NOW, THEREFORE, in consideration of the mutual representations, warranties and covenants contained herein, and on the terms and subject to the conditions set forth herein, the parties to this Agreement, intending to be legally bound, agree as follows: 7 ARTICLE 1 PURCHASE AND SALE 1.1 Purchase of Stock. (a) On the terms and subject to the conditions set forth herein, at the Closing (as defined below), Seller shall sell and deliver to Purchaser, and Purchaser shall purchase from Seller, the Stock. Seller shall sell the Stock to Purchaser, free and clear of all options, proxies, voting trusts, voting agreements, judgments, pledges, charges, escrows, rights of first refusal or first offer, mortgages, indentures, claims, transfer restrictions, liens, equities, security interests and other similar encumbrances (collectively, "Claims"). The purchase price for the Stock (the "Purchase Price") shall be Sixty-Two Million Five Hundred Thousand Dollars ($62,500,000), plus or minus (as the case may be) the Purchase Price Adjustment. (b) On the Closing Date (as defined below), all Intercompany Accounts shall be paid in full or eliminated as set forth in Section 1.4 and Purchaser shall pay $62,500,000, either (i) less (the "Holdback") Four Hundred Thousand Dollars ($400,000) (the "Holdback Amount") if the Estimated Purchase Price Adjustment is zero, or (ii) as adjusted up or down (depending on whether the Estimated Purchase Price Adjustment is a positive or negative number) by the Estimated Purchase Price Adjustment, to Seller in exchange for the Stock. Each payment of any portion of the Purchase Price shall be made by wire transfer of immediately available funds to an account of Seller or to accounts designated by it at a bank or banks designated in writing by Seller which designation shall be made at least three (3) business days before the scheduled payment date. Seller shall prepare in cooperation with Purchaser and present to Purchaser by March 15, 2001 a good faith estimate of what the "Closing Date Working Capital" would be if the Closing Date were as of February 28, 2001 (the "February Working Capital"). The "Estimated Purchase Price Adjustment" as used herein means the February Working Capital minus Eleven Million One Hundred Fifty Nine Thousand Dollars ($11,159,000). If Seller and Purchaser cannot agree to the Estimated Closing Date Working Capital in writing on or before the third day prior to the Closing Date, the Estimated Purchase Price Adjustment shall be Zero Dollars ($0). If Seller and Purchaser agree to the February Working Capital, then there shall be no Holdback Amount. 1.2 Closing. The closing of the transactions contemplated by this Agreement (the "Closing") shall take place at 10:00 a.m., Chicago, Illinois time, at the offices of Bell, Boyd & Lloyd LLC, 70 West Madison Street, Chicago, Illinois on the third business day (or, in the event the waiting period applicable to 8 the transactions contemplated under the HSR Act is terminated prior to its natural expiration, the fifth business day) following the first date on which all of the conditions in Articles 6 and 7 have been waived in writing or satisfied, or such other date as may be agreed upon by Seller and Purchaser in writing, subject, however, in each case to Article 12. The date on which the Closing occurs is hereinafter referred to as the "Closing Date."

At the Closing, the parties shall execute and deliver each document, agreement and instrument required by this Agreement to be so executed and delivered as provided in Article 8. 1.4 Settlement of Intercompany Accounts and Transfer of Cash. Seller shall cause all amounts owing from time to time under the Intercompany Accounts (whether by or in favor of the Subsidiaries) to be settled prior to the Closing Date and all cash of the Subsidiaries remaining after such settlement shall be transferred to Seller. As used herein, the term "Intercompany Accounts" shall mean those accounts maintained by Seller and Seller's Affiliates, on the one hand, and the Subsidiaries, on the other hand, in accordance with their customary practices in the ordinary course of business, in which there are reflected or recorded the amounts owed by Seller or any of its Affiliates to any of the Subsidiaries, or by any of the Subsidiaries to Seller or any of its Affiliates, attributable to intercompany transactions (including, without limitation, charges for data processing, payroll and employee benefits services, corporate office overhead, legal and/or audit services, insurance, loans and advances by any of the Subsidiaries to Seller or any of its Affiliates, and loans and advances by Seller or any of its Affiliates to any of the Subsidiaries). Seller shall contribute to the capital of the appropriate Subsidiaries all net intercompany indebtedness owed by any of the Subsidiaries to Seller or any of its Affiliates and all cash, if any, held in accounts of the Subsidiaries after such contributions shall be transferred to the Seller as of the Closing Date. As used herein: (i) an "Affiliate" is any Person which controls another Person, which such other Person controls, or which is under common control with another Person (except that, for the purposes of this Agreement, the Subsidiaries shall not be deemed to be Affiliates of Seller); (ii) "Control" means the power, direct or indirect, to direct or cause the direction of the management and policies of a Person through voting securities, contract or otherwise; and (iii) "Person" means an individual, any type of business entity (including a corporation, joint-stock company, partnership or limited liability company), any other type of legal entity (including a trust), or any governmental agency or instrumentality. 9 ARTICLE 2 ADJUSTMENTS TO PURCHASE PRICE 2.1 Balance Sheet. (a) As promptly as practicable after the Closing Date, Purchaser shall prepare and deliver to Seller a proposed combined balance sheet of the Subsidiaries as of the close of business on the Closing Date ("Proposed Balance Sheet"), in accordance with this Section 2.1. The Proposed Balance Sheet shall reflect the effects of the capital contributions required to be made pursuant to Section 1.4, shall not reflect refinancings or equity adjustments occurring on the Closing Date or Taxes to be paid by Seller under Section 10.2 and shall be prepared in accordance with United States generally accepted accounting principles ("GAAP") applied by Purchaser in a manner consistent with the accounting principles and practices applied by Seller in the preparation of the Financial Statements, with such adjustments thereto, if any, as are expressly set forth in this paragraph (a). Seller shall be permitted to have a representative present and participating in Purchaser's preparation of the Proposed Balance Sheet. Notwithstanding, or without limitation, as the case may be, of the foregoing, the parties and Arbitrating Accountants, if applicable, shall use the following procedures or principles in the preparation and determination of the Proposed Balance Sheet and Final Balance Sheet: (i) reserves and accruals shall be determined as if the date of the Proposed Balance Sheet was the last day of the fiscal year, and shall include pro rata accruals for accrued salaries, wages, bonuses, vacation pay, utilities and like items; (ii) intercompany profit in inventory shall be disregarded; (iii) the settled Intercompany Accounts and cash of the Subsidiaries shall be excluded; (iv) to the extent any sums are required to be converted to United States Currency, the rate of exchange utilized by Seller in accordance with past practice (which is based upon exchange rates stated in The Wall Street Journal) shall be employed; (v) inventories shall be determined from Seller's physical count observed by Purchaser and taking place on the previous month-end inventory and adjusted by production and sales as of the day prior to the Closing Date, and valued at the lower of cost or net realizable value, with cost being determined using the average cost methods heretofore used by K-T Clay and K-T Feldspar; (vi) subjective judgments of Seller as of December 31, 2000 (e.g., as to reserves for bad debt or litigation) shall not be altered absent a material event or change in circumstance concerning the particular matter; and (vii) Southeastern's approximately $233,000 "pre-AFE" capitalized project development shall not be classified as a current asset. Inventories in stockpiles shall be determined from surveys of such stockpiles 10 conducted through the process the Subsidiaries have used in the past. Seller shall make available to Purchaser the books, records, and personnel of the Subsidiaries (if not yet delivered to Purchaser) which Purchaser reasonably requires in order to