Basis of Presentation The accompanying combined financial statements include the accounts of Flex-Kleen Corporation, a Delaware corporation and a wholly-owned subsidiary of AWT Air Company ("AWT Air"), a New Jersey corporation, and Flex-Kleen Canada, Ltd., a Canadian corporation and a wholly-owned subsidiary of AWT Air. Hereafter, Flex-Kleen Corporation and Flex- Kleen Canada, Ltd. are referred to collectively as "Flex-Kleen" or "the Company". AWT Air is wholly-owned by Air & Water Technologies Corporation (AWT). All significant inter-company transactions and balances have been eliminated in the preparation of these combined financial statements. Note 2. Nature of Business and Summary of Significant Accounting Policies Nature of Business: Flex-Kleen services customers throughout the United States and Canada, providing industrial air pollution and filtration devices and related parts to its customers. The following is a summary of the Company's significant accounting policies: Revenue recognition The Company recognizes revenue when goods are shipped and when repair and maintenance services are performed. Inventories: Inventories are stated principally at the lower of cost (first in, first out method) or market and consist primarily of components and parts. Machinery and equipment: Machinery and equipment is stated at cost. Depreciation and amortization of machinery and equipment is primarily computed on the straight-line method over the estimated useful lives of the assets. The estimated useful lives are generally 5 to 10 years. Repair and maintenance costs are expensed as incurred; major renewals and betterments are capitalized. Machinery and equipment at July 31, 1998 and October 31, 1997 consists of the following: 1998 1997 ------------ ----------- Machinery and equipment $ 144,000 $ 130,000 Computer equipment 459,000 463,000 ------------ ----------- 603,000 593,000 Less: accumulated depreciation and amortization (363,000) (320,000) ------------ ----------- $ 240,000 $ 273,000 ============ =========== 6 FLEX-KLEEN CORPORATION NOTES TO FINANCIAL STATEMENTS Note 2. Nature Of Business and Summary of Significant Accounting Policies (continued) Income taxes: The Company files a federal consolidated tax return with its parent corporation AWT and subsidiaries. Accordingly, income taxes payable to (refundable from) the tax authorities are recognized on the financial statements of AWT as the taxpayer for income tax purposes. The members of the consolidated group allocate tax payments to all members of the group for the income tax reduction resulting from a member's inclusion in the consolidated return, or, the member makes payments to AWT for its allocated share of the consolidated income tax liability. This allocation represents the liability or benefit that would be reported if the Company was separately filing its tax return(s). The result of these allocations increases or reduces the amounts due to or from AWT. The Company in accordance with FASB 109 recognizes deferred tax assets on deductible temporary differences and deferred tax liabilities on taxable temporary differences. Temporary differences are the differences between the reported amounts of assets and liabilities and their tax bases. As those differences reverse, they will enter into the determination of future taxable income included in the consolidated tax returns. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some portion or all of the deferred tax assets will not be realized. Deferred tax assets and liabilities are adjusted for the effects of changes in tax laws and rates on the date of enactment. For these financial statements, the deferred tax effect is recorded as a component of amounts due to or from AWT. Use of accounting estimates: The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Note 3. Related Party Transactions Net cash transfers to AWT: As noted earlier, the Company is a wholly-owned subsidiary of AWT. As part of the cash needs management system of AWT, all available cash is swept from the Company's accounts on a regular updated basis. The Company processes payments through bank accounts which are funded by AWT as checks are presented. The net cash transfers to AWT during the year ended October 31, 1997 and the nine months ended July 31, 1998 were approximately $2,526,000 and $2,261,000, respectively. These amounts have been reflected as a reduction in available retained earnings and additional paid-in-capital in the accompanying combined financial statements. 7 FLEX-KLEEN CORPORATION NOTES TO FINANCIAL STATEMENTS Note 3. Related Party Transactions (continued) Allocation of Shared Expenses: AWT regularly incurs and pays certain expenses on the Company's behalf. All costs applicable to the Company have been included in the accompanying statements of operations. Certain common expenses and expenses incremental and proportional to the Company's operations, such as marketing, human resources, information system support, clerical and other administrative support as well as certain managerial and other costs, have been allocated to the Company and included in the accompanying statements of operations. The allocations to the Company are based on various factors, including percentage of revenue and expenses and number of employees which, in the judgment of management who control both AWT and the Company, are reasonable. General and administrative costs allocated to the Company for the nine months ended July 31, 1998 and the year ended October 31, 1997 were $266,000 and $508,000, respectively. Management believes the costs that would have been incurred had the Company existed on a stand alone basis would not have been materially different than the costs reflected in the accompanying combined statements of operations. Other Related party receivables and payables represent amounts due from or to other AWT subsidiaries and affiliates for goods and services and facility use exchanged by the Company and the related companies. There currently exists no scheduled repayment terms for these amounts and, accordingly, they have been classified as long-term in the accompanying financial statements. Note 4. Benefit Plans AWT maintains savings and retirement plans in which the Company matches a fixed percentage of each employee's contribution up to a maximum of 4% of such employee's compensation. One plan also provides for annual discretionary Company contributions which are fixed by the Board of Directors based on the performance of the applicable employee group for certain eligible employees. The expense charged to operations applicable to these plans was approximately $99,000 and $78,000 for the nine months ended July 31, 1998 and the year ended October 31, 1997, respectively. Note 5. Income Taxes The federal and state income tax provision (benefit) for the nine months ended July 31, 1998 and the year ended October 31, 1997 consist of the following: Current 1998 1997 ------------- ------------- Federal $ 605,000 $ 741,000 State 8,000 (75,000) Deferred Federal 37,000 127,000 State - - ------------- ------------- $ 650,000 $ 793,000 ============= ============= 8 FLEX-KLEEN CORPORATION NOTES TO FINANCIAL STATEMENTS Note 5. Income Taxes (continued) The difference between the income tax provision computed by applying the statutory federal income tax rate to the pretax income and the actual tax provision is as follows: 1998 1997 ------------- ------------- Statutory provision $ 577,000 $ 780,000 State income taxes 17,000 13,000 Impact of foreign operations 11,000 11,000 Non-deductible expenses 31,000 45,000 Other 14,000 (56,000) ------------- ------------- $ 650,000 $ 793,000 ============= ============= Note 6. Subsequent Event On August 12, 1998, AWT signed a letter of intent which provides for the sale of substantially all of the assets and assumption of substantially all of the liabilities of the Company for total consideration of approximately $15 million. Note 7. Commitment and Contingencies The Company is party to various lease agreements for facilities and warehouses. Rent expense for the nine months ended July 31, 1998 and the year ended October 31, 1997 was $365,000 and $650,000, respectively. Future minimum obligations under noncancellable leases with original terms in excess of one year are as follows: Years Ended October Amount ----------- ------------ 1999 $ 215,000 2000 222,000 2001 209,000 2002 200,000 2003 33,000 Thereafter ------------ $ 879,000 ============ In connection with certain financing transactions of AWT, substantially all of the assets of the Company are pledged. Note 8. Recently Issued Accounting Pronouncements Under Statement of Financial Accounting Standards No. 130 issued by the Financial Accounting Standards Board in June 1997, the Company will be required to display components of both net income and comprehensive income on the face of the financial statements along with the corresponding earnings per share amount. 9 FLEX-KLEEN CORPORATION NOTES TO FINANCIAL STATEMENTS Note 8. Recently Issued Accounting Pronouncements (continued) Comprehensive income is the change in equity during a period resulting from non-owner sources. It consists of two major items: net income and other comprehensive income. The most common components of other comprehensive income include foreign currency translation adjustments, minimum pension liability adjustments and unrealized gains and losses on available-for-sale securities. The effective date of the statement for the Company is fiscal 1999 (i.e. periods beginning after December 15, 1997). Note 9. Year 2000 Issue The Year 2000 Issue relates to whether computer systems will properly recognize and process date-sensitive information when the year changes to 2000. Systems that do not properly recognize such information could generate erroneous data or possibly fail. The Company is heavily dependent on computer processing in the conduct of substantially all of its business activities. The Company has conducted a comprehensive review of its computer systems to identify the systems that could be affected by the Year 2000 issue and believes its critical systems are Year 2000 compliant. The cost of making the systems Year 2000 compliant has not been significant to date. Due to the uncertainty regarding the direction and actions the buyer of the Company's assets may take regarding Year 2000 issues, a reasonable estimate of the costs that may be incurred to become Year 2000 compliant cannot be made. 10 Item 7.

