Upon receipt of the Notice of Dispute, the Seller and the Buyer shall promptly consult with each other with respect to the specified points of disagreement in an effort to resolve the dispute. If any such dispute cannot be resolved by the Seller and the Buyer within 30 days after the Buyer receives the Notice of Dispute, the Seller may refer the dispute to the New York Office of Ernst & Young (the “Arbiter”), as an arbitrator to finally resolve, as soon as practicable, and in any event within 45 days after such reference, all points of disagreement with respect to the Closing Adjustment reflected on the Closing Adjustment Statement, the Inventory Report and/or the Accounts Receivable Report. If the Seller does not refer the dispute to the Arbiter within 15 days after the expiration of such 30-day period, ESCO and the Seller shall be deemed to have accepted the Closing Adjustment, the Inventory Report and/or the Accounts Receivable Report, as the case may be, as determined by the Buyer. For purposes of such arbitration each of the Seller and the Buyer shall submit a proposed calculation of the Closing Adjustment, the Inventory Report and/or the Accounts Receivable Report, as the case may be, as of the Effective Time and such proposed calculations shall be consistent with the initial calculations set forth in the Buyer’s Closing Adjustment Statement, the Inventory Report and/or the Accounts Receivable Report and the Seller’s Notice of Dispute. The Arbiter shall apply the terms of Sections 2.4 and 2.5, and shall otherwise conduct the arbitration under such procedures as the Parties may agree or, failing such agreement, under the then prevailing Commercial Rules of the American Arbitration Association. Each of the Parties shall bear its own expenses, including but not limited to the fees and expenses of legal counsel and accountants, in connection with such arbitration. The fees and expenses of the Arbiter incurred in connection with such arbitration shall be allocated equally between the Seller and the Buyer. All determinations by the Arbiter shall be final, conclusive and binding with respect to the Closing Adjustment, the Inventory Report and/or the Accounts Receivable Report and the allocation of arbitration fees and expenses, in the absence of fraud or manifest error.

(c) The Purchase Price shall be adjusted as follows, based on the Closing Adjustment determined pursuant to this Section 2.5: the Seller shall pay to the Buyer the amount by which such Closing Adjustment is less than the Estimated Closing Adjustment and the Buyer shall pay to the Seller the amount by which such Closing Adjustment is greater than the Estimated Closing Adjustment. Any payment so required to be made under this Section 2.5(c) by the Seller shall be by wire transfer of immediately available funds, not more than five Business Days after the earliest of (i) the Seller failing to deliver a Notice of Dispute in a timely fashion, (ii) the Seller failing to refer the dispute to the Arbiter in a timely fashion, and (iii) the Arbiter making a final determination of the dispute, to an account to be designated by the payee at least two Business Days prior to the due date. In the event, but only in the event, the party owing payment hereunder fails to pay the adjustment amount within the time period provided, interest shall be compounded annually, calculated using a 365-day year from the Closing Date through one day prior to the date of payment at an annual rate of five and one-half percent (5¹/2%).

2.6Taxes.

(a) All transfer, documentary, sales, use, value-added, gross receipts, stamp, registration or other similar transfer Taxes incurred in connection with the purchase and sale of Shares and the elections contemplated in Section 2.6(g), including all recording or filing fees, notarial fees and other similar costs of Closing, that may be imposed, payable, collectible or incurred shall be borne 50% by the Buyer and 50% by the Seller.

(b) The Seller shall pay all Pre-Closing Period Taxes unless such Taxes were: (i) accrued as a liability or a reduction in an asset on the Closing Balance Sheet and taken into account in the Closing Adjustment; or (ii) paid prior to Closing by or on behalf of the Transferred Subsidiaries. The Buyer will pay for all Post-Closing Periods Taxes and those Taxes provided for in Section 2.6(a).

(c) The Seller shall prepare, or cause to be prepared, and file, or cause to be filed, all Income Tax Returns for the Transferred Subsidiaries for all periods ending as of or prior to the Closing Date filed after the Closing Date, including without limitation, any amended Income Tax Returns. The Buyer shall not prepare any amended Income Tax Returns with respect to any Transferred Subsidiary for any such periods or any other Pre-Closing Period. In the event that any such Tax Returns are required by Law to be amended, Seller shall prepare and file such Tax Returns. If Buyer believes such Tax Returns are required by Law to be amended and Seller disagrees, the Parties shall submit the issue of whether such amendment is required by Law to the Arbiter, who shall decide the question in the manner prescribed in Section 2.5(b). To the extent that the Arbiter decides the matter in the favor of the Seller, then Seller shall continue to have obligations for indemnification for such Taxes under Section 9.1(d) for the applicable survival period for such indemnification. The Buyer shall cooperate with the Seller in filing and causing to be filed all such Income Tax Returns. The Buyer shall prepare, or cause to be prepared, and file, or cause to be filed, all other Tax Returns for the Transferred Subsidiaries for any taxable period ending as of or prior to the Effective Time that are filed after the Closing Date. All non-Income Tax Returns not yet filed as of Closing shall be filed in a manner consistent with prior practices, policies and Tax Returns of the Seller and such applicable Transferred Subsidiary.

(d) The Buyer shall prepare, or cause to be prepared, and file, or cause to be filed, all Tax Returns for any Straddle Period that are due after the Closing Date. The Buyer shall submit such Straddle Period Income Tax Returns to the Seller for its review and comments at least ten days prior to the due date for filing such Income Tax Returns, and Buyer and the Seller agree to consult and resolve in good faith any issues arising as a result of the review of such Income Tax Returns. The Seller shall pay to the Buyer within 15 days after the date on which Taxes are paid with respect to a Straddle Period an amount equal to the portion of such Taxes that relates to the Pre-Closing Period, reduced by the amount of such Taxes reflected on the Closing Balance Sheet or paid by or on behalf of the Transferred Subsidiaries prior to Closing. For purposes of this Section 2.6(d), the portion of such Tax that relates to the Pre-Closing Period shall (i) in the case of any Income Taxes or Taxes based upon or related to employment, sales and use, value added and other non-periodic Taxes be deemed equal to the amount that would be payable if the relevant Tax period ended as of the Effective Time and (ii) in the case of any periodic Taxes and Taxes other than Taxes described in (i) above be deemed to

be the amount of such Tax for the entire Tax period multiplied by a fraction the numerator of which is the number of days in the Tax period ending as of the Effective Time and the denominator of which is the number of days in the entire Tax period. All determinations necessary to give effect to the foregoing allocations shall be made in a manner consistent with prior practices, policies and Tax Returns of the Seller and such applicable Transferred Subsidiary, unless such prior practices and policies are not in compliance with Tax Law.

