(iii) Buyer Parties shall have the right to conduct title due diligence with respect to the Real Property. If any Title Curative Work is determined by any Buyer Party to be required prior to the Closing and the reasonably estimated cost of such Title Curative Work exceeds $50,000, then Buyer Parties may:

(B) Except as provided in Section 6.3(b)(vi)(A) above, the Buyer Parties or the Companies shall have no right or remedy after the Closing to seek reimbursement of, or claim any damages, losses, fees or expenses from, Seller for any other Title Curative Work that any Buyer Party voluntarily commences or causes to be commenced, but Seller shall indemnify and hold each Buyer Party and each Buyer Party’s Affiliates (including the Companies) and their respective officers, directors, partners, members, employees and agents thereof harmless from and against any and all Losses arising out of, based upon, attributable to or resulting from any third party claim or assertion that Title Curative Work is required, or any Title Curative Work arising out of or resulting from such third party claim or assertion, pursuant to the provisions of Section 11.1 of this Agreement.

(d) Removal of Seller’s Name. Within 180 days after the Closing Date, Buyer Parties shall remove or cause to be removed the name Rio Vista or any variations and derivations thereof or logos relating thereto from the Assets (including all pipeline markers) and Buyer Parties shall not thereafter make any use whatsoever of such names or logos. Notwithstanding anything herein to the contrary, Seller’s exclusive remedy for Buyer Parties’ failure to comply with the provisions of this Section 6.3(e) shall be for Buyer Parties to pay to Seller $500 for each day after the expiration of such 180-day period that it fails to comply.

(A) allow Seller additional time prior to Closing (as determined by Buyer Parties) in which to undertake actions sufficient, in the reasonable judgment of Buyer Parties, to remedy any such Environmental Condition or violation of Environmental Law, in which case the Closing shall be postponed by such additional time period;

(B) attempt to negotiate with Seller a reduction in the Purchase Price so as to compensate Buyer Parties for costs and damages which may be associated with any such Environmental Condition or violation of Environmental Law; or

(iv) If Seller is unable or unwilling to remedy any such Environmental Condition or violation of Environmental Law or if Seller and Buyer Parties are unable to reach an agreement as contemplated under subsections (B) or (C) above, then either Buyer Parties or Seller may terminate this Agreement without any further obligation or liability of any Party hereto except the obligations set out in Section 3.1(e).

(ii) Any and all liabilities for severance payments and other amounts owed with respect to any employees (including all obligations under applicable Seller Plans) whose employment with Seller, the Companies and their Affiliates is terminated on or before the Closing for any reason whatsoever shall remain the responsibility of Seller.

Nothing in this Agreement shall require or be construed or interpreted as requiring any Buyer Party or its Affiliates to continue the employment of any of their employees following the Closing Date, or to prevent any Buyer Party or its Affiliates from changing the terms and conditions of employment (including compensation and benefits) of any of their employees following the Closing Date. Without limiting the generality of Section 12.4, this Section 6.3(g) is not intended to confer upon any Business Employee or any other employee of the Seller, the Companies or its Affiliates any rights or remedies hereunder.

No representation or warranty contained in this Agreement shall be deemed breached as of the date of the making of such representation or warranty by reason of the fact that the relevant schedule was incomplete as of such date provided that a complete schedule that renders true such representation or warranty is delivered pursuant to this Section 6.3(h) at least five Business Days before the Closing.

ARTICLE VII
TAX MATTERS

SECTION 7.1 Preparation and Filing of Tax Returns.

