1.2 Purchase Price. The total purchase price for the Stock shall be $17,216,044 [based on the most recent available month-end balance sheet less $1,750,000] (the “Purchase Price”), which may be increased or decreased post-Closing by the Purchase Price Adjustment, if any.

ARTICLE II

OTHER AGREEMENTS

2.1 Conduct of the Business Until Closing. Except as provided in Sections 2.3 and 2.4 below, from and after the date of this Agreement and until the Closing Date, Sellers will cause the Subsidiaries to conduct the Business in accordance with the following provisions:

2.1.1 Carry on in Regular Course. The Subsidiaries shall carry on the Business in the regular course and in substantially the same manner as heretofore carried on without implementing any unusual methods of purchase, sale, management, accounting or operations that vary in a material manner from the methods used in 2002 and preserve its material properties, business and relationships with its employees, suppliers and customers. The Sellers or Subsidiaries shall use commercially reasonable efforts to promptly advise Purchaser in writing if the Subsidiaries suffer a Material Adverse Effect in any of their financial condition, business or affairs.

2.1.2 Indebtedness. The Subsidiaries shall not (a) create, incur or assume any material Indebtedness for borrowed money without the prior written consent of Purchaser; (b) mortgage, pledge or otherwise materially encumber any of its properties or assets; and (c) create or assume any other material Indebtedness, except accounts payable incurred in the ordinary course of business.

2.1.3 Issuance and Redemption of Stock. The Subsidiaries shall not issue any shares of stock of any class or grant any warrants, options or rights to subscribe for any share of stock of any class of securities convertible into or exchangeable for, or which otherwise confer on the holder any right to acquire, any shares of stock of any class.

2.1.4 Employment Terms; Compensation. Except in the ordinary course of business or as disclosed in the Disclosure Schedule, the Subsidiaries shall not: (i) enter into any new employment contract or extend or modify the terms of any existing employment contract or other arrangement, or grant any increases in the rate of pay of any of its employees; (ii) amend any existing employee benefit plan or institute any new employee benefit plan or grant any increases in employee fringe benefits, without the prior written consent of Purchaser; or (iii) make any loans to any employee or other person.

2.1.7 No Commitments. No Subsidiary may enter into any agreements or commitments obligating it to any of the foregoing prohibited actions.

2.1.8 Compliance With Law. The Subsidiaries will comply, in all material respects, with all applicable Legal Requirements and Orders.

2.2 Acquisition Review. Purchaser and its authorized agents, officers and representatives shall have reasonable access to the properties, books, records, contracts, information and documents of the Subsidiaries to conduct such examinations and investigations of the Subsidiaries as it reasonably deems necessary (the “Acquisition Review”). Inspection by Purchaser shall not relieve the Sellers of their obligations under this Agreement or constitute a waiver by Purchaser of any of the representations and warranties under Article III. The Subsidiaries shall cooperate in all reasonable respects with the Acquisition Review, including providing Purchaser with such operating data and other information with respect to the assets and the Business as Purchaser shall from time to time reasonably request; provided that Seller shall not have any obligation to disclose customer names, pricing information, cost information, or similar proprietary competitive information at any time prior to Closing. Purchaser shall conduct the Acquisition Review with a minimum of disruption to the Business, and shall direct and coordinate all of its requests through Xxxx Xxxxxx. Purchaser may, at its sole cost and expense, engage an environmental engineering firm to perform environmental site assessments, accompanied by a designated representative of the Seller, which do not contain invasive testing or sampling, to investigate compliance with Environmental Laws (“Phase I Sampling”). The Subsidiaries shall be responsible for correction of matters disclosed in the Phase I Sampling and neither Seller nor Seller Guarantor shall have any liability in connection with such matters. Purchaser acknowledges and agrees that pre-Closing invasive testing or sampling (“Phase II Sampling”) will not be permitted without the prior written consent of Sellers. Sellers shall have the right to determine in its sole discretion whether to allow Purchaser to proceed with Phase II Sampling and to approve the scope of such Phase II Sampling. If such Phase II Sampling is permitted by Sellers, the scope and conditions of such sampling shall be set forth in writing by the Purchaser for the Sellers’ review and approval. The Purchaser and its agents shall strictly abide by the conditions and limitations set forth in the written instructions approved by Sellers (unless the Agreement is terminated by Purchaser in accordance with Section 8.1.2). Purchaser shall, if requested by Sellers, provide copies of all reports, including Phase I and Phase II Sampling reports, to Sellers. If Phase II Sampling is undertaken but the Contemplated Transactions are not consummated, Purchaser will restore all property of the Subsidiaries to its condition prior to the Phase II Sampling and will indemnify and hold Sellers and the Subsidiaries harmless from and against any damages caused by the Phase II Sampling.

