Yachmetz Title: Senior Vice President - Corporate Strategy & General Counsel 20 APPENDIX A DISPUTE RESOLUTION MECHANISM The parties recognise that a bona fide dispute as to certain matters may arise from time to time during the term of this Agreement that relates to either party's rights and/or obligations. To have such a dispute resolved by this Alternative Dispute ("ADR") provision, a party first must send written notice of the dispute to the other party for attempted resolution by good faith negotiations between the parties. In the event that the parties fail to reach a negotiated resolution within fourteen (14) days after written notice of the dispute, the matter shall be referred to their respective Chief Executive Officers. If the matter has not been resolved by the parties' respective Chief Executive Officers within fourteen (14) days after referral to such Chief Executive Officers, either party may initiate an ADR proceeding as provided herein. The parties shall have the right to be represented by counsel in such a proceeding. 1. To begin an ADR proceeding, a party shall provide written notice to the other party of the issues to be resolved by ADR. Within fourteen (14) days after its receipt of such notice, the other party may, by written notice to the party initiating the ADR, add additional issues to be resolved within the same ADR. 2. Within twenty-one (21) days following receipt of the original ADR notice, the parties shall select a mutually acceptable neutral to preside in the resolution of any disputes in this ADR proceeding. If the parties are unable to agree on a mutually acceptable neutral within such period, either party may request the President of the CPR Institute for Dispute Resolution ("CPR"), 366 Madison Avenue, 14th Floor, New York, NY 10017, to select a neutral pursuant to the following procedures: (a) The CPR shall submit to the parties a list of not less than five (5) candidates within fourteen (14) days after receipt of the request, along with a Curriculum Vitae for each candidate. No candidate shall be an employee, director, or shareholder of either party or any of their subsidiaries or Affiliates. (b) Such list shall include a statement of disclosure by each candidate of any circumstances likely to affect his or her impartiality. (c) Each party shall number the candidates in order of preference (with the number one (1) signifying the greatest preference) and shall deliver the list to the CPR within seven (7) days following receipt of the list of candidates. If a party believes a conflict of interest exists regarding any of the candidates, that party shall provide a written explanation of the conflict to the CPR along with its list showing its order of preference for the candidates. Any party failing to return a list of preferences on time shall be deemed to have no order of preference. 21 (d) If the parties collectively have identified fewer than three (3) candidates deemed to have conflicts, the CPR immediately shall designate as the neutral the candidate for whom the parties collective have indicated the greatest preference. If a tie should result between two (2) candidates, the CPR may designate either candidate. If the parties collectively have identified three (3) or more candidates deemed to have conflicts, the CPR shall review the explanations regarding conflicts and, in its sole discretion, may either (i) immediately designate as the neutral the candidate for whom the parties collectively have indicated the greatest preference, or (ii) issue a new list of not less than five (5) candidates, in which case the procedures set forth in subparagraphs 2(a) - 2(d) shall be repeated. 3. No earlier than twenty-eight (28) days or later than fifty-six (56) days after selection, the neutral shall hold a hearing to resolve each of the issues identified by the parties. The ADR proceeding shall take place at a location agreed upon by the parties. If the parties cannot agree, the neutral shall designate a location other than the principal place of business of either party or any of their subsidiaries or Affiliates. 4. Each party to the proceeding shall be entitled to make one (1) document request to the other party, limited to no more than five (5) specific requests, subject to the right of the neutral to rule on any objection to such request, which shall not be subject to appeal. Any such document request shall be delivered no later than twenty-four (24) days prior to the hearing. Documents in response to such requests shall be provided within ten (10) days of the request. Each party may also take up to three (3) depositions, subject to the right of the neutral to rule on any objection to such deposition, which shall not be subject to appeal. 5. At least seven (7) days prior to the hearing, each party shall submit the following to the other party and the neutral: (a) a copy of all exhibits on which such party intends to rely in any oral or written presentation to the neutral; (b) a list of any witnesses such party intends to call at the hearing, and a short summary of the anticipated testimony of each witness; (c) a pre-hearing brief setting forth the party's factual and legal contentions, as well as its contentions on damages claimed. The brief shall not exceed twenty (20) pages. This page limitation shall apply regardless of the number of issues raised in the ADR proceeding. 6. The hearing shall be conducted on two (2) consecutive days and shall be governed by the following rules: (a) Each party shall be entitled to five (5) hours of hearing time to present its case. The neutral shall determine whether each party has had the five (5) hours to which it is entitled. 22 (b) Each party shall be entitled, but not required, to make an opening statement, to present regular and rebuttal testimony, documents or other evidence, to cross-examine witnesses, and to make a closing argument. Cross-examination of witnesses shall occur immediately after their direct testimony, and cross-examination time shall be charged against the party conducting the cross-examination. (c) The party initiating the ADR shall begin the hearing and, if it chooses to make an opening statement, shall address not only issues it raised but also any issues raised by the responding party. The responding party, if it chooses to make an opening statement, also shall address all issues raised in the ADR. Thereafter, the presentation of regular and rebuttal testimony and documents, other evidence, and closing arguments shall proceed in the same sequence. (d) Except when testifying, witnesses shall be excluded from the hearing until closing arguments. (e) Settlement negotiations, including any statements made therein, shall not be admissible under any circumstances. Affidavits prepared for purposes of the ADR hearing also shall not be admissible. As to all other matters, the neutral shall have sole discretion regarding the admissibility of any evidence. 7. Within seven (7) days following completion of the hearing, each party may submit to the other party and the neutral a post-hearing brief in support of its contentions, provided that such brief shall not contain or discuss any new evidence and shall not exceed ten (10) pages. This page limitation shall apply regardless of the number of issues raised in the ADR proceeding. 8. The neutral shall rule on each disputed issue within fourteen (14) days following completion of the hearing. Such ruling shall adopt in its entirety the proposed ruling and remedy of one of the parties on each disputed issue but may adopt one party's proposed rulings and remedies on some issues and the other party's proposed rulings and remedies on the other issues. The neutral shall not issue any written opinion or otherwise explain the basis of the ruling. 9. The neutral shall be paid a reasonable fee plus expenses. These fees and expenses, along with the reasonable legal fees and expenses of the prevailing party (including all expert witness fees and expenses), the fees and expenses of a court reporter, and any expenses for a hearing room, shall be paid as follows: (a) If the neutral rules in favour of the one party on all disputed issues in the ADR, the losing party shall pay one hundred percent (100%) of such fees and expenses. (b) If the neutral rules in favour of one party on some issues and the other party on other issues, the neutral shall issue with the rulings a written determination as to how such fees and expenses shall be allocated between the parties. The neutral shall allocate fees and expenses in a way that bears a reasonable relationship to the outcome of the ADR, with the party prevailing on more issues, or on issues of greater value or gravity, recovering a relatively larger share of its legal fees and expenses. 23 10. The rulings of the neutral, including rulings on the allocation of fees and expenses, shall be binding, non-reviewable, and non-appealable, and may be entered as a final judgement in any court having jurisdiction. 11. Except as provided in paragraph 10 or as required by law, the existence of the dispute, any settlement negotiations, the ADR hearing, any submissions (including exhibits, testimony, proposed rulings and briefs), and the rulings shall be deemed Confidential Information. The neutral shall have the authority to impose sanctions for unauthorised disclosures of Confidential Information. 25