(a) Seller shall prepare or cause to be prepared all Tax Returns of the Companies for all periods ending on or prior to the Closing Date that are due after the Closing Date; provided, however, that if Seller fails to prepare any Tax Returns for Taxes for which Buyer Parties are indemnified under this Article VII within thirty (30) days following notice from any Buyer Party that such Tax Return should be prepared, the Buyer Party shall be entitled to prepare (or cause to be prepared) the Tax Returns with respect to such Taxes. Any Tax Returns described in the preceding sentence shall be prepared on a basis consistent with the past practices of the Companies except as otherwise required by Law. The preparing party shall deliver a copy of each such Tax Return to Buyer Parties and Seller at least 30 days prior to the due date (including extensions) for filing such Tax Return, and no such Tax Returns shall be filed without Buyer Parties’ prior written consent (not to be unreasonably withheld). Buyer Parties shall cause the Companies to timely file such Tax Returns and Seller shall pay or reimburse Buyer Parties for all Taxes due with respect to such Tax Returns, such payment or reimbursement to occur at least 5 days prior to the filing of such Tax Returns.

(b) With respect to any Tax Return covering a taxable period beginning on or before the Closing Date and ending after the Closing Date (a “Straddle Period Tax Return”) that is required to be filed after the Closing Date with respect to the Companies, Buyer Parties shall cause such Tax Return to be prepared in a manner consistent with practices followed in prior years, except as otherwise required by Law, shall cause to be included in such Tax Return all items of income, gain, loss, deduction or credit (“Tax Items”) required to be included therein, and at least 30 days prior to the due date (including extensions) of such Tax Return shall furnish a copy of such Tax Return to Seller. Buyer Parties shall permit Seller to review and comment on such Tax Return. Buyer Parties shall cause the Companies or the relevant Company to timely file such Tax Return with the appropriate Taxing Authority, and shall be responsible for the payment of all Taxes due with respect to the Post-Closing Tax Period covered by such Tax Return and Seller shall pay or reimburse Buyer Parties for all Taxes due with respect to the Pre-Closing Tax Period covered by such Tax Return, such payment or reimbursement to occur at least 5 days prior to the filing of such Tax Returns.

(c) In the case of any Straddle Period: (i) real, personal and intangible property Taxes (“Property Taxes”) of the Company for the Pre Closing Tax Period shall equal the Property Taxes owed by each entity for such Straddle Period multiplied by a fraction, the numerator of which is the number of days during the Straddle Period that are in the Pre Closing Tax Period and the denominator of which is the number of days in the Straddle Period; and (ii) Taxes of the Company, other than Property Taxes, for the Pre-Closing Tax Period shall be computed as if the entire Straddle Period ended as of the close of business on the Closing Date.

(d) If, after the Closing Date, any Buyer Party or any of the Companies receives a refund or utilizes a credit of any Tax attributable to a Pre-Closing Tax Period, such Buyer Party shall pay to Seller within ten Business Days after such receipt an amount equal to such refund received or credit utilized (or so much of such refund or credit as relates to the portion of the taxable period ending on or before Closing Date), together with any interest received or credited thereon; provided, however, that the Seller shall be required to indemnify the Buyer Parties and the Companies for any Taxes subsequently determined to be owing with respect to any such refund or credit. Notwithstanding the foregoing, any such refund or credit shall be for the account of the applicable Buyer Party to the extent that such refund or credit is attributable (determined on a marginal basis) to the carryback from a Post-Closing Tax Period (or the portion of a Straddle Period that begins on the date after the Closing Date) of items of loss, deductions or other Tax items of any Company (or any of its Affiliates, including Buyer Parties). Any refund or credit of Taxes of any Company for any Post Closing Tax Period shall be for the account of the applicable Buyer Party. Any refund or credit of Taxes of any Company for any Straddle Period shall be equitably apportioned between the Seller on the one hand, and the applicable Buyer Party on the other hand (as determined in accordance with Section 7.1(d)). Each party shall, or shall cause its Affiliates to, forward to any other party entitled under this Section 7.1(e) to any refund or credit of Taxes any such refund within ten (10) days after such refund is received or reimburse such other party for any such credit within ten (10) days after the credit is allowed or applied against another Tax liability; provided, however, that any such amounts shall be net of any Tax cost or benefit to the payor party attributable to the receipt of such refund and/or the payment of such amounts to the payee party. The parties shall treat any payments under this section as an adjustment to the Purchase Price, unless, and then only to the extent, otherwise required by a Final Determination.

SECTION 7.2 Access to Information.