2.4 Employment Agreements. On or before Closing, Purchaser shall offer employment agreements to Xxx Xxxxxx, Xxx Xxxxx, Xxxxx Xxxxx and Xxxx Xxxxxxxxx in substantially the form attached hereto as Exhibit 3 and otherwise upon terms and conditions satisfactory to Purchaser (the “Employment Agreements”).

2.5 Preparation of Consolidated Balance Sheet. In order to determine the Consolidated Net Worth, Purchaser shall cause to be prepared and delivered to the Sellers within 60 days after Closing the Consolidated Balance Sheet. The parties shall cooperate in every reasonable way in the preparation of the Consolidated Balance Sheet, and each of them shall have the right to review all pertinent working papers. The Sellers shall notify Purchaser within 30 days after the receipt of a copy of the Consolidated Balance Sheet if they consider it to be erroneous in any respect (the “Dispute Notice”). If the parties are unable, within 30 days after the date on which such Dispute Notice was given, to resolve the matter by agreement, then for a period of 30 days thereafter either the Sellers or Purchaser shall have the right to demand that the disputed items be determined by binding arbitration by written notice to the other (the “Demand”). If the parties cannot mutually agree on a method of binding arbitration within 15 days after the Demand, then the parties shall mutually select a firm of independent certified public accountants (the “Arbitrator”), whose good faith final determination of the disputed items shall be binding and conclusive on the parties, their successors and assigns. The Arbitrator shall provide to each Purchaser and the Sellers a copy of its preliminary report of finding within 45 days after selection, and each of the parties shall have 30 days after receipt of the draft to comment thereon. The Arbitrator shall make its final determination regarding any disputed items within 110 days after the selection. If Purchaser and the Sellers cannot agree on the selection of the Arbitrator within 10 days after the request of either, or if the Arbitrator fails to make its report as required herein, then any judge of a court of competent jurisdiction shall, at the request of either, appoint the Arbitrator. If neither of the Sellers deliver a Dispute Notice within the appropriate time period then the Consolidated Balance Sheet as submitted by Purchaser shall be final and conclusive and binding upon all parties for all purposes. The reasonable fees and expenses of the Arbitrator in making such review shall be paid one-half by Purchaser and one-half by the Sellers.

2.6 Cooperation. Purchaser and the Sellers shall cooperate in all respects in connection with the giving of any notices to any third party (including any Governmental Body) or securing the Consent of any third party required in connection with the transactions contemplated by this Agreement (“Third Party Consents”), if any.

2.7 Confidentiality and Public Statements. The terms and conditions of this Agreement shall remain confidential, and all general notices, releases, statements and communications to employees, suppliers, distributors and customers of the Subsidiaries or Purchaser and to the general public and the press relating to the transactions covered by this Agreement shall be made only at such times and in such manner as may be mutually agreed upon by Purchaser and Sellers. Any and all information, disclosures, knowledge or facts regarding the Sellers and the Subsidiaries, its business and its operation and properties, derived from or resulting from the Purchaser’s Acquisition Review or otherwise obtained by the Purchaser pursuant to or in

connection with this Agreement shall be confidential and shall not be divulged, disclosed or communicated to any other person, firm, corporation or entity, except as required by law and except to the officers, directors, employees, agents, attorneys, financial advisors and accountants of Purchaser, its lenders and other potential financing sources for the purpose only of evaluating, financing and consummating the Contemplated Transactions, who shall be bound by the confidentiality restrictions, and the Purchaser shall be responsible for any breach of confidentiality by any such person or representative. Notwithstanding the foregoing, the following information shall not be confidential: (a) information that is known to the receiving party prior to disclosure by the disclosing party; (b) information that is, at the time of disclosure by the disclosing party or at any time thereafter becomes, public through no fault of the receiving party; (c) information that is received by the receiving party from a third party under no obligation or confidence, express or implied, to the disclosing party; or (d) information that is required to be disclosed by operation of law. If this Agreement terminates before Closing, the Purchaser shall return promptly any information obtained regarding the Sellers, the Subsidiaries, its business and its operations and properties and the Purchaser shall instruct its representatives also to return any such information regarding the Sellers, the Subsidiaries, its business and its operations and properties. In addition, the Purchaser’s confidentiality obligations outlined hereunder shall survive termination of this Agreement.

