(v)                                 the amount of the Option Costs.

No earlier than five business days and no later than two business days prior to the Closing Date, the Sellers shall provide to the Buyer a statement setting out a good faith estimate of this calculation (the “Adjusted Purchase Price Notice”) which shall specify the Adjusted Purchase Price payable at Closing, subject to adjustment on the basis described in Section 2.4 below.  Attached to this Agreement is Schedule 2.3 which illustrates the calculation of the Adjusted Purchase Price based on Cash, Current Assets, Current Liabilities, Debt as shown in Trace’s consolidated balance sheet at June 30, 2005 and other estimated amounts.  Schedule 2.3 is included to assist the Sellers in preparing the Adjusted Purchase Price Notice and the parties in completing any adjustments pursuant to Section 2.4.

The difference between CDN$33,000,000 and the Adjusted Purchase Price shall be applied at the Closing Time by the Buyer (or by Trace, upon payment of the required funds to Trace by the Buyer), in the following order of priority, to pay the full amount of the Transaction Costs, the Option Costs, the I/O Option Cost, and to reduce the Debt (in the case of the Debt, to the extent any such funds remain).

Section 2.4                                   Post Closing Adjustment.

(a)                                  Within 45 days of the Closing Date, the Buyer and each of the Sellers shall have the right to review the books and records of the Corporations and any other relevant books and records maintained by the Corporations and determine whether the Adjusted Purchase Price

14

Notice is accurate and whether the Adjusted Purchase Price should be altered, based on the Buyer’s or the Sellers’ determination, per good faith calculations, that the value of such items is not accurately represented in the Adjusted Purchase Price Notice.  In the event any of the Parties makes such determination, it shall prepare and deliver to the other Parties a statement setting forth in reasonable detail, such calculation of the amount for which adjustment is provided herein and shall assist the other parties in verifying the amounts set forth in such statements.

(b)                                 Buyer or either of the Sellers may dispute all or any portion of the calculation of the Adjusted Purchase Price Notice and the proposed revised Adjusted Purchase Price by written notice to the other party within 30 days of the date of receipt of the statement referred to in Section 2.4(a) setting forth, in reasonable detail, the basis for the dispute.  If the parties do not agree on the calculation of the adjustment amounts within 15 days of any notice of dispute, the Buyer and the Sellers will select (within 10 days of the expiration of that 15 day period) an accounting firm mutually acceptable to them to resolve any remaining objections.  If the Buyer and the Sellers are unable to agree on the choice of an accounting firm within such 10 day period, they will select, within an additional 10 day period, the Calgary office of a nationally-recognized accounting firm by lot (after excluding their respective regular outside accounting firms) that is qualified to provide an audit opinion in respect of the financial statements of a “reporting issuer”, as that term is defined in Canadian securities law.  The determination of any accounting firm so selected (and the determination it makes pursuant to its power to resolve any objections regarding the Adjusted Purchase Price) will be set forth in writing and will be conclusive and binding upon the Buyer and the Sellers for purposes of determining adjustments to the Purchase Price pursuant to this Section 2.4.  The cost and expense of such accounting firm shall be borne equally by the Buyer and the Sellers.  Such accounting firm shall be engaged on the basis that it will make its determination within 60 days of being selected.

(c)                                  If all of the adjustment amounts are agreed to by the Parties or determined by an appointed accounting firm in accordance with this Section 2.4, as the case may be, and if:

(i)                                     the sum of such adjustments would result in a revised Adjusted Purchase Price (the “Recalculated Value”) which is less in value than the amount of the Adjusted Purchase Price set forth in the Adjusted Purchase Price Notice delivered pursuant to Section 2.3 (the “Original Value”), then the Sellers shall pay to the Buyer the amount of the Original Value less the Recalculated Value within two (2) business days by wire transfer; or

(ii)                                  if the Recalculated Value is greater than the Original Value, then the Buyer shall pay to the Sellers the amount, if any, by which the Recalculated Value is greater than the Original Value within two (2) business days by wire transfer.

