     2.1 Agreement to Purchase and Sell; Non-assumed Liabilities.

     (a) Agreement to Purchase and Sell. Upon the terms and subject to the conditions set forth in this Agreement, at the closing of the transactions contemplated by this Agreement (the “Closing”), DFI and Newpark Texas shall sell, transfer, convey and assign to Purchaser, and Purchaser shall purchase and acquire from DFI and Newpark Texas, all of DFI’s and Newpark Texas’ respective rights, title and interest in and to the Acquired Interests, free and clear of all Liens other than Permitted Liens (the “Sale”).

     (b) Non-Assumption of Liabilities. Neither Purchaser nor any of its Affiliates or Subsidiaries (other than the Transferred Entities following the Closing, but subject in all respects to Purchaser’s and its Affiliates’ (including the Transferred Entities’) right to indemnification pursuant to Section 10.2(c) for the Non-assumed Liabilities) shall, by the execution and performance of this Agreement, by operation of law or otherwise, assume, become responsible for or incur any liability or obligation of any nature of the Transferred Entities, whether legal or equitable, matured or contingent, known or unknown, foreseen or unforeseen, ordinary or extraordinary, patent or latent, asserted prior to, at or after the date of this Agreement, relating to the following:

     (i) any severance pay obligation of any of the Transferred Entities or of Newpark Texas, DFI, Newpark or any of its other Affiliates or Subsidiaries with respect to any Former Employee;

     (ii) any Benefit Plan (other than (A) the Change of Control Agreements listed in Section 3.16(h)(ii) of the Newpark Disclosure Schedule between NESI and the Transferred Employees listed therein, and (B) the liabilities and obligations of any Transferred Entity under any Benefit Plan to the extent of any amounts with respect thereto are recorded as a liability in the calculation of the Estimated Net Working Capital, as adjusted by the Closing Date Net Working Capital, for which Purchaser shall be responsible post-Closing), including, without limitation, the Newpark Group Health Plan, and any other employee benefit plan (within the meaning of Section 3(3) of ERISA) or any other fringe benefit program maintained or sponsored by Newpark or any of its Subsidiaries or Affiliates or to which Newpark or any of its Subsidiaries or Affiliates contributes or any contributions, benefits or liabilities therefor or any liability for the withdrawal or partial withdrawal from or termination of any such plan or program by Newpark or any of its Subsidiaries or Affiliates;

     (iv) any closure, post-closure, monitoring, testing, analyzing, clean-up or remediation obligations relating to the site or facility known as the ▇▇▇▇▇▇▇▇ Landfarm near Eunice, Louisiana; and

Notwithstanding the foregoing, Capital Leases of the Transferred Entities shall not be considered a Non-assumed Liability.

Each and all of the foregoing are hereinafter referred to as the “Non-assumed Liabilities.”

     (c) Transferred Entities’ Liabilities. The provisions of Section 2.1(b) above shall not in any manner adversely affect, diminish or otherwise relieve the Transferred Entities from their respective obligations to pay, discharge, perform or otherwise satisfy, as the case may be, any and all liabilities, commitments or obligations of the Transferred Entities, subject in all respects to Purchaser’s right to seek indemnification with respect thereto under Article X.

     2.2 Consideration.

     (a) In consideration for the Acquired Interests, Purchaser shall pay an aggregate amount equal to the sum of (i) $81,500,000, subject to the adjustments in Section 2.4(a) and Section 5.14(c) (the “Initial Closing Consideration”), plus (ii) if earned, the Earn-Out Consideration (the foregoing aggregate amount, as adjusted pursuant to the terms of this Agreement, being referred to as the “Purchase Price”), payable as described below. The Earn-Out Consideration, if earned, shall be calculated and paid in accordance with Section 2.5.

     (b) Newpark agrees that the sum of $6,112,500 (the “Holdback Funds”) otherwise payable to Newpark as part of the Purchase Price at Closing shall be delivered by Purchaser to an escrow agent mutually agreed upon by Newpark and Purchaser (the “Escrow Agent”) pursuant to an escrow agreement mutually acceptable to Newpark, Purchaser and the Escrow Agent (the “Escrow Agreement”) to be held by the Escrow Agent in an interest bearing account (the “Escrow Account”) as required by the terms of the Escrow Agreement and this provision. Newpark shall be entitled to all interest earned on the Escrow Account except as specifically provided in this Section 2.2(b). The Holdback Funds shall be applied towards any claims made by a Purchaser Indemnified Party pursuant to Article X below and in accordance with the terms of the Escrow Agreement. The Purchaser Indemnified Parties shall first seek reimbursement for any Losses for which they are entitled to receive indemnification under this Agreement out of the funds deposited in the Escrow Account, pursuant to the terms of the Escrow Agreement, until such funds are exhausted or released from the Escrow Account. On the first anniversary of the Closing, the Holdback Amount shall be reduced to an amount equal to the lesser of: (i) $3,056,250, or (ii) the remaining funds held in the Escrow Account, and any amounts in excess of $3,056,250 shall be released to Newpark, unless prior to that date Purchaser advises the Escrow Agent and Newpark in writing that any claim for indemnification (each, a “Claim”) by any Purchaser Indemnified Party is pending. Any such notice shall specify the total amount of the pending Claim(s). If such notice is timely received by the Escrow Agent, the Escrow Agent

shall release only that part of the Escrow Account that is eligible to be released pursuant to the preceding sentence that exceeds the total amount of any Claim(s) received, with the remaining funds to be held in the Escrow Account until such Claim(s) are resolved. On the second anniversary of the Closing, the remaining funds held in the Escrow Account shall be released to Newpark, unless any Claim(s) have been made and are not resolved, in which event the Escrow Agent shall release only that part, if any, of the Escrow Account that exceeds the total amount of unresolved Claim(s), with the remaining funds relevant to the unresolved Claim(s) to be held in escrow until such Claim(s) are resolved.

     2.3 Closing.

     (a) The Closing shall take place at the offices of ▇▇▇▇▇▇▇ ▇▇▇▇▇ LLP, 10001 ▇▇▇▇▇▇▇▇ ▇▇▇▇▇▇ ▇▇▇▇▇, ▇▇▇▇▇ ▇▇▇, ▇▇▇ ▇▇▇▇▇▇▇▇▇, ▇▇▇▇▇ ▇▇▇▇▇ at 10:00 a.m., Houston, Texas time, on the date (the “Closing Date”) that is one Business Day following the satisfaction or waiver of the conditions set forth in Article VIII (other than those conditions that by their nature are to be satisfied or waived at the Closing, but subject to the satisfaction or waiver of those conditions) or at such other place, time or date as may be mutually agreed upon in writing by Newpark and Purchaser. Notwithstanding the foregoing, the parties hereto intend that such Closing shall be deemed to be effective, and the transactions contemplated by this Agreement shall be deemed to occur simultaneously, at 11:59 p.m., Central Daylight Time, on the Closing Date (the “Effective Time”).

     (b) At the Closing:

     (i) DFI and Newpark Texas, as applicable, shall deliver or cause to be delivered to or for the benefit of the Purchaser, in the case of documents, duly executed by each applicable party, the following:

     (A) certificates evidencing the Acquired Interests to the extent that such Acquired Interests are in certificate form, duly endorsed in blank or with stock powers duly executed in proper form for transfer, and with any required stock transfer stamps affixed thereto;

     (B) to the extent that the Acquired Interests are not in certificate form, such documents evidencing the transfer, assignment, conveyance and sale of the Acquired Interests by DFI and Newpark Texas to Purchaser, as Purchaser may reasonably require;

     (C) resignation letters, effective as of the Effective Time, of those managers, directors or officers of the Transferred Entities as Purchaser may request in writing no less than five (5) Business Days prior to the Closing Date;

     (D) all minute books, formation, organizational, governance and similar “corporate” documents and records and all other files, documents, data, information, papers, personnel and employment records and other records of the Transferred Entities, relating to the conduct of the Business and the ownership, use and possession of the assets of the Transferred Entities in connection therewith, in the possession of Newpark or any of its Affiliates, other than (A) any

books and records that Newpark or any of its Affiliates is required by Law to retain the originals of, in which case copies thereof shall be made available to Purchaser; and (B) personnel and employment records for employees and Former Employees of Newpark or any of its Affiliates who are not Transferred Employees; provided, that Newpark and its Subsidiaries shall have the right to retain a copy of all such books and records to the extent reasonably necessary for, and for use in connection with, Tax, regulatory, litigation or other legitimate, non-competitive purposes;

     (E) an acknowledgement from DFI and Newpark Texas of the receipt of the Initial Closing Consideration, less the Holdback Funds;

     (F) evidence, reasonably satisfactory to Purchaser, of the release of the Liens and releases of liability of the Transferred Entities with respect to the payment of the funded Indebtedness as required pursuant to Section 8.2(d);

     (G) the certificate required by Section 8.2(c) hereof;

     (H) a legal opinion of counsel to Newpark, DFI and Newpark Texas, dated as of the Closing, addressed to Purchaser in the form and substance reasonably satisfactory to Purchaser, which shall expressly entitle Purchaser’s lenders to rely thereon;

     (I) the Escrow Agreement;

     (J) a resolution or other document reasonably satisfactory to Purchaser evidencing the withdrawal as of the Effective Time of NESI, and any of the other Transferred Entities that are “Adopting Employers” as defined in the Newpark Resources, Inc. Savings and Incentive Plan, from said plan; and

     (K) such other documents and certificates required to be delivered by DFI or Newpark Texas pursuant to the terms of this Agreement.

     (ii) The Purchaser shall deliver or cause to be delivered to or for the benefit of DFI or Newpark Texas, as applicable, in the case of documents, duly executed, the following:

     (A) the Initial Closing Consideration, less the amount of the Holdback Funds, in cash by wire transfer of immediately available funds into an account or accounts designated by Newpark not less than two (2) Business Days prior to the Closing;

     (B) the Holdback Funds in cash by wire transfer of immediately available funds to the Escrow Agent;

     (C) the certificate required by Section 8.3(c) hereof;

     (D) the Escrow Agreement; and

     (E) such other documents and certificates required to be delivered by the Purchaser pursuant to the terms of this Agreement.

