If, at the end of such period, Seller and Buyer are unable to resolve any disagreements as to items in the Final Inventory Schedule, then the parties shall engage a nationally-recognized accounting firm (the “Auditor”) to resolve any remaining disagreements. The Auditor shall be charged with determining as promptly as practicable, but in any event within thirty (30) days after the date on which such dispute is referred to the Auditor, whether and to what extent the Final Inventory Schedule requires adjustment.

the year or period beginning after, the Closing Date shall be determined by assuming that the taxable year or period ended as of the close of business on the Closing Date, except that those annual property taxes and exemptions, allowances or deductions that are calculated on an annual basis shall be prorated on a time basis.

Section 9.2 Indemnification by Seller. Seller hereby agrees that from and after the Closing it shall indemnify, defend and hold harmless Buyer, its Affiliates, and their respective directors, officers, shareholders, partners, members, attorneys, accountants, agents, representatives and employees and their heirs, successors and permitted assigns, each in their capacity as such (the “Buyer Indemnified Parties” and collectively with Seller Indemnified Parties, the “Indemnified Parties”) from, against and in respect of any damages, losses, charges, liabilities, claims, demands, actions, suits, proceedings, payments, judgments, settlements, assessments, deficiencies, interest, penalties, and costs and expenses (including reasonable attorneys’ fees and out of pocket disbursements) (collectively, “Losses”) imposed on, sustained, incurred or suffered by, or asserted against, any of the Buyer Indemnified Parties, whether in respect of third party claims, claims between the parties hereto, or otherwise, directly or indirectly relating to or arising out of (i) any breach or inaccuracy of any representation or warranty made by Seller contained in Article III of this Agreement, (ii) any breach of any covenant or agreement of Seller contained in this Agreement or any Ancillary Agreement, (iii) any of the Excluded Liabilities, (iv) Seller’s operation of the Business prior to the Closing, or (v) any Taxes imposed with respect to the Business, any of the Purchased Assets or any of the Assumed Liabilities for any periods prior to the Closing.

Buyer hereby agrees that from and after the Closing it shall indemnify, defend and hold harmless Seller, its Affiliates, and their respective directors, officers, shareholders, partners, members, attorneys, accountants, agents, representatives and employees and their heirs, successors and permitted assigns, each in their capacity as such (the “Seller Indemnified Parties”) from, against and in respect of any Losses imposed on, sustained, incurred or suffered by, or asserted against, any of Seller Indemnified Parties, whether in respect of third party claims, claims between the parties hereto, or otherwise, directly or indirectly relating to, arising out of (i) any breach or inaccuracy of any representation or warranty made by Buyer contained in Article IV of this Agreement, (ii) any breach of a covenant or agreement of Buyer contained in this Agreement or any Ancillary Agreement, or (iii) any of the Assumed Liabilities.

Section 9.4 Third Party Claim Indemnification Procedures.

(a) In the event that any written claim or demand for which an indemnifying party (an “Indemnifying Party”) may have liability to any Indemnified Party hereunder is asserted against or sought to be collected from any Indemnified Party by a third party (a “Third Party Claim”), such Indemnified Party shall promptly, but in no event more than ten days

-29-

following such Indemnified Party’s receipt of a Third Party Claim, notify the Indemnifying Party in writing of such Third Party Claim and the amount or the estimated amount of damages sought thereunder to the extent then ascertainable (which estimate shall not be conclusive of the final amount of such Third Party Claim) (a “Claim Notice”); provided, however, that the failure timely to give a Claim Notice shall affect the rights of an Indemnified Party hereunder only to the extent that such failure has a material prejudicial effect on the defenses or other rights available to the Indemnifying Party with respect to such Third Party Claim or otherwise results in damages to the Indemnifying Party. The Indemnifying Party shall have 30 days (or such lesser number of days set forth in the Claim Notice as may be required by court proceeding in the event of a litigated matter) after receipt of the Claim Notice (the “Notice Period”) to notify the Indemnified Party that it desires to defend the Indemnified Party against such Third Party Claim; it being understood that by assuming the defense of a Third Party Claim the Indemnifying Party shall conclusively acknowledge that it has an indemnity obligation with respect to such Third Party Claim.