2.8 Prohibited Competition. Each of the Sellers and the Seller Guarantor agrees, in consideration of the Purchase Price for the Stock to be paid by Purchaser hereunder, that it will not without the prior written consent of the Purchaser take any of the following actions:

2.8.1 For a period of five years from the Closing Date, directly or indirectly engage in the Business in North America;

2.8.2 For a period of five years from the Closing Date, either individually or on behalf of or through any third party, compete with the Subsidiaries in the Business; or

2.8.3 For a period of three years from the Closing Date, knowingly solicit, entice or persuade any employee of the Subsidiaries to leave the services of the Subsidiaries for any reason.

Sellers and Seller Guarantor acknowledge that, in the event of a breach or threatened breach of any of the terms of this section, Purchaser and/or the Subsidiaries will suffer irreparable injury for which there is no adequate remedy at law. Purchaser and the Subsidiaries shall have the right to seek a remedy at law as well as, or in lieu of, equitable relief in the event of any such breach.

2.9 Taxes for Periods Prior to Closing.

2.9.1 Federal Income Tax and Returns for Periods Through Closing Date. Seller Guarantor shall include the income of the Subsidiaries on its consolidated federal

income Tax Returns for all periods through the end of the Closing Date and pay any federal income Taxes attributable to such income. For United States federal income Tax purposes, the income of the Subsidiaries shall be apportioned to the period up to and including the Closing Date and the period after the Closing Date by closing the books of the Subsidiaries as of the end of the Closing Date. Purchaser or Purchaser Guarantor shall cause Subsidiaries to furnish information to Seller Guarantor and Sellers as reasonably requested by Seller Guarantor to allow Seller Guarantor to satisfy its obligations under this section in accordance with past custom and practice.

2.9.2 Tax Indemnification. Seller Guarantor shall indemnify Purchaser and Subsidiaries and hold them harmless from and against all Taxes of Subsidiaries and Taxes of other members of the Seller Guarantor Affiliated Group that are imposed on Subsidiaries by statute or contract for all Taxable periods: (i) ending on or before the Closing Date; and (ii) the portion through the end of the Closing Date for any taxable period that includes (but does not end on) the Closing Date (a “Straddle Period”); provided, however, that Seller Guarantor shall be liable only to the extent that such Taxes are in excess of the amount, if any, reserved for such Taxes (excluding any reserve for deferred Taxes established to reflect timing differences between Tax and book income) on the face of the Consolidated Balance Sheet and used to determine the Purchase Price Adjustment.

2.9.3 Straddle Period. In the case of any Straddle Period: (i) the amount of real property, personal property and other ad valorem Taxes which relate to the portion of such Straddle Period through the end of the Closing Date shall be deemed to be the amount of such Tax for the entire Straddle Period multiplied by a fraction, the numerator of which is the number of calendar days in the Straddle Period ending on the Closing Date and the denominator of which is the total number of calendar days in such Straddle Period; and (ii) the amount of all other Taxes for the portion of the Straddle Period through the end of the Closing Date shall be determined based on an interim closing of the books as of the close of business on the Closing Date.

2.9.4 Responsibility for Filing Tax Returns. Purchaser shall prepare or cause to be prepared and file or cause to be filed all Tax Returns for Subsidiaries for Tax periods ending on or before the Closing Date that are required to be filed after the Closing Date (other than the Seller Guarantor’s consolidated federal income Tax Returns described in Section 2.9.1 herein and any other state, local, or foreign Tax Returns with respect to which any Subsidiary is included as a member of a consolidated, combined, or unitary group of Seller Guarantor or any Seller, which Tax Returns shall be prepared and filed by Seller Guarantor or Sellers) and shall prepare or cause to be prepared and file or cause to be filed all Tax Returns for Subsidiaries relating to any Straddle Period. Purchaser shall permit Seller

Guarantor to review and comment on each such Tax Return prior to filing and shall make such revisions to such Tax Returns requested by Seller Guarantor that Purchaser in good faith determines are appropriate.

2.9.5 Tax Sharing Agreements. Any tax sharing agreement between Seller Guarantor and any of the Subsidiaries or Sellers and any of the Subsidiaries shall be terminated as of the Closing Date and shall have no further effect for any taxable year (whether the current year, a future year, or past year).

2.9.6 Indemnification for Post-Closing Transactions. Purchaser, Purchaser Guarantor, Seller Guarantor and Sellers agree to report all transactions not in the ordinary course of business occurring on the Closing Date after Purchaser’s purchase of Subsidiaries’ stock on Purchaser Guarantor’s federal income Tax Return to the extent permitted by Treasury Regulations § 1.1502-76(b)(1)(ii)(B). Purchaser and Purchaser Guarantor, jointly and severally, agree to indemnify Seller Guarantor and Sellers for any additional Tax owed by Seller Guarantor or Sellers resulting from any transaction engaged in by Subsidiaries not in the ordinary course of business occurring on the Closing Date after Purchaser’s purchase of the Stock.

