These agreements generally provide for the payment, upon the termination of the employee's employment by the Company without cause or by the employee for "good reason" (as defined in the severance agreement) within in 6 some cases one year, and in other cases two years, following a change of control of the Company, of an amount equal to either 1.5 or two times the sum of the employee's annual salary and target bonus, and also provide for accelerated vesting of all options and either eighteen-month or two-year continuation of various employee benefits including life, disability and health insurance benefits and relocation and outplacement benefits. Payments to the employee are capped as necessary to prevent any portion of the payments from being subject to the excise tax on "parachute payments" but only if the effect would be to increase the employee's after-tax net benefit. REPORT OF THE BOARD OF DIRECTORS' COMPENSATION COMMITTEE The philosophy of the Company's executive compensation plan is to: (a) attract highly talented executives; (b) motivate executives to high levels of performance; (c) retain needed executive resources; and (d) recognize the differing impact that various executives have on the achievement of corporate goals. To achieve these objectives, the Company pays executive officers on a total compensation approach that includes base salary, "at risk" compensation that is dependent on corporate performance, and stock options. The Compensation Committee of the Board of Directors, which is comprised of non-employee directors, reviews and approves the compensation to be paid to executive officers. Compensation of executive officers consists of the following components: BASE SALARY: Salaries for executive officers are reviewed on an annual basis. In reviewing executive salaries, data from a third party survey is considered. In using the third party survey, the Company compares itself to other high-technology companies with annual revenues of $200 million to $500 million, and generally establishes salaries in the third quartile (50th to 75th percentile) for the group. This group of comparable companies differs from the companies in the Media General index used for the performance graph that follows this report, which consists of companies in the computer software and services businesses without regard to annual revenue. The salary survey group may include those companies in the Media General index with annual revenues of $200 million to $500 million, while it does not include companies in the Media General index with revenues outside of the $200 million to $500 million range. Nonetheless, the Company believes that the salary survey group is an appropriate peer group for compensation purposes. VARIABLE COMPENSATION: The Compensation Committee annually establishes a Variable Incentive Plan to provide for the payment of a portion of compensation to executive officers and other employees based on corporate performance. Under the Variable Incentive Plan, each year the Compensation Committee approves a target variable compensation amount for each executive officer to be paid based on achievement of the target net income from the annual business plan approved by the Board of Directors (Annual Plan). For this purpose, the Company's reported net income may be adjusted by the Compensation Committee to exclude unusual items such as acquisition-related expenses, one-time charges and reversals. The potential variable compensation increases or decreases based on the achievement of higher or lower net income. The potential variable compensation for executive officers other than the Chief Executive Officer is then subject to further adjustment up or down based on individual performance. For 1998, target variable compensation for executive officers ranged from 30 percent to 70 percent of base salary, with 100 percent of the target payable upon attainment of the target net income from the Annual Plan and no variable compensation payable unless 76% of the target net income from the Annual Plan was achieved. In 1998 the Company's net income, after adjustments approved by the Compensation Committee, was 108% of the target net income and variable compensation was paid out to executive officers under the Variable Incentive Plan. 7 In addition, certain executives with sales responsibility receive variable pay based on sales performance of their divisions. STOCK OPTIONS: The Company believes that stock options granted to key employees, including executive officers, provide such persons with significant compensation based on overall Company performance as reflected in the stock price, create a valuable retention device through standard four-year vesting schedules and help align employees' and shareholders' interests. Stock options are typically granted at the time of hire to key new employees and annually to a broad group of existing key employees including executive officers. Most executive officers received stock option grants as part of the 1998 annual option grant program for key employees. The 1998 annual option program for all employees involved a total pool of approximately 1,600,000 shares. During 1998, individual