unreasonably withheld), the Seller shall (x) operate the Business in the ordinary course of business consistent with past practice and (y) use its commercially reasonable efforts to preserve substantially intact the Acquired Assets and the Business. Without limiting the generality of the foregoing, and except as set forth on Schedule 6.1 or as otherwise contemplated by this Agreement, from the date of this Agreement to the Closing, without the prior written consent of the Purchaser (which consent shall not be unreasonably withheld or delayed), the Seller shall not: (a) subject the Acquired Assets to any Encumbrance, other than Permitted Encumbrances; (b) sell, transfer, lease, sublease, license or otherwise dispose of Acquired Assets, except for the sale, transfer, lease, sublease, license or other disposition of obsolete equipment and inventory in the ordinary course of business; (c) enter into, terminate or amend any material Contract, except in the ordinary course of business; (d) increase the compensation or benefits provided to any Transferred Employee, except for increases in the ordinary course of business; or (e) agree, whether in writing or otherwise, to do any of the foregoing set forth in clauses (a) through (d) above. Section 6.2 Books and Records; Confidentiality; Cooperation. (a) After the date hereof and prior to the Closing, the Seller shall permit the Purchaser and its authorized representatives to have reasonable access during normal business hours, upon reasonable prior notice to the Seller, to (i) inspect the physical premises and equipment of the Seller which constitute Acquired Assets and (ii) review the books and records of MSA to the extent directly relating to the Acquired Assets, the Assumed Liabilities and the Business (excluding confidential personnel and medical records), and the Seller shall furnish promptly to the Purchaser such information in the Seller's possession concerning the Acquired Assets, the Assumed Liabilities and the Business as the Purchaser may reasonably request; provided, however, that any such access shall be conducted in such a manner as not to interfere with the operation of the Business. Notwithstanding the foregoing, (i) the Seller need not disclose to the Purchaser any information which would violate applicable Law, result in a breach of attorney-client privilege or similar privilege, or violate any confidentiality or nondisclosure agreement or similar agreement or arrangement to which the Seller is a party and (ii) the Seller may redact such portions of its books and records that do not directly relate to the Acquired Assets, the Assumed Liabilities or the Business. In addition to any other inspections mentioned in this Section 6.2(a), within seventy-two (72) hours of the Closing, the Seller will permit the Purchaser and its representatives to inspect the physical premises and equipment constituting the Acquired Assets, upon reasonable notice to the Seller. (b) Until Closing, information disclosed to the Purchaser pursuant to this Agreement (including in the Seller Disclosure Schedule) shall be held as Evaluation Material (as defined in the 23

Confidentiality Agreement) and shall be subject to the Confidentiality Agreement, and the Purchaser, in accordance therewith, shall cause its Representatives (as defined in the Confidentiality Agreement) to treat as Evaluation Material all of the information provided by the Seller pursuant to this Agreement and not to use such information except in connection with the transactions contemplated hereby and otherwise in accordance with the Confidentiality Agreement. (c) Following the Closing, for so long as such information is retained by the Purchaser (which shall be for a period of at least six years unless a longer retention period is otherwise required by applicable Law or agreed to in writing), the Purchaser shall permit the Seller and its authorized representatives to have reasonable access and duplicating rights during normal business hours, upon reasonable prior notice to the Purchaser, to the pre-Closing books, records and personnel relating to the Acquired Assets, Assumed Liabilities and the Business, to the extent that such access may be reasonably required (i) in connection with the preparation of the Seller's accounting records, Tax Returns or with any audits, (ii) in connection with any suit, claim, action, proceeding or investigation relating to the Business or (iii) in connection with any regulatory filing or matter. Notwithstanding the foregoing, (i) the Purchaser need not disclose to the Seller any information which would violate applicable Law, result in a breach of attorney-client privilege or similar privilege, violate any confidentiality or nondisclosure agreement or similar agreement or arrangement to which the Purchaser is a party and (ii) the Purchaser may redact such books and records that do not directly relate to the Acquired Assets, Assumed Liabilities or the Business. (d) Following the Closing, for so long as such information is retained by the Seller (which shall be for a period of at least six years unless a longer retention period is otherwise required by applicable Law or agreed to in writing), the Seller shall permit the Purchaser and its authorized representatives to have reasonable access during normal business hours, upon reasonable prior notice to the Seller, to the retained information to the extent such access may be reasonably required (i) in connection with the preparation of the Purchaser's accounting records, Tax Returns or with any audits, (ii) in connection with any suit, claim, action, proceeding or investigation relating to the Business or (iii) in connection with any regulatory filing or matter, provided, that the Purchaser shall reimburse the Seller promptly for all reasonable and necessary out-of-pocket costs and expenses incurred by the Seller in connection with any such request; provided, further that (i) the Seller need not permit Purchaser to access any information which would violate applicable Law, result in a breach of attorney-client privilege or similar privilege, or violate any confidentiality or nondisclosure agreement or similar agreement or arrangement to which the Seller is a party and (ii) the Seller may redact such portions of its books and records that do not directly relate to the Acquired Assets, the Assumed Liabilities or the Business. The Seller shall maintain such books and records in an easily accessible format and at accessible locations. Notwithstanding the foregoing, (i) the Seller need not disclose to the Purchaser any information which would violate applicable Law, result in a breach of attorney-client privilege or similar privilege, violate any confidentiality or nondisclosure agreement or similar agreement or arrangement to which the Seller is a party and (ii) the Seller may redact such portions of the retained information that do not directly relate to the Acquired Assets, the Assumed Liabilities or the Business. (e) The Purchaser shall, and shall instruct its employees to, at the Seller's request, cooperate with the Seller as may be reasonably required in connection with the investigation and defense of any Third Party suit, claim, action, proceeding or investigation 24