     2.4 Working Capital Price Adjustment.

     (a) (i) For the purpose of determining the Initial Closing Consideration, at least five (5) Business Days prior to the Closing Date, Newpark shall cause to be prepared and delivered to Purchaser a statement (the “Estimated Closing Statement”) setting forth a good faith estimate of the Net Working Capital (the “Estimated Net Working Capital”) and the components and calculation thereof, as of the Effective Time, determined in accordance with this Section 2.4. The Estimated Closing Statement shall be subject to the review and agreement of Purchaser, and Newpark and the Purchaser shall cooperate and negotiate in good faith to resolve any dispute regarding the Estimated Closing Statement prior to the Closing; provided, however, that if any item of dispute regarding the Estimated Closing Statement and the calculation of the Estimated Net Working Capital is not resolved by agreement in writing between Newpark and the Purchaser by the second Business Day prior to the Closing Date, then Newpark’s estimate of such disputed item, together with the resolved disputed items, shall be deemed final solely for purposes of determining the Estimated Net Working Capital.

     (ii) To the extent the Estimated Net Working Capital is greater than $5,250,000 (such difference being herein referred to as the “Estimated Net Working Capital Excess Amount”), the Initial Closing Consideration shall be increased by the amount of the Estimated Net Working Capital Excess Amount as provided in Section 2.2. To the extent the Estimated Net Working Capital is less than $5,250,000 (such difference being herein referred to as the “Estimated Net Working Capital Deficiency Amount”), the Initial Closing Consideration shall be reduced by the amount of the Estimated Net Working Capital Deficiency Amount as provided in Section 2.2.

     (b) Within sixty (60) calendar days of the Closing Date, the Purchaser shall cause to be prepared and delivered to Newpark a statement (the “Final Closing Statement”) setting forth the actual Net Working Capital as of the Effective Time (the “Closing Date Net Working Capital”), the components and calculation thereof, and the difference, if any, between the Estimated Net Working Capital and the Closing Date Net Working Capital (the amount of such difference being referred to as the “Final Working Capital Adjustment”). If the Final Closing Statement reflects a difference between the Estimated Net Working Capital and the amount of the Closing Date Net Working Capital, Newpark shall have thirty (30) calendar days following the receipt of the Final Closing Statement to review the components and calculation of the Closing Date Net Working Capital. The failure of Newpark to object to the Final Closing Statement within such thirty (30) calendar day period shall be deemed to be an acceptance by Newpark of the Final Working Capital Adjustment. If Purchaser and Newpark agree on all matters in the Final Closing Statement and the calculation of the Closing Date Net Working Capital, or if Newpark otherwise fails to timely object to such matters, then:

     (i) if the Closing Date Net Working Capital is greater than the Estimated Net Working Capital, the Final Working Capital Adjustment shall be paid by Purchaser to Newpark within three (3) Business Days of Newpark’s acceptance, or deemed acceptance, of the Final Working Capital Adjustment, with such funds paid via wire transfer of immediately available funds to the account designated by Newpark; and

acceptance, of the Final Working Capital Adjustment, with such funds paid via wire transfer of immediately available funds to the account designated by Newpark; and

     (ii) if the Closing Date Net Working Capital is less than the Estimated Net Working Capital, the Final Working Capital Adjustment shall be deducted from and reduce the Purchase Price and Newpark shall pay to Purchaser, within three (3) Business Days of Newpark’s acceptance, or deemed acceptance, of the Final Working Capital Adjustment, an amount equal to the Final Working Capital Adjustment, with such amount paid via wire transfer of immediately available funds to the account designated by Purchaser.

If Newpark and Purchaser are unable to agree on any component or the calculation of the Closing Date Net Working Capital and the Final Working Capital Adjustment, such dispute shall be resolved by a nationally recognized accounting firm reasonably acceptable to Newpark and Purchaser who shall not be Ernst & Young, L.L.P. or Purchaser’s accounting firm (the “Accounting Arbitrator”), whose determination shall be final and binding on Purchaser and Newpark, and any required payments by Purchaser to Newpark, on the one hand, or by Newpark to the Purchaser, on the other hand, shall be made within three (3) Business Days of the final resolution of such dispute. All fees and expenses of the Accounting Arbitrator shall be paid by the party whose proposed Closing Date Net Working Capital is farthest from the final Closing Date Net Working Capital as determined by such Accounting Arbitrator. Any dispute as to which party’s proposed Closing Date Net Working Capital is closest to the final Closing Date Net Working Capital shall be resolved by the Accounting Arbitrator and shall be specified in the final report prepared by such Accounting Arbitrator. Each of Purchaser and Newpark shall pay their respective advisor’s fees, charges and expenses incurred by such Person in connection with the dispute.

     (c) For purposes of this Agreement, “Net Working Capital” shall (i) be calculated as of the Effective Time on an aggregate basis among the Transferred Entities and (ii) mean the amount equal to the Current Assets minus Current Liabilities. “Current Assets” shall mean, subject to the adjustments set forth below, the current assets of the Transferred Entities as of the Effective Time comprised of accounts receivable, whether billed or unbilled (net of allowances for doubtful accounts); costs and estimated earnings in excess of ▇▇▇▇▇▇▇▇ on uncompleted contracts; the current portion of any notes or other receivables; inventories; and prepaid expenses. “Current Liabilities” shall mean, subject to the adjustments set forth herein, the current liabilities of the Transferred Entities as of the Effective Time comprised of accounts payable; accrued liabilities; the current portion of any Capital Leases; ▇▇▇▇▇▇▇▇ in excess of costs and estimated earnings on uncompleted contracts; and, payroll, accrued incentive compensation and bonuses, accrued vacation benefits and related taxes and withholdings payable. Subject to the adjustments set forth below, Current Assets and Current Liabilities shall be computed in accordance with GAAP on a basis consistent with the December 31, 2006 combined balance sheet of NESI. Notwithstanding the foregoing, for purposes of calculating the Net Working Capital, the Current Assets and the Current Liabilities shall not include:

     (i) to the extent not incurred in the ordinary course of business, intercompany receivables and payables between or among any of the Transferred Entities, Newpark and its other Affiliates;

     (ii) any bank or funded Indebtedness including, without limitation, any short-term debt and the current portion of any long-term debt; and

     (iii) any liability for income taxes payable by any of the Transferred Entities.

     (d) The provisions of this Section 2.4 shall not be subject to the provisions of Article X hereof or any limitations of liability set forth therein.

     2.5 Earn-Out Consideration. Subject to the terms and conditions of this Section 2.5, DFI and Newpark Texas shall be entitled to receive the following additional consideration (the “Earn-Out Consideration”), if earned.

     (a) Payment of Earn-Out Consideration. For each of the first five Measurement Periods, in the event the Post-Closing EBITDA exceeds the Baseline EBITDA for an individual Measurement Period, Purchaser and/or Trinity will pay to DFI and Newpark Texas additional aggregate consideration (a “Measurement Period Earn-Out Payment”) of Fifty Cents ($0.50) for each One Dollar ($1.00) that the Post-Closing EBITDA for any individual Measurement Period exceeds the Baseline EBITDA; provided, however, that in no event shall the total Earn-Out Consideration payable hereunder exceed $8,000,000, subject to adjustment as provided in Section 5.14(c) (as adjusted, the “Maximum Earn-Out Amount”). If the Closing occurs during 2008, for purposes of calculating the Measurement Period Earn-Out Payment for the initial Measurement Period, the Baseline EBITDA shall be proportionately reduced to an amount equal to the Baseline EBITDA multiplied by a fraction, the numerator of which is the number of full calendar months in 2008 following the Closing and the denominator of which is twelve (12).

     (b) Post-Closing EBITDA. For purposes of this Agreement, “Post-Closing EBITDA” means the combined net income of Trinity, ▇▇▇▇ Bluff Property, L.P. (“MBP”) and Purchaser for the relevant Measurement Period, calculated in accordance with GAAP consistently applied, plus interest expenses, federal, state and local taxes based on income, depreciation and amortization and subject to the adjustments as provided in this Section 2.5(b). In calculating Post-Closing EBITDA, the parties agree to the following adjustments: (i) all legal, accounting, broker and advisory fees and expenses directly related to the acquisition of the Transferred Entities and Escrow Agreement expenses shall be disregarded; (ii) management fees payable to Affiliates of Trinity and/or Purchaser shall be disregarded; (iii) asset impairments and similar non-cash charges shall be disregarded; and (iv) any extraordinary, non-recurring or unusual gains, losses or expenses on sales of assets or businesses (including sales other than in the ordinary course of business) shall be disregarded.

     (c) Baseline EBITDA. For purposes of this Agreement, the “Baseline EBITDA” means an amount equal to (i) the combined net income, calculated in accordance with GAAP consistently applied, plus interest expenses, federal, state and local taxes based on income, depreciation and amortization and subject to the adjustments as provided in this Section 2.5(c), of (A) Trinity and MBP, on a combined basis, and (B) the Transferred Entities, on a combined basis, for the twelve (12) calendar month period ending with the month immediately preceding the month in which the Closing occurs, less (ii) the sum of $500,000; provided, however, that the Baseline EBITDA, for purposes of calculating the Measurement Period Earn-Out Payment for any Measurement Period, shall not be less than $17,694,000. (For the avoidance of doubt, if the