prepare and deliver the Proposed Balance Sheet. Purchaser and Seller shall, throughout the entire period from the date of this Agreement to the date of the deliveries required by this Section 2.1, meet and discuss any and all financial and business matters relating to such process and the preparation of the Proposed Balance Sheet, and Purchaser shall make available its work papers for confidential inspection and review by Seller and Seller's accountants. Purchaser shall deliver the Proposed Balance Sheet within twenty (20) days after the Closing Date. The date of delivery of the Proposed Balance Sheet to Seller is referred to herein as the "Delivery Date." (b) Seller shall have twenty (20) days after the Delivery Date (the "Dispute Period") to dispute any of the elements of or amounts reflected on the Proposed Balance Sheet and affecting the calculation of the Purchase Price (a "Dispute"). Except as to any item on the Proposed Balance Sheet as to which Seller gives written notice of a Dispute within the Dispute Period to Purchaser (a "Dispute Notice"), the Proposed Balance Sheet shall be deemed to have been accepted and agreed to by Seller in the form in which it was delivered to Seller, and shall be final and binding upon the parties hereto. If Seller has a Dispute, Seller shall give Purchaser a Dispute Notice within the Dispute Period, setting forth in reasonable detail the elements and amounts with which it disagrees. Purchaser acknowledges and agrees that it has reviewed and is familiar with Seller's policies, methodologies and past practices regarding the accrual for reclamation obligations and that the Proposed Balance Sheet and Final Balance Sheet shall be prepared utilizing such methodology. Accordingly, Purchaser shall not assert, as a basis of any dispute with any elements of or amounts reflected on the Proposed Balance Sheet, the accrual for reclamation reflected on the Proposed Balance Sheet provided such amount was determined according to GAAP and consistently with Seller's accrual policies and past practices and no material change in circumstances at a particular reclamation site has occurred since the date of this Agreement. Within twenty (20) days after delivery of such Dispute Notice, the parties hereto shall attempt to resolve such Dispute and agree in writing upon the final content of the disputed Proposed Balance Sheet. (c) If Purchaser and Seller are unable to resolve any Dispute within the twenty (20) day period after Purchaser's receipt of a Dispute Notice, Seller and Purchaser shall promptly jointly engage the Chicago office of KPMG International (the "Arbitrating Accountant") as arbitrator, so long as KPMG International has not performed 11 accounting, tax or auditing services from such office for Purchaser, Seller, or any of their affiliates during the past three years. If KPMG International is unable or unwilling to serve as Arbitrating Accountant, the Arbitrating Accountant shall be a nationally recognized accounting firm selected promptly by agreement of Purchaser and Seller or, if they are unable to agree, by lot. The choice by lot shall be between two accounting firms which have not performed accounting, tax, or auditing services for the Purchaser, Seller, or any of their Affiliates during the past three years, one of which eligible firms shall be chosen by each Seller's and Purchaser's respective accountants, who shall jointly conduct such lottery. In connection with the resolution of any Dispute, the Arbitrating Accountant shall have confidential access to all documents, records, work papers, facilities and personnel necessary to perform its function as arbitrator. The Arbitrating Accountant's function shall be to conform the Proposed Balance Sheet to the requirements of Section 2.1. The Arbitrating Accountant shall allow Purchaser and Seller to present their respective positions regarding the Dispute and shall thereafter as promptly as possible provide the parties hereto a written determination of the Dispute, such written determination shall be final and binding upon the parties hereto, and judgment may be entered on the award. The Arbitrating Accountant shall promptly, and in any event within sixty (60) calendar days after the date of its appointment, render its decision on the question in writing and finalize the Proposed Balance Sheet. The Arbitrating Accountant may, at its discretion, conduct a conference concerning the Dispute, at which conference each party shall have the right to present additional documents, materials and other information and to have present its advisors, counsel and accountants. In connection with such process, there shall be no other hearings or any oral examinations, testimony, depositions, discovery or other similar proceedings. The Arbitrating Accountant shall determine the proportion of its fees and expenses to be paid by each of Seller and Purchaser, based on the degree to which the Arbitrating Accountant has accepted the positions of the respective parties. (d) After the Proposed Balance Sheet has been prepared and any related adjustments have been made and all Disputes resolved as provided herein, all adjustments, if any, so agreed to by the parties or required by the Arbitrating Accountant to be made with respect to the Proposed Balance Sheet shall be made. The Proposed Balance Sheet, as so revised by any such adjustments, is hereinafter referred to as the "Final Balance Sheet." 2.2 Post-Closing Adjustments. (a) The "Purchase Price Adjustment" is defined as the Closing Date Working Capital minus Eleven Million 12 One Hundred Fifty Nine Thousand Dollars ($11,159,000). The Holdback, if any, shall be terminated and Purchaser shall promptly pay Seller or Seller shall promptly pay Purchaser an amount such that Seller shall have received and Purchaser shall have paid (including through any Estimated Purchase Price Adjustment and allocation of any Holdback, as the case may be) the Purchase Price. (b) The term "Closing Date Working Capital" means an amount equal to (i) the total combined current assets of the Subsidiaries as shown on the Final Balance Sheet excluding cash, less (ii) the total combined current liabilities, current accrued expenses and current reserves of the Subsidiaries as shown on the Final Balance Sheet, excluding accrued defined benefit plan obligations. (c) Any payment or determination which is required to be made under Section 2.2(a) shall be made on the date which is three (3) business days after the Final Balance Sheet has become final, or on such other date or at such other time or place as Seller and Purchaser shall agree in writing (such date and time is hereinafter referred to as the "Post-Closing Payment Date"). All payments required to be made under this Section 2.2(b) on the Post-Closing Payment Date shall be made either through release to one party or allocated to both parties, as appropriate, of the Holdback Amount, if applicable, or by wire transfer of immediately available funds to an account of recipient at a bank designated in writing by the recipient at least three (3) business days before the Post-Closing Payment Date.

All such insurance policies are in full force and effect and neither Seller nor any of the Subsidiaries has received notice of cancellation of any such insurance policies. In the three (3) year period ending on the date hereof, neither Seller nor any of the Subsidiaries has received any written notice from, or on behalf of, any insurance carrier relating to or involving an increase in insurance rates (except to the extent that insurance risks may be increased for all similarly situated risks) or non- renewal of a policy, or requiring or suggesting material alteration of any of the Subsidiaries' respective assets, purchase of additional equipment, or material modification of any of the Subsidiaries' respective methods of doing business. The Subsidiaries shall be entitled to seek recovery under all such insurance policies held by the Subsidiaries. 4.31 Product Warranty Liabilities. None of the Subsidiaries has made any oral or written warranties with respect to the quality or absence of defects of its products or services which they respectively have sold or performed which are in force as of the date hereof, except for those warranties which are described in Schedule 4.31.

Seller has no knowledge that the percentage of products sold and services performed by any of the Subsidiaries for which warranties are presently in effect and for which warranty adjustments can be expected during unexpired warranty periods which extend beyond the Closing Date will be higher than the percentage of such products and services which the Subsidiaries have sold and performed for which warranty adjustments have been required in the past.