relating to the Business that is brought against the Seller or any of its Affiliates at any time after the Closing; provided, however, that the Seller shall reimburse the Purchaser promptly for all reasonable and necessary out-of-pocket costs and expenses incurred by the Purchaser in connection with any such request. (f) The Seller shall, and shall instruct its employees to, at the Purchaser's request, cooperate with the Purchaser as may be reasonably required in connection with the investigation and defense of any Third Party suit, claim, action, proceeding or investigation relating to the Business that is brought against the Purchaser or any of its Affiliates at any time after the Closing; provided, however, that the Purchaser shall reimburse the Seller promptly for all reasonable and necessary out-of-pocket costs and expenses incurred by the Seller in connection with any such request. (g) Except as expressly permitted herein in Section 6.2 (c), for a period of five years following the date of this Agreement, the Seller shall neither use nor disclose any of the Trade Secrets, nor any of the Business Books and Records, for any purpose whatsoever without prior written permission of the Purchaser. Section 6.3 Provision of Corporate Records. (a) On the Closing Date, the Seller shall deliver or cause to be delivered to the Purchaser all Business Books and Records then in its possession. The foregoing shall be limited by the following specific provisions: (i) To the extent any document can be subdivided without unreasonable effort into two identical portions, such document shall be so subdivided, and the original of the portion of such document shall be provided to the Purchaser (with a copy thereof provided to the Seller). (ii) Neither party shall be required to conduct any general search or investigation of files. (iii) The Seller may retain copies of the Business Books and Records, subject to holding in confidence in accordance with Section 6.2 hereof information contained in such books and records. (iv) Neither party shall be required to deliver to the other books and records or portions thereof which are subject to confidentiality agreements which would by their terms prohibit such delivery; provided, however, if requested by the other party, such party shall use its commercially reasonable efforts to seek a waiver of such confidentiality restriction. Section 6.4 Appropriate Action; Consents; Filings. (a) Subject to Section 6.4(e) hereof, the Seller and the Purchaser shall use their reasonable best efforts to take, or cause to be taken, all appropriate action, and do, or cause to be done, all things necessary, proper or advisable under applicable Law or otherwise to consummate and make effective the transactions contemplated by this Agreement as promptly as 25

practicable, including to: (i) obtain from Governmental Entities any consents, licenses, permits, waivers, approvals, authorizations or orders required (A) to be obtained or made by the Seller or the Purchaser of any of their Affiliates to consummate the transactions contemplated by this Agreement, or (B) to avoid any action or proceeding by any Governmental Entity (including those in connection with the HSR Act and antitrust and competition laws of any other applicable jurisdiction) in connection with the authorization, execution and delivery of this Agreement and to permit the consummation of the transactions contemplated hereby to occur as soon as reasonably possible and (ii) promptly make all necessary filings, and thereafter make any other required submissions, with respect to this Agreement required under (A) the HSR Act and antitrust and competition laws of any other applicable jurisdiction, in each case, to the extent required by applicable Law or (B) any other applicable Law. The Seller and the Purchaser shall cooperate with each other in connection with the making of all filings referenced in the preceding sentence, including providing copies of all such documents to the non-filing party and its advisors prior to filing and, if requested, to accept all reasonable additions, deletions or changes suggested in connection therewith. The Seller and the Purchaser shall have the right to review in advance, and, to the extent practicable, each shall consult the other on, all the information relating to the Seller or the Purchaser, as the case may be, that appears in any filing made with, or written materials submitted to, any Third Party or any Governmental Entity in connection with the transactions contemplated by this Agreement. The Seller and the Purchaser may, as each deems reasonably advisable and necessary, designate any competitively sensitive information provided to the other under this Section 6.4(a) as "outside counsel only." Such information shall be given only to outside counsel of the recipient. In addition, the Seller and the Purchaser may redact any information from such documents shared with the other party or its counsel that is not pertinent to the subject matter of the filing or submission. Each of the Seller and the Purchaser shall bear its own costs and expenses in connection with its performance under this Section 6.4. (b) Without limiting Sections 6.4(a) or 6.4(c), but subject to Section 6.4(e), the Purchaser and the Seller shall: (i) promptly provide to the Federal Trade Commission or Department of Justice, as the case may be, such information as may be requested by the Federal Trade Commission or Department of Justice, as the case may be, and shall cause their respective officers and employees to respond to any information or other requests from the Federal Trade Commission or Department of Justice, as the case may be (including complying with requests for in-person meetings), in connection with the review by the Federal Trade Commission or Department of Justice, as the case may be, of this Agreement and the transactions contemplated hereby; and (ii) promptly submit to all applicable Governmental Entities all applications, notices and other filings and shall obtain any other approvals or consents necessary to consummate the transactions contemplated hereby and consummate the transfer from the Seller to the Purchaser of any Permits used by the Seller to conduct the Business. 26