(e) Any Tax refunds and interest thereon that are received by the Buyer or the Transferred Subsidiaries (or the Affiliates of any of them), and any amounts credited against Tax to which the Buyer or the Transferred Subsidiaries (or the Affiliates of any of them) become entitled, that relate to Pre-Closing Periods shall be for the account of the Seller, and the Buyer shall pay over to the Seller any such refund and interest or the amount of any such credit within 15 days after receipt or entitlement thereto unless such refund or credit was reflected as an asset or reduction in liability on the Closing Balance Sheet and taken into account in the computation of Closing Adjustment. In the event the Buyer fails to pay the Seller any such amounts due under this Section 2.6(e) within the time period specified, Buyer shall pay, in addition to the amounts due, interest on such amount, compounded annually, calculated using a 365 day year from the date of receipt or entitlement thereto through the date prior to the date of payment at a rate of five and one-half percent (5¹/2%).

(f) The Buyer and the Seller agree to furnish, or cause to be furnished, to each other, upon written notice pursuant to Section 10.1, as promptly as practical, such information (including reasonable access to books and records) and assistance as is reasonably necessary for the filing of any Tax Return, preparation of the portion of any financial statement related to Taxes, the conduct of any Tax audit, and for the prosecution or defense of any claim, suit or proceeding relating to any Tax matter. The Buyer and the Seller shall reasonably cooperate with each other in the conduct of any Tax audit or other Tax proceedings and each shall execute and deliver such documents as are reasonably necessary to carry out the intent of this Section 2.6(f). Any Tax audit or other Tax proceeding shall be deemed to be a third party claim subject to the procedures set forth in Section 9.4 of this Agreement. In the event of a Tax audit that is a Third Person Claim that solely relates to any Transferred Subsidiary for a Pre-Closing Period controlled by Seller or ESCO under Section 9.4, Seller and ESCO shall keep Buyer reasonably informed regarding the progress of any item related to such claim. In the event that Buyer reasonably believes the resolution of such claim would result in an increase in the Tax liability of any of the Transferred Subsidiaries or Buyer for Post-Closing Period for which Seller or ESCO is not obligated to indemnify Buyer or the Transferred Subsidiaries under Section 9.1, Seller may not resolve the issue in such manner unless Buyer consents, and such Buyer consent may not be unreasonably withheld or delayed. In the event that Buyer does not consent to such resolution, the Parties shall submit the issue of whether such resolution is a reasonable (as considered against the impact to Buyer and Seller) manner for the claim to be resolved to the Arbiter, who shall decide the question in the manner prescribed in Section 2.5(b). In the event that the Arbiter determines that the proposed resolution is reasonable (as considered against the impact to Buyer and Seller), at Buyer’s election, (i) Buyer may resume control of such claim provided that Buyer waives any right to indemnification under Section 9.1 and Buyer agrees to indemnify ESCO and Seller against any additional Taxes incurred by either of them as a direct result of the resolution of such claim by Buyer; or (ii) Seller may resolve the claim in the manner presented to the Arbiter.

(g) At Closing, the Seller and Buyer shall join in making an election under Section 338(h)(10) of the Code with respect to both: (i) the purchase and sale of the Shares and (ii) any of the Transferred Subsidiaries organized in the United States, including any corresponding election under state and local Tax Law (a “338 Election”), and the Buyer may elect, at its own discretion (Buyer agrees to make good faith efforts towards reaching its decision within 120 days of Closing on whether to make an election, and in any event to keep Seller reasonably apprised of its progress on the decision-making process), to make an election under Section 338(g) with respect to any Transferred Subsidiary that is organized outside of the United States. The Parties will timely file such forms with the IRS, state and local Taxing authority as may be required with their respective Tax Returns for the periods that include the Closing Date and otherwise to make effective the 338 Election. The Purchase Price shall be allocated among the acquired assets and shares in accordance with the Internal Revenue Code and Treasury Regulations promulgated thereunder after the Closing. In connection with the determination of the foregoing allocation, the parties shall cooperate with each other and provide such information as any of them shall reasonably request. Failing agreement, the Parties may file such Tax Returns as they believe, in good faith, are appropriate.

(h) Buyer will file IRS Form 8023 effecting the 338 Election within five Business Days after Closing and promptly thereafter provide Seller with a copy of such filing and certified proof of mailing.

5.1General Obligations.

(a) In regard to the Closing (i) where applicable law or rules provide for the automatic transfer of employment of the Employees upon the sale of the Business, (A) the Buyer or one of its Affiliates shall assume and honor all terms and conditions of employment in respect of the Employees to the extent required to accomplish such transfer of employment, (B) the Buyer and ESCO agree to take such actions as are reasonably practicable such that the employment of the Employees (other than the Excluded Employees) will transfer to the Buyer or its Affiliate as a matter of law as of the Effective Time, and (C) the Buyer or one of its Affiliates shall employ each Employee at the same salary and wages payable by ESCO or its Affiliates to such Employee immediately prior to the Effective Time and, as and to the extent required by Law, shall maintain terms and conditions of employment which replicate those provided by ESCO or its Affiliates immediately prior to the Effective Time (but in the United States hired “at will” and nothing in this Agreement changes Buyer’s right to terminate any employee at any time after the Closing), and (ii) where applicable Law or rules do not provide for the automatic transfer of employment of the Employees upon the sale of the Business, the Buyer or one of its Affiliates shall make an offer of employment, to be effective as of the Effective Time, to such Employees at the same salary, wages (and, to the extent required to avoid, if possible, under applicable Law or rules, statutory and other severance obligations and other termination obligations arising solely out of the transactions contemplated by this Agreement and the consequent transfers of employment, any such other forms and amounts of compensation and benefits) and terms and conditions of employment provided by ESCO or its Affiliates to such Employees immediately prior to the Effective Time.

(b) The Buyer and ESCO shall use commercially reasonable efforts to take any and all required actions necessary to minimize to the greatest extent practicable the possibility that severance benefits and/or government-required, statutory or common law termination liabilities shall be payable to an Employee regardless of whether such Employee becomes employed by the Buyer or one of its Affiliates.

(c) If, upon the consummation of the transactions contemplated by the Agreement, the payment of stock compensation is due to any Employee or the payment of severance benefits and/or government-required, statutory or common law termination liabilities is due to any Employee, and such payment has been triggered automatically upon a change of control of the Transferred Subsidiaries, notwithstanding the nature and circumstances of the Buyer and the parties’ compliance with the provisions of Section 5.1(b), then such payments and/or liabilities shall be the sole responsibility of ESCO and ESCO shall indemnify the Buyer and its Affiliates and hold them harmless from and against any such payments or liabilities which may be incurred or suffered by any of them in connection with any claim made by an Employee on such grounds on or after the Effective Time. If any Employee exercises a nonqualified stock option between the Closing Date and December 31, 2007, then Seller shall prepare a Form W-2 or 1099 for such Employee reflecting such exercise, and Seller shall withhold any Taxes required by Law to be withheld and Seller shall remit such amount to the appropriate Tax authority. If any Employee exercises an incentive stock option after Closing

Date and prior to December 31, 2007, and effects a same day sale through ESCO, then Seller shall prepare a Form W-2 or 1099 for each such Employee appropriately reflecting such same day sale. Buyer and Seller agree any deduction with respect to the exercise of a nonqualified stock option or a disqualified disposition of stock received from the exercise of an incentive stock option may only be claimed by Seller.