(d)                                 any adjustments determined in accordance with this Section 2.4 shall be made in accordance with Canadian GAAP and no adjustment shall be made for changes in the exchange rate for the Canadian dollar in effect after the Closing Date.

(e)                                  The Buyer and the Sellers shall have no remedy whatsoever in respect of any determination of a Recalculated Value, except pursuant to this Section 2.4.

15

Section 2.5                                   Treatment of the Trace Options

(a)                                  Pursuant to those certain agreements by which Trace awarded stock options to the Persons listed in the table under Section 2.5(c) (the “Option Agreements”), at the Closing Time Trace, upon receipt of an executed option termination agreement which terminates all obligations of Trace relating to the Option Agreements in exchange for the payment described herein in a form acceptable to the Buyer acting reasonably, will pay to the Optionholders an amount for each Option equal to the Trace Share Purchase Price (as determined below) less CDN$50 (and Trace shall be entitled to make any withholdings required by applicable law).  The total of these payments shall be the “Option Costs”.  As a result of these payments, all of the Option Agreements will be terminated.  For clarity, the Option Costs shall not be adjusted after Closing, including as a consequence of any post Closing adjustment to the Adjusted Purchase Price.

(b)                                 The “Trace Share Purchase Price” shall be a dollar amount equal to:

(i)                                     the sum of:  (i) Adjusted Purchase Price (calculated without adjustment for the Option Costs), (ii) the Escrow Amount, (iii) the product of 1,000,000 multiplied by the 10 day weighted average trading price of the shares of the common stock of the Buyer before the Closing Date (and converted to Canadian dollars using the Exchange Rate); and (iv) CDN$546,250;

divided by

(ii)                                  279,464.

(c)                                  The Trace Options have been issued as follows:

Section 2.6                                   Closing.

(b)                                 Each of the Corporations have made available to the Buyer true, accurate and complete copies of (i) the documents comprising each Employee Plan (or, with respect to any Employee Plan which is unwritten, a detailed written description of eligibility, participation,

27

benefits, funding arrangements, assets and any other matters which relate to the obligations of each of the Corporations); (ii) all trust agreements, insurance contracts or any other funding instruments related to the Employee Plans; (iii) all rulings, determination letters, no-action letters or advisory opinions from the IRS, the U.S. Department of Labor, the PBGC or any other Governmental Body that pertain to each Employee Plan and any open requests therefor; (iv) the most recent actuarial (if applicable) and financial reports (audited and/or unaudited) and the annual reports filed with any Government Body with respect to the Employee Plans during the current year; (v) all securities registration statements filed with respect to any Employee Plan; (vi) all contracts with third-party administrators, actuaries, investment managers, consultants and other independent contractors that relate to any Employee Plan, and (vii) with respect to any Employee Plans that are subject to Title IV of ERISA, the most recent Form PBGC-1 filed for such plan.

(c)                                  Except as disclosed in Schedule 4.15(c), full payment has been made of all amounts that are required under the terms of each Employee Plan and applicable Legal Requirements to be paid by the Corporations as contributions with respect to all periods prior to and including the last day of the most recent fiscal year of such Employee Plan ended on or before the date of this Agreement and all periods thereafter prior to the Closing Date.  Trace Texas has paid in full all required insurance premiums, subject only to normal retrospective adjustments in the ordinary course, with regard to the Employee Plans for all policy years or other applicable policy periods ending on or before the Closing Date.