(c) Without limiting Sections 6.4(a) or 6.4(b), but subject to Section 6.4(e), the Purchaser and the Seller shall use their respective reasonable best efforts to obtain, or to cause to be obtained, any consent, substitution, approval or amendment required to assign or transfer any Acquired Asset to the Purchaser or to novate all obligations and liabilities that constitute Assumed Liabilities or to obtain in writing the unconditional release of the Seller and its Affiliates with respect to Assumed Liabilities so that, in any such case, the Purchaser shall be solely responsible for the Assumed Liabilities. (d) In the event that any Contract (excluding Material Contracts, as defined in Section 7.3(d)) with annual payments by or to the Seller in excess of $50,000 for the year 2002 is not assigned to the Purchaser and the Purchaser has not been placed in a position to receive the benefits of such Contract as of the Closing ("Unassignable Contracts"), the Seller and the Purchaser shall adjust the Initial Purchase Price as follows: (i) In the case of an Unassignable Contract pursuant to which the Seller currently makes payments to a Third Party in return for the provision of products, goods or services by such Third Party, the Initial Purchase Price shall be reduced by the amount, if any, by which the payments to be made by the Purchaser pursuant to a replacement contract for the provision of products, goods, or services substantially similar to those provided under an Unassignable Contract exceed the aggregate payments by the Seller pursuant to such Unassignable Contract for the remainder of its term; provided, however, that, for purposes of establishing this aggregate amount, in no event shall the total amount of products, goods, or services to be purchased under such replacement contract be greater than the amount of products, goods or services required to operate the Business at its current location in the ordinary course of Business consistent with past practice, with the current mix of products. (ii) In the case of an Unassignable Contract whereby the Seller currently receives payments from a Third Party in return for the provision of products, goods or services by the Seller, the Initial Purchase Price shall be reduced by an amount equal to the net present value of the verifiable contribution margin that the Seller would have received under such Unassignable Contract. The Purchaser shall notify the Seller of such amount six months after the Closing Date. For purposes of this Section 6.4(d), if any Unassignable Contract contains a provision that allows the Third Party to such Unassignable Contract to terminate it unilaterally, without cause, any adjustments to the Initial Purchase Price set forth above will be calculated under the assumption that the Third Party to such Unassignable Contract has given notice of such termination on the Closing Date. (e) Except as expressly set forth in this Agreement (including but not limited to Article II and Article IX herein) neither the Seller or its Affiliates, on the one hand, nor the Purchaser or its Affiliates, on the other hand, shall be required to remain liable or secondarily liable or to pay any consideration to any Person or to reimburse the other for any costs or expenses incurred in connection with paragraphs (a), (b) and (c) of this Section 6.4. 27

Section 6.5 Intercompany Arrangements. Except for the agreements set forth on Schedule 6.5 hereto, all intercompany arrangements and agreements (whether written or oral, providing goods, services or joint activities) of the Seller which exclusively relate to the Business, shall be terminated and of no further force and effect after the Closing. Section 6.6 Employee Matters. (a) Prior to the Closing, the Purchaser shall offer, or cause to be offered, employment, effective as of the Closing, to at least one hundred (100) of the Employees listed on Schedule 4.8(a)(i) on an "at will" basis with the same base salary in effect for such Employee immediately prior to the Closing Date and, otherwise, subject to the Purchaser's standard terms, conditions and policies of employment and the terms hereof; provided, however, that any such employee who is absent from work immediately prior to the Closing due to vacation, holiday, illness, injury or disability, shall be offered employment in accordance with the provisions of this Section 6.6 if the employee (i) returns from vacation or holiday within thirty (30) days following the Closing, or (ii) in the case of an employee absent for illness, injury, or disability, obtains a medical release or other documentation reasonably satisfactory to the Purchaser which evidences the employee's ability to perform the essential functions of his regular work, with or without reasonable accommodation, and the employee returns to active employment with the Purchaser no later than (x) if on a short-term disability or on an approved leave of absence under the Family and Medical Leave Act of 1993, as amended ("FMLA"), the last day on which the employee may return to work under the provisions of the applicable Seller short-term disability plan or FMLA, or (y) for all other approved leaves of absence including workers' compensation leave, within six months of the Closing. Employees who accept such offers of employment from the Purchaser shall become employees of the Purchaser or its Affiliates as of the Closing or, for Employees who are absent from work on the Closing, as of the date of their return to active employment as described in the previous sentence (the "Transferred Employees"). Transferred Employees shall be offered participation in Purchaser's employee benefit plan and programs (including, without limitation, incentive compensation plans and programs) upon the same terms and conditions applicable to other similarly situated non-bargaining unit represented employees of Purchaser. Following execution of this Agreement, the Seller shall provide the Purchaser with reasonable access to the Employees, during regular business hours and in a manner that shall not interfere with the performance of such Employees' duties and responsibilities, so that Purchaser may make the offers of employment in accordance with this Section 6.6(a). (b) Transferred Employees shall receive credit for their service with Seller or any of its Affiliates (including service with any predecessor company) for all purposes under Purchaser's vacation, severance, short-term disability, and active Employee medical and life insurance plans. Except as specifically provided in this Section 6.6, service prior to the date of a Transferred Employee's transfer to employment with the Purchaser shall not be taken into account for any purpose under any other employee benefit plan, program or arrangement of Purchaser. All Transferred Employees and their eligible dependents who are participating in the Seller's medical, dental, group life insurance and other welfare benefit plans immediately prior to the Closing Date shall become participants in Purchaser's medical, dental, group life insurance and other welfare benefit plans on the date which such employee becomes a Transferred Employee (the "Transfer Date"). Purchaser agrees to credit any deductible and stop-loss amounts paid by Transferred Employee and their eligible dependents under the Seller's welfare 28