2.9.7 Certain Taxes and Fees. All transfer, documentary, sales, use, stamp, registration and other such Taxes, and all conveyance fees, recording charges, and other fees and charges (including any penalties and interest) incurred in connection with the consummation of the transactions contemplated hereby shall be borne by Purchaser.

Purchaser, Purchaser Guarantor, Seller Guarantor, Sellers and Subsidiaries shall cooperate fully, as and to the extent reasonably requested by the other party, in connection with the filing of Tax Returns pursuant to this Section 2.9 and any audit, litigation or other proceeding with respect to Taxes. Such cooperation shall include the retention and (upon the other Party’s request) the provision of records and information which are reasonably relevant to any such audit, litigation or other proceeding and making employees available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder. Purchaser, Seller Guarantor, Sellers and Subsidiaries agree (i) to retain all books and records with respect to Tax matters pertinent to Subsidiaries relating to any taxable period beginning before the Closing Date until the expiration of the relevant statute of limitations (including any extensions thereof) of the respective taxable periods, and to abide by all record retention agreements entered with any taxing authority, and (ii) to give the other party reasonable written notice prior to transferring, destroying or discarding any such books and records and, if the other party so

requests, Purchaser, Seller, Seller Guarantor or Subsidiaries, as the case may be, shall allow the other party to take possession of such books and records.

2.10 Certain Notices to Sellers. Prior to Closing, Purchaser or Purchaser Guarantor agrees to give Sellers notice of any breach of a representation and warranty by Sellers of which it has Knowledge prior to Closing, and Purchaser, Purchaser Guarantor, and Subsidiaries agree to give Sellers notice of any claims made after Closing by Purchaser, Purchaser Guarantor, or any Subsidiary with respect to the insurance policies listed in Section 3.19 of the Disclosure Schedule. Failure to give any such notice shall not be deemed to amend the Disclosure Schedule or Article VII or to prevent or cure any breach of a representation or warranty.

2.11 Defined Benefit Plan Benefits.

2.11.1 The Seller Guarantor shall cause to be amended, effective on the Closing Date, its defined benefit pension plan as defined in Section 3(35) of ERISA, and known as the Ampco-Pittsburgh Corporation Retirement Plan (the “Seller Pension Plan”) to provide for the transfer of assets and liabilities with respect to (i) those employees of the Business who participate in the Seller Pension Plan on the Closing Date and who are employees of the Business on the Closing Date and (ii) those deferred vested and retired former Participants in the Seller Pension Plan who were employed at locations comprising the Business (collectively, the “Transferred Participants”) in their accrued benefit as of the Closing Date. Effective upon the Closing Date, the Purchaser shall assume the liabilities and obligations for funding, payment and administration of accrued benefits of all Transferred Participants under the Seller Pension Plan as of the Closing Date. The Purchaser shall have established as of the Closing Date, or shall establish as soon as practicable after the Closing Date, a tax-qualified defined benefit pension plan or plans which shall discharge the pension obligations of the Purchaser set forth in this Section with regard to the accrued benefits of Transferred Participants (“Purchaser Pension Plan”). As soon as practicable after the Closing Date, the Seller Guarantor shall cause a transfer of the pension liabilities and obligations being assumed by Purchaser and of the assets, as calculated below, from the Seller Pension Plan to Purchaser Pension Plan and Seller Guarantor shall cause to be provided to the fiduciaries and administrators of the Purchaser Pension Plan such records regarding the Transferred Participants as are necessary for the proper administration of the Purchaser Pension Plan.

2.11.2 The assets to be transferred from the Seller Pension Plan to the Purchaser Pension Plan shall be an amount equal to the projected benefit obligations of the Seller Pension Plan with respect to the Transferred Participants as of the Closing Date as determined using the actuarial and financial assumptions applied to the Seller Pension Plan as an ongoing plan as of December 31, 2002 for purposes of preparation of the financial reporting and disclosure of Seller Guarantor, with