The furniture, fixtures, vehicles, machinery, shelving, racks, equipment, tools, dies, molds, jigs, fixtures and other tangible personal property (other than Inventory) owned or leased by any of the Subsidiaries and used in their respective operations (collectively, the "Equipment") constitutes all tangible personal property reasonably necessary in the ordinary course of business in order for the Subsidiaries to conduct their respective businesses as they have been conducted in the past. All Equipment is in operating condition and functional repair (ordinary wear and tear excepted) and any agreements related to the lease of Equipment are accounted for as operating leases, not capital leases. Schedule 4.32 contains a complete list of all leased Equipment with a cost in excess of $10,000 per year. 4.33 Y2K. To the Seller's knowledge, all of the computer hardware and Software used by the Subsidiaries in the conduct of their respective businesses (including those related to their respective facilities, equipment, manufacturing processes, quality control activities, accounting and bookkeeping, records and record keeping activities) are Year 2000 Compliant. "Year 2000 Compliant" means the ability of the hardware and Software systems to be able to accurately process date and time data (including calculating, comparing, and sequencing) from, into, and between the twentieth and twenty-first centuries, and the years 1999 and 2000 and leap year calculations. 4.34 Commercial Bribery.

Without limiting the generality of the foregoing, none of the Subsidiaries has directly or indirectly made or agreed to make (whether or not said payment is lawful) any payment to obtain, or with respect to, sales other than usual and regular compensation to its employees and sales representatives with respect to such sales. 4.35 Actions Regarding Employees. None of the Subsidiaries nor Seller has taken any actions (other than pre-existing agreements with employees referenced in Schedule 4.10 and the negotiation and execution of this Agreement and the consummation of the transactions contemplated hereby) which were calculated to dissuade any present employees, representatives or agents of any of the Subsidiaries from continuing an association with such Subsidiary after the Closing, but Seller gives Purchaser no assurance as to the continuation of any such relationship post-Closing. 4.36 Reclamation Liabilities. Schedule 4.36 describes all obligations as of September 30, 2000 of any of the Subsidiaries to reclaim any land heretofore mined by any of them or any of their predecessors, Seller's reasonable opinion as to the cost of such reclamation, the basis for calculation of such cost, the document, instrument, law, rule or regulation under which such obligation arises, and all deposits, bonds, letters of credit or other security devices outstanding with respect to all such obligations not scheduled in Schedule 4.10. 4.37 Reserve Estimates. Schedule 4.37 lists certain estimates of geological ball clay, kaolin and feldspar reserves of the Subsidiaries as of December 31, 1999. Those estimates were prepared by the Subsidiaries in good faith in the ordinary course of business in accordance with methodologies generally accepted in the ball clay, kaolin and feldspar mining industries. Seller has no knowledge that any of such estimates is overstated in any material respect, except that such reserves and methodologies may be based on market prices, costs, interest rates, and other factors known within or applicable to the mining industry which fluctuate from time to time and may have been or be affected thereby. Purchaser acknowledges that the Subsidiaries' mining operations incurred in the ordinary course consistent with past practice since December 31, 1999 have reduced such reserves. 4.38 Compliance with the Immigration Laws. Each Subsidiary is in material compliance with and has not violated the terms and provisions of the Immigration Reform and Control Act of 1986, and 53 all related regulations thereunder ("Immigration Laws"). No Subsidiary has been the subject of any inspection or investigation relating to its compliance with or violation of the Immigration Laws, nor has it been warned, fined or otherwise penalized by reason of any failure to comply with the Immigration Laws, nor is any such proceeding pending or, to the knowledge of Seller, threatened. 4.39 Representations Not Misleading. The representations and warranties of Seller in this Agreement, and all representations, warranties and statements of Seller or the Subsidiaries contained in any schedule, financial statement or exhibit, delivered pursuant hereto considered in the aggregate, do not omit to state a material fact necessary in order to make the representations, warranties or statements contained herein or therein not misleading in light of the circumstances under which they were made, provided, however, it is not the intention of the parties that this Section 4.39 obviate the qualifications and dollar limitations of the other sections of this Article 4. Furthermore, the information and access provided to Purchaser as described in Section 3.5 has been provided and prepared with reasonable care and in good faith by the Seller, and such information is accurate in all material respects. 4.40 Copies Accurate.

From and after the Closing and until the second anniversary of the Closing Date, Seller shall not, and shall cause its Affiliates to not, directly or indirectly, as a partner, stockholder, proprietor, consultant, joint venturer, investor or in any other capacity, hire or solicit to perform services (as an employee, consultant or otherwise) any Persons who are then current employees of any of the Subsidiaries or take any actions which are intended to persuade any employee of the Subsidiaries to terminate his or her association with the Subsidiaries. General solicitations of employment published in a journal, newspaper, electronic database, website, or internet posting or 69 other publication of general circulation and not specifically directed towards employees of the Subsidiaries, as the case may be ("General Solicitations"), and hiring of Persons responding to such General Solicitations (including, without limitation, employees of the Subsidiaries), shall not be deemed to constitute solicitation for purposes of this Section 9.7 and any hires in response to such General Solicitations shall not violate the provisions of this Section 9.7. 9.8 Confidentiality. From and after the Closing, Seller and its Affiliates shall keep confidential and not disclose to any other Person or use for their own benefit or the benefit of any other Person, any information regarding the Subsidiaries. The obligation of Seller and its Affiliates under this Section 9.8 shall not apply to information which: (i) is or becomes generally available to the public without breach of the commitment provided for in this Section 9.8, (ii) is required to be disclosed by law, order or regulation of a court or tribunal or government authority, or (iii) is required in connection with litigation relating to the Zemex Agreement or a Zemex Dispute; provided, however, that in the case of any proceeding before any court or other tribunal (other than a proceeding described in clause (iii)), Seller shall notify Purchaser as early as reasonably practicable prior to disclosure to allow Purchaser to take appropriate measures to preserve the confidentiality of such information. 9.9 Non-Compete. From and after the Closing and until the fifth anniversary of the Closing Date, Seller shall not and shall cause its Affiliates to not, directly or indirectly, as a partner, stockholder, proprietor, consultant, joint venturer or in any other capacity: (a) engage in, or own, manage, operate or control, or participate in the ownership, management, operation or control of, any business or entity which engages anywhere in North America or Mexico in the business of (A) mining, processing or distributing ball clay, feldspar or kaolin other than incidental to other mining activities, (B) the manufacture of ceramic bodies, or (C) manufacturing or selling any products for distribution to any customers of the Subsidiaries on the Closing Date which products compete, directly or indirectly with the Business; provided, however, that nothing herein shall prohibit Seller and its Affiliates from owning, in the aggregate, not more than five percent (5%) of any class of securities of a publicly traded entity in any of the foregoing lines of business so long as neither Seller nor any of its Affiliates participates in any way in the management, operation or control of such entity; or (b) solicit any customer of any of the Subsidiaries to purchase products or services which are regularly supplied by any of the Subsidiaries as of the Closing Date. 70 9.10 Specific Performance. Seller acknowledges that, given the nature of the business of the Subsidiaries, the covenants contained in Sections 9.7, 9.8, and 9.9 contain reasonable limitations as to time, geographical area and scope of activity to be restrained, and do not impose a greater restraint than is necessary to protect and preserve for the benefit of Purchaser the goodwill of the Subsidiaries and to protect the legitimate business interests of Purchaser. If, however, any portion of Sections 9.7, 9.8, and 9.9 is determined by any court of competent jurisdiction to be unenforceable by reason of its extending for too long a period of time or over too large a geographic area or by reason of its being too extensive in any other respect or for any other reason, it will be interpreted to extend only over the longest period of time for which it may be enforceable and/or over the largest geographical area as to which it may be enforceable and/or to the maximum extent in all other aspects as to which it may be enforceable, all as determined by such court and in such action. Seller agrees that Purchaser's remedies at law for any breach or threat of breach by Seller of the provisions of Sections 9.7, 9.8, and 9.9 will be inadequate, and that Purchaser shall be entitled to an injunction or injunctions, without the necessity for the posting of a bond or other collateral security, to prevent breaches of the provisions of Sections 9.7, 9.8 and 9.9 and to enforce specifically the terms and provisions hereof. 