This excerpt taken from the ATVI 10-Q filed Aug 4, 2005.
Share Option Agreements; etc. All Options granted pursuant to this Article 4 (a) shall be authorized by the Committee and (b) shall be evidenced in writing by share option agreements (Share Option Agreements) in such form and containing such terms and conditions as the Committee shall determine that are not inconsistent with the provisions of the Plan, and, with respect to any Share Option Agreement granting Options that are intended to qualify as ISOs, are not inconsistent with Section 422 of the Code. Granting of an Option pursuant to the Plan shall impose no obligation on the recipient to exercise such Option. To the extent that any Option does not qualify as an ISO (whether because of its provisions, the time or manner of its exercise or otherwise) such Option or the portion thereof which does not so qualify shall constitute a separate NQO.
