In the event that any limitation under this Section 8.5 is found to be unreasonable or otherwise invalid in any jurisdiction, in whole or in part, Lewis acknowledges and agrees that such limitation shall remain and be valid in all other jurisdictions. 8.5.5 The Shareholders have had access to, and have gained knowledge with respect to the Business and the SP Companies, and the related trade secrets, financial results and information, processes and techniques, plans, research, designs, concepts, methods of doing business and information concerning customers and suppliers, and other valuable and confidential information, which is not generally known to the public (the "Confidential Information"). The 38 - STOCK PURCHASE AGREEMENT parties acknowledge that unauthorized disclosure or misuse of the Confidential Information following the date of this Agreement may cause irreparable damage to Buyer and the SP Companies. The parties also agree that covenants by the Shareholders not to make unauthorized disclosures of the Confidential Information are essential to the growth and stability of the SP Companies. Accordingly, each Shareholder agrees that such Shareholder shall not use or disclose directly or indirectly or cause or permit to be used or disclosed any Confidential Information to any Person other than Buyer or the SP Companies. 8.5.6 Nothing in Section 8.5.5 shall prevent the Shareholders from using or disclosing any such Confidential Information as counsel to the Shareholders advises must be used or disclosed in connection with ongoing litigation or pursuant to applicable law or in the course of a defense of a claim assumed by Lewis as an Indemnity Obligor pursuant to Section 9.4, notice of which disclosure shall be promptly delivered to Buyer. 8.5.7 Each Shareholder acknowledges that Buyer and the SP Companies may suffer damages incapable of ascertainment in the event the provisions of this Section 8.5 are breached and that they may be irreparably damaged in the event that the provisions of this Section 8.5 are not enforced. Therefore, should any dispute arise with respect to the breach or threatened breach of any provision of this Section 8.5, each Shareholder agrees and consents that, in addition to any and all other remedies available to Buyer, an injunction or restraining order or other equitable relief may be issued or ordered by a court of competent jurisdiction restraining any breach or threatened breach of any provision of this Section 8.5. ARTICLE 9 SURVIVAL AND INDEMNIFICATION 9.1 SURVIVAL OF REPRESENTATIONS, WARRANTIES, COVENANTS AND AGREEMENTS 9.1.1 All representations and warranties by the Shareholders and the SP Companies contained in this Agreement shall survive the Closing Date for the duration of the Claims Period. 9.1.2 All covenants and agreements by the Shareholders and the SP Companies contained in this Agreement including, without limitation, the indemnification obligations contained in this Article, shall survive the Closing Date until fully performed or discharged. 9.1.3 All representations and warranties by Buyer contained in this Agreement shall survive the Closing Date for the duration of the Claims Period. 9.1.4 All covenants and agreements by Buyer contained in this Agreement including, without limitation, the indemnification obligations contained in this Article, shall survive the Closing Date until fully performed or discharged. 39 - STOCK PURCHASE AGREEMENT 9.1.5 Except for any remedy of specific performance or any other equitable remedy (excluding an equitable remedy involving the payment of money damages) to which any party may be entitled, and except in the case of fraud or any action required to enforce the indemnification provisions of this Agreement, the indemnification provisions set forth in this Article 9 shall provide the sole and exclusive rights and remedies under which a party to this Agreement may assert a claim against another party with respect to (i) any and all breaches of any representation or warranty contained herein made to the party asserting the claim, (ii) any and all breaches of covenants contained herein made to such party under this Agreement, or (iii) any other claim, action, demand, loss, cost, expense, liability, including environmental liabilities, penalty or other damage relating to or arising out of this Agreement. 9.2 INDEMNIFICATION BY THE SHAREHOLDERS 9.2.1 The Shareholders, jointly and severally, hereby agree, except in the case of any breach of, or inaccuracy in, any representation or warranty by a Shareholder as set forth in Article 4, in which case each Shareholder hereby severally agrees, to defend, indemnify and hold harmless Buyer and the SP Companies from, against and in respect to any Loss suffered or incurred by Buyer or the SP Companies by reason of (i) a breach of, or inaccuracy in, any representation or warranty by the Shareholders or the SP Companies contained in this Agreement, (ii) the nonfulfillment of any covenant or agreement by the Shareholders or the SP Companies contained in this Agreement, (iii) all Proceedings incident to any of the foregoing.