9.11 Retention Bonuses. Seller shall pay when due, or promptly reimburse the applicable Subsidiary for, all retention or "sale" bonuses under agreements in existence as of the Closing Date and which bonuses are payable solely by virtue of the Closing to employees of any of the Subsidiaries, it being understood that Seller shall have no liability for any cost, payment, damage, expense, or bonus arising due to a combination of the Closing and any other fact, circumstance, or event (e.g., termination by employer or employee or reduction in responsibilities, title or compensation, including any reduction of responsibility that automatically occurs as a consequence of the Closing). 9.12 Intentionally Omitted. 9.13 Retirement Plans. The Kentucky-Tennessee Clay Company Hourly Employees' Pension Plan has been, and will remain, sponsored and maintained by K-T Clay for the benefit of its eligible hourly employees and the K-T Feldspar Corporation Hourly Employee Pension Plan has been, and will remain, sponsored and maintained by K-T Feldspar for the benefit of its eligible hourly employees. Salaried employees of K-T Clay and K-T Feldspar have been covered under Seller's Hecla Mining Company Retirement Plan ("Seller's Retirement Plan"). Seller shall fully vest all affected salaried employees of K-T Clay and K-T Feldspar under Seller's Retirement Plan as of the Closing Date. Purchaser, K-T Clay and K-T Feldspar shall establish such new retirement programs as are considered desirable to cover salaried employees 71 of K-T Clay and K-T Feldspar with respect to future retirement benefit accruals on and after the Closing Date. It is the intent of Purchaser and Seller to apportion the assets and liabilities of Seller's Retirement Plan in accordance with and subject to the following provisions of this Section 9.13. (a) It is the intent of Purchaser and Seller to apportion the liabilities and assets of Seller's Retirement Plan to provide for a transfer to Purchaser's Retirement Plan (as defined below) of liabilities as of the Closing Date, and a transfer of assets within ninety (90) days of the Closing Date in an amount equal to the liabilities for retirement benefits of employees who are employees of K-T Clay and K-T Feldspar immediately after the Closing Date as measured by the Projected Benefit Obligation (as defined in Statement of Financial Accounting Standards #87), plus the Hourly Plan Underfunding Amount as defined in (d) below. The determination of the Projected Benefit Obligation shall be made using the actuarial assumptions used by Seller's actuary for plan funding purposes for the 2000 plan year, as evidenced by the actuarial report prepared by Rael & Letson and dated June 22, 2000 and a discount rate of 7% per year. Purchaser shall establish or shall cause K-T Clay and K-T Feldspar, either jointly or separately, to establish a retirement plan ("Purchaser's Retirement Plan") which shall be equal in all material respects to Seller's Retirement Plan with respect to benefits accrued as of Closing Date, including optional forms of benefits. Purchaser's Retirement Plan will assume the liability for benefits accrued under Seller's Retirement Plan prior to the Closing Date with respect to employees who are employed by K-T Clay and K-T Feldspar immediately after the Closing Date, contingent upon the receipt of the transferred assets as provided herein. Such amount to be transferred as of the Closing Date shall accrue interest at a rate of 7% per annum from the Closing Date until the date of transfer, and shall be reduced by the amount of any benefit payments (plus interest at 7%) made to or on behalf of covered employees after the Closing Date and prior to the date of transfer. In the event that Seller's Retirement Plan does not transfer the full amount specified herein, by reason of Section 414(l) of the Internal Revenue Code, or any regulations or interpretations thereunder, or by reason of any other law or regulation, or for any other reason, Seller shall pay to Purchaser the difference between the transfer amount specified herein and the amount actually transferred. (b) The amount of transferred assets as described above may be transferred in cash or in kind, to the extent a transfer in kind is approved by 72 Purchaser. As soon as practicable following the Closing Date, but not later than fifteen (15) days following the Closing Date, Seller and Purchaser shall each file Forms 5310-A, to the extent not excepted from such filing requirement by applicable regulations, in respect of Seller's Retirement Plan in the case of Seller, and Purchaser's Retirement Plan in the case of Purchaser, and shall provide the other party a copy thereof; provided, however, that the proposed transfer date referenced in the Forms 5310-A shall not be interpreted to change any provision of this Section 9.13. The actuarial calculations required hereunder shall be provided by Seller and performed by Rael & Letson ("Seller's Actuary") using the actual employee data for each plan on the Closing Date. No later than fifteen (15) days following the Closing Date, Seller shall provide to Purchaser a copy of the report of Seller's Actuary embodying the results of such calculation, and any participant data and other information needed to duplicate and confirm the calculations of the Seller's Actuary. An actuary designated by Purchaser shall, at Purchaser's expense, be entitled to confirm the accuracy of the calculations of the Seller's Actuary. In the event of a disagreement between said actuaries, the actuaries shall attempt to settle such disagreement. If the Seller's Actuary and the Purchaser's actuary are unable to settle their disagreement within forty-five (45) days following the Closing Date, the disagreement shall be settled by a third independent actuary agreed to by Seller and Purchaser, provided that such third actuary shall be limited to an amount not less than the transfer amount determined by the Seller's Actuary and not more than the amount determined by the Purchaser's actuary and further provided that such disagreement shall be settled no later than ninety (90) days following the Closing Date. Seller and Purchaser shall each pay one-half of the fee charged by any such third actuary. Seller and Purchaser shall cause any required advance notification to the IRS regarding transfers of plan assets to be made and shall cooperate to secure any approval by any government agency which is required by law for a transfer of assets and liabilities for benefits from Seller's Retirement Plan to Purchaser's Retirement Plan. (c) Purchaser shall be entitled to receive from Seller, within a reasonable time after the Closing Date and at all times thereafter, such pertinent data and information that Purchaser may reasonably require (including, but not limited to, participant and beneficiary records) to implement the requirements of this Section 9.13, to administer Purchaser's Retirement Plan and to respond to any claims, audits or examinations. Seller and Purchaser shall cooperate 73 with each other in all respects relating to this Section 9.13 and, except as otherwise set forth, shall each pay their respective expenses arising from the obligations undertaken by each pursuant to this Section 9.13. (d) For purposes of this Section 9.13, the term "Hourly Plan Underfunding Amount" shall be the excess, if any, of the sum of the Projected Benefit Obligation of the Kentucky-Tennessee Clay Company Hourly Employees' Pension Plan and the Projected Benefit Obligation of the K-T Feldspar Corporation Hourly Employee Pension Plan (the "Hourly Plans") over the total fair value of the assets of the Hourly Plans as of the Closing Date. The Projected Benefit Obligation of each plan shall be determined as of the Closing Date in accordance with Statement of Financial Accounting Standards # 87 using the actuarial assumptions used by the Seller's Actuary for funding purposes for each such plan for the 2000 plan year as evidenced by the actuarial reports prepared by Rael & Letson and dated August 18, 2000 and May 1, 2000 respectively, and a discount rate of 7% per year. 9.14 Claims under Welfare Plans.