award levels were determined primarily by a matrix that allocated the available shares based on position within the Company, with some discretionary adjustments based on subjective performance factors. Third party survey data was considered in establishing the upper levels of the matrix with the Company seeking to grant options in the middle range of comparable companies. DEDUCTIBILITY OF COMPENSATION: Section 162(m) of the Internal Revenue Code limits to $1,000,000 per person the amount that the Company may deduct for compensation paid to any of its most highly compensated officers in any year. The levels of salary and bonus generally paid by the Company do not exceed this limit. Upon the exercise of nonqualified stock options the excess of the current market price over the option price (option spread) is treated as compensation and, therefore, it may be possible for option exercises by an officer in any year to cause the officer's total compensation to exceed $1,000,000. Under IRS regulations, option spread compensation from options that meet certain requirements will not be subject to the $1,000,000 cap on deductibility, and it is the Company's current policy generally to grant options that meet those requirements. COMPENSATION OF CHIEF EXECUTIVE OFFICER: Dr. Rhines' base salary was increased from $425,000 to $450,000 in April 1998. This salary level is in the third quartile of CEO salaries among comparable companies from the third party survey used by the Company. Dr. Rhines received a Variable Incentive Plan bonus of $394,494 for 1998. Dr. Rhines was granted an option to purchase 180,000 shares of Company stock in March 1998, which was in the middle range of CEO option grants for comparable companies.

As a result of a 1998 internal restructuring by Media General Financial Services of its industry group classification system, Media General Financial Services no longer supports that industry group. Media General Financial Services now classifies the company in a similar industry group entitled "Computer Software & Services." 9 APPROVAL OF AMENDMENT TO 1982 PLAN (PROPOSAL NO. 2) Mentor Graphics' 1982 Stock Option Plan (1982 Plan) was adopted by the Board of Directors and the shareholders in 1982. An aggregate of 18,670,000 shares are currently reserved for issuance under the plan. AMENDMENT On March 4, 1999, only 689,823 shares of Common Stock were available for future grants under the 1982 Plan. An additional 893,540 shares of Common Stock were available for future grants under the Company's 1986 Stock Plan, but Nasdaq and tax rules limit the Company's ability to grant options to officers of the Company under that plan. The Board of Directors believes that additional shares must be reserved for use under the 1982 Plan to enable the Company to attract and retain officers and other key employees through the granting of options under the plan. Accordingly, in February 1999, the Board of Directors approved an amendment to the 1982 Plan, subject to shareholder approval, to reserve an additional 3,000,000 shares for issuance under the plan. In addition, shareholder approval of this proposal will constitute reapproval of the per-employee limit on grants of options under the 1982 Plan of 500,000 shares annually. This reapproval is required every five years for continued compliance with regulations under Section 162(m) of the Internal Revenue Code of 1986. See "Tax Consequences." DESCRIPTION OF THE 1982 PLAN A copy of the 1982 Plan, as proposed to be amended, is attached to this Proxy Statement as Exhibit A. The essential features of the 1982 Plan, as currently in effect, are outlined below. GENERAL The 1982 Plan provides for grant of incentive stock options (ISOs) within the meaning of Section 422 of the Internal Revenue Code, and nonqualified stock options (NQSOs). See "Tax Consequences" below for information concerning the tax treatment of ISOs and NQSOs. The plan permits stock appreciation rights (SARs) to be granted in tandem with or independent of ISOs and NQSOs. Cash bonus rights may also be granted under the 1982 plan. ADMINISTRATION The 1982 Plan is administered by the Compensation Committee. The Compensation Committee determines the officers and key employees to whom options and SARs will be granted, the exercise prices, the number of shares covered by each grant and all other terms and conditions of the grants. GRANT OF OPTIONS The option price of ISOs cannot be less than the fair market value of the Common Stock on the date the option is granted. The plan provides that the option price of NQSOs cannot be less than 50% of the fair market value. On March 4, 1999, the closing price of Common Stock on the Nasdaq National Market was $13.875 per share. No employee may be granted options or stock appreciation rights under the plan for more than an aggregate of 500,000 shares in any calendar year. In addition, no employee may be granted ISOs under the 1982 Plan such that the fair market value of stock (determined on the grant date) subject to ISOs that first become exercisable in any year exceeds $100,000. Options may be granted under the 1982 Plan in exchange for outstanding options. EXERCISE