  Advantest Adopts Stock Option Plan (in the Form of Stock Acquisition Rights)

Tokyo - May 25, 2007 - Advantest Corporation (the "Company") resolved at a
meeting of its Board of Directors today, pursuant to Articles 236, 238 and 239
of the Company Law of Japan to submit to its shareholders, a proposal to
authorize the issuance of stock acquisition rights described hereunder in
connection with stock option grants. The proposal will be made at its 65th
ordinary general meeting of shareholders (the "Shareholders' Meeting") to be
held on June 27, 2007.

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

         The Company will issue stock acquisition rights as stock options on
         especially favorable terms to executive officers and employees of the
         Company and to directors and employees of its domestic and foreign
         subsidiaries for the purpose of enhancing motivation and morale in
         order to improve their performance. In this manner, the Company aims to
         promote a management style conscious of enhancing shareholder value and
         to attract and retain outstanding personnel.

2.       Details of the stock acquisition rights

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

         Executive officers and employees of the Company and directors
         (excluding outside directors) and employees of its domestic and foreign
         subsidiaries.

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

         Not exceeding 700,000 shares of common stock of the Company.

         The number of shares to be issued or delivered upon exercise of each
         stock acquisition right shall be 100 shares, provided, that if the
         subscription price per share has been adjusted in accordance with
         sub-paragraph (5) below, the number of such shares shall be adjusted
         according to the following formula. This adjustment shall be made only
         with respect to stock acquisition rights that have not yet been
         exercised as of the time of adjustment. Any fractional share that
         arises as a result of an adjustment will be rounded down to the nearest
         whole 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 has been 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 the stock
         acquisition rights that have not yet been exercised as of such
         adjustment, then adding the number of shares that have been issued or
         delivered upon exercise of the stock acquisition rights. After the
         adjustment, the total number of shares to be issued or delivered


                                       1


         upon exercise of the stock acquisition rights may exceed 700,000
         shares.

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

         Not exceeding 7,000.

(4)      Payment to be made as consideration for the stock acquisition rights

         No payment is required.

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

         The 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 sub-paragraph (2) above
         (initially, 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 preceding to the month in which any stock acquisition
         rights are allocated (excluding any such day on which there was no
         trade); provided, however, that if such amount is less than the closing
         price of the common stock of the Company on such day of allocation (or,
         if there was no trade on such day of allocation, the closing price on
         the immediately preceding day on which there was any trade), the
         subscription price per share shall be equal to the closing price on
         such day of allocation. The Company may determine the subscription
         price per share to be the same as that for the first stock acquisition
         rights issued based upon this Shareholders' Meeting (if the
         subscription price per share for the first stock acquisition right is
         adjusted by the method described below, such adjusted subscription
         price per share) for any subsequent stock acquisition rights issued.

         If, subsequent to the issuance 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 (subject to
         certain other exceptions including the issuance or delivery of shares
         upon exercise of the stock acquisition rights), the subscription price
         per share shall be adjusted according to the formula set forth below,
         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 merger or split of
         the Company, stock-for-stock exchange or certain other events. The
         Company may determine the subscription price per share for each stock
         acquisition right issued pursuant to the resolution of this
         Shareholders' Meeting after such adjustment to be the same as the
         adjusted subscription price per share.

               consolidation

         Subscription price per  =  Subscription price per    x   ------------------------------

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



                                                                 
                                                             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        ---------------------------------

                                            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".