adjustments, if any, described below. Seller Guarantor’s actuary shall calculate the amount of assets to be transferred (the “Transfer Amount”) by applying the assumptions, methods and methodologies used, as of December 31, 2002, in the preparation of financial statements of Seller Guarantor. Notwithstanding any provision herein to the contrary, the transfer amount shall not be less than the amount required by Sections 414(1) and 401(a)(12) of the IRC. The Transfer Amount determined by the Seller’s actuary shall be adjusted for investment earnings at the actual rate of return of the EB Temporary Investment Fund (the “Earnings”) for the period between the Closing Date and the actual dates of transfer (see below) and reduced by the amount of any benefit payments to Transferred Participants and a proportional share of investment and administrative expenses incurred by or on behalf of Seller Pension Plan relative to asset values for such period. The amount of assets caused to be transferred pursuant to this Section 2.11 shall be calculated by Seller Guarantor’s actuary and reported to Purchaser in reasonable detail within 60 days after the Closing Date (“Plan Calculations”). Purchaser shall have the right to review all pertinent working papers. The Purchaser shall notify the Seller Guarantor within 60 days after receipt of the Plan Calculations if it considers them to be erroneous in any respect, and thereafter the matter shall be resolved in the same manner as disputes with respect to the Consolidated Balance Sheet are resolved in accordance with Section 2.4, with such notice from Purchaser being treated as a “Dispute Notice.” The transfer of assets from Seller Pension Plan to Purchaser Pension Plan shall be made in cash. The Seller Guarantor and the Purchaser shall each file on a timely basis any IRS Forms 5310-A required with respect to such transfer.

2.11.3 All transfers from the Seller Pension Plan to the Purchaser Pension Plan shall be made in accordance with the provisions of this Section 2.11. As soon as is administratively practical, but in no event later than 30 days after Purchaser provides Seller Guarantor with evidence reasonably satisfactory to it that Purchaser has established a qualified trust (or trusts) under Section 501(a) of the IRC to hold the assets of the Purchaser Pension Plan and that Purchaser Pension Plan is qualified under Section 401(a) of the IRC (“Initial Transfer Date”), Seller Guarantor shall cause its trusts under the Seller Pension Plan to make an initial transfer of assets in cash equal to 85% of the amount reasonably estimated by Seller Guarantor’s Actuary in good faith to be equal to the Transfer Amount (the “Initial Transfer Amount”). In addition, prior to the Initial Transfer Date, Seller Guarantor shall provide Purchaser with evidence reasonably satisfactory to Purchaser that the Seller Pension Plan remains qualified under Section 401(a) of the IRC. As soon as practicable, and in any event within 30 days, after the final determination of the amounts to be transferred (“True-Up-Date”), Seller Guarantor shall cause a second transfer to be made in cash of the “True-Up Amount.” The True-Up Amount shall be equal to the following amount:

(Transfer Amount minus Initial Transfer Amount), minus the sum of (i) benefit payments made to Transferred Participants since the Closing Date from the Seller Pension Plan and (ii) the appropriate share of expenses of Seller Pension Plan and plus Earnings on the excess of the Transfer Amount over the Initial Transfer Amount from the Initial Transfer Date to the True-Up Date.

If the Initial Transfer Amount exceeds the Transfer Amount, as soon as practicable following such determination, Purchaser shall cause a transfer to be made to the respective Pension Plan equal to the excess of the Initial Transfer Amount over the Transfer Amount, adjusted to reflect earnings at the short term investment fund rate available to the Purchaser Pension Plan from the Initial Transfer Date until the date of transfer.

2.12 Defined Contribution Plan Benefits.

2.12.1 Plans Sponsored by Atlantic Grinding and F. R. Gross. Atlantic Grinding sponsors the Atlantic Grinding & Welding Savings & Retirement Plan and F. R. Gross sponsors the F. R. Gross Company Savings and Retirement Plan (the “Sponsored Plans”). The Sponsored Plans shall, by operation of law, be and remain the plans of and responsibility of Atlantic Grinding and F. R. Gross on and after the Closing Date. Seller Guarantor shall cause to be delivered as soon as reasonably practical after the Closing Date such records as are not in the possession of Atlantic Grinding and/or F. R. Gross on the Closing Date as are necessary to the proper administration of the Sponsored Plans.

2.12.2 Ampco-Pittsburgh Corporation Retirement Savings Plan (“Seller’s Defined Contribution Plan”). As of the Closing Date, Seller Guarantor shall cause to be amended Seller’s Defined Contribution Plan to (i) cease contributions to such plan with respect to Transferred Participants and (ii) to transfer to a qualified defined contribution plan established by Purchaser the liability to pay and administer the accrued benefits of all Transferred Participants together with an amount of cash equal to such accrued benefits. The transfer of accrued benefits shall be made as soon as administratively practical, but in no event later than 30 days following the delivery by the Purchaser of evidence reasonably satisfactory to Seller that Purchaser has established a trust or trusts qualified under Section 501(a) of the IRC to hold the accrued benefits.

2.13 Lease Guarantee. New Castle Industries, Inc. has entered into a Guaranty of Lease dated December 3, 2002, for the benefit of the Xxxxxxx X. Xxxxxxx Trust with respect to a lease of South Carolina real estate. Sellers and Seller Guarantor shall indemnify Purchaser and Subsidiaries and hold them harmless from and against any liability, cost and expense arising out of or in connection with the Guaranty of Lease.