Closing occurs in December 2007, the Baseline EBITDA shall be determined for the period of December 1, 2006 through November 30, 2007.) In calculating Baseline EBITDA, the parties agree to the following adjustments: (i) all legal, accounting, broker and advisory fees and expenses directly related to the acquisition of the Transferred Entities and Escrow Agreement expenses shall be disregarded; (ii) general administrative and overhead expenses shall be disregarded with respect to the Transferred Entities, except that direct costs of Newpark and its Affiliates related to the Business prior to the Closing shall be considered for purposes of calculating Baseline EBITDA; (iii) management fees payable to Affiliates of Trinity and/or MBP shall be disregarded with respect to Trinity and MBP; (iv) asset impairments and similar non-cash charges shall be disregarded; and (v) any extraordinary, non-recurring or unusual gains, losses or expenses on sales of assets or businesses (including sales other than in the ordinary course of business) shall be disregarded. Within five (5) Business Days of the execution of this agreement the parties shall jointly prepare an estimate of the Baseline EBITDA, calculated on a pro forma basis in accordance with the foregoing provisions as if the Closing occurred in December 2007 (the “Estimated Baseline EBITDA”). Not less than five (5) Business Days prior to the Closing Date, Newpark and Purchaser shall deliver to the other a statement setting forth such party’s respective input into the calculation of the actual Baseline EBITDA. The actual Baseline EBITDA shall be calculated in a manner consistent with the calculation of the Estimated Baseline EBITDA. Newpark and Purchaser shall attempt, in good faith, to mutually agree upon the actual Baseline EBITDA on or before the Closing Date. Each such party shall provide to the other access to all relevant books, records and personnel as may be reasonably requested for purposes of determining the final Baseline EBITDA. If Newpark and Purchaser are unable to mutually agree upon the final Baseline EBITDA prior to the Closing Date, such dispute shall be resolved promptly following the Closing by an Accounting Arbitrator, who shall be selected in the same process described in Section 2.4(b), whose decision shall be final and binding on the parties hereto. All fees and expenses of the Accounting Arbitrator shall be paid by the party whose proposed Baseline EBITDA is farthest from the final Baseline EBITDA as determined by the Accounting Arbitrator. Any dispute as to which party’s proposed Baseline EBITDA is closest to the final Baseline EBITDA shall be resolved by the Accounting Arbitrator and shall be specified in the final report prepared by such Accounting Arbitrator. Each of Newpark and Purchaser shall pay their respective advisor’s fees, charges and expenses incurred by such Person in connection with the dispute. At the Closing, unless a dispute exists with respect to the calculation of the actual Baseline EBITDA (which shall be resolved by the Accounting Arbitrator post-Closing), the parties shall execute a written acknowledgment of the actual Baseline EBITDA as finally determined in accordance with this Section 2.5(c).

     (d) Procedures for Calculating Post-Closing EBITDA and Measurement Period Earn-Out Payments.

     (i) Within one hundred twenty (120) days following the end of each of the first five (5) Measurement Periods, Purchaser will deliver to Newpark a statement in writing setting forth Purchaser’s determination of the Post-Closing EBITDA for such Measurement Period, and a calculation of the resulting Measurement Period Earn-Out Payment to be made by Purchaser and/or Trinity for such Measurement Period (each such statement, a “Trinity Earn-Out Statement”). Trinity or Purchaser shall provide to Newpark prior to March 1 of each calendar year following each of the first five (5) Measurement Periods a preliminary non-binding estimate of the Post-Closing EBITDA

and Measurement Period Earn-Out Payment relating to the immediately preceding Measurement Period. During each of the first five (5) Measurement Periods, upon reasonable request by Newpark, Trinity or Purchaser shall provide quarterly estimates of the Post-Closing EBITDA for any such Measurement Period for purposes of Newpark’s financial reporting obligations.

     (ii) Newpark shall have a period of up to thirty (30) days following its receipt of a Trinity Earn-Out Statement to review Purchaser’s calculation of Post-Closing EBITDA and the applicable Measurement Period Earn-Out Payment. In connection with the review of the Trinity Earn-Out Statement, Purchaser shall, and shall cause Trinity and MBP to, provide to Newpark reasonable access to all relevant books and records and personnel of Purchaser, Trinity, MPB and their Affiliates. If, as a result of such review, Newpark disagrees with the calculation of Post-Closing EBITDA and the respective Measurement Period Earn-Out Payment, Newpark shall deliver to Purchaser a written notice of disagreement (an “Earn-Out Dispute Notice”) prior to the expiration of such thirty (30) day review setting forth the basis of such dispute. Upon Purchaser’s receipt of an Earn-Out Dispute Notice, Purchaser and Newpark agree to negotiate in good faith to resolve the dispute set forth in the Earn-Out Dispute Notice. If Purchaser and Newpark have not resolved the dispute within thirty (30) days following Purchaser’s receipt of the Earn-Out Dispute Notice (or such longer period of time as Purchaser and Newpark may mutually agree), then Newpark and Purchaser agree to finally resolve such dispute in accordance with Section 2.5(d)(iii) below.

     (iii) If Purchaser and Newpark cannot reach agreement as described in Section 2.5(d)(ii) above, then the dispute shall be promptly referred to an Accounting Arbitrator, who shall be selected in the same process described in Section 2.4(b), for binding resolution. The Accounting Arbitrator shall determine the Post-Closing EBITDA for the respective Measurement Period and the applicable Measurement Period Earn-Out Payment in accordance with the provisions of this Agreement as promptly as may be reasonably practicable and shall endeavor to complete such process within a period of no more than sixty (60) days following appointment of the Accounting Arbitrator. A determination of the Accounting Arbitrator, absent manifest error, shall be final and binding on the parties, effective as of the date the Accounting Arbitrator’s written opinion is received by Purchaser and Newpark. Purchaser and Newpark shall each pay their own respective costs and expenses in connection with the foregoing dispute resolution process, but all fees and expenses of the Accounting Arbitrator shall be paid by the party whose proposed Post-Closing EBITDA and Measurement Period Earn-Out Payment is farthest from the final Post-Closing EBITDA and Measurement Period Earn-Out Payment as determined by such Accounting Arbitrator. Any dispute as to which party’s proposed Post-Closing EBITDA and Measurement Period Earn-Out Payment is closest to the final Post-Closing EBITDA and Measurement Period Earn-Out Payment shall be resolved by the Accounting Arbitrator and shall be specified in the final report prepared by such Accounting Arbitrator.

     (iv) Prior to the date that is the earlier of (A) ten (10) days following the final determination of the Measurement Period Earn-Out Payment in accordance with this Section 2.5(d) (whether by failure of Newpark to deliver an Earn-Out Dispute Notice

within the required time period, by agreement of the parties, or by receipt of an opinion of the Accounting Arbitrator), and (B) one hundred fifty (150) days following the end of the relevant Measurement Period, Trinity and/or Purchaser shall pay to Newpark an amount in cash equal to the Measurement Period Earn-Out Payment as finally determined in accordance with this Section 2.5(d); provided, however, that if payment is to be made pursuant to clause (B) and the Measurement Period Earn-Out Payment shall not have been finally determined as of the date which is one hundred fifty (150) days following the end of the relevant Measurement Period, Trinity and/or Purchaser shall pay to Newpark the Measurement Period Earn-Out Payment as proposed in the Trinity Earn-Out Statement and within ten (10) days following the final determination of the Measurement Period Earn-Out Payment, (x) Trinity and/or Purchaser shall pay to Newpark any additional amounts which may be payable for such Measurement Period, or (y) Newpark shall return to Trinity and/or Purchaser, as the case may be, any excess amount received by Newpark for such Measurement Period.

     (e) Accelerated Earn-Out Payment. Notwithstanding anything herein to the contrary, if during any of the first five (5) Measurement Periods (1) Trinity, MBP or the Purchaser undergoes a Trinity Change of Control, or (2) Trinity, MPB or the Purchaser undertakes a Recapitalization, Trinity and/or Purchaser shall pay to DFI and Newpark Texas an aggregate amount equal to the Maximum Earn-Out Amount less the aggregate amount of any Measurement Period Earn-Out Payments paid to Newpark, DFI, and Newpark Texas prior to such Recapitalization or Trinity Change in Control (such difference, the “Accelerated Earn-Out Payment”). The Accelerated Earn-Out Payment shall be payable concurrently with the consummation of the Trinity Change of Control or Recapitalization. For purposes of this Agreement, a “Trinity Change of Control” shall mean (A) a merger or consolidation of Trinity, MBP or Purchaser with or into any other corporation or other entity or Person or (B) a sale, lease, exchange or other transfer in one transaction or series of related transactions of all or substantially all of Trinity’s, MBP’s or Purchaser’s outstanding securities or all or substantially all of Trinity’s, MBP’s or Purchaser’s assets; provided, that the following events shall not constitute a “Trinity Change of Control”: (i) a merger or consolidation of Trinity, MBP or Purchaser in which the holders of the voting securities of such entity immediately prior to the merger or consolidation hold at least a majority of the voting securities in the successor corporation immediately after the merger or consolidation; (ii) a sale, lease, exchange or other transfer in one transaction or a series of related transactions of all or substantially all of Trinity’s, MBP’s or Purchaser’s assets to a wholly-owned subsidiary of Trinity; (iii) in the case of Trinity and/or MBP, any merger, consolidation, contribution by or reorganization of Trinity and/or MBP in which all of such entity’s operating assets are merged into, consolidated with or otherwise contributed to Purchaser or any Affiliate of Purchaser; or (iv) the reincorporation of Trinity, MBP or Purchaser. For purposes of this Agreement, a “Recapitalization” shall mean a transaction or series of related transactions pursuant to which Trinity, MBP or Purchaser receives additional debt and/or equity financing (other than additional draws pursuant to their respective credit facilities) in an aggregate amount equal to or in excess of $15,000,000.

     (f) By execution of this Agreement, Trinity acknowledges and agrees that Trinity is, together with Purchaser, primarily liable for the payment of any Earn-Out Consideration that may be payable to Newpark pursuant to this Section 2.5 and that Newpark, DFI and Newpark Texas may proceed directly against Trinity for the recovery of any Earn-Out Consideration that

may be payable pursuant to this Section 2.5; provided, however, that nothing in this Section 2.5 shall prohibit or prevent any merger, consolidation, contribution by or reorganization of Trinity in which (i) all of Trinity’s operating assets are merged into, consolidated with or otherwise contributed to Purchaser or any Affiliate of Purchaser, and (ii) all of Trinity’s rights and liabilities under this Agreement are assigned to such successor in interest to Trinity’s assets in accordance with the provisions of Section 11.6 hereof. The provisions of this Section 2.5 shall not be subject to the provisions of Article X hereof or any limitations of liability set forth therein.

