                          FOR THE CURRENT FISCAL YEAR

  Sony Communication Network Corporation (hereinafter, the "SCN Group"), a
subsidiary the performance of which is linked to a tracking stock issued by Sony
Corporation, announced today the following revisions to the forecast for
consolidated results for the fiscal year ending March 31, 2005.  The previous
forecast was announced on July 28, 2004 when consolidated results for the
quarter ended June 30, 2004 were released.

1.       The SCN Group announces the following revisions to the forecast for the
year ending March 31, 2005 (the period from April 1, 2004 to March 31, 2005).

                                                               (millions of yen)
                       Sales      Ordinary Income   Operating Income  Net Income

Prior forecast (A)     40,000           1,500              1,500           700

Revised forecast (B)   40,000           1,500              1,500         3,700

Difference (B-A)            0               0                  0        +3,000

Difference (%)              0               0                  0        +428.6

(For reference)
Prior FY results       38,166           (870)              (911)         (412)

2.       Reasons for the revised forecast:
The SCN Group's consolidated subsidiary So-net M3 Inc. (Shinagawa Ward, Tokyo;
Representative Director and CEO Itaru Tanimura) plans to list on the Tokyo Stock
Exchange Mothers Market on September 16, 2004.  It has been decided to price the
offering at 850,000 yen per share.  In conjunction with the public offering, the
SCN Group expects to sell 3,260 shares of So-net M3 Inc. which it holds.  Based
on the above offering price, the SCN Group has thus revised its forecast for
consolidated results.  However, the offering of any shares through an over
allotment with securities companies is not reflected in this revised forecast.
