If any claim or liability (a "Third-Party Claim") should be asserted against any of the Seller Indemnified Parties (the "Indemnitee") by a third party after the Closing for which Purchaser have an indemnification obligation under the terms of Section 11.1, then the Indemnitee shall notify Purchaser and Leasco (the "Indemnitor") within 20 days after the Third-Party Claim is asserted by a third party (said notification being referred to as a "Claim Notice") and give the Indemnitor a reasonable opportunity to take part in any examination of the books and records of the Indemnitee relating to such Third-Party Claim and to assume the defense of such Third-Party Claim and in connection therewith and to conduct any proceedings or negotiations relating thereto and necessary or appropriate to defend the Indemnitee and/or settle the Claim. The expenses (including reasonable attorneys' fees) of all negotiations, proceedings, contests, lawsuits or settlements with respect to any Third-Party Claim shall be borne by the Indemnitor. If the Indemnitor agrees to assume the defense of any Third-Party Claim in writing within 20 days after the Claim Notice of such Third-Party Claim has been delivered, through counsel reasonably satisfactory to Indemnitee, then the Indemnitor shall be entitled to control the conduct of such defense, and any decision to settle such Third-Party Claim, and shall be responsible for any expenses of the Indemnitee in connection with the defense of such Third-Party Claim so long as the Indemnitor continues such defense until the final resolution of such Third-Party Claim. The Indemnitor shall be responsible for paying all settlements made or judgments entered with respect to any Third-Party Claim the defense of which has been assumed by the Indemnitor. Except as provided on subsection (b) below, both the Indemnitor and the Indemnitee must approve any settlement of a Third Party Claim. A failure by the Indemnitee to timely give the Claim Notice shall not excuse Indemnitor from any indemnification liability except only to the extent that the Indemnitor is materially and adversely prejudiced by such failure. 10 (b) Failure to Defend. If the Indemnitor shall not agree to assume the defense of any Third-Party Claim in writing within 20 days after the Claim Notice of such Third-Party Claim has been delivered, or shall fail to continue such defense until the final resolution of such Third-Party Claim, then the Indemnitee may defend against such Third-Party Claim in such manner as it may deem appropriate and the Indemnitee may settle such Third-Party Claim on such terms as it may deem appropriate. The Indemnitor shall promptly reimburse the Indemnitee for the amount of all settlement payments and expenses, legal and otherwise, incurred by the Indemnitee in connection with the defense or settlement of such Third-Party Claim. If no settlement of such Third-Party Claim is made, then the Indemnitor shall satisfy any judgment rendered with respect to such Third-Party Claim before the Indemnitee is required to do so, and pay all expenses, legal or otherwise, incurred by the Indemnitee in the defense against such Third-Party Claim. 11.3 Non-Third-Party Claims.

A failure by Indemnitee to timely give the foregoing notice to Purchaser shall not excuse Purchaser from any indemnification liability except to the extent that Purchaser is materially and adversely prejudiced by such failure. 10. Survival. Except as otherwise provided in this Section 11.4, all representations and warranties made by Purchaser, Leasco and Seller in connection with this Agreement shall survive the Closing.

This Agreement may be executed in one or more counterparts, with the same effect as if all parties had signed the same document. Each such counterpart shall be an original, but all such counterparts taken together shall constitute a single agreement. In the event that any signature is delivered by facsimile transmission, such signature shall create a valid and binding obligation of the party executing (or on whose behalf such signature is executed) the same with the same force and effect as if such facsimile signature page was an original thereof. 13 12.10 Section Headings and Gender.

Each of Seller, Purchaser and Leasco acknowledges and agrees that Gran Tierra would be damaged irreparably if any provision of this Agreement is not performed in accordance with its specific terms or is otherwise breached. Accordingly, each of Seller, Purchaser and Leasco agrees that Gran Tierra will be entitled to seek an injunction or injunctions to prevent breaches of the provisions of this Agreement and to enforce specifically this Agreement and its terms and provisions in any action instituted in any court of the United States or any state thereof having jurisdiction over the parties and the matter, subject to Section 12.8, in addition to any other remedy to which they may be entitled, at law or in equity. Except as expressly provided herein, the rights, obligations and remedies created by this Agreement are cumulative and in addition to any other rights, obligations or remedies otherwise available at law or in equity, and nothing herein will be considered an election of remedies. 12.12 Construction. The parties hereto have participated jointly in the negotiation and drafting of this Agreement. If an ambiguity or question of intent or interpretation arises, this Agreement will be construed as if drafted jointly by the parties hereto and no presumption or burden of proof will arise favoring or disfavoring any party because of the authorship of any provision of this Agreement. Any reference to any federal, state, local, or foreign law will be deemed also to refer to law as amended and all rules and regulations promulgated thereunder, unless the context requires otherwise. The words "include," "includes," and "including" will be deemed to be followed by "without limitation." The words "this Agreement," "herein," "hereof," "hereby," "hereunder," and words of similar import refer to this Agreement as a whole and not to any particular subdivision unless expressly so limited. The parties hereto intend that each representation, warranty, and covenant contained herein will have independent significance. If any party hereto has breached any representation, warranty, or covenant contained herein in any respect, the fact that there exists another representation, warranty or covenant relating to the same subject matter (regardless of the relative levels of specificity) which that party has not breached will not detract from or mitigate the fact that such party is in breach of the first representation, warranty, or covenant.