(d)                                 With respect to any Employee Pension Benefit Plan and any Employee Welfare Benefit Plan which is sponsored, maintained, or contributed to, or has been sponsored, maintained or contributed to within six years prior to the Closing Date, by the Corporations or any other corporation or trade or business controlled by, controlling or under common control with the Corporations (within the meaning of Section 414 of the Code or Section 4001(a)(14) or 4001(b) of ERISA) (“ERISA Affiliate”), neither Trace Texas nor any ERISA Affiliate has any liability or has Knowledge of any facts or circumstances that might give rise to any liability of the Corporations for, or the imposition of a lien on any of their assets or with respect to any of their assets, and the transactions contemplated hereby will not result in any liability for (i) the termination of or withdrawal from any Employee Pension Benefit Plan under Sections 4062, 4063 or 4064 of ERISA; (ii) any lien imposed under Section 302(f) of ERISA or Section 412(n) of the Code; (iii) any interest payments required under Section 302(e) of ERISA or Section 412(m) of the Code; (iv) any excise tax imposed by Section 4971 of the Code; (v) any minimum funding contributions under Section 302(c)(11) of ERISA or Section 412(c)(11) of the Code; or (vi) withdrawal from any Multiemployer Plan under Section 4201 of ERISA.

(e)                                  Trace Texas has, at all times, complied, and currently complies, in all material respects with the applicable continuation requirements for its welfare benefit plans that are “group health plans” within the meaning of Section 5000(b)(i) of the Code, including (1) Section 4980B of the Code (as well as its predecessor provision, Section 162(k) of the Code) and Sections 601 through 608, inclusive, of ERISA, which provisions are hereinafter referred to collectively as “COBRA” and (2) any applicable state statutes mandating health insurance continuation coverage for employees.

28

(f)                                   The form of all Employee Plans is in compliance with the applicable terms of ERISA, the Code, and any other applicable Legal Requirements, and such plans have been operated in compliance with such laws and the written Employee Plan documents.  All required reports and descriptions of the Employee Plans (including Internal Revenue Service Form 5500 Annual Reports, Summary Annual Reports and Summary Plan Descriptions and Summaries of Material Modifications) have been (when required) timely filed with the IRS, the U.S. Department of Labor or other Governmental Body and distributed as required, and all notices required by ERISA or the Code or any other Legal Requirement with respect to the Employee Plans have been appropriately given.

(g)                                  There is no material pending or threatened Proceeding relating to any Employee Plan, nor is there any basis for any such Proceeding other than any pending routine determination filings, if any.  Neither Trace Texas nor any Fiduciary of an Employee Plan has engaged in a transaction with respect to any Employee Plan that, assuming the taxable period of such transaction expired as of the date hereof, could subject Trace Texas or Buyer to a Tax or penalty imposed by either Section 4975 of the Code or Section 502(l) of ERISA or a violation of Section 406 of ERISA.  The transactions contemplated hereby will not result in the potential assessment of a Tax or penalty under Section 4975 of the Code or Section 502(l) of ERISA nor result in a violation of Section 406 of ERISA.

(h)                                 Trace Texas has maintained workers’ compensation coverage as required by applicable state, provincial, or territorial law through purchase of insurance and not by self-insurance or otherwise except as disclosed to Buyer on Schedule 4.15(i).

(i)                                     Except as required by Legal Requirements or as set out in Schedule 4.15(j), the consummation of the transactions contemplated hereby will not accelerate the time of vesting or the time of payment, or increase the amount, of compensation due to any director, employee, officer, former employee or former officer of the Corporations.

(j)                                    Except for the continuation coverage requirements of COBRA, the Corporations have no obligations or potential liability for benefits to employees, former employees or their respective dependents following termination of employment or retirement under any of the Employee Plans that are Employee Welfare Benefit Plans.

(k)                                 None of the transactions contemplated hereby will result in an amendment, modification or termination of any of the Employee Plans. No written or oral representations have been made to any employee or former employee of the Corporations promising or guaranteeing any employer payment or funding for the continuation of medical, dental, life or disability coverage for any period of time beyond the end of the current plan year (except to the extent of coverage required under COBRA). No written or oral representations have been made by the Corporations to any employee or former employee of the Corporations concerning the employee benefits of the Buyer.