Shareholders are the direct or indirect holders of all of Sellers' issued and outstanding capital stock. Purchasers, between them as set forth herein, desire to purchase all of the Business of Sellers. Subject only to the limitations and exclusions contained in this Agreement and on the terms and conditions hereinafter set forth, Sellers desire to sell and Purchasers desire to purchase the Business, its operations, and the assets of Sellers used therein. NOW, THEREFORE, in consideration of the recitals and of the respective covenants, representations, warranties and agreements herein contained, and intending to be legally bound hereby, the parties hereto hereby agree as follows: 1 ARTICLE 1 Purchase and Sale 1.1 Purchase and Sale. At the Closing hereunder (as defined in Section 2.1 hereof) and except for the Excluded Assets (as defined by and set forth in Section 1.1.2 hereof), Purchasers, upon and subject to the terms and conditions of this Agreement and in reliance upon the representations, warranties, covenants and agreements of Sellers and Shareholders herein contained, agree to purchase from Sellers, and Sellers, upon and subject to the terms and conditions of this Agreement and in reliance upon the representations, warranties, covenants and agreements of Purchasers, agree to sell, grant, convey, assign, transfer and deliver to Purchasers, as between them as set forth in Section 1.2 hereof, all right, title and interest of Sellers in and to (a) the Business as a going concern, (b) the names "FLEX-KLEEN CORPORATION" and "FLEX-KLEEN CANADA LIMITED" and all variations thereof and all goodwill associated therewith, and (c) all of the assets, properties and rights of Sellers constituting the Business or used therein, of every kind and description, real, personal and mixed, tangible and intangible, wherever situated (which Business, name, goodwill, assets, properties and rights are herein sometimes called the "Assets"), free and clear of all mortgages, liens, pledges, security interests, charges, claims, restrictions and encumbrances of any nature whatsoever (collectively "Liens"), except Permitted Liens (as defined in Section 3.1.11 hereof). In addition, AWT Air at Closing shall assign and transfer to Purchasers all of its right, title and interest in any Confidentiality Agreement (as defined in Section 1.1(e) below) executed by AWT Air and any employee, consultant, customer or vendor of Sellers; provided, however, that the foregoing shall not be deemed to preclude Sellers or Shareholders from enforcing the provisions of such Confidentiality Agreements with respect to information matters or events arising on or prior to the Closing Date. 1.1.1 Included Assets. The Assets shall exclude only those assets expressly set forth in Section 1.1.2 hereof, and shall include without limitation all of the tangible and intangible assets, properties and rights of Sellers used directly or indirectly in the conduct of, or generated by or constituting, the Business, both in the United States, Canada, and in any other locations, as of the Effective Date (as hereafter defined in Section 2.6), including, without limitation, the following: (a) all machinery, equipment, office equipment and systems, tools, vehicles, furniture, furnishings, partitions, plant equipment, fixtures, leasehold improvements, molds, dies, goods, and other tangible personal property; 2 (b) all cash or cash equivalents of Sellers, in transit, in hand or in bank accounts, regardless of whether maintained in the name of Sellers or Shareholders, including all cash generated by the Business after the Effective Date; (c) all prepaid items, unbilled costs and fees, and accounts, notes and other receivables; (d) all supplies, inventories, finished goods, spare parts, replacement parts, materials, raw materials, work in process, goods, and office and other supplies including packaging material and cartons; (e) to the extent permitted by applicable law, all rights under any agreement, non-disclosure or confidentiality agreement (each a "Confidentiality Agreement"), Contract (as defined in Section 3.1.15 hereof), contract, agreement with vendors and suppliers, lease, plan, instrument, registration, license, certificate of occupancy, other permit or approval of any nature, or other document, commitment, arrangement, undertaking, practice or authorization; (f) all rights under any patent, trademark, service mark, trade name, business name, trade dress, logo or copyright, whether registered or unregistered, and any applications therefor; (g) all technologies, methods, formulations, data bases, trade secrets, know-how, inventions and other intellectual property used in the Business or under development; (h) all computer software including but not limited to the EMS Accounting System (including documentation and related object and source codes, if presently available to Sellers); (i) all information, files, records, documents, sales and product literature, advertising mechanicals and photographs, advertising text and copy, advertising, marketing and promotional materials, demonstration samples, product models, and any other usual sales materials, engineering drawings, technical data, operational manuals, books and records, data, plans, contracts and recorded knowledge, including customer, vendor, representative, distributor and supplier lists, related to the foregoing; (j) all business telephone numbers and mailing addresses, including all post office box numbers, for and owned by the Business; 3 (k) all rights or choses in action arising out of occurrences before or after the Closing, including without limitation all rights under express or implied warranties relating to the Assets; (l) to the extent not covered above, all claims and rights under contracts, agreements, contract rights, leases, license agreements, franchise rights, policies, purchase and sale orders, quotations, executory commitments, instruments, arrangements and understandings of Sellers to which either Seller is a party, including but not limited to any security deposits; and (m) to the extent not covered above, all assets and properties reflected on the Effective Date Pro Forma Balance Sheet (as defined in Section 3.1.6 hereof). 1.1.2 Excluded Assets. Notwithstanding the foregoing, the Assets shall not include any of the following (collectively the "Excluded Assets" and each an "Excluded Asset"): (a) the corporate seals, certificates of incorporation, minute books, stock books, tax returns, books of account or other records having to do with corporate organization of Sellers; (b) the rights which accrue or will accrue to Sellers under this Agreement; (c) the rights to any of Sellers' claims for any federal, Canadian, Provincial, state, local, or other foreign tax refunds or credits relating to periods prior to the Effective Date, plus the rights to any of Sellers' claims for any federal, Canadian, Provincial, state, local or other foreign income tax refunds or credits relating to periods prior to the Closing Date; (d) any receivable or inter-company indebtedness due from either of the Shareholders or other affiliate of Sellers as of the Effective Date; (e) assets disposed of in the ordinary course of business between the Effective Date and the Closing Date in accordance with the provisions of this Agreement; (f) Sellers' "CARAT" accounting software; 4 (g) any insurance policy of Seller, and any right of Sellers under any policy of insurance, including any proceeds payable or paid thereunder, for claims arising prior to the Effective Date; (h) any trademark or service mark not used in the Business, or other tangible or intangible asset or right set forth on Exhibit 1.1.2 hereof; (i) assets associated with employees or employee benefit plans prior to the Closing Date; (j) the leases of Sellers for the facilities in Sharpsburg, North Carolina and Richmond Hill, Ontario; (k) the capital stock of Sellers; (l) assets of Flex-Kleen Canada which do not primarily relate to the Business, including but not limited to Flex-Kleen Canada's right to payment from Stone Container (Canada), Inc; and (m) any asset or item set forth on Schedule 1.1.2 hereof. 