QUESTIONS AND ANSWERS 1. Q: What may I vote on? A: You are being asked by the Board of Directors of Amerigon to vote on the following four matters: (1) The election of nominees to serve on the Board of Directors. (2) The approval of an amendment to the Certificate of Determination of the Series A Preferred Stock (the "Preferred Stock Amendment"), deleting Subsection 2(c), which specifies certain events deemed to trigger preferential rights of the holders of Series A Preferred Stock in a liquidation, dissolution or winding up of the company, in its entirety. (3) The approval of an amendment to the Articles of Incorporation (the "Articles Amendment"), eliminating the Class B Common Stock and renaming the Class A Common Stock as "Common Stock." (4) The approval of an Amendment to the 1997 Stock Option Plan (the "Option Plan Amendment") to increase the number of shares of Class A Common Stock authorized under the plan from 150,000 to 1,300,000. These four matters are summarized beginning on page 5 and discussed more fully beginning on page 7. 2. Q: How does the Board recommend I vote on the proposals? A: The Board recommends a vote FOR each of the nominees, FOR the approval of the Preferred Stock Amendment, FOR the approval of the Articles Amendment, and FOR the Option Plan Amendment. 3. Q: Who is entitled to vote? A: Shareholders of the Class A Common Stock (the "Common Shareholders") and shareholders of the Series A Preferred Stock (the "Preferred Shareholders") as of the close of business on March 31, 2000 (the "Record Date") are entitled to vote at the Annual Meeting. 4. Q: How do I vote? A: Sign and date each proxy card you receive and return it in the prepaid envelope. You have the right to revoke your proxy at any time before the meeting by: (1) notifying Amerigon in writing; (2) voting in person; or (3) returning a later-dated proxy card.

5. Q: Who will count the vote? A: Representatives of U.S. Stock Transfer Corporation will count the votes and act as the inspector of election. 6. Q: Is my vote confidential? A: Proxy cards, ballots and voting tabulations that identify individual shareholders are mailed or returned directly to U.S. Stock Transfer Corporation and handled in a manner that protects your voting privacy. Your vote will not be disclosed except: (1) as needed to permit U.S. Stock Transfer Corporation to tabulate and certify the vote; (2) as required by law; or (3) in limited circumstances such as a proxy contest in opposition to the Board. 7. Q: What shares are included on the proxy card(s)? A: The shares on your proxy card(s) represent ALL of your shares. If you do not return your proxy card(s), your shares will not be voted. 8. Q: What does it mean if I get more than one proxy card? A: If your shares are registered differently and are in more than one account, you will receive more than one proxy card. Sign and return all proxy cards to ensure that all your shares are voted. We encourage you to have all accounts registered in the same name and address (whenever possible). You can accomplish this by contacting our transfer agent, U.S. Stock Transfer Corporation, at 1745 Gardena Avenue, Suite 200, Glendale, California 91204. 9. Q: What is required to approve each proposal? A: As of the Record Date, 1,914,089 shares of Class A Common Stock and 9,000 shares of Series A Preferred Stock were issued and outstanding. Each Common Shareholder is entitled to one vote for each share held. Each Preferred Shareholder is entitled to one vote for each share of Class A Common Stock into which such Series A Preferred Stock could have been converted on the Record Date. As of the Record Date, the Preferred Shareholders were entitled to convert their shares in 5,373,134 shares of Class A Common Stock. Other than with respect to the election of directors, the Preferred Shareholders are entitled to vote, together with the Common Shareholders, as a single class with respect to any question upon which the Common Shareholders have the right to vote. The Preferred Shareholders have indicated they will vote in favor of each proposal. Once a quorum has been established, the following votes are required to approve each proposal: (1) For the election of directors, the five nominees who receive the most votes of the Series A Preferred Stock and the two nominees who receive the most votes of the Class A Common Stock will become directors of Amerigon. (2) To approve the Preferred Stock Amendment, a majority of the outstanding Series A Preferred Stock and a majority of all outstanding shares of Class A 2

Common Stock and Series A Preferred Stock (on an as-converted basis) must be voted in favor of the amendment. (3) To approve the Articles Amendment, a majority of all outstanding shares of Class A Common Stock and Series A Preferred Stock (on an as-converted basis) must be voted in favor of the amendment. (4) To approve the Option Plan Amendment, a majority of the shares of Class A Common Stock and Series A Preferred Stock (on an as- converted basis) voting at the Annual Meeting must be voted in favor of the amendment. If a broker indicates on its proxy that it does not have discretionary authority to vote on a particular matter, the affected shares will be treated as not present and not entitled to vote with respect to that matter, even though the same shares may be considered present for quorum purposes and may be entitled to vote on other matters. In the absence of instructions, shares represented by valid proxies will be voted as recommended by the directors. 10. Q: What is a "quorum"? A: A "quorum" is a majority of the outstanding shares entitled to vote. They may be present or represented by proxy. For the purposes of determining a quorum, shares held by brokers or nominees will be treated as present even if the broker or nominee does not have discretionary power to vote on a particular matter or if instructions were never received from the beneficial owner. These shares are called "broker non-votes." Abstentions will be counted as present for quorum purposes. 11. Q: Can I cumulate my votes for directors? A: You cannot cumulate votes (i.e., cast a number of votes greater than the number of your shares) for directors unless (1) the nominee's or nominees' names were placed in nomination prior to the election and (2) you gave us notice prior to the commencement of voting of your intention to cumulate votes. As of the date of this proxy statement, we have not received this notice from any shareholders. If you decide to cumulate your votes, and you give us notice of your decision in time, you will be entitled to cast a number of votes equal to the number of shares you hold multiplied by two (the number of directors to be elected) in the case of holders of Class A Common Stock, or five in the case of holders of Series A Preferred Stock. You may then decide to cast these votes for a single nominee or to distribute your votes among two or more nominees. Your proxy will permit Richard A. Weisbart and James L. Mertes to cumulate votes if any shareholder decides to cumulate votes. 12. Q: How will voting on any other business be conducted? A: Although we do not know of any business to be considered at the Annual Meeting other than the proposals described in this proxy statement, if any other business is presented at the Annual Meeting, your signed proxy card gives authority to 3

Richard A. Weisbart and James L. Mertes to vote on such matters at their discretion. 13. Q: When are shareholder proposals for the 2001 Annual Meeting due? A: All shareholder proposals to be considered for inclusion in next year's proxy statement must be submitted in writing to Richard A. Weisbart, President, Amerigon Incorporated, 5462 Irwindale Avenue, Irwindale, California 91706 by January 1, 2001. Any proposal received after this date will be considered untimely. Until further notice, a shareholder proposal (other than in respect of a nominee for election to the Board of Directors) to be presented at the next Annual Meeting of Shareholders but not submitted for inclusion in the proxy statement pursuant to Rule 14a-8 will be considered untimely under the SEC's proxy rules if received after March 16, 2001. Each proposal must comply with the Securities and Exchange Act of 1934, as amended, and the rules and regulations promulgated thereunder. 14. Q: How much did this proxy solicitation cost? A: U.S. Stock Transfer Corporation was hired to assist in the distribution of proxy materials and solicitation of votes for $3,600, plus estimated out-of-pocket expenses of $500. We also reimburse brokerage houses and other custodians, nominees and fiduciaries for their reasonable out-of-pocket expenses for forwarding proxy and solicitation materials to shareholders. 4

PROPOSALS YOU MAY VOTE ON 1. ELECTION OF DIRECTORS. There are seven nominees for election this year. Detailed information on each nominee is provided beginning on page 7. The holders of the Series A Preferred Stock have the right to elect five of the seven seats on the Board of Directors. Roy A. Anderson, John W. Clark, Oscar B. Marx, III, Paul Oster and James J. Paulsen have been nominated for election as directors by the holders of the Series A Preferred Stock. The holders of the Class A Common Stock have the right to elect the remaining two seats on the Board of Directors. Richard A. Weisbart and Lon E. Bell have been nominated for election as directors by the holders of the Class A Common Stock. All directors are elected annually and normally serve a one-year term until the next Annual Meeting. If any of the nominees become unavailable to stand for re-election at the Annual Meeting, the Board will designate a substitute. Proxies voting on the original nominee will be cast for the substitute. Your Board unanimously recommends a vote FOR each of these directors. 2. APPROVAL OF AN AMENDMENT TO THE CERTIFICATE OF DETERMINATION OF THE SERIES A PREFERRED STOCK ELIMINATING SUBSECTION 2(C) IN ITS ENTIRETY. The Certificate of Determination of Rights, Preferences and Privileges of the Series A Preferred Stock (the "Certificate of Determination") designates 9,000 shares of Series A Preferred Stock (the "Preferred Stock") and grants to them various powers, privileges and rights, as well as certain qualifications, limitations and restrictions. Subsection 2(c) of the Certificate of Determination grants to holders of the Preferred Stock preferential rights upon liquidation, dissolution or winding up of Amerigon. This right is triggered by (1) the acquisition of Amerigon by another entity or (2) the sale of all or substantially all of the assets of Amerigon (unless immediately afterwards, prior Amerigon shareholders hold 50% or more of the surviving or acquiring entity). This provision is deemed to be a condition of redemption that is not solely within the control of Amerigon. As such, Amerigon is required for financial reporting purposes to classify the Preferred Stock as mandatorily redeemable or mezzanine equity. Neither Amerigon nor the Preferred Shareholders understood or intended the Preferred Stock to be mezzanine equity, and in March 2000, the Preferred Shareholders waived their rights under subsection 2(c) and agreed to amend the Certificate of Determination to eliminate subsection 2(c). Your Board unanimously recommends a vote FOR the approval of the Preferred Stock Amendment. 3. APPROVAL OF AN AMENDMENT TO THE ARTICLES OF INCORPORATION ELIMINATING THE CLASS B COMMON STOCK. Under our Articles of Incorporation, we are authorized to issue 20,000,000 shares of Class A Common Stock and 600,000 shares of Class B Common Stock. As of the 5