(l)                                     All Employee Plans of the Corporations other than the US Plans (as defined in paragraph (o) below) have been duly registered, where required, and are in good standing under all applicable legislation (foreign or domestic), including, without limiting the generality of the foregoing, the Tax Act, the Employment Pension Plans Act (Alberta), or similar legislation in

29

any other jurisdiction and all required employer contributions under any such plan(s) or policies have been made and no past service funding liabilities exist thereunder.

(m)                             Notwithstanding any provision to the contrary above, any representation that is made concerning an Employee Plan and its compliance with ERISA, the Code or any applicable Legal Requirements under U.S. law, or where the IRS, PBGC, ERISA, the Code or any applicable Legal Requirement under U.S. law is referred to in the context of such Employee Plan, such representation is hereby limited to Employee Plans that are sponsored, contributed to or maintained by the Corporations or any of their Subsidiaries in the United States on behalf of employees employed by such entities in the United States (“US Plans”) and no representation is made in such regard concerning any Employee Plans that are not US Plans.

Section 4.17                            Taxes.

(a)                                 Tax Returns Filed and Taxes Paid.  The Corporations have filed or caused to be filed on a timely basis all Tax Returns and all reports with respect to Taxes that are or were required to be filed pursuant to applicable Legal Requirements.  Trace Texas will file all Tax Returns and reports required to be filed in respect of its fiscal year ended December 31, 2004, on or before September 15, 2005.  All Tax Returns and reports filed by the Corporations are true, correct and complete (provided that this representation shall not be construed as a representation as to the existence, availability or value to the Buyer of any net operating loss, foreign tax credit or other tax attributes of the Corporations as of the Closing Time).  Each of the Sellers and the Corporations, as the case may be, has paid, or made provision for the payment of, all Taxes for which they are responsible that have or may have become due for all periods covered by the Tax Returns or otherwise, or pursuant to any assessment received by the Corporations, except such Taxes, if any, as are listed in Schedule 4.17 and are being contested in good faith and as to which adequate reserves (determined in accordance with US GAAP or Canadian GAAP, as applicable)

31

have been provided in the Interim Consolidated Balance Sheet and the Financial Statements.  Except as provided in Schedule 4.17, none of the Corporations are currently the beneficiary of any extension of time within which to file any Tax Return.  No claim has ever been made or is expected to be made by any Governmental Body in a jurisdiction where either Corporation does not file Tax Returns that it is or may be subject to taxation by that jurisdiction.  There are no Encumbrances on any of the assets of the Corporations that arose in connection with any failure to pay any Tax (other than Taxes not yet due and payable), and the Sellers have no Knowledge of any claims attributable to Taxes which, if adversely determined, would result in any such Encumbrance.

(b)                                 Delivery of Tax Returns and Information Regarding Audits and Potential Audits.  The Sellers have made available to Buyer copies of, and Schedule 4.17 contains a complete and accurate copy of, all federal, state, provincial, territorial, local, and foreign income Tax Returns of the Corporations (other than Tax Returns for sales and use taxes) filed since December 31, 2000.  Schedule 4.17 contains a complete and accurate list of all pending audits and Tax disputes.  Neither the Corporations nor any Seller expects any undisclosed deficiencies in payment of Tax to be asserted with respect to any such audit.  Any such deficiencies proposed as a result of such audits have been paid, reserved against, settled or are being contested in good faith.  The Sellers have made available to Buyer, copies of any examination reports, statements or deficiencies or similar items with respect to such audits in either Corporation’s possession.  Except as provided in Schedule 4.17, the Sellers have no Knowledge that any Governmental Body is likely to assess any additional taxes for any period for which Tax Returns have been filed.  Except as provided in Schedule 4.17, there is no dispute or claim concerning any Taxes of the Corporations either (i) claimed or raised by any Governmental Body in writing or (ii) as to which the Sellers have Knowledge.  Except as described in Schedule 4.17, neither Corporation has been given or been requested to give waivers or extensions (or is or would be subject to a waiver or extension given by any other Person) of any statute of limitations relating to the payment of Taxes of either Corporation or for which either Corporation may be liable.