1.2 Purchase As Between Met-Pro and Met-Pro Canada. At Closing, the Assets shall be acquired by, and transferred and conveyed to, as between the Purchasers as follows: (a) all of the Assets that are used by Flex-Kleen Canada in the Business shall be acquired by, and transferred and conveyed to, Met-Pro Canada; and (b) all other Assets shall be acquired by, and shall be transferred and conveyed to, Met-Pro, except that at or prior to Closing, Met-Pro may assign its right hereunder to any wholly-owned subsidiary of Met-Pro; provided, however, that Met-Pro shall be solely liable for any performance required of it hereunder, notwithstanding any such assignment. 1.3 The Purchase Price. 1.3.1 Purchase Price. The purchase price (the "Purchase Price") to be paid hereunder by Purchasers shall be in the amount of $15,000,000 (fifteen million dollars) cash, which amount shall be subject to adjustment as provided for by Section 1.3.2 hereof. 5 1.3.2 Adjustment at Closing to Purchase Price. The Purchase Price shall be adjusted at Closing as follows: (a) The Purchase Price shall be reduced by the amount, if any, by which the Pro Forma Net Equity (as hereafter defined) on the Effective Date Pro Forma Balance Sheet is less than $2,200,000. No adjustment to the amount of the Purchase Price shall be made to the extent to which such Pro Forma Net Equity on the Effective Date Pro Forma Balance Sheet shall exceed $2,200,000. For purposes of this Agreement, "Pro Forma Net Equity" shall mean the book value of the Assets recorded on the Effective Date Pro Forma Balance Sheet, net of and minus the liabilities recorded on the Effective Date Pro Forma Balance Sheet; and (b) The Purchase Price shall be reduced by the product, if any, determined by multiplying (x) the amount by which the EBITDA (as hereafter defined) for the nine months ending July 31, 1998 as determined from the July 31, 1998 Financial Statements (hereafter defined in Section 3.1.6 hereof) is less than $1,650,000, (y) by five (5). The maximum amount of reduction in the Purchase Price pursuant to this adjustment shall be $500,000. No adjustment to the amount of the Purchase Price shall be made to the extent to which such EBITDA for the nine months ending July 31, 1998 on the July 31, 1998 Financial Statements shall exceed $1,650,000. For purposes of this Agreement, "EBITDA" shall mean earnings on the July 31, 1998 Financial Statements before interest, taxes, depreciation, and amortization, determined in accordance with U.S. generally accepted accounting principles ("GAAP"), consistently applied. (c) The sum of the reductions, if any, to the Purchase Price provided by this Section 1.3.2 shall be referred to in this Agreement as the "Purchase Price Closing Adjustment." 1.3.3 Payment of Purchase Price. On the Closing Date, Purchasers shall pay (i) to Sellers, on account of the Purchase Price, $14,500,000 (fourteen million five hundred thousand dollars), less the amount of the Purchase Price Closing Adjustment (such net amount, the "Sellers Closing Payment"), payable by wire transfer of immediately available funds to such account as Sellers shall designate, and (ii) to the Escrow Agent (the costs and charges of which shall be shared equally between Sellers and Purchasers) under an Escrow Agreement substantially in the form attached hereto as Exhibit 1.3.3 (the "Escrow Agreement"), on account of the Purchase Price, the sum of $500,000 (five hundred thousand dollars) (the "Escrow Closing Payment"; and together with the Sellers Closing Payment, the "Closing Payment"). 6 1.3.4 Allocation of Purchase Price. (a) As soon as practicable after the Closing Date, Sellers shall deliver to Purchasers a statement (the "Allocation Statement") setting forth the allocation of the Purchase Price, plus or minus, as the case may be, and to the extent properly taken into account under Section 1060 of the Internal Revenue Code of 1986, as amended (the "Code"), the Assumed Liabilities, any Purchase Price Closing Adjustment pursuant to Section 1.3.2 hereof, and any Closing Cash Flow Reimbursement Payment and any Post-Closing Cash Flow Reimbursement Payment pursuant to Sections 1.3.5(a) and 1.3.5(b) hereof, respectively, amongst the Assets and the covenant not to compete contained in Section 6.6 hereof. The Allocation Statement shall reflect the allocation set forth on Schedule 1.3.4 hereto, plus or minus any adjustments to the Purchase Price for the Post-Closing Cash Flow Reimbursement Payment (to the extent properly taken into account under Section 1060 of the Code). (b) Purchasers shall have a period of fifteen (15) calendar days after the delivery of the Allocation Statement to present in writing to Seller any objections that Purchasers may have to the calculation and allocation set forth in the Allocation Statement. Unless Purchasers timely object, the Allocation Statement shall be binding upon the parties without further adjustment. (c) If Purchasers shall raise any objections within such fifteen (15) calendar day period, Purchasers and Sellers shall negotiate in good faith and use their best efforts to resolve such dispute. If the parties fail to agree within five (5) calendar days after Purchasers' delivery of their objections, then each party may calculate and allocate the Purchase Price (for purposes of Section 1060 of the Code) as it shall determine; provided, however, that the $50,000 allocated in Schedule 1.3.4 to the covenant not to compete provided for in Section 6.6 hereof and the absence in Schedule 1.3.4 of any allocation to goodwill as a component of the Assets and Business of Flex-Kleen Canada shall not vary from that provided for in Schedule 1.3.4. (d) If the Allocation Statement is finally agreed upon as provided for hereby, Sellers and Purchasers agree to (i) calculate and report, and to cause their affiliates to calculate and report, an allocation of such Purchase Price (with adjustments as described above) amongst the Assets and the covenant not to compete in a manner entirely consistent with the agreed-to Allocation Statement, (ii) act in accordance with the Allocation Statement in the preparation and filing of all Tax returns and elections (including, without limitation filing Form 8594 with their Federal income Tax returns for the taxable 7 year that includes the Effective Date) and in the course of any Tax audit, Tax review or Tax litigation relating thereto and (iii) take no position and cause their affiliates to take no position inconsistent with the Allocation Statement for U.S. federal and state and Canadian and Provincial income Tax purposes. (e) Not later than 30 days prior to the filing of their respective Forms 8594 relating to this transaction, each party shall deliver to the other party a copy of its Form 8594. (f) The parties acknowledge and agree that any adjustment to the Allocation Statement for the Closing Cash Flow Reimbursement Payment and the Post-Closing Cash Flow Reimbursement Payment contemplated by Section 1.3.4(a) hereof is for tax reporting purposes only, and shall not be considered an adjustment for financial reporting purposes, and that nothing contained in this Section 1.3.4 or in Sellers' or Purchasers' Form 8594 shall be deemed to in any way alter the intent or intended effect of Section 2.6 or Section 6.13(b) hereof. 1.3.5 Reimbursement for Cash Outlays between the Effective Date and the Closing Date. (a) At Closing, there shall be a reimbursement for the Cash Flow (as hereafter defined) of the Business during the period beginning with the Effective Date and ending on September 25, 1998, in the amount set forth on Schedule 1.3.5 hereto, payable by wire transfer of immediately available funds to such account as Purchasers, if the Cash Flow shall be a positive number, or Sellers, if the Cash Flow shall be a negative number, shall designate (the "Closing Cash Flow Reimbursement Payment"). For purposes of this Section 1.3.5, "Cash Flow" of the Business shall mean the difference obtained by subtracting (i) net cash transfers, payments, contributions or infusions made by Shareholders or any of their affiliates to Sellers which are in the nature of loans, capital contributions or similar advances to Sellers, from (ii) net cash transfers, payments, distributions or disbursements made by Sellers to Shareholders or any of their affiliates which are in the nature of loans, dividends, distributions or similar advances to Shareholders or their affiliates or withdrawals from Sellers. (b) After Closing, there shall be a reimbursement for the Cash Flow of the Business during the period between September 26, 1998 and ending on the Closing Date (the "Post-Closing Cash Flow Reimbursement 8 Payment"), as follows: (i) Within twenty (20) calendar days