ARTICLE 10 TAXES 10.1 In General. This Article 10 shall govern the obligation of the parties with respect to Taxes. 75 10.2 Reporting and Payment of Taxes. For all taxable periods of the U.S. Subsidiaries ending on or prior to the Closing Date, (i) the parties shall cause the U.S. Subsidiaries to join in Seller's consolidated federal income Tax Returns and, in jurisdictions requiring or permitting combined reporting with Seller or any of its Affiliates, to join in combined income Tax Returns for such jurisdictions, in accordance with current practices, and Seller shall pay the Taxes required to be paid in respect of such Tax Returns, (ii) Seller shall cause the Subsidiaries to file all other income Tax Returns to the extent such returns are required to be filed (taking into account any extensions) on or before the Closing Date and pay the Taxes required to be paid in respect of such Tax Returns, and (iii) Purchaser shall cause the Subsidiaries to file all other state income Tax Returns required to be filed on or after the Closing Date and pay the Taxes required to be paid in respect of such Tax Returns. Purchaser shall cause the Subsidiaries to file separate, combined or consolidated income Tax Returns, or shall include the Subsidiaries in its combined or consolidated income Tax Returns, for all Tax periods ending after the Closing Date and shall pay or cause to be paid all Taxes required to be paid in respect of such Tax Returns. Seller shall cause to be filed all other Tax Returns required to be filed (taking into account any extensions) by Seller on behalf of any of the Subsidiaries on or before the Closing Date, and shall pay or cause to be paid all Taxes required to be paid in respect of such Tax Returns, and Purchaser shall cause to be filed all other Tax Returns required to be filed by, or on behalf of, any of the Subsidiaries and shall pay or cause to be paid all Taxes shown to be due thereon.

Purchaser shall prepare and provide Seller with copies of each Tax Return (or the relevant portions thereof) reflecting any obligations with respect to any taxable period of any of the Subsidiaries which begins before and ends after the Closing Date ("Straddle Periods") at least thirty (30) days prior to the due date for filing such return, and Seller shall have the right to review and to grant or withhold approval of such Tax Returns (which approval shall not unreasonably be withheld). Purchaser and Seller shall attempt in good faith mutually to resolve any disagreements regarding such Tax Returns prior to the due date for filing thereof. 10.3 Certain Unpaid Taxes. To the extent an accrual on the Final Balance Sheet with respect to the Taxes for the portions of Straddle Periods ending on the Closing Date exceeds the amount of Taxes paid by the Subsidiaries on account of such Straddle Period Taxes with respect to such period, as the case may be, Purchaser shall cause the applicable Subsidiary, as appropriate, to refund the excess to Seller. To the extent such accrual is less than the amount of such Taxes paid by the applicable Subsidiary, Seller shall reimburse the applicable Subsidiary for the deficiency. Any such refund or reimbursement shall be paid concurrently with the filing of the related return relating to such Straddle Period Taxes or reflecting the effect of the Tax Election (as the case may be). 76 10.4 Allocations Relating To Taxes. Responsibilities for Taxes shall be allocated between Seller and Purchaser as follows: (a) For federal income Tax purposes, the taxable year of the Subsidiaries shall end as of the close of the Closing Date and, with respect to all other Taxes, Seller and Purchaser will, unless prohibited by applicable law, close the taxable period of the Subsidiaries as of the close of the Closing Date. Neither Seller nor Purchaser shall take any position inconsistent with the preceding sentence on any Tax Return. (b) Any allocation of income or deductions required to determine any Taxes attributable to any Straddle Period shall be made by means of an interim closing of the books and records of the Subsidiaries as of the close of the Closing Date, provided that exemptions, allowances, deductions (including, without limitation, depreciation and amortization deductions) or any Taxes (such as property, sales or similar Taxes) that are calculated on an annual or periodic basis shall be allocated between the period ending on the Closing Date and the period after the Closing Date in proportion to the number of days in each such period, excluding any impact of the Tax Election. Any disagreements regarding the allocations shall be promptly resolved in an arbitration conducted by the Arbitrating Accountant, whose decision shall be binding on the parties. (c) Any transaction occurring outside the ordinary course of business and not caused by Seller or its Affiliates on the Closing Date after the Closing, except with respect to the Tax Election, shall be treated as occurring on the day following the Closing Date. 10.5 Refunds and Credits. Seller shall be entitled to any refunds or credits for any income Taxes for periods for which Seller is responsible pursuant to this Article 10 or for which Seller must indemnify Purchaser pursuant to Article 11. Purchaser shall be entitled to any refunds of or credits for any income Taxes for periods for which Purchaser is responsible under this Article 10. Refunds for Straddle Periods shall be equitably divided between the parties in accordance with the principles in this Article 10. 10.6 Cooperation; Audits. Seller and Purchaser agree that: (a) After the Closing Date, Seller and Purchaser shall cooperate fully with each other regarding Tax matters and shall make available to the other as reasonably requested all information, records and documents relating to Taxes governed by this Agreement until the expiration of the applicable statute of limitations or extension thereof or at the conclusion of all audits, appeals or litigation with respect to Taxes relating to the Subsidiaries for such period; 77 (b) if Purchaser or any of the Subsidiaries shall receive written notice from an appropriate taxing authority of any pending examination, claims, settlements, proposed adjustments or related matters with respect to Taxes of any of the Subsidiaries that could affect Seller or any of its Affiliates, or if Seller or any of its Affiliates receives written notice from an appropriate taxing authority of any such matters that could affect Purchaser or any of the Subsidiaries, the party receiving such notice shall notify in writing the potentially affected party within ten (10) business days thereafter. The failure of any party to give the notice required by this paragraph (b) shall not impair the party's rights under this Agreement or impose any liabilities on such party except to the extent the other party demonstrates that it has been prejudiced thereby; (c) Seller shall have the right, at its expense, to control, conduct, compromise and settle any contest relating to any liability for Taxes for which Seller is solely responsible pursuant to this Article 10. If Purchaser does not consent to such compromise or settlement, however, Seller may turn over control of such contest to Purchaser, and Seller's liability for Taxes with respect to the items subject to the contest shall, in such case, be limited to the amount for which Seller would have been liable under such compromise or settlement; (d) Purchaser shall have the sole right to represent the interests of any of the Subsidiaries in all other Tax audits or administrative or court proceedings; (e) Seller shall not (unless believed required by law) file or amend any Tax Return or claim for refund or credit for taxable periods ending on or before the Closing Date to the extent that adverse consequences as to Purchaser or any of the Subsidiaries would result without Purchaser's written consent, which shall not unreasonably be withheld. Purchaser undertakes that neither it nor any of its Affiliates shall file or amend any tax return or claim for refund or credit, or settle or compromise any matter, for taxable periods ending after the Closing Date to the extent adverse consequences to Seller would result without Seller's written consent, which consent shall not unreasonably be withheld.

(d) Any claim for indemnification by Purchaser under Section 11.1 (a) shall be asserted by written notice to Seller within the appropriate Claim Period. Any matters as to which a claim has been asserted under Section 11.1(a) within the Claim Period and which are pending or unresolved before the end of the Claim Period shall continue to be covered by Section 11.1(a) until finally terminated or resolved. For the purposes of this Agreement, the relevant "Claim Period" with respect to any claim for indemnification pursuant to this Section 11.1 shall be the following: (1) With respect to any claim under Section 11.1(a)(1) (other than with respect to a breach of Sections 4.1, 4.2, 4.3 (except subparagraph 4.3(c)), 4.4, 4.5, 4.11, 4.12(a), 4.13, 4.15, 4.16, 4.17, 4.23, 4.24, 4.34 and 4.36), the Claim Period shall be the period commencing on the Closing Date and ending on the last day of the eighteenth full calendar month following the Closing Date. (2) With respect to any claim under Section 11.1(a)(1) with regard to a breach of Section 4.16 or 4.17 or any claim under Sections 11.1(a)(3), (4) or (5), the Claim Period shall be the period commencing on the Closing Date and ending on the date which is six months after the expiration of the underlying statutes of limitation.