OF OPTIONS At the date of exercise, the optionee may pay the full option price in cash or in shares of Company stock previously acquired by the optionee valued at fair market value. The use of previously acquired 10 shares to pay the option price enables the optionee to avoid the need to fund the entire purchase with cash. Upon exercise of an option, the number of shares subject to the option and the number of shares available under the plan for future grants are reduced by the number of shares with respect to which the option is exercised. Options may be exercised only while the holder is in the employ of the Company or a subsidiary, within 30 days after either the date of termination of employment or another date set by the Company, or within one year after the death or disability of the holder. During the optionee's lifetime, an option is exercisable only by the optionee. Options are not transferable except upon the death of the optionee or pursuant to a qualified domestic relations order as defined under the Internal Revenue Code or Title I of the Employee Retirement Income Security Act. Terminated or expired options become available for future grants. Options are generally not exercisable until one year from the date of grant or from the commencement of employment. Options typically become exercisable over a period of time, generally set at four years, in accordance with the terms of option agreements entered into at the time of grant. STOCK APPRECIATION RIGHTS The Committee determines the terms and conditions of SARs granted under the 1982 Plan, including the schedule under which SARs vest and become exercisable. SARs granted with an option may be exercised only to the extent the related option could be exercised. SARs entitle the holder, upon exercise, to receive without payment to the Company (except for applicable withholding taxes) an amount equal to the excess of the fair market value of the Company's Common Stock on the exercise date over the SAR exercise price. Payment may be made in cash, shares or any combination thereof. No SARs have been granted under the 1982 Plan. CHANGE IN CONTROL PROVISION The 1982 Plan authorizes the Compensation Committee to accelerate the vesting of all outstanding options and SARs upon a change in control of the Company. The plan allows the Compensation Committee to authorize the issuance and exercise of "limited" SARs in connection with options granted or previously granted under the plan. Limited rights are payable in connection with, and exercisable only during the 60 days immediately following, a change in control of the Company. A "change in control" is defined to include the following events, unless otherwise determined by the Compensation Committee prior to the occurrence of the event: the acquisition by any person of 20% or more of the Company's Common Stock, the nomination (and subsequent election) of a majority of the Company's directors by persons other than the incumbent directors, or the approval by the Company's shareholders of a merger, consolidation, share exchange, sale of substantially all of the Company's assets or plan of liquidation. Limited SARs are payable only in cash and are exercisable only if the immediate resale of an optionee's shares would subject the optionee to liability under Section 16(b) of the Securities Exchange Act of 1934. CASH BONUS RIGHTS Under the 1982 Plan, cash bonus rights may be granted in connection with NQSOs. Bonus rights entitle the optionee to a cash bonus if and when the related NQSO is exercised and may be used for the payment of income taxes resulting from the exercise. The amount of the bonus will generally be equal to the difference between the aggregate exercise price of the NQSO and the fair market value of the shares subject to the NQSO on the exercise date, multiplied by the bonus percentage, determined by the Compensation Committee and not to exceed 100 percent. The Compensation Committee may set a maximum dollar limit on the amount of cash to be paid under any bonus right. No bonus rights have been granted under the 1982 Plan. 11 DURATION Options and SARs may be granted for varying periods not to exceed approximately ten years from the date of grant. The 1982 Plan will be in effect until options and SARs have been granted with respect to all shares available for the plan. The Board of Directors may terminate the plan at any time, but termination will not affect options or SARs already outstanding. TAX CONSEQUENCES ISOs granted under the 1982 Plan are intended to qualify as "incentive stock options" for federal income tax purposes. Under federal income tax law currently in effect, the optionee will recognize no income upon grant or exercise of the ISO. Federal income tax upon any gain resulting from exercise of an ISO is deferred until the optioned shares are sold by the optionee. The gain resulting from the exercise of any ISO is included in the alternative minimum taxable income of the optionee and may, under certain conditions, be taxed under the alternative minimum tax. If an employee exercises an ISO and does not dispose of any of the optioned shares within two years following the date of grant