| IMPORTANT INFORMATION ON THE STATUS OF THE CMGI DIRECTED SHARE PROGRAM FOR ALTAVISTA COMPANY
 
 August 25, 2000
 
 Dear CMGI Directed Share Program Registrant:
 
 Wit SoundView, the administrator of the CMGI Directed Share Program
 for AltaVista Company, has formed a strategic alliance with E*TRADE
 designed to combine Wit SoundView's expertise in investment banking
 and research with the online brokerage expertise of E*TRADE.  This
 letter describes the effect of this strategic alliance upon the
 administration of the CMGI Directed Share Program and in, particular,
 for the AltaVista Company ("AltaVista") Initial Public Offering.  As
 you know, the Initial Public Offering ("IPO") for AltaVista has been
 postponed due to market conditions and at this time we do not have any
 information as to when or if this offering will occur in the future.
 
 As a result of this strategic alliance with E*TRADE, your account with
 Wit Capital will automatically be transferred to E*TRADE unless you
 inform Wit Capital to the contrary.  If you choose not to have your
 account automatically transferred to E*TRADE you will not be able to
 participate in the CMGI Directed Share Program for AltaVista.  Details
 regarding the account transfer, as well as your new E*TRADE account
 number, username and password are being sent to you via U.S. mail in
 an E*TRADE Welcome Kit over the next few weeks.  The transfer of
 accounts, as well as the transfer of all securities and cash balances
 in Wit Capital accounts, is scheduled to occur on or about September
 30, 2000.
 
 The account transfer WILL NOT impact your registration in the CMGI
 Directed Share Program for AltaVista.  If you already have an E*TRADE
 account, a second E*TRADE account will be opened for you.   You will
 need to maintain a separate E*TRADE account in order to identify you
 as part of the CMGI Directed Share Program for AltaVista once the
 transition to E*TRADE is completed.
 
 In the event that AltaVista re-initiates its efforts to complete an
 IPO you will be notified of any further action required on your behalf
 by the Program administrators.  Please continue to regularly monitor
 your computer for emails from Wit SoundView, the administrator of the
 CMGI Directed Share Program.   Regular updates to the Program and
 additional questions and answers relating specifically to the
 AltaVista offering can be found at
 affinity.witcapital.com and www.cmgi.com.  All email
 inquiries should be sent to altavista@witcapital.com.
 
 We look forward to corresponding with you further as details become
 available.
 
 Sincerely,
 
 CMGI Directed Share Program Team
