Upon the demand of any party, any Dispute shall be resolved by binding arbitration (except as set forth in (e) below) in accordance with the terms of this letter. A "Dispute" shall mean any action, dispute, claim or controversy of any kind, whether in contract or tort, statutory or common law, legal or equitable, now existing or hereafter arising under or in connection with, or in any way pertaining to, any of the Loan Documents, or any past, present or future extensions of credit and other activities, transactions or obligations of any kind related directly or indirectly to any of the Loan Documents, including without limitation, any of the foregoing arising in connection with the exercise of any self-help, ancillary or other remedies pursuant to any of the Loan Documents. Any party may by summary proceedings bring an action in court to compel arbitration of a Dispute. Any party who fails or refuses to submit to arbitration following a lawful demand by any other party shall bear all costs and expenses incurred by such other party in compelling arbitration of any Dispute. (b) Governing Rules. Arbitration proceedings shall be administered by the American Arbitration Association ("AAA") or such other administrator as the parties shall mutually agree upon in accordance with the AAA Commercial Arbitration Rules. All Disputes submitted to arbitration shall be resolved in accordance with the Federal Arbitration Act (Title 9 of the United States Code), notwithstanding any conflicting choice of law provision in any of the Loan Documents. The arbitration shall be conducted at a location in Oregon selected by the AAA or other administrator. If there is any inconsistency between the terms hereof and any Barrett Business Services, Inc. May 31, 1998 Page 15 such rules, the terms and procedures set forth herein shall control. All statutes of limitation applicable to any Dispute shall apply to any arbitration proceeding. All discovery activities shall be expressly limited to matters directly relevant to the Dispute being arbitrated. Judgment upon any award rendered in an arbitration may be entered in any court having jurisdiction; provided however, that nothing contained herein shall be deemed to be a waiver by any party that is a bank of the protections afforded to it under 12 U.S.C. ss.91 or any similar applicable state law. (c) No Waiver; Provisional Remedies, Self-Help and Foreclosure. No provision hereof shall limit the right of any party to exercise self-help remedies such as setoff, foreclosure against or sale of any real or personal property collateral or security, or to obtain provisional or ancillary remedies, including without limitation injunctive relief, sequestration, attachment, garnishment or the appointment of a receiver, from a court of competent jurisdiction before, after or during the pendency of any arbitration or other proceeding. The exercise of any such remedy shall not waive the right of any party to compel arbitration hereunder. (d) Arbitrator Qualifications and Powers; Awards. Arbitrators must be active members of the Oregon State Bar or retired judges of the state or federal judiciary of Oregon, with expertise in the substantive law applicable to the subject matter of the Dispute. Arbitrators are empowered to resolve Disputes by summary rulings in response to motions filed prior to the final arbitration hearing. Arbitrators (i) shall resolve all Disputes in accordance with the substantive law of the state of Oregon, (ii) may grant any remedy or relief that a court of the state of Oregon could order or grant within the scope hereof and such ancillary relief as is necessary to make effective any award, and (iii) shall have the power to award recovery of all costs and fees, to impose sanctions and to take such other actions as they deem necessary to the same extent a judge could pursuant to the Federal Rules of Civil Procedure, the Oregon Rules of Civil Procedure or other applicable law. Any Dispute in which the amount in controversy is $5,000,000 or less shall be decided by a single arbitrator who shall not render an award of greater than $5,000,000 (including damages, costs, fees and expenses). By submission to a single arbitrator, each party expressly waives any right or claim to recover more than $5,000,000. Any Dispute in which the amount in controversy exceeds $5,000,000 shall be decided by majority vote of a panel of three arbitrators; provided however, that all three arbitrators must actively participate in all hearings and deliberations. Barrett Business Services, Inc. May 31, 1998 Page 16 (e) Judicial Review. Notwithstanding anything herein to the contrary, in any arbitration in which the amount in controversy exceeds $25,000,000, the arbitrators shall be required to make specific, written findings of fact and conclusions of law. In such arbitrations (i) the arbitrators shall not have the power to make any award which is not supported by substantial evidence or which is based on legal error, (ii) an award shall not be binding upon the parties unless the findings of fact are supported by substantial evidence and the conclusions of law are not erroneous under the substantive law of the state of Oregon, and (iii) the parties shall have in addition to the grounds referred to in the Federal Arbitration Act for vacating, modifying or correcting an award the right to judicial review of (A) whether the findings of fact rendered by the arbitrators are supported by substantial evidence, and (B) whether the conclusions of law are erroneous under the substantive law of the state of Oregon. Judgment confirming an award in such a proceeding may be entered only if a court determines the award is supported by substantial evidence and not based on legal error under the substantive law of the state of Oregon. (f) Miscellaneous. To the maximum extent practicable, the AAA, the arbitrators and the parties shall take all action required to conclude any arbitration proceeding within 180 days of the filing of the Dispute with the AAA. No arbitrator or other party to an arbitration proceeding may disclose the existence, content or results thereof, except for disclosures of information by a party required in the ordinary course of its business, by applicable law or regulation, or to the extent necessary to exercise any judicial review rights set forth herein. If more than one agreement for arbitration by or between the parties potentially applies to a Dispute, the arbitration provision most directly related to the Loan Documents or the subject matter of the Dispute shall control. This arbitration provision shall survive termination, amendment or expiration of any of the Loan Documents or any relationship between the parties. UNDER OREGON LAW, MOST AGREEMENTS, PROMISES AND COMMITMENTS MADE BY BANK AFTER OCTOBER 3, 1989 CONCERNING LOANS AND OTHER CREDIT EXTENSIONS WHICH ARE NOT FOR PERSONAL, FAMILY OR HOUSEHOLD PURPOSES OR SECURED SOLELY BY THE BORROWER'S RESIDENCE MUST BE IN WRITING, EXPRESS CONSIDERATION AND BE SIGNED BY BANK TO BE ENFORCEABLE.
