Subsidiary Tracking Stock
Sony Communication Network Corporation
Consolidated Financial Results for the Three-months ended June 30, 2005

   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 its consolidated results for the three-months ended
June 30, 2005 (the period from April 1, 2005 to June 30, 2005).

These results are based on the generally accepted accounting standards of Japan.

- Increased sales compared to year earlier period; increased net income

  During the quarter under review, sales increased 4.0% compared with the year
  earlier period, to 10,016 million yen. Operating income of 10 million yen,
  compared with 721 million yen in the year earlier period, and ordinary income 
  of 110 million yen, compared with 771 million yen in the year earlier period, 
  were recorded. Due to the recording of gain on sale of investment in affiliate
  and subsidiary stock, under extraordinary income, of 17,795 million yen, net 
  income of 10,303 million yen, compared with 393 million yen in the year 
  earlier period, was recorded.

- Subscribers at 2.51 million; big increase in broadband subscribers,
  especially for FTTH

  At the end of the quarter under review, the number of So-net subscribers 
  totaled 2.51 million, an increase of 9.1% over the end of the year earlier 
  period.  Within this, the number of broadband subscribers increased by 21.1% 
  to 690,000.  New broadband subscribers, in particular for FTTH, increased 2.5 
  times compared to the year earlier period, to about 50,000.

  Sales of Connection Services (see note 1) decreased 6.6% to 6,835 million 
  yen, compared to 7,318 million yen in the year earlier period, due to the 
  effects of free promotional campaigns. Also, due to customer acquisition 
  measures, acquisition costs increased, but it is expected that this will make 
  a contribution to profitability from the second half of the year ending March 
  31, 2006.

- Portal Services advances smoothly

  Sales in Portal Services (see note 2) increased by 37.6%, from 2,312 million 
  yen in the year earlier period, to 3,181 million yen. This was a result
  CS-broadcasting of Korean dramas, web contents, and increased sales of 
  products such as goods and related DVDs.

  Note 1: The sales category known as "Internet provider services" through the
  fiscal year ended March 31, 2005 is now known as "Connection Services." There
  has not been any change in type of services in this sales category.
  Note 2: The closely related sales categories known as "Internet-related
  services" and "Merchandise sales" through the fiscal year ended March 31, 2005

Summary of Consolidated Operations (April 1, 2005 to June 30, 2005)
----------------------------------

Regarding sales, during the quarter under review, sales increased 4.0% to 
10,016 million yen, compared with 9,630 million yen in the year earlier period.

In the category of Connection Services, in conjunction with active customer
acquisition efforts, particularly for FTTH, the number of So-net broadband
subscribers increased by 120,000 compared to the end of the year earlier period,
to 690,000. However, with the impact of free promotional campaigns, sales in
this category declined.

On the other hand, in the category of Portal Services, sales increased as a
result of sales in CS-broadcasting and web contents, as well as greatly
increased sales of consolidated subsidiaries.

Furthermore, the total number of So-net subscribers increased by 210,000 from
the end of the year earlier period, to 2,510,000. This was mainly a result of
increases in the number of broadband subscribers and the number of content
users.

Regarding operating income, during the quarter under review, operating income
declined 98.6% compared with the year earlier period, from 721 million yen to 10
million yen. Because active efforts were made in the area of customer
acquisitions compared to the year earlier period, there was a great increase in
costs such as for television commercials and customer acquisition commissions
which are recorded under "selling, general and administrative expenses".

Regarding ordinary income, during the quarter under review, ordinary income
decreased 85.8%, from 771 million yen to 110 million yen. Factors offsetting the
impact of the decline in operating income included an improvement in net
non-operating income compared with the year earlier period, in particular, 75
million yen of equity in net income of affiliated companies was recorded,
stemming from the recording of a profit by DeNA Co., Ltd.

Regarding net income before income taxes, during the quarter under review, 
net income before income taxes increased by 2,223.2%, from 771 million yen to 
17,905 million yen.

This was a result of partial sales of the SCN Group's shares in So-net M3 
Inc., a consolidated subsidiary, and DeNA Co., Ltd., a company accounted for by 
the equity method. As a result of these sales, a gain on sale of investment in
affiliate and subsidiary stock of 17,795 million yen was recorded as an
extraordinary gain.

As a result, the total income tax charges, including both income tax current 
and income tax deferred were 7,552 million yen. Furthermore, minority interest
income of 50 million yen was recorded, compared with 10 million yen in the year
earlier period.

Regarding net income, there was an increase of 2,521.1% compared with the year
earlier period, from 393 million yen to 10,303 million yen .

Operating revenue

Connection Services
-------------------
In this category, as a result of always-on broadband connections becoming the
mainstream, the SCN Group has aggressively worked to promote customer
acquisitions for FTTH connection plans. By utilizing television commercials, the
SCN Group is working to raise awareness of these services, and the SCN Group has
also worked towards customer acquisition activities at high-volume retailers and
cooperating retailers.

