RESTRICTED STOCK UNIT AWARD AGREEMENT

(US AND NON-US EMPLOYEES)

TERMS AND CONDITIONS

This Restricted Stock Unit Agreement (this “Agreement”) is made and entered into as of the Grant Date as indicated on the Options and Awards Summary provided with this Agreement by and between Mentor Graphics Corporation, an Oregon corporation (“the Company”), and you pursuant to the Mentor Graphics Corporation 1982 Stock Option Plan (the “Plan”). The material terms of this Agreement are as follows:

Pursuant to the Plan, the Company hereby grants you an award of restricted stock units (the “RSUs”) with respect to shares of the Company’s common stock. The grant of RSUs obligates the Company, upon vesting in accordance with this Agreement, to issue to you one share of common stock for each RSU. The number of the RSUs granted to you is indicated on the Options and Awards Summary provided with this Agreement. By accepting this award of the RSUs, you agree to all of the terms and conditions of this Agreement, any appendices to this Agreement and the Plan.

2.1 Except as provided in 2.2, 2.3 or 8.2, the RSUs under this Agreement shall become vested for 25% of the shares on each of the first four anniversaries of the Grant Date shown on the Option and Awards Summary, so that these RSUs will be fully vested on the fourth anniversary of the Grant Date.

2.2 To the extent this grant of RSUs is less than 50% vested at your death or Disability (as defined in 14.5), this grant shall automatically be vested to a total of 50% of the full RSU grant.

2.3 The RSUs shall become 100% vested if a Change in Control (as defined in 14.1) occurs and at any time after the earlier of the Approval Date (as defined in 14.2), 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 14.3), (b) your employment is terminated by you for Good Reason (as defined in 14.4), or (c) your employment terminates as a result of your death or Disability; provided, however, that the RSUs may also become 100% vested in connection with a Change in Control as provided in 8.2.

3.1.1 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;

3.1.2 the grant of the RSUs is voluntary and occasional and does not create any contractual or other right to receive future grants of RSUs, or benefits in lieu of the RSUs, even if the RSUs have been granted repeatedly in the past;

3.1.3 all decisions with respect to future grants of the RSUs, if any, will be at the sole discretion of the Company;

3.1.4 your participation in the Plan shall not create a right to further employment with your employer (the “Employer”) and shall not interfere with the ability of the Employer to terminate your employment relationship at any time;

3.1.5 you are voluntarily participating in the Plan;

3.1.6 the RSUs and the shares of common stock subject to the RSUs 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;

3.1.7 the grant of the RSUs and the shares of common stock subject to the RSUs are not intended to replace any pension rights or compensation;

3.1.8 the RSUs and the shares of common stock subject to the RSUs 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, pension or retirement or welfare benefits or similar payments and in no event should be considered compensation for, or relating in any way to, past services for the Company, the Employer or any subsidiary or affiliate of the Company;

3.1.9 the grant of the RSUs and your participation in the Plan will not be interpreted to form an employment contract or relationship with the Company or any subsidiary or affiliate of the Company;

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

3.1.11 no claim or entitlement to compensation or damages shall arise from forfeiture of the RSUs resulting from the termination of your employment by the Company or the Employer (for any reason whatsoever and whether or not in breach of local labor laws) and in consideration of the grant of the RSUs to which you are otherwise not entitled, you irrevocably agree never to institute any claim against the Company or the Employer, waive your ability, if any, to bring any such claim, and release the Company and the Employer from any such claim; if, notwithstanding the foregoing, any such claim is allowed by a court of competent jurisdiction, then, by participating in the Plan, you shall be deemed irrevocably to have agreed not to pursue such claim and agree to execute any and all documents necessary to request dismissal or withdrawal of such claims;

3.1.12 in the event of termination of your employment (whether or not in breach of local labor laws), your right to vest in the RSUs 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 mandate 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 RSU grant;

3.1.13 in the event of termination of your employment for any reason, the RSUs that are not vested at that time, and that do not become vested under 2.2 or 2.3 as a result of the circumstances of your termination, shall be forfeited and you shall have no right to receive the underlying shares of common stock; and

3.1.14 except as provided in section 8.2 below, the RSUs 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.

3.2 No Advice Regarding Grant. 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 your acquisition 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.

The RSUs may not be assigned or transferred except on death, by will or operation of law.

As soon as practicable on or after the date on which the RSUs become vested, the Company will issue to you the number of shares of common stock underlying the RSUs that vested, and will deliver such shares to a brokerage account established by you in accordance with instructions from the Company or in such other manner as may be determined by the Company.

6.1 If you are a U.S. taxpayer, you acknowledge that on each date that shares underlying the RSUs are issued to you (the “Payment Date”), the fair market value of the shares of common stock will be treated as ordinary compensation income for U.S. federal and state income and FICA tax purposes, and that the Company will be required to withhold taxes on these income amounts pursuant to section 6.3 below.

6.2 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 the RSUs, including, but not limited to, the grant, vesting, or settlement of the RSUs, the subsequent sale of shares of common stock acquired pursuant to such issuance and the receipt of any dividends and/or dividend equivalents; and (2) do not commit to and are under not obligation to structure the terms of the grant or any aspect of the RSUs 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.

6.3 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:

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

6.3.2 withholding from proceeds of the sale of shares of common stock acquired upon vesting/settlement of the RSUs, either through a voluntary sale or through a mandatory sale arranged by the Company on your behalf pursuant to this authorization; or

6.3.3 withholding in shares of common stock to be issued upon vesting/settlement of the RSUs.

6.4 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 vested RSUs, 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.

6.5 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.

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 RSU 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 the RSUs 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 E*TRADE Financial, or such other stock plan service provider as may be selected by the Company in the future, which is assisting 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, E*TRADE Financial 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.

8.1 If, prior to the full vesting of all the RSUs awarded under this Agreement, the outstanding shares of common stock of the Company are increased or decreased or changed into or exchanged for a different number or kind of shares or other securities of the Company by reason of any recapitalization, reclassification, stock split, combination of shares, or dividend payable in shares, appropriate adjustment shall be made by the Compensation Committee of the Company’s Board of Directors (the “Administrator”) in the number and kind of shares subject to the unvested RSUs under this Agreement so that your proportionate interest before and after the occurrence of the event is maintained. Fractional shares will be disregarded. Any such adjustment made by the Administrator shall be conclusive.

8.2 If, prior to the full vesting of all the RSUs awarded under this Agreement, 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:

8.2.1 the unvested RSUs shall be converted into restricted stock units of the surviving or acquiring corporation in the applicable transaction, with the amount and type of shares to be issued under such converted restricted stock units to be 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; or

8.2.2 the unvested RSUs shall become 100% vested and all underlying shares shall be issued simultaneously with the closing of the applicable transaction such that you will participate as a shareholder in receiving proceeds from such transaction with respect to those shares.

Subject to the limits in section 4 above, this Agreement will be binding upon and benefit the parties, their successors and assigns.

10.1 The grant of RSUs and the provisions of this Agreement are governed by and subject to, the laws of the state of Oregon, without regard to the conflict of law provisions, as provided in the Plan.

10.2 For purposes of litigating any dispute that arises directly or indirectly from the relationship of the parties evidenced by this grant or this Agreement, the parties hereby submit to and consent to the exclusive jurisdiction of the state of Oregon and agree that such litigation shall be conducted only in the courts of Clackamas County, Oregon, or the federal courts for the United States for the District Court of Oregon, and no other courts, where this grant is made and/or to be performed.