(b) In the event that the Indemnifying Party notifies the Indemnified Party within the Notice Period that it desires to defend the Indemnified Party against a Third Party Claim, the Indemnifying Party shall have the right to defend the Indemnified Party by appropriate proceedings and shall have the sole power to direct and control such defense, with counsel reasonably satisfactory to the Indemnified Party at its expense. Once the Indemnifying Party has duly assumed the defense of a Third Party Claim, the Indemnified Party shall have the right, but not the obligation, to participate in any such defense and to employ separate counsel of its choosing. The Indemnified Party shall participate in any such defense at its expense unless (i) the Indemnifying Party and the Indemnified Party are both named parties to the proceedings and counsel for the Indemnified Party shall have reasonably concluded that representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them, or (ii) the Indemnified Party assumes the defense of a Third Party Claim after the Indemnifying Party has failed to diligently pursue a Third Party Claim it has assumed, as provided in clause (i) of the first sentence of Section 9.4(c). The Indemnifying Party shall not, without the prior written consent of the Indemnified Party, settle, compromise or offer to settle or compromise any Third Party Claim on a basis that would result in (1) the imposition of a consent order, injunction or decree that would restrict the future activity or conduct of the Indemnified Party or any of its Affiliates, (2) a finding or admission of a violation of Law or violation of the rights of any Person by the Indemnified Party or any of its Affiliates, (3) a finding or admission that would have an adverse effect on other claims made or threatened against the Indemnified Party or any of its Affiliates, or (4) any monetary liability of the Indemnified Party that will not be promptly paid or reimbursed by the Indemnifying Party.

(c) The Indemnified Party shall have the right but not the obligation to assume its own defense if (i) the Indemnifying Party elects not to defend the Indemnified Party against a Third Party Claim, whether by not giving the Indemnified Party timely notice of its desire to so defend or notifying Indemnified Party that it will not provide a defense, (ii) the Indemnifying Party, after assuming the defense of a Third Party Claim, fails to take reasonable steps necessary to defend diligently such Third Party Claim within ten days after receiving written notice from the Indemnified Party to the effect that the Indemnifying Party has so failed, (iii) the claim for indemnification involves any criminal proceeding, indictment or allegation against the Indemnified Party, or (iv) the Indemnified Party has been advised by legal counsel that there may be one or more legal defenses available to it which are different from or additional to those

-30-

available to the Indemnifying Party; it being understood that the Indemnified Party’s right to indemnification for a Third Party Claim shall not be adversely affected by assuming the defense of such Third Party Claim. The Indemnified Party shall not settle a Third Party Claim without the consent of the Indemnifying Party, which consent shall not be unreasonably withheld.

(d) The Indemnified Party and the Indemnifying Party shall cooperate in order to ensure the proper and adequate defense of a Third Party Claim, including by providing access to each other’s relevant business records and other documents, and employees; it being understood that the out-of-pocket costs and expenses of the Indemnified Party relating thereto shall be Losses.

(e) The Indemnified Party and the Indemnifying Party shall use reasonable best efforts to avoid production of confidential information (consistent with applicable Law), and to cause all communications among employees, counsel and others representing any party to a Third Party Claim to be made so as to preserve any applicable attorney-client or work-product privileges.

Section 9.5 Direct Claims. If an Indemnified Party wishes to make a claim for indemnification hereunder for a Loss that does not result from a Third Party Claim (a “Direct Claim”), the Indemnified Party shall notify the Indemnifying Party in writing of such Direct Claim, the amount or the estimated amount of damages sought thereunder to the extent then ascertainable (which estimate shall not be conclusive of the final amount of such Direct Claim), any other remedy sought thereunder, any relevant time constraints relating thereto and, to the extent practicable, any other material details pertaining thereto. The Indemnifying Party shall have a period of 30 days within which to respond to such Direct Claim. If the Indemnifying Party does not respond within such 30-day period or rejects all or any part of the Direct Claim, the Indemnified Person shall be free to seek enforcement of its rights to indemnification under this Agreement with respect to such Direct Claim.

Section 9.6 Consequential Damages and Limitations. The parties acknowledge and agree that, except with respect to claims for fraud or willful misconduct, Losses exclude consequential, punitive, special, incidental and indirect damages, and lost profits, and that THE INDEMNIFICATION OBLIGATIONS OF THE PARTIES HERETO SHALL NOT EXTEND TO PUNITIVE LOSSES OR TO ANY INCIDENTAL, CONSEQUENTIAL, SPECIAL OR INDIRECT LOSSES, INCLUDING BUSINESS INTERRUPTION, LOSS OF FUTURE REVENUE, DIMINUTION IN VALUE, PROFITS OR INCOME, OR LOSS OF BUSINESS REPUTATION OR OPPORTUNITY; provided that nothing in this Section 9.6 shall preclude any recovery by an Indemnified Party against an Indemnifying Party for Third Party Claims.

