During such period, Purchaser shall make available its accounting staff and other relevant personnel to respond to questions of Seller relating to the Closing Balance Sheet, the Capital Expenditures Statement, and the Working Capital Statement at commercially reasonable times and upon commercially reasonable advance notice and shall furnish to Seller such work papers and other documents and information relating to the Closing Balance Sheet, the Capital Expenditures Statement, and the Working Capital Statement as Seller may commercially reasonably request and are commercially reasonably available to Purchaser or its Affiliates. An Objection shall set forth a general description of the basis of the Objection and the adjustments to the Closing Balance Sheet, the Capital Expenditures Statement, and/or the Working Capital Statement that Seller believes should be made, which Objection must be delivered to Purchaser on or before the last day of such 45-day period, in which case each item in the Closing Balance Sheet, the Capital Expenditures Statement, and the Working Capital Statement that is not disputed in such Objection shall be deemed to be agreed to by Seller and shall be final and binding upon the Parties.

The selected accounting firm shall be directed by the Parties to (i) determine each disputed item on the Closing Balance Sheet on the basis consistent with the May Balance Sheet, (ii) determine each disputed item on the Capital Expenditures Statement in accordance with GAAP applied on a consistent basis and in accordance with this Agreement, (iii) determine each disputed item on the Working Capital Statement in accordance with GAAP applied on a consistent basis and in accordance with this Agreement, (iv) render its determination within 30 days after such referral for binding resolution is made, and (v) upon reaching a determination, deliver to both Purchaser and Seller a modified Closing Balance Sheet, Capital Expenditures Statement, and/or Working Capital Statement reflecting the items that have become final and binding upon the Parties and the accounting firm’s determination of each disputed item. The determination by the accounting firm so selected of the Closing Balance Sheet, the Capital Expenditures Statement, and/or the Working Capital Statement (with such

modifications therein, if any, as reflect such determination) shall be conclusive and binding upon the Parties. The fees and expenses of such accounting firm shall be shared equally by the Seller Parties, on the one hand, and Purchaser, on the other hand. Nothing herein shall be construed to authorize or permit the accounting firm to determine any questions or matters whatsoever under or in connection with this Agreement except for the resolution of the disputed items submitted to them for determination in accordance with this Section 3.1(g).

(h) Each Party shall provide the other Parties and their respective representatives reasonable access to the premises of the Business, to their respective books and records and to their respective appropriate personnel for purposes of preparing and confirming the Closing Balance Sheet, the Capital Expenditures Statement, the Working Capital Statement, and the CAPEX Statement.

(i) (A) Subject to sub-clause (C) of Section 3.1(i), Seller shall earn, and Purchaser shall pay to Seller, as additional consideration for the Purchased Assets (the “Earn Out”), an amount equal to the product of (i) the amount, if any, by which the Business’s Earn Out EBITDAP, as defined in Schedule 3.1(i), for the 12-month period from October 1, 2005 through and including September 30, 2006 (the “Earn Out Period”) exceeds Eighteen Million Seven Hundred Fifty Thousand Dollars ($18,750,000) and (ii) four (4); provided, that the Parties agree that the amount, if any, payable under this Section 3.1(i)(A) shall not exceed in the aggregate Five Million Dollars ($5,000,000). During the Earn Out Period and until such time as the Earnout amount is paid to Seller, Purchaser shall cause the books and records of the Business to be adequately maintained in a commercially reasonable manner so that any amounts due pursuant to this Section 3.1(i) can be determined. If (i) the amount of the Earn Out that becomes due under this Section 3.1(i)(A) equals Five Million Dollars ($5,000,000), and (ii) any EBITDAP Adjustment previously has been paid by Seller to Purchaser, then Purchaser shall repay Seller, in addition to the Earn Out, and at the same time of such payment, the amount of such previously paid EBITDAP Adjustment.