The maximum aggregate liability of Seller with respect to claims made pursuant to the remaining provisions of Section 11.1(a) shall not exceed the amount by which (x) the Purchase Price exceeds (y) all amounts paid by Seller pursuant to the preceding sentence. In addition, Seller shall not be liable with respect to: (1) any contingent, speculative, non-quantifiable or punitive damages, or any consequential, incidental or special damages not directly resulting from the inaccuracy or breach (by way of example, the failure of title to equipment or mineral properties would entitle Purchaser to damages for the value of the equipment or mineral properties, plus reasonable attorneys' fees and expenses if applicable, but not the speculative future profits that might have been earned by the equipment or mineral properties); (2) any losses, damages, liabilities or expenses with respect to which Purchaser had a reasonable opportunity, but failed, in good faith to mitigate its loss including but not limited to, its failure (other than with respect to Environmental Indemnification Claims) to use commercially reasonable best efforts to assert non-insurance contractual rights and its failure to use commercially reasonable best efforts to recover under a policy of insurance, it being understood that this provision shall not obligate Purchaser to purchase any insurance coverage it does not currently have; or (3) except as set forth in Section 11.1(a)(10), title to Real Estate, to the extent Seller has delivered title insurance policies (or commitments therefor) conforming to the requirements of Section 8.3(n); or (4) any losses, damages, liabilities or expenses to the extent arising from or caused by actions taken by Purchaser or its Affiliates or their respective officers, directors or employees after the Closing. (f) (1) Purchaser shall not be entitled to indemnification for Damages with regard to any matter set forth in Section 11.1(a), until such time as the cumulative amount for such Damages exceeds the amount of reserves, if any, specifically allocated for such matter as set forth in the Final Balance Sheet. 84 (2) Damages sustained or incurred arising out of any misrepresentations or breaches for which indemnification is provided under Section 11.1(a)(1) shall be determined without regard to any qualification or exception relating to materiality or Material Adverse Effect contained in any such representation or warranty giving rise to the Claim for indemnity hereunder. (g) In the event that Purchaser makes a claim for indemnification under Section 11.1(a), Purchaser agrees to give Seller reasonable access to the books, records and employees of Purchaser and the Subsidiaries in connection with the matters for which indemnification is sought to the extent that Seller reasonably deems such access to be necessary in connection with their rights and obligations under this Article 11. (h) For the purposes of this Agreement, "Third Party Claim" shall mean any claim, action, suit, proceeding or like matter asserted or threatened by a party other than the parties hereto, their Affiliates, and each of their successors and permitted assigns, against any Indemnified Party as to which any Indemnified Party is subject, and which claim is reasonably expected to be subject to a party's obligations of indemnification hereunder. (i) For the purposes of clarification, any losses, damages, diminution of value of assets or properties, liabilities, demands, claims, actions or causes of action, regulatory, legislative or judicial proceedings or investigations, assessments, levies, fines, penalties, costs and expenses which have been incurred or suffered by any of the Subsidiaries and arise out of a state of facts constituting a breach of a representation and warranty of Seller shall give rise to an obligation of Seller to indemnify Purchaser pursuant to the provisions of Section 11.1(a) shall constitute Damages, and shall be deemed to have been suffered by Purchaser, provided, however, that Purchaser and Subsidiaries may not both collect for such Damages. Similarly, Purchaser may collect Damages only once for the impact of a given breach on Purchaser, the Subsidiaries, and their respective agents, representatives, employees, directors, shareholders, controllers, persons, and affiliates. 11.2 Indemnification by Purchaser. (a) Purchaser agrees to indemnify and hold harmless Seller, its directors, officers, employees, agents, and Affiliates from any loss, damage, diminution of value of assets or properties, liability and expense whatsoever (including, without limitation, reasonable attorneys' and expert witness fees and litigation expenses) resulting to Seller, its directors, officers, employees, agents, and Affiliates from: 85 (1) Any inaccuracy in any representation or warranty by Purchaser contained in this Agreement (other than in Section 3.1 or 3.2) or in any closing document delivered by Purchaser pursuant to the provisions of this Agreement, whether or not involving a Third Party Claim; (2) Any inaccuracy in any representation or warranty by Purchaser contained in Sections 3.1 and 3.2, whether or not involving a Third Party Claim; (3) Any breach of any covenant or agreement by Purchaser contained in this Agreement or in any closing document delivered by Purchaser pursuant to the provisions of this Agreement; or (4) any acts or omissions of Purchaser or any of the Subsidiaries or the operation of their respective businesses or assets for any period after the Closing Date, except for any Damages against which Purchaser is entitled to indemnification pursuant to Section 11.1 hereof. (5) any claim by OCF (or any receiver or trustee in bankruptcy for OCF) for any return of the settlement payment pursuant to that certain settlement agreement between K-T Clay and OCF dated November 17, 2000 and previously supplied to Purchaser due to a breach after the Closing Date of K-T Clay's supply contract for kaolin to OCF's Jackson, Tennessee plant dated March 16, 1998, which contract has previously been supplied to Purchaser. (b) Any claim for indemnification by Seller under Section 11.2 (a)(1), shall be asserted by written notice to Purchaser within two (2) years after the Closing Date. Any matters as to which a claim has been asserted under Section 11.2(a)(1) within two (2) years after the Closing Date and which are pending or unresolved as of the date which is two (2) years after the Closing Date shall continue to be covered by Section 11.2(a)(1) until finally terminated or resolved. With regard to any other claim under Section 11.2, any claim for indemnification by Seller shall be asserted after the Closing Date without limitation. (c) Purchaser shall not be responsible to Seller with respect to any losses, liabilities, damages or expenses as to which Seller is otherwise entitled to indemnification pursuant to Section 11.2(a)(1) unless and until (i) the aggregate amount (taking into account the $10,000 baskets in the following subsection (ii)) of such losses, liabilities, damages and expenses incurred by Seller exceeds Three Hundred Fifty Thousand Dollars ($350,000) and then only with respect to the amount that in the aggregate is in excess of Three Hundred Fifty Thousand Dollars ($350,000), and (ii) the amount of any one, individual loss, liability, damage or expense incurred by Seller exceeds Ten Thousand Dollars ($10,000). 86 11.3 Exclusive Nature of Remedies. Except for the remedy of specific performance and other equitable remedies and except to the extent that any of the parties shall have engaged in fraud or a willful breach of this Agreement, if the transactions contemplated by this Agreement are consummated the rights and remedies set forth in this Article 11 shall be the exclusive rights or remedies available to the persons to be indemnified with respect to claims against any of the parties hereto or any of their respective Affiliates, officers, directors and employees for which indemnification is authorized or provided pursuant to this Article. Such limitation shall apply notwithstanding that such claims are asserted by a cause of action or legal theory other than breach of contract. 11.4 Cooperation. Subject to the provisions of Sections 11.6, and 11.7, the party who is obligated to provide indemnification hereunder (the "Indemnifying Party") shall have the right, at its own expense, to participate in the defense of any Third Party Claim, and if said right is exercised, the parties shall cooperate in the investigation and defense of said Third Party Claim. 11.5 Subrogation. The Indemnifying Party shall not be entitled to require that any action be brought against any other Person before action is brought against it hereunder by the Indemnified Party and shall not be subrogated to any right of action until it has paid in full or successfully defended against the Third Party Claim for which indemnification is sought, but upon payment or defense shall be subrogated to any right of action, claim, contractual right, or insurance coverage applicable to the indemnification. 