(d) If, upon the consummation of the transactions contemplated by the Agreement, the payment of stock compensation is due to any Employee or the payment of severance benefits and/or government-required, statutory or common law termination liabilities is due to any Employee, and such payment and/or liability is triggered other than for reasons described in Section 5.1(c) above, then such payments and/or liabilities shall be the sole responsibility of the Buyer and the Buyer shall indemnify ESCO and its Affiliates and hold them harmless from and against any Losses which may be incurred or suffered by any of them in connection with any claim made by an Employee for such grounds on or after the Effective Time.

(e) The Buyer shall credit (or cause to be credited) service accrued by Transferred Employees as of the Effective Time for all purposes under its Benefit Plans.

(f) At the Effective Time, (i) the non-U.S. Transferred Employees (as defined below) shall cease to participate in the welfare benefit plans of ESCO and the Seller, and (ii) the U.S. Transferred Employees (as defined below) shall cease to participate in the welfare benefit plans of ESCO and the Seller;provided,however, that the medical plan for Filtertek-U.S. shall be continued as a multiple employer plan through January 31, 2008 at which time the U.S. Transferred Employees shall cease to participate in such plan. The Buyer shall be responsible for any and all premiums and other fees and expenses associated with the participation of Filtertek-U.S. in such medical plan.

(g) At the Effective Time, the Buyer will provide to Transferred Employees a continuation of welfare benefits, under welfare benefits plans maintained by the Buyer, one of its Affiliates or the Transferred Subsidiaries on and after the Effective Time, that, for all jurisdictions where it is required by Law, are substantially comparable to those in effect for Transferred Employees at the time of the Closing. Each Transferred Employee shall be immediately eligible to participate, without any waiting time, in such welfare benefit plans of the Buyer or one of its Affiliates made available to such Transferred Employees (to the extent that coverage replaces coverage under a comparable welfare benefit plan of ESCO, in which such Transferred Employee participated immediately prior to the Effective Time). For purposes of each welfare benefit plan of the Buyer or one of its Affiliates providing medical, dentaland/or pharmaceutical benefits to any Transferred Employee, the Buyer shall cause all pre-existing condition exclusions and actively-at-work requirements of such plans (other than employee basic life, employee basic AD&D, optional employee life, optional employee AD&D and basic and optional dependent life) to be waived for such Transferred Employee and his or her covered dependents (other than limitations or waiting periods that are already in effect with respect to such Employees and dependents and that have not been satisfied as of the Effective Time).

At a point after the Closing Date, which such date shall be determined by the Buyer but shall not be later than January 1, 2008, the Buyer or one of its Affiliates shall have in effect one or more Defined Contribution Plans that include a qualified cash or deferred arrangement within the meaning of Section 401(k) of the Code (“Buyer’s 401(k) Plan”).

The Buyer shall be responsible for any and all premiums and other fees and expenses associated with, and shall process, all dental, life insurance and long-term disability benefit coverage claims by U.S. Transferred Employees on and after the Effective Time for claims incurred by such U.S. Transferred Employees under group dental, life, travel, disability accident, and accidental death and dismemberment insurance policies in which U.S. Transferred Employees are or become eligible.

(c) Without limiting the remedies available, the parties to this Agreement agree that damages at law may be an insufficient remedy in the event of breach of this Section 6.4 and that the injured party should be entitled to seek injunctive relief or other equitable remedies in the event of any such breach.

(d) If any of the provisions of this Section 6.4 are held to be unenforceable in any jurisdiction, then, as to such jurisdiction, such provision shall be ineffective to the extent of its unenforceability in such jurisdiction, without affecting the remaining provisions of this Section in such jurisdiction, or affecting in any other jurisdiction the validity or enforceability of such provision or of this Section.

(a) The Buyer acknowledges that (i) the coverage of each Transferred Subsidiary for incidents which arise after the Effective Time under all of the insurance policies maintained by ESCO or its Affiliates (other than the Transferred Subsidiary Policies) immediately prior to the Effective Time, will be terminated as of the Effective Time applicable to the Transferred Subsidiaries, and (ii) upon such termination, the Transferred Subsidiaries will cease to be covered under such policies with respect to the period after the Effective Time and will have to obtain replacement coverage for such period.

(b) After the Closing, ESCO shall provide reasonable assistance to the Buyer and the Transferred Subsidiaries with respect to any Losses of the Transferred Subsidiaries that arose from events, matters and circumstances which occurred or existed prior to the Effective Time (“Occurences”) and are reasonably likely to be covered by the Applicable ESCO Insurance. For purposes of this Section 6.5, reasonable assistance may include, without limitation, making claims on behalf of the Buyer, at the Buyer’s request, under the Applicable ESCO Insurance;provided,however, that the foregoing shall not be deemed to cause ESCO or its Affiliates to be liable for the payment of any deductible applicable to any such claim as a result of this Section 6.5. The foregoing shall not limit Buyer’s right of recovery for such deductible under some other provision herein. Buyer shall have all rights to make claims directly under the Applicable ESCO Insurance for Occurrences.

The Buyer agrees to be responsible for all bills received by ESCO or the Seller subsequent to the Closing Date but prior to the Cut-Off Date, incurred in the ordinary course of the Business that directly relate to the operations of such Transferred Subsidiaries such as bills for goods or services, including but not limited to legal fees (excluding legal fees related in any manner to the negotiation of this Agreement or the documents contemplated hereby or to the consummation of the transactions contemplated hereby), patent-related costs and expenses for services such as insurance coverage;provided,however, that neither the Buyer nor the Transferred Subsidiaries will be responsible (a) for bills related in any manner to the negotiation of this Agreement or the documents contemplated hereby or to the consummation of the transactions contemplated hereby or (b) for bills if and to the extent that such billed amounts are not reflected as liabilities or a reduction in assets on the Closing Balance Sheet. The Seller shall provide the Buyer with a copy of all such bills in respect of this Section 6.7. For purposes of this Section 6.7, “Cut-Off Date” shall mean the date which is three months after the Closing Date. To the extent wages for Transferred Employees and associated withholdings, including without limitation withholdings for benefits and taxes, are due and payable following the Closing Date but are attributable to periods prior to the Closing Date, the Buyer shall be responsible for payment of all such wages and for payment and remittance of all withholdings.