(B) In the event that the Business does not achieve the EBITDAP for the period October 1, 2005 through December 31, 2005, as set forth on Schedule 3.1(i) (“Quarterly EBITDAP Target”), then Seller shall pay to Purchaser a sum equal to the product of (i) the amount by which the Quarterly EBITDAP Target exceeds the actual EBITDAP for that same period, and (ii) four (4) (“EBITDAP Adjustment”), provided that the EBITDAP Adjustment shall not exceed One Million Dollars ($1,000,000). During December 2005, the Chief Financial Officer of Purchaser shall consult with the Chief Financial Officer of Seller concerning the conduct of the Business, to assure that the affairs of the Business are conducted in a commercially reasonable manner so that any amounts due pursuant to this Section 3.1(i)(B) can be determined appropriately. As soon as Purchaser has closed the books of the Business for December 2005, Purchaser shall calculate the EBITDAP Adjustment and deliver to Seller a statement (the “EBITDAP Adjustment Statement”) which shall set forth the EBITDAP Adjustment calculation, together with commercially reasonable supporting documentation. Following receipt of the EBITDAP Adjustment Statement, Seller shall have 30 calendar days to review the EBITDAP Adjustment Statement after which period, if Seller has not disputed in writing

(an “EBITDAP Adjustment Objection”) the EBITDAP Adjustment Statement, Seller shall be deemed to have accepted and agreed with the EBITDAP Adjustment Statement, and such statement shall be final and binding upon the Parties. During such period, Purchaser shall make available at commercially reasonable times and upon commercially reasonable advance notice its accounting staff and other relevant personnel to respond to questions of Seller and its representatives relating to the EBITDAP Adjustment Statement and shall furnish to Seller such work papers and other documents and information relating to the EBITDAP Adjustment as Seller may commercially reasonably request and are commercially reasonably available to Purchaser or its Affiliates. An EBITDAP Adjustment Objection shall set forth a general description of the basis of the EBITDAP Adjustment Objection and the adjustments to the EBITDAP Adjustment that Seller believes should be made, which EBITDAP Adjustment Objection must be delivered to Purchaser on or before the last day of such 30-day period. Purchaser shall have 10 calendar days from receipt to review and respond to the EBITDAP Adjustment Objection. In the event there remains no dispute regarding the amount of the EBITDAP Adjustment, Seller shall pay to Purchaser the amount of the EBITDAP Adjustment forthwith. Payment of the EBITDAP Adjustment shall be made to Purchaser by wire transfer in immediately available funds.

(C) Payment of any amount due to Seller pursuant to sub-clause (A) of this Section 3.1(i) on or in respect of the Earn Out or repayment of the EBITDAP Adjustment shall be subject to the restrictions on such payment contained in the Credit Agreements (as defined in the Note). Accordingly, Purchaser shall make payment of the Earn Out and repayment of the EBITDAP Adjustment, if any, on the first Business Day on which payment thereof is permitted by the Credit Agreements. If Purchaser is prevented by the Credit Agreements from making payment of all or any part of the Earn Out and repayment of the EBITDAP Adjustment, if any, on the date when due hereunder (the “Earn Out Original Due Date”) or if the Credit Agreements allow such repayment and Purchaser fails to pay Seller such amount, then the unpaid amount will accrue interest from the Earn Out Original Due Date until paid at a rate per annum equal to the Interest Rate. Any such interest will be paid on the first Business Day it is permitted to be paid under the Credit Agreements. Any accrued interest paid shall be paid in full on the date on which payment on the Earn Out is permitted to be paid under the Credit Agreements. Any accrued interest which for any reason has not theretofore been paid shall be paid in full on the date on which the final payment on the Earn Out is made. Interest shall be calculated on the basis of actual number of days elapsed and a 360-day year. Three–month U.S. dollar LIBOR shall be determined by the Purchaser on the Earn Out Original Due Date and thereafter on each successive Interest Reference Date and shall be the quotation of “London Interbank Offered Rates (Libor)” on any such date appearing in the “Money Rates” section of the western edition of The Wall Street Journal. If The Wall Street Journal is not published on any Interest Reference Date, such determination shall be made on the first publication date thereafter. If not available therein on any such determination date, an equivalent quotation shall be obtained from such other publication as the Purchaser reasonably shall select. Three–month U.S. dollar LIBOR as so determined on any such determination date shall remain in effect for purposes of interest accrual hereunder until the next determination date. In lieu of payment in cash of any interest due hereunder prior to the permitted payment of the Earn Out, any and all such interest on the outstanding amount of the Earn Out shall be added to, and become a part of, the Earn Out amount on each Interest Reference Date and at final payment.