2.14 Title Insurance. Prior to Closing, Purchaser, at its sole cost and expense, will cause current title insurance commitments to be issued by a reputable and financially responsible title insurance company to be selected by Purchaser (collectively, the “Title Commitments”), showing marketable title to be vested in a Subsidiary of each parcel of real estate listed in Section 3.11 of the Disclosure Schedule and committing to insure such title by the issuance of a 1992 ALTA form of extended coverage policies of owner’s title insurance, as the case may be (the “Title Policies”), in such amounts that the Purchaser reasonably determines to approximate the value of such parcels of real estate.

2.15 Environmental Remediation. If Phase II Sampling is undertaken in accordance with Section 5.3, unless this Agreement is terminated in accordance with Section 8.1, upon completion of the Phase II Sampling, Sellers agree to pay for (subject to reimbursement as set forth below), perform and control Cleanup of any Environmental Condition revealed by the Phase II Sampling (“Remediation”); provided in no event shall the Sellers be responsible for any Remediation after Sellers’ costs and/or expenses exceed (excluding Environmental Reimbursements made by Purchaser) the Indemnification Cap. In the event the projected Cleanup cost is less than $250,000.00, the Purchaser shall have the right at its option, but not the obligation, to control the Remediation, and if Purchaser so elects to control the Remediation, the Sellers will have no further obligation with respect to the Remediation. The Remediation shall not be required to exceed the least stringent standards required by applicable Governmental Body(ies) and to comply with applicable Environmental Laws for the current use of the affected land. Purchaser agrees to reimburse Sellers’ out-of-pocket costs and expenses reasonably incurred in performing the Remediation up to an aggregate amount of $250,000.00 (“Environmental Reimbursements”). The Purchaser may attend and participate in any meeting the Sellers may have with any Governmental Body regarding any such Cleanup. The Remediation and the performance thereof shall not, without Purchaser’s prior written consent, (i) unreasonably interfere with the operation of the Business, or (ii) impose any material additional cost or expense upon any of the Subsidiaries in the operation of the Business after Closing. Sellers will use all commercially reasonable efforts to perform and expeditiously complete the Remediation, and Purchaser shall cooperate with Sellers in every reasonable way in the performance of the Remediation. Sellers and Purchaser acknowledge that (i) the Remediation may require land use and/or deed restrictions and other similar limitations that do not unreasonably interfere with future use of the land consistent with its current use in the Business, (ii) the Remediation may require additional investigations and analyses after Closing before a comprehensive remediation plan can be developed, and (iii) the Remediation itself may require further testing and monitoring after Closing that might clarify and/or disclose pre-Closing Environmental Conditions requiring additional Cleanup for which Sellers will be responsible (subject to the provisions of this Section 2.15). The Remediation shall be sufficient to receive sign-off and closure from the appropriate Governmental Body(ies).

All of the representations and warranties contained in Articles III and IV above shall survive the Closing for a period of two (2) years thereafter, except with respect to claims made prior thereto which shall be continuing, and except (i) the representations and warranties set forth in Sections 3.1, 3.3 and 3.5 shall survive

indefinitely, (ii) the representations and warranties set forth in Sections 3.14 and 3.21 shall survive the Closing for a period of four (4) years, and (iii) the representations and warranties in Sections 3.9 and 3.18 shall survive the Closing until the applicable statutes of limitations with respect to the liabilities in question expire (after giving effect to any extensions or waivers thereof), plus 60 days. Any claim for indemnification based upon a breach of representation and warranty shall be made prior to the expiration of the applicable survival period for such representation and warranty.

7.2 Indemnification by the Sellers and Seller Guarantor.

7.2.1 If the Purchaser gives written notice of a claim for indemnification against any of the Sellers or Seller Guarantor in accordance with Section 7.5 below and there is an applicable survival period for the claim pursuant to Section 7.1 above and the notice is given within that time period, then, subject to the terms hereof, the Sellers and Seller Guarantor, jointly and severally, agree to indemnify and to hold Purchaser and the Subsidiaries harmless from and against, and agree to defend promptly Purchaser and the Subsidiaries from, and reimburse Purchaser and the Subsidiaries for, any and all losses, damages, costs, expenses, liabilities, obligations and claims of any kind, including without limitation reasonable attorneys’ fees and other legal costs and expenses, but such payments shall not include punitive or consequential damages unless such damages arise from third-party claims (collectively, “Losses”) that Purchaser and the Subsidiaries suffer or incur or become subject to with respect to or arising out of (i) any breach, inaccuracy or failure of any covenant, representation or warranty made by the Sellers in this Agreement, (ii) the matter set forth in item 2 of Section 3.9 and the matters set forth on Section 3.20 of the Disclosure Schedule and/or (iii) enforcement of this Agreement.

