This Stock Option Agreement (the “Agreement”) is made and entered into as of the Option Date indicated on the Options and Awards Summary provided with this Agreement by and between Mentor Graphics Corporation, an Oregon corporation (the “Company”), and you. Capitalized terms not otherwise defined in this Agreement shall have the same meanings as set forth in Plan and the Options and Awards Summary. The terms of this Agreement are as follows:

1.	Grant of Option.

The Company hereby grants you an option to purchase shares of the Company’s common stock (the “Option”) under the 1982 Stock Option Plan or the 1986 Stock Plan (the “Plan”). This Option is the most recent option summarized on the Options and Awards Summary provided to you with this Agreement. The number of shares subject to this Option and the price per share are indicated in the Options and Awards Summary. By accepting this Option, you agree to all the terms and conditions of this Agreement, including the Appendix to this Agreement, the Options and Awards Summary and the Plan.

2.	Time of Exercise.

2.1 Subject to Sections 2.2, 2.3, 2.4, 3 and 9.2, this Option may be exercised from time to time to purchase whole shares of the Company’s common stock with respect to which it has become exercisable. This Option shall become exercisable for 25% of the shares on the first anniversary of the Option Date shown on the Option and Awards Summary and for 1/48th of the shares at the end of each one-month period thereafter, so that this Option will be fully exercisable on the fourth anniversary of the Option Date.

2.2 In the event of termination of your employment due to your death, the percent of shares for which this Option is exercisable will be at least 50 percent (i.e., this Option will lapse with respect to no more than 50% of the shares upon termination of your employment due to your death).

2.3 Subject to the limits in Section 3, this Option shall become exercisable in full if a Change in Control (as defined in Section 17.1) occurs and at any time after the earlier of Shareholder Approval (as defined in Section 17.2), if any, or the Change in Control and on or before the first anniversary of the Change in Control, (a) your employment is terminated by the Company without Cause (as defined in Section 17.3), (b) your employment is terminated by you for Good Reason (as defined in Section 17.4), or (c) your employment terminates as a result of your death or Disability (as defined in Section 17.5); provided, however, that this option may also become exercisable in full in connection with a Change in Control as provided in Section 9.2.

2.4 Subject to the limits in 3, this option shall become exercisable in full upon your retirement, which shall mean any termination of your employment after you have reached age 65 and have been employed by the Company for at least 10 years.

2.5 This Option will terminate on the tenth anniversary of the Option Date (the “Termination Date”), unless it is earlier terminated as provided in Section 3 or Section 9.2.

3.	Employment Requirements.

3.1 Notwithstanding the vesting schedule set forth in Section 2.1 above, this Option may not be exercised unless you have been employed by the Company or any of its subsidiaries continuously for at least one year prior to the exercise date except in the event your employment is sooner terminated under circumstances described in Section 2.2 or Section 2.3. Employment before and after the date of this option will be counted. “Employment” for this purpose will include periods of illness or other leaves of absence authorized by the Company or a subsidiary and periods during which you are eligible for disability benefits under a plan maintained by the Company or a subsidiary.

3.2 If your employment with the Company and its subsidiaries terminates, an Option Reference Date will be established. Any portion of this Option that is not exercisable on the Option Reference Date will lapse, subject to the exceptions described in Sections 2.2 and 2.3 above. The Option Reference Date will be fixed as follows:

(a) If you terminate employment by death or Disability, the date one year after the last day of your active employment (subject to Section 4.1(l) below) will be the Option Reference Date.

(b) If you retire on or after age 65, the last day of your active employment (subject to Section 4.1(l) below) will be the Option Reference Date.

(c) If neither (a) nor (b) applies, the Company may fix an Option Reference Date by notice to you. The Option Reference Date cannot be earlier than the notice. This would apply if you quit or were discharged.

(d) If neither (a) nor (b) applies and the Company does not fix a date under (c), the Option Reference Date will be the last day of your active employment (subject to Section 4.1(l) below), disregarding any terminal leave when regular duties are not required.

(e) Notwithstanding the foregoing, if your employment is terminated by the Company without Cause or by you for Good Reason after Shareholder Approval and prior to the occurrence of a Change in Control, the Option Reference Date shall be either (i) the date of the first Change in Control that occurs within one year after Shareholder Approval, or (ii) if no Change in Control occurs during such period, the date determined under (b), (c) or (d), as applicable.

