Attention: Bob Saunders


Dear Bob:

     Previously, Microsoft Corporation ("Microsoft") and High Speed Access Corp.
(HSA) entered into a letter agreement setting forth a statement of the
intentions of the parties with respect to a strategic relationship and related
arrangements as outlined therein (the "Original Letter Agreement"). The parties
acknowledge that such proposals are subject to the final negotiation and
execution of definitive documents.

     In continuing our discussions, Microsoft has agreed to accelerate
discussions regarding the negotiation and execution of definitive agreements on
the proposals set forth in the Original Letter Agreement to occur within the
next six months. Further, Microsoft has agreed that HSA shall have the right to
purchase commercially available Microsoft products and technology at preferred
pricing consistent with other "strategic partners" of Microsoft, considering
such factors as volume of purchases, class of customer utilizing the software,
the type of software used and distribution channel.

     In consideration of the foregoing, HSA will promptly upon signing this
letter grant Microsoft a warrant to purchase 137,500 shares of HSA common stock
at a price of $16.25 per share. The form of the warrant shall be identical in
all material respects to the HSA warrant previously granted to Microsoft.

     If this letter accurately expresses the current discussions between the
parties, and the spirit of our potential future relationship, please indicate
by executing below:


Sincerely,


MICROSOFT CORPORATION