7.2.2 Notwithstanding the foregoing and subject to the provisions of Section 7.2.3 below, Purchaser and, following the Closing, the Subsidiaries shall not be entitled to any recovery for Losses suffered as a result of a breach of any representation and warranty of Sellers unless and until the aggregate amount of all Losses suffered by Purchaser and the Subsidiaries exceeds a cumulative aggregate deductible of (i) $250,000.00 less (ii) if any, Environmental Reimbursements paid to Sellers pursuant to Section 2.15 (the “Indemnification Basket”), and then only for the amount by which Losses exceed the Indemnification Basket, and the cumulative aggregate liability for all such Losses shall not exceed twenty-five percent (25%) of the Purchase Price (the “Indemnification Cap”). Furthermore, in the event Purchaser had Knowledge of a breach of a representation or warranty made in Article III of this Agreement and failed to notify Sellers prior to Closing, then to the extent Sellers and Seller Guarantor were prejudiced by such failure to notify, Purchaser and Purchaser Guarantor shall not be entitled to indemnification of Losses arising out of such breach.

7.2.3 For those Losses suffered due to Environmental Liabilities arising out of any breach of a representation or warranty in Section 3.21 discovered post-Closing (other than those Environmental Liabilities discovered in connection with the Remediation and those discovered by a Governmental Body directed inspection), Purchaser shall be responsible for the first $100,000.00 of Environmental Liabilities or Cleanup cost over and above and in addition to the Indemnification Basket. Purchaser acknowledges that Purchaser shall bear the burden to prove that such Losses arise out of Environmental Liabilities existing prior to Closing.

7.2.4 Notwithstanding anything above to the contrary, it is expressly understood that the obligations of Sellers to pay costs and expenses to perform and complete the Remediation shall not exceed, in the aggregate, the Indemnification Cap.

7.3 Indemnification by the Purchaser and Purchaser Guarantor.

7.3.1 Breach. If the Sellers give written notice of a claim for indemnification against the Purchaser or Purchaser Guarantor in accordance with Section 7.5 below and there is an applicable survival period for the claim pursuant to Section 7.1 above and the notice is given within that time period, then subject to the terms hereof, the Purchaser and Purchaser Guarantor, jointly and severally, agree to indemnify and to hold the Sellers harmless from and against, and agree to defend promptly the Sellers from and reimburse the Sellers for, any and all Losses that the Sellers may at any time suffer or incur, with respect to or arising out of any breach or inaccuracy of any of the representations, warranties and covenants made by Purchaser in or pursuant to this Agreement.

7.3.2 Indemnification for Insurance.

(a) Purchaser and Purchaser Guarantor agree that, with respect to Losses suffered by Purchaser, Purchaser Guarantor, or Subsidiaries after Closing that are subject to indemnification under this Article VII and are covered by any insurance applicable to the Subsidiaries and which was in effect prior to Closing, any retrospective or retroactive premium adjustments, self-insured retentions, deductibles and/or any other self insurance costs, including service or other charges associated with the foregoing, paid by the Sellers or Seller Guarantor to the extent arising from a claim made by Purchaser Guarantor, Purchaser, or Subsidiaries after Closing (“Insurance Losses”) shall be subject to and covered by the Indemnification Basket and the Indemnification Cap and any payment by the Sellers or Seller Guarantor in respect of such Insurance Losses shall apply to the Indemnification Cap discussed above in Section 7.2.2.

(b) If,

(i) the aggregate amount of the Sellers’ indemnification exceeds the Indemnification Cap (including the Sellers’ Insurance Losses just discussed) or

(ii) the Purchaser, Purchaser Guarantor, or Subsidiaries suffer any Losses that are not subject to indemnification under this Article VII but are covered by insurance in place prior to Closing and collection on such insurance will cause Insurance Losses to Sellers or Seller Guarantor

then, Subsidiaries, Purchaser and Purchaser Guarantor, jointly and severally, agree to pay each of the Sellers and the Seller Guarantor any Insurance Losses the Sellers or Seller Guarantor may suffer, prior to the claim for any Losses being paid by the insurer.

(c) Sellers and Seller Guarantor shall be responsible for liabilities arising from the issues disclosed in item 2 of Section 3.9 and all of Section 3.20 of the Disclosure Schedule (including, without limitation, workers compensation claims incurred, but not reported, prior to Closing) and agrees to indemnify Purchaser, Purchaser Guarantor and, after Closing, the Subsidiaries from Losses arising out of such liabilities; provided, however, the Purchaser, Purchaser Guarantor, and Subsidiaries agree that any workers’ compensation claims arising from re-injuries post Closing shall be covered by Purchaser, Purchaser Guarantor, or Subsidiaries.