Record Date, we have 1,914,089 shares of Class A Common Stock and no shares of Class B Common Stock outstanding. The Class B Common Stock was all held at one time by Dr. Lon E. Bell, Amerigon's Director of Technology and Vice Chairman of the Board, but has been redeemed by Amerigon in connection with a transaction related to the electric vehicle business approved by our shareholders at the 1999 Annual Meeting. No shares of Class B Common Stock remain outstanding and we have no plans on issuing any such shares in the future. For such reasons, the Board has determined it would be in the best interests of Amerigon to eliminate the Class B Common Stock from the Articles of Incorporation. As a result of the Articles Amendment, the Class A Common Stock will be renamed "Common Stock" and the stock symbol of the common stock will be changed from "ARGNA" to "ARGN." Your Board unanimously recommends a vote FOR the approval of the Articles Amendment. 4. APPROVAL OF AN AMENDMENT TO THE 1997 STOCK OPTION PLAN TO INCREASE CAPACITY FROM 150,000 SHARES TO 1,300,000 SHARES. On June 23, 1999, the Board of Directors unanimously adopted a resolution to increase the capacity of the 1997 Stock Option Plan from 150,000 shares to 1,300,000 shares of Class A Common Stock, subject to shareholder approval, in order to be able to provide equity incentives to employees. Because the capacity of the plan has been exhausted, the Board of Directors believes it is prudent to increase capacity to ensure sufficient shares will be available for grant to new and existing personnel. To date, options for 598,200 shares of Class A Common Stock have been granted by the Board over and above the existing limit of 150,000 shares, subject to shareholder approval. Your Board unanimously recommends a vote FOR the approval of the Articles Amendment INTERESTS OF CERTAIN PERSONS IN MATTERS TO BE ACTED UPON In considering the recommendation of the Board of Directors that you approve the Preferred Stock Amendment, you should be aware that John W. Clark, a member of the Board, is also a general partner of Westar Capital Associates II LLC, an affiliate of one of the two Preferred Shareholders, and that Oscar B. Marx, III and Paul Oster, both members of the Board, are partners in W III H Partners, L.P., the majority owner of the second Preferred Shareholder. See "Certain Transactions--Placement of Preferred Stock." In considering the recommendation of the Board of Directors that you approve the Option Plan Amendment, you should be aware that because the current limit on the number of shares of Class A Common Stock authorized under the 1997 Stock Option Plan has been reached and the Option Plan Amendment will increase the number of such shares available, the non-employee directors on the Board, who are entitled to receive an annual grant of options for 1,000 such shares, have a personal interest in its approval. In addition, Roy A. Anderson and James Paulsen, two non-employee directors, have received options conditioned on shareholder approval of the Option Plan Amendment for 7,500 shares and 15,000 shares, respectively. 6

APPROVAL OF AN AMENDMENT TO THE CERTIFICATE OF DETERMINATION OF THE SERIES A PREFERRED STOCK (Item 2 on Proxy Card) The Certificate of Determination designates 9,000 shares of Series A Preferred Stock and grants to them various powers, privileges and rights, as well as certain qualifications, limitations and restrictions. The Certificate of Determination gives the Preferred Shareholders a liquidation preference in the event of any liquidation, dissolution or winding up of Amerigon, either voluntary or involuntary, and the Preferred Shareholders shall be entitled to receive, before any distribution of assets to the Common Shareholders, an amount per share equal to the sum of (i) $1,000 for each outstanding share of Series A Preferred Stock, (ii) an amount equal to 7% of the original issue price annually, but only until the fourth anniversary of the issuance of the Series A Preferred Stock and (iii) an amount equal to any declared but unpaid dividends on such share. For purposes of the liquidation preference, subsection 2(c) of the Certificate of Determination deems certain events to be a liquidation, dissolution or winding up of Amerigon. These events include (1) the acquisition of Amerigon by another entity by means of any transaction or series of related transactions (including, without limitation, any reorganization, merger or consolidation but, excluding any merger effected exclusively for the purpose of changing the domicile of Amerigon) or (2) the sale of all or substantially all of the assets of 9

Amerigon (unless immediately afterwards, prior Amerigon shareholders hold at least 50% of the voting power of the surviving or acquiring entity). Subsection 2(c) also requires Amerigon to give the Preferred Shareholders 20 days' written notice describing the material terms and conditions of such impending transaction prior to (A) the date of the shareholders' meeting called to approve such transaction, (B) the effective date of a written consent of the shareholders to approve the transaction, or (C) the closing of such transaction, whichever is earlier, and requires Amerigon to notify such holders in writing of the final approval of such transaction. Subsection 2(c) has been deemed to be a condition of redemption that is not solely within the control of Amerigon. Thus, Amerigon is required for financial reporting purposes to classify the Series A Preferred Stock as mandatorily redeemable or mezzanine equity. Since neither Amerigon nor the Preferred Shareholders understood or intended the Series A Preferred Stock to be mezzanine equity, the Board has proposed to eliminate subsection 2(c) from the Certificate of Determination and, in March 2000, the Preferred Shareholders agreed to waive their rights under subsection 2(c) and to support an amendment to the Certificate of Determination eliminating subsection 2(c). Upon approval by the shareholders, a certificate of amendment to the Certificate of Determination will be filed with the California Secretary of State effecting the deletion of subsection 2(c) from the Certificate of Determination. APPROVAL OF AN AMENDMENT TO THE ARTICLES OF INCORPORATION (Item 3 on Proxy Card) Under our Articles of Incorporation, we are authorized to issue 20,000,000 shares of Class A Common Stock and 600,000 shares of Class B Common Stock. As of the Record Date, we had 1,914,089 shares of Class A Common Stock and no shares of Class B Common Stock outstanding. The Articles Amendment would eliminate the Class B Common Stock from our authorized capital structure and reduce the number of authorized shares from 25,600,000 to 25,000,000; the number of authorized shares of Class A Common Stock would remain 20,000,000. As a result of the Articles Amendment, the Class A Common Stock will be renamed "Common Stock" and the stock symbol of the common stock on the Nasdaq Stock Market will be changed from "ARGNA" to "ARGN." The Class A Common Stock and the Class B Common Stock are substantially the same on a share-for-share basis, except that holders of outstanding shares of Class B Common Stock are entitled to receive dividends and distributions upon liquidation at a per share rate equal to five percent of the per share rate received by holders of outstanding shares of Class A Common Stock. The Class B Common Stock is neither transferable nor convertible and is subject to cancellation under certain circumstances. The Class B Common Stock was all held at one time by Dr. Lon E. Bell, our current Chief Technology Officer and Vice Chairman of the Board, but has been redeemed by Amerigon in connection with a transaction related to the electric vehicle business approved by our shareholders at the 1999 Annual Meeting. No shares of Class B Common Stock remain 10

outstanding and we have no plans on issuing any such shares in the future. For such reasons, the Board has approved and unanimously recommended for the approval of the shareholders an amendment to our Articles of Incorporation which eliminates the Class B Common Stock. The text of the Articles Amendment is set forth below: "Article III, paragraphs (1) and (2) of the Corporation's Amended and Restated Articles of Incorporation are amended to read as follows: (1) The total number of shares which the Corporation is authorized to issue is 25,000,000, of which 20,000,000 shall be Common Stock, without par value, and 5,000,000 shall be Preferred Stock, without par value. (2) [Intentionally Deleted]" APPROVAL OF AMENDMENT TO THE 1997 STOCK OPTION PLAN (Item 4 on the Proxy Card) On June 23, 1999, the Board of Directors unanimously adopted a resolution to approve the Option Plan Amendment to the 1997 Stock Option Plan (as so amended, the "1997 Plan" unless the context otherwise dictates) to increase the capacity of the 1997 Plan from 150,000 shares to 1,300,000 shares of Class A Common Stock, subject to shareholder approval, in order to be able to provide equity incentives to employees. Because the capacity of the plan has been exhausted, the Board of Directors believes it is prudent to increase capacity to ensure sufficient shares will be available for grant to new and existing personnel. The Board of Directors approved stock options under the 1997 Plan for 643,500 shares of Class A Common Stock to various employees on June 23, 1999 vesting in equal installments over a 4 year period and expiring on June 22, 2009 at an exercise price of $3.06 per share, which was the fair value of the underlying shares as of the date of grant, conditioned on subsequent shareholder approval of the Option Plan Amendment. The amount approved by the Board exceeded by 598,200 shares the existing limit of 150,000 shares. Awards granted under the 1997 Plan and in excess of the existing limit prior to the Annual Meeting are subject to shareholder approval of the Option Plan Amendment. In the table below, the benefits or amounts to be received by or allocated to each of the following from such grants are: Conditional Awards Granted Name and Position Number of Units Richard A. Weisbart 180,000 President and Chief Executive Officer Lon E. Bell 82,500 Vice Chairman of the Board and Chief Technology Officer 11

