51 (b) Notwithstanding the foregoing, the limitations set forth in this Section 6.5, including the Threshold and Cap, will not apply with respect to Fraud or claims under Section 6.4(b), Section 6.4(c), or Section 6.4(d). 6.6 Indemnification as Exclusive Remedy. The indemnification provided in this ARTICLE VI, subject to the limitations set forth herein, will be the sole and exclusive post-Closing remedy available to the Buyer Indemnified Persons and the Seller Indemnified Persons in connection with any Losses arising out of or resulting from this Agreement, the transactions contemplated hereby, or Buyer’s ownership or operation of the Sold Assets, whether based in contract or tort (including negligence) or otherwise predicated on common law standards, strict liability or otherwise; provided, however, that the provisions of this Section 6.6 will not prevent or limit a cause of action at Law or in equity (a) for Fraud or (b) under Section 7.15 to obtain an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions hereof. Without limitation of any indemnification rights under this ARTICLE VI, the Buyer Indemnified Persons expressly waive any and all rights and remedies against the Seller under the Comprehensive Environmental Response, Compensation and Liability Act, 42 U.S.C. §9601 et seq. as amended, and other Environmental Laws in connection with any Losses arising out of or resulting from this Agreement, the transactions contemplated hereby, or the ownership or operation of the Sold Assets. 6.7 Indemnification Calculations. The amount of any Losses for which indemnification is provided under this ARTICLE VI will be computed net of any insurance proceeds actually paid to the Indemnified Party in connection with such Losses, minus any out-of-pocket expenses and attorney’s and other professional’s fees and expenses incurred relating to the recovery of such insurance proceeds including any increase in premiums (“Recovery Proceeds”). If an Indemnified Party receives Recovery Proceeds in connection with Losses for which it has received indemnification, and the result of which is that the Indemnified Party has received double recovery in respect of such Loss such Party will refund to the Indemnifying Party the amount of such Recovery Proceeds when received, up to the amount that is the lesser of the amount needed to avoid such double recovery or the amount paid by the Indemnifying Party. The Parties agree that any indemnification payments made pursuant to this Agreement shall be treated for tax purposes as an adjustment to the Purchase Price, unless otherwise required by applicable Law. 6.8 Notice and Opportunity to Defend. If there occurs an event which a Party asserts is an indemnifiable event pursuant to Sections 6.2 or 6.4, the Party seeking indemnification (the “Indemnified Party”) shall promptly notify the other Party obligated to provide indemnification (the “Indemnifying Party”) prior to the applicable Expiration Date, which notice shall specify the nature and basis of such claim and the amount thereof, to the extent known. If such event involves any claim or the commencement of any action or proceeding by a third Person (a “Third Party Claim”), the Indemnified Party will give such Indemnifying Party prompt written notice of such claim or the commencement of such action or proceeding, which notice shall specify the nature and basis of such claim and the amount thereof, to the extent known, and shall be accompanied by copies of all relevant documentation with respect to such claim, including any summons, complaint or 52 other pleadings that may have been served, any written demand or any other relevant document or instrument; provided, however, that the failure to provide such prompt notice will not relieve the Indemnifying Party of its obligations hereunder except to the extent such failure materially prejudices the Indemnifying Party hereunder. In the case of a Third Party Claim, the Indemnifying Party shall be entitled to assume the defense thereof, with counsel selected by the Indemnifying Party at its own expense, and, after notice from the Indemnifying Party to the Indemnified Party of such election to assume the defense thereof, the Indemnifying Party shall not be liable to the Indemnified Party for any legal expenses of other counsel or any other expenses subsequently incurred by such Indemnified Party in connection with the defense thereof. An election to assume the defense of such Third Party Claim shall, other than to the extent agreed otherwise by the Parties, be deemed an admission that the Indemnifying Party has an unqualified obligation to indemnify the Indemnified Party with respect to such Third Party Claim. The Indemnifying Party and the Indemnified Party agree to cooperate reasonably with each other and their respective counsel in connection with the defense, negotiation or settlement of any such Third Party Claim. Notwithstanding anything else set forth in this Section 6.8 to the contrary, the Indemnified Party shall at all times have the right to participate at its own expense in the defense of such action or asserted liability. If the Indemnifying Party assumes the defense of an action, no settlement or compromise thereof may be effected (a) by the Indemnifying Party without the prior written consent of the Indemnified Party (which consent shall not be unreasonably withheld, conditioned or delayed) unless the settlement involves solely money damages and all such relief is paid or satisfied in full by the Indemnifying Party or (b) by the Indemnified Party without the prior written consent of the Indemnifying Party (which consent shall not be unnecessarily withheld, conditioned or delayed). In no event shall any settlement be determinative of whether any Losses under such settlement are indemnifiable by an Indemnifying Party or the amount of such Losses without the Indemnifying Party’s prior written consent. 