3.3 Any portion of this Option that is exercisable on or before the Option Reference Date may be exercised up to the earlier of the Termination Date or a date fixed as follows:

(a) On death or Disability - one year after the last day of your active employment (subject to Section 4.1(l) below).

(b) On retirement as defined in 2.4 – two years after the last day of your full employment.

(c) If your employment is terminated by the Company without Cause or by you for Good Reason within one year after either Shareholder Approval or a Change in Control - one year after the last day of your active employment (subject to Section 4.1(l) below).

(d) If none of (a), (b) or (c) applies - 30 days after the Option Reference Date.

4.	Nature of Grant; No Advice Regarding Grant.

4.1 In accepting the grant of this Option, you acknowledge that:

(a) the Plan is established voluntarily by the Company, it is discretionary in nature and it may be modified, amended, suspended or terminated by the Company at any time;

(b) the grant of this Option is voluntary and occasional and does not create any contractual or other right to receive future grants of options, or benefits in lieu of options, even if options have been granted repeatedly in the past;

(d) your participation in the Plan shall not create a right to further employment with the Company or any subsidiary of the Company that employs you (the “Employer”) and shall not interfere with the ability of the Employer to terminate your employment relationship at any time;

(e) you are voluntarily participating in the Plan;

(f) this Option and the shares of common stock subject to this Option are an extraordinary item that does not constitute compensation of any kind for services of any kind rendered to the Company, the Employer or any subsidiary of the Company, and which is outside the scope of your employment contract, if any;

(g) the grant of this Option and the shares of common stock subject to this Option are not intended to replace any pension rights or compensation;

(h) this Option and the shares of common stock subject to this Option are not part of any normal or expected compensation or salary for any purposes, including, but not limited to, calculating any severance, resignation, termination, redundancy, dismissal, end of service payments, bonuses, long-service awards, or pension or retirement or welfare benefits or similar payments, and in no event should be considered compensation for, or as relating in any way to, past services for the Company, the Employer or any subsidiary of the Company;

(i) the grant of this Option and your participation in the Plan will not be interpreted to form an employment contract or relationship with the Company or any subsidiary of the Company;

(j) the future value of the underlying shares of common stock is unknown and cannot be predicted with certainty;

(k) in consideration of the grant of this Option, no claim or entitlement to compensation or damages shall arise from forfeiture of this Option resulting from your termination of your employment with the Company or the Employer (for any reason whatsoever and whether or not in breach of local labor laws) and you irrevocably release the Company and the Employer from any such claim that may arise; if, notwithstanding the foregoing, any such claim is found by a court of competent jurisdiction to have arisen, you shall be deemed irrevocably to have waived your entitlement to pursue such claim;

(l) in the event of termination of your employment (whether or not in breach of local labor laws), your right to vest in this Option under the Plan, if any, will terminate effective as of the date that you are no longer actively employed and will not be extended by any notice period mandated under local law (e.g., employment would not include a period of “garden leave” or similar period pursuant to local law); the Company shall have the exclusive discretion to determine when you are no longer employed for purposes of your Option grant; and

(m) except as provided in Section 9.2 below, this Option and the benefits under the Plan, if any, will not automatically transfer to another company in the case of a merger, take-over or transfer of liability.

4.2 The Company is not providing any tax, legal or financial advice, nor is the Company making any recommendations regarding your participation in the Plan or the exercise of this Option or sale of the underlying shares of common stock. You are hereby advised to consult with your own personal tax, legal and financial advisors regarding your participation in the Plan before taking any action related to the Plan.

5.	Nonassignability.

This Option may not be assigned or transferred except on death, by will or operation of law and may be exercised during your lifetime only by you. The terms of this Agreement and the Plan shall be binding upon your executors, administrators, heirs, successors and assigns.

6.	Exercise of Option.

6.1 This Option may be exercised by written notice to the Company stating the number of vested shares you want to buy and the proposed date of exercise, which will be fixed by mutual agreement. If you and the Company do not agree, then the exercise date will be the first working day that is more than 60 days after notice of exercise.

