Sony Communication Network Corporation (hereinafter, the "SCN Group"), a
subsidiary of which the performance is linked to tracking stock issued by Sony
Corporation, announced today the following revisions to the forecast for its
consolidated results for the fiscal year ending March 31, 2006. The previous
forecast was announced on June 20, 2005 when SCN announced revision its
consolidated results for the year ended March 31, 2006.

1.The SCN Group announces the following revisions to the forecast for the year
ending March 31, 2006 (the period from April 1, 2005 to March 31, 2006).

                                                               (millions of yen)
                      Sales    Operating Income   Ordinary Income   Net Income
Prior forecast (A)    43,500              1,300             1,500       10,800
Revised forecast (B)  43,500                500               700       10,200
Difference (B-A)           0               (800)             (800)        (600)
Difference (%)             0              (61.5)            (53.3)        (5.6)
(For reference)

Prior FY results      39,302              2,624             2,540        4,107

2.Reasons for the revised forecast:
Consolidated financial results forecasts for the fiscal year ending March 31,
2006, have been revised, with specific reasons for each, as follows.

(1) Operating income
Since last fiscal year, SCN has made great effort to increase the number of new
FTTH broadband subscribers. This effort has been very successful and we plan to
continue it during the second half. As a result, we anticipate that costs to
acquire new subscribers will increase. In addition, due to promotional campaigns
and other factors, telecommunications line usage fees and other costs will be
incurred before revenues are registered.

(2) Ordinary income
The main reason for the downward revision in ordinary income is the same as that
for operating income, as stated above.

(3) Net income
Lower forecasts for operating and ordinary income, as explained above, are the
main reason for the downward revision in our net income forecast.

(4) So-net subscriber numbers
Prior forecasts of the total number of subscribers as of March 31, 2006, were
2.8 million (of which 800,000 are broadband subscribers). However, as of August
31, 2005, the total number of subscribers reached 2.78 million, of which 720,000
were broadband subscribers. As a result, we forecast that the total number of
So-net subscribers as of March 31, 2006, will reach 2.95 million, of which
830,000 will be broadband subscribers.
