Agenda Item No. 1:  Approval of the proposed appropriation of retained earnings
                    for the 63rd fiscal year

         The details of the appropriation of retained earnings for this fiscal
year are as described on page 27 of the attached document "Report for the 63rd
Fiscal Year."

         The basic policy of the Company is to continue to provide stable
dividends at a level consistent with its operating results, based on the belief
that shareholder value is premised on the realization of long-term and
sustainable growth in corporate value.

         Based on the above policy, the Company proposes to pay a yearend
dividend of JPY 25 per share for the fiscal year (which, together with the
interim dividend of JPY 25 per share already paid, amounts to a fiscal year
total of JPY 50 per share, representing an increase of JPY 10 per share over the
previous fiscal year).



Agenda Item No. 2:  Partial amendment of the Articles of Incorporation

     Commercial Code and the Law Concerning Introduction of Electronic Public
     Notice" (Law No. 87 of 2004) effective as of February 1, 2005, in addition

Agenda Item No. 5:  Issuance of stock acquisition rights as stock options


         Pursuant to Articles 280-20 and 280-21 of the Commercial Code, we
request that you approve the issuance of stock acquisition rights on especially
favorable terms as described below.



1.   Reason for the issuance of stock acquisition rights on especially favorable
     terms

     The stock acquisition rights will be issued as stock options to directors,
     corporate auditors, executive officers and employees of the Company and its
     domestic and overseas subsidiaries as an incentive to improve business
     performance and to attract and retain talented individuals while raising
     the awareness of shareholder value.

2.   Details of stock acquisition rights

(1)  Persons to whom stock acquisition rights will be allocated

     Directors, corporate auditors, executive officers and employees of the
     Company and its domestic and overseas subsidiaries, and overseas
     subsidiaries of the Company. The overseas subsidiaries will then allocate
     the same rights as the stock acquisition rights pursuant to applicable
     local laws to directors, corporate auditors and employees of other overseas
     subsidiaries.

(2)  Class and total number of shares to be issued or delivered upon exercise of
     the stock acquisition rights

     Not exceeding 800,000 shares of common stock of the Company.



                                       5


     The number of shares to be issued or delivered upon exercise of each stock
     acquisition right shall be 100 shares, provided, however, that when the
     subscription price per share is adjusted in accordance with (5) below, the
     number of such shares shall be adjusted according to the following formula.
     This adjustment is made only with respect to any such stock acquisition
     rights that have not yet been exercised as of the time of adjustment. Any
     fraction of a share that arises as a result of an adjustment will be
     rounded down to the nearest number of shares.

       Number of shares to be issued or           Total subscription price
       delivered upon exercise of each    =   --------------------------------
           stock acquisition right              Subscription price per share

     When the number of shares to be issued or delivered upon exercise of each
     stock acquisition right is adjusted, the total number of shares to be
     issued or delivered upon exercise of the stock acquisition rights shall be
     adjusted to the number obtained by multiplying (i) the number of shares to
     be issued or delivered upon exercise of each stock acquisition right after
     adjustment by (ii) the number of stock acquisition rights that have not yet
     been exercised as of the time of such adjustment, then adding the number of
     shares that have been issued or delivered upon exercise of stock
     acquisition rights. After the adjustment, the total number of shares to be
     issued or delivered upon exercise of the stock acquisition rights may
     exceed - 800,000 shares.

(3)  Total number of stock acquisition rights to be issued

     Not exceeding 8,000.

(4)  Issue price of the stock acquisition rights

     No consideration shall be paid.

(5)  Total subscription price to be paid upon exercise of each stock acquisition
     right

     The total subscription price to be paid upon exercise of each stock
     acquisition right shall be determined by multiplying (i) the subscription
     price per share as determined in the following paragraph, by (ii) the
     number of shares to be issued or delivered upon exercise of each stock
     acquisition right as specified in (2) above (100 shares).

     The subscription price per share shall be 1.05 times the average closing
     price, rounded up to the nearest yen, of the common stock of the Company in
     regular trading on the Tokyo Stock Exchange on each day of the month
     (excluding any such day on which there was no trade) preceding the first
     occasion on which any stock acquisition rights approved by this
     Shareholders' Meeting are issued; provided, however, that if such amount is
     less than the closing price of the common stock of the Company on such day
     of issue (or, if there was no trade on such day of issue, the closing price
     on the immediately preceding day on which there was any trade), the
     subscription price per share shall equal the closing price on such day.

     If, subsequent to the issue of the stock acquisition rights, the Company
     splits or consolidates its common stock, or issues new shares or disposes
     of its treasury shares below market price (other than to issue or deliver
     shares upon exercise of stock acquisition rights, with certain other
     exceptions), the subscription price per share shall be adjusted according
     to the following formula, rounded up to the nearest yen. Furthermore, the
     subscription price per share may, to the extent necessary and reasonable,
     be adjusted in a way deemed appropriate by the Company, in the case of a
     capital reduction, merger or split of the Company or certain other events.

     (a)  Formula for adjustment in the case of share split or consolidation

       Subscription price   Subscription price                   1
           per share      =     per share      x  ------------------------------
        after adjustment    before adjustment     Ratio of split / consolidation

     (b)  Formula for adjustment in the case of issue of new shares or
          disposition of treasury stock below market price



                                       6








                                                         Number of new        Subscription
                                        Outstanding       shares to be   x   price per share
     Subscription     Subscription       number of    +      issued           to be issued
       price per   =    price per    x    shares         -----------------------------------
     share after      share before                             Market price per share

                                          Outstanding number of       Number of new shares
                                                 shares           +       to be issued



     In the above formula, "outstanding number of shares" shall mean the total
     number of outstanding shares of the Company after deduction of shares held
     by the Company as treasury stock. In the case of disposition of treasury
     stock, "number of new shares to be issued" in the above formula shall be
     read as "number of treasury shares to be disposed of."

(6)  Exercise period of the stock acquisition rights

     Between April 1, 2006 and March 31, 2010 (4 years).

(7)  Conditions for exercise of stock acquisition rights

     (a)  A person to whom stock acquisition rights are allocated (a "rights
          holder"), other than overseas subsidiaries of the Company, must be a
          director, corporate auditor, executive officer or employee of the
          Company or its domestic or overseas subsidiary at the time of
          exercise, except where there are reasons deemed reasonable.

     (b)  The stock acquisition rights may not be inherited.

     (c)  No stock acquisition right may be exercised in part.

     (d)  Other terms and conditions will be determined at a meeting of the
          Board of Directors subsequent to the Shareholders' Meeting.

(8)  Cancellation of stock acquisition rights

     (a)  The Company may cancel, for no consideration, any stock acquisition
          right in the event that the general meeting of the shareholders
          resolves to approve (i) any merger agreement pursuant to which the
          Company shall cease to exist, or (ii) any share exchange agreement or
          share transfer pursuant to which the Company shall become a
          wholly-owned subsidiary of another company.

     (b)  The Company may cancel, for no consideration, all or part of the stock
          acquisition rights of a rights holder to the extent that such stock
          acquisition rights are not exercisable due to the rights holder's
          failure to satisfy any of the conditions for exercise of stock
          acquisition rights.

(9)  Restriction on the transfer of stock acquisition rights

     Any transfer of stock acquisition rights shall require the approval of the
     Board of Directors, except where the transferee is the Company.

(10) Other details of the stock acquisition rights will be determined in a
     meeting of the Board of Directors subsequent to the Shareholders' Meeting.