6.9 Satisfaction of Claims. Subject to the other applicable provisions regarding indemnification contained in this Article VI, if the Seller is obligated to reimburse or compensate the Buyer for any Losses in connection with a claim by a Buyer Indemnified Person under Section 6.2, then indemnification for such Losses shall, subject to the applicable limitations, if any, set forth in this Article VI, be satisfied at the election of Buyer (i) by reducing the principal amount of the Promissory Note then outstanding with such reduction deemed retroactive to the Closing Date or (ii) by wire transfer of immediately available funds to an account or accounts designated by the Indemnified Party. 6.10 Additional Limitations. (a) Except for Losses resulting from an action brought by a third party against a Buyer Indemnified Person or a Seller Indemnified Person, no Buyer Indemnified Person or Seller Indemnified Person shall be entitled to indemnification under this ARTICLE VI for punitive damages or for any Losses to the extent such Losses constitute consequential damages and were not a reasonably foreseeable result of any breach by a Party of any representation, warranty, covenant or agreement of this Agreement. 53 (b) Notwithstanding anything in this ARTICLE VI to the contrary, no Party shall be entitled to be compensated more than once for the same Loss. (c) Notwithstanding anything to the contrary contained in this Agreement, no Indemnifying Party shall be obligated to indemnify any Indemnified Party pursuant to Section 6.2 or Section 6.4 with respect to any Losses, to the extent (i) not relating to Taxes and arising as a result of any action or omission by any such Indemnified Party after the Closing, or (ii) such matter is the subject of any Ancillary Agreement and recourse is available pursuant thereto. (d) Subject to Section 6.9 of this Agreement, no Party shall be entitled to recover any indemnification payment or other amounts due from the other Parties under this Agreement by retaining and setting off the amounts (whether or not such amounts are liquidated or reduced to judgment) against any amounts due or to become due from such Party under this Agreement or under any document delivered pursuant hereto or in connection herewith, including any Ancillary Agreement. (e) Each of the Parties shall use commercially reasonable efforts to cooperate with each other to resolve any claim or liability with respect to which a Party is obligated to indemnify the other Party under this Agreement. 6.11 Certain Acknowledgements. The Parties unconditionally and irrevocably acknowledge and agree that (a) the terms of ARTICLE VI and ARTICLE VII are an integral part of this Agreement and the transactions contemplated by this Agreement, and (b) without the terms of ARTICLE VI and ARTICLE VII the Parties would not enter into this Agreement or otherwise agree to consummate the transactions contemplated by this Agreement. ARTICLE VII MISCELLANEOUS 7.1 Fees and Expenses. Except as otherwise provided in this Agreement, each Party shall be liable for and shall bear its own expenses and the expenses of its Affiliates in connection with the preparation and negotiation of this Agreement and the Ancillary Agreements and the performance and consummation of the transactions contemplated by this Agreement and the Ancillary Agreements. 7.2 Governing Law. This Agreement, and all claims or causes of action based upon, arising out of, or related to this Agreement or the transactions contemplated hereby, shall be governed by, and construed in accordance with, the Laws of the State of Delaware, without giving effect to principles or rules of conflict of laws to the extent such principles or rules would require or permit the application of Laws of another jurisdiction. The Parties agree that (a) the requirements of 6 Del. C. Section 2708 are satisfied and that the statute mandates the application of Delaware law to this Agreement, the relationship of the Parties, the transactions contemplated by this Agreement and the interpretation and enforcement of the rights and duties of the Parties, (b) no other jurisdiction has a materially greater interest in the foregoing, and (c) the application of 54 Delaware law would not be contrary to the fundamental policy of any other jurisdiction that, absent the Parties’ choice of Delaware law, would have an interest in the foregoing. 7.3 Further Acknowledgements. (a) In connection with the Buyer’s investigation of the Business and the Sold Assets, the Buyer or its Affiliates may have received from the Seller and its representatives certain projections and other forecasts for the Business, and certain business plan and budget information. The Buyer acknowledges that (i) there are uncertainties inherent in attempting to make such projections, forecasts, plans and budgets, (ii) the Buyer is familiar with such uncertainties, (iii) the Buyer is taking full responsibility for making its own evaluation of the adequacy and accuracy of all estimates, projections, forecasts, plans and budgets so furnished to it, and (iv) neither the Buyer nor any of its Affiliates will assert any claim against the Seller or any of its directors, officers, employees, Affiliates or representatives, or hold the Seller or any such Persons liable, with respect thereto.

