Purchase Price shall be payable by means of a  nonrefundable  credit in favor of

2.  Investment  Option.  Pursuant  to  Section  2.3 of the  Securities  Purchase
Agreement, ValueStar is authorized to issue and sell additional shares of Series
CC Stock, up to a maximum  aggregate total of 500,000 shares  (including  shares
issued  at  the  Initial   Closing  (as  defined  in  the  Securities   Purchase
Agreement)). ValueStar hereby agrees to reserve, and grants FDMS or an Affiliate
(as defined in the  Development  Agreement)  designated by FDMS, the option (the
"Option") to  purchase,  for cash up to 177,778  additional  shares of Series CC
Stock and related warrants on the same terms as are set forth in Section 1 above
and the Securities Purchase Agreement up and to the date of March 31, 2001. This
Option may be exercised only one time and in a minimum of $1,000,000.

3. Marketing Exclusivity. Except for Union Bank, for a period of six months from
the  date of this  Agreement,  ValueStar  and its  Subsidiary  shall  not sign a
marketing  agreement  with a merchant bank which is not an FDMS Bank (as defined
in the Development Agreement). Except for First National Bank of Omaha and MBNA,
for a period of six months from the date of this  Agreement,  ValueStar  and its
Subsidiary  shall not sign a marketing  agreement  with an issuing bank which is
not an FDMS Bank or FDR Issuer  (as  defined in the  Strategic  Development  and
Marketing  Agreement dated November 1, 2000 between First Data  Resources,  Inc.
and ValueStar).

4. Director  Appointment.  So long as FDMS and/or its Affiliate own at least 50%
of the  securities  described in Section 1 hereof and purchased  pursuant to the
Securities  Purchase  Agreement  (assuming the exercise of Warrants and adjusted
for stock splits,  combinations,  dividends  and the like),  FDMS shall have the
right, but not the obligation, to designate a nominee,  reasonably acceptable to
the Board of  Directors of  ValueStar,  to be elected as a director of ValueStar
and shall  promptly  notify  ValueStar  of such  designee.  Upon receipt of such
notice,  ValueStar  shall cause FDMS's  nominee to be placed on the slate at the
next annual or special  meeting of  stockholders of the Company for the election
of directors (and each annual or special meeting  thereafter for the election of
directors pursuant to this clause) and shall use its reasonable efforts to cause
such nominee to be elected at such meeting of  stockholders.  If FDMS elects not
to designate a nominee for director,  or if FDMS's nominee is not elected to the
Board of Directors,  FDMS, so long as it is entitled to nominate a nominee for a
directorship  may designate one individual  (the "FDMS  Observer") to attend all
meetings of ValueStar's  Board of Directors  (and any  committees  thereof) in a
non-voting observer capacity. The FDMS Observer shall be entitled to receive all
reports,  presentations  and materials as if such FDMS Observer were a member of
the Company's Board of Directors.  Expenses of attending  meetings shall be paid
by FDMS except  that any FDMS  nominated  director  shall be entitled to receive
directors  fees  and  expense   reimbursement  payable  to  other  directors  of
ValueStar.  Notwithstanding  the  foregoing,  (a)  in the  event  the  Board  of
Directors  intends  to  discuss  or vote  upon any  matter  that is  subject  to
attorney-client  privilege,  or otherwise  involves  confidential or proprietary
information of ValueStar,  the FDMS Observer may be excluded from the portion of
the meeting at which such matter is  discussed  by the vote of a majority of the
directors  present,  and (b) in the event FDMS or any of its  Affiliates  or its
representatives  becomes a direct  competitor of ValueStar,  the Chairman of the
Board of Directors or a majority of the  directors  present may exclude the FDMS
Observer from the meetings of the Board of Directors.