benefit plans in the calendar year in which the Closing Date occurs towards any applicable calendar year deductibles and stop-loss amounts under the Purchaser's welfare benefit plans. The Purchaser agrees to waive any waiting period, pre-existing medical condition restrictions and similar restrictions contained in Purchaser's welfare benefit plans. The Purchaser shall be solely responsible for the cost of any and all benefits to which Transferred Employee and their eligible dependents become entitled as Purchaser employees (or eligible dependents) under the terms of Purchaser's welfare benefit plans, as in effect from time to time. (c) The Seller shall have the right to terminate any and all Employees who do not accept an offer of employment with the Purchaser as of the effective date of such offer (the "Terminated Seller Employees") and the Seller shall be responsible for the severance costs related to the Terminated Seller Employees. The Purchaser shall be responsible for providing severance benefits to any Transferred Employee who is terminated on or after the Closing. (d) As of the Closing Date (or, if applicable, the Transfer Date), the Transferred Employees shall cease active participation in the MSA Retirement Savings Plan (the "Seller Defined Contribution Plan") and Purchaser will take, or cause to be taken, all action as may be necessary to cause such Transferred Employees to become eligible for participation in a defined contribution plan established or to be established by the Purchaser (the "Purchaser Defined Contribution Plan") as of such date, subject to any applicable age and service requirements. The Purchaser Defined Contribution Plan shall qualify under IRC section 401(a) and 501(a). Service of each Transferred Employee recognized under the terms of the Seller's Defined Contribution Plan for periods prior to the Transferred Employee's Transfer Date shall be credited to the Transferred Employee for all purposes (including eligibility and vesting) under the Purchaser Defined Contribution Plan. Any Transferred Employees who are participants in the Seller Defined Contribution Plan shall be one hundred percent (100%) vested in their accrued benefits and individual account balances under such Seller Defined Contribution Plan as of such employee's Transfer Date and such amounts shall be distributable to such Transferred Employees in accordance with the applicable provisions of the Plan. Transferred Employees who are participants in the Seller Defined Contribution Plan may elect direct rollover distributions from such Seller Defined Contribution Plan to the Purchaser Defined Contribution Plan. All directed rollovers between the Seller Defined Contribution Plan and any Purchaser Defined Contribution Plan will be in the form of cash. No other assets shall be transferred from the Seller Defined Contribution Plan to the Purchaser Defined Contribution Plan other than as specified herein. (e) The Purchaser and the Seller shall, to the extent possible, (i) treat the Purchaser as a "successor employer" and the Seller as a "predecessor," within the meaning of IRC Sections 3121(a) (1) and 3306(b)(1), with respect to Transferred Employees to be employed by the Purchaser for purposes of Taxes imposed under the United States Federal Unemployment Tax Act or the United States Federal Insurance Contributions Act and (ii) cooperate with each other to avoid the filing of more than one IRS Form W-2 with respect to each such Transferred Employee for the calendar year in which the Closing occurs. (f) Schedule 6.6(f) attached hereto, lists any and all Employees of the Seller who have experienced an "employment loss" (as defined under the WARN Act) within the 29

ninety (90) days prior to the date hereof, on or before the Closing Date, the Seller shall supplement such Schedule to include any Employees of the Seller who experience an "employment loss" between the date of execution of this Agreement and the Closing Date. For a period of ninety (90) days after the Closing Date, the Purchaser shall not engage in any conduct which would result in an "employment loss" (as defined under the WARN Act) for a sufficient number of employees of the Purchaser which, if aggregated with any such conduct on the part of the Seller prior to the Closing Date, would trigger the WARN Act or any similar applicable state, local or foreign law requiring notice to employees in the event of a plant closing or mass layoff. In the event that the Purchaser breaches this covenant, or a WARN Act event is triggered by Purchaser's termination of the Transferred Employees, the Purchaser shall indemnify and hold harmless the Seller and any of its Affiliates and any of their directors, officers, employees, agents, or any of their respective heirs, successors or assigns, from and against any and all claims, losses, damages, expenses, obligations and liabilities (including costs of collection, attorney's fees and other costs of defense) which they may incur with respect to Employees listed on Schedule 6.6(f), Terminated Seller Employees and Transferred Employees under the WARN Act. (g) The Seller shall be responsible for providing health care continuation coverage and notice of such coverage in accordance with IRC Section 4980B and regulations thereunder, commonly known as COBRA, to the Employees and to former employees of the Seller formerly employed in the Business, as well as their eligible dependents, with respect to any termination of coverage under the Seller's employee benefit plans. The Seller's obligations with respect to continuation coverage shall continue for the full continuation coverage period set forth in Section 602(2)(A) of ERISA and in accordance with the applicable Treasury regulations under IRC Section 4980B. To the extent that a Transferred Employee participates in any Purchaser group health plan on or after the Closing Date, the Purchaser shall assume responsibility and shall comply with all COBRA requirements with respect to such participation by such employees and any "qualified beneficiaries" (as defined in IRC Section 4980B) in accordance with IRC Section 4980B and the regulations thereunder. (h) The Seller shall be solely responsible for all obligations and liabilities accrued on or prior to the Closing Date relating to the Employees, including, but not limited to, (i) payroll and fringe benefits, (ii) earned bonuses and incentive compensation, (iii) workers' compensation and (iv) claims incurred under health plans. The Purchaser shall be solely responsible for all obligations and liabilities accrued following the Closing Date relating to the Transferred Employees, including, but not limited to, (i) payroll and fringe benefits, (ii) earned bonuses and incentive compensation, (iii) workers' compensation and (iv) claims incurred under health plans. For purposes of this Section 6.6(g), a claim shall be deemed incurred at the time services are provided. Section 6.7 Publicity. Except as otherwise required by applicable Law or applicable stock exchange requirements, prior to the Closing, neither the Purchaser nor the Seller shall, and each of them shall cause their respective Affiliates, representatives and agents not to, issue or cause the publication of any press release or public announcement with respect to the transactions contemplated by this Agreement without the express prior approval of the other party, which approval shall not be unreasonably withheld or delayed; provided, that each of the Seller and the Purchaser may make any public statement in response to questions by the press, 30

