          AMENDMENT TO THE AMENDED AND RESTATED START PAGE AGREEMENT

         This Amendment to the Amended and Restated Start Page Agreement (the
"Amendment") is made and entered into effective as of July 1, 2000 (the
"Amendment Effective Date") and is made by and between NetZero, Inc., a
Delaware corporation ("NetZero"), and LookSmart, Ltd., a Delaware corporation
("LookSmart"), and modifies that certain Amended and Restated Start Page
Agreement by and between NetZero and LookSmart dated February 1, 2000 (the
"Agreement"). Except as expressly modified herein, the Agreement shall remain

herein shall have the meanings set forth in the Agreement.

                                 Recitals

         WHEREAS, pursuant to the Agreement, the parties have previously
utilized a certain process pursuant to which NetZero requests LookSmart
services;

         WHEREAS, pursuant to the Agreement, the parties utilize a payment
methodology pursuant to which LookSmart pays NetZero for each such service
provided that qualifies as a Referral;

         WHEREAS, during the time the Agreement has been effective, including
predecessor agreements, the parties have relied upon LookSmart's calculation
of the number of Referrals which was based on NetZero's requests to
LookSmart's web page server and/or ad server;

         WHEREAS, shortly after the Effective Date of the Agreement, the
parties mutually implemented a new process pursuant to which NetZero serves
the Co-Branded Start Page;

         WHEREAS, due to the difficulties in tracking which Referrals are
billable and non-billable, the parties desire to change the payment structure
for Referrals to eliminate the concept of non-billable Referrals and to make
an appropriate adjustment to Referral pricing;

         NOW, THEREFORE, the parties agree as follows:

1.       As of July 1, 2000, the first sentence of Section 2(b) of the
Agreement, shall be deleted in its entirety and replaced with the following
language:

         "LookSmart shall pay to NetZero [**********] per 1000 Referrals
(collectively, "CPM REVENUES")."

2.       As of July 1, 2000, the fourth sentence of Section 2(b) of the
Agreement shall be deleted in its entirety and replaced with the following
language:

         "For the purposes of this Agreement, a "Referral" shall mean each
         request sent from NetZero to LookSmart's ad servers (each, an "Ad
         Request") as tracked by LookSmart in a manner consistent with the
         method LookSmart has historically tracked Ad Requests.  NetZero
         agrees that it will not create any new features that are designed to
         significantly increase the number of Referrals generated during a
         particular Subscriber session in excess of the number of Referrals
         (using the definition of Referrals set forth herein) that would have
         been generated during a similar Subscriber session prior to the
         Amendment Effective Date, except that NetZero may develop and
         implement processes which are specifically intended to decrease the
         load time of the Co-Branded Start Page.  LookSmart agrees that it
         will not alter the Co-Branded Services to eliminate the tags or
         links that generate Ad Requests.  In the event that LookSmart's ad
         servers or tracking methodology are malfunctioning, defective or
         otherwise incorrectly tracking Ad Requests, the parties shall work
         together in good faith to cure such deficiency and to reconcile the
         number of Referrals."

3.       The parties agree that all past accounting for Referrals through
June 30, 2000, as contained in LookSmart's confirmations, conforms to the
Agreement and is accurate and complete, and that NetZero has relied upon such
confirmations to account for Referrals during such period.  LookSmart agrees
that pursuant to such accounting it shall pay NetZero for an estimated
[********] Referrals in June 2000 at [****] per Referral, where such number of
Referrals for June 2000 shall be subject to good faith final adjustment.

This Agreement has been executed to be effective as of the date first written
above.