     2.6 Purchase Price Allocation. The parties agree to allocate the Purchase Price (including, for purposes of this Section 2.6, any other consideration treated for U.S. federal income tax purposes as being paid to Newpark, including any applicable liabilities assumed or taken subject to) among the assets of the Transferred Entities in accordance with an allocation schedule to be prepared by Purchaser in accordance with this Section 2.6. Within thirty (30) days of the final determination of the Closing Date Net Working Capital and Final Working Capital Adjustment, Purchaser shall deliver to Newpark an allocation statement setting forth Purchaser’s allocation of the Purchase Price pursuant to Section 1060 of the Code and any other applicable Tax Laws (as the same may be revised pursuant to this Section 2.6, the “Allocation Statement”). Within forty-five (45) days following its receipt of the Allocation Statement, Newpark shall have the right to dispute any such proposed allocation; otherwise, such proposed allocation shall become final. If Newpark so disputes any such allocation and Purchaser and Newpark are unable to resolve their disagreement within the forty-five (45) days following notification of such dispute, the dispute shall be submitted to the Accounting Arbitrator, whose expense shall be borne equally by Purchaser and Newpark, for resolution within forty-five (45) days of such submission. The decision of the Accounting Arbitrator with respect to such dispute shall be binding upon Purchaser and Newpark. Purchaser and Newpark (i) shall be bound by the allocations determined pursuant to this Section 2.6 for purposes of determining any Taxes; (ii) shall prepare and file all Tax Returns (such as IRS Form 8594 or other Tax Returns required by Section 1060 of the Code) to be filed with any Tax authority in a manner consistent with such allocation; and (iii) shall take no position inconsistent with such allocations in any Tax Return, any proceeding before any Tax authority or otherwise. In the event that any such allocation is disputed by any Tax authority, the party receiving notice of such dispute shall promptly notify and consult with the other party hereto concerning resolution of such dispute.

     2.7 Further Assurances. At any time and from time to time after the Closing Date, each party hereto shall, at the request of another party and at such requesting party’s sole cost and expense, execute and deliver such other instruments of conveyance and transfer and take such other actions as such other party may reasonably request in order to more effectively consummate the transactions contemplated hereby and to vest in the Purchaser title to all of the rights, title and interest of DFI and Newpark Texas, as applicable, in and to the Transferred Interests.

In the event and for so long as each party actively is prosecuting, contesting or defending any Action by a third party in connection with (a) any transactions contemplated under this Agreement or (b) any fact, situation, circumstance, status, condition, activity, practice, plan, occurrence, event, incident, action, failure to act, or transaction involving the Business or the Transferred Entities, and any of the foregoing require the other party’s cooperation due to such party’s ownership of the Business or the Transferred Entities at a relevant time, the requested party shall, and shall cause its Subsidiaries and controlled Affiliates to, cooperate reasonably with the requesting party and its counsel, at the requesting party’s expense for any out-of-pocket expenses, in the prosecution, contest or defense, make available its personnel, and provide such testimony and access to its books and records as shall be reasonably necessary in connection with the prosecution, contest or defense, subject to appropriate confidentiality measures.

     5.12 Noncompetition; Nonsolicitation.

     (a) For the period commencing on the Closing Date and ending on the earlier of (i) the fifth anniversary of the Closing Date, or (ii) a Newpark Change of Control (the “Restricted Period”) neither Newpark nor any of its Subsidiaries shall, except as permitted by this Section 5.12, engage in the business of providing environmental services in the oil and gas industry in the United States and Gulf of Mexico including, without limitation, waste management and disposal services and the processing and disposal of non-Hazardous Materials and NORM for generators in the United States including refiners, manufacturers, service companies and industrial municipalities as conducted by the Business as of the Closing Date (the “Covered Business”); provided, that the Covered Business shall not include the processing and disposal of environmental wastes and the providing and performance of waste management, reclamation and disposal services in a manner substantially similar to those which are currently provided by Newpark and its Subsidiaries (other than the Transferred Entities), which includes but is not limited to (i) the collection and disposal of oil and gas industry water (typically salt water contaminated with oil) that is exempt from RCRA, with operations in Oklahoma and the panhandle of Texas which are currently part of Newpark’s Fluids Systems and Engineering segment, operating under the name of Mid-Continent Completion Fluids, and (ii) the management of environmental waste utilizing pits and other earth structures, land farming, annular injection and offsite disposal of pit waste including the handling of NORM for the oil and gas industry which is currently part of Newpark’s Mats and Integrated Service segment,

which was historically known as Soloco. This Section 5.12(a) shall cease to be applicable to any Person at such time as it is no longer an Affiliate or Subsidiary of Newpark.

     (b) Notwithstanding the provisions of Section 5.12(a), nothing in this Agreement shall preclude, prohibit or restrict Newpark or any of its Affiliates or Subsidiaries from (i) acquiring, owning or holding up to 10% of the outstanding securities of any entity whose securities are listed and traded on a national securities exchange or market or any securities required to be registered under the Securities Exchange Act of 1934; or (ii) engaging in any manner in any business activity that would otherwise violate this Section 5.12 that is acquired from any Person (an “Acquired Business”) or is carried on by any Person that is acquired by or combined with Newpark or a Subsidiary of Newpark at any time during the Restricted Period (an “Acquired Company”); provided, that, if the aggregate consolidated revenues of the Acquired Business or the Acquired Company for the fiscal year ending prior to the completion of such purchase or acquisition is in excess of 5% of the consolidated revenues of Newpark and its Subsidiaries for the fiscal year ending prior to such purchase or acquisition (the “Divestiture Threshold”), then, as soon as promptly practicable, Newpark or such Subsidiary shall dispose or agree to dispose of all or a portion of the Acquired Business or the Acquired Company so that the aggregate consolidated revenues for the fiscal year ending prior to the completion of such purchase or acquisition of the remaining portion of the Acquired Business or the Acquired Company shall be less than the Divestiture Threshold.

     (c) During the Restricted Period, neither Newpark nor any of its Subsidiaries shall, directly or indirectly, solicit for employment or employ any Transferred Employee (other than any Person set forth in Section 5.12(c) of the Newpark Disclosure Schedule); provided, however, that this Section 5.12(c) shall not prohibit Newpark or any of its Subsidiaries from making general solicitations not specifically targeted at the Transferred Employees and employ persons in connection with such general solicitations or, on and after the first anniversary of the Closing Date, from employing or hiring any person who initiates discussions regarding employment without any solicitation by Newpark or any of its Subsidiaries.

     5.13 Labor Matters.

     (a) Following the Closing until ninety (90) days thereafter, neither the Purchaser, the Transferred Entities nor any Affiliates thereof shall cause any “employment losses” (as that term is defined in the Worker Adjustment and Retraining Notification Act (“WARN Act”)) that would give rise to any obligations or liabilities of Newpark or its Affiliates under the WARN Act.

     (b) Newpark, Newpark Texas and the Purchaser shall cooperate in connection with any required notification to, or any required consultation with, the employees, employee representatives, work councils, unions, labor boards and relevant Governmental Entities concerning the transactions contemplated by this Agreement.

     5.14 Environmental Inspection.

     (a) Promptly following the execution of this Agreement, Purchaser shall commence its review of the environmental condition of the assets of the Transferred Entities. The parties agree that the environmental site assessment shall be performed for each of the Owned Real

Property and Leased Real Property sites as Purchaser may determine and that such assessment shall conform, in all material respects, to the standard of the “Standard Practice for Environmental Site Assessments: Phase I Environmental Site Assessment Process,” known as ASTM E1527-05 (“ASTM E1527-05”). In connection with such environmental site assessment, Newpark shall, and shall cause each of the Transferred Entities to, reasonably cooperate with Purchaser and provide to Purchaser and its representatives copies of such records and documents (in addition to the “helpful documents” as defined below) as may be reasonably requested. Newpark shall identify a “key site manager” with “good knowledge of the uses and physical characteristics of the property,” both as defined in ASTM E1527-05, for purposes of the required interview with respect to the Owned Real Property and Leased Real Property. Interviewees shall be as specific as reasonably possible to the extent of their knowledge, and shall answer in good faith to the extent of their knowledge pursuant to and as defined in ASTM E1527-05. The key site manager shall promptly identify and provide the Purchaser and its representatives all “helpful documents” (as defined in ASTM E1527-05) that are within the possession or control of such key site manager.

     (b) As soon as reasonably practicable, but in any event no later than sixty (60) days following the execution of this Agreement (the “Environmental Inspection Period”), Purchaser shall (i) provide to Newpark a copy of each environmental report received by Purchaser relating to the Phase I environmental site assessments (individually, a “Phase I Report” and collectively, the “Phase I Reports”), and (ii) notify Newpark in writing of any alleged “recognized environmental conditions” (as defined in ASTM E1527-05) adversely affecting any Owned Real Property or Leased Real Property (any environmental conditions reflected in a Phase I Report or identified in such notice is referred to as an “Alleged Recognized Environmental Condition”). The notice (“Notice of Alleged Recognized Environmental Conditions”) shall include a description and reasonably detailed explanation (including all reports and other supporting documentation) of each Alleged Recognized Environmental Condition being claimed, and a value that Purchaser, in good faith, attributes to each Alleged Recognized Environmental Condition. Except as otherwise provided in this Section 5.14(b), Newpark and Purchaser shall promptly meet in an attempt to mutually agree upon a proposed resolution of any such Alleged Recognized Environmental Conditions and the costs related thereto. If Purchaser and Newpark are not able to agree upon a proposed resolution of any Alleged Recognized Environmental Condition and the costs related thereto on or before the date that is five (5) days prior to the Outside Date, such dispute shall be resolved by arbitration in accordance with Section 5.14(d) below. If as a result of any Phase I Report facts are revealed that would reasonably necessitate a Phase II environmental site assessment that includes the sampling and analysis of soil, groundwater and/or other environmental media to evaluate any Alleged Recognized Environmental Condition (individually, a “Phase II Report” and collectively, the “Phase II Reports”), Purchaser may require the completion of any such Phase II Report before Purchaser is required to meet with Newpark as hereinabove provided to agree upon a proposed resolution of any Alleged Recognized Environmental Condition. Any such Phase II Report shall be completed within sixty (60) days following the date of the Phase I Report relating to the subject property, but in no event later than one hundred twenty (120) days following the execution of this Agreement. Newpark and Purchaser shall promptly meet following the completion of any Phase II Reports in an attempt to mutually agree upon a proposed resolution of any Alleged Recognized Environmental Conditions and the costs related thereto. If Purchaser and Newpark

are not able to agree upon a proposed resolution within five (5) days, such dispute shall be resolved by arbitration in accordance with Section 5.14(d) below.