3 any thereof, including interest thereon accruing after the commencement of any proceedings referred to in clause (a) below, whether or not such interest is an allowed claim in such proceeding, being hereinafter collectively referred to as “Senior Indebtedness”), until the discharge of such Senior Indebtedness has occurred: (a) in the event of any insolvency or bankruptcy proceedings, and any receivership, liquidation, reorganization or other similar proceedings in connection therewith, relative to the Maker or to its creditors, as such, or to its property, and in the event of any proceedings for voluntary liquidation, dissolution or other winding up of the Maker, whether or not involving insolvency or bankruptcy, then (x) the holders of Senior Indebtedness shall be paid in full in cash in respect of all amounts constituting Senior Indebtedness before the Payee is entitled to receive (whether directly or indirectly), or make any demands for, any payment on account of this Note and (y) until the holders of Senior Indebtedness are paid in full in cash in respect of all amounts constituting Senior Indebtedness, any payment or distribution to which the Holder would otherwise be entitled shall be made to the holders of Senior Indebtedness; and (b) after the occurrence of and during the continuation of an Event of Default, if all or any part of the assets of the Maker, or the proceeds thereof, are subject to any distribution, division or application to the creditors of the Maker, whether partial or complete, voluntary or involuntary, and whether by reason of liquidation, bankruptcy, arrangement, receivership, assignment for the benefit of creditors or any other action or proceeding, or if the business of the Maker is dissolved or if all or substantially all of the assets of the Maker are sold, then, and in any such event, any payment or distribution of any kind or character, whether in cash, securities or other investment property, or otherwise, which shall be payable or deliverable upon or with respect to any indebtedness of the Maker to the Payee shall be paid or delivered directly for application to any of the Senior Indebtedness, due or to become due. Except as otherwise set forth in clauses (a) and (b) of the immediately preceding paragraph, the Maker shall make payments to the Payee so long as no event of default shall have occurred and be continuing with respect to any Senior Indebtedness. If an event of default under the Senior Indebtedness has occurred and is continuing, Payee shall not demand, and Maker shall not make, any payments under this Note to Payee. (c) To the fullest extent permitted by law, no present or future holder of Senior Indebtedness shall be prejudiced in its right to enforce the subordination of this Note by any act or failure to act on the part of the Maker or by any act or failure to act on the part of such holder or any trustee or agent for such holder. (d) Notwithstanding the foregoing, nothing contained in the subordination provisions set forth above is intended to or will impair, as between the Maker and the Payee, the obligations of the Maker, which are absolute and 4 unconditional, to pay to the Payee the principal balance of this Note and all other amounts payable hereunder as and when due and payable in accordance with its terms, or is intended to or will affect the relative rights of the Holder and other creditors of the Payee other than the holders of Senior Indebtedness.

All references herein to the “Maker” and the “Payee” shall be deemed to apply to the Maker and the Payee, respectively, and to their respective permitted successors and assigns. 8. Interest Rate Limitation. Nothing contained in this Note or any transaction related to this Note, shall be construed or so operate as to require the Maker to pay interest at a greater rate than is now lawful or in such case to contract for, or to make any payment, or to do any act contrary to applicable law. Should any interest or other charges paid by the Maker, or parties liable for the payment of this Note, in connection with the indebtedness evidenced by this Note or any other document delivered in connection with this Note, result in the computation or earning of interest in excess of the maximum legal rate of interest that is legally permitted under applicable law, then any and all such excess shall be, and the same hereby is, waived by the Payee, and any and all such excess shall be automatically credited against and in reduction of the balance due under this Note, and the portion of said excess that exceeds the balance due under this Note shall be paid by the Payee to the Maker. 9. Cancellation. After all principal, premium and all other amounts at any time owed on this Note have been paid in full, this Note shall be surrendered to the Maker for cancellation. 10. Governing Law and Severability. The provisions of this Note shall be construed according to the internal substantive laws of the State of Delaware without regard to conflict of laws principles.
