Except where the context otherwise requires, the term "Company" shall include the parent and all subsidiaries of the Company. 2. Type of Options and Administration. ---------------------------------- (a) TYPES OF OPTIONS. Options granted pursuant to the Plan shall be authorized by action of the Board of Directors of the Company (or a Committee designated by the Board of Directors) and may be either incentive stock options ("Incentive Stock Options") meeting the requirements of Section 422A of the Internal Revenue Code of 1986, as amended (the "Code") or non-statutory options which are not intended to meet the requirements of Section 422A.
