Such suspension order shall designate the amount and type of activities to be suspended. Company may provide verbal notice of the suspension order to Manager in an urgent situation; provided that Company shall deliver a written notice of such suspension to Manager within twenty-four (24) hours thereafter. Upon receipt of any such suspension order, Manager shall, unless the notice requires otherwise:

During any interruption in operations or Company-ordered suspension or other suspension or delay, Manager shall continue to be paid the Fee and reimbursed for Reimbursable Expenses, as applicable, in accordance with Article IV hereof for a period of ninety (90) days following such interruption, suspension or delay, without regard to whether any interruption, suspension or delay is a result of Company’s decision, Force Majeure, strike or other labor disturbance not contemplated under Article VII, temporary shutdown or any and all other cause of such interruption or suspension. After a period of ninety (90) days following such interruption, suspension or delay, either Company or Manager may request an equitable increase or decrease in the Fee by providing written notice of such request to the other party. In the case of any dispute related to the adjustment of the Fee, the objecting party shall deliver to the other party a Dispute Notice with such detail as described in Section 4.4(e) and shall follow the procedures to resolve such dispute in good faith as described above in Sections 4.4(g) and 4.4(h). For the avoidance of doubt, Manager shall not be entitled to be paid an Annual Incentive Fee or any portion thereof with respect to such interruption period.

If Company fails to pay Manager any undisputed amount due under this Agreement within ten (10) Business Days after the expiration of the time within which payment is to be made, Manager may terminate this Agreement, in each instance after giving not less than seven (7) days prior notice to Company. Such action shall not prejudice Manager’s rights to payment under Article IV hereof.

(b) Resumption Upon Cure. If Manager suspends or reduces the Services and Company subsequently pays the entire undisputed amount due (prior to Manager’s termination of the Agreement in accordance with Section 5.5(a) above), Manager’s right to terminate this

Agreement shall lapse in respect of such delayed payments, and Manager shall resume normal working as soon as is reasonably possible.

5.6 Right to Terminate for Extended Suspension. In the event of a suspension ordered by Company lasting more than ninety (90) consecutive days, Manager shall have the right to terminate this Agreement, provided that such termination shall not prejudice Manager’s rights to payment under Section 13.7(i) (but subject to Section 5.4 above) and (ii) hereof.

(a) Company shall indemnify and hold harmless Manager, VPGM, Senior Management and Manager’s officers, directors, and employees (each, a “Manager Indemnified Party”) absent gross negligence, willful misconduct or bad faith, from and against any and all claims, liabilities, damages, losses, costs, and expenses (including, but not limited to, amounts paid in satisfaction of judgments, in compromises and settlements, as fines and penalties and reasonable attorneys’ fees for defending against any claim or alleged claim, except for and excluding any liabilities for taxes and social security contributions of any Manager Indemnified Party), which are incurred by such Manager Indemnified Party and arise out of or in connection with the business of Company or the performance by such Manager Indemnified Party of its responsibilities hereunder.

(b) Manager shall indemnify and hold harmless Company, and its officers, directors, “síndicos”, employees and Affiliates (each, a “Company Indemnified Party”, together with Manager Indemnified Parties, an “Indemnified Party”) from and against any and all claims, liabilities, damages, losses, costs, and expenses (including, but not limited to, amounts paid in satisfaction of judgments, in compromises and settlements, as fines and penalties and reasonable attorneys’ fees for defending against any claim or alleged claim but excluding any liabilities for taxes and social contributions of any Manager Indemnified Party), which are incurred by such Company Indemnified Party as described below.

(i) Manager shall not be liable for any loss, damage, liability, injury, claim or expense attributable to the provision of the Services, whether claimed to result from

breach of contract, warranty, tort, negligence, strict liability, delay, error or omission, indemnity or otherwise, except that Manager shall be liable for losses that arise or is alleged to have arisen from its, Senior Management’s or its employees’ gross negligence, willful misconduct or bad faith in the performance of its obligations or obligations of Senior Management or Manager’s employees under this Agreement.

11.2 Claims of Indemnification. An Indemnified Party shall not be entitled to indemnification hereunder to the extent such claim arises from such Indemnified Party’s gross negligence, willful misconduct or bad faith. The termination of any proceeding by settlement, judgment, order, or upon a plea of nolo contendre or its equivalent shall not, of itself, create a presumption that an Indemnified Party was grossly negligent or engaged in willful misconduct or bad faith. Any person or entity entitled to indemnification from the Indemnifying Party hereunder shall obtain the written consent of the Indemnifying Party (which consent shall not be unreasonably withheld) prior to entering into any agreement or settlement that would result in an obligation of the Indemnifying Party to indemnify such person or entity.

(a) Expenses incurred by an Indemnified Party in defense or settlement of any claim that may be subject to a right of indemnification hereunder may be advanced by the Indemnifying Party prior to the final disposition thereof upon receipt of an undertaking by or on behalf of the Indemnified Party to repay such amount to the extent that it shall be determined ultimately that such Indemnified Party is not entitled to be indemnified hereunder. The right of any Indemnified Party to the indemnification provided herein shall be cumulative of, and in addition to, any and all rights to which such Indemnified Party may otherwise be entitled by contract or as a matter of law or equity and shall be extended to such Indemnified Party’s successors, assigns, and legal representatives.

(b) Promptly after receipt by an Indemnified Party of notice of the commencement of any action or proceeding or threatened action or proceeding in connection with any claim, such Indemnified Party shall give written notice thereof to the Indemnifying Party; provided that the failure of an Indemnified Party to give such notice shall not relieve the Indemnifying Party of its obligations pursuant to this Section 11.1, except to the extent that the Indemnifying Party is actually prejudiced by such failure to give notice.

(c) In case any action or proceeding is commenced against any Indemnified Party which may be subject to indemnification pursuant to this Section 11.2, the Indemnifying Party shall have the right to assume the defense thereof, with counsel reasonably satisfactory to such Indemnified Party. After notice from the Indemnifying Party to such Indemnified Party of the Indemnifying Party’s election to assume the defense thereof, the Indemnifying Party will be liable for the expenses subsequently incurred by such Indemnified Party in connection with the defense thereof. The Indemnifying Party will not consent to the entry of any judgment or enter

into any settlement that does not include as an unconditional term the giving to such Indemnified Party a release from all liability in respect of such claim.

(d) If it is determined pursuant to subsequent judicial appeal that an Indemnified Party was not entitled to claim indemnification under this Article XI, the Indemnified Party shall reimburse the Indemnifying Party promptly upon demand therefor for all expenses incurred or payment made by such Indemnifying Party in connection with such claim.

11.3 No Liability for Contractors’ Work. (a) Company and Sumitomo acknowledge that a significant portion of the Services will be carried out by Project Contractors under the Project Contracts.

11.4 Limitation of Liability. An Indemnifying Party shall not be liable for any incidental, consequential, special, indirect or punitive damages, including but not limited to, loss of profit, loss of use, loss of opportunity, loss of production or products, regardless of the theory upon which the liability is premised.

All policies shall contain specific provisions that Company’s policy shall be primary in all instances regardless of like coverage, if any, carried by Manager.