6.8Guarantees. The Buyer will cooperate and use its best efforts to obtain a full and unconditional release of all ESCO Guarantees, including by agreeing to enter into a reasonable replacement guarantee in favor of any third party creditor who is a beneficiary of such ESCO Guarantee;provided,however, that the Buyer may elect not to obtain such a release of any ESCO Guarantee which, by its terms, terminates less than one year after the Closing Date. “ESCO Guarantee” means any guarantee, indemnity, performance bond, letter of credit (and any related contract), deposit or other security or contingent obligation in the nature of a financial obligation including letters of comfort or support entered into or granted by ESCO or any of its Affiliates (other than the Transferred Subsidiaries) in relation to or arising out of any obligations or liabilities of the Transferred Subsidiaries set forth inDisclosure Schedule 6.8. The Buyer will indemnify and hold ESCO harmless for any and all Losses arising after the Effective Time in connection with any ESCO Guarantee that is not replaced with a reasonable replacement guarantee from Buyer as reference above.

6.9Voluntary Reporting(a) .

(a) For a period of two years after the Closing Date, neither Buyer nor the Transferred Subsidiaries nor any of their Affiliates shall “voluntarily” report (as defined below in this Section 6.9(a)) any possible violation of Law relating to the Business or the Transferred Subsidiaries without the prior written consent of ESCO. A report is deemed “voluntarily” made in all cases where Buyer or any Affiliate of Buyer, directly or indirectly, reports a violation of Law relating to the Business or the Transferred Subsidiaries except in those cases where such disclosure is expressly mandated by applicable Law and Buyer’s counsel provides notice in the form set forth in Exhibit B. To the extent feasible and where such would not create additional material liability, Buyer shall provide ESCO advance notice of any voluntary disclosure in the form set forth in Exhibit B. After two years after the Closing Date, the Buyer, any of the Transferred Subsidiaries or any of their Affiliates may voluntarily report any possible violation of Law relating to the Business or the Transferred Subsidiaries provided that Buyer, a Transferred Subsidiary or one of their Affiliates notifies and consults with ESCO regarding the matter proposed to be reported at least seven days in advance of any such reporting.

(b) No later than the close of business on the second Business Day following the Closing Date, Seller will prepare and submit on behalf of Filtertek-U.S. a voluntary disclosure to US Customs of all US import duty and classification violations, which were prepared after due consideration of the KPMG report provided by Buyer. Seller will deliver a copy of the disclosure to Buyer prior to submission to US Customs and will consider in good faith all such modifications to the disclosure or any subsequent filing with U.S. Customs, if any, as are suggested by Buyer. Buyer and the Transferred Subsidiaries will cooperate with Seller in the investigation and preparation of this disclosure, including delivery to Seller on the Closing Date of the KPMG report resulting from the recent audit conducted by them of these issues. Seller shall keep Buyer adequately informed about the disclosures to the U.S. Customs until final resolution. Buyer will cooperate to provide Seller such authorization as is necessary for Seller to make such disclosure and defend such proceedings.

(c) For a period of two years after the Closing Date, neither Seller nor any of their Affiliates shall “voluntarily” report (as defined below in this Section 6.9(c)) any possible violation of Law relating to the Business or the Transferred Subsidiaries without the prior written consent of Buyer, other than with respect to violations of Tax Law (which such matters are addressed in Section 2.6). A report is deemed “voluntarily” made in all cases where Seller or any Affiliate of Seller, directly or indirectly, reports a violation of Law relating to the Business or the Transferred Subsidiaries except in those cases where such disclosure is expressly mandated by applicable Law and Seller’s counsel provides notice in the form set forth in Exhibit B. To the extent feasible and where such would not create additional material liability, Seller shall provide Buyer advance notice of any voluntary disclosure. After two years after the Closing Date, the Seller or any of their Affiliates may voluntarily report any possible violation of Law relating to the Business or the Transferred Subsidiaries provided that Seller or one of their Affiliates notifies and consults with Buyer regarding the matter proposed to be reported at least seven days in advance of any such reporting.

6.10Inventory and Accounts Receivable.

(a) Within thirty days after the first anniversary of the Closing Date, the Buyer shall cause the Transferred Subsidiaries to prepare and provide to ESCO a complete and

detailed list of the inventory of the Transferred Subsidiaries taken from the books and records of the Transferred Subsidiaries as of such first anniversary, listed by inventory item, item quantity and item value in U.S. Dollars and prepared consistently with the Inventory Report (the “One Year Inventory Report”). If any inventory item has experienced five percent turnover or less during such one year period (“Slow Moving Inventory”) and the entire item value, along with any other Slow Moving Inventory, exceeds the inventory reserve reflected on the Closing Balance Sheet, then, at the election of the Buyer made in the One Year Inventory Report, the amount of such excess shall be deemed to be subtracted from the Capital Employed reflected on the Closing Balance Sheet (the “Inventory Adjustment”).

(b) Within thirty days after the first anniversary of the Closing Date, the Buyer shall cause the Transferred Subsidiaries to prepare and provide to ESCO a complete and detailed list of the accounts receivable of the Transferred Subsidiaries that, as of such first anniversary, are one year old or older taken from the books and records of the Transferred Subsidiaries (“Aged Receivables”), listed by account number, counterparty and value in U.S. Dollar and prepared consistently with the Accounts Receivable Report (the “One Year Accounts Receivable Report”). If the entire value of the Aged Receivable (if any) exceeds the reserve reflected on the Closing Balance Sheet, then, at the election of the Buyer made in the One Year Accounts Receivable Report, the amount of such excess shall be deemed to be subtracted from the Capital Employed reflected on the Closing Balance Sheet (the “Accounts Receivable Adjustment”).

(c) The Buyer shall permit ESCO to review, consistent with the terms of Section 2.5(a), the records necessary to evaluate the reports prepared pursuant to Section 6.10(a) and (b) and ESCO may dispute such reports consistent with the terms of Section 2.5(b).

(d) If the inclusion of the Inventory Adjustment and the Accounts Receivable Adjustment would have decreased the Closing Adjustment paid by the Buyer to the Sellers or increased the Closing Adjustment paid by the Sellers to the Buyer, as the case may be, then the Sellers shall pay to the Buyer the amount of such change to the Closing Adjustment and the Buyer shall transfer, or cause to be transferred, to the Sellers all right, title and interest in the Slow Moving Inventory and the Aged Receivables and shall provide the Sellers with all reasonably requested assistance to dispose of such inventory and collect such receivables.

6.11Claims. ESCO agrees that it shall retain the defense of, and the settlement of, all claims or liabilities (including any costs or expenses) related to the Anthony M. McCauley Claim and the Theresa Gibson Claim and may settle such claim if (a) such settlement involves only the payment of money and does not involve an admission of fault or (b) it receives the Buyer’s consent, which consent shall not be unreasonably withheld.