(c)                                  Post-Closing Tax Liabilities.  The unpaid Taxes of the Corporations do not, as of the Closing Date, exceed the reserve for Tax Liability (rather than any reserve for deferred Taxes established to reflect timing differences between book and Tax income) set forth on the face of the Interim Consolidated Balance Sheet.  Except as disclosed in Schedule 4.17, since December 31, 2004, neither Corporation has received notice of any proposed tax assessment or deficiency against either Corporation.  Since the date of the Interim Consolidated Balance Sheet, the Corporations have not incurred any liability for Taxes arising from extraordinary gains or losses, as that term is used in Canadian GAAP.

(d)                                 Transactions Affecting Post-Closing Tax Years.  The Corporations will not be required to include any item of income in, or exclude any item of deduction from, taxable income for any taxable period (or portion thereof) ending after the Closing Date as a result of any (i) change in method of accounting for a taxable period ending on or prior to the Closing Date, (ii) ”closing agreement” as described in Code Section 7121 (or any corresponding provision or similar provision of federal, state, provincial, territorial, local or foreign income Tax law) executed on or prior to the Closing Date, (iii) installment sale or open transaction

32

disposition made on or prior to the Closing Date, or (iv) prepaid amount received on or prior to the Closing Date.

(e)                                  Specific Potential Tax Liabilities and Tax Situations.  Except as provided in Schedule 4.17:

(i)                                     Withholding.  All Taxes that the Corporations are or were required by Legal Requirements to withhold, deduct or collect prior to the Closing Date have been or will be duly withheld, deducted and collected and, to the extent required, will be paid to the proper Governmental Body or other Person.

(ii)                                  Tax Sharing or Similar Agreements.  There is no tax sharing agreement, tax allocation agreement, tax indemnity obligation or similar written or unwritten agreement or practice with respect to Taxes (including any advance pricing agreement, closing agreement or other arrangement relating to Taxes) that will require any payment by either Corporation after the Closing.

(iii)                               Consolidated Group.  Neither Corporation (i) has been a member of an Affiliated Group (or any similar group defined under a similar provision of federal, state, provincial, territorial, local or foreign law) and (ii) has no liability for Taxes of any person (other than the Corporations) under §1.1502-6 of the Treasury Regulations (or any similar provision of state, local or foreign law), as a transferee or successor by contract or otherwise.

(iv)                              Listed Transactions.  In the past six years, neither Corporation has ever participated in a transaction that has been specifically identified by the IRS as a “listed” transaction for purposes of §1.6011-4(b) of the Treasury Regulations and has not disclosed any transactions to the IRS under any penalty amnesty program.

(v)                                 Golden Parachute Agreements.  Neither Corporation is a party to any agreement, contract or plan that as a result of the consummation of the transactions contemplated hereby could result, separately or in the aggregate, in the payment of (i) any “excess parachute payment” within the meaning of Code Section 280G (or any corresponding provision of federal, state, provincial, territorial, local or foreign Tax law) and (ii) any amount that will not be fully deductible as a result of Code Section 162(m) (or any corresponding provision of state, local or foreign Tax law).

(vi)                              Arrangement Constituting a Partnership.  Neither Corporation is subject to any joint venture, partnership or other arrangement or contract that is treated as a partnership for federal or applicable state income tax purposes or for any other Tax purposes.

(vii)                           Tax Attributes.  Subject to the general qualification made in Section 4.17(a) that no representation will be made as the actual value of such amounts, Schedule 4.17(f)(vii) sets forth the estimated amount of any net operating loss, net capital loss, unused investment, foreign tax or other credit, or excess charitable contribution allocable to either Corporation as of December 31, 2004.