6.2 You must furnish to the Company before exercise such other documents or representations as the Company may require to ensure compliance with applicable laws and regulations. The Company shall not be obligated to issue shares upon exercise of this Option if the Company is advised by its legal counsel that such issuance would violate local, state or federal laws.

6.3 The full purchase price and any applicable Tax-Related Items (as defined in Section 7 below) must be paid in full upon exercise of all or any part of this Option. You may elect to pay the purchase price by cash, check, delivery of Company common stock (unless you are employed outside the U.S.) or consideration received by the Company under a cashless exercise program implemented by the Company in connection with the Plan. Stock delivered in payment of the option price will be valued at fair market value as determined by the Compensation Committee of the Company’s Board of Directors (the “Administrator”). You will not be entitled to any voting or other shareholder rights in respect of any shares subject to the Option until such shares have been issued to you.

7.	Tax Withholding

7.1 Regardless of any action the Company or the Employer takes with respect to any or all income tax, social insurance, payroll tax, payment on account or other tax-related items related to your participation in the Plan and legally applicable to you or deemed by the Company or the Employer to be an appropriate charge to you even if technically due by the Company or the Employer (“Tax-Related Items”), you acknowledge that the ultimate liability for all Tax-Related Items is and remains your responsibility and may exceed the amount actually withheld by the Company or the Employer. You further acknowledge that the Company and/or the Employer (1) make no representations or undertakings regarding the treatment of any Tax-Related Items in connection with any aspect of this Option, including, but not limited to, the grant, vesting, or exercise of this Option, the subsequent sale of shares of common stock acquired upon exercise and the receipt of any dividends; and (2) do not commit to and are under no obligation to structure the terms of the grant or any aspect of this Option to reduce or eliminate your liability for Tax-Related Items or achieve any particular tax result. Further, if you have become subject to tax in more than one jurisdiction between the date of grant and the date of any relevant taxable event, you acknowledge that the Company and/or the Employer (or former employer, as applicable) may be required to withhold or account for Tax-Related Items in more than one jurisdiction.

7.2 Prior to any relevant taxable or tax withholding event, as applicable, you will pay or make adequate arrangements satisfactory to the Company and/or the Employer to satisfy all Tax-Related Items. In this regard, you authorize the Company and/or the Employer, or their respective agents, at their discretion, to satisfy the obligations with regard to all Tax-Related Items by one or a combination of the following:

(a) withholding from your wages or other cash compensation paid by the Company and/or the Employer; or

(b) withholding from proceeds of the sale of shares of common stock acquired upon exercise of this Option, either through a voluntary sale or through a mandatory sale arranged by the Company (on your behalf pursuant to this authorization); or

7.3 To avoid negative accounting treatment, the Company may withhold or account for Tax-Related Items by considering applicable minimum statutory withholding amounts or other applicable withholding rates. If the obligation for Tax-Related Items is satisfied by withholding in shares of common stock, for tax purposes, you are deemed to have been issued the full number of shares of common stock subject to the exercised Options, notwithstanding that a number of the shares of common stock are held back solely for the purpose of paying the Tax-Related Items due as a result of any aspect of your participation in the Plan.

7.4 Finally, you shall pay to the Company or the Employer any amount of Tax-Related Items that the Company or the Employer may be required to withhold or account for as a result of your participation in the Plan that cannot be satisfied by the means previously described. The Company may refuse to issue or deliver the shares or the proceeds of the sale of shares of common stock if you fail to comply with your obligations in connection with the Tax-Related Items.

