the date of the arbitration award; if such a demand is not made with that time period, the amount of the arbitration award shall be binding. The computation of the total amount of an arbitration award shall include amounts awarded for attorneys' fees and costs, arbitration administration fees and costs, and arbitrator(s)' fees.

Such rights can be exercised at any time, before or after initiation of an arbitration proceeding, except to the extent such action is contrary to the arbitration award. The exercise of such rights shall not constitute a waiver of the right to submit any Dispute to arbitration, and any claim or controversy related to the exercise of such rights shall be a Dispute to be resolved under the provisions of this arbitration clause. Any party may initiate arbitration with the Administrator, If any party desires to arbitrate a Dispute asserted against such party in a complaint, counterclaim, cross-claim, or third-party complaint thereto, or in an answer or other reply to any such pleading, such party must make an appropriate motion to the trial court seeking to compel arbitration, which motion must be filed with the court within 45 days of service of the pleading, or amendment thereto, setting forth such Dispute, If arbitration is compelled after commencement of litigation of a Dispute, the party obtaining an order compelling arbitration shall commence arbitration and pay the Administrator's filing fees and costs within 45 days of entry of such order. Failure to do so shall constitute an agreement to proceed with litigation and waiver of the right to arbitrate. In any arbitration commenced by a consumer regarding a consumer Dispute, Lender shall pay one-half of the Administrator's filing fee, up to $250.

(f) Notwithstanding the applicability of any other law to the Note, the arbitration clause, or Related Agreements between or among the parties, the Federal Arbitration Act, 9 U.S.C. Section 1, et seq., shall apply to the construction and interpretation of this arbitration clause. If any provision of this arbitration clause should be determined to be unenforceable, all other provisions of this arbitration clause shall remain in full force and effect.
