                           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 January 27, 2005 when  consolidated  results for the
quarter ended December 31, 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,

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

Prior forecast (A)    40,000              2,500             2,500        3,300
Revised forecast (B)  40,000              2,500             2,500        4,000
Difference (B-A)           0                  0                 0         +700
Difference (%)             0                  0                 0        +21.2
(For reference)
Prior FY results      38,166               (870)             (911)        (412)

2.   Reasons  for the  revised  forecast:  The SCN  Group's  affiliated  company
     accounted  for by the equity method DeNA Co., Ltd.  (Shibuya  Ward,  Tokyo;
     Representative  Director and CEO Tomoko  Namba) (the SCN Group has 27.7% of
     the voting rights of the company) plans to list on the Tokyo Stock Exchange
     Mothers  Market on February 16, 2005. It has been decided that on that day,
     the offering  price of the company will be 220,000 yen per share.  Based on
     this offering  price,  as a result of the public offering of 14,000 shares,
     it is  expected  that the SCN Group will record a gain on issuance of stock
     by equity investee in which the SCN Group has investment. The SCN Group has
     thus revised its forecast for consolidated results.
