If (i) the Company and Newco have not entered into a definitive agreement with respect to the Transaction by September 30, 1997, (ii) such definitive agreement is terminated in accordance with its terms, or (iii) the Company releases any of the Shareholders from his or her obligations under this Agreement (with any transfer made in compliance with paragraph 2(b) above not being deemed such a release), then this Agreement shall expire and all further obligations of the parties hereto shall terminate.
