Wherever there is any conflict between any provision of this Agreement and any statute, law, regulation or judicial precedent, the latter shall prevail, but in such extent the provisions of this Agreement thus affected shall be curtailed and limited only to the extent necessary to bring it within the requirements of the law. In the event that any part, section, paragraph or clause of this Agreement shall be held by a court of proper jurisdiction to be invalid or unenforceable, the entire Agreement shall not fail on account thereof, but the balance of the Agreement shall continue in full force and effect unless such construction would clearly be contrary to the intention of the parties or would result in unconscionable justice. 9.04 Grievances. The parties to this Agreement hereby agree that any claims or disputes between the parties arising out of or concerning this Agreement shall be presented in writing to all of the parties hereto within ninety (90) days of the discovery of the facts leading to such claim or dispute, and that the party claimed to have been at fault shall respond in writing to such complainant within thirty (30) days of receipt of such notice. The claimant(s) and respondent(s) will exercise all reasonable means to resolve and/or rectify such grievances within 120 days of receipt of the original complaint. 9.05 Arbitration. The parties to this Agreement hereby agree that any claims or disputes between the parties arising out of or concerning this Agreement, which are not rectified under Section 9.05 shall be submitted to binding and mandatory arbitration as follows: 9.05.1 Any controversy or claim arising out of or relating to this Agreement or the breach thereof, shall be settled by arbitration in Albuquerque, New Mexico in accordance with the rules of conciliation and arbitration of the American Arbitration Association then in effect (the "Rules") and judgment upon the award rendered by the arbitrator(s) may be entered in any court having jurisdiction thereof. 9.05.2 Any claim, notice of which is not given in writing to the other parties within ninety (90) days of (i) the date of occurrence or the last date to occur of the facts on which said claim is based, or (ii) the date of discovery of such facts (unless the date by which such facts would have been discovered had the claimant exercised ordinary care and diligence is an earlier date, in which case such earlier date shall be substituted for the date of such discovery) shall be forever barred. 9.05.3 Arbitrator(s) selected in connection with a proceeding hereunder need not be residents of the State of New Mexico. 9.05.4 Each of the parties will cooperate with the others in establishing, prior to the selection of any arbitrator, appropriate qualifications and criteria for selection, and will attempt to agree upon and select a single arbitrator. If the parties fail to agree on such qualifications and criteria or to select a single arbitrator then such selection shall be made in accordance with the Rules provided that, in any dispute which shall require a decision as to the existence, scope or applicability of rights in intellectual property, any arbitrator selected by whatever means shall possess a reasonable degree of expertise and experience in dealing with such disputes. 9.05.5 All reasonable efforts shall be made to hold a hearing on the claims submitted within sixty (60) days after the appointment of the arbitrator(s). In conducting the hearing the arbitrator(s) are hereby directed, where feasible, to adhere to the then-existing American Arbitration Association Procedures and Rules relating to commercial disputes. The parties to each claim shall be equally liable for the reasonable expenses of the arbitrators hearing the dispute, and the arbitrators shall each be compensated for the proceedings. The parties agree to advance in equal amounts the expected amount of required compensation as estimated by the arbitrators at the commencement of the proceedings. As provided below, however, the arbitrators may ultimately assess such compensation against any party as part of their decision. 9.05.6 The decision or award of the arbitrator(s) shall be given in writing within thirty (30) days after the conclusion of the hearing, but failure to give such decision within such period will not invalidate the same. The arbitrator(s) are authorized hereby to award not only damages but also specific performance, if such relief in their opinion is appropriate. The arbitrators shall include in their award reasonable attorney's fees (which the parties hereto agree by contract to be part of the damages due) to the party or parties the arbitrator deem to be the prevailing party, unless the arbitrators expressly find that such an award would be inappropriate under the circumstances of the dispute. The arbitrators may also assess against any party any or all costs and expenses of the arbitration. 9.05.7 The award or decision of the arbitrators shall be final and conclusive in all respects and the parties hereto expressly waive any right of appeal or judicial review of the same. Nothing herein shall prevent any party from petitioning a court specified in section 12.01 above to enforce such decision or award. 9.05.8 Any party hereto shall be entitled to recover reasonable attorney's fees and costs incurred in enforcing any arbitration award or decision made pursuant hereto. In addition, any party who refuses to submit a dispute to arbitration as provided herein, or who brings suit on a claim or dispute that is subject to arbitration as provided herein without first submitting such claim to the grievance process and arbitration set forth, shall pay the reasonable attorney's fees and other expenses incurred by any party hereto required to enforce the arbitration provisions hereof and/or to obtain a stay or dismissal of such legal proceedings. 9.06 Execution of Multiple Counterparts. This Agreement may be executed in multiple counterparts. Each such copy bearing the original authorized signature of the Purchaser and the original authorized signatures of the Seller, LSR, and the Individual Shareholders shall have the full force and effect of a complete original agreement between the signatories and any complete counterset of original signatures shall be considered a complete original Agreement.