Daniel R. Coker 125,000 Vice President of Sales and Marketing James L. Mertes 75,000 Vice President of Quality and Operations Executive Group (1) 462,500 Non-Executive Director Group (2) 22,500 Non-Executive Officer Employee Group (3) 113,200 (1) Consists of all current Executive Officers as a group (4 persons). (2) Consists of two non-executive directors, Messrs. Andersen and Paulsen. (3) Consists of all current non-Executive Officer employees as a group (34 persons) Except for the options already granted, the benefits to be received in 2000 as a result of the Option Plan Amendment by officers, current directors who are not officers and all employees are not determinable, because all grants under the Plan are discretionary (with the exception of the 1,000 options automatically granted each year to Non-Employee Directors). The principal terms of the 1997 Plan are summarized below. The following summary is qualified in its entirety by reference to the full text of the 1997 Plan. The full text of the 1997 Plan is attached as Appendix A. Capitalized terms used herein not otherwise defined have the meanings given to them in the 1997 Plan. Summary Description of the 1997 Plan The 1997 Plan was approved at the 1997 Annual Meeting. The purpose of the 1997 Plan is to promote the success of the Company by providing an additional means through the grant of stock options to attract, retain, motivate and reward key employees (including officers, whether or not directors) of the Company and its related subsidiaries by providing incentives related to equity interests in and the financial performance of the Company. In addition, the 1997 Plan includes an automatic award feature to attract, motivate and retain experienced and knowledgeable outside directors through the grant of fixed nonqualified stock options to them. Administration. The 1997 Plan is administered by the Compensation Committee of the Board of Directors. The 1997 Plan provides that it may be administered by the Board of Directors or a committee consisting of two or more directors (or such greater number of directors as may be required under applicable law) who are (i) in respect of any decision at any time when a Participant affected by the decision may be subject to Section 162(m) of the Internal Revenue Code (the "Code") must be "outside" directors within the meaning of the Code; and (ii) in respect of any decision affecting a transaction at a time when the Participant involved in the transaction may be subject to Section 16 of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), must be "non-employee directors" within the meaning of Rule 16b-3(b)(3) under the Exchange Act. (Hereinafter, the Board or such committee is referred to as the "Committee".) The Committee has the authority to determine the specific terms and conditions of all options granted under the 1997 Plan, including, without limitation, the number of shares subject to each option, the price to be paid for the shares and any other vesting criteria. The 12

Committee makes all other determinations necessary or advisable for the administration of the 1997 Plan. Notwithstanding the foregoing, the award of options to Non-Employee Directors on the first business day of each calendar year is automatic and, to the maximum extent possible, self-effectuating, and the discretion of the Committee does not extend to such options in any manner that would be impermissible under Rule 16b-3 of the Exchange Act. Eligibility. Any officer (whether or not a director) or key employee (an "Eligible Employee") of the Company or its subsidiaries, as determined in the sole discretion of the Committee, is eligible to be granted options under the 1997 Plan. The 1997 Plan also provides that each director who is not an officer or employee of the Company or one of its subsidiaries (a "Non-Employee Director") is automatically granted fixed Nonqualified Stock Options as described below (see "Non-Employee Director Options"). Shares Available for Awards. You are being asked to approve a change in the maximum aggregate number of shares of Common Stock that may be issued upon the exercise of options awarded under the 1997 Plan from 150,000 to 1,300,000, subject to adjustment as described below. 598,200 options have been granted by the Board in excess of the 150,000 originally authorized, pending shareholder approval. Subject to the provisions of the 1997 Plan, the Committee determines the number of shares subject to each option granted to an Eligible Employee and the terms and conditions of such options, including the price to be paid for the shares. Notwithstanding the foregoing, but subject to adjustments as described below, no more than 1,240,000 shares may be delivered upon the exercise of Incentive Stock Options granted under the 1997 Plan. The maximum number of shares of Common Stock which may be delivered pursuant to the exercise of options granted during any calendar year to any Eligible Employee may not exceed 250,000 shares. In addition, the maximum number of shares of Common Stock that may be delivered to Non-Employee Directors pursuant to the exercise of fixed awards may not exceed 60,000 shares. These numbers reflect the 1-for-5 reverse stock split that became effective on January 26, 1999. The number and kind of shares available under the 1997 Plan are subject to adjustment in the event of (i) certain reorganizations, mergers, combinations, recapitalizations, stock splits, stock dividends, or other similar events that change the number or kind of shares outstanding, and (ii) extraordinary dividends or distributions of property to the shareholders. Shares relating to options that are not exercised or that expire or are cancelled will again become available for regrant and award purposes under the 1997 Plan to the extent permitted by law. If an option is settled only in cash, it need not be counted against any of the limits described in the paragraph immediately above. All of the current officers and all of the current Non-Employee Directors of the Company are among those eligible to receive options, subject to the discretion of the Committee to determine the particular individuals who, from time to time, will be selected to receive options. The number of key employees of the Company, if any, who will be eligible to receive options has not been determined at this time. In addition, neither the individuals who are to receive options, nor the number of options that will be granted to any individual or group of individuals, has been determined at this time. 13

Vesting and Option Periods. Except as may be provided in an applicable Option Agreement, no option made under the 1997 Plan may be exercisable or may vest until at least six months after the initial Option Date, and once exercisable, an option will remain exercisable until the expiration or earlier termination of the option. Each option made to an employee will expire on such date as is determined by the Committee, but not later than ten years after the Option Date. Transferability. The 1997 Plan provides, with limited exceptions, that rights or benefits under any option are not assignable or transferable except by will or the laws of descent and distribution, and that only the Participant (or, if the Participant has suffered a disability, his or her legal representative) may exercise the option during the Participant's lifetime. Options Grants to Eligible Employees An option is the right to purchase shares of Common Stock at a future date at a specified price (the "Option Price"). The Option Price of any options granted to Eligible Employees under the 1997 Plan is determined by the Committee at the time of the grant; provided, that the Option Price for Incentive Stock Options granted under the plan may not be less than 100% (110% in the case of an incentive stock option granted to a Participant who owns or is deemed to own more than 10% of the total combined voting power of all classes of stock of the Company) of the Fair Market Value of the Common Stock on the date of grant. An option granted to an Eligible Employee may either be an incentive stock option, as defined in the Code, or a Nonqualified Stock Option. An incentive stock option may not be granted to a person who owns more than 10% of the total combined voting power of all classes of stock of the Company unless the Option Price is at least 110% of the Fair Market Value of shares of Common Stock subject to the option and such option by its terms is not exercisable after expiration of five years from the date such option is granted. To the extent that the aggregate fair market value (defined for this purpose as the fair market value of the stock subject to the options as of the date of grant of the options) of stock with respect to which Incentive Stock Options first become exercisable in any calendar year exceeds $100,000 (taking into account stock subject to Incentive Stock Options granted under the 1997 Plan or any other plan), such options will be treated as Nonqualified Stock Options. Full payment for shares purchased on the exercise of any option, except as provided below, must be made at the time of such exercise (i) in cash or by electronic funds transfer, (ii) by check payable to the order of the Company; (iii) by notice and third party payment in such manner as may be authorized by the Committee; or (iv) by the delivery of shares of Common Stock already owned by the Participant, provided, however, that the Committee may in its discretion limit the Participant's ability to exercise an option by delivering such shares. Termination of Employment. The Committee establishes in respect of each option granted under the 1997 Plan to an Eligible Employee the effect of a termination of employment on the rights and benefits thereunder and in so doing may make distinctions based upon the cause of termination or otherwise. 14

Options to Non-Employee Directors The 1997 Plan provides that each Non-Employee Director then in office will automatically be granted, on the first business day of each calendar year during the term of the 1997 Plan, commencing in 1998, a Nonqualified Stock Option to purchase 1,000 shares of Common Stock. The purchase price per share of Common Stock covered by each such option granted to a Non-Employee Director, payable in cash or shares of Common Stock, will be the Fair Market Value of the Common Stock on the Option Date. Any previously owned shares used in payment of the exercise price must have been owned by the Non-Employee Director at least six months prior to the date of exercise. The options become exercisable on the first anniversary of the Option Date and, unless earlier terminated, expire ten years after the Option Date. In the event that a Non-Employee Director's service as a member of the Board of Directors is terminated for any reason other than the death, Total Disability or retirement of such director, any portion of an Option granted to such individual which is not then exercisable will terminate, and any portion of such Option which is then exercisable will remain exercisable for two years after such service terminates or until the expiration of the stated term of such Option, whichever occurs first. If a Non-Employee Director's service as a member of the Board is terminated by reason of the death or Total Disability of such director, then all options granted to such director under the 1997 Plan (whether or not vested at such time) become immediately exercisable and may be exercised for a period of two years after the effective date of such director's termination of service on the Board or until the original expiration of the options, whichever first occurs. In the event that a Non-Employee Director retires on or after age 65 and after 10 years of service as a director, all options granted to such director will become immediately exercisable and may be exercised for five years after the date of retirement or until the expiration of the stated term of the option, whichever first occurs. Other Provisions Adjustments; Acceleration. The 1997 Plan provides for certain adjustments to options granted under the Plan upon the occurrence of certain specified events. The number and kind of shares available under the 1997 Plan, as well as the number, kind and price of shares subject to outstanding options, are subject to adjustment in the event of a reorganization, merger, sale of assets, recapitalization, stock split, stock dividend, exchange offer or similar event. Adjustments to options granted to Non-Employee Directors may only be made to the extent that such adjustments (i) are consistent with applicable law, (ii) are, in the case of a Change in Control Event, effected pursuant to a plan of reorganization approved by shareholders, and (iii) are consistent with adjustments to options granted under the 1997 Plan held by persons other than executive officers or directors of the Company. The 1997 Plan also provides for full vesting and acceleration of options (subject to certain limitations applicable to persons subject to Section 16 of the Exchange Act) in the event of a Change in Control Event affecting the Company. The Committee, however, prior to the Change in Control Event, may determine that there will be no such acceleration of benefits. (A Change in Control Event is generally defined to include liquidation of the Company, the sale of substantially all of the Company's business or assets, an acquisition by one person (or group of 15