33

(f)                                   Since December 31, 2004, the Corporations have not:

(i)                                     made any election under Section 85 of the Tax Act with respect to the acquisition or disposition of any property;

(ii)                                  made any election under Section 83 or 196 of the Tax Act; or

(b)                                 Each such Section 116 Certificate shall fix (or otherwise be based on an amount equal to) a certificate limit that is not less than the price payable to the applicable Non-Resident Seller for the Non-Resident Seller’s Trace Common Stock (such price for the Non-Resident Seller’s Trace Common Stock being referred to herein as the “NRV Purchase Price” and, in the case of the partial payment with Geokinetics Shares as referred to in Section 2.2(a), shall have an amount added to the cash portion of the Purchase Price payable to them equal to the number of Geokinetics Shares multiplied by the 10 day weighted average trading price of the shares of the common stock of the Buyer before the Closing Date (converted to Canadian dollars using the Exchange Rate).

(c)                                  If a Non-Resident Seller does not deliver or cause to be delivered a Section 116 Certificate containing a certificate limit as required by Section 6.7(b) to the Buyer at or prior to the Closing Date, the Non-Resident Seller acknowledges that the Buyer shall be entitled to deduct an amount from the NRV Purchase Price payable by the Buyer to the Non-Resident Seller on the Closing Date equal to 25% of such NRV Purchase Price, provided that a corresponding amount of any such deduction (the “Withheld Amount”) shall be paid in cash and deposited by the Buyer to the Sellers’ Solicitors on the Closing Date, on the condition that such amount shall be held by the Sellers’ Solicitors in trust pending the delivery to the Buyer of a Section 116 Certificate with a certificate limit that is not less the full amount of the NRV Purchase Price payable to the Non-Resident Seller, all in accordance with the following terms and conditions:

(i)                                     the deposit of the Withheld Amount with the Sellers’ Solicitors by the Buyer on the Closing Date shall satisfy the Buyer’s payment obligation in respect of the corresponding portion of the NRV Purchase Price payable to the Non-Resident Seller;

49

Sellers’ Solicitors for the Non-Resident Seller (including any interest earned on the funds held in trust less any Canadian withholding tax on such interest) shall be paid to the Non-Resident Seller;

(iv)                              if a Section 116 Certificate has not been provided to the Buyer as set out above on or before the 30^th day after the end of the month in which the Closing Date occurs, the Sellers’ Solicitors shall remit the full amount it continues to hold in trust for the applicable Non-Resident Seller at that date (less any interest earned in respect of such funds) to the Receiver General for Canada in satisfaction of the Buyer’s withholding tax liability in respect of the purchase of the Non-Resident Seller’s Trace Common Stock pursuant to subsection 116(5) of the Tax Act, unless the Non-Resident Seller provides evidence satisfactory to the Buyer (acting reasonably) that the Canada Revenue Agency has instructed that the funds not be remitted at such time, in which case the funds held by the Escrow Agent shall continue to be held in trust;

(v)                                 in the event that subparagraph (iv) applies to defer the time at which amounts would otherwise be required to be remitted to the Receiver General for Canada under that paragraph, the provisions of this paragraph (c) shall continue to apply to any such withheld funds as if the reference to the date that such amounts are required to be remitted to the Receiver General for Canada were instead a reference to the new date set by the Canada Revenue Agency as the date for the remittance or the date remittance is otherwise required by law;

(vi)                              if the aggregate certificate limit in the Section 116 Certificate provided to the Buyer by the Non-Resident Seller is less than the NRV Purchase Price payable to the Non-Resident Seller, the Sellers’ Solicitors shall remit 25% of the difference between such excess NRV Purchase Price amount and the certificate limit shown in the Section 116 Certificate to the Receiver General for Canada in satisfaction of the Buyer’s withholding tax liability in respect of the purchase of the Non-Resident Seller’s Trace Common Stock pursuant to subsection 116(5) of the Tax Act, and any excess funds held by the Sellers’ Solicitors following such remittance (including any interest earned on the funds held in trust less any Canadian withholding tax on such interest) shall be paid to the Non-Resident Seller;