(j) Within three (3) days after Purchaser files its Form 10-K for the year ended September 30, 2006, Purchaser shall calculate the Earn Out and deliver to Seller a statement (the “Earn Out Statement”) which shall set forth the Earn Out calculation, together with commercially reasonable supporting documentation. Following receipt of the Earn Out Statement, Seller shall have 45 calendar days to review the Earn Out Statement after which period, if Seller has not disputed in writing (an “Earn Out EBITDAP Objection”) the Earn Out Statement, Seller shall be deemed to have accepted and agreed with the Earn Out Statement, and such statement shall be final and binding upon the Parties. During such period, Purchaser shall make available at commercially reasonable times and upon commercially reasonable advance notice its accounting staff and other relevant personnel to respond to questions of Seller and its representatives relating to the Earn Out Statement and shall furnish to Seller such work papers and other documents and information relating to the Earn Out Statement as Seller may commercially reasonably request and are commercially reasonably available to Purchaser or its Affiliates. An Earn Out EBITDAP Objection shall set forth a general description of the basis of the Earn Out EBITDAP Objection and the adjustments to the Earn Out Statement that Seller believes should be made, which Earn Out EBITDAP Objection must be delivered to Purchaser on or before the last day of such 45-day period. If the Earn Out Statement is not disputed in an Earn Out EBITDAP Objection, it shall be deemed to be agreed to by Seller and shall be final and binding upon the Parties. Purchaser shall have 30 calendar days from receipt to review and respond to the Earn Out EBITDAP Objection.

(k) The Parties shall attempt in good faith to reach an agreement with respect to any matters in dispute regarding the Earn Out Statement. If the Parties are unable to reach agreement with respect to the Earn Out Statement within 30 calendar days following the delivery of Purchaser’s response to an Earn Out EBITDAP Objection, the Earn Out Statement shall be referred for final binding resolution to an accounting firm mutually acceptable to both Parties or, in the absence of such agreement, by an accounting firm (with no existing or prior material business with either Seller or Purchaser) of national reputation selected by lot. The selected accounting firm shall be directed by the Parties to (i) determine that the Earn Out Statement is consistent with the provisions of Section 3.1(i), (ii) render its determination within 30 days after such referral for binding resolution is made, and (iii) upon reaching a determination, deliver to both Purchaser and Seller a modified Earn Out Statement reflecting the accounting firm’s determination. The determination by the accounting firm so selected of the Earn Out Statement (with such modifications therein, if any, as reflect such determination) shall be conclusive and binding upon the Parties. The fees and expenses of such accounting firm shall be shared equally by the Seller Parties, on the one hand, and Purchaser, on the other hand. Nothing herein shall be construed to authorize or permit the accounting firm to determine any questions or matters whatsoever under or in connection with this Agreement except for the resolution of the Earn Out Statement submitted to it for determination in accordance with this Section 3.1(l). Payment of the Earn Out shall be made to Seller by wire transfer in immediately available funds.

Schedule 9.3(m) — Exceptions to Permits

Purchaser acknowledges that as noted on Schedule 4.3, the State of California Environmental Protection Agency (Cal-EPA) Department of Toxic Substances Control (DTSC) sent letters to Seller dated December 9, 2004 and September 2. 2005 setting forth the DTSC’s determination that waste stream deactivation as practiced by the Business constitutes treatment of a hazardous waste for which a Hazardous Waste Facility permit is required.

Due to DTSC’s actions, a question remains as to whether such a permit is required. As a result, the Parties have agreed that the execution of a Consent Agreement, pursuant to Section 9.3(o) of the Purchase Agreement, shall be deemed to satisfy the Closing condition set forth in Section 9.3(m) of the Purchase Agreement.
