      FOR VALUE RECEIVED, Hugh Davis (the "Maker"), hereby promises to pay to
GREENFIELD ONLINE, INC. (the "Payee"), the principal amount of Seventy Five
Thousand Thirteen Dollars ($75,013) on May 17, 2004 (the "Maturity Date"), in
such coin or currency of the United States of America as at the time of payment
shall be legal tender therein for the payment of public and private debts, and
to pay interest on the unpaid principal amount from time to time outstanding
hereunder at the rate of 5.3% per annum, compounded annually based on a year of
360 days. Such interest shall be payable together with principal, when and as
paid, with the final payment of interest to be payable together with all
outstanding principal hereunder on the Maturity Date. In addition, the Maker
promises to pay additional interest at 7.3% per annum on any overdue principal
and (to the extent permitted by law) on any overdue interest, from the due date
thereof until the obligation of the Maker with respect to the payment thereof
shall be discharged.

      The Maker may, at his sole option, at any time and from time to time
prepay this Note, without penalty, in whole or in part, together with interest
on the principal amount so prepaid to the date of such prepayment.

      The Maker shall make a mandatory prepayment (each, a "Mandatory
Prepayment") in an amount equal to 100% of any and all dividends, distributions
and other payments (including the proceeds of any sale, transfer or other
disposition) paid on or with respect to the Pledged Collateral securing this
Note pursuant to the Pledge Agreement dated as of the date hereof between the
Maker and the Payee (as amended, the "Pledge Agreement"). Each such Mandatory
Prepayment shall be due and payable immediately upon receipt thereof by the
Maker and shall be applied first to interest on this Note accrued and unpaid as
of the date of the Mandatory Prepayment and then to the principal amount of this
Note then outstanding.

      The Payee shall be entitled to the rights and security granted by the
Maker to the Payee pursuant to the Pledge Agreement.

      Payment of both the principal of and interest on this Note shall be made
by check mailed to such office as the holder of this Note shall designate in
writing to the Maker.

      Should the principal of or interest on this Note become due and payable on
other than a business day, the maturity thereof shall be extended to the next
succeeding business day, and interest shall be payable thereon at the rate per
annum herein specified during such extension. The term "business day" shall mean
any day that is not a Saturday, Sunday or legal holiday in the State of New
York.