analysts, investors or those attending industry conferences or financial analyst calls, or issue press releases, so long as any such public statement or press release is not inconsistent with prior public disclosures, press releases or public statements approved by the other party pursuant to this Section 6.7 and which do not reveal non-public information about the other party. The parties hereto agree to issue a joint press release in the form which has previously been agreed to by both parties, to announce the execution of this Agreement. The parties agree to issue a joint press release, reasonably acceptable to both parties, to announce the Closing and not to issue any press release or make any other public statement inconsistent with such press release. Section 6.8 Tax Matters. (a) Periodic Taxes. All non-income Taxes and similar ad valorem obligations levied with respect to the Acquired Assets for a taxable period that includes (but does not end on) the Closing Date shall be apportioned between the Seller and the Purchaser as of the Closing Date based on the number of days of such taxable period included in the period ending with and including the Closing Date (with respect to any such taxable period, the "Pre-Closing Tax Period"), and the number of days of such taxable period beginning after the Closing Date (with respect to any such taxable period, the "Post-Closing Tax Period"). The Seller shall be liable for the proportionate amount of such Taxes that is attributable to the Pre-Closing Tax Period, and the Purchaser shall be liable for the proportionate amount of such Taxes that is attributable to the Post-Closing Period. If bills for such Taxes have not been issued as of the Closing Date, and, if the amount of such Taxes for the period including the Closing Date is not then known, the apportionment of such Taxes shall be made at Closing on the basis of the prior period's Taxes. After Closing, upon receipt of bills for the period including the Closing Date, adjustments to the apportionment shall be made by the parties, so that if either party paid more than its proper share at the Closing, the other party shall promptly reimburse such party for the excess amount paid by them. (b) Transfer Taxes. All excise, sales, use, transfer (including real property transfer or gains), stamp, documentary, filing, recordation and other similar Taxes, together with interest, additions or penalties with respect thereto resulting directly from the transaction contemplated by the Agreement ("Transfer Taxes"), shall be split evenly between the Purchaser and the Seller, with the Purchaser paying fifty percent (50%) of the Transfer Taxes and the Seller paying fifty percent (50%) of the Transfer Taxes. Any Tax Returns that must be filed in connection with Transfer Taxes shall be prepared and filed when due by the party primarily or customarily responsible under the applicable Law for filing such Tax Returns. (c) Tax Cooperation. Without duplication of Section 6.2, the Purchaser and the Seller agree to furnish or cause to be furnished to each other, upon request, as promptly as practicable, such information and assistance relating to the Business, Acquired Assets and Assumed Liabilities (including access to books and records) as is reasonably necessary for the filing of all Tax Returns, the making of any election relating to Taxes, the preparation for any audit by any Taxing Authority, and the prosecution or defense of any claims, suit or proceeding relating to any Tax. Any expenses incurred in furnishing such information or assistance shall be borne by the party requesting it. (d) The provisions of this Section 6.8 shall survive the Closing. 31