As a result, new customers for broadband connections were 2.5 times the year
earlier period, at 50,000 members. At the end of the quarter under review, there
were 690,000 broadband subscribers, an increase of 21.3% over the year earlier
period. Also, they accounted for 27% of the total number of So-net subscribers.

On the other hand, there were effects from free promotional campaigns aimed at
attracting new broadband subscribers, and there was also a decline in the number
of narrowband subscribers. As a result, sales of Connection Services for the
quarter ended June 30, 2005 were 6,835 million yen, a decrease of 6.6% compared
with the year earlier period. Such sales accounted for 68.2% of total sales.

Portal Services
---------------
In this category, there were increases in sales of web contents and of
advertising sales. Also, sales related to Korean dramas on the CS-broadcasted
So-net channel 749 smoothly progressed.

In the area of e-commerce, sales were strong for products connected with
contents related to sports such as pro-baseball and J-League, anime, theaters,
and fashion.

With respect to subsidiary companies, sales increased at So-net M3 Inc. and
Skygate, Co., Ltd.

As a result, sales in this category during the quarter under review increased
37.6% compared with the year earlier period, to 3,181 million yen. Sales in this
category accounted for 31.8% of total sales.



Results of Consolidated Subsidiaries and of Affiliated Companies Accounted for
by the Equity Method

The SCN Group includes the following five consolidated subsidiaries: So-net
Sports.com Corp., So-net M3 Inc., So-net M3 U.S.A. Corp., Medi C&C Co. Ltd. (see
note 3), and Skygate, Co., Ltd. The SCN Group includes the following two
affiliated companies accounted for by the equity method: Label Gate Co., Ltd.
and DeNA Co., Ltd.

During the quarter under review, the SCN Group sold a portion of its shares in
So-net M3 Inc. and DeNA Co., Ltd. As a result, its share of So-net M3 Inc.
declined from 74.8% to 60.8%, and its share of DeNA Co., Ltd. declined from
24.7% to 20.0%.

With regards to So-net M3 Inc., during the quarter under review, the
medically-related site "m3.com" topped 100,000 in physician members. Also,
So-net M3 Inc. has taken actions to grow, including cooperation with the
American company Medsite (see note 4), acquire the Korean company Medi C&C Co.
Ltd., and, by expanding available information of diseases for its general
service Q&A website for asking questions of 100,000 subscriber doctors,
"AskDoctors B" (a beta-stage site).

At Skygate, Co., Ltd., turnover increased thanks to an emphasis on 
international airplane tickets.

Also, during the quarter under review, equity in net income of affiliated
companies of 75 million yen was recorded, compared with 5 million yen in the
year earlier period. This was largely due to strong growth at DeNA Co., Ltd. and
its subsidiary Mbok Inc., which offers auction services for mobile phones.
Furthermore, DeNA began charging a 315 yen (tax included) per month fee from
July 1, 2005, with the aim of making its auction services more secure and
user-friendly.

In conjunction with the recent expansion of the music download market, Label
Gate Co., Ltd. also saw increases in available songs and the number of paid
downloads.

Note 3: Medi C&C Co. Ltd operates "Medigate," a website for doctors which has
gained 86% of Korean doctors as members.

Note 4: Medsite has over 450,000 members, over 50% of American doctors. It
offers online educational programs for doctors and online marketing services for
medically related businesses.

Cash Flow

Cash and cash equivalents were 27,663 million yen at the end of the quarter
ended June 30, 2005, an increase of 25,236 million yen from the end of the year
earlier period, and an increase of 17,023 million yen from March 31, 2005.
During the quarter under review, the SCN Group used 876 million yen of cash in
operating activities, generated 17,896 million yen of cash in investing
activities, and saw no change in cash in financing activities.

Cash flows from operating activities

During the quarter ended June 30, 2005, regarding cash flows from operating
activities, the SCN Group used 876 million yen, compared with the quarter ended
June 30, 2004 when the SCN Group generated 326 million yen. During the quarter
under review, while net income before income taxes of 17,905 million yen was
recorded, an overwhelming portion of that was a gain on sale of investment in
affiliate and subsidiary stock of 17,795 million yen. The main reason for the
decline in cash flows from operating activities compared with the year earlier
period was payment of 827 million yen in income taxes, compared with payment of
197 million yen in the year earlier period. Also, during the quarter under
review, included in net income before income taxes were non-cash depreciation
expense of 203 million yen and amortization of goodwill of 71 million yen.

Cash flows from investing activities

During the quarter ended June 30, 2005, regarding cash flows from investing
activities, the SCN Group generated 17,896 million yen, compared with the
quarter ended June 30, 2004 when the SCN Group used 81 million yen. The main
factor in the period under review was the cash proceeds from sale of investment
in affiliate and subsidiary stock of 18,499 million yen as a result of sales of
stock in consolidated subsidiary So-net M3 Inc. and affiliated company DeNA Co.,
Ltd.

Cash flows from financing activities

During the quarter ended June 30, 2005, regarding cash flows from financing
activities, similar to the year earlier period, the SCN Group did not carry out
any financing or repayment activities.
