"REFERENCE PROVISION 1. Other than (i) non-judicial foreclosure and all matters in connection therewith regarding security interests in real or personal property; or (ii) the appointment of a receiver, or the exercise of other provisional remedies (any and all of which may be initiated pursuant to applicable law), each controversy, dispute or claim between the parties arising out of or relating to this Note ("Agreement"), which controversy, dispute or claim is not settled in writing within thirty (30) days after the "Claim Date" (defined as the date on which a party subject to the Agreement gives written notice to all other parties that a controversy, dispute or claim exists), will be settled by a reference proceeding in California in accordance with the provisions of Section 638 ET SEQ. of the California Code of Civil Procedure, or their successor section ("CCP"), which shall constitute the exclusive remedy for the settlement of any controversy, dispute or claim concerning this Agreement, including whether such controversy, dispute or claim is subject to the reference proceeding and except as set forth above, the parties waive their rights to initiate any legal proceedings against each other in any court or jurisdiction other than the Superior Court in the County where the real property securing this Agreement, if any, is located or Los Angeles County if none (the "Court"). The referee shall be a retired Judge of the Court selected by mutual agreement of the parties, and if they cannot so agree within forty-five (45) days after the Claim Date, the referee shall be promptly selected by the presiding Judge of the Court (or his representative). The referee shall be appointed to sit as a temporary judge, with all of the powers of a temporary judge, as authorized by law, and upon selection should take and subscribe to the oath of office as provided for in Rule 244 of the California Rules of Court (or any subsequently enacted Rule). Each party shall have one peremptory challenge pursuant to CCP Section 170.6. The referee shall (a) be requested to set the matter for hearing within sixty (60) days after the Claim Date and (b) try any and all issues of law or fact and report a statement of decision upon them, if possible, within ninety (90) days of the Claim Date. Any decision rendered by the referee will be final, binding and conclusive and judgment shall be entered pursuant to CCP Section 644 in any court in the State of California having jurisdiction. Any party may apply for a reference proceeding at any time after thirty (30) days following notice to any other party of the nature of the controversy, dispute or claim, by filing a petition for a hearing and/or trial. All discovery permitted by this Agreement shall be completed no later than fifteen (15) days before the first hearing date established by the referee. The referee may extend such period in the event of a party's refusal to provide requested discovery for any reason whatsoever, including, without limitation, legal objections raised to such discovery or unavailability of a witness due to absence or illness. No party shall be entitled to "priority" in conducting discovery. Depositions may be taken by either party upon seven (7) days written notice, and request for production or inspection of documents shall be responded to within Ten (10) days after service. All disputes relating to discovery which cannot be resolved by the parties shall be submitted to the referee whose decision shall be final and binding upon the parties. Pending appointment of the referee as provided herein, the Superior Court is empowered to issue temporary and/or provisional remedies, as appropriate. 2. Except as expressly set forth in this Agreement, the referee shall determine the manner in which the reference proceeding is conducted including the time and place of all hearings, the order of presentation of evidence, and all other questions that arise with respect to the course of the reference proceeding. All proceedings and hearings conducted before the referee, except for trial, shall be conducted without a court reporter, except that when any party so requests, a court reporter will be used at any hearing conducted before the referee. The party making such a request shall have the obligation to arrange for and pay for the court reporter. The costs of the court reporter at the trial shall be borne equally by the parties. 3. The referee shall be required to determine all issues in accordance with existing case law and the statutory laws of the State of California. The rules of evidence applicable to proceedings at law in the State of California will be applicable to the reference proceeding. The referee shall be empowered to enter equitable as well as legal relief, to provide all temporary and/or provisional remedies and to enter equitable orders that will be binding upon the parties. The referee shall issue a single judgment at the close of the reference proceeding which shall dispose of all of the claims of the parties that are the subject of the reference. The parties hereto expressly reserve the right to contest or appeal from the final judgment or any appealable order or appealable judgment entered by the referee. The parties hereto expressly reserve the right to findings of fact, conclusions of law, a written statement of decision, and the right to move for a new trial or a different judgment, which new trial, if granted, is also to be a reference proceeding under this provision. 4. In the event that the enabling legislation which provides for appointment of a referee is repealed (and no successor statute is enacted), any dispute between the parties that would otherwise be determined by the reference procedure herein described will be resolved and determined by arbitration. The arbitration will be conducted by a retired judge of the Court, in accordance with the California Arbitration Act, Section 1280 through Section 1294,2 of the CCP amended from time to time. The limitations with respect to discovery as set forth hereinabove shall apply to any such arbitration proceeding." Initial Here ML ------ Initial Here WD ------