(a) Indemnification for Losses under Section 9.2(i) or 9.3(i) shall be payable by Buyer or Seller hereunder only if the aggregate amount of all Losses hereunder of the Seller Indemnified Parties or the Buyer Indemnified Parties, as applicable, with respect to such Losses

-31-

shall exceed **, and thereafter, the Seller Indemnified Parties or the Buyer Indemnified Parties, as applicable, shall be entitled to make a claim for indemnification for all Losses from the first dollar. The maximum aggregate liability of the Buyer and Seller for indemnification claims for Losses under Section 9.2(i) or 9.3(i) shall be an amount equal to **; provided, however, that the limitations contained in this Section 9.6(b) shall not apply to claims for breach of Section 3.1, 3.2, 3.3, 3.9, the first two sentences of Section 3.10, Section 3.17, 4.1, 4.2 and 4.3 or actions for fraud or willful misconduct.

(b) Each party agrees that it shall, and shall cause the applicable Indemnified Parties to, use its or their commercially reasonable efforts to secure payment from insurance policies available and in existence that provide coverage with respect to any Losses to be indemnified. The amount of any Losses recoverable by a party under Article IX shall be reduced by the amount of any insurance proceeds actually paid to, and received by, the Indemnified Party relating to such claim. Each of the parties agrees to take all reasonable steps to mitigate damages arising out of or relating to any matter for which such party is entitled to indemnification under this Article IX to the extent reasonably possible.

(c) By way of clarification, for purposes of determining the amount of Losses imposed on, sustained, incurred or suffered by, or asserted against, any of the Buyer Indemnified Parties relating to or arising out of any breach or inaccuracy of any representation or warranty made by Seller contained in Article III of this Agreement (but not for purposes of determining whether any such representation and warranty was breached or is inaccurate), any qualifications in the representation or warranty relating to materiality (including, without limitation, a “Material Adverse Effect” qualification) shall be disregarded.

(d) Except for actions or claims for fraud or willful misconduct, the sole and exclusive remedy of each party for monetary damages with respect to any and all claims for any breach of any representation, warranty, covenant or other claim arising out of or relating to this Agreement, whether arising in contract, tort or otherwise, shall be the indemnification provisions of this Article IX, provided, however, that the provisions of this Article IX shall not restrict the right of any party to seek specific performance or other equitable remedies in connection with any breach of any of the covenants contained in this Agreement or any of the Ancillary Agreements.

Section 9.7 Payments. The Indemnifying Party shall pay all amounts payable pursuant to this Article IX, by wire transfer of immediately available funds, promptly following receipt from an Indemnified Party of a xxxx, together with all accompanying reasonably detailed back-up documentation, for a Loss that is the subject of indemnification hereunder, unless the Indemnifying Party in good faith disputes the Loss, in which event it shall so notify the Indemnified Party. In any event, the Indemnifying Party shall pay to the Indemnified Party, by wire transfer of immediately available funds, the amount of any Loss for which it is liable

**	REPRESENTS MATERIAL WHICH HAS BEEN REDACTED AND SEPARATELY FILED WITH THE SECURITIES AND EXCHANGE COMMISSION PURSUANT TO A REQUEST FOR CONFIDENTIAL TREATMENT PURSUANT TO RULE 406 UNDER THE SECURITIES ACT OF 1933, AS AMENDED.

-32-

hereunder no later than three days following any final determination of such Loss and the Indemnifying Party’s liability therefor. A “final determination” shall exist when (i) the parties to the dispute have reached an agreement in writing, (ii) a court of competent jurisdiction shall have entered a final and non-appealable order or judgment, or (iii) an arbitration or like panel shall have rendered a final non-appealable determination with respect to disputes the parties have agreed to submit thereto.

Section 9.8 Right of Setoff. Upon notice specifying in reasonable detail the basis therefor, either party may set off any amount to which the other may be entitled under this Article IX against amounts otherwise payable by such party under this Agreement or any Ancillary Agreement. The exercise of such right of setoff in good faith, whether or not ultimately determined to be justified, will not constitute a breach of this Agreement or the Ancillary Agreement, as applicable. Neither the exercise of nor the failure to exercise such right of setoff will constitute an election of remedies or limit such party in any manner in the enforcement of any other remedies that may be available to it.

Section 9.9 Effect of Waiver of Condition. Neither Buyer’s nor Seller’s right to indemnity pursuant to this Article IX shall be adversely affected by its waiver of a condition to closing set forth in Article VI unless such party makes clear by the terms of its waiver that it is foreclosing its right to indemnity with respect to the matter that is the subject of the waiver.