Section 6.9 Disclosure Supplements. The Seller may from time to time prior to or on the Closing Date, by notice in accordance with this Agreement and solely with the prior written consent of the Purchaser, supplement or amend the Seller Disclosure Schedule, including one or more supplements or amendments, to correct any matter that would otherwise constitute a breach of any representation, warranty or covenant contained herein. Notwithstanding any other provision hereof to the contrary, the Seller Disclosure Schedule shall be deemed for all purposes to include and reflect such supplements and amendments as of the date hereof and at all times thereafter, including the Closing Date. Section 6.10 Bulk Sale. Each of the parties to this Agreement hereby waives compliance with any bulk sales or bulk transfer laws that are applicable in respect of the transactions contemplated by this Agreement; provided, however, the Seller shall indemnify the Purchaser and hold it harmless from any claim against the Purchaser arising from non-compliance with such bulk sales laws if such claim relates to liabilities or obligations of Purchaser which are not Assumed Liabilities. Section 6.11 Contacts with Suppliers, Customers and Other Parties. Without the prior written consent of the Seller, prior to the Closing, the Purchaser shall not, and shall cause its Representatives (as defined in the Confidentiality Agreement) not to, contact any suppliers to, or customers of, the Business, any employees of the Seller or its Affiliates, counterparties (other than the Seller) to any Contracts, or any Governmental Entity (other than in connection with any filings made under the HSR Act or in connection with other consents, approvals or waivers required to be obtained by the Purchaser from Governmental Entities in connection with the transactions contemplated hereby or as required by applicable Law) in connection with or pertaining to the transactions contemplated by this Agreement. Section 6.12 Reasonable Cooperation. From and after the date hereof, the Purchaser shall reasonably cooperate with the Seller and its counsel in connection with any matters relating to the investigation into or litigation arising out of the Borane-THFB Incident; provided, however, that the Seller shall reimburse the Purchaser for all reasonable expenses incurred by the Purchaser in connection with such cooperation. Such cooperation shall include making available employees of the Business to assist the Seller in connection with any such investigations or litigation. Section 6.13 Casualty and Condemnation. If, prior to the Closing, any portion of the Real Property is damaged or any portion of the Real Property is permanently or temporarily taken by eminent domain and such events do not have a Material Adverse Effect on the Business and the Acquired Assets, then this Agreement shall remain in full force and effect and the parties shall nonetheless proceed to the Closing in accordance with this Agreement, without any abatement of the Initial Purchase Price (except for the amount of any deductible on the casualty policy covering the buildings upon the Real Property), and the Seller shall, on the Closing Date, pay to the Purchaser any sums of money collected by the Seller under the policies of casualty insurance maintained by it with respect to the Real Property, or as a condemnation award for any taking by eminent domain, after deducting any reasonable amount which the Seller may have agreed or been obligated to pay for repairs or restoration of the Real Property, or in obtaining such insurance proceeds or condemnation award, in each case including reasonable attorneys' fees and disbursements. In addition, the Seller shall assign, transfer and set over to the 32

Purchaser all of the Seller's right, title and interest in and to the net sums payable under the policies of insurance to be maintained by the Seller in connection with the Real Property not yet received by the Seller, all of the Seller's right, title and interest in and to any portion of any net condemnation award not yet received by the Seller, and all of the Seller's right, title and interest in any cause of action with respect to a casualty or to the total or partial condemnation of the Real Property. In the event that any portion of the Real Property is damaged or any portion of the Real Property is permanently or temporarily taken by eminent domain and such events have a Material Adverse Effect on the Business and the Acquired Assets, then the Purchaser may terminate this Agreement without penalty. Section 6.14 Inventory. (a) Within forty-eight (48) hours prior to the Closing, or as otherwise agreed by the parties, the parties hereto will jointly conduct a physical inventory count of the Inventory. (b) Based upon the results of the physical inventory, the inventory will be valued in accordance with GAAP (the "Inventory Value"); provided, that as to finished goods the Inventory Value shall be determined as follows: one hundred percent (100%) of the book value of the finished goods that are, as of Closing, less than one year old, seventy percent (70%) of the book value of the finished goods that are, as of Closing, one to two years old and thirty percent (30%) of the book value of the finished goods that are, as of Closing, two to three years old. The Purchaser will take title to, but pay nothing for, finished goods that are, as of Closing, more than three years old. Section 6.15 Covenant Not to Compete. Without the express prior written consent of the Purchaser, the Seller and its Affiliates shall not (i) at any time during the seven-year period immediately following the Closing Date, directly or indirectly, own, manage, control or participate in the ownership, management or control of, or be related or otherwise affiliated in any manner with, any business similar to the Business or which competes with the Business anywhere in any state or province in North America where the Purchaser shall conduct business on or after the date of this Agreement; or (ii) directly or indirectly, own, manage, control or participate in the ownership, management or control of, or be related or otherwise affiliated in any manner with, any business similar to the Business or which competes with the Business anywhere in Europe or Asia where the Purchaser shall conduct business on or after the date of this Agreement until the expiration of the maximum period of time for which this covenant not to compete shall be valid and enforceable under applicable Law; provided, that the foregoing shall not prohibit the Seller from owning, as a passive investment, five percent (5%) or less of the outstanding equity of any publicly-traded entity. Section 6.16 Non-Solicitation of Employees. (a) For a period of three years following the Closing Date, the Seller will not, directly or indirectly, solicit for employment or hire any officer, director, or employee of the Purchaser or any of its subsidiaries or divisions, except that the Seller shall not be precluded from hiring any officer, director or employee of the Purchaser or any of its subsidiaries or divisions who (i) responds to any public advertisement placed by the Seller or (ii) has been 33

terminated by the Purchaser or its subsidiaries prior to commencement of employment discussions between the Seller and such officer, director or employee.