persons) of at least 20% of the ownership of the Company, the replacement of the majority of the members of the incumbent Board of Directors (excluding replacement directors nominated by the incumbent Board of Directors), or mergers and similar transactions which result in a 50% change in ownership, subject to certain exceptions.) Tax Withholding. Upon exercise of any option, the Company has the right at its option to (i) require the Participant to pay or provide for payment of the amount of any taxes which the Company may be required to withhold with respect to such option event or payment or (ii) deduct from any amount payable in cash the amount of any taxes which the Company may be required to withhold with respect to such cash payment. In any case where a tax is required to be withheld in connection with the delivery of shares of Common Stock, the Committee may in its sole discretion grant to the Participant the right to elect, pursuant to such rules and subject to such conditions as the Committee may establish, to have the Company reduce the number of shares to be delivered by (or otherwise reacquire) the appropriate number of shares valued at their then Fair Market Value to satisfy such withholding obligation. Termination of or Changes to the 1997 Plan. The authority to grant new options under the 1997 Plan terminates on April 24, 2007, unless the 1997 Plan is terminated prior to that time by the Board of Directors. Such termination typically will not affect rights of participants, which accrue prior to such termination. The Board of Directors may, without shareholder approval, terminate, suspend or amend the 1997 Plan at any time. However, the Board of Directors may not increase the maximum number of shares which may be delivered pursuant to options granted under the 1997 Plan, materially increase the benefits accruing to Participants under the 1997 Plan or materially change the requirements as to eligibility to participate in the 1997 Plan. Amendment of the 1997 Plan will not, without the written consent of a Participant, adversely affect such Participant's rights under an option previously granted. Amendments to Options. Subject to certain limitations, the Committee may waive conditions of or limitations on options to Eligible Employees without the consent of a Participant. In addition, the Committee may make other changes to the terms and conditions of options that do not affect in any manner materially adverse to the Participant, his or her rights and benefits under an option. However, the Committee may not, without prior shareholder approval (except in the case of an adjustment as provided under the plan), (i) authorize the amendment of outstanding options to reduce the exercise price, or (ii) cancel and replace outstanding options with similar options having an exercise or base price that is lower. Federal Income Tax Consequences of Options Under the 1997 Plan The federal income tax consequences of the 1997 Plan under current federal law, which is subject to change, are summarized in the following discussion, which deals with the general tax principles applicable to the 1997 Plan. State and local tax consequences are beyond the scope of this summary. Nonqualified Stock Options. No taxable income will be realized by an option holder upon the grant of a Nonqualified Stock Option under the 1997 Plan. When the holder exercises the Nonqualified Stock Option, however, he or she will generally recognize ordinary income equal to the difference between the option price and the fair market value of the shares at the 16

time of exercise. The Company is generally entitled to a corresponding deduction at the same time and in the same amounts as the income recognized by the option holder. Upon a subsequent disposition of the Common Stock, the option holder will realize short-term or long-term capital gain or loss, depending on how long the Common Stock is held. The Company will not be entitled to any further deduction at that time. Incentive Stock Options. An employee who is granted an Incentive Stock Option under the 1997 Plan does not recognize taxable income either on the date of its grant or on the date of its exercise, provided that, in general, the exercise occurs during employment or within three months after termination of employment. However, any appreciation in value of the Common Stock after the date of the grant will be includable in the participant's federal alternative minimum taxable income at the time of exercise in determining liability for the alternative minimum tax. If Common Stock acquired pursuant to an Incentive Stock Option is not sold or otherwise disposed of within two years from the date of grant of the option nor within one year after the date of exercise, any gain or loss resulting from disposition of the Common Stock will be treated as long- term capital gain or loss. If stock acquired upon the exercise of an Incentive Stock Option is disposed of prior to the expiration of such holding periods (a "Disqualifying Disposition"), the participant generally will recognize ordinary income at the time of such Disqualifying Disposition equal to the difference between the exercise price and the fair market value of the Common Stock on the date the Incentive Stock Option is exercised or, if less, the excess of the amount realized on the Disqualifying Disposition over the exercise price. Any remaining gain or net loss is treated as a short-term or long-term capital gain or loss, depending upon how long the Common Stock is held. Unlike the case in which a Nonqualified Stock Option is exercised, the Company is not entitled to a tax deduction upon either the grant or exercise of an Incentive Stock Option or upon disposition of the Common Stock acquired pursuant to such exercise, except to the extent that the employee recognizes ordinary income in a Disqualifying Disposition. Special Rules Governing Persons Subject to Section 16(b). Under the federal tax law, special rules may apply to participants in the 1997 Plan who are subject to the restrictions on resale of the Company's Common Stock under Section 16(b) of the Exchange Act. These rules, which effectively take into account the Section 16(b) restrictions, apply in limited circumstances and may impact the timing or amount of income recognized by these persons with respect to options under the 1997 Plan. Accelerated Payments. If, as a result of certain changes in control of the Company, a participant's options become immediately exercisable, the additional economic value, if any, attributable to the acceleration may be deemed a "parachute payment." The additional value generally will be deemed a parachute payment if such value, when combined with the value of other payments that are deemed to result from the change in control, equals or exceeds a threshold amount equal to 300% of the participant's average annual taxable compensation over the five calendar years preceding the year in which the change in control occurs. In such case, the excess of the total parachute payments over such participant's average annual taxable compensation will be subject to a 20% non- deductible excise tax in addition to any income tax payable. The Company will not be entitled to a deduction for that portion of any parachute payment, which is subject to the excise tax. 17

Section 162(m) Limits. Notwithstanding the foregoing discussion with respect to the deductibility of compensation under the 1997 Plan by the Company, Section 162(m) of the Code would render non-deductible to the Company certain compensation to certain employees required to be named in the Summary Compensation Table (i.e., the Named Executive Officers) in excess of $1,000,000 in any year unless such excess compensation is "performance-based" (as defined in the Code) or is otherwise exempt from these new limits on deductibility. The applicable conditions of an exemption for performance-based compensation plans include, among others, a requirement that the shareholders approve the material terms of the plan. The Company believes that options granted (to the extent granted at a price not less than market price on the date of grant) are exempt from such limits as performance-based compensation. However, in light of uncertainties regarding its ultimate interpretation, no assurances can be given that all compensation intended to so qualify will in fact be deductible, if the nonqualifying amount should, together with other non-exempt compensation, paid to a Named Executive Officer, exceed $1,000,000. As of the date of this Proxy Statement, no Named Executive Officer of the Company has ever received compensation in excess of $1,000,000 in any year. Specific Benefits. Except for the fixed annual option grants to Non- Employee Directors and the conditional awards granted described above, the number of options to be granted to Participants under the 1997 Plan in addition to is subject to the discretion of the Committee and is therefore not determinable. In addition, the gains, if any, to be realized by optionees upon exercise of any options granted under the 1997 Plan are dependent on the future performance of the Common Stock and on overall market conditions and cannot be determined or estimated at this time. STATEMENT ON CORPORATE GOVERNANCE Board Operations and Meetings The Board held five meetings during 1999, and all of the directors attended at least 75% of the Board meetings. In addition, all of the directors attended at least 75% of the committee meetings of which they were members. Committee Structure Although the full Board considers all major decisions of Amerigon, the Board has established two standing committees to more fully address certain areas of importance to Amerigon. The Board has established the following two committees, each of which is comprised only of non-employee Directors: . Audit Committee: The Audit Committee provides advice and assistance to the Board of Directors on accounting and financial reporting practices of Amerigon. It also reviews the scope of audit work and findings of the firm of independent public accountants who serve as auditors of Amerigon and monitors the work of Amerigon's internal auditors. The Audit Committee consists of Messrs. Anderson, Clark, and Paulsen. The Audit Committee held no meetings in 1999. 18

. Compensation Committee: The Compensation Committee reviews and makes recommendations to the Board of Directors concerning the compensation arrangements of Amerigon's executive officers and administers the 1997 Stock Option Plan to determine awards to be made thereunder. The Compensation Committee consists of Messrs. Anderson, Clark, and Paulsen. The Compensation Committee held two meetings in 1999. DIRECTORS' COMPENSATION No retainer, consulting, or other fees (other than reimbursement for expenses incurred in attending Board of Directors and committee meetings) are paid to Directors as consideration for their service to Amerigon in their capacity as directors, except for the options described below. Pursuant to the 1997 Stock Option Plan, each Non-Employee Director of Amerigon is automatically granted options to purchase 1,000 shares of Class A Common Stock on the first business day of each calendar year. The exercise price of these options is the fair market value of shares of the Class A Common Stock on the date of the grant and the option has a term of ten years (subject to reduction under certain circumstances). In addition, on June 23, 1999, two non-employee directors, Roy A. Anderson and James Paulsen, who were not affiliated with either Big Beaver or Westar Capital, were awarded additional grants of stock options by the Board of Directors (with Messrs. Anderson and Paulson abstaining from such decision), because the Board believed that these individuals should receive equity compensation in addition to that which would be awarded under the 1997 Stock Option Plan as non-employee directors. The Board noted that Mr. Anderson already had certain options because of his previous service and that Mr. Paulsen had no stock ownership and, thus, awarded grants of 7,500 shares and 15,000 shares of Class A Common Stock, respectively. Each grant had a term of 10 years, vesting over four years and with an exercise price equal to the fair market value on the date of grant. 19

PERFORMANCE GRAPH The graph below compares the performance of the Class A Common Stock to that of the Nasdaq Stock Market -- US Companies Index and the Nasdaq Non- Financial Index for the period commencing December 31, 1993 and ending December 31, 1999. During this period, Amerigon has been in the development stage. The indexes assume that the value of the investment in Amerigon's common stock and in each index was $100 on December 31, 1993. The total shareholder returns depicted in the graph are not necessarily indicative of future performance.