following the Closing Date, Sellers shall deliver to Purchasers a pro forma unaudited Cash Flow statement of the Business for the period beginning with September 26, 1998 and ending on the Closing Date (the "Closing Pro Forma Cash Flow Statement"). In preparing the Closing Pro Forma Cash Flow Statement, Sellers shall utilize the same procedures and methodology utilized in the determining the amount of the Closing Cash Flow Reimbursement Payment reflected in Schedule 1.3.5 hereof. (ii) If Purchasers disagree with Sellers' Closing Pro Forma Cash Flow Statement delivered pursuant to Section 1.3.5(b)(i) hereof, Purchasers may, within twenty five (25) calendar days after delivery of the Closing Pro Forma Cash Flow Statement, deliver a notice to Sellers disagreeing with such calculation and setting forth Purchasers' calculation of such amount. Any such notice of disagreement shall specify those items or amounts as to which Purchasers disagree, and Purchasers shall be deemed to have agreed with all other items and amounts contained in the Closing Pro Forma Cash Flow Statement. (iii) The "Final Closing Pro Forma Cash Flow Statement" shall be (A) the Closing Pro Forma Cash Flow Statement if Purchasers do not notify Sellers of any disagreement therewith within such twenty-five (25) calendar-day period and (B) if Purchasers notify Sellers in writing of any disagreement with such Closing Pro Forma Cash Flow Statement, such Closing Pro Forma Cash Flow Statement as adjusted or corrected in accordance with the resolution of such disagreement, either by agreement of Sellers or Purchasers or by an internationally recognized firm of independent public accountants as to which Sellers and Purchasers shall mutually agree (the "CPA Firm"), as the case may be. (iv) Purchasers and Sellers shall negotiate in good faith to resolve any disagreements raised by Purchasers' disagreement notice, but if Purchasers and Sellers are unable to resolve all of their disagreements with respect to the determination of any of the disputed items within ten (10) calendar days following receipt of Purchasers' disagreement notice, they shall proceed to refer their remaining disagreements to the CPA Firm, which shall, acting as experts and not as arbitrators, determine, only with respect to 9 the remaining differences so submitted, whether and to what extent, if any, the Closing Pro Forma Cash Flow Statement requires correction or adjustment. The parties shall instruct the CPA Firm to deliver its written determination to Purchasers and Sellers no later than the twentieth calendar day after the remaining differences underlying Purchasers' notice are referred to the CPA Firm. The cost of such review and report shall be borne (A) by Sellers if the difference between the Final Closing Pro Forma Cash Flow Statement and Closing Pro Forma Cash Flow Statement as set forth in Sellers' calculation of the Closing Pro Forma Cash Flow Statement delivered pursuant to Section 1.3.5(b)(i) hereof is greater than the difference between the Final Closing Pro Forma Cash Flow Statement and the Closing Pro Forma Cash Flow Statement as set forth in Purchasers' calculation of the Closing Pro Forma Cash Flow Statement delivered pursuant to Section 1.3.5(b)(i) hereof, (B) by Purchasers if the first such difference is less than the second such difference, and (C) otherwise equally by Purchasers and Sellers. (v) If the Final Closing Pro Forma Cash Flow Statement reflects a negative cash amount (i.e., that during the period between October 1, 1998 and the Closing Date, the amount of cash infused into the Business by Sellers or Shareholders exceeded the amount withdrawn by Sellers or Shareholders), then Purchasers shall pay Sellers such negative amount; and if the Final Closing Pro Forma Cash Flow Statement reflects a positive cash amount (i.e., that during the period between October 1, 1998 and the Closing Date, the amount of cash withdrawn by Sellers or Shareholders from the Business exceeded the amount infused by Sellers or Shareholders into the Business), then Sellers shall pay Purchasers such positive amount, in each case, by wire transfer of immediately available funds to such account as the recipient shall designate, within five (5) calendar days of finalizing the Final Closing Pro Forma Cash Flow Statement pursuant to this Section 1.3.5, provided, however, that if upon Purchasers completing their review of the Closing Pro Forma Cash Flow Statement, there is any amount owning hereunder by either party to the other party that is not in dispute by the parties, Purchasers or Sellers, as applicable, shall pay such undisputed amount to the other party promptly (within five (5) calendar days of Purchasers' completion of such review). 10 (c) To the extent to which this Agreement elsewhere specifically provides for reimbursement of Sellers for certain expenses of the Business beginning with the Effective Date, including, without limitation, as set forth in Sections 5.5(a) and 5.5(c) hereof, such amounts shall not be included as an expense of the Business for purposes of this Section 1.3.5. In addition, in determining the Cash Flow of the Business for the period beginning with the Effective Date, the parties shall give effect to the provisions of this Agreement, including without limitation Section 6. 13(a) and Section 7.3 hereof. 1.4 Assumption of Certain Liabilities; Excluded Liabilities. 1.4.1 Assumed Liabilities. Upon the terms and subject to the conditions of this Agreement including but not limited to Purchasers' right to indemnity under Section 4.1 hereof, Purchasers agree, effective at the time of the Closing, to assume all debts, obligations, contracts and liabilities of Sellers of any kind, character or description relating to or arising out of the conduct of the Business (collectively the "Assumed Liabilities"), except for the Excluded Liabilities (as defined by and set forth in Section 1.4.2 hereof), including without limitation the following: (a) all liabilities set forth on the Effective Date Pro Forma Balance Sheet and all liabilities incurred after the Effective Date to the extent not satisfied prior to the Closing Date; (b) all liabilities and obligations of Sellers arising under the Contracts (as defined in Section 3.1.15 hereof); (c) by way of an assignment of such leases, all liabilities and obligations of Sellers arising after the Effective Date under the real property lease for the offices occupied by Flex-Kleen in Itasca, Illinois (the "Itasca Lease"); (d) all warranty liabilities and obligations relating to any products manufactured or sold by the Business on or prior to the Closing Date (exclusive of any product liability claims); (e) except as set forth in Section 1.4.2 hereof, all liabilities or obligations relating to employee benefits or compensation arrangements existing on or prior to the Effective Date, to the extent such obligations are reserved for on the Effective Date Pro Forma Balance Sheet, with respect to any employee of the Business who is employed by Purchasers as of the Closing Date; and 11 (f) the obligations of Sellers and Aqua Alliance under that certain Transitional Services Agreement dated as of July 23, 1998 between Aqua Alliance and Hamon & Cie (International) S.A. ("Hamon"), only with respect to the provision to Hamon and/or its subsidiaries of office space at Itasca, Illinois, warehouse space and services at Sharpsburg, North Carolina and the EMS Inventory Accounting System described in items 2, 6 and 7 of Schedule A thereof. 1.4.2 Excluded Liabilities. Notwithstanding any provision in this Agreement including but not limited to Section 1.4.1 hereof or any other writing to the contrary, Purchasers at Closing shall assume only the Assumed Liabilities and shall not assume any other liability or obligation of Sellers of whatever nature, whether presently in existence or arising hereafter. All such other liabilities and obligations shall be retained by and remain obligations and liabilities of Sellers (all such liabilities and obligations not being assumed being herein referred to as the "Excluded Liabilities" and each an "Excluded Liability"), and, notwithstanding anything to the contrary in this Section 1.4, none of the following shall be Assumed Liabilities for the purposes of this Agreement: (a) any liability or obligation for any Tax (as hereafter defined) incurred prior to the Effective Date together with any liability or obligation under Section 6.13(a) hereof; provided, however, that Transfer Taxes (as defined by Section 7.2 hereof) incurred in connection with the transactions contemplated by this Agreement shall be paid in the manner set forth in Section 7.2 hereof. For purposes of this Agreement, "Tax" means (i) any net income, alternative or add-on minimum tax, gross income, gross receipts, sales, use, ad valorem, value added, transfer, franchise, profits, license, registration, recording, documentary, conveyancing, gains, withholding on amounts paid to or by any Seller, payroll, employment, excise, severance, stamp, occupation, premium, property, environmental, windfall profit, goods and services, capital, Canada Pension Plan, custom duty or other tax, governmental fee or other like assessment or charge of any kind whatsoever, together with any interest, penalty, addition to tax or additional amount imposed by any governmental authority responsible for the imposition of any such tax (domestic or foreign), or (ii) liability for the payment of any amounts of the type described in (i) as a result of being party to any agreement or any express or implied obligation to indemnify any other person;