and within one year follow the date of exercise, then any gain upon subsequent disposition will be treated as long-term capital gain for federal income tax purposes. If an employee disposes of shares acquired upon exercise of an ISO before expiration of either the one-year or the two-year holding period, any amount realized will be taxable for federal income tax purposes as ordinary income in the year of such disqualifying disposition to the extent that the lesser of the fair market value of the shares on the exercise date or the fair market value of the shares on the date of disposition exceeds the exercise price. The Company will not be allowed any deduction for federal income tax purposes either at the time of the grant or exercise of an ISO. Upon any disqualifying disposition by an employee, the Company will generally be entitled to a deduction to the extent the employee realizes ordinary income. NQSOs granted under the 1982 Plan are intended to be "nonqualified stock options" for federal income tax purposes. Under federal income tax law presently in effect, no income is realized by the grantee of an NQSO until the option is exercised. At the time of exercise of an NQSO, the optionee will realize ordinary income, and the Company will generally be entitled to a deduction, in the amount by which the market value of the shares subject to the option at the time of exercise exceeds the exercise price (Option Spread Amount). The Company's deduction is conditioned upon withholding on the Option Spread Amount. Upon sale of shares acquired upon exercise of an NQSO, the excess of the amount realized from the sale over the market value of the shares on the date of exercise will constitute long-term capital gain if the shares have been held for the required holding period. An optionee who receives a cash bonus right under the 1982 Plan will generally recognize ordinary income equal to the amount of the cash bonus at the time of receipt and the Company will be entitled to a deduction in the same amount. On exercise of a SAR, the amount realized by the holder will, for federal tax purposes, be taxed as ordinary income, and the Company will be allowed to take a deduction for such amount. The SAR holder is subject to withholding on such income. Under current accounting principles, the Company will be required to account for the increase in value of an outstanding SAR as compensation expense (and may take a credit to compensation expense for a decrease in such value to the extent a prior expense has been recorded) over the period the SAR holder provides services to the Company. Current financial accounting principles do not require similar ongoing charges to earnings in connection with options. Section 162(m) of the Internal Revenue Code limits to $1,000,000 per person the amount that the Company may deduct for compensation paid to any of its most highly compensated officers in any year. Under IRS regulations, compensation received through the exercise of an option will not be subject to the $1,000,000 limit if the option and the plan meet certain requirements. One such requirement is shareholder approval at least once every five years of a per-employee limit on the number of shares as to which 12 options may be granted. Approval of this Proposal No. 2 will constitute reapproval of the per-employee limit under the 1982 Plan previously approved by the shareholders. Other requirements are that the option be granted by a committee of at least two outside directors and that the exercise price of the option be not less than fair market value of the Common Stock on the date of grant. Accordingly, the Company believes that if this proposal is approved by shareholders, compensation received on exercise of options granted under the 1982 Plan in compliance with all of the above requirements will continue to be exempt from the $1,000,000 deduction limit. VOTE REQUIRED FOR APPROVAL The affirmative vote of the holders of at least a majority of the Common Stock present at the Annual Meeting in person or by proxy and entitled to vote on the matter is required for adoption of Proposal No. 2. Abstentions will therefore have the same effect as "no" votes in determining whether the proposal is approved. Broker non-votes are counted for purposes of determining whether a quorum exists at the Annual Meeting but are not counted and have no effect on the results of the vote on Proposal No. 2. All valid proxies will be voted FOR Proposal No. 2 unless a contrary choice is indicated. THE BOARD HAS UNANIMOUSLY APPROVED PROPOSAL NO. 2. MANAGEMENT AND THE BOARD RECOMMEND ITS APPROVAL BY THE SHAREHOLDERS. 