                                    ONLINE, INC., a Delaware corporation (the
                                    "Corporation"), and GREENFIELD HOLDINGS,
                                    LLC, a Delaware limited liability company
                                    (the "Purchaser").

         WHEREAS, the Corporation desires to sell to the Purchaser and the
Purchaser desires to purchase from the Corporation (i) up to an aggregate of
$5,000,000 in principal amount of the Corporation's 10% subordinated promissory
notes and (ii) warrants to purchase shares of the Corporation's Class A Common
Stock, $0.01 par value per share (the "Class A Common Shares"), on the terms and
subject to the conditions set forth in this Agreement.

         NOW, THEREFORE, the parties hereto hereby agree as follows:

         Section 1. ISSUANCE OF THE NOTES AND THE WARRANTS.

         Upon the terms and subject to the conditions contained in this
Agreement, the Corporation has authorized the issuance to the Purchaser of, and
the Purchaser has committed to purchase from the Corporation, (a) up to
$5,000,000 (the "Total Commitment") in aggregate principal amount of its 10%
subordinated promissory notes (the "10% Notes") due on the date (the "Maturity
Date") which is the earlier to occur of (i) any Fundamental Change, Change of
Control or Liquidity Event and (ii) June 30, 2000, each such 10% Note to be
substantially in the form of EXHIBIT A attached hereto, and (b) warrants (the
"Warrants") to purchase up to 69,930 Class A Common Shares (the "Warrant
Shares"), each such Warrant to be substantially in the form of EXHIBIT B
attached hereto.

         Section 2. RESERVATION OF CLASS A COMMON SHARES.

         Upon the terms and subject to the conditions contained in this
Agreement, the Corporation shall reserve up to 69,930 Class A Common Shares for
issuance upon exercise of the Warrants.

         Section 3. SALE AND PURCHASE OF NOTES AND WARRANTS.

         At each Closing (as defined herein), the Corporation shall sell to the
Purchaser, and the Purchaser shall purchase from the Corporation, upon the terms
and subject to the conditions set forth herein 10% Notes in the aggregate
principal amount to be funded at such Closing as requested by the Corporation in
a written request for funding pursuant to Section 4(a). At the Initial Closing
(as defined herein), the Corporation shall sell to the Purchaser, and the
Purchaser shall purchase from the Corporation, a Warrant to purchase that number
of Warrant Shares as may be determined by dividing $500,000 by the Exercise
Price. Anything contained in the Financing Documents to the contrary
notwithstanding, in no event shall the Purchaser be obligated to purchase an
aggregate principal amount of 10% Notes in excess of the Total Commitment. The
Corporation and the Purchaser agree that 99.5% of the aggregate purchase price
to be paid by the Purchaser for the 10% Notes and the Warrants shall be
allocated to the sale and purchase of the 10% Notes. No party hereto shall take
a position inconsistent with this allocation unless otherwise required by law.

                                    among GREENFIELD ONLINE, INC., a Delaware
                                    corporation (the "Borrower"), and GREENFIELD

terms shall be accorded the definitions assigned to them in the Purchase
Agreement.

               2.1. Section 1 of the Purchase Agreement is hereby amended by
deleting the reference to "June 30, 2000" in subclause (ii) of clause (a)
thereof and replacing it with "June 30, 2001".

               2.2. The Purchase Agreement is hereby amended by adding a new
Section 4A thereto to read in its entirety as follows:

                  "Section 4A. Contingent Right To Additional Warrants.

                  Notwithstanding anything to the contrary contained in the
                  Financing Documents, if the Corporation has not repaid all of
                  the principal and interest due on the 10% Notes on or prior to
                  each date set forth below, then, not later than the fifth
                  business day following such date, the Corporation shall issue
                  to the Purchaser additional warrants (the "Contingent
                  Warrants") to purchase the number of Class A Common Shares (as
                  such number of Class A Common Shares may be adjusted for stock
                  splits, stock dividends, split ups, combinations,
                  reclassifications of Class A Common Shares, capital
                  reorganizations, mergers or consolidations and other similar
                  events) set forth opposite the corresponding date below (each