8.	*Data Privacy.*

You hereby explicitly and unambiguously consent to the collection, use and transfer, in electronic or other form, of your personal data as described in this Agreement and any other Option grant materials by and among, as applicable, the Employer, the Company and its subsidiaries for the exclusive purpose of implementing, administering and managing your participation in the Plan. You understand that the Company and the Employer may hold certain personal information about you, including, but not limited to, your name, home address and telephone number, date of birth, social insurance number or other identification number, salary, nationality, job title, any shares of stock or directorships held in the Company, details of all option grants or any other entitlement to shares of common stock awarded, canceled, exercised, vested, unvested or outstanding in your favor, for the exclusive purpose of implementing, administering and managing the Plan (“Data”). You understand that Data will be transferred to such stock plan service provider as may be selected by the Company, which assists the Company with the implementation, administration and management of the Plan. You understand that the recipients of the Data may be located in the United States or elsewhere, and that the recipients’ country (e.g., the United States) may have different data privacy laws and protections from those of your country. You understand that you may request a list with the names and addresses of any potential recipients of the Data by contacting your local human resources representative. You authorize the Company and any other possible recipients which may assist the Company (presently or in the future) with implementing, administering and managing the Plan to receive, possess, use, retain and transfer the Data, in electronic or other form, for the sole purpose of implementing, administering and managing your participation in the Plan. You understand that Data will be held only as long as is necessary to implement, administer and manage your participation in the Plan. You understand that you may, at any time, view Data, request additional information about the storage and processing of Data, require any necessary amendments to Data or refuse or withdraw the consents herein, in any case without cost, by contacting in writing your local human resources representative. You understand, however, that refusing or withdrawing your consent may affect your ability to participate in the Plan. For more information on the consequences of your refusal to consent or withdrawal of consent, you understand that you may contact your local human resources representative.

9.	Changes in Capital Structure.

Such adjustments shall be made without change in the total value applicable to the unexercised portion of this Option and with a corresponding adjustment in the Option price per share. Fractional shares will be disregarded. Any such adjustment made by the Administrator shall be conclusive.

9.2 If during the term of this option there shall occur a merger, consolidation or plan of exchange involving the Company pursuant to which outstanding shares of common stock of the Company are converted into cash, other securities or other property, or a sale, lease, exchange or other transfer (in one transaction or a series of related transactions) of all, or substantially all, the assets of the Company, then either:

(a) the option shall be converted into an option to purchase stock of the surviving or acquiring corporation in the applicable transaction for a total purchase price equal to the total price applicable to the unexercised portion of this option, and with the amount and type of shares subject thereto and option price per share thereof to be conclusively determined by the Administrator, taking into account the relative values of the companies involved in the applicable transaction and the exchange rate, if any, used in determining shares of the surviving corporation to be held by holders of shares of the Company following the applicable transaction, and disregarding fractional shares; or

(b) the Administrator shall provide a 30-day period prior to such event during which this Option will be exercisable for 100 percent of the shares subject to this Option and after which this Option will terminate.

If you receive US$500,000 or more from the sale of shares, Korean exchange control laws require you to repatriate the proceeds to Korea within 18 months of the sale.

PAKISTAN

Method of Exercise. The following provision supplements Section 6 of the Agreement:

Due to regulatory requirements, you understand that you will be restricted to the cashless sell-all method of exercise. To complete a cashless sell-all exercise, you understand that you need to instruct your broker to (i) sell all of the shares of common stock issued upon exercise; (ii) use the proceeds to pay the purchase price, brokerage fees and any applicable Tax Related Items; and (iii) remit the balance in cash to you.

RUSSIA

U.S. Transaction. You understand that the Option shall be valid and the Agreement shall be concluded and become effective only when your electronic acceptance of the Agreement is received by the Company in the United States. Upon exercise of the Option, the certificates (if any) for any shares of common stock to be issued to you shall be delivered to you through a bank or brokerage account in the United States.

Securities Law Notification. This Appendix, the Agreement, the Plan and all other materials that you may receive regarding participation in the Plan do not constitute advertising or an offering of securities in Russia. The issuance of securities pursuant to the Plan has not and will not be registered in Russia; hence, the securities described in any Plan-related documents may not be used for offering or public circulation in Russia.

Exchange Control Information. In order to perform a cash exercise of the Options, you must remit the funds from a foreign currency account at an authorized bank in Russia. This requirement does not apply if you use a cashless method of exercise, such that there is no remittance of funds out of Russia.

Under current exchange control regulations, within a reasonably short time after sale of the shares of common stock acquired under the Plan, you must repatriate the sale proceeds to Russia. Such sale proceeds must be initially credited to you through a foreign currency account at an authorized bank in Russia. After the sale proceeds are initially received in Russia, they may be further remitted to foreign banks in accordance with Russian exchange control laws. If you exercise your Options through a cashless sell-all method of exercise (whereby you instruct the broker to sell all of the shares issued upon exercise of your Option, use the proceeds to pay the purchase price, brokerage fees and any Tax-Related Items, and remit the balance in cash to you), to the extent that you receive the exercise proceeds through your local payroll, the requirement to credit the proceeds through a Russian authorized bank will not apply to you.