13 INDEPENDENT AUDITORS The Board of Directors has selected KPMG Peat Marwick LLP as the Company's independent auditors for 1999. KPMG Peat Marwick LLP has examined the financial statements of the Company and its subsidiaries each year since the inception of the Company in 1981. Representatives of KPMG Peat Marwick LLP will be present at the Annual Meeting, will have the opportunity to make a statement if they so desire and will be available to respond to appropriate questions. SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE Section 16(a) of the Securities Exchange Act of 1934 requires the Company's executive officers, directors and persons who own more than ten percent of the Common Stock to file reports of ownership and changes in ownership with the Securities and Exchange Commission ("SEC"). Executive officers, directors and beneficial owners of more than ten percent of the Common Stock are required by SEC regulation to furnish the Company with copies of all Section 16(a) forms they file. Based solely on a review of the copies of such forms received by the Company and on written representations from certain reporting persons that they have complied with the relevant filing requirements, the Company believes that all Section 16(a) filing requirements applicable to its executive officers and directors were complied with in 1998. DISCRETIONARY AUTHORITY While the Notice of Annual Meeting of Shareholders provides for transaction of such other business as may properly come before the meeting, the Board of Directors has no knowledge of any matters to be presented at the meeting other than those referred to in this Proxy Statement. However, the enclosed proxy gives discretionary authority in the event any other matters should be presented. SHAREHOLDER PROPOSALS The Company's bylaws require shareholders to give the Company advance notice of any proposal or director nomination to be submitted at any meeting of shareholders. The bylaws prescribe the information to be contained in any such notice. For any shareholder proposal or nomination to be considered at the 2000 Annual Meeting of Shareholders, the shareholder's notice must be received at the Company's principal executive office no later than February 11, 2000. In addition, SEC rules require that any shareholder proposal to be considered for inclusion in the Company's proxy statement for the 2000 Annual Meeting of Shareholders must be received at the Company's principal executive office no later than December 4, 1999. By Order of the Board of Directors [SIGNATURE] Dean Freed VICE PRESIDENT, GENERAL COUNSEL AND SECRETARY April 2, 1999 14 EXHIBIT A MENTOR GRAPHICS CORPORATION 1982 STOCK OPTION PLAN Mentor Graphics recognizes that its continuing success depends upon the initiative, ability and significant contributions of officers and key employees. Mentor Graphics believes that by affording such employees the opportunity to purchase shares in Mentor Graphics it will enhance its ability to attract and retain such employees and will provide an incentive for them to exert their best efforts on its behalf. The Plan is as follows: 1. SHARES SUBJECT TO OPTION. 1.1 Options granted under this Plan shall be for authorized but unissued or reacquired common stock of Mentor Graphics. 1.2 Options may be granted under paragraph 4 of the Plan and stock appreciation rights may be granted under paragraph 8.2 of the Plan for a total of not more than 21,670,000 [18,670,000]* shares of common stock, subject to adjustment under paragraph 9. Shares subject to options and to stock appreciation rights granted under paragraph 8.2 that are terminated or expire without being exercised, other than options that are surrendered on exercise of a stock appreciation right granted under paragraph 8.1, shall be added to the shares remaining for future options and stock appreciation rights. 1.3 No employee may be granted options or stock appreciation rights under the Plan for more than an aggregate of 500,000 shares of Common Stock in any calendar year. 2. EFFECTIVE DATE; DURATION. This Plan shall be effective January 1, 1982 and shall continue until all shares available for issuance under the Plan have been issued, unless sooner terminated by the Board of Directors of Mentor Graphics (Board of Directors). Expiration or termination of the Plan shall not affect outstanding options, bonus rights or stock appreciation rights. 3. ADMINISTRATION. 3.1 The Plan shall be administered by a compensation committee appointed by the Board of Directors (Committee). The Committee may delegate any of its administrative duties to one or more agents and may retain advisors to assist it. 3.2 The Committee shall have general responsibility to interpret and administer the Plan. Any decision by the Committee shall be final and bind all parties. Notwithstanding the foregoing, the Committee's exclusive power to make final and binding interpretations of the Plan shall immediately terminate upon the occurrence of a Change in Control (as defined in paragraph 7.2). The Committee shall keep adequate records of options, bonus rights and stock appreciation rights granted under the Plan and shall be responsible for communication with optionees. 3.3 No Committee member shall participate in the decision of any question relating exclusively to an option, bonus right or stock appreciation right granted to the member. - ------------------------ *Matter in BOLDFACE is new; matter [BRACKETED AND IN ITALICS] has been deleted. A-1 4. GRANT OF OPTIONS. 