The amount for which the Shareholders shall be liable for Environmental Liabilities shall not be subject to the Shareholders Minimum Amount and shall not exceed $2,500,000. The Shareholders shall be liable on a dollar for dollar basis for the first $1,750,000 of Environmental Liabilities and shall be liable for one half of each dollar of Environmental Liabilities in excess of $1,750,000 up to a maximum aggregate liability of $2.5 million. Any claim for indemnification with respect to Preexisting Liabilities must be initiated during the Claims Period. The Claims Period shall not apply to any claim for indemnification with respect to Litigation Liabilities and such a claim may be initiated at any time. Any claim for indemnification with respect to Environmental Liabilities must be initiated on or before the third anniversary of the Closing Date. Promptly after the third anniversary of the Closing Date, Buyer and the Shareholders shall meet and endeavor to agree on the amount required to resolve any outstanding claims for indemnification for Environmental Liabilities ("Environmental Accrual"), and the balance of the Environmental Liabilities Fund (as defined in the Escrow Agreement) in excess of any such agreed Environmental Accrual, if any, shall be paid to the Shareholders by the Escrow Agent. If Buyer and the Shareholders cannot so agree, the parties shall submit their dispute to arbitration pursuant hereto, and following a determination by arbitration of the Environmental Accrual, the balance of the Environmental Liabilities Fund in excess of any such arbitrated Environmental Accrual, if any, shall be paid to the Shareholders. 40 - STOCK PURCHASE AGREEMENT 9.2.3 The Shareholders shall be liable under this Section 9.2 to the extent that the aggregate amount of the Losses incurred by reason of the matters described in this Section 9.2 exceeds $300,000 (the "Shareholders Minimum Amount"), and the aggregate amount payable by the Shareholders as indemnification pursuant to this Section 9.2 shall be limited to 50% of the Purchase Price as adjusted by the Purchase Price Adjustment. Notwithstanding the foregoing, the limitations set forth in the preceding sentence shall not apply to any claim for indemnification with respect to Litigation Liabilities or to any claim for indemnification with respect to any Loss suffered or incurred by Buyer or the SP Companies (i) by reason of any breach of, or inaccuracy in, the representations and warranties contained in Section 4.2 or (iii) by reason of fraud. The amount payable by the Shareholders under this Section 9.2 shall be net of any insurance proceeds recovered by Buyer or the SP Companies in connection with the facts giving rise to Buyer's right to indemnification. 9.3 INDEMNIFICATION BY BUYER Buyer hereby agrees to defend, indemnify and hold harmless the Shareholders from, against and in respect of any Loss suffered or incurred by the Shareholders by reason of (i) a breach of, or inaccuracy in, any representation or warranty by Buyer contained in this Agreement, or (ii) the nonfulfillment of any covenant or agreement by Buyer contained in this Agreement, and (iii) all Proceedings incident to any of the foregoing. Buyer shall be liable under clauses (i), (ii) and (iii) of the preceding sentence to the extent that the aggregate amount of the Losses incurred by reason of the matters described in such clauses exceeds $300,000 ("Buyer's Minimum Amount"). 9.4 NOTIFICATION AND DEFENSE OF CLAIMS OR ACTIONS 9.4.1 As used in this Section, any party seeking indemnification pursuant to this Section is referred to as an "Indemnified Party" and any party from whom indemnification is sought pursuant to this Section is referred to as an "Indemnity Obligor." An Indemnified Person which proposes to assert the right to be indemnified under this Article shall, pursuant to the notice provisions of this Agreement, submit a written demand for indemnification setting forth in summary form the facts as then known which form the basis for the claim for indemnification. 