(a) After the Closing Date, Seller shall grant to Buyer Parties (or applicable designees) access at all reasonable times to all of the Books and Records relating to the Companies within the possession of Seller (including work papers and correspondence with taxing authorities), and shall afford Buyer Parties (or applicable designees) the right (at Buyer Parties’ expense) to take extracts therefrom and to make copies thereof, to the extent reasonably necessary to permit Buyer Parties (or applicable designees) to prepare Tax Returns, to conduct negotiations with Taxing Authorities, and to implement the provisions of, or to investigate or defend any claims between the Parties arising under, this Agreement.

(b) After the Closing, Buyer Parties shall grant or cause the Companies to grant to Seller (or its designees) access at all reasonable times to all of the Books and Records relating to the Companies within the possession of Buyer Parties or the Companies (including work papers and correspondence with Taxing Authorities), and shall afford Seller (or its designees) the right (at Seller’s expense) to take extracts therefrom and to make copies thereof, to the extent reasonably necessary to permit Seller (or its designees) to prepare Tax Returns, to conduct negotiations with Tax Authorities, and to implement the provisions of, or to investigate or defend any claims between Buyer Parties and Seller arising under, this Agreement.

(c) Each Buyer Party and Seller will preserve and retain all Books and Records, as applicable, relating to any Tax Returns of or with respect to the Companies or to any claims, audits or other proceedings affecting the Companies until the expiration of the statute of limitations (including extensions) applicable to the taxable period to which such documents relate or until the final determination of any controversy with respect to such taxable period, and until the final determination of any payments that may be required with respect to such taxable period under this Agreement.

SECTION 7.3 Seller’s Tax Indemnification.

(a) From and after the Closing, Seller shall be liable for, and shall indemnify each Buyer Party and its officers, directors, partners, shareholders, members, employees, agents and representatives against and hold them harmless from (i) all liability for Taxes of the Companies with respect to any Pre-Closing Tax Period, (ii) for the portion of any Straddle Period ending at the close of business on the Closing Date (as determined in accordance with Section 7.1(d)); (iii) Taxes imposed on any Company as a result of being a member of a consolidated, combined, unitary or similar group prior to the Closing Date, by reason of the liability of any of the Companies pursuant to U.S. Treasury Regulation Section 1.1502-6(a) (or any predecessor or successor thereof or any analogous or similar provision under state, local or foreign Law); (iv) all liability for Taxes of the Companies arising (directly or indirectly) as a result of the transactions contemplated pursuant to this Agreement, (v) any breach of any representation or warranty contained in Section 4.10 hereof or covenant contained in Section 6.1(a)(vi) hereof or this Article VII, (vi) any Liability for Taxes attributable to or imposed upon Seller or its Affiliates, or attributable to or imposed upon the Assets for the Pre-Closing Tax Period, including any transfer Taxes described in Section 7.8, and (vii) all liability for reasonable legal fees and expenses attributable to any item in the foregoing clauses.

(b) The Seller’s indemnity obligation under this Section 7.3 in respect of Taxes for a Straddle Period shall initially be satisfied by a payment to Buyer Parties, or at Buyer Parties’ direction, to any Company of the excess of (i) such Taxes for the Pre Closing Tax Period, over (ii) the amount of such Taxes paid by the Seller or any of its Affiliates (other than the Companies) at any time, plus the amount of such Taxes paid by the Companies on or prior to the Closing Date. Such excess initially shall be paid no later than ten (10) days prior to the date on which the Tax Return with respect to the final liability for such Taxes is required to be filed. If the amount of such Taxes paid by the Seller or any of its Affiliates (other than the Companies)

at any time, plus the amount of such Taxes paid by the Companies on or prior to the Closing Date, exceeds the amount payable pursuant to the preceding sentence, the Companies shall pay to the Seller the amount of such excess (A) in the case of Property Taxes, at the Closing pursuant to a deduction from the Purchase Price, and (B) in all other cases, within ten (10) days after the Tax Return with respect to the final liability for such Taxes is required to be filed. The payments to be made pursuant to this Section 7.3(b) with respect to a Straddle Period shall be appropriately adjusted to reflect any Final Determination with respect to Straddle Period Taxes. Payments due under this Article VII are not subject to the provisions of Section 11.4(a).

