Pursuant to the International Rectifier Corporation 2000 Incentive Plan (Amended and Restated as of November 22, 2004) (the "Plan"), the Company has granted a nonqualified stock option to purchase authorized but unissued or treasury shares of Common Stock, $1.00 par value, of the Company as described below on the terms and conditions attached hereto and in the Plan:

(1)

Subject to adjustment under Section 5.2 of the Plan.

(2)

Subject to accelerated vesting and/or early termination as provided in Section 2.5 or 5.2 of the Plan and Section 4 of the attached Terms and Conditions, if the Optionee ceases to serve as a Non-Employee Director of the Company or in certain other circumstances set forth in the Plan or this Agreement. See the Terms and Conditions and the Plan for other exceptions and additional details regarding the Option.