hereof; provided, however, that nothing contained in this Section 8.2 shall relieve either party to this Agreement from liability to the other party for any willful and material breach of this Agreement. In the event this Agreement is terminated pursuant to Section 8.1, the Purchaser will redeliver all documents, work papers and other materials of the Seller relating to the transactions contemplated hereby, whether obtained before or after the execution hereof, in accordance with the terms of the Confidentiality Agreement. In addition, the Purchaser will take any and all steps reasonably required to return, if necessary, any Permits to the name of the Seller and correct the records of any Governmental Entity accordingly. ARTICLE IX SURVIVAL; INDEMNIFICATION Section 9.1 Survival of Representations and Warranties. The representations and warranties of the Seller contained in Article IV of this Agreement shall survive the Closing until the eighteen (18) month anniversary thereof; provided, however, that (a) the representations and warranties dealing with Tax matters shall survive until the expiration of the applicable statute of limitations plus three (3) months and (b) the representations and warranties set forth in Article II of the Environmental Matters Agreement shall survive, and indemnification therefor shall be, pursuant to the terms of the Environmental Matters Agreement. Notwithstanding the preceding sentence, any representation or warranty in respect of which indemnity may be sought under Article IV of this Agreement shall survive the time at which it would otherwise terminate pursuant to the preceding sentence, if notice of the inaccuracy thereof giving rise to such right of indemnity setting forth in reasonable detail the facts giving rise to such indemnity shall have been given to the party against whom such indemnity may be sought prior to such time. For purposes of this Article IX, "Indemnified Party" shall mean the party seeking indemnification and "Indemnifying Party" shall mean the party from which indemnification is sought. Section 9.2 Indemnification by the Seller. (a) Seller shall defend, indemnify and hold harmless Purchaser and its Affiliates, officers, directors, employees, agents, successors and assigns from and against any and all liabilities, losses, damages, claims, costs and expenses, interest, awards, judgments and penalties (including, without limitation, attorneys' and consultants' fees and expenses) suffered or incurred by them (a "Loss"), arising out of or resulting from: (i) the breach of any representation or warranty made by the Seller contained in Article IV of this Agreement, the Ancillary Agreements or any other documents executed in connection herewith; (ii) the Excluded Liabilities; and (iii) the Environmental Losses. 37

Section 9.3 Indemnification by the Purchaser. (a) The Purchaser shall defend, indemnify and hold harmless the Seller and its Affiliates, officers, directors, employees, agents, successors and assigns for any and all Losses, arising out of or resulting from: (i) the breach of any representation or warranty made by the Purchaser contained in Article V of this Agreement, the Ancillary Agreements or any other documents executed in connection herewith; or (ii) the Assumed Liabilities. Section 9.4 Indemnification Procedures. (a) Upon receipt by the Indemnified Party of notice from a Third Party of any action, suit, proceeding, claim, demand or assessment against such Indemnified Party which might give rise to a claim for Losses under this Section 9.4, the Indemnified Party shall promptly give written notice thereof to the Indemnifying Party indicating the nature of such claim and the basis therefor; provided, however, that failure to give such notice shall not affect the indemnification provided hereunder except to the extent the Indemnifying Party shall have been actually prejudiced as a result of such failure. Payments for Losses for Third Party claims which are otherwise covered by the indemnification obligations herein shall not be required except to the extent that the Indemnified Party has expended or simultaneously with such payment will expend out-of-pocket sums. The Indemnifying Party shall have the right, at its option, to assume the defense of, at its own expense and by its own counsel, any such matter involving the asserted liability of the Indemnified Party. If any Indemnifying Party shall, in accordance with the preceding sentence, undertake to compromise or defend any such asserted liability, it shall promptly notify the Indemnified Party of its intention to do so, and the Indemnified Party shall agree to cooperate fully with the Indemnifying Party and its counsel in the compromise of, or defense against, any such asserted liability; provided, however, that the Indemnifying Party shall not settle any such asserted liability without the written consent of the Indemnified Party (which consent will not be unreasonably withheld); provided, further, however, that the immediately preceding proviso shall not apply in the case of any settlement which releases the Indemnified Party completely in connection with such matter and which provides relief consisting solely of money damages borne by the Indemnifying Party. In any event, the Indemnified Party and its counsel shall cooperate with the Indemnifying Party and its counsel; provided, however, that the foregoing shall not prevent the Indemnified Party from taking the position that it is entitled to indemnification hereunder. (b) In the event any Indemnified Party should have an indemnification claim against any Indemnifying Party under this Agreement that does not involve a claim by a Third Party, the Indemnified Party shall promptly deliver notice of such claim to the Indemnifying Party in writing and in reasonable detail. The failure by any Indemnified Party to so notify the Indemnifying Party shall not relieve the Indemnifying Party from any liability that it may have to such Indemnified Party, except to the extent that the Indemnifying Party has been actually prejudiced by such failure. If the Indemnifying Party does not notify the Indemnified Party within 20 Business Days following its receipt of such notice that the Indemnifying Party 38