REPORT OF THE COMPENSATION COMMITTEE ON EXECUTIVE COMPENSATION The directors comprising the Compensation Committee are Messrs. Anderson, Clark, and Paulsen. The Committee determines the compensation of the directors and executive officers of Amerigon, including the compensation in the form of stock options under Amerigon's 1997 Stock Option Plan. Amerigon's executive compensation programs are designed to provide competitive levels of compensation in order to attract, retain and motivate highly qualified employees; tie individual total compensation to individual and Amerigon performance; and align the interests of directors and executive officers with those of Amerigon's shareholders. Amerigon's executive compensation consists of three components: base salary, bonus and stock options. Base Salaries. In determining salaries for executive officers, the Committee reviews base salary ranges for competitive positions in the market. The Committee generally attempts to set base salary at or near the midpoint of prevailing salaries for comparable positions at comparable companies. In determining annual increases in base salary, the Committee considers (in addition to competitive factors) the recommendations of Amerigon's Chief Executive Officer and, in some instances, other members of senior management, although no officer makes recommendations or participates in decisions with respect to his or her own compensation. Management's recommendations and the Committee's determinations are based on a subjective 22

assessment of the relative contributions made by the executive officer to the success of Amerigon in achieving its strategic objectives. Such contributions are measured on the basis of various subjective and objective criteria, which are appropriate for the officer's position and responsibilities within Amerigon. Examples of such criteria include leadership, division or department performance relative to Amerigon's budget and strategic plan for the year, achievement of certain project milestones, and improvements in customer satisfaction. Bonuses. The Committee may, in its discretion, award cash bonuses to executive officers as an additional performance incentive and to recognize extraordinary contributions to Amerigon's performance relative to its strategic plan. Such bonuses are subjectively determined by the Committee using substantially the same processes and factors as are described above for determining salary increases, but without regard to competitive factors. The Committee also favors performance-based bonuses relating to achievement of milestone objectives. CCS(TM) Incentive Bonus Plan. At its June 16, 1998 meeting, the Board of Directors adopted a "Project CCS Incentive Bonus Plan" to provide incentives for all employees to contribute to the success of the CCS project. All full-time employees of Amerigon on or after January 1, 1998 were eligible participants in the Plan. Bonuses under the Plan were awarded and calculated based on whether certain sales and production goals for Climate Control Seats(TM) were achieved, with five different "tiers" of job classifications being eligible for bonuses of varying percentages of annual salary. These percentages increase proportionally with the degree of involvement in the development of CCS products of the employees in that classification. The largest bonus payable under the Plan would be awarded to "Tier I" employees (i.e., the Chief Executive Officer and the Chief Operating Officer) when all three goals of the program were met, and would be equal to one year's salary. The various production goals were met in 1999 and 2000, and the CCS Incentive Bonus Plan has been completed as of March 31, 2000. Stock Options. Options to purchase Amerigon's Common Stock may be granted to executive officers under the 1997 Stock Option Plan in the discretion of the Compensation Committee. The Committee believes that such option grants link the interests of management and shareholders by incentifying management to build shareholder value. Stock options are typically granted to an executive officer as an inducement to commence employment with Amerigon. Thereafter, additional grants of stock options may be made to such executive officer in the discretion of the Compensation Committee to reward the performance of such officer or for other reasons. In determining option grants, the Compensation Committee considers a number of factors (including the officer's performance, his or her position within Amerigon, and the number of shares or options currently held by the officer), although the Compensation Committee does not attach greater weight to any one factor over the others. Other Perquisites and Compensation. Mr. Weisbart is the beneficiary of a Supplemental Executive Retirement Plan (SERP). Under the terms of the SERP, the Company agrees that it will establish, in its sole discretion, an investment account into which it may make annual cash contributions that it will invest in its discretion after consultation with Mr. Weisbart. The Company, in its good faith discretion, will pay to Mr. Weisbart upon his retirement at age 65 and for a 10-year period thereafter, annual retirement payments out of the investment account to the extent the Company determines in good faith that the value of his stock option plan is less than 23

$1,000,000. The SERP is an unsecured obligation of the Company, and is an unfunded plan within the meaning of the Employee Retirement Income Security Act of 1974 (ERISA). The Company entered this agreement with Mr. Weisbart because since his employment by the Company on May 5, 1997, he has acquired experience and knowledge of considerable value to the Company. It is in the Company's best interest to offer the SERP, thereby compensating him beyond his regular salary, as an inducement to Mr. Weisbart to remain in its employ. Internal Revenue Code Section 162(m). Given the current compensation levels of Amerigon's executive officers and Amerigon's reported losses for federal income tax purposes, the Committee does not presently anticipate that the limitation contained in Section 162(m) of the Internal Revenue Code will affect the deductibility of compensation paid by Amerigon to its executive officers. Roy A. Anderson John W. Clark James J. Paulsen COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION During the fiscal year ended December 31, 1999, Roy A. Anderson, John W. Clark and James J.

CERTAIN TRANSACTIONS Loan by Big Star In March 2000, we obtained a loan from Big Star LLC (a limited liability company owned by Westar Capital and Big Beaver, our two largest shareholders) for an initial advance of $1.5 million and, at our request and subject to Big Star's sole discretion, additional advances of up to an additional $2.5 million. The principal and accrued interest of the initial loan is convertible at any time into Class A Common Stock at a conversion price equal to $18.8375. Additional advances will also be convertible based on the average price of the Class A Common Stock during the ten days preceding such additional advances. The conversion price of all advances will be adjusted in the event we raise in excess of $5 million through the sale of equity securities at an issuance price that is less than the then stated conversion price. The adjusted conversion in such event will be the price at which such equity securities are sold. The loans are due on August 31, 2000 and are secured by substantially all of our assets. Warrants to purchase Class A Common Stock were also issued in connection with the loan for an amount equal to 10% of the principal amount of the advances made divided by the conversion price (approximately 8,000 shares). The exercise price for the warrants and adjustments to their exercise price is the same as for the loans. Placement of Preferred Stock On June 8, 1999, we completed a private placement of 4,500 shares of Preferred Stock to Westar Capital and 4,500 shares to Big Beaver pursuant to a Securities Purchase Agreement dated March 29, 1999. The Preferred Shareholders, which are both private investment companies, paid consideration in an aggregate amount of $9,001,000 for the Preferred Stock as well as contingent warrants which are exercisable to the extent that warrants held by entities other than the Preferred Shareholders are exercised. The Preferred Stock has voting rights equal to the number of shares of Class A Common Stock that the Preferred Stock is convertible. The Preferred Stock can convert into a number of shares of the Class A Common Stock, no par value, equal to the Preferred Stock's liquidation preference divided by the conversion price. Each share of Preferred Stock has a liquidation preference equal to $1,000 plus accrued but unpaid dividends and an initial conversion price of $1.675, subject to anti-dilution adjustment. Pursuant to the terms of the Preferred Stock, the size of the Board of Directors was fixed at seven and the holders of the Preferred Stock have the right to elect five of the seven directors. The Preferred Shareholders have agreed to vote for two nominees selected by Westar, two nominees selected by Big Beaver and one nominee mutually agreeable to the Preferred Shareholders who is an auto industry expert. As of the Record Date, the Preferred Stock purchased by the Preferred Shareholders represented approximately 74% of our common equity (on an as-converted basis, excluding options and warrants). Mr. Clark, a director of the Company, is a general partner of Westar Capital Associates II LLC, an affiliate of Westar Capital. Mr. Marx, Chairman of the Board of the Company, is Chief Executive Officer of Big Beaver and Mr. Oster, a director of the Company, is Chief Financial Officer of Big Beaver. Both of these companies 27

are partners in the credit facility. Further, Mr. Marx and Mr. Oster are partners in W III H Partners, L.P., the majority owner of Big Beaver. This transaction, combined with Mr. Clark's, Mr. Marx's and Mr. Oster's membership on the Board of Directors, could give rise to conflicts of interest. Sale of Electric Vehicle Assets When the Board of Directors decided in 1998 to suspend funding the electric vehicle program (effective August 1998), Dr. Bell, at that time Chairman of the Board, believed that there were still commercial opportunities worth pursuing and agreed to fund the program personally in return for a 15% interest in the subsidiary in which the electric vehicle assets were to be placed (the "AEVT"). In connection with the Company's June 1999 financing, in a transaction that was approved by the Company's shareholders in May 1999, Dr. Bell sold all of his Class B Common Stock of Amerigon in exchange for the remaining 85% interest in AEVT. AEVT's License of Amerigon's CCS In April of 1999, Amerigon granted a royalty-free license (the "Agreement") to AEVT Incorporated ("AEVT") to use CCS technology in connection with the use, manufacture, advertisement, marketing, and sale of electric vehicles in India, Sri Lanka, Bangladesh, Pakistan, Nepal, Myanmar, Seychelles, and Maldives (the "Territory"). Dr. Bell is director and the controlling shareholder of AEVT, a company developing electric vehicles that at one time was a subsidiary of Amerigon. The Agreement was entered to enable AEVT to perform its obligations under the December 16, 1998 letter agreement between AEVT and Sudarshan K. Maini, Maini Materials Movement and Maini Precision Products, Pvt. Ltd. The Agreement provides that AEVT may purchase CCS modules from Amerigon at the same price that Amerigon charges its principal customers, and that AEVT may purchase CCS parts from Amerigon at 110% of their production cost. AEVT agreed to pay Amerigon for any royalties or other fees that Amerigon is required to pay to those it has licensed patents or other intellectual property from as a result of the Agreement. Amerigon also agreed to provide reasonable technical assistance to AEVT, including allowing an AEVT representative to study its production and design facilities for a period of six weeks. The Agreement also allows AEVT to export complete electric vehicles containing CCS technology to customers outside of the Territory. 28

