EXHIBIT 10-F 	 		 EMPLOYMENT AGREEMENT The parties to this Agreement are R. Douglas Norby ("Employee") and Mentor Graphics Corporation, an Oregon corporation (the "Company"). 	 The Company desires to secure the services of Employee to serve in an executive capacity, and Employee is willing to accept such employment upon the terms and conditions set forth in this Agreement. Therefore, the parties agree as follows: 1. Employment. The Company employs Employee to render services to the Company as Senior Vice President and Chief Financial Officer and to perform such duties as he shall reasonably be directed to perform by the Chief Executive Officer (CEO) of the Company. Employee accepts employment by the Company and agrees to render the services described in this Agreement. 2. Duties and Responsibilities.

He will perform his duties and responsibilities in an ethical and professional manner in accordance with the policies and objectives established by the Board of Directors of the Company and all applicable laws and regulations. He will not perform services for any other business or entity during the term of this Agreement and will devote full time to his employment by the Company and will work as many hours as the business of the Company may reasonably demand. 		Notwithstanding the above, Employee may (i) engage in personal investment activities in charitable or community service, (ii) serve as a director of LSI Logic Corporation, Epitope, Inc. and Pharmetrix Corporation, and (iii) complete certain job related obligations to Pharmetrix Corporation, provided that after the date Employee begins full time regular employment with the Company, those engagements will not materially interfere with Employee's duties under this Agreement. With the consent of the CEO, Employee may serve on the boards of other corporations. 3. Term. The term of this Agreement shall be two years, commencing on Employee's hire date and expiring at the close of business on the second anniversary of that date, unless this Agreement is sooner terminated. 	 4. Compensation. 		 (a) The Company will pay Employee a base annual salary of $235,000, payable in equal bimonthly installments, as compensation for all services to be rendered by Employee under this Agreement, subject to annual review by the Compensation Committee of the Board of Directors of the Company. 	 (b) The Company will pay Employee an annual incentive bonus with a target payout of $100,000 to be paid on performance during the previous fiscal year. Any incentive bonus payout for 1993 would be prorated from Employee's hire date.

The Company will grant to Employee stock options to purchase 100,000 shares of its common stock at an exercise price of $10.375, or the price approved at the July 1993 meeting of the Compensation Committee of the Board of Directors, whichever is lower. The Compensation Committee of the Company's Board of Directors, in its sole discretion will determine whether Employee will receive incentive or nonqualified stock options. Vesting will begin on Employee's hire date. The options will vest with continued employment in equal 20 percent increments on the first five anniversaries of the date of grant and will be ten year options (subject to earlier termination in the event of termination of employment).
