STOCK OPTION AGREEMENT



TERMS AND CONDITIONS



MAGMA DESIGN AUTOMATION, INC.



2001 Stock Incentive Plan



THIS STOCK OPTION AGREEMENT TERMS AND CONDITIONS (the Agreement),
together with the Notice of Stock Option Grant (the Notice of Grant) to which this Agreement is attached, constitute the Stock Option Agreement referred to in the Magma Design Automation, Inc. 2001 Stock Incentive Plan (the
Plan) with respect to the option granted to you pursuant to the Notice of Grant (the Option). This Option is intended to be a Nonstatutory Stock Option, as provided in the Notice of Grant.



1. Exercise



The Option evidenced by this Agreement becomes exercisable [vesting
schedule], as summarized in the Notice of Grant. Your rights to exercise the Option accrue only for the time period you render Service to the Company following your vesting commencement date. Your vesting commencement date is [insert].



2. Term The Option expires on the date shown in the Notice of
Grant, but in no event later than the fifth anniversary of the Date of Grant set forth in the Notice of Grant. The Option may expire earlier in connection with the termination of your Service, as described below.



3. Regular Termination If your Service with the Company or a Subsidiary
terminates for any reason excluding death, Total and Permanent Disability or Cause (as defined below), and whether or not in breach of local labor law, this Option will expire on the date three months after your Termination Date. Your
Termination Date will be the date you are no longer actively providing Service to the Company (not extended by any notice period mandated under local law).



4.Death or Disability If your Service with the Company or a Subsidiary terminates as a result of your Total and Permanent
Disability or death, this Option will expire on the date six months after your Termination Date.



5. CauseIf your Service with the Company or a Subsidiary terminates for Cause, this Option will expire on the date seven days following your Termination Date. For purposes of this section,
Cause shall mean (i) continued failure to perform substantially your duties, which standard of duties shall be referenced to the standards set by the Company at the date of this Agreement (other than as a result of sickness,
accident or similar cause beyond your reasonable control) after receipt of a written warning and your being given thirty (30) days to cure the failure; (ii) willful misconduct or gross negligence, which is demonstrably injurious to the
Company or any of its Subsidiaries, including without limitation willful or grossly negligent failure to perform your material duties as an officer or employee of the Company or any of its Subsidiaries or a material breach of this Agreement, your
employment agreement (if any) or your Proprietary Information and Inventions Agreement with the Company; (iii) conviction of or plea of nolo contendere to a felony; or (iv) commission of an act of fraud against, or the misappropriation of
property belonging to, the Company or any affiliated company, employee, customer or supplier of the Company.



6. Leaves of Absence For purposes of this Option, your Service does not terminate when you go on a military leave of absence, a sick leave of absence or another bona fide leave of absence, if the leave
of absence was approved by the Company in writing and if continued crediting of Service is required by the terms of the leave or by applicable law. Your Service will terminate when the approved leave of absence ends unless you immediately return to
active employment. Except as provided by applicable law, or unless expressly provided in writing pursuant to a Company-approved leave of absence, the period of the approved leave of absence will not be credited as Service to the Company for the
purposes of determining when your Option vests. In accordance with the preceding sentence, the dates on which the Option would otherwise vest will be postponed by the number of days of the approved leave of absence.



7. Restrictions on Exercise The Company will not permit you to exercise this
Option if the issuance of Shares at that time would violate any law or regulation. The exercise of this Option and the issuance and immediate sale of the



---

Shares upon such exercise is subject to all applicable laws, rules, and regulations, and to such approvals by any
governmental agencies or national securities exchanges as may be required. No Shares will be issued to you under the Plan unless and until there has been compliance with such applicable laws.



8. Notice of Exercise When you wish to exercise this Option you must notify the
Company by completing the Notice of Stock Option Exercise in the form attached to this Agreement (or such other form approved by the Company) (the Notice of Exercise) and filing it with the Treasury Department of the Company. Because you
will be required to exercise your Option via a cashless exercise through a securities broker approved by the Company, the Notice of Exercise form must be filed in advance and approved by the Company prior to placing the order with the broker. The
exercise of your Option will be effective when the Notice of Exercise and payment of the Exercise Price is received and approved by the Company. This Notice of Exercise form may be superseded by a Company-sponsored web-based trading program that
includes security measures sufficient to ensure your identification, such that your entry of a cashless exercise constitutes your request and authorization to exercise the Option. If someone else wants to exercise this Option after your death, that
person must prove to the Companys satisfaction that he or she is entitled to do so.