6.12Supply Agreements.

(a) For a period of not less than one year after the Closing Date, the Transferred Subsidiaries shall provide Distribution Control Systems Inc. and Hexagram, Inc., and provide to their third party contract manufacturers to the extent of any requirements for fulfillment of contracts with Distribution Control Systems Inc. and Hexagram, Inc., with such products as the Transferred Subsidiaries have historically provided to such entities or which are

available generally from the Transferred Subsidiaries for use in new products now planned by such entities (the “Filtertek Transferred Subsidiary Products”). The Filtertek Transferred Subsidiary Products shall be sold at prices in effect on the Closing Date, which in all circumstances shall remain fixed for one year after the Closing Date, and subject to the non-price related standard terms and conditions the Transferred Subsidiaries provide to other comparable customers.

(b) For a period of not less than one year after the Closing Date, VACCO Industries shall provide the Transferred Subsidiaries with such products as VACCO has historically provided to such entities or which are available generally from the Transferred Subsidiaries for use in new products now planned by such entities (the “VACCO Transferred Subsidiary Products”). The VACCO Transferred Subsidiary Products shall be sold at prices in effect on the Closing Date, which in all circumstances shall remain fixed for one year after the Closing Date, and subject to the non-price related standard terms and conditions VACCO provides to other comparable customers.

6.13Assignment of Maquiladora Agreement. As soon as practical after the Closing Date and upon Buyer’s request, Seller will use commercially reasonable efforts to assign to Fitertek-U.S., or to another appropriate Transferred Subsidiary, the Maquiladora agreement, if such assignment can be effected under applicable Law and if it can be reasonably accomplished in a manner which results in Seller have no continuing liability or obligation beyond the date of such assignment.

6.14Use of Seller Agreements. To the extent allowed under the agreements with the respective third parties, Seller agrees to allow the Transferred Subsidiaries and their employees for 15 days post closing to continue to make charges under Seller’s freight, car rental, travel, credit card, cell phone, and calling card programs in the manner conducted prior to Closing. In return Buyer agrees to pay for all of such charges arising out of Buyer’s or its employees’ use during this 15 day period and to promptly make payments of the same to Seller upon its submission of an appropriate invoice to Buyer.

(c) any and all liabilities and obligations of any nature whatsoever related to ESCO’s use of the Closing Financial Statements in any public filing, provided that Buyer complied with its obligations under Section 2.4;

(d) Taxes of the Transferred Subsidiaries for all Pre-Closing Periods, except to the extent Taxes are reflected as a liability or a reduction of an asset on the Closing Balance Sheet and taken into account in the Closing Adjustment or paid prior to Closing. For the avoidance of doubt, this shall include any Tax liabilities for all Pre-Closing Periods arising under any indemnification or guarantee obligations set forth in customer Contracts, regardless of any disclosure hereunder;

(e) any and all liabilities or costs arising out of the Anthony M. McCauley Claim;

No. EP-B-629418 and any costs of proceedings related to such reimbursement claims, including all related attorneys fees (and Seller shall control any related proceedings and will cooperate with Buyer in the conduct of all aspects of the same to the extent these contain issues which Buyer reasonably has asserted will impact future royalties or the defense of such patents including any foreign or priority counterparts);

(h) any and all liabilities (including all related attorney fees) or claims relating to the defense of import duties and classifications arising from the voluntary disclosure made on behalf of Filtertek-U.S. as provided in Section 6.9(b) (and, notwithstanding Section 9.4, Seller shall have full control of the defense of all such related proceedings);

(j) any and all liabilities related to the back flow issues with the check valves at Cardinal Health, as more further described in Disclosure Schedule 3.5, to the extent in excess of the respective warranty accrual on the Closing Balance Sheet but such accrual not to exceed fifty thousand dollars ($50,000) (notwithstanding Section 9.4, all consents to judgment or settlements of this issue must first be approved by Seller, such consent to not be unreasonably withheld).

Any indemnification provided for under this Section 9.1 shall be deemed to last for a period of: (i) 18 months from the Closing Date for 9.1(a), (b) or (j), unless otherwise set

forth to the contrary in Section 9.5; (ii) indefinitely for 9.1(c), (e) (f) and (i); (iii) the expiration of the statute of limitations plus three months for 6.3, 6.4, 6.5, 6.6, 6.9 and 9.1(d); five years from the Closing Date for 9.1(g) and (h), and (iv) deemed also to extend to directors, shareholders, officers and employees (in their capacity as such) of the Buyer and, following the Closing, of the Transferred Subsidiaries, and their Affiliates (in all, the “Buyer Indemnified Persons”). Further, for and to the extent that a claim for indemnification is the subject of a Notice of Claim provided to the Indemnifying Party within the applicable survival period for such indemnification, the Injured Party shall be entitled to continued indemnification for such claim until such claim is resolved.

9.2Indemnification by the Buyer. Subject to the limitations set forth in this ARTICLE IX, the Buyer shall indemnify, defend and hold harmless ESCO against and in respect of any and all Losses incurred directly or indirectly in connection with, arising from or as a result of:

(a) any breach, non-fulfillment or violation of the covenants or agreements made in this Agreement by the Buyer or any of their Affiliates, including, following Closing, the Transferred Subsidiaries;

(c) the ownership of the Shares, or the Transferred Subsidiaries, or the conduct or operation of the Business after the Effective Time (except, in each such case, to the extent that the Buyer is entitled to be indemnified pursuant to Section 9.1);

(d) any severance benefits or termination liabilities of Buyer arising in connection with the transactions contemplated hereby to the extent provided for in Sections 5.1(b) and 5.3(b); and

(e) any and all liabilities of ESCO or Seller arising out of the matters described inDisclosure Schedule 9.2(e).

Any indemnification provided for under this Section 9.2 shall be: (i) deemed to last for a period of 18 months except with respect to 9.2(a) in regard to claims under Sections 6.1, 6.6, 6.8 and 6.9, the expiration of the statute of limitations plus three months, and except with respect to 9.2(e), in which case for five years from the Closing Date, and in all these cases unless otherwise set forth to the contrary in Section 9.5, and (ii) deemed also to extend to directors, shareholders, officers and employees (in their capacity as such) of ESCO, and its Affiliates other than the Transferred Subsidiaries (in all, the “Seller Indemnified Persons”). Further, for and to the extent that a claim for indemnification is the subject of a Notice of Claim provided to the Indemnifying Party within the applicable survival period for such indemnification, the Injured Party shall be entitled to continued indemnification for such claim until such claim is resolved.