INDEPENDENT ACCOUNTANTS PricewaterhouseCoopers LLP served as Amerigon's independent accountants for the fiscal year ended December 31, 1999, and is expected to continue to serve in such capacity for the current year. A representative of PricewaterhouseCoopers LLP will be present at the Annual Meeting and will have the opportunity to make a statement if they so choose. They will also be available to respond to appropriate questions at such time. SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE Based solely on a review of the relevant forms and written representations furnished to Amerigon, there were three reports required by Section 16(a) of the Exchange Act that were not timely filed during the fiscal year ended December 31, 1999. Each of Messrs. Anderson, Paulsen and Bell reported transactions on a Form 4, Statement of Changes of Beneficial Ownership, which was not timely filed. OTHER MATTERS If any matters not referred to in this proxy statement should properly come before the meeting, your "proxy" will vote your shares represented by the proxy in accordance with his or her judgment. We are not aware of any such matters which may be presented for action at the meeting. Your proxy may also vote your shares on matters regarding the conduct of the meeting.

AMERIGON INCORPORATED 1997 STOCK INCENTIVE PLAN AS AMENDED ON JUNE 23, 1999 1. THE PLAN. 1.1 Purpose. ------- The purpose of this Plan is to promote the success of the Company by providing an additional means through the grant of Options to attract, motivate, retain and reward key employees, including officers, whether or not directors, of the Company with awards and incentives for high levels of individual performance and improved financial performance of the Company and to attract, motivate and retain experienced and knowledgeable independent directors through the benefits provided under Article 3. "Corporation" means Amerigon Incorporated and "Company" means the Corporation and its Subsidiaries, collectively. These terms and other capitalized terms are defined in Article 5. 1.2 Administration and Authorization; Power and Procedure. ----------------------------------------------------- (a) Committee. This Plan shall be administered by and all Options to --------- Eligible Employees shall be authorized by the Committee. Action of the Committee with respect to the administration of this Plan shall be taken pursuant to a majority vote or by written consent of its members. (b) Plan Awards; Interpretation; Powers of Committee. Subject to the ------------------------------------------------ express provisions of this Plan, the Committee shall have the authority: (i) to determine from among those persons eligible the particular Eligible Employees who will receive any Options; (ii) to grant Options to Eligible Employees, determine the price at which securities will be offered and the amount of securities to be offered to any of such persons, and determine the other specific terms and conditions of such Options consistent with the express limits of this Plan, and establish the installments (if any) in which such Options shall become exercisable or shall vest, or determine that no delayed exercisability or vesting is required, and establish the events of termination of such Options;

(iii) to approve the forms of Option Agreements (which need not be identical either as to type of award or among Participants); (iv) to construe and interpret this Plan and any agreements defining the rights and obligations of the Company and Participants who are granted Options under Article 2 of this Plan, further define the terms used in this Plan, and prescribe, amend and rescind rules and regulations relating to the administration of this Plan; (v) to cancel, modify, or waive the Corporation's rights with respect to, or modify, discontinue, suspend, or terminate any or all outstanding Options held by Eligible Employees, subject to any required consent under Section 4.6; (vi) to accelerate or extend the exercisability or extend the term of any or all such outstanding Options within the maximum ten- year term of Options under Section 1.6; and (vii) to make all other determinations and take such other action as contemplated by this Plan or as may be necessary or advisable for the administration of this Plan and the effectuation of its purposes. Notwithstanding the foregoing, the provisions of Article 3 relating to Non- Employee Director Options shall be automatic and, to the maximum extent possible, self-effectuating, and the discretion of the Committee shall not extend to such Options in any manner that would be impermissible under Rule 16b-3. (c) Binding Determinations. Any action taken by, or inaction of, the ---------------------- Corporation, any Subsidiary, the Board or the Committee relating or pursuant to this Plan shall be within the absolute discretion of that entity or body and shall be conclusive and binding upon all persons. No member of the Board or Committee, or officer of the Corporation or any Subsidiary, shall be liable for any such action or inaction of the entity or body, of another person or, except in circumstances involving bad faith, of himself or herself. Subject only to compliance with the express provisions hereof, the Board and Committee may act in their absolute discretion in matters within their authority related to this Plan. (d) Reliance on Experts. In making any determination or in taking or ------------------- not taking any action under this Plan, the Committee or the Board, as the case may be, may obtain and may rely upon the advice of experts, including professional advisors to the Corporation. No director, officer or agent of the Company shall be liable for any such action or determination taken or made or omitted in good faith. (e) Delegation. The Committee may delegate ministerial, non- ---------- discretionary functions to individuals who are officers or employees of the Company. 2

1.3 Participation. ------------- Options may be granted by the Committee only to those persons that the Committee determines to be Eligible Employees. An Eligible Employee who has been granted an Option may, if otherwise eligible, be granted additional Options if the Committee shall so determine. Non-Employee Directors shall only be eligible to receive Nonqualified Stock Options granted automatically without action of the Committee under the provisions of Article 3. 1.4 Shares Available for Options; Share Limits. ------------------------------------------ (a) Shares Available. Subject to the provisions of Section 4.2, the ---------------- capital stock that may be delivered under this Plan shall be shares of the Corporation's authorized but unissued Common Stock and any shares of its Common Stock held as treasury shares. The shares may be delivered for any lawful consideration. (b) Share Limits. The maximum number of shares of Common Stock that ------------ may be delivered pursuant to all Options (including both Nonqualified Stock Options and Incentive Stock Options) granted under this Plan shall not exceed 1,300,000 shares (the "Share Limit"). The maximum number of shares of Common Stock that may be delivered pursuant to options qualified as Incentive Stock Options granted under this Plan is 1,240,000 shares. The maximum number of shares of Common Stock that may be delivered to Non-Employee Directors under the provisions of Article 3 shall not exceed 60,000 shares. The maximum number of shares subject to those options that are granted during any calendar year to any Eligible Employee shall be limited to 250,000. Each of the four foregoing numerical limits shall be subject to adjustment as contemplated by this Section 1.4 and Section 4.2. (c) Share Reservation; Replenishment and Reissue of Unvested Options. ---------------------------------------------------------------- No Option may be granted under this Plan unless, on the date of grant, the sum of (i) the maximum number of shares issuable at any time pursuant to such Option, plus (ii) the number of shares that have previously been issued pursuant to Options granted under this Plan, other than reacquired shares available for reissue consistent with any applicable limitations, plus (iii) the maximum number of shares that may be issued at any time after such date of grant pursuant to Options that are outstanding on such date, does not exceed the Share Limit. Shares that are subject to or underlie Options which expire or for any reason are cancelled or terminated, are forfeited, fail to vest, or for any other reason are not paid or delivered under this Plan, as well as reacquired shares, shall again, except to the extent prohibited by law, be available for subsequent Options under this Plan. Except as limited by law, if an Option is settled only in cash, such Option need not be counted against any of the limits under this Section 1.4. 3