(c) Any indemnity payment to be made under this Section 7.3, other than an indemnity payment described in the immediately preceding Section 7.3(c), shall be paid within ten (10) days after the indemnified party makes written demand upon the indemnifying party, but in no case earlier than five (5) Business Days prior to the date on which the relevant Taxes are required to be paid to the relevant Tax Authority (including as estimated Tax payments). Buyer Parties’ and the Seller’s indemnity obligations under Articles XI and VII of this Agreement shall be (i) increased to reflect any Tax cost incurred by the indemnified party or any of its Affiliates as a result of the receipt or accrual of the indemnity payment and (ii) reduced to reflect any Tax Benefit realized, in the year in which the indemnity payment is required to be made or in any prior year, by the indemnified party or any of its Affiliates.

SECTION 7.4 Tax Indemnification Procedures.

(a) If a claim (“Tax Indemnified Claim”) shall be made by any Taxing Authority that, if successful, would result in the indemnification of a Party under this Agreement (referred to herein as the “Tax Indemnified Party”), the Tax Indemnified Party shall promptly notify the party obligated under this Agreement to so indemnify (referred to herein as the “Tax Indemnifying Party”) in writing of such fact. Failure to give notice of a Tax Claim to the Tax Indemnifying Party within a sufficient period of time and in reasonably sufficient detail to allow the Tax Indemnifying Party to effectively contest such Tax Claim shall affect the liability of the Tax Indemnifying Party to any Tax Indemnified Party only to the extent that the Tax Indemnifying Party’s position is actually and materially prejudiced as a result thereof.

(b) Seller shall control all proceedings taken in connection with any Tax Claim relating solely to Taxes of the Companies for a Pre-Closing Tax Period, and may make all decisions in connection with such Tax Claim; provided, however, that (A) each Buyer Party and counsel of its own choosing shall have the right to participate fully in all aspects of the prosecution or defense of such Tax Claim, and (B) Seller shall not settle any such Tax Claim without the prior written consent of Buyer Parties (not to be unreasonably withheld). The Seller and Buyer Parties shall jointly control all proceedings taken in connection with any Tax Claim relating solely to Taxes of the Companies for a Straddle Period, and neither party shall settle any such Tax Claim without the prior written consent of the other party (not to be unreasonably withheld); provided, however, that each Buyer Party and its Affiliates shall have sole control of any such Tax Claim arising with respect to any Tax Return filed by any Buyer Party or an Affiliate on an affiliated, consolidated, combined or unitary group basis. Buyer Parties shall control all proceedings with respect to all other Tax Claims.

(c) If, after actual receipt by the Tax Indemnified Party of an amount advanced by the Tax Indemnifying Party pursuant to this Section 7.4, the extent of the liability of the Tax Indemnified Party with respect to the claim shall be established by a Final Determination, the Tax Indemnified Party shall promptly repay to the Tax Indemnifying Party the amount advanced to the extent of any refund received by the Tax Indemnified Party with respect to the claim together with any interest received thereon from the applicable Taxing Authority and any recovery of legal fees from such Taxing Authority, net of any Taxes as are required to be paid by the Tax Indemnified Party with respect to such refund, interest or legal fees (calculated at the maximum applicable statutory rate of Tax in the year of recovery without regard to any other Tax Items).

SECTION 7.5 Tax Characterization.

(a) The purchase of the Shares by TMOC and TLP MEX shall be reported by the Parties for United States federal income tax purposes and related state income tax purposes in accordance with Rev.

Any indemnity payment made pursuant to this Agreement shall be treated as an adjustment to the Purchase Price for Tax purposes, unless, and then only to the extent, otherwise required by a Final Determination.

SECTION 7.8 Transfer Taxes. Seller will bear the cost of any documentary, stamp, sales, value added, transfer, excise, other Taxes or governmental charges imposed by any Tax Authority, domestic or foreign, and all recording or filing fees, notarial fees and other similar costs (if any) payable in respect of this Agreement or the transactions contemplated hereby.