     (c) In the event a Phase I Report or a Phase II Report (collectively, an “Environmental Report”) shall identify an Alleged Recognized Environmental Condition and/or Purchaser shall provide Newpark a Notice of Alleged Recognized Environmental Condition in accordance with Section 5.14(b), the following provisions shall apply:

     (i) If the aggregate cost to resolve any and all Alleged Recognized Environmental Conditions as finally determined in accordance with this Section 5.14 (the “Alleged Recognized Environmental Cost”) is less than $1,000,000, (A) Purchaser shall assume all risks and responsibilities with respect to such Alleged Recognized Environmental Conditions and shall have no right to seek indemnification under Article X with respect thereto, (B) the total amount of the Earn-Out Consideration payable pursuant to Section 2.5 shall be reduced by an amount equal to the Alleged Recognized Environmental Cost, (C) the Initial Closing Consideration shall not be adjusted as a result of any such Alleged Recognized Environmental Cost, and (D) Purchaser shall have no right to terminate this Agreement as a result of such Alleged Recognized Environmental Conditions.

     (ii) If the Alleged Recognized Environmental Cost is equal to or greater than $1,000,000 and less than $2,000,000, (A) Purchaser shall assume all risks and responsibilities with respect to such Alleged Recognized Environmental Conditions and shall have no right to seek indemnification under Article X with respect thereto, (B) the total amount of the Earn-Out Consideration payable pursuant to Section 2.5 shall be reduced by the amount of $1,000,000, (C) the Initial Closing Consideration shall be reduced by the amount of the Alleged Recognized Environmental Cost in excess of $1,000,000, and (D) Purchaser shall have no right to terminate this Agreement as a result of such Alleged Recognized Environmental Conditions.

     (iii) If the Alleged Recognized Environmental Cost is equal to or greater than $2,000,000, Newpark shall have the option to cure or otherwise remediate, at its sole cost and expense, a portion of the Alleged Recognized Environmental Conditions in accordance with this Section 5.14(c)(iii) by providing Purchaser written notice thereof within five (5) days of the final determination of the Alleged Recognized Environmental Costs pursuant to this Section 5.14. If Newpark fails to timely exercise its option as herein provided, Purchaser shall have the right to terminate this Agreement upon written notice to Newpark. If Newpark does exercise its option to cure or remediate under this Section 5.14(c)(iii), Newpark shall undertake to cure or remediate one or more of the Alleged Recognized Environmental Conditions selected by Newpark (the “Selected Alleged Recognized Environmental Conditions”) so that the aggregate Alleged Recognized Environmental Cost for the remaining Alleged Recognized Environmental Conditions (the “Remaining Alleged Recognized Environmental Conditions”) does not equal or exceed $2,000,000. Newpark shall complete the cure or remediation of the Selected Alleged Recognized Environmental Conditions as soon as practicable but in any event not later than six (6) months following the date Newpark delivers Purchaser notice of Newpark’s election to exercise the option herein to cure or remediate the Selected

Alleged Recognized Environmental Conditions. If, following the cure or remediation of the Selected Alleged Recognized Environmental Conditions, the Alleged Recognized Environmental Cost of the Remaining Alleged Recognized Environmental Conditions is more than $1,000,000 but less than $2,000,000, (A) Purchaser shall assume all risks and responsibilities with respect to such Remaining Alleged Recognized Environmental Conditions and shall have no right to seek indemnification under Article X with respect thereto, (B) the total amount of the Earn-Out Consideration payable pursuant to Section 2.5 shall be reduced by the amount of $1,000,000, (C) the Initial Closing Consideration shall be reduced by the amount of the Alleged Recognized Environmental Cost for the Remaining Alleged Recognized Environmental Conditions in excess of $1,000,000, and (D) Purchaser shall have no right to terminate this Agreement as a result of such Remaining Alleged Recognized Environmental Conditions. If, following the cure or remediation of the Selected Alleged Environmental Conditions, the Alleged Recognized Environmental Cost of the Remaining Alleged Recognized Environmental Conditions is less than $1,000,000, (A) Purchaser shall assume all risks and responsibilities with respect to such Remaining Alleged Recognized Environmental Conditions and shall have no right to seek indemnification under Article X with respect thereto, (B) the total amount of the Earn-Out Consideration payable pursuant to Section 2.5 shall be reduced by an amount equal to the Alleged Recognized Environmental Cost of the Remaining Alleged Recognized Environmental Conditions, (C) the Initial Closing Consideration shall not be adjusted as a result of any such Alleged Recognized Environmental Cost, and (D) Purchaser shall have no right to terminate this Agreement as a result of such Remaining Alleged Recognized Environmental Conditions.

     (d) Any dispute relating to an Alleged Recognized Environmental Condition and the cost of any proposed or acceptable resolution thereof (an “Environmental Dispute”), shall be settled by binding arbitration. Any such arbitration proceeding shall be conducted by one arbitrator mutually agreeable to Newpark and Purchaser. In the event that within ten (10) Business Days after submission of any Environmental Dispute to arbitration, Newpark and Purchaser cannot mutually agree on one arbitrator, Newpark and Purchaser shall each select one arbitrator, and the two arbitrators so selected shall select a third arbitrator who will arbitrate the Environmental Dispute on his own. The decision of the arbitrator shall be binding and conclusive upon the parties to this Agreement. Such decision shall be written and shall be supported by written findings of fact and conclusions which shall set forth the determination of such arbitrator. Any such arbitration shall be held in Houston, Texas, under the commercial rules then in effect of the American Arbitration Association. Newpark and Purchaser shall equally share the fees of the arbitrator and applicable administrative fees and shall otherwise pay their respective costs and expenses in connection therewith.

     5.15 Post-Closing Covenants.

     (a) Not later than sixty (60) days following the Closing, Purchaser shall either (i) cause Newpark to be fully and unconditionally released in a writing reasonably satisfactory to Newpark from all obligations of Newpark under that certain Corporate Guaranty dated December 23, 2005 by and between Newpark and General Electric Capital Corporation (the “Corporate Guaranty”), or (ii) fully satisfy and discharge all obligations to which the Corporate Guaranty relates and provide Newpark with evidence thereof satisfactory to Newpark.

     (b) Promptly following the Closing, Newpark and Purchaser shall cooperate in good faith to obtain the consent of the Greater LaFourche Port Commission to the sublease of that certain tract of land described in Section 5.15(b) of the Newpark Disclosure Schedule by NESI to DFI and upon receipt of such consent, Purchaser (or NESI) and DFI shall enter into a sublease agreement (the “Fourchon Sublease”) consistent with the terms and provisions set forth in Section 5.15(b) of the Newpark Disclosure Schedule and otherwise in a form mutually acceptable to Newpark and Purchaser.

ARTICLE VI
EMPLOYEE MATTERS COVENANTS

     6.1 Employees and Compensation.

     (a) Newpark shall update Section 3.10(f) of the Newpark Disclosure Schedule as of two (2) Business Days prior to the Closing Date to reflect the Transferred Employees as of the Closing Date.

     (b) Except as set forth on Schedule 6.1(b) of the Newpark Disclosure Schedule, from the Closing Date through the first anniversary of the Closing Date, Purchaser shall provide, or shall cause the Transferred Entities to provide, the Transferred Employees with compensation (including bonuses, commissions and/or other annual incentive opportunities) and employee benefits that in the aggregate are not substantially less favorable than the compensation and benefits provided by Newpark and its Affiliates as of immediately prior to the Closing Date and as set forth in Sections 3.10(a), 3.10(f) and 6.2(f) of the Newpark Disclosure Schedule. Nothing in the foregoing provision or otherwise shall in any way alter the “at will” nature of the employment relationship between any Transferred Employee, on the one hand, and any Transferred Entity, on the other hand.

     6.2 Welfare Benefits Plans.

     (a) Effective as of the Effective Time and to the extent permitted by applicable Law, Purchaser shall permit each Transferred Employee to enroll in Welfare Plans provided by Purchaser or its Affiliates to their employees on the Closing Date which are consistent with Section 6.1(b).

     (b) Subject to the provisions of Section 6.2(a) and the conditions stated below, with respect to the coverage of the Transferred Employees under the group health plans provided by Purchaser or its Affiliates, (i) each such employee’s credited service with Newpark and its Affiliates shall be credited against any waiting period applicable to eligibility for enrollment of new employees under Purchaser’s group health plans; (ii) limitations on benefits due to pre-existing conditions shall be waived (or, if such a waiver is not otherwise required by applicable Laws, Purchaser shall use commercially reasonable efforts to have them waived), to the extent waived under the corresponding Benefit Plan for any Transferred Employee enrolled in any group health plan maintained by Newpark and its Affiliates as of the Closing Date; and (iii) any out of pocket annual maximums and deductibles taken into account under the Newpark group health plan for any Transferred Employee from and after March 1, 2007 to the Closing Date, shall to the extent permitted under Purchaser’s group health plans, be credited under said group

health plans. Notwithstanding anything to the contrary herein, Purchaser’s obligations in this Section 6.2(b) are subject to and conditioned upon satisfaction of all of the following conditions: (i) copies of all group health plan records pertaining to out of pocket annual maximums, deductibles and similar costs incurred by Transferred Employees under the Newpark group health plans shall be provided to the insurance carriers providing group health benefits to employees of Purchaser or its Affiliates; (ii) only expenses incurred from and after March 1, 2007 through the end of the current plan year for Purchaser’s group health plans, or February 28, 2008, will be credited; and (iii) the insurance carriers that provide group health benefits to Purchaser’s employees shall receive certificates of creditable coverage for all of the Transferred Employees and their dependents.

     (c) Purchaser shall be responsible for providing the notices and making available COBRA Continuation Coverage for all Transferred Employees and their respective covered dependents whose qualifying events (as defined in Code Section 4980B) occur on or after the Closing Date. Newpark shall continue to be responsible for providing the notices and making available COBRA Continuation Coverage, for all of the Former Employees and their respective covered dependents whose qualifying events (as defined in Code Section 4980B) occur prior to the Closing Date.

     (d) Notwithstanding anything in this Agreement to the contrary, if any Transferred Employee has become disabled (within the meaning of the applicable Welfare Plan maintained by Newpark or its Affiliates that provides short-term or long-term disability benefits) prior to the Closing Date, Newpark and/or its Affiliates will retain liability for the provision of disability benefits payable to such Transferred Employee under Newpark’s Welfare Plans, if any, with respect to such disability (but not with respect to any reoccurrence of such a disability after such Transferred Employee returns to active service on or following the Closing Date). From and after the Closing Date, any right to reemployment for any Transferred Employees who are on short-term or long-term disability as of immediately prior to the Effective Time shall be the obligation of Purchaser and its Affiliates and not of Newpark and its Affiliates.

