The Purchase Price will be adjusted at Closing as required to prorate taxes for the current year.

Such access shall be provided by Seller to an independent auditing firm selected by Buyer subject to the entering by the auditing firm of a confidentiality agreement reasonably required by Seller. Seller shall not be required to provide direct access to Seller’s records to Buyer or any employees, consultants or other representatives of Buyer.

8.4

Notice and Cooperation. If a Claim is asserted against a Party for which the Party would be liable under the provisions of this Section, it is a condition precedent to the indemnifying Party’s obligations hereunder that the indemnified Party gives the indemnifying Party written notice of such Claim setting forth full particulars of the Claim, as known by the indemnified Party, including a copy of the Claim (if it was a written Claim). The indemnified Party shall make a good faith effort to notify the indemnifying Party in writing within one (1) month of receipt of a Claim and shall in all events effect such notice within such time as will allow the indemnifying Party to defend against such Claim and no later than three (3) calendar months after receipt of the Claim by the indemnified Party.

In such event, the indemnified Party shall send a written notice to the indemnifying Party of any proposed settlement of any Claim, which settlement the indemnifying Party may accept or reject, in its reasonable judgment, within thirty (30) days of receipt of such notice, unless the settlement offer is limited to a shorter period of time in which case the indemnifying Party shall have such shorter period of time in which to accept or reject the proposed settlement. Failure of the indemnifying Party to accept or reject such settlement within the applicable time period shall be deemed to be its rejection of such settlement. The indemnified Party may settle any matter over the objection of the indemnifying Party but shall in so doing be deemed to have waived any right to indemnity therefor as to (and only as to) liabilities with respect to which the indemnifying Party has recognized its liability.

(a)

No suit, action or other proceedings shall be pending before any court or governmental entity in which it is sought by a person or entity other than the Parties hereto or any of their Affiliates, officers, directors, or employees to restrain, enjoin or otherwise prohibit the consummation of the transactions contemplated by this Agreement, or to obtain substantial damages in connection with the transaction contemplated herein, nor shall there be any investigation by a governmental entity pending which might result in any such suit, action or other proceedings seeking to restrain, enjoin or otherwise prohibit the consummation of the transaction contemplated by this Agreement;

By either Seller or Buyer pursuant to any express rights to terminate hereunder; and

(d)