7.4 Matters Involving Third Parties.

7.4.1 If any third party shall notify any party (the “Indemnified Party”) with respect to any matter (a “Third Party Claim”) which may give rise to a claim for indemnification against any other party (the “Indemnifying Party”) under this Article VII, then the Indemnified Party shall promptly notify each Indemnifying Party thereof in writing. Failure to provide such notice within a timely fashion shall reduce the Indemnifying Party’s obligation to indemnify to the extent such failure or delay causes the Indemnifying Party to suffer damage or prejudice.

7.4.2 Any Indemnifying Party will have the right at any time to assume and thereafter conduct the defense of the Third Party Claim with counsel of his or its choice; provided, however, that the Indemnifying Party will not consent to the entry of any judgment or enter into any settlement with respect to the Third Party Claim without the prior written consent of the Indemnified Party (not to be withheld unreasonably) unless the judgment or proposed settlement involves only the payment of money damages and does not impose an injunction or other equitable relief upon the Indemnified Party; and further provided the Indemnified Party may participate at its expense in all negotiations, litigation, discovery and related matters, and to participate in the defense thereof.

7.4.3 Unless and until an Indemnifying Party assumes the defense of the Third Party Claim as provided in Section 7.4.2 above, however, the Indemnified Party may defend against the Third Party Claim in any manner he or it reasonably may deem appropriate.

7.4.4 In no event will the Indemnified Party consent to the entry of any judgment or enter into any settlement with respect to the Third Party Claim without the prior written consent of each of the Indemnifying Parties.

7.5 Notice. Any notice of claim from a party, whether a third party claim or a direct demand for indemnification, shall state and substantiate in reasonable detail the basis for such claim, and such party shall provide the other party with: (i) reasonable access to or copies of any information contained in the records of the party or of the Subsidiaries and its independent accountants and other agents that is relevant to such claim; and (ii) such information and assistance as they may reasonably request, including making employees of the Subsidiaries available on a mutually convenient basis.

7.6 Amount of Liability. The amounts for which the parties shall be liable under this Article VII of this Agreement shall be: (a) net of any tax benefit realized or realizable by the indemnified party or the Subsidiaries by reason of the facts and circumstances giving rise to such liability; (b) calculated by taking into account any tax required to be paid by such party or the Subsidiaries as a result of the accrual or receipt of any payment made pursuant to Article VII of this Agreement; and (c) net of any insurance proceeds received by such party or the Subsidiaries as a result of the facts giving rise to the right of indemnification. Each Party agrees to use commercially reasonable efforts to minimize Losses for which it may seek indemnification from any other party pursuant to this Article VII, and to minimize the amount of such indemnification obligation by reasonably pursuing all possible insurance recovery or recovery from other available sources with respect to such Losses, and nothing herein will in any way diminish each party’s common law duty to mitigate its loss.

7.7 Exclusive Remedy. THE INDEMNIFICATION PROVISIONS CONTAINED IN THIS ARTICLE VII WILL CONSTITUTE THE SOLE AND EXCLUSIVE RECOURSE AND REMEDY OF THE PARTIES FOR MONETARY DAMAGES WITH RESPECT TO ANY BREACH OF ANY OF THE REPRESENTATIONS, WARRANTIES OR COVENANTS CONTAINED IN THIS AGREEMENT OR ANY OF THE ANCILLARY AGREEMENTS OTHER THAN THOSE CONTAINED IN OR ARISING FROM ARTICLE II (EXCLUDING THE REMEDIATION). THE PROVISIONS OF THIS ARTICLE VII WILL NOT RESTRICT THE RIGHT OF ANY PARTY TO SEEK SPECIFIC PERFORMANCE OR OTHER EQUITABLE REMEDIES IN CONNECTION WITH ANY BREACH OF ANY OF THE COVENANTS CONTAINED IN THIS AGREEMENT OR ANY OF THE ANCILLARY AGREEMENTS. THE PURCHASER ACKNOWLEDGES THAT IT HAS NO RIGHT TO RESCIND THIS AGREEMENT EITHER FOR A BREACH OF CONTRACT OR FOR NEGLIGENT OR INNOCENT MISREPRESENTATION. NOTWITHSTANDING ANY

OTHER PROVISIONS OF THE AGREEMENT, THE PROVISIONS OF THIS SECTION 7.7 SHALL NOT APPLY TO EXCLUDE OR LIMIT THE LIABILITY OF SELLERS TO THE EXTENT THAT ANY CLAIM ARISES BY REASON OF ANY FRAUD OR FRAUDULENT MISREPRESENTATION OF SELLERS.