4.1 Options granted under the Plan may be either incentive stock options within the meaning of Section 422 of the Internal Revenue Code of 1986, as amended (the Code), or options other than incentive stock options (nonqualified stock options). No incentive stock options may be granted under the Plan on or after the tenth anniversary of the last action by the Board of Directors approving an increase in the number of shares available for issuance under the Plan, which action was subsequently approved within 12 months by the shareholders. 4.2 Options may be granted to any officer or key employee of Mentor Graphics and any subsidiary of Mentor Graphics and may be granted in substitution for outstanding options of another corporation by reason of merger, consolidation, acquisition of property or stock, or other reorganization between such other corporation and Mentor Graphics or any subsidiary of Mentor Graphics. Additional options may be granted to existing optionees and may be granted in exchange for outstanding options. 4.3 The Committee shall designate persons to receive grants, and as to each option shall specify the number of shares, the option price and term, the time or times at which the option may be exercised, whether the option is an incentive stock option or a nonqualified stock option and all other terms and conditions of the option. 4.4 No employee may be granted incentive stock options under the Plan such that the aggregate fair market value, on the date of grant, of the shares with regard to which incentive stock options are exercisable for the first time by that employee during any calendar year under the Plan and under any other stock option plan of Mentor Graphics or any parent or subsidiary of Mentor Graphics exceeds $100,000. Fair market value shall be determined under subparagraph 5.1(c) as of the date of each grant. 5. OPTION TERMS. 5.1 The option price shall be fixed by the Committee as follows: (a) Subject to (b) the option price for an incentive stock option shall be not less than the fair market value of the shares on the date of grant. The option price for a nonqualified stock option shall be not less than 50% of the fair market value of the shares on the date of grant. (b) If the optionee at the time of grant owns stock possessing more than 10 percent of the combined voting power of all classes of stock of Mentor Graphics, the option price for an incentive stock option shall be not less than 110 percent of the fair market value of the shares on the date of grant. Stock owned by the optionee shall include for this purpose, and for purposes of paragraph 5.2, stock attributed to the optionee pursuant to applicable provisions of the Code. (c) "Fair market value" means an amount determined by, or in an manner approved by, the Committee. The Committee may appoint and rely on one or more qualified independent appraisers to value the stock or use such other evaluation as it considers appropriate. 5.2 The Committee shall fix a time limit of not over 10 years after the date of grant for exercise of an incentive stock option. The Committee shall fix a time limit of not over 10 years plus seven days after the date of grant for exercise of a nonqualified stock option. For a more than 10 percent shareholder the maximum limit for exercise of an incentive stock option shall be 5 years. The Committee may make the option exercisable in full immediately or in graduated amounts over the option term. 5.3 The option shall be evidenced by a stock option agreement executed by Mentor Graphics and the optionee in a form prescribed by the Committee. 5.4 The option may not be assigned or transferred except on death, by will or operation of law, or pursuant to a qualified domestic relations order as defined under the Code or Title I of the Employee A-2 Retirement Income Security Act. The option may be exercised only by the optionee or by a successor or representative after death. 5.5 Unless otherwise determined by the Committee, if an officer of Mentor Graphics subject to Section 16 of the Securities Exchange Act of 1934 (1934 Act) exercises an option within six months of the grant of the option, the shares acquired upon exercise of the option may not be sold until six months after the date of grant of the option. 6. BONUS RIGHTS. 6.1 The Committee may grant bonus rights in connection with nonqualified stock options granted under the Plan. Bonus rights may be granted with the related option or at a later time. A bonus right may not be assigned or transferred except on death, by will or operation of law, or pursuant to a qualified domestic relations order as defined under the Code or Title I of the Employee Retirement Income Security Act. Bonus rights will be subject to such rules, terms, and conditions as the Committee may prescribe. 6.2 A bonus right will entitle an optionee to a cash bonus in connection with the exercise in whole or in part of the related option. Subject to paragraph 6.3, the amount of the bonus shall be determined by multiplying the applicable bonus percentage by the amount by which the fair market value, on the exercise date, of the shares received on exercise of the related option exceeds the option price. The cash bonus will be payable within 30 days following the date as of which its amount is determined. For the purpose of this paragraph, fair market value shall be determined according to subparagraph 5.1(c). The bonus percentage applicable to a bonus right shall be determined by the Committee, but shall in no event exceed 100 percent. 