Stockholder shall keep Purchaser reasonably

apprised on a reasonably prompt basis as to the status of any such discussions and/or negotiations and shall promptly (within 48 hours) provide to Purchaser copies of any material written communications delivered or received by Stockholder in connection with such discussions and/or negotiations.

Without limiting the foregoing and subject to Section 9 hereto, it is understood that except as and to the extent set forth in clause (a) above, the obligations under this Section 3 shall not be affected by any Adverse Recommendation Change or other recommendation or position of the Seller’s Board of Directors.