11.6 Third Party Claims other than Taxes and Environmental Matters. Forthwith following the receipt of notice of a Third Party Claim, other than a Third Party Claim with respect to Taxes (as to which Section 10.6 shall apply) or environmental matters (as to which Section 11.7 shall apply), the party receiving the notice of the Third Party Claim shall (i) notify the other party of its existence setting forth with reasonable specificity the facts and circumstances of which such party has received notice and (ii) if the party giving such notice is a party who is entitled to receive indemnification hereunder (an "Indemnified Party"), specifying the basis hereunder upon which the Indemnified Party's claim for indemnification is asserted. The Indemnified Party may, upon reasonable notice, tender the defense of a Third Party Claim to the Indemnifying Party. If: (a) the defense of a Third Party Claim is so tendered and within thirty (30) days thereafter such tender is accepted without qualification by the Indemnifying Party; or (b) within thirty (30) days after the date on which written notice of a Third Party Claim has been given 87 pursuant to this Section 11.6, the Indemnifying Party shall acknowledge in writing to the Indemnified Party and without qualification its indemnification obligations as provided in this Article 11 and assume the defense of the Third Party Claim; then, except as hereinafter provided, the Indemnified Party shall not, and the Indemnifying Party shall, have the right to contest, defend, litigate or settle such Third Party Claim. The Indemnified Party shall have the right to be represented by counsel at its own expense in any such contest, defense, litigation or settlement conducted by the Indemnifying Party provided that the Indemnified Party shall be entitled to reimbursement therefor only if the Indemnifying Party shall lose its right to contest, defend, litigate and settle the Third Party Claim as herein provided. The Indemnifying Party shall lose its right to defend and settle the Third Party Claim if it shall fail to diligently contest the Third Party Claim. So long as the Indemnifying Party has not lost its right and/or obligation to contest, defend, litigate and settle as herein provided, the Indemnifying Party shall have the exclusive right to contest, defend and litigate the Third Party Claim and shall have the exclusive right, in its discretion exercised in good faith, and upon the advice of counsel, to settle any such matter, either before or after the initiation of litigation, at such time and upon such terms as it deems fair and reasonable, provided that at least ten (10) days prior to any such settlement, written notice of its intention to settle shall be given to the Indemnified Party. All expenses (including without limitation attorneys' fees) incurred by the Indemnifying Party in connection with the foregoing shall be paid by the Indemnifying Party. Notwithstanding the foregoing, in connection with any settlement negotiated by an Indemnifying Party, no Indemnified Party shall be required by an Indemnifying Party to (x) enter into any settlement that does not include as an unconditional term thereof the delivery by the claimant or plaintiff to the Indemnified Party of a release from all liability in respect of such claim or litigation, (y) enter into any settlement that attributes by its terms liability to the Indemnified Party or (z) consent to the entry of any judgment that does not include as a term thereof a full dismissal of the litigation or proceeding with prejudice. No failure by an Indemnifying Party to acknowledge in writing its indemnification obligations under this Article 11 shall relieve it of such obligations to the extent they exist. If an Indemnified Party is entitled to indemnification against a Third Party Claim, and the Indemnifying Party fails to accept a tender of, or assume, the defense of a Third Party Claim pursuant to this Section 11.6, or if, in accordance with the foregoing, the Indemnifying Party shall lose its right to contest, defend, litigate and settle such a Third Party Claim, the Indemnified Party shall have the right, without prejudice to its right of indemnification hereunder, in its discretion exercised in good faith and upon the advice of counsel, to contest, defend and litigate such Third Party Claim, and may settle such Third Party Claim, either before or after the initiation of litigation, at 88 such time and upon such terms as the Indemnified Party deems fair and reasonable, provided that at least ten (10) days prior to any such settlement, written notice of its intention to settle is given to the Indemnifying Party. If, pursuant to this Section 11.6, the Indemnified Party so contests, defends, litigates or settles a Third Party Claim, for which it is entitled to indemnification hereunder as hereinabove provided, the Indemnified Party shall be reimbursed by the Indemnifying Party for the reasonable attorneys' fees and other expenses of defending, contesting, litigating and/or settling the Third Party Claim which are incurred from time to time, forthwith following the presentation to the Indemnifying Party of itemized bills for said attorneys' fees and other expenses. The failure of an Indemnified Party to notify the Indemnifying Party of a Third Party Claim, Environmental Indemnification Claim or any claim for indemnification for a breach of the representations and warranties in Section 4.16 or pursuant to Section 11.1(a)(3) or 11.1(a)(4) within the Claim Period shall not relieve the Indemnifying Party of any liability that the Indemnifying Party may have with respect to such claim except to the extent the Indemnifying Party is actually prejudiced by such failure. 11.7 Environmental Claims. Upon Purchaser becoming aware of the occurrence of any event or the existence of any state of facts in respect of which Purchaser could seek indemnification with respect to a claim for breach of any of the representations and warranties contained in Section 4.13 or a claim for indemnification under Section 11.1(a)(6) (an "Environmental Indemnification Claim"): (a) Purchaser will give to Seller prompt notice specifying in reasonable detail the basis for such Environmental Indemnification Claim; (b) Purchaser will promptly deliver to Seller copies of all draft and final environmental reports, studies, surveys, test data and reports, assessments, cost estimates and all other information available to it or any of the Subsidiaries relating to or supporting such Environmental Indemnification Claim; (c) Purchaser will permit and will cause the relevant Subsidiary to permit representatives of Seller (including advisors and consultants) to visit and inspect from time to time any of the properties to which such Environmental Indemnification Claim relates, and to enter on such properties from time to time for the purpose of conducting such environmental tests as Seller may reasonably desire with respect to such Environmental Indemnification Claim, all during normal business hours and at Seller's expense; and (d) Purchaser shall exercise reasonable efforts to furnish to Seller drafts of all proposed remediation plans prior to the date on which they are required to be 89 submitted to any applicable governmental authorities in order to give Seller a reasonable opportunity to comment on such draft plans. (e) With respect to any Environmental Indemnification Claim involving proposed action by Purchaser required by any Environmental Laws to bring a Property or any Off-Site Facility into compliance with such Environmental Laws (a "Response Action"), Purchaser shall use a reasonable alternative (the "Reasonable Alternative"). The "Reasonable Alternative" shall be limited solely to that action which (A) is, in Purchaser's reasonable judgment, necessary to achieve compliance with Environmental Laws, (B) uses, in Purchaser's reasonable judgment, the most cost- effective, commercially reasonable approach that complies with Environmental Laws, and assumes the continued use of the Property as a mining, processing or manufacturing facility, as applicable, and (C) to the extent allowed by Environmental Laws uses institutional controls, containment remedies or other remedies which do not require excavation and disposal of Hazardous Substances, unless such controls, containment or other remedy are reasonably expected to interfere with the continued use of the Property as a mining, manufacturing or processing facility, as applicable, or otherwise expected not to be reasonably practicable. Purchaser may, in selecting a Reasonable Alternative, take into consideration issues other than cost, including, but not limited to, timing, difficulty of implementation, general acceptance of the proposed technology and concerns expressed by interested parties; provided, however, that Seller shall not be liable under this Agreement for any material additional costs for a Response Action beyond the reasonably anticipated costs of a Reasonable Alternative. In no event shall the Purchaser be entitled to indemnity for any Response Action that exceeds applicable clean-up levels established by or under applicable Environmental Laws. All costs and expenses for such Response Action shall be, to the extent possible, reasonable and customary charges in the locality in which the Property or Off-Site Facility at issue is located and for the type and kind of services to be rendered. 