(vii)                           the funds held by the Sellers’ Solicitors for the Non-Resident Seller shall be invested in an interest bearing account, with any such interest (less any applicable Canadian withholding tax) to accrue for the benefit of the Non-Resident Seller; and

(viii)                        if requested by the Non-Resident Seller, the Sellers’ Solicitors will be entitled to pay all or any portion of the funds that it holds in trust for the Non-Resident Seller directly to the Receiver General for Canada against delivery by the Canada Revenue Agency of a Section 116 Certificate.

Section 8.5                                   Indemnification Procedure.

The following procedure shall apply to a claim for indemnity described in this Article VIII:

(a)                                 For purposes of this Section, the term “Indemnifying Party” when used in connection with a Claim shall mean the Person having an obligation to indemnify another Person with respect to such Claim pursuant to this Agreement and the term “Indemnified Party” when used in connection with a particular Claim shall mean the Person having the right to be indemnified with respect to such Claim by the Indemnifying Party pursuant to this Agreement;

(b)                                 To make claim for indemnification, an Indemnified Party shall notify the Indemnifying Party of its Claim, including the specific details of and specific basis under this Agreement for its Claim (the “Claim Notice”).  In the event that the claim for indemnification is based upon a Claim by a third party against the Indemnified Party (a “Third Party Claim”), the Indemnified Party shall provide its Claim Notice promptly after the Indemnified Party has actual knowledge of the Third Party Claim and shall enclose a copy of all papers (if any) served with respect to the Third Party Claim; provided that the failure of any Indemnified Party to give notice of a Third Party Claim as provided herein shall not relieve the Indemnifying Party of its obligations under this Agreement except to the extent such failure results in insufficient time being available to permit the Indemnifying Party to effectively defend against the Third Party Claim or otherwise materially prejudices the Indemnifying Party’s ability to defend against the Third Party Claim or increases the amount of liability or cost of defense.  In the event that the claim for indemnification is based upon an inaccuracy or breach of a representation, warranty, covenant or agreement, the Claim Notice shall specify the representation, warranty, covenant or agreement which was inaccurate or breached;

(c)                                  The Indemnifying Party shall have the right, by notice to the Indemnified Party given not later than 60 days after receipt of the Claim Notice, to assume the control of the compromise, settlement and defense of the Third Party Claim, provided that such assumption shall, by its terms, be without cost to the Indemnified Party.  The Indemnified Party is authorized, prior to and during such 60-day period, to file any motion, answer or other pleading that it shall deem necessary or appropriate to protect its interests or those of the Indemnifying Party and that is not prejudicial to the Indemnifying Party;

(d)                                 Upon the assumption of control of any Third Party Claim by the Indemnifying Party on the basis provided herein, the Indemnifying Party shall diligently proceed with the defense, compromise or settlement of the Third Party Claim, including, the employment of counsel satisfactory to the Indemnifying Party and, in connection therewith, the Indemnified Party shall: (i) cooperate fully and to make available to the Indemnifying Party all pertinent information, documents and witnesses under the Indemnified Party’s control; and (ii) make such assignments and take such other steps as on the advice of counsel for the Indemnifying Party are reasonably necessary to enable the Indemnifying Party to conduct such defense;

(e)                                  Notwithstanding any other provision contained herein, the Indemnified Party, at its sole expense, shall have the right to participate in the negotiation, settlement and defense of any Third Party Claim and the Indemnifying Party shall not negotiate, settle, compromise or pay

any Third Party Claim without the prior written consent of the Indemnified Party; such consent not to be unreasonably withheld or delayed;

(f)                                   Should the Indemnifying Party fail to give notice to the Indemnified Party in accordance with subsection (d) above, the Indemnified Party shall diligently proceed with the defense, compromise or settlement of the Third Party Claim, and, in connection therewith, the Indemnifying Party shall, at its sole expense, cooperate fully to make available to the Indemnified Party all pertinent information and witnesses under the Indemnifying Party’s control and (ii) make such assignments and take such other steps as on the advice of counsel for the Indemnified Party are reasonably necessary to conduct such defense.

