         a)       Excite currently plans to develop a consumer packaged goods                   (CPG) program that would combine the broad reach of the                   Excite Network with the depth of CPG merchants' industry





                  contacts and sales staffs. Under this program, Excite and                   each CPG merchant would develop co-branded Web pages on the                   Excite Network that would promote the merchant's goods cr                   provide content of interest to Excite's users. Excite would                   run dual promotional efforts, one that sends consumers to                   each CPG merchant's co-branded area and a second that sends                   consumers to the portion of the Excite Network that promotes                   the entire CPG program. Excite and NetGrocer agree to                   negotiate in good faith to establish the terms and conditions                   for NetGrocer's participation in Excite's CPG program when                   and if launched.

         b)       Excite currently plans to make available sponsorship                   opportunities on its WebCrawler Site (located at                   http://www.webcrawler.com) generally similar to the                   opportunity described by this Agreement, with the significant                   exception that merchants will not be granted category                   exclusivity or rights to exclude competitors on the                   WebCrawler Site. Excite and NetGrocer agree to negotiate in                   good faith to establish the terms and conditions for                   NetGrocer's participation in available sponsorship                   opportunities on the WebCrawler Site when and if launched.
