Tokyo, May 25, 2007- DAIICHI SANKYO COMPANY, LIMITED has announced that its Board of Directors today reached a decision to propose a resolution, at the Second Ordinary General Meeting of Stockholders slated for June 28, 2007,
to remunerate directors with stock options pursuant to Article 361 of the Corporate Code (Act No. 86 of 2005).

Description of Proposed Resolution
With respect to fees to Directors, Auditors and Corporate Officers, the Company is pursuing its review into remuneration systems that are linked to the improvement of its corporate value and rather than employing the retirement benefit system, the Company shall grant share remuneration-type stock options,which use stock acquisition rights based on an exercise price of one yen per share, to Directors and Corporate Officers
The Company therefore requests approval for setting a framework of remunerations, etc. concerning stock acquisition rights (amount obtained by multiplying the fair value of per one allocated stock acquisition right by the total number of stock acquisition rights), which will be allocated to Directors of the Company as share remuneration-type stock options as follows, with a ceiling limit of 140 million yen per annum for each business year.
These stock options are to be distinct from directors' cash compensation (maximum 450 million yen annually), and all directors except external directors shall be eligible to received them.

Details of stock acquisition rights
1. Number of shares to be issued upon exercise of stock acquisition rights
The number of shares per one stock acquisition right shall be 100 in ordinary shares of the Company. If the Company effects a stock split of its shares (including allotment of ordinary shares to shareholders without consideration) or effects a stock consolidation, the number of shares subject to one stock acquisition right shall be adjusted to the extent reasonable.

2. Amount of assets paid upon exercise of stock acquisition rights
The assets paid upon exercise of the stock acquisition rights shall be the amount calculated by multiplying the per-share amount, which stands at 1yen, by the number of shares that are granted per one stock acquisition right.

3. Exercise period for the stock acquisition rights
Any person granted stock acquisition rights may exercise his or her rights from the following day of the day he or she retired from office of director to the last day of the business year within 10 years from his or her retirement.

4. Conditions for exercising the stock acquisition rights
Each stock acquisition right cannot be partially exercised.

5. Restriction on transfer of the stock acquisition rights
Acquisition of stock acquisition rights through transfer shall be subject to the approval of the Board of Directors.

6. Other details of the stock acquisition rights
The details of the above-mentioned from 1 to 5 and other matters shall be decided by the Board of Directors of the Company.