     (e) From and after the Effective Time, (i) Purchaser shall assume and honor or shall cause the Transferred Entities to assume and honor, all unpaid vacation or other paid time off days of the Transferred Employees that accrued prior to the Effective Time, and (ii) Purchaser shall sponsor a vacation and paid time off policy that applies to each Transferred Employee and shall take into account service with Newpark and its Affiliates as provided in Section 6.3(a).

     (f) Subject to the limitations set forth in Section 2.1(b)(ii), Purchaser shall provide Transferred Employees whose employment is terminated during the six-month period immediately following the Closing Date severance pay and benefits on the terms and conditions set forth in Section 6.2(f) of the Newpark Disclosure Schedule. Notwithstanding the foregoing, Purchaser and the Transferred Entities shall not be under any obligation to continue the employment of any individual for any period of time following the Closing as a result of any provision of this Agreement.

     6.3 Miscellaneous Employee Issues.

     (a) For all purposes under the employee benefit plans, practices or arrangements of Purchaser and its Affiliates (including the Transferred Entities) providing benefits to any Transferred Employee after the Closing Date, each Transferred Employee shall be credited with all years of service for which such Transferred Employee was credited before the Effective Time under any similar employee benefit plans, practices or arrangements of Newpark and its Affiliates.

     (b) No provision of this Agreement shall create any third party beneficiary or other rights in any employee (including any beneficiary or dependent thereof) or any other persons in respect of continued employment with any of Newpark, Newpark Texas, Purchaser or the Transferred Entities or any of their respective Affiliates, and no provision of this Agreement shall create any such rights in any such persons with respect to any benefits that may be provided, directly or indirectly, under any Plan, policy or arrangement which may be established or maintained by Newpark, Newpark Texas, the Transferred Entities or Purchaser.

     (c) Notwithstanding anything to the contrary herein, Newpark and its Affiliates hereby covenant and agree that, following the Closing, any confidentiality provision in any agreement between Newpark or any Affiliate and any Transferred Employee, together with any confidentiality obligation of any Transferred Employee arising under the Law in favor of Newpark and its Affiliates, shall not prohibit any such Transferred Employee’s use, post-Closing, of any confidential information solely relating to the Business and for the benefit of the Transferred Entities and their Affiliates. In addition, Newpark and its Affiliates hereby covenant and agree that any non-competition provision in any agreement between Newpark or any Affiliate and any Transferred Employee shall not prohibit a Transferred Employee’s activities, post-Closing, solely relating to the Business and for the benefit of the Transferred Entities and their Affiliates. Any Transferred Employee that, in the absence of this Agreement, would be bound by any such confidentiality or non-competition provisions in favor of Newpark and its Affiliates post-Closing, shall be a third-party beneficiary of this Agreement solely with respect to this Section 6.3(c).

ARTICLE VII
TAX MATTERS

     7.1 Liability for Taxes and Related Matters.

     (a) Newpark Liability for Taxes. Except for the amounts recorded as a liability in the calculation of the Estimated Net Working Capital, as adjusted by the Closing Date Net Working Capital, Newpark shall be liable for and indemnify Purchaser for all Taxes imposed on or due from the Transferred Entities (i) for any taxable year or period that ends on or before the Closing Date (a “Pre-Closing Period”), and (ii) with respect to any taxable year or period beginning before and ending after the Closing Date (a “Straddle Period”), the portion of such taxable year ending on and including the Closing Date. Newpark shall be entitled to any refund of Taxes of the Transferred Entities received for any Pre-Closing Period and any portion of a Straddle Period ending on and including the Closing Date.

     (b) Purchaser Liability for Taxes. Purchaser shall be liable for and indemnify Newpark for all Taxes imposed on or due from the Transferred Entities for any taxable year or period that begins after the Closing Date (a “Post-Closing Period”) and, with respect to any Straddle Period, the portion of such taxable year beginning after the Closing Date.

     (c) Taxes for Straddle Periods. To the extent permitted by Law or administrative practice, the taxable year of the Transferred Entities shall be closed at the Effective Time. To the extent that the taxable year of the Transferred Entities is not closed pursuant to the previous sentence and it is therefore necessary to determine the liability for Taxes for a Straddle Period, the determination of the Taxes for the portion of the year or period ending on, and for the portion of the year or period beginning after, the Closing Date shall be determined by assuming that the Transferred Entities had a taxable year or period which ended at the Effective Time, except that exemptions, allowances or deductions that are calculated on an annual basis (other than net operating losses and tax credits carried forward from years ending prior to the Closing Date), shall be prorated on the basis of the number of days in the annual period elapsed through the Closing Date as compared to the number of days in the annual period elapsing after the Closing Date. Net operating losses and tax credits carried forward from years ending prior to the Closing shall be allocated first, to the extent that they can be utilized, to the taxable year or period ending on the Closing Date.

     (d) Adjustment to Purchase Price. Any payment by Purchaser or Trinity, on the one hand, or Newpark, on the other hand, pursuant to Section 2.4, Section 2.5 or Article X and any Tax indemnification payment pursuant to this Section 7.1 will be treated as an adjustment to the Purchase Price for all Tax purposes. The indemnification obligations contained in Sections 7.1(a) and 7.1(b) above shall survive the Closing Date until seventy-five (75) days following the expiration of the statutory periods of limitations (including any extensions to such limitations periods agreed to by Newpark or the Purchaser, as the case may be).

     (e) Tax Returns. Newpark shall file, or cause to be filed, when due all Tax Returns that are required to be filed by or for the Transferred Entities for taxable years or periods ending on or before the Effective Time, and Purchaser shall file, or cause to be filed, when due all Tax Returns that are required to be filed by or for the Transferred Entities for taxable years or periods ending after the Effective Time. If Newpark could be liable for any Taxes with respect to any Tax Return filed by Purchaser, Purchaser shall (i) cause such Tax Return to be prepared on a basis which is consistent with the Transferred Entities’ Tax Returns previously filed and in accordance with past practices unless otherwise required (rather than permitted) by the Code and/or Treasury Regulations at such time, (ii) deliver a copy of such Tax Return along with accompanying work papers to Newpark not less than thirty (30) days prior to the due date (as extended, if applicable) for the filing of such Tax Return (the “Due Date”), (iii) if, at any time prior to the Due Date, Newpark notifies Purchaser that Newpark objects to any item reflected on such Tax Return which item may affect Newpark’s liability for Taxes, Purchaser shall, prior to the Due Date, make any and all changes to such item or items reasonably requested by Newpark and Purchaser shall not file any such Tax Return until it has made such reasonable changes and received Newpark’s agreement thereto (not to be unreasonably withheld). If Purchaser has fully complied with this Section 7.1(e) with respect to a Tax Return to be filed by Purchaser, Newpark shall pay Purchaser the Taxes for which Newpark is liable pursuant to Section 7.1(a) but which are payable with such Tax Return within five (5) Business Days (x) prior to the Due Date for the

filing of such Tax Returns or (y) after the date that Purchaser has provided Newpark with the revised Tax Return referred to in clause (iii) of the previous sentence, whichever is later. If Purchaser fails to satisfy any of its obligations pursuant to this Section 7.1(e) with respect to any Tax Return, Newpark shall, in addition to any other remedies available to Newpark, have no obligation to indemnify Purchaser for any Taxes reflected on such Tax Return.

     (f) Contest Provisions. Purchaser shall promptly notify Newpark in writing upon receipt by Purchaser, any of its Affiliates or the Transferred Entities of notice of any pending, proposed, threatened or actual Tax audit or Tax deficiency, assessment or other claim which may affect the Taxes for any Pre-Closing Period or any Straddle Period for which Newpark would be liable pursuant to Section 7.1(a). Newpark shall promptly notify Purchaser in writing upon receipt by Newpark, Newpark Texas or any of their Affiliates of notice of any pending, proposed, threatened or actual Tax audit or Tax deficiency, assessment or other claim which may affect the Taxes for any Straddle Period for which Purchaser would be liable pursuant to Section 7.1(b). Newpark shall have the sole right to control the defense in any Tax audit or administrative court proceeding (a “Tax Contest”) relating to any Pre-Closing Period and to employ counsel and other advisors of its choice at its expense, provided that Purchaser (together with its counsel and other advisors) shall be entitled, at its sole cost, to participate in (but not control) any proceeding relating to any such Pre-Closing Period. In the event Newpark shall have the right to control any such Tax Contest, Purchaser shall, upon request of Newpark, execute any such document and take such other action as may be reasonably requested by Newpark to obtain an extension of the period during which the taxable year or period to which such Tax Contest relates remains subject to further audit or examination. In the event of any Tax Contest relating to a Straddle Period of the Transferred Entities, (i) to the extent the issues can be separated into those for which Newpark would be liable under Section 7.1(a) and those for which Purchaser would be liable under Section 7.1(b), then each of Newpark, on the one hand, and Purchaser, on the other, shall control the defense of those issues for which it would be liable, employing counsel and other advisors of its own choice, at its expense, (ii) with respect to all other issues, Purchaser shall be entitled to control the defense employing counsel and other advisors of its choice at its expense, provided that Newpark (along with counsel and other advisors of its choice) shall be entitled to participate in the defense of and to take over such defense if Purchaser is not prosecuting the defense diligently, vigorously and professionally. Neither Purchaser nor the Transferred Entities may agree to settle any Tax claim which may affect the Taxes for which Newpark or its Affiliates would be liable under Section 7.1(a) without the prior written consent of Newpark, which consent shall not be unreasonably withheld. Further, neither Newpark nor any of its Affiliates may agree to settle any Tax claim which may affect the Taxes for which Purchaser or the Transferred Entities would be liable under Section 7.1(b) without the prior written consent of Purchaser, which consent shall not be unreasonably withheld.

     7.2 Transfer Taxes. Any transfer taxes (excluding income taxes or capital gain taxes) arising from the sale of the Acquired Interests shall be borne by Purchaser.

The Purchaser shall have received reasonable evidence that (i) the Transferred Interests and all assets held by the Transferred Entities shall have been released from any and all Liens (other than Permitted Liens), and (ii) the Transferred Entities shall have been released from all guaranties or other liability with respect to Newpark’s funded Indebtedness.

