                   AMENDMENT NO. 1 TO ASSET PURCHASE AGREEMENT


                      THIS AMENDMENT NO. 1 TO ASSET PURCHASE AGREEMENT (this
"AMENDMENT") is made as of March 16, 2001, between E-CENTIVES, INC., with
offices at 6901 Rockledge Drive, 7th Floor, Bethesda, Maryland 20817 (the
"BUYER") and INKTOMI CORPORATION, with offices at 4100 East Third Avenue, Foster
City, CA 94404 (the "SELLER," and together with the Buyer, the "PARTIES").
Capitalized terms not defined herein shall have the meaning assigned to such
terms in the Asset Purchase Agreement (as defined below).


                                   WITNESSETH:

                      The Parties are parties to that certain Asset Purchase
Agreement dated as of January 18, 2001 (the "ASSET PURCHASE AGREEMENT"),
pursuant to which the Parties have agreed to certain conditions and restrictions
relating to a transaction in which the Buyer will purchase all of the assets
(and assume certain of the liabilities) of the Commerce Product Business unit of
the Seller in return for shares of common stock of the Buyer.

                      The Parties agree as follows:

                      Extension of Termination Date. Sections 9(a)(ii) and (iii)
of the Asset Purchase Agreement governing termination are hereby deleted in
their entirety and are amended to read in their entirety as follows:


                  (iv) the Buyer may terminate this Agreement by giving written
        notice to the Seller at any time prior to the Closing (A) if any of the
        conditions set forth in Section 7(a) of this Agreement shall have become
        incapable of fulfillment and shall not have been waived by the Seller,
        or (B) if the Closing shall not have occurred on or before March 23,
        2001, by reason of the failure of any condition precedent under Section
        7(a) hereof (unless the failure results primarily from the Buyer itself
        breaching any representation, warranty, or covenant contained in this
        Agreement); or

                  (v) the Seller may terminate this Agreement by giving written
        notice to the Buyer at any time prior to the Closing (A) if any of the
        conditions set forth in Section 7(b) of this Agreement shall have become
        incapable of fulfillment and shall not have been waived by the Seller,
        or (B) if the Closing shall not have occurred on or before March 23,
        2001, by reason of the failure of any condition precedent under Section
        7(b) hereof, unless the failure results primarily from the Seller itself
        breaching any representation, warranty, or covenant contained in this
        Agreement.