9.3Notice and Payment of Losses. Upon obtaining knowledge of any Loss, any Person entitled to indemnification under Section 9.1 or Section 9.2 (the “Injured Party”) shall give written notice to the Party liable for such indemnification (the “Indemnifying Party”) specifying the facts constituting the basis for such claim and the amount, to the extent known, of the claim asserted (such written notice being hereinafter referred to as a “Notice of Claim”). The Injured Party shall use commercially reasonable efforts to mitigate any Loss (including without limitation by using commercially reasonable efforts to obtain any applicable insurance proceeds) and to obtain or use any Tax savings, benefit, relief, deduction or credit available to the Injured Party. If the Indemnifying Party disputes such claim of indemnification, it shall notify the Injured Party thereof within 30��days after receipt of the Notice of Claim, whereupon the Parties shall meet and attempt in good faith to resolve their differences with respect to such claim or indemnification. If the dispute has not been resolved within 30 days after the parties first meet to attempt such resolution, and after satisfaction of ARTICLE XI, either party may initiate litigation in accordance with this Agreement. If the Indemnifying Party does not dispute the Injured Party’s claim of indemnification, the Indemnifying Party shall pay the amount of any valid claim within 30 days after receipt of the Injured Party’s Notice of Claim.

9.4Defense of Third Person Claims. If an Injured Party is entitled to indemnification hereunder because of a claim asserted by any claimant (other than an indemnified Person hereunder) (“Third Person”), the Injured Party shall give a Notice of Claim to the Indemnifying Party within 30 days after such assertion is actually known to the Injured Party by written notice;provided,however, that the right of a Person to be indemnified hereunder in respect of claims made by a Third Person shall not be adversely affected by a failure to give such Notice of Claim unless, and then only to the extent that, an Indemnifying Party is prejudiced thereby. The Indemnifying Party shall have the right, upon written notice to the Injured Party, and using counsel reasonably satisfactory to the Injured Party, to investigate, secure, contest, or settle the claim alleged by such Third Person (a “Third Person Claim”) provided that the Indemnifying Party notified the Injured Party in writing of its election to indemnify the Injured Party with respect to such Third Person Claim; and provided further that the Indemnifying Party will not consent to the entry of any judgment with respect to the matter or enter into any settlement with respect to the matter without the written consent of the Injured Party (not to be withheld or delayed unreasonably) except that the Indemnifying Party shall be entitled to consent to any judgment and/or enter into any settlement without the consent of the Injured Party if such judgment or settlement requires only the payment of money (without admitting fault) and effective upon the payment by the Indemnifying Party of all such money due. For the avoidance of doubt, a claim or challenge asserted by a governmental agency, including without limitation the IRS, the U.S. Department of Commerce or the U.S. Treasury Department, against an Injured Party shall be considered a Third Person Claim hereunder. The Injured Party may thereafter participate in (but not control) the defense of any such Third Person Claim with its own counsel at its own expense, except in the event of a conflict of interest, where the Indemnified Party can control and the Indemnifying Party must reimburse. For purposes of clarification, the fact that the Injured Party has sought indemnification from the Indemnified Party shall not be considered in determining whether a conflict of interest exists. If the Indemnifying Party elects not to defend the Injured Party with respect to such Third Person Claim, the Injured Party shall have the right, at its option, to assume and control defense of the

matter. The failure of the Indemnifying Party to respond in writing to the Notice of Claim within 30 days after receipt thereof shall be deemed an election not to defend the same. If the Indemnifying Party does not so acknowledge its obligation to indemnify and assume the defense of any such Third Person Claim, (a) the Injured Party may defend against such claim, in such manner as it may deem appropriate, including, but not limited to, settling such claim, after giving written notice of the same to the Indemnifying Party, on such terms as the Injured Party may deem appropriate; provided that in all cases the Injured Party will not consent to the entry of a judgment or enter into any settlement with respect to the matter without the written consent of the Indemnifying Party (not to be withheld or delayed unreasonably, or if unreasonably withheld, then requiring the Indemnifying Party to immediately take over the defense of such claim, except that the Injured Party shall be entitled to consent to any judgment and/or enter into any settlement without the consent of the Indemnifying Party if such judgment or settlement does not require the payment of money and the Injured Party will not seek indemnification from the Indemnifying Party), and (b) the Indemnifying Party may participate in (but not control) the defense of such action, with its own counsel at its own expense. The Parties shall make available to each other all relevant information in their possession relating to any such Third Person Claim and shall reasonably cooperate in the defense thereof.

9.5Survival of Representations and Warranties. All of the representations and warranties made by any Party in ARTICLE III and ARTICLE IV shall survive for a period of 18 months following the Closing Date and thereafter to the extent a Notice of Claim is made within such period with respect to any breach of such representation or warranty occurring within such period and set out in such Notice of Claim; provided that: (i) the representations and warranties set forth in Sections 3.1(a), 3.2, 3.3(a) and (c), 4.1(a) and 4.2 shall survive the Closing Date for an unlimited duration; (ii) the representations and warranties set forth in Section 3.6 shall survive until the expiration of the statute of limitations applicable to the matters set forth therein plus three months; (iii) the representations and warranties set forth in Section 3.30 shall survive for a period of three years following the Closing Date; and (iv) the representations and warranties set forth in Sections 3.14 and 3.15 shall survive for a period of five years following the Closing Date. No party shall be entitled to indemnification for breach of any representation and warranty set forth in ARTICLE III and ARTICLE IV unless a Notice of Claim of such breach has been given to the Indemnifying Party within the period of survival of such representation and warranty as set forth herein. Further, for and to the extent that a claim for a breach of a representation or warranty is the subject of a Notice of Claim provided to the Indemnifying Party within the applicable survival period for such representation or warranty, the Injured Party shall be entitled to continued indemnification for such claim until such claim is resolved.

actions, inactions, facts or circumstances, such multiple situations shall be aggregated to constitute a single “individual item” for purposes of the preceding clause.

(b) The provisions for indemnity under Section 9.1(b) and Section 9.2(b) shall be effective only when the aggregate amount of all Losses for which indemnification is sought exceeds four hundred twenty-five thousand U.S. Dollars (U.S. $425,000), in which case the Injured Party shall be entitled to indemnification of the Injured Party’s Losses only in excess thereof;provided,however, that the foregoing four hundred twenty-five thousand U.S. Dollars (U.S. $425,000) limitation shall not apply in any manner whatsoever to any breach of a representation or warranty contained in Sections 3.1(a), 3.2, 3.3(a), 3.6, 4.1(a), 4.2, 4.5(a), 6.9 (except to the extent provided therein) or 6.11.

(c) The indemnification obligations of ESCO and the Seller pursuant to Section 9.1 shall be effective only until the dollar amount paid by ESCO and Seller, taken together, in respect of all Losses indemnified against under such Section aggregates eleven million U.S. Dollars (U.S. $11,000,000).

(d) The indemnification obligations of the Buyer pursuant to Section 9.2 shall be effective only until the dollar amount paid by the Buyer in respect of all Losses indemnified against under such Sections aggregates eleven million U.S. Dollars (U.S. $11,000,000).

