9 Article 9. Indemnification 9.1 General. Each Party (the “Indemnifying Party”) shall indemnify, defend and hold harmless the other Party, its Affiliates, and their Representatives and assigns (the “Indemnified Party”) from and against all claims, suits, causes of action, losses, liabilities, liens, damages, assessments, costs, expenses, demands, complaints or actions including but not limited to reasonable attorneys’ fees and court costs (collectively, “Claims”) of third parties concerning: (i) death, personal injury, or property damage of third parties, (ii) nonpayment of wages, benefits, fees, amounts owed, and/or any taxes (including penalties and interest) associated therewith arising from the Indemnifying Party’s Representatives, suppliers, contractors, and/or materialmen and (iii) violations by the Indemnifying Party or any Person for whom the Indemnifying Party is responsible of Applicable Law; in each case to the extent arising or resulting from the Indemnifying Party’s or its Representative’s negligence, willful misconduct, or breach of this Agreement. For sake of clarity, if both Parties are negligent or otherwise at fault or strictly liable without fault, then the obligations of indemnification under this Section 9.1 shall continue, but the Indemnifying Party shall indemnify the Indemnified Party only for the percentage of responsibility for the damage or injuries attributable to the Indemnifying Party. 9.2 Indemnification Procedures. 9.2.1 If an Indemnified Party receives written notice of a Claim, the Indemnified Party shall give prompt written notice to the Indemnifying Party, including a reasonably detailed description of the facts and circumstances relating to such Claim, a complete copy of all notices, pleadings and other papers related thereto, and a description in reasonable detail of the basis for the potential claim for indemnification with respect thereto. The Indemnified Party’s delay or deficiency in notifying the Indemnifying Party shall not relieve the Indemnifying Party of liability or obligation except to the extent (and only to the extent) such delay materially impacts the defense of the Claim. 9.2.2 The Indemnifying Party shall be entitled to assume the defense and to represent the interests of the Indemnified Party, which shall include the right to select and direct legal counsel and other consultants (all of whom shall be reasonably acceptable to the Indemnified Party), appear in proceedings on behalf of the Indemnified Party and to propose, accept or reject offers of settlement, subject to Section 9.2.3 below, all at its sole cost. Nothing herein shall prevent an Indemnified Party from retaining its own legal counsel and other consultants or participating in its own defense at its own cost and expense. Notwithstanding the foregoing, if (i) the claim is primarily for non-monetary damages against the Indemnified Party, or primarily for an injunction or other equitable relief that, if granted, would reasonably be expected to be material to the Indemnified Party, (ii) there is a material actual or potential conflict of interest that makes representation of the Indemnifying Party and the Indemnified Party by the same counsel or the counsel selected by the Indemnifying Party inappropriate, or (iii) the claim is a criminal proceeding, then in each case the Indemnified Party may, upon notice to the Indemnifying Party, assume the exclusive right to defend (and in the case of clause (iii) above, compromise and settle), such claim and the reasonable fees and expenses of the Indemnified Party’s separate counsel shall be borne by the Indemnifying Party; however the settlement of any claim pursuant to clauses (i) and (ii) above shall be governed by Section 9.2.3 below. Notwithstanding anything to the contrary herein, for sake of clarity, the Parties agree that the foregoing provisions shall not be construed so as to permit the Indemnified Party to control or assume the defense of any action, lawsuit, proceeding, investigation, demand or other claim brought against the Indemnifying Party concurrently with or in a joint proceeding in respect of any claim that is the subject of an indemnification claim hereunder by the Indemnified Party.

10 9.2.3 Notwithstanding anything to the contrary herein, the Indemnifying Party shall not compromise or settle, or admit any liability with respect to any third party Claim without the prior written consent of the Indemnified Party (which consent shall not be unreasonably withheld or delayed), unless the relief consists solely of (i) money damages (all of which the Indemnifying Party shall pay), and (ii) includes a provision whereby the plaintiff or claimant in the matter releases the Indemnified Party from all liability with respect thereto. If the Indemnified Party assume the defense of or represents their own interests, no settlement shall be made without the prior written consent of the Indemnifying Party (which consent shall not be unreasonably withheld or delayed). 9.3 Limited Waiver of Certain Immunities. Each of the Parties hereby specifically and expressly agrees that with respect to any and all claims against an Indemnified Party by any representative of an Indemnifying Party, any indemnification available hereunder shall not be limited by reason of any immunity to which such Indemnifying Party may be entitled under any workers compensation and/or industrial insurance acts, disability benefit acts, or other employee benefits acts and any limitation on the amount or type of damages, compensation, or benefits payable by or for the Indemnifying Party to such representative with respect to any such claim. For the sake of clarity, the Indemnifying Party’s waiver of immunity by the provisions of this section extends only to indemnification claims against the Indemnifying Party by or on behalf of the Indemnified Party under or pursuant to this agreement, and does not apply to any claims made by the Indemnifying Party’s representatives directly against the Indemnifying Party. 9.4 Survival. The indemnities set forth in this Article 9 shall survive the termination or expiration of this Agreement. Article 10. Term and Termination 10.1 Term. The term of this Agreement shall commence as of the Effective Date and shall continue until the fourth (4th) anniversary thereof (the “Initial Term”) and thereafter shall be automatically extended in successive one (1) year increments (the Initial Term together with any such extensions, the “Term”). 10.2 Early Termination. Either Party may terminate this Agreement effective upon the expiration of the Initial Term or the expiration of any extension thereof upon not less than six (6) months prior written notice of termination furnished to the other Party. No termination of this Agreement pursuant to this Section 10.2 shall affect any Purchase Orders executed between the Parties prior to the date of termination or any Consortium Agreement then in effect. 10.3 Transition. If this Agreement is terminated pursuant to this Section 10.2, the Parties shall cooperate to manage any projects or opportunities in progress so as to ensure minimal disruption to the end customer, subject to compliance with Applicable Law (including antitrust requirements). Each Party shall submit a list of opportunities in progress for which the Parties agree to continue working together and where existing sales arrangements will be honored through completion. 10.4 Termination for Cause and other Remedies. A Party may terminate this Agreement for cause and/or pursue such other rights and remedies as may be available to it at law or in equity, upon thirty (30) days prior written notice in the event the other Party hereto materially breaches this Agreement and fails to cure the breach within thirty (30) days after receipt of written demand therefor.

The arbitrators shall allocate the fees and costs of the arbitration. The losing Party(ies) shall pay the prevailing Party(ies)’ attorney’s fees and costs and the costs associated with the arbitration, including the expert fees and costs and the arbitrators’ fees and costs borne by the prevailing Party(ies), all as determined by the arbitrators.

Without prejudice to such

14 provisional remedies as may be available under the jurisdiction of a national court, the arbitral tribunal shall have full authority to grant provisional remedies or order the Parties to request that a court modify or vacate any temporary or preliminary relief issued by a court, and to award damages for the failure of any Party to respect the arbitral tribunal’s orders to that effect.