1.5 Grant of Option. --------------- Subject to the express provisions of this Plan, the Committee shall determine the number of shares of Common Stock subject to each Option and the price to be paid for the shares. Each Option shall be evidenced by an Option Agreement signed by the Corporation and, if required by the Committee, by the Participant. 1.6 Option Period. ------------- Each Option and all executory rights or obligations under the related Option Agreement shall expire on such date (if any) as shall be determined by the Committee, but not later than ten (10) years after the Option Date. 1.7 Limitations on Exercise and Vesting of Options. ---------------------------------------------- (a) Provisions for Exercise. Unless the Committee otherwise expressly ----------------------- provides, no Option shall be exercisable or shall vest until at least six months after the initial Option Date, and once exercisable an Option shall remain exercisable until the expiration or earlier termination of the Option. (b) Procedure. Any exercisable Option shall be deemed to be exercised --------- when the Secretary of the Corporation receives written notice of such exercise from the Participant, together with any required payment made in accordance with Section 2.2(a) or 3.3, as the case may be. (c) Fractional Shares/Minimum Issue. Fractional share interests shall ------------------------------- be disregarded, but may be accumulated. The Committee, however, may determine in the case of Eligible Employees that cash, other securities, or other property will be paid or transferred in lieu of any fractional share interests. No fewer than 100 shares may be purchased on exercise of any Option at one time unless the number purchased is the total number at the time available for purchase under the Option. 1.8 No Transferability. ------------------ (a) Limit on Exercise and Transfer. Unless otherwise expressly ------------------------------ provided in (or pursuant to) this Section 1.8, by applicable law and by the Option Agreement, as the same may be amended, (i) all Options are non-transferable and shall not be subject in any manner to sale, transfer, anticipation, alienation, assignment, pledge, encumbrance or charge; (ii) Options shall be exercised only by the Participant; and (iii) amounts payable or shares issuable pursuant to an Option shall be delivered only to (or for the account of) the Participant. (b) Exceptions. The Committee may permit Options to be exercised by ---------- and paid to certain persons or entities related to the Participant pursuant to such conditions and procedures as the Committee may establish. Any 4

permitted transfer shall be subject to the condition that the Committee receive evidence satisfactory to it that the transfer is being made for estate and/or tax planning purposes or a gratuitous or donative basis and without consideration (other than nominal consideration). Notwithstanding the foregoing, Incentive Stock Options shall be subject to any and all applicable transfer restrictions under the Code. (c) Further Exceptions to Limits On Transfer. The exercise and ---------------------------------------- transfer restrictions in Section 1.8(a) shall not apply to: (i) transfers to the Corporation, (ii) the designation of a beneficiary to receive benefits in the event of the Participant's death or, if the Participant has died, transfers to or exercise by the Participant's beneficiary, or, in the absence of a validly designated beneficiary, transfers by will or the laws of descent and distribution, (iii) transfers pursuant to a QDRO order, (iv) if the Participant has suffered a disability, permitted transfers or exercises on behalf of the Participant by his or her legal representative, or (v) the authorization by the Committee of "cashless exercise" procedures with third parties who provide financing for the purpose of (or who otherwise facilitate) the exercise of Awards consistent with applicable laws and the express authorization of the Committee. Notwithstanding the foregoing, Incentive Stock Options shall be subject to all applicable transfer restrictions under the Code. 2. EMPLOYEE OPTIONS. 2.1 Grants. ------ One or more Options may be granted under this Article to any Eligible Employee. Each Option granted may be either an Option intended to be an Incentive Stock Option, or not so intended, and such intent shall be indicated in the applicable Option Agreement. 2.2 Option Price. ------------ (a) Pricing Limits. The purchase price per share of the Common Stock -------------- covered by each Option shall be determined by the Committee at the time of the grant, but in the case of Incentive Stock Options shall not be less than 100% (110% in the case of a Participant who owns or is deemed to own under Section 424(d) of the Code more than 10% of the total 5

combined voting power of all classes of stock of the Corporation) of the Fair Market Value of the Common Stock on the date of grant. (b) Payment Provisions. The purchase price of any shares purchased on ------------------ exercise of an Option granted under this Article shall be paid in full at the time of each purchase in one or a combination of the following methods: (i) in cash or by electronic funds transfer; (ii) by check payable to the order of the Corporation; (iii) by notice and third party payment in such manner as may be authorized by the Committee; or (iv) by the delivery of shares of Common Stock of the Corporation already owned by the Participant, provided, however, that the -------- ------- Committee may in its absolute discretion limit the Participant's ability to exercise an Option by delivering such shares. Shares of Common Stock used to satisfy the exercise price of an Option shall be valued at their Fair Market Value on the date of exercise. 2.3 Limitations on Grant and Terms of Incentive Stock Options. --------------------------------------------------------- (a) $100,000 Limit. To the extent that the aggregate "fair market -------------- value" of stock with respect to which incentive stock options first become exercisable by a Participant in any calendar year exceeds $100,000, taking into account both Common Stock subject to Incentive Stock Options under this Plan and stock subject to incentive stock options under all other plans of the Company or any parent corporation, such options shall be treated as nonqualified stock options. For this purpose, the "fair market value" of the stock subject to options shall be determined as of the date the options were awarded. In reducing the number of options treated as incentive stock options to meet the $100,000 limit, the most recently granted options shall be reduced first. To the extent a reduction of simultaneously granted options is necessary to meet the $100,000 limit, the Committee may, in the manner and to the extent permitted by law, designate which shares of Common Stock are to be treated as shares acquired pursuant to the exercise of an Incentive Stock Option. (b) Option Period. Each Option and all rights thereunder shall expire ------------- no later than ten years after the Option Date. (c) Other Code Limits. There shall be imposed in any Option Agreement ----------------- relating to Incentive Stock Options such terms and conditions as from time to time are required in order that the Option be an "incentive stock option" as that term is defined in Section 422 of the Code. 2.4 Limits on 10% Holders. --------------------- No Incentive Stock Option may be granted to any person who, at the time the Option is granted, owns (or is deemed to own under Section 424(d) of the Code) shares of outstanding Common Stock possessing more than 10% of the total combined 6

voting power of all classes of stock of the Corporation, unless the exercise price of such Option is at least 110% of the Fair Market Value of the stock subject to the Option and such Option by its terms is not exercisable after the expiration of five years from the date such Option is granted. 2.5 Cancellation and Regrant/Waiver of Restrictions. ----------------------------------------------- Subject to Section 1.4 and Section 4.6 and the specific limitations on Options contained in this Plan, the Committee from time to time may authorize, generally or in specific cases only, for the benefit of any Eligible Employee any adjustment in the number of shares subject to, the restrictions upon or the term of, an Option granted under this Article by cancellation of an outstanding Option and a subsequent regranting of an Option, by amendment, by substitution of an outstanding Option, by waiver or by other legally valid means. Such amendment or other action may provide for a greater or lesser number of shares subject to the Option, or provide for a longer or shorter vesting or exercise period. 3. NON-EMPLOYEE DIRECTOR OPTIONS. 3.1 Participation. ------------- Options under this Article 3 shall be made only to Non-Employee Directors and shall be evidenced by Option Agreements substantially in the form of Exhibit A hereto. 3.2 Annual Option Grants. -------------------- (a) Annual Options. On the first business day of each calendar year -------------- during the term of this Plan, commencing with the first business day occurring in 1998, there shall be granted automatically (without any action by the Committee or the Board) a Nonqualified Stock Option (the Option Date of which shall be such date) to each Non-Employee Director then in office to purchase 5,000 shares of Common Stock. (b) Maximum Number of Shares. Annual grants that would otherwise ------------------------ exceed the maximum number of shares under Section 1.4(a) shall be prorated within such limitation. A Non-Employee Director shall not receive more than one Nonqualified Stock Option under this Section 3.2 in any calendar year. 3.3 Option Price. ------------ The purchase price per share of the Common Stock covered by each Option granted pursuant to Section 3.2 hereof shall be 100 percent of the Fair Market Value of the Common Stock on the Option Date. The exercise price of any Option granted under this Article shall be paid in full at the time of each purchase in cash or by check or in shares of Common Stock valued at their Fair Market Value on the date of exercise of the Option, or partly in such shares and partly in cash, provided that any such ------------- 7

shares used in payment shall have been owned by the Participant at least six months prior to the date of exercise. 3.4 Option Period and Exercisability. -------------------------------- Each Option granted under this Article 3 and all rights or obligations thereunder shall expire ten years after the Option Date and shall be subject to earlier termination as provided below. Subject to section 3.5 below, each Option granted under Section 3.2 shall become exercisable on the first anniversary of the Option Date. 3.5 Termination of Directorship. --------------------------- If a Non-Employee Director's services as a member of the Board of Directors terminate for any reason other than Total Disability, death or retirement, any portion of an Option granted pursuant to this Article which is not then exercisable shall terminate and any portion of such Option which is then exercisable may be exercised for two years after the date of such termination or until the expiration of the stated term, whichever first occurs. If a Non-Employee Director's services as a member of the Board of Directors terminate because of Total Disability or death, then all Options granted pursuant to this Article shall become immediately exercisable and may be exercised for two years after the effective date of the termination of service or until the expiration of the stated term, whichever first occurs. If a Non- Employee Director retires on or after age 65 and after ten years of service as a Director, all Options granted pursuant to this Article shall become immediately exercisable and may be exercised for five years after the date of retirement or until the expiration of the stated term, whichever first occurs. 3.6 Adjustments. ----------- Options granted under this Article 3 shall be subject to adjustment as provided in Section 4.2, but only to the extent that (a) such adjustment and the Committee's actions in respect thereof satisfy the requirements of all applicable law, (b) such adjustment in the case of a Change in Control Event is effected pursuant to the terms of a reorganization agreement approved by shareholders of the Corporation, and (c) such adjustment is consistent with adjustments to Options held by persons other than executive officers or directors of the Corporation. 3.7 Acceleration Upon a Change in Control Event. ------------------------------------------- Upon the occurrence of a Change in Control Event, each Option granted under Section 3.2 hereof shall become immediately exercisable in full; provided, however, that none of the Options granted under Section 3.2 shall be accelerated to a date less than six months after the Award Date of such Option. To the extent that any Option granted under this Article 3 is not exercised prior to (i) a dissolution of the Corporation or (ii) a merger or other corporate event that the Corporation does not survive, and no provision is (or consistent with the provisions of Section 3.7 can be) made for the assumption, conversion, substitution or exchange of the Option, the Option shall terminate upon the occurrence of such event. 8