ARTICLE XI
INDEMNIFICATION

SECTION 11.1 Seller Indemnification.

(a) Subject to the limitations set forth in this Article XI, if the Closing occurs, then from and after the Closing Date Seller shall indemnify and hold Buyer Parties and Buyer Parties’ Affiliates (including the Companies) and their respective officers, directors, partners, members, employees and agents thereof harmless from and against any and all Losses arising out of, based upon, attributable to or resulting from:

(i) any breach of any representation or warranty of Seller contained in Article IV or any inaccuracy in the certificate delivered to Buyer Parties pursuant to Section 8.3,

(ii) any breach of any agreement or covenant on the part of Seller contained in this Agreement,

(iii) any act, event or omission occurring prior to the Closing Date (and not otherwise constituting an Assumed Liability) in the conduct by Seller or any of the Companies of the Business, including, without limitation, legal, labor, environmental, contractual, regulatory, tax, title and ownership issues,

(iv) the Retained Liabilities,

(v) any Legal Proceedings identified on Schedule 4.7,

(vi) any amounts for which the Buyer Parties are indemnified by the Seller pursuant to Section 6.3(b)(vi)(A) or (B), and

(vii) any amounts the Seller is obligated to pay pursuant to Section 6.3(g)(ii).

(b) The foregoing shall not apply to any breach of Seller’s representations and warranties set forth in Section 4.10, or to any breach of any covenants set forth in Article VII, it being agreed and understood that the Buyer’s sole and exclusive remedies for any matters relating to Taxes shall be as provided in Articles VII.

SECTION 11.2 Buyer Parties Indemnification.

(a) Subject to the limitations set forth in this Article XI, if the Closing occurs, then from and after the Closing Date Buyer Parties shall indemnify and hold Seller and Seller’s Affiliates and their respective officers, directors, members, partners, employees and agents thereof harmless from and against any and all Losses arising out of, based upon, attributable to or resulting from:

(i) any breach of any representation or warranty of Buyer Parties contained in Article V or any inaccuracy in the certificate delivered to Seller pursuant to Section 9.3,

(ii) the breach of any agreement or covenant on the part of Buyer Parties contained in this Agreement,

(b) The foregoing shall not apply to any breach of Buyer Parties’ covenants set forth in Article VII, it being agreed and understood that Seller’s sole and exclusive remedies for matters relating to Taxes shall be as provided in Article VII.

SECTION 11.3 Indemnification Procedures. If any third Person (i.e., a Person other than a Party or any Affiliate of a Party) asserts any claim against a Party which, if successful, would entitle the Party to indemnification under this Article XI (the “Indemnified Party”), it shall give notice of such claim to the Party from whom it intends to seek indemnification (the “Indemnifying Party”) and the Indemnifying Party shall have the right to assume the defense of such claim at its expense. If the Indemnifying Party does assume such defense, it shall indemnify and hold the Indemnified Party harmless from and against any and all Losses caused by or arising out of any settlement or judgment of such claim. In addition, the Indemnified Party shall have the right to participate in the defense of such claim at its expense, in which case (a) the Indemnifying Party shall cooperate in providing information to and consulting with the Indemnified Party about the claim, and (b) the Indemnifying Party shall not consent to the entry of judgment or enter into any settlement without the prior written consent of the Indemnified Party, which shall not be unreasonably withheld. If the Indemnifying Party fails to assume the defense of any such claim, the Indemnified Party may defend against or settle such claim and the Indemnifying Party shall be liable for any settlement of any such claim.