(e) All indemnification obligations shall be paid in U.S. Dollars in the United States.

(f) Notwithstanding anything in this Agreement to the contrary, no Liability, obligation, contract or other matter shall constitute a breach of any representation or warranty of ESCO or entitle the Buyer Indemnified Persons to indemnification hereunder

(g) to the extent, but only to the extent, of the amount of such Liability, obligation, Contract or other matter was provided for in the Closing Balance Sheet. Each Party hereby agrees that it shall, and it shall cause its Affiliates to, use its or their commercially reasonable efforts to mitigate any Losses to be indemnified under this ARTICLE IX.

(h) All Losses, other than from matters relating to the United States or foreign laws concerning the import or export of goods, for which indemnification is provided pursuant to Section 9.1 shall be deemed to be eighty percent of such Losses, until such time as the twenty percent of such Losses for which the Buyer Indemnified Persons are not indemnified under thisSection 9.6(h) exceed One Hundred Thousand U.S. Dollars (U.S. $100,000), for all purposes under this Agreement if such Losses are incurred directly or indirectly, in connection with, arising from or as a result of the Buyer or the Transferred Subsidiaries or any Affiliate thereof “voluntarily” reporting (as defined in Section 6.9(a)) any possible violation of Law relating to the Business or the Transferred Subsidiaries.

(i) All Losses for which indemnification is provided pursuant to Section 9.2 shall be deemed to be eighty percent of such Losses, until such time as the twenty percent of such Losses for which the Seller Indemnified Persons are not indemnified under thisSection 9.6(h) exceed One Hundred Thousand U.S. Dollars (U.S. $100,000), for all purposes under this Agreement if such Losses are incurred directly or indirectly, in connection with, arising from or

as a result of the Seller or any Affiliate thereof “voluntarily” reporting (as defined in Section 6.9(c)) any possible violation of Law relating to the Business or the Transferred Subsidiaries.

(j) Any liability for indemnification under this ARTICLE IX shall be determined without duplication of recovery by reason of the state of facts giving rise to such liability constituting a breach of more than one representation, warranty, covenant or agreement. Further, no Loss shall be entitled to be indemnified under this ARTICLE IX and the amount of any Loss shall not be included in the calculation of the limitation set forth in Section 9.6(b) or any other limitations on indemnification set forth herein, to the extent that such Loss is included in the calculation of the Closing Adjustment, the Inventory Adjustment, the Accounts Receivable Adjustment or has otherwise been taken into account pursuant to the terms of this Agreement. Similarly, no Loss shall be included in the calculation of the Closing Adjustment, the Inventory Adjustment, the Accounts Receivable Adjustment or has otherwise been taken into account pursuant to the terms of this Agreement to the extent that such Loss is subject to a Notice of Claim or has been indemnified, under this ARTICLE IX.

(b) To the extent permitted by Law, no existing or former director or officer of ESCO or any of the Transferred Subsidiaries, and no current adviser of ESCO or any of the Transferred Subsidiaries advising in its capacity as such in relation to the transactions contemplated by this Agreement will, be liable to Buyer or any of the Transferred Subsidiaries for acts, matters or things that occurred before or at Closing, nor for acts, matters or things occurring after Closing to the extent related to this Agreement or the transactions contemplated by this Agreement, other than an act of fraud by that person.

(c) To the extent permitted by Law, no director, officer, employee, Affiliate (including officers and employees of such Affiliate), agent, adviser, representative or their successors and assigns of Buyer will be liable to ESCO in respect of any act, matter or thing that occurred before, at or after Closing and related to this Agreement or the transactions contemplated by this Agreement, other than an act of fraud by that person.

(d) This Section 9.7 is intended to be for the benefit of, and shall be enforceable by, the Seller Indemnified Persons and the Buyer Indemnified Persons referred to herein, their heirs and personal representatives and shall be binding on Buyer and ESCO and their respective successors and assigns.

10.2Entire Agreement. This Agreement and the Schedules and Exhibits hereto, the Related Agreements and any documents executed by the Parties pursuant to this Agreement embody the entire agreement and understanding of the parties hereto with respect to the subject matter hereof, and supersede all prior and contemporaneous agreements and understandings relating to such subject matter, including the Letter of Intent, dated August 2, 2007 between the Buyer and ESCO, and the Non-disclosure Letter, dated June 26, 2007 between ESCO and the Buyer, which shall terminate and shall be of no further force or effect.

10.3Severability. If any provision hereof shall be held invalid or unenforceable by any court of competent jurisdiction or as a result of future legislative action, such holding or action shall be strictly construed and shall not affect the validity or effect of any other provision hereof, as long as the remaining provisions, taken together, are sufficient to carry out the overall intentions of the Parties as evidenced hereby.

10.4Assignment; Binding Agreement. This Agreement and various rights and obligations arising hereunder shall inure to the benefit of and be binding upon the Parties hereto and their successors and permitted assigns. Neither this Agreement nor any of the rights, interests, or obligations hereunder shall be transferred, delegated, or assigned by the Parties hereto without the prior written consent of the other Party (which consent shall not be unreasonably withheld) except that Buyer may transfer this Agreement to an Affiliate of Buyer without consent, provided any such transfer shall not relieve the Buyer of its obligations hereunder.

10.5Counterparts. This Agreement may be executed simultaneously in multiple counterparts, and in separate counterparts, each of which shall be deemed an original, but all of which taken together shall constitute one and the same instrument.

10.6Expenses. Except as otherwise provided below or elsewhere herein, each Party hereto will pay all costs and expenses incident to its negotiation and preparation of this

Agreement and to its performance and compliance with all agreements and conditions contained herein on its part to be performed or complied with, including the fees, expenses and disbursements of its counsel and accountants. Notwithstanding the foregoing, all fees related to filings pursuant to the HSR Act and any other Antitrust Laws shall be the sole responsibility and liability of Buyer.

10.7Headings; Interpretation. The article and section headings contained in this Agreement are inserted for convenience only and shall not affect in any way the meaning or interpretation of this Agreement. Each reference in this Agreement to an Article, Section, Schedule or Exhibit, unless otherwise indicated, shall mean an Article or a Section of this Agreement or a Schedule or Exhibit attached to this Agreement, respectively. References herein to “days”, unless otherwise indicated, are to consecutive calendar days. All Parties have participated substantially in the negotiation and drafting of this Agreement and agree that no ambiguity herein should be construed against the draftsman. For the purposes of determining whether any amount of local currency exceeds or is less than any U.S. Dollar amount referred to in this Agreement, the exchange rate prevailing on the relevant date (or, if the relevant date is not a Business Day, on the immediately preceding Business Day) as published by the New York Times shall be used. References to a “corporation” or “company” shall be construed so as to include any corporation, company or other body corporate, wherever and however incorporated or established.