     (e) No Material Adverse Effect. No Material Adverse Effect shall have occurred, nor shall any event or circumstance have occurred which would reasonably be expected to have, individually or in the aggregate, a Material Adverse Effect.

     (f) FIRPTA. Newpark shall deliver to Purchaser at the Closing a duly executed and acknowledged certificate, in customary form and substance reasonably acceptable to Purchaser and in compliance with the Code and Treasury Regulations, certifying such facts as to establish that the sale of the Acquired Interests is exempt from withholding pursuant to Section 1445 of the Code.

     (g) Lafayette Sublease. Newpark Mats and Integrated Services LLC (“NMIS”) and NESI shall have entered into a sublease (the “Lafayette Sublease Agreement”) of the office space described in Section 8.2(g) of the Newpark Disclosure Schedule on terms and provisions consistent with those set forth on Section 8.2(g) of the Newpark Disclosure Schedule and otherwise in a form mutually acceptable to Newpark and Purchaser.

     (h) Environmental Reports. The environmental site assessments contemplated by Section 5.14 hereof shall have been completed and Purchaser shall have received the Environmental Reports contemplated by Section 5.14. For the avoidance of doubt, the condition represented by this Section 8.2(h) is limited to the completion of the environmental site assessments and delivery of the Environmental Reports and does not include Purchaser’s acceptance of the Environmental Reports or any Alleged Recognized Environmental Conditions identified therein. The parties acknowledge that the provisions of Section 5.14 shall control with respect to the resolution of any Alleged Recognized Environmental Conditions and Purchaser’s right to terminate this Agreement as a result of any such Alleged Recognized Environmental Conditions.

     (i) Other. Purchaser shall have received reasonable evidence of the satisfaction of any additional conditions to Purchaser’s obligations to close as set forth in Section 8.2(i) of the Newpark Disclosure Schedule.

     (a) Representations and Warranties. The representations and warranties of Purchaser set forth in this Agreement that are qualified as to materiality shall be true and correct and the representations and warranties of Purchaser set forth in this Agreement and that are not so qualified shall be true and correct in all material respects, in each case on the date of this Agreement and on the Closing Date as though made on the Closing Date, except those representations and warranties that address matters only as of a particular date or only with respect to a specific period of time, which need only be true and correct (or true and correct in all material respects, as applicable) as of such date or with respect to such period; provided, however, that a breach of any of the foregoing representations and warranties shall not constitute

the non-fulfillment of the foregoing condition if such breach is capable of cure and such breach is actually cured, by the earlier of (i) thirty (30) calendar days after written notice thereof from Newpark and (ii) the Outside Date.

     (b) Covenants and Agreements. The covenants and agreements of Purchaser to be performed or complied with on or before the Closing Date in accordance with this Agreement including, without limitation, the delivery of the items described in Section 2.3(b)(ii), shall have been duly performed or complied with in all material respects.

ARTICLE IX
TERMINATION

     9.1 Termination. This Agreement may be terminated at any time prior to the Closing:

     (a) by mutual written consent of Newpark and Purchaser;

     (b) by either Newpark, on the one hand, or Purchaser, on the other hand, if the Closing shall not have occurred on or before December 15, 2007 (the “Outside Date”); provided, however, that (i) either Newpark or Purchaser may, at its sole discretion, extend the Outside Date on one or more occasions for an aggregate period not to exceed forty-five (45) days if all other conditions to consummation of the transactions contemplated by this Agreement are satisfied or capable of then being satisfied, and the sole reason that such transactions have not been consummated by such date is that the condition set forth in Section 8.1(a) has not been satisfied, (ii) either Newpark or Purchaser may, at its sole discretion, extend the Outside Date up to sixty (60) days if a Phase II Report shall be required pursuant to Section 5.14(b) and such Phase II Report shall not have been completed, (iii) either Newpark or Purchaser may, at its sole discretion, extend the Outside Date (as same may have been extended pursuant to the preceding clause (ii)) on one or more occasions for an aggregate period not to exceed forty-five (45) days if one or more Environmental Disputes shall have been submitted to arbitration in accordance with Section 5.14(d), provided, that the Outside Date shall not be extended for a period in excess of five (5) Business Days following the date upon which the arbitrator shall have delivered his written decision with respect to such Environmental Disputes, (iv) either Newpark or Purchaser may, at its sole discretion, extend the Outside Date (as same may have been extended) up to six (6) months if Newpark exercises its option under Section 5.14(c)(iii) to cure or remediate the Selected Alleged Recognized Environmental Conditions, and (v) the right to terminate this Agreement under this Section 9.1(b) shall not be available to any party to this Agreement whose failure to comply or perform in any material respect with such party’s representations, warranties, covenants or other agreements contained in this Agreement has been the cause of or resulted in the failure of the transactions contemplated by this Agreement to occur on or before the Outside Date. In the event (A) any Environmental Report required pursuant to Section 5.14 hereof shall not have been completed on or before the Outside Date as it may have been extended pursuant to clause (ii) above, or (B) any Environmental Dispute shall not have been

resolved by arbitration or otherwise on or before the Outside Date as it may have been extended pursuant to clause (iii) above, Newpark shall have the right, at its discretion, to terminate this Agreement on the Outside Date (as same may have been extended). In the event Newpark shall not have completed the cure or remediation of the Selected Alleged Recognized Environmental Conditions on or before the Outside Date as it may have been extended pursuant to clause (iv) above, Purchaser shall have the right, at its discretion, to terminate this Agreement on the Outside Date (as the same may have been extended);

     (c) by Newpark at any time if (i) the representations and warranties of Purchaser in this Agreement that are qualified as to materiality were not true and correct or the representations and warranties of Purchaser in this Agreement that are not so qualified were not true and correct in all material respects when made or at any time thereafter, or (ii) Purchaser is in breach in any material respect of any of its covenants or other agreements in this Agreement (clauses (i) and (ii) collectively, a “Purchaser Breach”), and such Purchaser Breach continues uncured for thirty (30) calendar days after written notice thereof by Newpark; provided, however, that such thirty (30) day period shall not be extended past the Outside Date;

     (d) by Purchaser at any time if (i) the representations and warranties of Newpark in this Agreement that are qualified as to materiality were not true and correct or the representations and warranties of Newpark in this Agreement that are not so qualified were not true and correct in all material respects when made or at any time thereafter, or (ii) any one of Newpark, DFI or Newpark Texas are in breach in any material respect of any of their respective covenants or other agreements in this Agreement (clauses (i) and (ii) collectively, a “Newpark Breach”), and such Newpark Breach continues uncured for thirty (30) calendar days after written notice thereof by Purchaser; provided, however, that such thirty (30) day period shall not be extended past the Outside Date; or

     (e) by Purchaser pursuant to Section 5.14(c)(iii).

     9.2 Notice of Termination. In the event of termination of this Agreement by Newpark, on the one hand, or Purchaser, on the other hand, pursuant to Section 9.1, written notice of such termination shall be given by the terminating party to the other parties to this Agreement.

     9.3 Effect of Termination.

     (a) In the event of the termination of this Agreement pursuant to Section 9.1, this Agreement shall terminate and become void and have no effect, and the transactions contemplated by this Agreement shall be abandoned without further action by the parties to this Agreement, except that the provisions of Sections 5.1(a) (as they relate to the Confidentiality Agreement), 9.3, 11.2 and 11.4 shall survive the termination of this Agreement; provided, however, that such termination shall not relieve any party to this Agreement of any liability for breach of this Agreement and the terminating party’s right to pursue all legal remedies will survive such termination.

     (b) Notwithstanding anything in this Agreement to the contrary, if this Agreement is terminated pursuant to Section 9.1(b) (other than as a result of Newpark’s failure to complete the

cure or remediation of the Selected Alleged Recognized Environmental Conditions on or before the Outside Date as extended pursuant to clause (iv) of Section 9.1(b)) or Section 9.1(c), then Purchaser shall pay or cause to be paid to Newpark $1,000,000 (the “Termination Fee”) in immediately available funds as promptly as reasonably practicable (and in any event within two (2) Business Days following such termination) by wire transfer of same-day funds. The parties acknowledge and agree that if this Agreement is terminated pursuant to Section 9.1(b), except as provided above, or Section 9.1(c), Newpark’s damages would be difficult or impossible to quantify with reasonable certainty, and accordingly the payment of the Termination Fee provided for in this Section 9.3(b) is a payment of liquidated damages (and not penalties) which is based upon the parties’ estimate of the damages Newpark will suffer or incur as a result of the event giving rise to such payment and the resulting termination of this Agreement, and the payment of such Termination Fee by Purchaser as herein provided shall be the sole and exclusive remedy of Newpark in the event of any such termination.

ARTICLE X
SURVIVAL AND INDEMNIFICATION

     10.1 Survival Periods. Regardless of any investigation at any time made by or on behalf of any party hereto, or of any information any party may have in respect thereof, all representations and warranties, and all covenants that contemplate or may involve actions to be taken or obligations in effect prior to the Closing, in each case contained in this Agreement or in any Schedule to this Agreement, or in any certificate, document or other instrument delivered in connection with this Agreement, shall survive the Closing as herein provided; provided, however, that the right to commence any claim with respect thereto under Section 10.2(a), 10.2(b), 10.3(a) and 10.3(b), shall terminate and cease to be of further force and effect as of the date which is twenty-four (24) months following the Closing Date; and provided, further that (i) the representations and warranties set forth in Section 3.2 (Capitalization of the Transferred Entities), Section 3.3 (Authority Relative to this Agreement), Section 3.10 (Employee Benefits; Labor Matters), Section 3.11 (Brokers), Section 3.13 (Environmental Matters), Section 4.2 (Authority Relative to this Agreement), Section 4.5 (Brokers) and Section 4.6 (Acquisition of Transferred Interests), and the right to commence any claim with respect thereto under Section 10.2(a) and 10.3(a), shall survive the execution and delivery of this Agreement until the fifth anniversary of the Closing Date, and (ii) the representations and warranties set forth in Section 3.12 (Taxes), and the right to commence any claim with respect thereto under Section 10.2(a), shall survive until the sixth anniversary of the Closing Date. Those covenants that contemplate or may involve actions to be taken or obligations in effect after the Closing shall survive in accordance with their terms (the “Surviving Covenants”). Notwithstanding the foregoing, any covenant, agreement, representation, warranty or other matter in respect of which indemnity may be sought under this Agreement shall survive the time at which it would otherwise terminate pursuant to this Section 10.1, if notice of the inaccuracy or breach thereof or other matter giving rise to such right of indemnity shall have been given to the party against whom such indemnity may be sought prior to such time.

