            Re:   INITIAL PUBLIC OFFERING

Gentlemen:

            The  undersigned   stockholder,   officer  and  director  of  Ardent
Acquisition Corporation ("Company"), in consideration of EarlyBirdCapital,  Inc.
("EBC")  entering into a letter of intent  ("Letter of Intent") to underwrite an
initial public  offering of the securities of the Company  ("IPO") and embarking
on the IPO process,  hereby agrees as follows  (certain  capitalized  terms used
herein are defined in paragraph 11 hereof):

            1.  If  the  Company  solicits  approval  of its  stockholders  of a
Business Combination,  the undersigned will vote all Insider Shares owned by him
in  accordance  with the  majority  of the votes cast by the  holders of the IPO
Shares.

            2. In the event  that the  Company  fails to  consummate  a Business
Combination  within 18 months from the effective date ("Effective  Date") of the
registration statement relating to the IPO (or 24 months under the circumstances
described in the prospectus  relating to the IPO), the undersigned will take all
reasonable actions within his power to cause the Company to liquidate as soon as
reasonably practicable.  The undersigned hereby waives any and all right, title,
interest  or claim of any kind in or to any  distribution  of the Trust Fund (as
defined in the Letter of Intent) as a result of such liquidation with respect to
his Insider  Shares  ("Claim") and hereby waives any Claim the  undersigned  may
have in the  future  as a  result  of,  or  arising  out of,  any  contracts  or
agreements  with the Company and will not seek  recourse  against the Trust Fund
for any reason whatsoever. The undersigned agrees to indemnify and hold harmless

the Company, pro rata with the other officers and directors of the Company based
on the number of Insider  Shares held by each such  individual,  against any and
all loss, liability,  claims, damage and expense whatsoever (including,  but not
limited  to,  any and  all  legal  or  other  expenses  reasonably  incurred  in
investigating, preparing or defending against any litigation, whether pending or
threatened,  or any claim  whatsoever) which the Company may become subject as a
result  of any  claim by any  vendor or other  person  who is owed  money by the
Company for services  rendered or products sold, or by any target business,  but
only to the extent necessary to ensure that such loss, liability,  claim, damage
or expense does not reduce the amount in the Trust Fund.

            3. In order to minimize  potential  conflicts of interest  which may
arise  from  multiple  affiliations,  the  undersigned  agrees to present to the
Company for its  consideration,  prior to  presentation  to any other  person or
entity,  any suitable  opportunity to acquire an operating  business,  until the
earlier  of the  consummation  by the  Company of a  Business  Combination,  the
liquidation of the Company or until such time as the undersigned ceases to be an
officer  or  director  of the  Company,  subject to any  pre-existing  fiduciary
obligations the undersigned might have.

            4. The undersigned acknowledges and agrees that the Company will not
consummate any Business Combination which involves a company which is affiliated
with  any of the  Insiders  unless  the  Company  obtains  an  opinion  from  an
independent  investment  banking  firm  reasonably  acceptable  to EBC  that the
business  combination  is fair to the  Company's  stockholders  from a financial
perspective.

            5.  Neither  the  undersigned,  any  member  of  the  family  of the
undersigned,  nor any Affiliate of the  undersigned  will be entitled to receive
and will not accept any compensation for services  rendered to the Company prior
to the consummation of the Business Combination; provided that commencing on the
Effective Date, American Fund Advisors, Inc. ("Related Party"), shall be allowed
to charge the Company an  allocable  share of Related  Party's  overhead,  up to
$7,500 per month,  to compensate  it for the  Company's  use of Related  Party's
offices,  utilities and personnel.  Related Party and the undersigned shall also
be entitled to reimbursement from the Company for their  out-of-pocket  expenses
incurred in connection with seeking and consummating a Business Combination.

            6.  Neither  the  undersigned,  any  member  of  the  family  of the
undersigned,  or any Affiliate of the undersigned will be entitled to receive or
accept a finder's fee or any other  compensation  in the event the  undersigned,
any member of the family of the  undersigned or any Affiliate of the undersigned
originates a Business Combination.

period  commencing on the Effective  Date subject to the terms of a Stock Escrow
Agreement  which the Company will enter into with the  undersigned and an escrow
agent acceptable to the Company.