Section 10.8                            Governing Law.

This Agreement shall be governed by and construed in accordance with the domestic laws of the State of Texas without giving effect to any choice or conflict of law provision or rule (whether of the State of Texas or any other jurisdiction) that would cause the application of the laws of any jurisdiction other than the State of Texas.

64

Section 10.9                            Amendments and Waivers.

No amendment of any provision of this Agreement shall be valid unless the same shall be in writing and signed by the Buyer and the Sellers.  No waiver by any Party of any default, misrepresentation, or Breach of warranty or covenant hereunder, whether intentional or not, shall be deemed to extend to any, prior or subsequent default, misrepresentation, or Breach of warranty or covenant hereunder or affect in any way any rights arising by virtue of any prior or subsequent such occurrence.

Section 10.10                     Severability.

Any term or provision of this Agreement that is invalid or unenforceable in any situation in any jurisdiction shall not affect the validity or enforceability of the remaining terms and provisions hereof or the validity or enforceability, of the offending term or provision in any other situation or in any other jurisdiction.

Section 10.11                     Expenses.

Except as otherwise provided herein, each of the Parties will bear his or its own costs and expenses (including legal fees and expenses) incurred in connection with this Agreement and the transactions contemplated hereby.  The Parties acknowledge that Trace has borne all of the Seller’s costs and expenses (including legal fees) in connection with this Agreement and any of the transactions contemplated hereby and that Trace (and no other Party) shall pay the Transaction Costs, Option Costs and I/O Option Costs (if any) at Closing.

Section 10.12                     Construction.

The Parties have participated jointly in the negotiation and drafting of this Agreement.  In the event an ambiguity or question of intent or interpretation arises, this Agreement shall be construed as if drafted jointly by the Parties and no presumption or burden of proof shall arise favoring or disfavoring any Party by virtue of the authorship of any of the provisions of this Agreement.  Any reference to any federal, state, local, or foreign statute or law shall be deemed also to refer to all rules and regulations promulgated thereunder, unless the context requires otherwise.  The word “including” shall mean including without limitation.  The Parties intend that each representation, warranty, and covenant contained herein shall have independent significance.  If any Party 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 the Party has not Breached shall not detract from or mitigate the fact that the Party is in Breach of the first representation, warranty, or covenant.  Matters disclosed by the Sellers in any exhibit or schedule to this Agreement shall be deemed disclosed as to all portions of this Agreement and shall qualify all such portions of the Agreement, without being restricted to the express provisions that they are identified as excepting.  Any waiver or consent may be given subject to satisfaction of conditions stated therein and any waiver or consent shall be effective only in the specific instance and for the specific purpose for which given.

Each of the Parties submits to the jurisdiction of any state or federal court sitting in Harris County, Texas, in any action or proceeding arising out of or relating to this Agreement and agrees that all claims in respect of the action or proceeding may be heard and determined in any such court.  Each of the Parties waives any defense of inconvenient forum to the maintenance of any action or proceeding so brought and waives any bond, surety, or other security that might be required of any other Party with respect thereto.  Any Party may make service on any other Party by sending or delivering a copy of the process  to the Party to be served at the address and in the manner provided for the giving of notices in Section 10.7 above.  Nothing in this Section 10.14, however, shall affect the right of any Party to bring any action or proceeding arising out of or relating to this Agreement in any other court or to serve legal process in any other manner permitted by law or at equity.  Each Party agrees that a final judgment in any action or proceeding so brought shall be conclusive and may be enforced by suit on the judgment or in any other manner provided by law or at equity.