     10.2 Indemnification by Newpark, DFI and Newpark Texas. Subject to the terms and conditions of this Article X including the limitations set forth in Section 10.1 and Section 10.5 and the provisions of Section 5.14(c) relating to Alleged Recognized Environmental Costs, from and after the Closing Date, Newpark, DFI and Newpark Texas shall jointly and

severally indemnify and hold harmless Purchaser and its Affiliates, and each of their respective directors, officers, employees and agents (collectively, the “Purchaser Indemnified Parties”) from and against any and all Losses to the extent resulting from or arising out of:

     (a) any breach or inaccuracy of any representation or warranty of Newpark contained in this Agreement, other than those which have been waived in writing by Purchaser prior to the Closing;

     (b) any breach of any Surviving Covenant contained in this Agreement to be performed by Newpark, DFI or Newpark Texas after the Closing;

     (c) any Non-assumed Liabilities; or

     (d) the matters described in Section 10.2(d) of the Newpark Disclosure Schedule.

     10.3 Indemnification by Purchaser and Trinity. Subject to the terms and conditions of this Article X including the limitations set forth in Section 10.1 and Section 10.5, from and after the Closing Date, Purchaser and Trinity shall jointly and severally indemnify and hold harmless Newpark and its Affiliates, and each of their respective directors, officers, employees and agents, (collectively, the “Newpark Indemnified Parties” and together with Purchaser Indemnified Parties the “Indemnified Parties”) from and against any and all Losses resulting from or arising out of:

     (a) any breach or inaccuracy of any representation or warranty of Purchaser contained in this Agreement, other than those which have been waived in writing by Newpark, DFI and Newpark Texas prior to the Closing;

     (b) any breach of any Surviving Covenant contained in this Agreement to be performed by Purchaser or Trinity after the Closing; or

     (c) other than any Loss indemnifiable by Newpark, DFI or Newpark Texas under Section 10.2, any Losses of any Transferred Entity resulting from a claim of a third party arising out of or in connection with any of the businesses, properties, assets, operations or activities of any Transferred Entity or any of its Affiliates, heretofore, currently or hereafter owned or conducted, as the case may be.

     10.4 Third-Party Claims. If a claim by a third party is made against an Indemnified Party, and if such party intends to seek indemnity with respect thereto under this Article X, such Indemnified Party, shall promptly notify, in writing, Purchaser, if a Newpark Indemnified Party, or Newpark, if a Purchaser Indemnified Party (Purchaser and Trinity, or Newpark, DFI and Newpark Texas, as the case may be, the “Indemnifying Party”), of such claims. The failure to provide such written notice shall not result in a waiver of any right to indemnification hereunder except to the extent that the Indemnifying Party is actually and materially prejudiced by such failure. The Indemnifying Party shall have twenty (20) days after receipt of such notice to elect to undertake, conduct and control, through counsel of its own choosing and at its own expense, the settlement or defense thereof, and the Indemnified Party shall cooperate with it in connection therewith. Notwithstanding the foregoing, an Indemnified Party shall have the right to employ separate counsel at the Indemnifying Party’s expense and participate in (but not control) such

defense if the named parties to any such proceeding include both such Indemnified Party and the Indemnifying Party, and such Indemnified Party shall have been advised by counsel that a conflict of interest is likely to exist if the same counsel were to represent such Indemnified Party and the Indemnifying Party. Notwithstanding the foregoing, in no event shall an Indemnifying Party be required to pay the expenses of more than one (1) separate counsel. The Indemnified Party shall not pay or settle any claim without the prior written consent of the Indemnifying Party (which consent shall not be unreasonably withheld). Notwithstanding the foregoing, the Indemnified Party shall have the right to pay or settle any such claim; provided, that, in such event, it shall waive any right to indemnity therefor by the Indemnifying Party. The Indemnifying Party shall not, except with the consent of the Indemnified Party, (i) enter into any settlement that does not include, as an unconditional term thereof, the giving by the person or persons asserting such claim to all Indemnified Parties of an unconditional release from all liability with respect to such claim, or (ii) consent to entry of any judgment that imposes injunctive or equitable relief.

     10.5 Limitations.

     (a) No indemnity shall be payable to the Purchaser Indemnified Parties under Section 10.2(a) with respect to any claim resulting from any breach or inaccuracy of any representation or warranty, unless and until the aggregate of all Losses due from Newpark, DFI and/or Newpark Texas exceeds $1,500,000 (the “Deductible”), in which event all Losses so due in excess of the Deductible shall be paid in the aggregate by Newpark, ▇▇▇ ▇▇▇/▇▇ ▇▇▇▇▇▇▇ ▇▇▇▇▇; provided, that the aggregate amount payable by Newpark, DFI and Newpark Texas for all claims arising under this Agreement shall not exceed 33% of the Initial Closing Consideration. Notwithstanding anything to the contrary contained in this Agreement, neither Newpark, DFI nor Newpark Texas shall be required to indemnify any Purchaser Indemnified Party with respect to any Loss (or series of related Losses) incurred by or asserted by reason of any breach of any representation or warranty contained in this Agreement if the Loss (or series of related Losses) from such breach is less than (i) $75,000, if such Loss is incurred before such time as the aggregate amount of all Losses due from Newpark exceeds the Deductible, and (ii) $50,000 if such Loss is incurred after such time as the aggregate amount of all Losses due from Newpark exceeds the Deductible (the “Minimum Claim Amount”), nor shall any Losses less than the Minimum Claim Amount be included for purposes of calculating whether the Deductible has been exceeded. The limitations set forth in this Section 10.5(a) shall not apply with respect to (i) any amounts payable under Section 2.4, Section 2.5 or Losses arising under Section 10.2(b), Section 10.2(c), or Section 10.2(d) (except as otherwise indicated in Section 10.2(d) of the Newpark Disclosure Schedule), (ii) any breach of Section 5.12, and/or (iii) any acts of willful misconduct or fraud.

     (b) No indemnity shall be payable to the Newpark Indemnified Parties under Section 10.3(a) with respect to any claim resulting from any breach or inaccuracy of any representation or warranty, unless and until the aggregate of all Losses due from Purchaser and Trinity exceeds the Deductible, in which event all Losses so due in excess of the Deductible shall be paid in full by Purchaser and/or Trinity; provided, that the aggregate amount payable by Purchaser and Trinity for all claims arising under this Agreement shall not exceed 33% of the Initial Closing Consideration. Notwithstanding anything to the contrary contained in this Agreement, neither Purchaser nor Trinity shall be required to indemnify any Newpark

Indemnified Party with respect to any Loss (or series of related Losses) incurred by or asserted by reason of any breach of any representation or warranty contained in this Agreement if the Loss (or series of related Losses) from such breach is less than the Minimum Claim Amount, nor shall any Losses less than the Minimum Claim Amount be included for purposes of calculating whether the Deductible has been exceeded. The limitations set forth in this Section 10.5(b) shall not apply with respect to (i) any amounts payable under Section 2.4, Section 2.5 or Losses arising under Section 10.3(b) or Section 10.3(c), and/or (ii) any acts of willful misconduct or fraud.

     10.6 Disregard of Materiality. For purpose of this Article X, all qualifications and exceptions in Article III or Article IV of this Agreement relating to materiality or words of similar impact (including “Material Adverse Effect”) or substantiality or any qualification or requirement that a matter be or not be “reasonably expected to occur” shall be disregarded for purposes of determining whether there has been a breach or inaccuracy of any such representation or warranty pursuant to Section 10.2(a) or Section 10.3(a).

     10.7 Mitigation; Additional Indemnification Provisions. Each Indemnified Party shall use commercially reasonable efforts to mitigate any claim or liability that an Indemnified Party asserts under this Article X. For purposes of this Agreement, Losses shall be decreased by any actually realized Tax Benefit resulting from the payment or accrual of such Losses; provided, however, that Tax Benefits shall only be taken into account for such purpose to the extent that they are actually realized within three (3) years of the Closing Date. For purposes of this Agreement, Losses shall be calculated after giving effect to any amounts recovered from third parties, including amounts recovered under insurance policies with respect to such Losses, net of any costs to recover such amounts. Any Indemnified Party having a claim under these indemnification provisions shall make a good-faith effort to recover all losses, costs, damages and expenses from insurers of such Indemnified Party under applicable insurance policies so as to reduce the amount of any Losses hereunder; provided, that actual recovery of any insurance shall not be a condition to the Indemnifying Party’s obligation to make indemnification payments to the Indemnified Party in accordance with the terms of this Agreement. If the Indemnifying Party receives any amounts under applicable insurance policies, or from any other Person alleged to be responsible for a Loss, after an indemnification payment by the Indemnifying Party has been made for such Loss, then the Indemnified Party shall promptly reimburse the Indemnifying Party for such indemnification payment up to the amount so received or realized by the Indemnified Party. No Indemnified Party will, in any event, be entitled to any incidental, indirect, consequential, special, exemplary or punitive damages (other than any such damages payable to third parties or in the event of fraud, willful misconduct, or Newpark’s breach of Section 5.12). The Indemnifying Party shall not be liable under Section 10.2 for any Loss relating to any matter to the extent that the amount of such Loss is reflected in the calculation of the Closing Date Net Working Capital.

     10.8 Exclusive Remedies. Excluding any claim for injunctive relief or equitable relief relating to any breach of Section 5.12 or as otherwise expressly provided herein, the parties hereto acknowledge and agree that, following the Closing, the indemnification provisions of Sections 10.2 and 10.3 shall be the sole and exclusive remedies of the parties hereto (other than in the case of fraud or willful misconduct), respectively, for any Losses arising out of this Agreement or the transactions contemplated hereby.

     10.9 Tax Indemnification Matters. Notwithstanding anything to the contrary in this Article X, the above provisions of this Article X shall not apply to tax indemnification matters of Sections 7.1(a) and 7.1(b) with respect to the Pre-Closing Period, Straddle Period or Post-Closing Period, which shall instead be governed by Article VII.

ARTICLE XI