6.3 The Committee may set a maximum dollar limit on the amount of cash to be paid under any bonus right. 7. ACCELERATION UPON CHANGE IN CONTROL. 7.1 The Committee may grant acceleration rights to holders of options or stock appreciation rights which will provide that the options or stock appreciation rights will become exercisable in full for the remainder of their terms upon the occurrence of a Change in Control. Acceleration rights may be granted with an option or stock appreciation right or at a later time by amendment of outstanding options or stock appreciation rights. 7.2 "Change in Control" means the occurrence of any of the following events, unless prior to the occurrence of the event, the Committee determines that the specific event shall not be considered a Change in Control: (a) the shareholders of Mentor Graphics shall approve: (i) any consolidation, merger or plan of share exchange involving Mentor Graphics (Merger) in which Mentor Graphics is not the continuing or surviving corporation or pursuant to which shares of common stock would be converted into cash, securities or other property, other than a Merger involving Mentor Graphics in which the holders of Mentor Graphics' common stock immediately prior to the Merger have the same proportionate ownership of common stock of the surviving corporation immediately after the Merger; (ii) any sale, lease, exchange or other transfer (in one transaction or a series of related transactions) of all, or substantially all, the assets of Mentor Graphics; or (iii) the adoption of any plan or proposal for the liquidation or dissolution of Mentor Graphics; A-3 (b) at any time during a period of two consecutive years, individuals who at the beginning of such period constituted the Board of Directors (Incumbent Directors) shall cease for any reason to constitute at least a majority thereof, unless each new director elected during such two-year period was nominated or elected by two-thirds of the Incumbent Directors then in office and voting (new directors nominated or elected by two-thirds of the Incumbent Directors shall also be deemed to be Incumbent Directors); or (c) any person (as such term is used in Section 13(d) of the 1934 Act) shall, as a result of a tender or exchange offer, open market purchases, privately negotiated purchases or otherwise, have become the beneficial owner (within the meaning of Rule 13d-3 under the 1934 Act), directly or indirectly, of securities of Mentor Graphics ordinarily having the right to vote in the election of directors (Voting Securities) representing twenty percent (20%) or more of the combined voting power of the then outstanding Voting Securities. 8. STOCK APPRECIATION RIGHTS. 8.1 (a) The Committee, in its sole discretion, may grant both "general" and "limited" stock appreciation rights with all or any part of an incentive stock option or a nonqualified stock option granted under the Plan. Stock appreciation rights may be granted with the related option or at any later time during the term of the option. (b) A general stock appreciation right granted with all or any part of an option shall be exercisable only at the time or times established by the Committee and only to the extent that the related option could be exercised. A limited stock appreciation right shall be exercisable only during the 60 calendar days immediately following a Change in Control and only if the immediate resale of shares acquired upon exercise of the related option would subject the optionee to liability under Section 16(b) of the 1934 Act; provided, however, that a limited stock appreciation right may not be exercised within six months of its date of grant. Upon exercise of a stock appreciation right, the option or portion thereof to which the stock appreciation right relates must be surrendered. The shares subject to an option or portion thereof that is surrendered upon exercise of a stock appreciation right shall not be available for future option or stock appreciation right grants under the Plan. (c) Each stock appreciation right granted with all or any part of an option shall entitle the holder to receive from Mentor Graphics an amount equal to the excess of the fair market value at the time of exercise of one share of Mentor Graphics common stock over the option price per share under the related option, multiplied by the number of shares covered by the related option or portion of the related option. (d) The terms of a limited stock appreciation right granted with a nonqualified stock option may provide, if so determined by the Committee, that the fair market value of the common stock for purposes of subparagraph 8.1(c) shall be equal to the higher of: (i) the highest reported sales price of the common stock during the 60-day period ending on the date the limited stock appreciation right is exercised; (ii) the highest per share price paid for shares of common stock purchased in any tender or exchange offer during the 60 calendar days preceding the exercise of the limited stock appreciation right; (iii) the fixed or formula price to be received by holders of shares of common stock in or as a result of any transaction described in subparagraph 7.2(a) if such price is determinable on the date of exercise, provided that any securities or other property that are part of the fixed or formula price shall be valued at the highest valuation placed on the securities or property in any communication to the shareholders of Mentor Graphics by any party to the transaction; and A-4 (iv) the highest price per share shown on a Schedule 13D, or any amendment thereto, filed by the holder or holders of the specified percentage of common stock whose acquisition gives rise to the exercisability of the limited stock appreciation right. 