Notwithstanding the foregoing, the Shareholder's obligation to Indemnify Buyer Indemnified Parties shall not be reduced, offset or adversely affected, in whole or in part, because of the negligence or alleged negligence of Buyer on or prior to the date hereof in investigating or evaluating the Companies in contemplation of the consummation of the transactions contemplated by this Agreement or because of the negligence, alleged negligence or strict liability of the Companies on or prior to the date hereof. 6.3 Notice. (a) As used in this Section 6.3, the term "Indemnified Party" shall mean any Seller Indemnified Party or any Buyer Indemnified Party, as the case may be, which is asserting a claim for indemnity hereunder. Any party against whom a claim for indemnification is asserted by an Indemnified Party pursuant to this Article VI is referred to herein as an "Indemnifying Party." In the event that any Claim (a "Third Party Claim") is asserted against or sought to be collected from an Indemnified Party by a person who is not a Buyer Indemnified Party or a Seller Indemnified Party (a "Third Party"), such Indemnified Party shall give prompt notice to the Indemnifying Party of such event ("Claim Notice"). A Claim Notice shall specify, to the extent known by the Indemnified Party, the nature of and specific basis for any Claims or the nature of and specific basis of any suit, action, investigation or proceeding set forth therein and the amount or the estimated amount thereof to the extent then practicable. Any failure on the part of any Indemnified Party promptly to provide a Claim Notice to the Indemnifying Party shall relieve the Indemnifying Party of such party's obligation under this Article VI only to the extent that the Indemnifying Party has been prejudiced by the lack of timely and adequate notice to the Indemnifying Party. (b) The Indemnifying Party shall have 30 days from the delivery or receipt of a Claim Notice ("Notice Period") to notify the Indemnified Party (i) whether or not it disputes the liability of the Indemnifying Party to the Indemnified Party hereunder with respect to the Claims identified in the Claim Notice, and (ii) whether or not it desires to assume the defense of the Third Party Claim identified in the Claim Notice; provided, however, that any Indemnified Party is hereby authorized during the Notice Period to file any motion, answer or other pleading that shall be necessary or appropriate to protect its interests or those of the Indemnifying Party. In the event that the Indemnifying Party notifies the Indemnified Party within the Notice Period that it desires to defend the Indemnified Party against the Claim identified in the Claim Notice, the Indemnifying Party shall have the right and obligation, at its sole cost and expense, to defend with counsel of its own choosing by all appropriate proceedings, which proceedings shall be properly and diligently settled or prosecuted to a final non-appealable order of a court of competent jurisdiction; provided, however, that (a) the Indemnified Party shall at all times have the right, at its sole option and expense, to employ separate counsel and to participate fully in the defense, compromise or settlement thereof, and (b) if the Indemnifying Party does not proceed diligently to defend the Claim within 30 days after personal delivery or receipt of a Claim Notice, the Indemnified Party shall have the right, but not the obligation, to undertake the defense of any such Claim and the Indemnifying Party shall be bound by any defense or settlement that the Indemnified Party may make as to such Claim. Upon its assumption of the defense of any such Claim, the Indemnifying Party shall have full control of such defense and proceedings including any compromise or settlement thereof. 15 If there is more than one Indemnifying Party, then all Indemnifying Parties must coordinate the defense of the Indemnified Party against any Claims so as not adversly to affect the Indemnified Party's right to a proper defense. (c) The parties agree reasonably to cooperate with one another and their respective counsel in contesting and defending any Third Party Claim (including granting reasonable access to the pertinent books, records and personnel in their possession or control, or in the possession or control of the Companies) or, if appropriate and related to the Claim in question, in making (i) any counterclaim against the Third Party asserting the Claims, or (ii) any cross complaint against any person. (d) Notwithstanding anything in this Section 6.3 to the contrary, the Indemnifying Party shall not, without the written consent of the Indemnified Party (i) settle or compromise any Claim or consent to the entry of any judgment with respect to such Claim that does not include as an unconditional term thereof the delivery by the claimant or plaintiff to the Indemnified Party of a written release from all liability in respect to such Claim, (ii) settle or compromise any Claim in any manner that may materially and adversely affect the Indemnified Party, or (iii) settle or compromise any Claim in a manner that will require the Indemnified Party to pay any money. (e) If the Indemnifying Party fails to notify the Indemnified Party within the Notice Period that the Indemnifying Party elects to defend the Indemnified Party pursuant to Section 6.3(b), or if the Indemnifying Party elects to defend the Indemnified Party pursuant to Section 6.3(b), but fails diligently and promptly to prosecute, defend or settle any Third Party Claim, then the Indemnified Party shall have the right to defend, or compromise and settle at the sole cost and expense of the Indemnifying Party, the Third Party Claim by all appropriate proceedings, which proceedings may be prosecuted by the Indemnified Party to a final non-appealable order of a court of competent jurisdiction or settled without the consent of the Indemnifying Party. The Indemnified Party shall have full control of such defense and proceedings. (f) In the event any Indemnified Party should have a Claim against any Indemnifying Party hereunder that does not involve damages being asserted against or sought to be collected from it by a Third Party, the Indemnified Party shall send a Claim Notice containing the same type of information required by Section 6.3(a) with respect to such Claim to the Indemnifying Party. If the Indemnifying Party does not notify the Indemnified Party within the Notice Period that it disputes such Claim, the amount of such damages shall (unless it shall not have been reasonably practicable for the Indemnifying Party to give such notification) be conclusively deemed a liability of the Indemnifying Party hereunder. 6.4 Indemnification Rights. Other than any right to sue for fraud, the indemnification rights provided for in this Article VI are the sole remedy of either party in respect of any breach of representation, warranty, covenant or agreement contained in this Agreement. 6.5 Limitation of Liability. Notwithstanding any other provision hereof, (i) the Shareholder shall have no liability for any breaches of any representation or warranty as a result of a circumstance or fact of which the Shareholder shall have been unaware and should not reasonably have been aware unless the aggregate liabilities for all such breaches exceeds $10,000, and (ii) the aggregate liability of the Shareholder for all breaches shall not exceed the aggregate purchase price referred to in Section 2.2. 16 6.6 Survival. The rights of Buyer to give a Claim Notice pursuant to Section 6.3(a) or Section 6.3(f), as the case may be, or to initiate any action in respect of any Claim (including a Third Party Claim) shall survive the Closing until the close of business on the date that is the earlier to occur of (i) three business days prior to the date of the holding of a shareholders' meeting of the Shareholder called for the purposes of approving a sale of stock of the Shareholder, the sale of substantially all assets of the Shareholder, any merger of the Shareholder with one or more other entities, any transaction involving exchange of securities for all the stock of the Shareholder, or any other transaction relating to the change of control of the Shareholder, (provided, always, that such transaction is approved at such meeting) and (ii) the date that is one year after the date hereof (other than in relation to the representations and warranties contained in Sections 3.1, 3.2, 3.3 and 3.11, where such right shall survive until the expiration of the applicable statute of limitations). Buyer agrees to make available to the Shareholder and its counsel, and to other parties involved in any transaction referred to above and their counsel, the minute books (including share ledger and register) of each of the Companies from time to time following the Closing (including, after the earlier of the dates in subparagraphs (i) and (ii) above) during business hours and on reasonable notice.