9. Form of Payment Due to local regulatory issues in your country, payment may be made only by means of by delivering a Committee-approved form of irrevocable direction to a securities broker approved by
the Company to issue to you and immediately sell all the Shares subject to the Option and to deliver to the Company from the sale proceeds an amount sufficient to pay the aggregate Exercise Price and any withholding taxes (including social insurance
contributions and payment on account obligations). The balance of the sale proceeds will be delivered to you. You will not receive any Shares. The Company reserves the right to eliminate the requirement to use a cashless exercise method of exercise
and, in its sole discretion, to permit other methods of exercise and forms of payment should local regulatory requirements change.



10. Withholding Taxes and Stock Withholding



Regardless of any action the Company or your employer (the Employer) takes with respect to any or all income
tax, social insurance, payroll tax, payment on account or other tax-related withholding (Tax-Related Items), you acknowledge that the ultimate liability for all Tax-Related Items legally due by you is and remains your responsibility and
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 Option grant, including the grant, vesting or exercise of the Option and the
immediate sale of Shares acquired pursuant to such exercise; and (2) do not commit to structure the terms of the grant or any aspect of the Option to reduce or eliminate your liability for Tax-Related Items.



In exercising your Options through the cashless exercise method, you will pay
or make adequate arrangements satisfactory to the Company and/or the Employer to satisfy all withholding and payment on account obligations for Tax-Related Items of the Company and/or the Employer. In this regard, you authorize the Company and/or
the Employer to withhold all applicable Tax-Related Items legally payable by you from your wages or other cash compensation paid to you by the Company and/or the Employer or from proceeds of the sale of Shares. Finally, you will pay to the Company
or the Employer any amount of Tax-Related Items that the Company or the Employer may be required to withhold as a result of your participation in the Plan or your exercise of Options that cannot be satisfied by the means previously described. The
Company may refuse to honor the exercise of the Option if you fail to comply with your obligations in connection with the Tax-Related Items as described in this section.



11. Transfer of Option



Prior to your death, only you can exercise this Option. You cannot sell, transfer, assign, pledge or otherwise alienate this
Option. For instance, you may not sell this Option or use it as security for a loan. If you attempt to do any of these things, this Option will immediately become invalid. You may in any event dispose of this Option in your will. Regardless of any
marital property settlement agreement, the Company is not obligated to honor a notice of exercise from your former spouse, nor is the Company obligated to recognize your former spouses interest in your Option in any other way.



---

12. Retention Rights



Neither your Option nor this Agreement give you the right to be retained by
the Company or a Subsidiary in any capacity. The Company and its Subsidiaries reserve the right to terminate your Service at any time, with or without Cause.



13. Nature of Grant



In accepting the grant, you acknowledge that:



| | 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, unless
otherwise provided in the Plan and this Agreement;
| | -- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 2) | the grant of the 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;
| | -- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 3) | all decisions with respect to future option grants, if any, will be at the sole discretion of the Company;

scope of your employment contract, if any;
| | -- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 6) | the Option is not part of normal or expected compensation or salary for any purposes, including, but not limited to, calculating any severance, resignation, termination, redundancy,
end of service payments, bonuses, long-service awards, pension or retirement benefits or similar payments and in no event should be considered as compensation for, or relating in any way to, past services for the Company or the Employer;
| | -- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 7) | in the event that you are not an employee of the Company, the Option grant will not be interpreted to form an employment contract or relationship with the Company; and furthermore,

| | -- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 8) | the future value of the underlying Shares is unknown and cannot be predicted with certainty;
| | -- | --------------------------------------------------------------------------------------------



| | 9) | if the underlying Shares do not increase in value, the Option will have no value;
| | -- | ---------------------------------------------------------------------------------



| | 10) | in consideration of the grant of the Option, no claim or entitlement to compensation or damages shall arise from termination of the Option or diminution in value of the Option
resulting from 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 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, then, by signing this Agreement, you shall be deemed irrevocably to have waived your entitlement to pursue such claim; and
| | --- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 11) | in the event of termination of your employment (whether or not in breach of local labor laws), your right to receive additional Options and to vest in the Option under the Plan, if
any, will terminate effective as of your Termination Date (e.g., active employment would not include a period of garden leave or similar period pursuant to local law); the Committee shall have the exclusive discretion to determine
when you are no longer actively employed for purposes of your Option grant.