11.8 Characterization of Indemnity Payments. Purchaser and Seller agree to treat any payment made by Seller under this Article 11 to Purchaser as an adjustment to the Purchase Price. However, in the event the IRS determines that any such payment constitutes taxable gain or income to Purchaser or any of the Subsidiaries, such payment shall be increased so that the payee receives, on an after-Tax basis, the amount which would have been received had the payment not resulted in taxable gain or income. In case payments to Purchaser through application to Purchaser's or the Subsidiaries' assets may be deducted for Tax purposes, the amount of Seller's indemnification obligation shall be reduced by the amount equal to the net saving in Taxes resulting from such deduction offer taking into account the Tax consequences to the Purchaser of the receipt of the indemnification payment. 90 11.9 Representations at Closing. For the purposes of this Article 11, each party shall be deemed to have remade all of its representations and warranties contained in this Agreement at the Closing with the same effect as if originally made at the Closing. ARTICLE 12 TERMINATION 12.1 Termination. This Agreement may be terminated and the transactions contemplated hereby may be terminated and abandoned: (a) in writing by mutual consent of the parties hereto; or (b) by Seller, if, as of March 2, 2001, Purchaser has not filed its filings under the HSR Act and Seller has so notified Purchaser of such termination by March 14, 2001, or by Seller, if, as of April 6, 2001, the closing conditions set forth in Article 7 to the performance of the obligations of the Seller shall not have been fulfilled and shall not have been waived by Seller; (c) by Purchaser, if, as of a date which is sixty (60) days after the date hereof, the closing conditions set forth in Article 6 to the performance of the obligations of Purchaser shall not have been fulfilled and shall not have been waived by Purchaser; (d) by Purchaser, if Purchaser is required or construed to be required to, in connection with the receipt of any regulatory approval or the removal or rescission of any injunction or other order, to proffer to, or agree to (i) sell or hold separate and agree to sell or to discontinue to use or limit, before or after the Closing, any assets, businesses, or interest in any assets or businesses of Purchaser, its subsidiaries, or any of the Subsidiaries other than Hecla Brazil (or to consent to any sale, or agreement to sell, or discontinuance or limitation by any Subsidiary of any of its assets or businesses) or (ii) any conditions relating to, or changes or restriction in, the operations of any such assets or businesses; or (e) by Purchaser, without regard to the accuracy or inaccuracy of any representation and warranty of the Seller regarding the Zemex Agreement, if any pending or threatened dispute or litigation between Purchaser, Seller, any of their affiliates or any of their officers, directors or representatives on the one hand and Zemex US Corporation or any of its affiliates on the other arising out of the Zemex Dispute, in the reasonable opinion of Purchaser, is expected to prevent or adversely affect the consummation of the contemplated transaction, or create any material encumbrance or restriction whatsoever relating to the ownership or operation by Purchaser of the Subsidiaries or the Business after the Closing Date. 91 12.2 Effect of Termination. In the event of any termination or abandonment of this Agreement pursuant to Section 12.1, no party (or any of its affiliates, parents, officers, directors or employees) shall have any liability or further obligation to any other party to this Agreement, except that (i) nothing herein will relieve any party from liability for fraud or any willful breach of this Agreement, (ii) Section 13.9 shall remain in full force and effect, (iii) the indemnity obligations of Seller in Section 11.1(a)(9) shall remain in full force and effect without limitation as to either the Claim Period or the maximum aggregate liability to Seller, and also without the threshold restrictions set forth in Section 11.1(c) hereof, and (iv) the obligations of the parties under the Confidentiality Letter shall remain in full force and effect. 12.3 Option Not To Purchase Certain Stock. Purchaser may, in its sole discretion, by providing written notice to Seller prior to or at the Closing, elect not to purchase any of the shares of capital stock of the Subsidiaries; provided, however, that no adjustment for such election shall be made to the Purchase Price. If Purchaser makes such election, this Agreement shall remain in full force and effect except that the shares of capital stock designated in such written election shall not be sold by Seller or purchased by Purchaser hereunder, and the representations, warranties, covenants and agreements related to such shares of capital stock shall no longer be applicable hereunder. ARTICLE 13 MISCELLANEOUS 13.1 Fees. Seller shall pay all fees and expenses due to Warrior, a division of Standard Bank London, Limited by reason of this Agreement. 13.2 Publicity. Except as otherwise required by law or applicable stock exchange rules, press releases and other publicity concerning this transaction shall be made only with the prior agreement of Seller and Purchaser. Seller and Purchaser shall use reasonable efforts to consult with each other with respect to the content of any such required press release or other publicity. 13.3 Amendments. This Agreement may be amended, modified or supplemented only by an instrument in writing executed by all of the parties hereto or, in case of an asserted waiver, signed by the party against which enforcement of the waiver is sought. 13.4 Assignment. Neither this Agreement nor any right created hereby shall be assignable by any party hereto, except that (i) at or prior to the Closing, Purchaser may assign certain of its rights and delegate certain of its duties under this Agreement to a subsidiary corporation, and (ii) after the 92 Closing, Purchaser may assign its rights and delegate its duties under this Agreement to any third party. No such assignment pursuant to (i) or (ii) above shall relieve Purchaser of any of its liabilities under this Agreement. Seller expressly acknowledges and agrees that any sale or transfer of all or substantially all of its assets (whether such sale or transfer is effected by a sale of stock of any subsidiary or sale or transfer of assets, and whether effected in one or a series of transactions and whether such sale or transfer is effected in a single transaction or in a series of related transactions, to a single acquiring entity or to one or more acquiring entities under common control with the acquiring entity) shall be at fair value in Seller's reasonable judgment and any obligations of Seller hereunder shall continue after any merger (if Seller is the survivor) or be assumed by any legal successor under applicable law (if Seller is not the survivor). 13.5 Non-Waiver. The failure in any one or more instances of a party to insist upon performance of any of the terms, covenants or conditions of this Agreement, to exercise any right or privilege in this Agreement conferred, or the waiver by said party of any breach of any of the terms, covenants or conditions of this Agreement, shall not be construed as a subsequent waiver of any such terms, covenants, conditions, rights or privileges, but the same shall continue and remain in full force and effect as if no such forbearance or waiver had occurred. No waiver shall be effective unless it is in writing and signed by an authorized representative of the waiving party. A breach of any representation, warranty or covenant shall not be affected by the fact that a more general or more specific representation, warranty or covenant was not also breached. 13.6 Binding Effect; Benefit. This Agreement shall inure to the benefit of and be binding upon the parties hereto, and their successors and permitted assigns. Nothing in this Agreement, express or implied, shall confer on any Person other than the parties hereto, and their respective successors and permitted assigns, any rights, remedies, obligations or liabilities under or by reason of this Agreement. 13.7 Notice.