The Company strongly encourages you to contact your personal advisor before remitting your sale proceeds to Russia, as exchange control requirements may change.

SPAIN

No Entitlement for Claims or Compensation. The following provision supplements Section and 4.1 of the Agreement:

By accepting the Option, you consent to participation in the Plan and acknowledge that you have received a copy of the Plan document.

You understand that the Company has unilaterally, gratuitously and in its sole discretion decided to grant Options under the Plan to individuals who may be officers and employees of the Company and any subsidiary of the Company throughout the world. The decision is limited and entered into based upon the express assumption and condition that any Options will not economically or otherwise bind the Company or any subsidiary, including the Employer, on an ongoing basis, other than as expressly set forth in the Agreement. Consequently, you understand that the Options are granted on the assumption and condition that the Options shall not become part of any employment contract (whether with the Company or any subsidiary, including the Employer) and shall not be considered a mandatory benefit, salary for any purpose (including severance compensation) or any other right whatsoever. Furthermore, you understand and freely accept that there is no guarantee that any benefit whatsoever shall arise from the grant of Options, which is gratuitous and discretionary, since the future value of the Options and the underlying shares of common stock is unknown and unpredictable. You also understand that this grant of Options would not be made but for the assumptions and conditions set forth hereinabove; thus, you understand, acknowledge and freely accept that, should any or all of the assumptions be mistaken or any of the conditions not be met for any reason, the Options and any right to the underlying shares of common stock shall be null and void.

Exchange Control Information. You must declare the acquisition of shares of common stock to the Dirección General de Política Comercial e Inversiones Exteriores (“DGPCIE”) of the Ministerio de Economia for statistical purposes. You must also declare the ownership of any shares with the Directorate of Foreign Transactions each January while the shares are owned. In addition, if you wish to import the share certificates into Spain, you must declare the importation of such securities to the DGPCIE.

When receiving foreign currency payments derived from the ownership of shares (i.e., dividends or sale proceeds), you must inform the financial institution receiving the payment of the basis upon which such payment is made. You will need to provide the following information: (i) your name, address, and fiscal identification number; (ii) the name and corporate domicile of the Company; (iii) the amount of the payment and the currency used; (iv) the country of origin; (v) the reasons for the payment; and (vi) further information that may be required.

Tax and National Insurance Contributions Acknowledgment. The following provisions supplement Section 7 of the Agreement:

You agree that if you do not pay or the Employer or the Company does not withhold from you the full amount of Tax-Related Items that you owe due upon the exercise of your Options, or the release or assignment of the Options for consideration, or the receipt of any other benefit in connection with the Options (the “Taxable Event”) within 90 days after the Taxable Event, or such other period specified in Section 222(1)(c) of the U.K. Income Tax (Earnings and Pensions) ▇▇▇ ▇▇▇▇, then the amount that should have been withheld shall constitute a loan owed by you to the Employer, effective 90 days after the Taxable Event. You agree that the loan will bear interest at the HMRC’s official rate and will be immediately due and repayable by you, and the Company and/or the Employer may recover it at any time thereafter by withholding the funds from salary, bonus or any other funds due to you by the Employer, by withholding in shares of common stock issued upon exercise of the Options or from the cash proceeds from the sale of shares of common stock or by demanding cash or a cheque from you. You also authorize the Company to delay the issuance of any shares of common stock to you unless and until the loan is repaid in full.

Notwithstanding the foregoing, if you are an officer or executive director (as within the meaning of Section 13(k) of the U.S. Securities and Exchange Act of 1934, as amended), the terms of the immediately foregoing provision will not apply. In the event that you are an officer or executive director and Tax-Related Items are not collected from or paid by you within 90 days of the Taxable Event, the amount of any uncollected Tax-Related Items may constitute a benefit to you on which additional income tax and national insurance contributions may be payable. You acknowledge that the Company or the Employer may recover any such additional income tax and national insurance contributions at any time thereafter by any of the means referred to in Section 6 of the Agreement.

Joint Election for Transfer of Secondary Class 1 National Insurance Contributions to You. The following provision is added to the Agreement:

You agree to enter into an Election prior to the exercise of Options you receive pursuant to this grant.
