            The  undersigned   stockholder  of  Ardent  Acquisition  Corporation

hereby agrees as follows (certain  capitalized  terms used herein are defined in

kind in or to any  distribution of cash,  property or other assets ("Fund") as a
result of such  liquidation  with respect to his Insider  Shares  ("Claim")  and