8.2 (a) The Committee may grant general stock appreciation rights without related options under the Plan to any officer or key employee of Mentor Graphics and any subsidiary of Mentor Graphics. Such stock appreciation rights may be granted in substitution for outstanding stock appreciation rights of another corporation by reason of merger, consolidation, acquisition of property or stock, or other reorganization between such other corporation and Mentor Graphics or any subsidiary of Mentor Graphics. Additional stock appreciation rights may be granted to existing holders of stock appreciation rights and may be granted in exchange for outstanding stock appreciation rights. (b) The Committee shall designate persons to receive grants of stock appreciation rights, and as to each stock appreciation right shall specify the number of shares, the stock appreciation right price, the term, the time or times at which the stock appreciation right may be exercised and all other terms and conditions of the stock appreciation right. The stock appreciation right price shall not be less than 50% of the fair market value of the shares on the date of grant. (c) Each stock appreciation right granted without a related option shall entitle the holder to receive from Mentor Graphics an amount equal to the excess of the fair market value at the time of exercise of one share of Mentor Graphics common stock over the stock appreciation right price, multiplied by the number of shares covered by the stock appreciation right or portion thereof that is exercised. The shares subject to a stock appreciation right or portion thereof that is exercised shall not be available for future option or stock appreciation right grants under the Plan. 8.3 (a) Payment upon exercise of a general stock appreciation right by Mentor Graphics may be made in shares of Mentor Graphics common stock valued at fair market value, or in cash, or partly in shares and partly in cash. The Committee shall either specify the form of payment or retain the power to disapprove any election by a holder to receive cash on exercise of a stock appreciation right. For the purpose of this paragraph, fair market value shall be determined according to subparagraph 5.1(c). (b) Payment upon exercise of a limited stock appreciation right by Mentor Graphics may be made only in cash. 8.4 No fractional shares shall be issued upon exercise of a stock appreciation right. In lieu thereof, cash may be paid in an amount equal to the value of the fraction or, in the discretion of the Committee, the number of shares may be rounded to the next whole share. 8.5 Stock appreciation rights will be subject to such rules, terms, and conditions, and shall be evidenced by an agreement in such form, as the Committee may prescribe prior to the occurrence of a Change in Control. 8.6 Stock appreciation rights may not be assigned or transferred except on death, by will or operation of law, or pursuant to a qualified domestic relations order as defined under the Code or Title I of the Employee Retirement Income Security Act. Stock appreciation rights may be exercised only by the holder or by a successor or representative after death. 8.7 Unless otherwise determined by the Committee, no stock appreciation right may be exercised by an officer of Mentor Graphics subject to Section 16 of the 1934 Act during the first six months following the date of grant. 9. CHANGES IN CAPITAL STRUCTURE. If any change is made in the outstanding common stock without Mentor Graphics' receiving any consideration, such as a stock split, reverse stock split, stock dividend, or combination or reclassification of the common stock, a corresponding change shall be made in the number of shares remaining available for A-5 grants of options or stock appreciation rights under paragraph 1, disregarding fractional shares, without any further approval of the shareholders. The adjustment shall be made by the Committee whose determination shall be conclusive. 10. AMENDMENT OR TERMINATION OF THE PLAN. 10.1 The Board of Directors may amend or terminate this Plan at any time subject to paragraph 10.2. 10.2 Unless the amendment is approved by the shareholders, no amendment shall be made in the Plan that would: (a) Increase the total number of shares available for options or stock appreciation rights; (b) Increase the maximum option term; or (c) Modify the requirements for eligibility under the Plan. A-6