Except as set forth in Section 3.1.26 of the Disclosure Schedule: (a) Flex-Kleen Canada is not a non-resident of Canada with the meaning of Section 116 of the Income Tax Act of Canada.

EXCEPT FOR THE REPRESENTATIONS AND WARRANTIES OF SELLERS SET FORTH IN SECTION 3.1 HEREOF, PURCHASERS AGREE AND ACKNOWLEDGE THAT THE PURCHASED ASSETS ARE BEING SOLD "AS IS," AND PURCHASERS AGREE TO ACCEPT THE PURCHASED ASSETS AND THE BUSINESS IN THE CONDITION THAT THEY ARE IN ON THE CLOSING DATE WITHOUT RELIANCE UPON ANY OTHER REPRESENTATIONS OR WARRANTIES, EXPRESS OR IMPLIED, MADE BY OR ON BEHALF OF OR IMPUTED TO SELLERS OR THEIR AFFILIATES. Without limiting the generality of the foregoing, Purchasers acknowledge that Sellers and their affiliates make no representation or warranty with respect to (a) any projections, estimates or budgets delivered to or made available to Purchasers of future revenues, future results of operations (or any components thereof), future cash flows or future financial condition (or any component thereof) of the Business or the future business and operations of the Business or, (b) except for the representations and warranties of Sellers set forth in Section 3.1 hereof, any other information or documents made available to Purchasers or their counsel, accountants or advisors with respect to the Business. 31 3.3 Survival of Representations and Warranties.

(b) For purposes of Section 3.3(a), a "third party" shall be deemed not to include Purchasers' affiliates. (c) Notwithstanding any investigation or audit conducted before or after the Closing Date or the decision of any party to complete the Closing, each party shall be entitled to rely upon the representations and warranties set forth herein; provided, however, that if on the Closing Date any of William L. Kacin, Gary J. Morgan, Robert Cane or Jeffrey H. Nicholas has actual knowledge that any representation or warranty made by Sellers is inaccurate as of the date made, Purchasers and their affiliates shall have no right or remedy after the Closing to the extent of such inaccuracy, and shall be deemed to have waived their rights to indemnification to the extent thereof. (d) Neither the identification of Jeffrey H. Nicholas in Section 3.3(c) nor his participation in the transactions contemplated hereby shall create any basis for disqualifying him or Fox, Rothschild, O'Brien & Frankel, LLP from representing Purchasers in any controversy or dispute arising out of the transactions contemplated hereby. 32 ARTICLE 4 INDEMNIFICATION 4.1 Indemnification by Sellers and Shareholders. 4.1.1 Indemnification by Sellers and Shareholders. Subject to the limitation set forth in Section 4.1.2 hereof, Sellers and Shareholders jointly and severally indemnify Purchasers, their affiliates, successors and assigns (each an "Indemnified Purchaser Party") against and agree to hold each of them harmless from any and all damage, loss, liability and expense (including, without limitation, reasonable expenses of investigation and reasonable attorneys' and accountants' fees and expenses) (collectively "Damages") in connection with any claim, demand, assessment, fine, penalty, judgment, deficiency, liability, cost, expense, action, suit, proceeding or judgment incurred or suffered by any Indemnified Purchaser Party arising out of any of: (a) any misrepresentation or breach of representation or warranty made by any Seller or Shareholder pursuant to this Agreement; (b) any breach of covenant or agreement made or to be performed by any Seller or Shareholder in this Agreement; and (c) any Excluded Liability as defined by Section 1.4.2 hereof. 4.1.2 Limitation on Sellers' and Shareholders' Liability for Breaches of Representations and Warranties. Sellers and Shareholders shall not be liable under Section 4.1.1(a) unless the aggregate amount of Damages with respect to all matters referred to in Section 4.1.1(a) exceeds $25,000 and then only to the extent of such excess and Sellers' and Shareholders' maximum liability under Section 4.1.1(a) shall not exceed $1,500,000; provided further, that Sellers and Shareholders shall not be liable under Section 4.1.1(a) for any Damages with respect to liabilities in excess of the amounts reserved therefor on the Effective Date Pro Forma Balance Sheet unless such liabilities exceed the aggregate of amount of all reserves on the Effective Date Pro Forma Balance Sheet, and then only to the extent of such excess. 4.1.3 Liability for Breach of Covenant and Excluded Liabilities. (a) The limitation on liability imposed by Section 4.1.2 hereof for Damages under Section 4.1.1(a) hereof shall not apply to Damages under Section 4.1.1(b) hereof or Section 4.1.1(c) hereof, each of which shall not be subject to such $25,000 threshold amount nor such $1,500,000 maximum amount, and shall be without limitation. 33 (b) The expiration provided for by Section 3.3 hereof of the representations and warranties set forth in Article 3 hereof does not apply to the indemnification obligations provided for by Section 4.1.1(b) hereof and Section 4.1.1(c) hereof. The expiration of a representation and warranty that may also be of similar subject matter to an Excluded Liability does not affect Purchasers' indemnity rights for the Excluded Liability. The parties further acknowledge that as pertains to a given subject matter, there may be differences in the scope of a representation and warranty, on the one hand, and an Excluded Liability, on the other hand, and that the accuracy of a representation and warranty shall not be deemed to limit a party's right to indemnity for an Excluded Liability, nor shall the absence of an indemnity claim for an Excluded Liability be deemed to limit a party's right to indemnification for breach of representation and warranty. 4.2 Indemnification by Purchasers. Purchasers jointly and severally indemnify Sellers and Shareholders, their affiliates, successors and assigns (each an "Indemnified Seller Party") against and agree to hold each of them harmless from any and all Damages in connection with any claim, demand, assessment, fine, penalty, judgment, deficiency, liability, cost, expense, action, suit, proceeding or judgment incurred or suffered by any Indemnified Seller Party arising out of: (a) any misrepresentation or breach of representation or warranty, covenant or agreement made or to be performed by any Purchaser pursuant to this Agreement; and (b) any Assumed Liability as defined by Section 1.4.1 hereof. 