SECTION 11.4 Limits on Indemnification. Notwithstanding anything to the contrary contained in this Agreement:

(a) Seller shall not have any obligation to provide indemnification for Losses pursuant to Section 11.1 except to the extent that the aggregate amount of all such Losses exceeds $100,000 (the “Basket Amount”), in which case Seller shall be liable to Buyer Parties only for such Losses in excess of $100,000. The maximum obligation of Seller to provide indemnification for all Losses pursuant to Section 11.1 shall be limited to an amount equal to the Purchase Price; provided, however, that the maximum obligation of Seller to provide indemnification with respect to amounts payable under Section 6.3(b)(vi) (including any such amounts paid from the Holdback Amount) shall be limited to an amount equal to US$1,000,000. Notwithstanding the foregoing, the Basket Amount will not apply with respect to any breach of Seller’s representations and warranties set forth in Sections 4.1, 4.2, 4.3, 4.4, 4.5, 4.8, 4.9, 4.11, 4.13, 4.16, 4.18 and 4.19, the breach of any representations and warranties caused by fraud or Seller’s intentional misconduct, any Losses related to the Legal Proceedings set forth in Schedule 4.7, amounts for which the Buyer Parties are indemnified pursuant to Sections 6.3(b)(vi)(A) or amounts which the Seller is obligated to pay pursuant to Section 6.3(g)(ii).

(b) Buyer Parties shall not have any obligation to provide indemnification for Losses indemnified pursuant to Section 11.2 except to the extent that the aggregate amount of all such Losses exceeds the Basket Amount, in which case Buyer Parties shall be liable to Seller only for such Losses in excess of the Basket Amount. The maximum obligation of Buyer Parties to provide indemnification for Losses pursuant to Section 11.2 shall be limited to an amount equal to the Purchase Price. Notwithstanding the foregoing, the Basket Amount will not apply with respect to any breach of Buyer Parties’ representations and warranties set forth in Sections 5.1, 5.2, 5.3, 5.5 and 5.7.

(c) Seller shall not have any obligation to provide indemnification hereunder for any Losses pursuant to Sections 11.1 unless a written notice of claim specifying in reasonable detail the specific nature and basis of the Losses and the estimated amount of such Losses is delivered to Seller at any time prior to 5:00 p.m., El Segundo, California time, on the last day of the applicable survival period set forth with respect to such claim under Section 11.5. Buyer Parties shall not have any obligation to provide indemnification hereunder for any Losses unless a written notice of claim specifying in reasonable detail the specific nature and basis of the Losses and the estimated amount of such Losses is delivered to Buyer Parties at any time prior to 5:00 p.m., El Segundo, California time, on the last day of the applicable survival period set forth with respect to such claim under Section 11.5.

(d) For purposes of determining Losses in order to calculate the Basket Amount and determine rights to indemnification under this Article XI, the representations and warranties set forth in Articles IV and V shall be read without giving effect to any Materiality Requirement set forth therein. As used in this Agreement, a “Materiality Requirement” shall mean any requirement in a representation or warranty that a condition, event or state of fact be “material,” correct or true in “all material respects,” have a “Material Adverse Change” or “Material Change,” or be or not be “reasonably expected to have a Material Change” (or other words or phrases of similar effect or impact) in order for such condition, event or state of facts to cause such representation or warranty to be inaccurate.

(e) The Parties agree that the Holdback Amount shall serve as security for the indemnification obligations of Seller under this Article XI, under Article VII and under other applicable provisions of this Agreement. Buyer Parties may elect to be paid for any such Losses, to the extent funds are available therein, from the Holdback Amount; provided, however, that to the extent that the amounts owing to Buyer Parties exceed the amount of the Holdback Amount then available to pay such amounts, Seller shall pay such excess amount to Buyer Parties directly by wire transfer of immediately available funds from Seller to an account designated by Buyer Parties, within ten (10) days after the determination thereof.

SECTION 11.5 Survival. The representations, warranties, covenants and agreements of the Parties set forth herein or in any certificate delivered pursuant to the terms hereof shall survive the Closing for a period of three years; provided, however, that (a) the covenants in respect of Title Curative Work under Section 6.3(b)(vi) shall survive the Closing for a period of five years; and (b) the representations and warranties of Seller set forth in (i) Sections 4.1, 4.2, 4.4 and 4.19 shall survive indefinitely and (ii) Sections 4.8, 4.9 and 4.10 shall survive for the applicable statute of limitations period, plus sixty days. Such representations and warranties shall be subject to the provisions of Articles VII and XI.