10.8Bulk Sales Laws. Buyer and the Seller each hereby waive compliance by the Seller with the provisions of the “bulk sales,” “bulk transfer” or similar laws of any state or province.

10.9Governing Law. This Agreement shall be governed by, and construed in accordance with, the law of the State of Illinois applicable to contracts to be carried out wholly within such State.

10.10Submission to Jurisdiction. Each of the Parties hereto irrevocably submits to the exclusive jurisdiction of (a) the circuit courts located in Cook County, Illinois, and (b) the United States District Court for the Northern District of Illinois for the purposes of any suit, action or other proceeding arising out of this Agreement or any transaction contemplated hereby. Each of the Parties agrees to commence any action, suit or proceeding relating hereto in the United States District Court for the Northern District of Illinois, or if such suit, action or other proceeding may not be brought in such court for jurisdictional reasons, in the state courts located in Cook County, Illinois. Each of the Parties further agrees that service of any process, summons, notice or document by U.S. registered mail to such Party’s respective address set forth above shall be effective service of process for any action, suit or proceeding in Illinois with respect to any matters to which it has submitted to jurisdiction in this Section 10.10. Each of the Parties irrevocably and unconditionally waives any objection to the laying of venue of any action, suit or proceeding arising out of this Agreement or the transactions contemplated hereby in (i) the state courts located in Cook County, Illinois, or (ii) the United States District Court for the Northern District of Illinois, and hereby further irrevocably and unconditionally agrees not to plead or claim in any such court that any such action, suit or proceeding brought in any such court has been brought in an inconvenient forum or to raise any similar defense or objection.

10.11Disclosure Generally. ESCO shall use its reasonable efforts to specifically identify and list on each Disclosure Schedule that information which is relevant to such Disclosure Schedule. Any disclosure with respect to a Section, Schedule, or Disclosure Schedules shall be deemed to be disclosed for other Sections, Schedules and Disclosure Schedules to the extent such disclosure sets forth facts in sufficient detail so that the relevance of such disclosure to such other Sections, Schedules and Disclosure Schedules would be reasonably apparent to a reader of such disclosure. Except as expressly set forth to the contrary herein, by listing matters on the Disclosure Schedules, ESCO or any of its Affiliates shall not be deemed to have established any materiality standard, admitted any Liability, or concluded that any one or more of such matters are material, or expanded in any way the scope or effect of the representations and warranties of ESCO contained in this Agreement.

10.12No Waiver. No disclosure of information made in this Agreement or required to be made pursuant to this Agreement shall be deemed to constitute a waiver of the Attorney-Client privilege or work-product doctrine, or to the extent such disclosure could be so construed, the Parties shall enter into a mutually acceptable agreement to protect such disclosure.

10.13No Third Party Beneficiaries or Other Rights. Except as set forth in Section 9.6, nothing herein shall grant to or create in any Person not a party hereto, or any such Person’s Affiliates, employees, or any other third party, any right to any benefits hereunder, and no such party shall be entitled to sue either Party to this Agreement with respect thereto. The representations and warranties contained in this Agreement are made for purposes of this Agreement only and shall not be construed to confer any additional rights on the Parties under applicable state or federal or foreign securities laws.

10.14Amendment and Waiver. Any provision of this Agreement may be amended or waived only if such amendment or waiver is in writing and signed, in the case of an amendment, by ESCO and Buyer, or in the case of a waiver, by the party against whom the waiver is to be effective. No failure or delay by any party in exercising any right, power or privilege hereunder shall operate as a waiver thereof.

11.1Dispute Resolution. Subject to the provisions of Section 11.5, any dispute arising out of or relating to this Agreement, including, but not limited to, claims for indemnification pursuant to ARTICLE IX other than under Section 2.5 shall be resolved in accordance with the procedures specified in this ARTICLE XI which shall be the sole and exclusive procedures for the resolution of any such disputes. Notwithstanding the foregoing, any dispute regarding the Closing Adjustment shall be resolved in accordance with Section 2.5.

11.2Negotiation Between Executives.

(a) The Parties shall attempt in good faith to resolve any dispute arising out of or relating to this Agreement promptly by negotiation between the appointed representative of the Seller and executives of Buyer who, if possible, are at a higher level of management than the persons with direct responsibility for administration of this Agreement. Any party may give the

other party written notice of any dispute not resolved in the normal course of business. Within 15 days after delivery of the notice, the receiving party shall submit to the other a written response. The notice and response shall include (i) a statement of each party’s position, and (ii) the name and title of the executive who will act as such party’s representative. Within 30 days after delivery of the disputing party’s notice, the representatives of ESCO and the Buyer shall meet at a mutually acceptable time and place, and thereafter as often as they reasonably deem necessary to attempt to resolve the dispute. All reasonable requests for information made by one party to the other will be honored. All negotiations pursuant to this clause are confidential and shall be treated as compromise and settlement negotiations for purposes of the Federal Rules of Evidence and State Rules of Evidence.

(b) If the matter has not been resolved by these persons within 60 days of the disputing party’s notice, or if the parties fail to meet within 30 days, either party may initiate mediation as provided hereinafter.

(c) All negotiations pursuant to this clause are confidential and shall be treated as compromise and settlement negotiations for purposes of the Federal Rules of Evidence and State Rules of Evidence.

11.3Mediation. If the dispute has not been resolved by negotiation as provided herein, the parties shall endeavor to settle the dispute by mediation under the then current Center for Public Resources (“CPR”) Model procedure for Mediation of Business Disputes. The neutral third party will be selected from the CPR Panels of Neutrals, with the assistance of CPR, unless the parties agree otherwise.

11.4Litigation. If the dispute has not been resolved by the procedures provided for in Section 11.2 and Section 11.3 within 90 days of the initiation of such procedures, either party may initiate litigation upon 30 days written notice to the other Party;provided,however, that if one Party has requested the other to participate in such procedures and the other Party has failed to participate, the requesting party may provide written notice of its intent to initiate litigation prior to the expiration of such 90-day period.

11.5Exclusive Procedure. The procedures specified in this ARTICLE XI shall be the sole and exclusive procedures for the resolution of disputes between the parties arising out of or relating to this Agreement;provided,however, that any Party may, without prejudice to the above procedures, seek preliminary injunction if in its sole judgment such action is necessary to avoid irreparable damage or to preserve the status quo. Despite such action the Parties will continue to participate in good faith in the procedures specified in this ARTICLE XI.

11.6Tolling Statute of Limitations. All applicable statutes of limitation and defenses based upon the passage of time shall be tolled while the procedures specified in Section 11.2 are pending. The parties will take such action, if any, required to effectuate such tolling.

11.7Performance to Continue. Each party is required to continue to perform its obligations under this Agreement pending final resolution of any dispute arising out of or relating to this Agreement.