4.3 Method of Asserting Claims, etc. In the event that any claim or demand for which Sellers or Shareholders would be liable to an Indemnified Purchaser Party hereunder is asserted against or sought to be collected from an Indemnified Purchaser Party by a third party, the Indemnified Purchaser Party shall notify Sellers and Shareholders in writing of such claim or demand, specifying the nature of such claim or demand and the amount or the estimated amount thereof to the extent then feasible (which estimate shall not be conclusive of the final amount of such claim and demand) (the "Claim Notice"). The Claim Notice shall be given within fifteen (15) calendar days after an Indemnified Purchaser Party becomes aware of any fact, condition or event which may give rise to a claim for which indemnification may be sought hereunder. Notwithstanding the foregoing, the failure by an Indemnified Purchaser Party to give timely notice shall not affect its rights to indemnification hereunder, except to the extent to which Sellers or Shareholders shall demonstrate damage caused by such failure. Sellers and Shareholders shall have fifteen (15) calendar days from receipt of the Claim Notice (the "Notice Period") to notify the Indemnified Purchaser Party, (x) whether or not they dispute their liability to the Indemnified Purchasers Party hereunder with respect to 34 such claim or demand and (y) notwithstanding any such dispute, whether or not they desire, at their sole cost and expense, to defend the Indemnified Purchaser Party against such claim or demand. (a) If Sellers or Shareholders dispute their liability with respect to such claim or demand or the amount thereof (whether or not Sellers or Shareholders desire to defend the Indemnified Purchaser Party against such claim or demand as provided in paragraphs (b) and (c) below), such dispute shall be resolved in accordance with Section 4.5 hereof. Pending the resolution of any dispute by Sellers or Shareholders of their liability with respect to any claim or demand, such claim or demand shall not be settled by the Indemnified Purchaser Party without the prior written consent of Sellers or Shareholders. (b) In the event that Sellers or Shareholders notify the Indemnified Purchaser Party within the Notice Period that they desire to defend the Indemnified Purchaser Party against such claim or demand then, except as hereinafter provided, Sellers or Shareholders, respectively, shall have the right to defend the Indemnified Purchaser Party by appropriate proceedings, which proceedings shall be promptly settled or prosecuted by them to a final conclusion in such a manner as to avoid any risk of the Indemnified Purchaser Party becoming subject to liability for any other matter; provided, however, Sellers and Shareholders shall not, without the prior written consent of the Indemnified Purchaser Party, consent to the entry of any judgment against the Indemnified Purchaser Party or enter into any settlement or compromise which does not include, as an unconditional term thereof, the giving by the claimant or plaintiff to the Indemnified Purchaser Party of a release, in form and substance satisfactory to the Indemnified Purchaser Party, as the case may be, from all liability in respect of such claim or litigation. If any Indemnified Purchaser Party desires to participate in, but not control, any such defense or settlement, it may do so at its sole cost and expense. If, in the reasonable opinion of the Indemnified Purchaser Party, any such claim or demand or the litigation or resolution of any such claim or demand involves an issue or matter which could have a materially adverse effect on the business, operations, assets, properties or prospects of the Indemnified Purchaser Party, including without limitation the administration of the tax returns and responsibilities under the tax laws of any Indemnified Purchaser Party, then the Indemnified Purchaser Party shall have the right to control the defense or settlement of any such claim or demand and its reasonable costs and expenses shall be included as part of the indemnification obligation of Sellers and Shareholders hereunder; provided, however, that the Indemnified Purchaser Party shall not settle any such claim or demand without the prior written consent of Sellers or Shareholders, which consent shall not be unreasonably withheld. If the Indemnified Purchaser Party should elect to exercise such right, Sellers or Shareholders shall have the right to participate in, but 35 not control, the defense or settlement of such claim or demand at their sole cost and expense. (c) (i) If Sellers or Shareholders elect not to defend the Indemnified Purchaser Party against such claim or demand, whether by not giving the Indemnified Purchaser Party timely notice as provided above or otherwise, then the amount of any such claim or demand, or if the same be defended by Sellers or Shareholders or by the Indemnified Purchaser Party (but none of the Indemnified Purchaser Party shall have any obligation to defend any such claim or demand), then that portion thereof as to which such defense is unsuccessful, in each case shall be conclusively deemed to be a liability of Sellers and Shareholders hereunder, unless Sellers and Shareholders shall have disputed their liability to the Indemnified Purchaser Party hereunder, as provided in (a) above, in which event such dispute shall be resolved as provided in Section 4.5 hereof. (ii) In the event an Indemnified Purchaser Party should have a claim against Sellers or Shareholders hereunder that does not involve a claim or demand being asserted against or sought to be collected from it by a third party, the Indemnified Purchaser Party shall promptly send a Claim Notice with respect to such claim to Sellers and Shareholders. If Sellers or Shareholders dispute their liability with respect to such claim or demand, such dispute shall be resolved in accordance with Section 4.5 hereof; if Sellers or Shareholders do not notify the Indemnified Purchaser Party within the Notice Period that they dispute such claim, the amount of such claim shall be conclusively deemed a liability of Sellers or Shareholders, respectively, hereunder. (d) All claims for indemnification by an Indemnified Seller Party under this Agreement shall be asserted and resolved under the procedures set forth above substituting in the appropriate place "Indemnified Seller Party" for "Indemnified Purchaser Party" and variations thereof and "Purchasers" for "Sellers" and "Shareholders." (e) Each party shall cooperate, and cause their respective affiliates to cooperate, in the defense or prosecution of any claim or demand made by a third party and shall furnish or cause to be furnished such records, information and testimony, attend such conferences, discovery proceedings, hearings, trials or appeals, and make such filings with governmental authorities, as may be reasonably requested in connection therewith. Sellers shall reimburse an Indemnified Purchaser Party for its out-of-pocket expenses, including reasonable attorneys fees and expenses, incurred in connection with this provision in respect of any matter or claim for which such Indemnified Purchaser Party has a right of indemnity under this Agreement, and Purchasers shall indemnify an Indemnified Seller Party 36 for its out-of-pocket expenses, including reasonable attorneys fees and expenses, incurred in connection with this provision in respect of any matter or claim for which such Indemnified Seller Party has a right of indemnity under this Agreement. (f) Notwithstanding any of the foregoing provisions in Section 4.3 of this Agreement: (i) In the event that any claim or demand relating to Environmental Liabilities for which Sellers or Shareholders may be liable hereunder is asserted, Shareholders shall have the option to assume exclusive control of the resolution of any such claim or demand. Except as set forth below, Shareholders shall have satisfied their obligations under this Agreement with respect to any Environmental Liabilities as regards any affected real property if the result of any remediation meets or exceeds the least stringent standards, based on the use of such property at the Closing Date, required to comply with Environmental Laws as in effect on the Closing Date (or, at the Shareholders' option, as in effect on the date any remediation is concluded); provided, however, that Shareholders agree to use reasonable efforts to obtain any available approval from the applicable governmental authority of such remediation. Notwithstanding anything herein to the contrary, Shareholders' obligations under this Agreement shall not be considered satisfied to the extent to which such "least stringent standards" criteria shall result in the creation of any obligation, liability or duty on the part of an Indemnified Purchaser Party as regards such affected real property. (ii) Each Indemnified Purchaser Party agrees to take no action (such as, but not limited to, any drilling or testing of the soil or ground water) and that each will not affirmatively initiate any action by any Indemnified Purchaser Party or third party, including any governmental agency or authority, which could reasonably be expected to lead to a claim with respect