SECTION 11.6 Certain Damages. NEITHER PARTY NOR ANY OF THEIR RESPECTIVE AFFILIATES OR REPRESENTATIVES SHALL BE LIABLE TO THE OTHER PARTY OR TO ANY OF ITS AFFILIATES OR REPRESENTATIVES FOR PUNITIVE, SPECIAL, EXEMPLARY, INCIDENTAL, INDIRECT, CONSEQUENTIAL, REMOTE OR SPECULATIVE DAMAGES IN CONNECTION WITH THIS AGREEMENT AND THE TRANSACTION CONTEMPLATED HEREBY, REGARDLESS OF WHETHER SUCH DAMAGES ARE BASED ON CONTRACT, TORT, STRICT LIABILITY, VIOLATION OF LAW, OR ANY OTHER LEGAL OR EQUITABLE PRINCIPLE; PROVIDED, THE FOREGOING SHALL NOT APPLY TO ANY SUCH DAMAGES FINALLY DETERMINED TO BE PAYABLE TO A THIRD PERSON PURSUANT TO A CLAIM COVERED BY THE INDEMNITY PROVIDED PURSUANT TO ARTICLE XI.

SECTION 11.7 Exclusive Remedy. Except for the tax indemnification provisions of Article VII, if the Closing occurs, the sole and exclusive remedy of each of Buyer Parties and Buyer Parties’ Affiliates, and Seller and Seller’s Affiliates, with respect to the purchase and sale of the Assets, the Fee Properties, the Shares and the Tergas Option shall be pursuant to the express indemnification provisions of this Article XI and any and all (a) claims relating to the representations, warranties, covenants and agreements contained in this Agreement, (b) other claims pursuant to or in connection with this Agreement, or (c) other claims relating to the Assets, the Fee Properties, the Shares and the Tergas Option shall be subject to the provisions set forth in this Article XI.

Except for claims made pursuant to the express indemnification provisions of this Article XI, Buyer Parties on behalf of each of Buyer Parties and Buyer Parties’ Affiliates shall be deemed to have waived, to the fullest extent permitted under applicable law, any right of contribution against Seller and Seller’s Affiliates and any and all rights, claims and causes of action it may have against Seller or any of Seller’s Affiliates, arising under or based on any federal, state or local statute, law, ordinance, rule or regulation or common law or otherwise.

Except for claims made pursuant to the express indemnification provisions of this Article XI, Seller on behalf of each of Seller or any of Seller’s Affiliates shall be deemed to have waived, to the fullest extent permitted under applicable law, any right of contribution against Buyer Parties or any of Buyer Parties’ Affiliates and any and all rights, claims and causes of action it may have against Buyer Parties or any of Buyer Parties’ Affiliates, arising under or based on any federal, state or local statute, law, ordinance, rule or regulation or common law or otherwise.

Unless otherwise expressly provided in this Agreement, no delay or omission on the part of any Party in exercising any right or privilege under this Agreement shall operate as a waiver thereof, nor shall any waiver on the part of any Party of any right or privilege under this Agreement operate as a waiver of any other right or privilege under this Agreement, nor shall any single or partial exercise of any right or privilege preclude any other or further exercise thereof or the exercise of any other right or privilege under this Agreement.

Each Party hereby irrevocably waives, to the fullest extent it may effectively do so, the defense of an inconvenient forum to the maintenance of such action or proceeding. The Parties further agree, to the extent permitted by Law, that final and un-appealable judgment against any of them in any action or proceeding contemplated above shall be conclusive and may be enforced in any other jurisdiction within or outside the United States by suit on the judgment, a certified copy of which shall be conclusive evidence of the fact and amount of such judgment. Each Party waives, to the fullest extent permitted by applicable Law, any right it may have to a trial by jury in respect of any action, suit or proceeding arising out of or relating to this Agreement. Each Party certifies that it has been induced to enter into this Agreement by, among other things, the mutual waivers set forth in this Section 12.7.
