9.4 Procedure for Indemnified Third Party Claim

(a) Promptly after receipt by a Party entitled to indemnification hereunder (the “Indemnitee”) of written notice of the assertion or the commencement of any Litigation with respect to any matter referred to in Section 9.1 or 9.2, as applicable, the Indemnitee shall give written notice thereof to the Party required to make indemnification hereunder (the “Indemnitor”), and thereafter shall keep the Indemnitor reasonably informed with respect thereto; provided, however, that failure of the Indemnitee to give the Indemnitor notice as provided herein shall not relieve the Indemnitor of its obligations hereunder except to the extent that the Indemnitor is prejudiced thereby. If any third party commences any Litigation against an Indemnitee, the Indemnitor shall be entitled to participate in such Litigation and, at its option, assume the defense thereof with counsel reasonably satisfactory to the Indemnitee, at the Indemnitor’s sole expense; provided, however, that the Indemnitor shall not have the right to assume the defense of any Litigation if:

(i) the Indemnitee shall have one or more legal or equitable defenses available to it which are different from or in addition to those available to the Indemnitor, and, in the reasonable opinion of the Indemnitee, counsel for the Indemnitor could not

- 34 -

adequately represent the interests of the Indemnitee because such interests could be in conflict with those of the Indemnitor;

(ii) such Litigation is reasonably likely to have a material adverse effect on any other matter beyond the scope or limits of the indemnification obligation of the Indemnitor; or

(iii) the Indemnitor shall not have assumed the defense of the Litigation in a timely fashion (but in any event within thirty (30) days of notice of such Litigation).

(b) If the Indemnitor shall assume the defense of any Litigation, the Indemnitee shall be entitled to participate in any Litigation at its expense, and the Indemnitor shall not settle such Litigation unless the settlement shall include as an unconditional term thereof the giving by the claimant or the plaintiff of a full and unconditional release of the Indemnitee, from all liability with respect to the matters that are subject to such Litigation, or otherwise shall have been approved reasonably by the Indemnitee. The Indemnitee shall co-operate with the Indemnitor so as to permit the Indemnitor to conduct such negotiation, settlement and defence and for this purpose shall preserve all relevant documents in relation to the Litigation, allow the Indemnitor access on reasonable notice to inspect and take copies of all such documents and require its personnel to provide such statements as the Indemnitor may reasonably require and to attend and give evidence at any trial or hearing in respect of the Litigation.

(c) If the Indemnitor does not have the right to assume the defense of any Litigation in accordance with Section 9.4(a), then the Indemnitor shall be entitled to participate in any such Litigation at its expense, and the Indemnitee shall not settle any such Litigation without the prior written consent of the Indemnitor..

9.5 Thresholds and Determination of Indemnification Amounts

(a) No Losses may be recovered from the Purchaser pursuant to Section 9.1(a) unless and until the accumulated aggregate amount of Losses of BaseCore and any other Indemnitees arising pursuant to Section 9.1(a) exceeds [Redacted – commercially sensitive information], in which event the accumulated aggregate amount of all such Losses may be recovered, up to a maximum of [Redacted – commercially sensitive information] of the Purchase Price. Such limitation shall have no application to any claim to recover Losses based on any incorrectness in or breach of any representation or warranty of the Purchaser in this Agreement or in any other agreement, certificate or instrument executed and delivered pursuant to this Agreement resulting from intentional misrepresentation, wilful breach or fraud by BaseCore.

(b) For purpose of this Article 9, (i) any dollar amount referred to in Section 9.5(a) that is expressed in Canadian dollars shall be converted into U.S. dollars based on the Exchange Rate, and (ii) any Losses that are subject to indemnification and that are expressed in Canadian dollars shall be paid in U.S. dollars based on the Exchange Rate.

9.6 Sole Remedy

10.2 Disputes and Arbitration

(b) Subject to such matters to be resolved in accordance with Section 10.2(c), a Party may refer a Dispute which has not been resolved by the chief executive officers in accordance with Section 10.2(a) to binding arbitration in accordance with the Arbitration Rules of the ADR Institute of Canada, Inc. (the “Arbitration Rules”) but, subject to the agreement of both Parties, the ADR Institute of Canada, Inc. (the “ADRIC”) is not required to administer the arbitration (the “Arbitration”). Unless otherwise agreed to in writing by the Parties:

(i) if an Arbitration is in respect of a claim for damages for less than or equal to [Redacted – commercially sensitive information], it shall be conducted before one arbitrator. Otherwise, the Arbitration shall be heard and determined by three arbitrators. The arbitrator or arbitrators, as the case may be, shall be retired judges or senior legal practitioners with significant experience in commercial disputes and shall be appointed in the following manner:

(A) if the Arbitration shall be conducted before a panel of one arbitrator, the Parties shall mutually agree upon the arbitrator. If the Parties are unable to agree upon an arbitrator within ten (10) days of the referral to Arbitration, the arbitrator shall be appointed in accordance with the Arbitration Rules and the Arbitration shall proceed thereafter as an administered arbitration under the auspices of the ADRIC; and

(B) if the Arbitration shall be conducted before a panel of three arbitrators, the Parties shall each appoint one arbitrator within ten (10) days of the referral to Arbitration.

(c) The Parties may not commence legal proceedings in any court in connection with a Dispute with the exception that a Party may, in its sole discretion, apply at any time to a court of competent jurisdiction for urgent interlocutory relief, or to enforce an interim or final decision, order or award from an Arbitration. Each of the Parties irrevocably submits to the non-exclusive jurisdiction of the courts of the Province of Ontario for the purpose of seeking any such relief.

(d) The Parties agree that irreparable damage would occur in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached, and that money damages or legal remedies would not be an adequate remedy for any such damages. Therefore, it is accordingly agreed that, in addition to any other remedy to which they are entitled at law or in equity, each Party shall be entitled to enforce specifically the terms and provisions of this Agreement, or to enforce compliance with, the covenants and obligations of the other Party, and appropriate injunctive relief shall be granted in connection therewith. Any Party seeking an injunction, a decree or order of specific performance shall not be required to provide any bond or other security in connection therewith and any such remedy shall be in addition and not in substitution for any other remedy to which such Party is entitled at law or in equity.