9.4.2 With respect to claims based on actions by third parties, an Indemnified Party shall, within twenty (20) days after the receipt of notice of the commencement of any Proceeding against it in respect of which a claim for indemnification is to be made against an Indemnity Obligor, notify the Indemnity Obligor in writing of the commencement of such Proceeding, enclosing a copy of all papers served; provided, however, that the failure to so notify the Indemnity Obligor of any such Proceeding shall not relieve the Indemnity Obligor from any liability which it may have to the Indemnified Party, except to the extent that the Indemnity Obligor is prejudiced thereby. Thereafter, the Indemnified Party shall deliver to the Indemnity Obligor, within twenty (20) days after receipt by the Indemnified Party, copies of all further notices relating to such claim. 41 - STOCK PURCHASE AGREEMENT 9.4.3 If a third-party claim is made for which an Indemnified Party is entitled to indemnification pursuant to this Article, the Indemnity Obligor will be entitled to participate in the defense of such claim and, if it so chooses, and provided that it acknowledges its obligation to indemnify the Indemnified Party, to assume primary responsibility for the defense of such claim with counsel selected by the Indemnity Obligor and not reasonably objected to by the Indemnified Party. Should the Indemnity Obligor assume the defense of such claim, the Indemnity Obligor will not be liable to the Indemnified Party for any legal expenses subsequently incurred by the Indemnified Party in connection with the defense of such claim. 9.4.4 If the Indemnity Obligor assumes the defense of a third-party claim as set forth in Section 9.4.3, then (i) in no event will an Indemnified Party admit any liability with respect to, or settle, compromise or discharge, any such claim without the Indemnity Obligor's prior written consent and (ii) each Indemnified Party shall be entitled to participate in, but not control, the defense of such claim with its own counsel at its own expense. If the Indemnity Obligor does not assume the defense of any such claim, an Indemnified Party may defend such claim in a manner as it may deem appropriate (including, but not limited to, settling such claim, after giving twenty (20) days prior written notice of such settlement to the Indemnity Obligor, on such terms as the Indemnified Party may deem appropriate). 9.4.5 In the event that any claim for indemnification is made with respect to any third-party claim pursuant to this Article, (i) the party assuming primary responsibility for the defense of such claim shall at all times keep the other party informed as to the status of such claim and (ii) the party not primarily responsible for the defense of such claim shall cooperate fully with the other party in connection with such defense. 9.5 USE OF ESCROW FUNDS FOR INDEMNIFICATION In the event that Buyer is entitled to indemnification from the Shareholders pursuant to Section 9.2, Buyer shall first seek payment from available Escrow Funds in accordance with the terms and conditions of the Escrow Agreement. 9.6 RELIANCE No disclosure by any party ("Disclosing Party") to this Agreement nor any investigation made by or on behalf of another party with respect to the Disclosing Party shall be deemed to affect the other party's reliance on the respective representations and warranties contained in this Agreement and shall not effect a waiver of that party's rights to indemnity as herein provided for the breach of any of said representations and warranties. 9.7 PURCHASE PRICE ADJUSTMENTS Notwithstanding anything in this Agreement to the contrary, the Shareholders shall not have any liability pursuant to this Article 9 for any Loss if and to the extent that Buyer has already been compensated for the same Loss through a reduction in the Purchase Price pursuant to the operation of Section 2.4. 42 - STOCK PURCHASE AGREEMENT ARTICLE 10 GENERAL PROVISIONS 10.1 EXPENSES The Shareholders shall bear all expenses incurred by the Shareholders and the SP Companies in connection with the Transaction, including the fees and expenses of any attorneys, accountants, investment bankers, brokers, finders or other intermediaries or other Persons engaged by the Shareholders or the SP Companies.
