Seller agrees to indemnify and hold harmless Buyer and its directors, officers and employees against and in respect of any and all loss, liability, obligation, damage, deficiency or expense resulting from (a) any misrepresentation, breach of any warranty or non- fulfillment of any agreement of Seller under the terms of this Agreement or in any agreement or certification furnished pursuant hereto and (b) any actions, suits, proceedings, demands, judgments, costs and reasonable legal, investigatory and other expenses incident to any of the foregoing (regardless of whether, in the case of third party actions, suits or proceedings, Seller may have a meritorious defense). Section 5.2 Indemnification by Buyer. Buyer agrees to indemnify and hold harmless Seller and its directors, officers and employees against and in respect of any and all loss, liability, obligation, damage, deficiency or expense resulting from (a) any misrepresentation, breach of any warranty or non- fulfillment of any agreement of Buyer under the terms of this Agreement or in any statement or certification furnished pursuant hereto; and (b) any actions, suits, proceedings, demands, judgments, costs and reasonable legal, investigatory and other expenses incident to any of the foregoing (regardless of whether, in the case of third party actions, suits or proceedings, Buyer may have a meritorious defense). Section 5.3 Procedure. Promptly after receipt by any person that is entitled to indemnification under this Section 5 (the "Indemnified Party") of notice of the commencement of any action in respect of which the Indemnified Party will seek indemnification hereunder, the Indemnified Party shall notify the person obligated to provide such indemnification (the 21 "Indemnifying Party") thereof in writing, but any failure to so notify the Indemnifying Party shall not relieve the Indemnifying Party from any liability that it may have to the Indemnified Party under this Section 5, except to the extent that the Indemnifying Party is prejudiced by the failure to give such notice. The Indemnifying Party shall be entitled to participate in the defense of such action and to assume control of such defense with counsel reasonably satisfactory to such Indemnified Party; provided, however, that: (a) the Indemnified Party shall be entitled to participate in the defense of such claim and to employ counsel at its own expense to assist in the handling of such claim; (b) the Indemnifying Party shall obtain the prior written approval of the Indemnified Party before entering into any settlement of such claim or ceasing to defend against such claim, if pursuant to or as a result of such settlement or cessation, injunctive or other equitable relief would be imposed against the Indemnified Party or the Indemnified Party would be adversely affected thereby; (c) the Indemnifying Party shall not consent to the entry of any judgment or enter into any settlement that does not include as an unconditional term thereof the giving by each claimant or plaintiff to the Indemnified Party of a release from all liability in respect of such claim; and (d) the Indemnifying Party shall not be entitled to control the defense of any claim unless within 15 days after receipt of such written notice from the Indemnified Party the Indemnifying Party confirms in writing its responsibility for such defense and reasonably demonstrates that it will be able to pay the full amount of the reasonably expected liability in connection with any such claim. 22 After written notice by the Indemnifying Party to the Indemnified Party of its election to assume control of the defense of any such action in accordance with the foregoing, (i) the Indemnifying Party shall not be liable to such Indemnified Party hereunder for any expenses subsequently incurred by such Indemnified Party in connection with the defense thereof, and (ii) as long as the Indemnifying Party is reasonably contesting such action in good faith, the Indemnified Party shall not admit any liability with respect to, or settle, compromise or discharge the claim underlying such action without the Indemnifying Party's prior written consent. If the Indemnifying Party elects to so participate in or assume the defense of any such action, the Indemnified Party shall cooperate with the Indemnifying Party in connection with the defense. If the Indemnifying Party does not assume control of the defense of such claim as provided in this Section 5, the Indemnified Party shall have the right to defend and/or settle such claim in such manner as it may deem appropriate at the cost and expense of the Indemnifying Party, and the Indemnifying Party will promptly reimburse the Indemnified Party therefor in accordance with this Section 5. The reimbursement of fees, costs and expenses required by this Section 5 shall be made by periodic payments during the course of the investigation or defense, as and when bills are received or expenses incurred. Section 5.4 Related Matters. (a) Without prejudice to any remedies available to it by law or otherwise, Buyer shall have the right to offset against any payments or other consideration payable by it to Seller after the date of this Agreement pursuant to the terms hereof any claims that Buyer may have against Seller for any breach of any representations, warranties or undertakings. 23 (b) In the event that an Indemnifying Party shall be obligated to indemnify the Indemnified Party pursuant to this Section 5, an Indemnifying Party shall, upon payment of such indemnity in full, be subrogated to all rights of the Indemnified Party with respect to the claims to which such indemnification relates. In the event that an Indemnified Party becomes entitled to any indemnification from an Indemnifying Party, such indemnification shall be made in cash upon demand. Seller shall not be entitled to any contribution or reimbursement from Arisur or Minera Andacaba with respect to payments made by Seller under this Section 5.