disputes such claim, such claim specified by the Indemnified Party in such notice shall be conclusively deemed a liability of the Indemnifying Party under this Section 9.4 and the Indemnifying Party shall pay the amount of such liability to the Indemnified Party on demand, or in the case of any notice in which the amount of the claim is estimated, on such later date when the amount of such claim is finally determined. If the Indemnifying Party disputes its liability with respect to such claim in a timely manner, the Indemnifying Party and the Indemnified Party shall proceed in good faith to negotiate a resolution of such dispute and, if not resolved through negotiations, such dispute shall be resolved by litigation in the appropriate court of competent jurisdiction. Section 9.5 Exclusive Remedy. Absent fraud by an Indemnifying Party, the indemnification provisions of this Article IX shall, in the case of the representations and warranties contained in Article IV of this Agreement, be the exclusive remedy following the Closing with respect to breaches thereof, and, except in the case of fraud by an Indemnifying Party, each Indemnified Party expressly waives and relinquishes, on behalf of itself, its successors and any assigns, any and all rights, claims, or remedies such person may have other than under this Article IX against any Indemnifying Party (or any Affiliate of such Indemnified Party). Section 9.6 Limitations. Notwithstanding anything to the contrary contained herein, (i) the Indemnifying Party shall not be required to provide any indemnification under Article IX of this Agreement or Article IV of the Environmental Matters Agreement with respect to any claim of inaccuracy or breach of warranty or representation under this Agreement or the Environmental Matters Agreement unless the aggregate Losses under Section 9.2(a)(i) (where the Purchaser is the Indemnified Party) or Section 9.3(a)(i) (where the Seller is the Indemnified Party) of this Agreement or Environmental Losses, as the case may be, related to one set of circumstances or multiple related circumstances for which indemnification is sought under this Agreement or the Environmental Matters Agreement, as the case may be, exceeds Forty Thousand Dollars ($40,000); (ii) the Indemnifying Party shall not have any indemnification obligations under Article IX of this Agreement or Article IV of the Environmental Matters Agreement unless the aggregate amount of Losses under Section 9.2(a)(i) (where the Purchaser is the Indemnified Party) or Section 9.3(a)(i) (where the Seller is the Indemnified Party) of this Agreement and Environmental Losses exceeds Four Hundred Thousand Dollars ($400,000) and then only to the extent of the excess of the aggregate amount of such Losses and Environmental Losses over Four Hundred Thousand Dollars ($400,000); and (iii) the maximum amount of Losses under Section 9.2(a)(i) (where the Purchaser is the Indemnified Party) or Section 9.3(a)(i) (where the Seller is the Indemnified Party) of this Agreement and Environmental Losses, in the aggregate, that may be recovered by the Indemnified Party under Article IX of this Agreement or Article IV of the Environmental Matters Agreement shall not exceed Fifty Million Dollars ($50,000,000).

All notices, claims, demands and other communications hereunder shall be in writing and shall be deemed given upon (a) confirmation of receipt of a 39

NEWS RELEASE

BASF to acquire Callery Chemical from Mine Safety Appliances Company
Transaction expands BASF inorganic chemicals line, sharpens MSA focus on core
business

MOUNT OLIVE, N.J. and PITTSBURGH, Pa., July 21, 2003 - BASF has agreed to
acquire certain assets of the Callery Chemical Division of Mine Safety
Appliances Company (AMEX:MSA), the companies announced today. BASF will pay
approximately $65 million for these assets.

The transaction will broaden BASF's inorganic chemicals portfolio and support
an expansion into important non-cyclical life science markets globally while
strengthening MSA's focus on its core safety products business, the companies
said.

The acquisition includes Callery's Evans City, Pa., site with the land and all
production facilities, business relationships, and inventory. BASF and MSA
expect to complete the transaction by the end of the third quarter of 2003,
subject to required regulatory approval, receipt of consents to assign certain
material agreements, and satisfaction of other customary closing conditions.

In 2002, Callery Chemical had sales of $30 million. Operating since 1939, it
is a leading manufacturer of boron and potassium chemicals used in
pharmaceutical products and other applications. MSA, the world's leading
manufacturer of personal protective equipment, announced in November 2002 that
it was exploring the possible sale of Callery Chemical.

"Callery is a perfect fit for BASF," said Wayne Hill, group vice president,
Intermediates and Inorganics Group, BASF Corporation. "It is an attractive
business containing specialty inorganic products that expand our inorganic
product line to one of the broadest available. With high technological
know-how, production flexibility, and the ability to develop tailor-made
solutions, this acquisition can help BASF to quickly expand inorganic product
sales in important non-cyclical markets including pharmaceutical, agrochemical
and fine chemicals."

The transaction will allow MSA to focus on driving growth in its core business
- - safety products that protect people - according to John T. Ryan III,
chairman and chief executive officer of MSA. "Callery has been a valuable part
of MSA for more than six decades and has grown significantly over the years
because of the efforts of the fine people who work there," Mr. Ryan said.
"However, Callery's business and MSA's safety equipment business have
progressed in different directions. The BASF acquisition marks the start of an
exciting new era for Callery Chemical because BASF has the resources and
marketing expertise to expand its leadership in specialty inorganic
chemicals."

Proceeds from the sale will be available to MSA for general corporate purposes
or may be distributed to shareholders. JP Morgan was the sole advisor to MSA
on this transaction.

BASF plans to continue manufacturing operations at the Evans City plant, which
is located north of Pittsburgh. Once the transaction closes, Callery will
become part of BASF's North American Inorganics business and its global
Inorganics division. MSA's Safety Products manufacturing operations at the
Evans City location will continue under a multi-year lease agreement between
the parties.

Although the pharmaceutical industry is presently Callery's largest market,
its products are also used worldwide in agrochemicals, surfactants, adhesives,
polymers, electronics, flavors, fragrances and automobiles. Callery's product
line comprises reagents for organic synthesis, including alkali metals and
alcoholates used as strong bases and catalysts, borane chemicals used for
selective reductions and hydroborations, and new boron products that support
the rapidly growing chemistry technology known as Suzuki coupling.
