                          Full-Recourse Promissory Note

$56,285                                                            March 9, 2001


            FOR VALUE RECEIVED, Hugh Davis (the "Maker"), hereby promises to pay
to GREENFIELD ONLINE, INC. (the "Payee"), the principal amount of Fifty-Six
Thousand Two Hundred Eighty-Five Dollars ($56,285) on the earlier to occur of:
(i) a "Change of Control of the Payee" (defined below) or (ii) 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 8% 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 12% 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. A "Change of Control of the Payee" shall be
deemed to have occurred upon the occurrence of a "Sale of the Corporation" as
such term is defined in the Payee's Restated Certificate of Incorporation filed
on or about the date hereof.

            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 (with any such
prepayment amount applied first to the payment of interest and then to the
repayment of principal).

            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 Connecticut.

      interest on this Note, when and as the same shall become due and payable,

      acceleration hereof or otherwise;

                  (ii) the Maker shall (A) apply for or consent to the

      allegations of a petition filed against him in any proceeding under any
      such law;

                  (iii) an order, judgment or decree shall be entered, without
      the application, approval or consent of the Maker, by any court of
      competent jurisdiction, approving a petition seeking reorganization of the
      Maker, or appointing a receiver, trustee or liquidator for the Maker;

                  (iv) the Maker shall become or be in default under the
      provisions of (A) this Note, (B) the Pledge Agreement or the Employment
      Agreement dated as of May 17, 1999, between the Maker and the Payee, in
      each case as the same may hereafter be amended and in effect from time to
      time, or (C) any other material agreement between the Maker and the Payee
      or any of its affiliates or between the Maker and the holder hereof or any

this Note may, upon written notice to the Maker or his estate or executor,
declare this Note to be forthwith due and payable, whereupon this Note shall
become forthwith due and payable, both as to principal and interest, without
presentment, demand, protest, or other notice of any kind, all of which are
hereby expressly waived, and (2) in the case of clauses (ii) and (iii) of this
Note, this Note shall forthwith become due and payable both as to principal and
interest, automatically without any action on the part of the holder hereof and
without presentment, demand, protest, or other notice of any kind, all of which
are hereby expressly waived. In addition, at any time after the earlier to occur
of: (i) the Maturity Date and (ii) the occurrence of an Event of Default, the
Payee shall be entitled, to the maximum extent permitted under applicable law,
to offset any amount due and

                                       2

owing to it hereunder against any amount payable on or after such time by the
Payee to the Maker.

            The Payee hereby acknowledges and agrees that if the Pledged
Collateral (as defined in the Pledge Agreement) is insufficient to satisfy the
Maker's obligations to the Payee pursuant to this Note and the Pledge Agreement,
the Payee shall have full recourse to the assets of the Maker legally available
for repayment of creditors.

            The provisions hereof shall be binding upon and inure to the benefit
of the holder of this Note and its successors and assigns. This Note may not be
assigned or transferred by the Maker.

            The Maker agrees to pay all costs of collection, including
reasonable attorneys' fees, incurred by the holder of this Note in collecting or
enforcing this Note, whether in connection with a reorganization, bankruptcy or
other similar proceeding or upon default.