to any such matter, except in each case to the extent believed by such Indemnified Purchaser Parties, in good faith, to be required by any Environmental Law. (iii) Each Indemnified Purchaser Party agrees to maintain, to instruct its executive officers and directors to maintain, and to require each New Hire (as hereafter defined) to execute a confidentiality agreement substantially similar to the Confidentiality Agreement (as hereafter defined) executed by Sellers' existing employees. For purposes of this provision, a "New Hire" is any new employee of Met-Pro's Flex-Kleen division, 37 other than a New Employee as defined in Article 5 hereof. The parties acknowledge that Sellers' existing employees have executed confidentiality agreements (each a "Confidentiality Agreement") with Sellers, which at Closing shall be assigned to Purchasers. (iv) Notwithstanding any breach by any New Hire or New Employee of his confidentiality obligation, the indemnification rights of an Indemnified Purchaser Party as pertains to environmental matters shall not be deemed waived or limited unless Sellers or Shareholders shall demonstrate that the Indemnified Purchaser Party conspired or acted in concert with such breaching New Hire or New Employee in regards to such breach. In addition, notwithstanding any breach by an Indemnified Purchaser Party of its obligations under Section 4.3(f)(iii), an Indemnified Purchaser Party's indemnification rights hereunder shall not be deemed waived or limited except to the extent to which Sellers or Shareholders shall establish that such breach was the proximate cause of the governmental or other third party action. Under no event shall an Indemnified Purchaser Party's indemnification rights be deemed waived or limited for any action taken by Helser Industries, its successors and assigns, except to the extent to which an Indemnified Purchaser Party shall act with regard to Helser Industries, its successors and assigns in breach of Section 4.3(f)(ii) hereof. (v) No obligation of an Indemnified Purchaser Party under Section 4.3 (f)(iii) shall be deemed breached by (A) the filing by Met-Pro of a copy of this Agreement, exclusive of the Disclosure Schedules and Exhibits, with any governmental agency pursuant to a good faith belief that such filing is required by law or (B) any disclosure made to any governmental agency or other third party to the extent believed by the disclosing Indemnified Purchaser Party, in good faith, to be required by any Environmental Law. (vi) Sellers or Shareholders agree to use reasonable efforts to ensure that any actions taken by Sellers or Shareholders or their representatives in connection herewith on property then occupied by Purchasers or their successors are performed in a manner which is not disruptive to the normal operation of such property. Sellers or Shareholders shall promptly furnish Purchasers and its successors with a copy of any written engineering, environmental or other similar report pertaining to the property. 4.4 Payment. Upon the determination of the liability under Section 4.3 or 4.5 hereof, the appropriate party shall pay to the other, as the case may be, within ten (10) calendar days after such determination, the amount of any claim for indemnification made hereunder. The first $500,000 (five 38 hundred thousand dollars) of Sellers' payment obligations for claims under Section 4.1.1(a) hereof shall initially be satisfied with withdrawals from the Escrow Closing Payment held under the Escrow Agreement. Sellers shall directly pay Purchasers for claims under Section 4.1.1(b) and Section 4.1.1 (c) hereof. In the event that the indemnified party is not paid in full for any such claim promptly after the other party's obligation to indemnify has been determined in accordance herewith, it shall have the right, notwithstanding any other rights that it may have against any other person, firm or corporation, to set off the unpaid amount of any such claim against any amounts owed by it under any agreements entered into pursuant to this Agreement. Upon the payment in full of any claim, either by set off or otherwise, the entity making payment shall be subrogated to the rights of the indemnified party against any person, firm or corporation with respect to the subject matter of such claim. 4.5 Arbitration. (a) All disputes under this Article 4 shall be settled by arbitration in Philadelphia, Pennsylvania, before a single arbitrator (the "Arbitrator") pursuant to the rules of the American Arbitration Association. Arbitration may be commenced at any time by any party hereto giving written notice to each other party to a dispute that such dispute has been referred to arbitration under this Section 4.5. The Arbitrator shall be selected by the joint agreement of Sellers and Purchasers, but if they do not so agree within twenty (20) days after the date of the notice referred to above, the selection shall be made pursuant to the rules from the panels of arbitrators maintained by such Association. Any award rendered by the Arbitrator shall be conclusive and binding upon the parties hereto; provided, however, that any such award shall be accompanied by a written opinion of the Arbitrator giving the reasons for the award. This provision for arbitration shall be specifically enforceable by the parties and the decision of the Arbitrator in accordance herewith shall be final and binding and there shall be no right of appeal therefrom. Each party shall pay its own expenses of arbitration and the expenses of the Arbitrator shall be equally shared; provided, however, that if in the opinion of the Arbitrator any claim for indemnification or any defense or objection thereto was unreasonable, the Arbitrator may assess, as part of his award, all or any part of the arbitration expenses of the other party (including reasonable attorneys' fees) and of the Arbitrator against the party raising such unreasonable claim, defense or objection. (b) To the extent that arbitration may not be legally permitted hereunder and the parties to any dispute hereunder may not at the time of such dispute mutually agree to submit such dispute to arbitration, any party may commence a civil action in a court of appropriate jurisdiction to resolve disputes hereunder. Nothing contained in this 39 Section 4.5 shall prevent the parties from settling any dispute by mutual agreement at any time. (c) Sellers or Shareholders may apply to the Arbitrator for a written determination that Purchasers filed a Notice of Claim (as defined in Section 4 of the Escrow Agreement) in bad faith and principally for the purpose of delaying the release to Sellers or Shareholders of any portion of the Escrow Fund (as defined in Section 1 of the Escrow Agreement). Upon such a determination, the Arbitrator may assess against Purchasers all or any part of the arbitration expenses of Sellers or Shareholders (including reasonable attorneys' fees) and of the Arbitrator. 4.6 Compliance with Bulk Sales Laws. The parties hereby waive compliance by Purchasers and Sellers with the bulk sales law and any other similar laws in any applicable jurisdiction in respect of the transactions contemplated by this Agreement. Purchasers, jointly and severally, indemnify Sellers and Shareholders from, and hold them harmless against, any liabilities, damages, costs and expenses resulting from or arising out of (i) the parties' failure to comply with any of such laws in respect of the transactions contemplated by this Agreement, or (ii) any action brought or levy made as a result thereof, other than those liabilities which have been expressly assumed, on such terms as expressly assumed, by Purchasers pursuant to this Agreement. It is agreed that the Purchasers shall not require Flex-Kleen Canada to comply, or to assist the Purchasers to comply, with the requirements of section 6 of the Retail Sales Tax Act (Ontario), or such other comparable legislation in other provinces as may be applicable to the transfer of the Assets used by Flex-Kleen Canada in the Business under this Agreement. Notwithstanding the foregoing, Sellers agree to indemnify and hold harmless the Purchasers from and against any claims which may be made or brought against the Purchasers or which the Purchasers may suffer or incur as a result of, in respect of, or arising out of such non-compliance. 