within 30 days after receipt of the Notice or in the manner and at the times set
forth in the Notice.

    17.6  If all of the Shares proposed in the Notice to be transferred to a
given Proposed Transferee are not purchased by Yahoo and/or its assignee(s) as
provided in this Article, then the Holder may sell or otherwise transfer such
Shares to that Proposed Transferee at the Offered Price or at a higher price,
provided that such sale or other transfer is consummated within 60 days after
the date of the Notice and provided further that any such sale or other transfer
is effected in accordance with any applicable securities laws and the Proposed
Transferee agrees in writing that the provisions of this Article shall continue
to apply to the Shares in the hands of such Proposed Transferee.  If the Shares
described in the Notice are not transferred to the Proposed Transferee within
such period, or if the Holder proposes to change the price or other terms to
make them more favorable to the Proposed Transferee, a new Notice shall be given
to Yahoo, and Yahoo and/or its assignees shall again be offered the Right of
First Refusal before any Shares held by the Holder may be sold or otherwise
transferred.

(collectively, "Softbank Party") shall have the option thirty (30) days after
the effective date of such termination, of (i) purchasing all of the shares of

"Independent Auditor"), or (ii) selling all of its shares to Yahoo at fair
market value as determined by an Independent Auditor or (iii) selling the

rights which may be available under the other provisions of this Agreement or
applicable law.