4.7 Calculation of Damages. (a) The Sellers and Shareholders shall not be liable under Section 4.1 hereof for (i) any Damages to the extent that the Indemnified Purchaser Party has been compensated for such claim or matter pursuant to Section 6.11 hereof or pursuant to any other insurance proceeds realized by the Indemnified Purchaser Party or its affiliates for such claim or matter, (ii) consequential Damages, (iii) Damages for lost profits incurred by the Indemnified Purchaser Party, or (iv) punitive Damages. 40 (b) Notwithstanding Section 4.7(a)(iii), Sellers and Shareholders shall be liable for Damages for lost profits for any claim or matter arising under Section 6.6(a) hereof. (c) Warranty costs and claims arising after the Closing Date for product sold by Sellers prior to the Effective Date shall be calculated for purposes of determining Damages in a manner consistent with Sellers' past practices during the twelve months ended July 31, 1998. 4.8 Exclusive Remedy. The indemnification rights of the parties under this Article 4 shall be the sole and exclusive rights and remedies of the parties hereto for misrepresentations and breaches of representations and warranties set forth in Article 3 hereof. The foregoing shall not be deemed, however, to limit the parties' rights and remedies as may exist in law, equity or otherwise for breach of any agreement or covenant hereunder. 4.9 Goods and Services Gross-up On Indemnification. Where an amount is payable by an Indemnified Purchaser Party or Indemnified Seller Party as indemnification pursuant to the terms of this Agreement and the Excise Tax Act (Canada) provides that GST is deemed to have been collected by the payee thereof, the amount so payable as determined without reference to this Section 4.9 (the "Indemnification Amount") shall be increased by an amount equal to the rate of GST applied to the Indemnification Amount in accordance with the Excise Tax Act (Canada). ARTICLE 5 EMPLOYEE BENEFIT MATTERS 5.1 Employees and Offers of Employment. (a) Purchasers shall make offers of employment as of the Closing Date to all of the employees who work for the Business immediately prior to the Closing Date for positions similar to those performed immediately prior to the Closing Date (i) at their current salaries and (ii) on such other terms and conditions which, for a period of no less than one year following the Closing Date, will be no less favorable in the aggregate to those generally provided to similarly situated employees of Purchasers. All employees who accept such offers of employment shall be referred to herein as "New Employees." Subject to the provisions hereof, all New Employees will become employees of Purchasers on the Closing Date, except that any employee of the 41 Business who is inactive (including without limitation employees who are disabled) as of the Closing Date will become a New Employee after such employee returns to work on the earlier of (i) the date such employee becomes eligible to participate in life, short-term disability and health plans of Purchasers or their affiliates and (ii) the tenth business day following such employee returns to work. Purchasers shall promptly reimburse Sellers for the costs associated with such employee including salary and cost of benefits between the date such employee returns to work and the date such employee becomes a New Employee. The date an employee becomes an employee of Purchasers is a "Hire Date." Nothing in this Article 5 or elsewhere in this Agreement is intended to confer upon any employee of Sellers any right to continued employment by Purchasers and it is understood that Purchasers shall employ any such person on an "at will" basis. (b) Notwithstanding anything in Section 5.1 (a) herein to the contrary, Met-Pro Canada at Closing shall offer employment on terms and conditions which shall not trigger any severance obligations under Canadian, statutory or common law or otherwise (excepting, however, any obligation under the AWT Air Severance Pay Plan) to Maurice and Joan Hamilton, and Purchasers shall be jointly and severally liable to pay any severance payment under Canadian statutory or common law or otherwise (excepting, however, any payment due under the AWT Air Severance Pay Plan) to Maurice and Joan Hamilton for years of service accrued as an employee of Flex-Kleen Canada as of the date of the Closing. Purchasers shall solely assume the defense of any claim for severance brought by such persons following Closing, whether under statutory or common law or otherwise (excepting, however, the AWT Air Severance Pay Plan), and shall be solely liable for the costs and expenses including legal fees in connection with any such claim. Prior to Closing, except for the transactions contemplated by this Agreement, Sellers shall take no act which would trigger any severance obligation under Canadian, statutory or common law or otherwise to Maurice and Joan Hamilton. (c) Prior to Closing, Sellers agree to give written notice to its employees not eligible as of Closing for post-retirement benefits of the termination and unavailability of post-retirement benefits, and of the elimination of any benefits under the AWT Air Severance Pay Plan, and to provide evidence of same at Closing to Purchasers. 5.2 Non-Solicitation. (a) Until the third anniversary of the Closing Date, Sellers and Shareholders will not, directly or indirectly, solicit or offer employment to any person who, after the Closing Date, is then an employee of Purchasers, or who has terminated employment with 42 Purchasers without the consent of Purchasers within 180 days of such solicitation or offer. (b) Until the third anniversary of the Closing Date, Purchasers will not, and will cause their affiliates not to, directly or indirectly, solicit or offer employment to any person who, after the Closing Date, is then an employee of Sellers or an affiliate of Sellers or who has terminated employment with Sellers or any affiliate of Sellers without the consent of Sellers or such affiliate of Sellers within 180 days of such solicitation or offer. 5.3 Vacation Credit. From and after the Closing Date, New Employees shall be entitled to use their unused vacation benefits earned as employees of Sellers after January 1, 1998 under Sellers' vacation arrangements that were in effect as of January 1, 1998. All vacation benefits of Sellers' employees earned as of December 31, 1997, including but not limited to any equitable adjustments made or granted during 1998 for prior service to Sellers, not used or paid in the ordinary course of business prior to the Effective Date shall be paid by Sellers to such employees within sixty (60) days of the Closing Date in accordance with Exhibit 5.3. 5.4 COBRA. Subsequent to the Closing Date, Purchasers shall be liable for continuation of health care coverage required by Code Section 4980B and ERISA Section 601 through 608 ("COBRA") with respect to New Employees, and Sellers shall be liable for health care continuation required by COBRA for any of their employees who are not New Employees. Purchasers shall ensure that any COBRA requirements are met with respect to any "qualifying event" with respect to a New Employee (and covered family members of a New Employee) occurring on or after the Closing Date. Sellers shall ensure that any COBRA requirements are met with respect to any "qualifying event" with respect to Sellers' employees (and covered family members of such employees) who do not become New Employees occurring on or after the Closing Date. Prior to or on the Closing, Sellers shall give appropriate written notices to their respective employees of the Business as to the occurrence of the transactions contemplated by this Agreement. 5.5 Health Care and Prescription Benefits; Other Employee Benefits. (a) All health care and prescription claims incurred by Sellers' employees between the Effective Date and the Closing Date and between the Closing Date and October 31, 1998 shall be paid pursuant to Sellers' insurance policies or Sellers' self-insurance plans subject to no deductible. At Closing, Purchasers shall reimburse Sellers for the portion of the health care and prescription plan "deemed premium" for Sellers' employees for the period between the Effective Date and September 30, 1998, in an amount consistent with and based upon the per month premium charges to Flex-Kleen during the period between November 1, 1997 and the Effective Date, pursuant to Schedule 5.5(a) (the "Closing Health Care and Prescription Plan Premium Reimbursement Payment").