3.8 Limitation on Amendments. ------------------------ The provisions of this Article 3 shall not be amended more than once every six months (other than as may be necessary to conform to any applicable changes in the Code or the rules thereunder). 4. OTHER PROVISIONS. 4.1 Rights of Eligible Employees, Participants and Beneficiaries. ------------------------------------------------------------ (a) Employment Status. Status as an Eligible Employee shall not be ----------------- construed as a commitment that any Option will be made under this Plan to an Eligible Employee or to Eligible Employees generally. (b) No Employment Contract. Nothing contained in this Plan (or in any ---------------------- other documents related to this Plan or to any Option) shall confer upon any Eligible Employee or other Participant any right to continue in the employ or other service of the Company or constitute any contract or agreement of employment or other service, nor shall interfere in any way with the right of the Company to change such person's compensation or other benefits or to terminate the employment of such person, with or without cause, but nothing contained in this Plan or any document related hereto shall adversely affect any independent contractual right of such person without his or her consent thereto. (c) Plan Not Funded. Awards payable under this Plan shall be payable --------------- in shares or from the general assets of the Corporation, and (except as provided in Section 1.4(c)) no special or separate reserve, fund or deposit shall be made to assure payment of such Awards. No Participant, Beneficiary or other person shall have any right, title or interest in any fund or in any specific asset (including shares of Common Stock, except as expressly otherwise provided) of the Company by reason of any Option hereunder. Neither the provisions of this Plan (or of any related documents), nor the creation or adoption of this Plan, nor any action taken pursuant to the provisions of this Plan shall create, or be construed to create, a trust of any kind or a fiduciary relationship between the Company and any Participant, Beneficiary or other person. To the extent that a Participant, Beneficiary or other person acquires a right to receive payment pursuant to any Option hereunder, such right shall be no greater than the right of any unsecured general creditor of the Company. 4.2 Adjustments; Acceleration. ------------------------- (a) Adjustments. If there shall occur any extraordinary dividend or ----------- other extraordinary distribution in respect of the Common Stock (whether in the form of cash, Common Stock, other securities, or other property), or any recapitalization, stock split (including a stock split in the form of a stock dividend), reverse stock split, reorganization, merger, combination, 9

consolidation, split-up, spin-off, repurchase, or exchange of Common Stock or other securities of the Corporation, or there shall occur any other like corporate transaction or event in respect of the Common Stock or a sale of substantially all the assets of the Corporation as an entirety, then the Committee shall, in such manner and to such extent (if any) as it deems appropriate and equitable (i) proportionately adjust any or all of (a) the number and type of shares of Common Stock (or other securities) which thereafter may be made the subject of Options (including the specific numbers of shares set forth elsewhere in this Plan), (b) the number, amount and type of shares of Common Stock (or other securities or property) subject to any or all outstanding Options, (c) the exercise price of any or all outstanding Options, or (d) the securities, cash or other property deliverable upon exercise of any outstanding Options, or (ii) in the case of an extraordinary dividend or other distribution, merger, reorganization, consolidation, combination, sale of assets, split up, exchange, or spin off, make provision for a cash payment or for the substitution or exchange of any or all outstanding Options or the cash, securities or property deliverable to the holder of any or all outstanding Options based upon the distribution or consideration payable to holders of the Common Stock of the Corporation upon or in respect of such event; provided, however, in each case, that with respect to Incentive Stock -------- ------- Options, no such adjustment shall be made which would cause this Plan to violate Section 424(a) of the Code or any successor provisions thereto without the written consent of holders materially adversely affected thereby. In any of such events, the Committee may take such action sufficiently prior to such event if necessary to permit the Participant to realize the benefits intended to be conveyed with respect to the underlying shares in the same manner as is available to shareholders generally. (b) Acceleration of Options Upon Change in Control. As to any ---------------------------------------------- Participant who has been granted an Option pursuant to Article 2, unless prior to a Change in Control Event the Committee determines that, upon its occurrence, there shall be no acceleration of benefits under Options or determines that only certain or limited benefits under Options shall be accelerated and the extent to which they shall be accelerated, and/or establishes a different time in respect of such Change in Control Event for such acceleration, then upon the occurrence of a Change in Control Event each Option shall become immediately exercisable; provided, however, that in no event shall any Option be accelerated as to any Section 16 Person to a date less than six months after the Option Date of such Award. The Committee may override the limitations on acceleration in this Section 4.2(b) by express provision in the Option Agreement and may accord any Eligible Employee a right to refuse any acceleration, whether pursuant to the Option Agreement or otherwise, in such circumstances as the Committee may approve. Any acceleration of Options shall comply with applicable regulatory requirements, including without limitation Section 422 of the Code. 10

(c) Possible Early Termination of Accelerated Awards. If any Option ------------------------------------------------ under this Plan (other than an Option granted under Article 3) has been fully accelerated as permitted by Section 4.2(b) but is not exercised prior to (i) a dissolution of the Corporation, or (ii) a reorganization event described in Section 4.2(a) that the Corporation does not survive, or (iii) the consummation of reorganization event described in Section 4.2(a) that results in a Change in Control Event approved by the Board, and no provision has been made for the survival, substitution, exchange or other settlement of such Option, such Option shall thereupon terminate. 4.3 Effect of Termination of Employment. ----------------------------------- The Committee shall establish in respect of each Option granted to an Eligible Employee the effect of a termination of employment on the rights and benefits thereunder and in so doing may make distinctions based upon the cause of termination or otherwise. 4.4 Compliance with Laws. -------------------- This Plan, the granting and vesting of Options under this Plan and the issuance and delivery of shares of Common Stock and/or the payment of money under this Plan or under Options granted hereunder are subject to compliance with all applicable federal and state laws, rules and regulations (including but not limited to state and federal securities law and federal margin requirements) and to such approvals by any listing, regulatory or governmental authority as may, in the opinion of counsel for the Corporation, be necessary or advisable in connection therewith. Any securities delivered under this Plan shall be subject to such restrictions, and the person acquiring such securities shall, if requested by the Corporation, provide such assurances and representations to the Corporation as the Corporation may deem necessary or desirable to assure compliance with all applicable legal requirements. 4.5 Tax Withholding. --------------- (a) Cash or Shares. Upon any exercise of any Option or upon the -------------- disposition of shares of Common Stock acquired pursuant to the exercise of an Incentive Stock Option prior to satisfaction of the holding period requirements of Section 422 of the Code, the Company shall have the right at its option to (i) require the Participant (or Personal Representative or Beneficiary, as the case may be) to pay or provide for payment of the amount of any taxes which the Company may be required to withhold with respect to such Option event or payment or (ii) deduct from any amount payable in cash the amount of any taxes which the Company may be required to withhold with respect to such cash payment. In any case where a tax is required to be withheld in connection with the delivery of shares of Common Stock under this Plan, the Committee may in its sole discretion grant (either at the time of the Option or thereafter) to the Participant the right to elect, pursuant to such rules and subject to such 11

conditions as the Committee may establish, to have the Corporation reduce the number of shares to be delivered by (or otherwise reacquire) the appropriate number of shares valued at their then Fair Market Value, to satisfy such withholding obligation. (b) Tax Loans. The Company may, in its discretion, authorize a loan --------- to an Eligible Employee in the amount of any taxes which the Company may be required to withhold with respect to shares of Common Stock received (or disposed of, as the case may be) pursuant to a transaction described in subsection (a) above. Such a loan shall be for a term, at a rate of interest and pursuant to such other terms and conditions as the Company, under applicable law may establish. 4.6 Plan Amendment, Termination and Suspension. ------------------------------------------ (a) Board Authorization. The Board may, at any time, terminate or, ------------------- from time to time, amend, modify or suspend this Plan, in whole or in part. No Options may be granted during any suspension of this Plan or after termination of this Plan, but the Committee shall retain jurisdiction as to Options then outstanding in accordance with the terms of this Plan. (b) Shareholder Approval. Any amendment that would (i) materially -------------------- increase the benefits accruing to Participants under this Plan, (ii) materially increase the aggregate number of securities that may be issued under this Plan, or (iii) materially modify the requirements as to eligibility for participation in this Plan, shall be subject to shareholder approval only to the extent then required by Section 422 of the Code or applicable law, or deemed necessary or advisable by the Board. (c) Amendments to Options. Without limiting any other express --------------------- authority of the Committee under but subject to the express limits of this Plan, the Committee by agreement or resolution may waive conditions of or limitations on Options to Eligible Employees that the Committee in the prior exercise of its discretion has imposed, without the consent of a Participant, and may make other changes to the terms and conditions of Options that do not affect in any manner materially adverse to the Participant, his or her rights and benefits under an Option. Notwithstanding anything else contained herein to the contrary, the Committee shall not, without prior shareholder approval (i) authorize the amendment of outstanding Options to reduce the exercise price, as applicable, except as contemplated by Section 4.2, or (ii) cancel and replace outstanding Options with similar Options having an exercise or base price which is lower, except as contemplated by Section 4.2. (d) Limitations on Amendments to Plan and Options. No amendment, --------------------------------------------- suspension or termination of this Plan or change of or affecting any outstanding Option shall, without written consent of the 12

Participant, affect in any manner materially adverse to the Participant any rights or benefits of the Participant or obligations of the Corporation under any Option granted under this Plan prior to the effective date of such change. Changes contemplated by Section 4.2 shall not be deemed to constitute changes or amendments for purposes of this Section 4.6. 4.7 Privileges of Stock Ownership. ----------------------------- Except as otherwise expressly authorized by the Committee or this Plan, a Participant shall not be entitled to any privilege of stock ownership as to any shares of Common Stock not actually delivered to and held of record by him or her. No adjustment will be made for dividends or other rights as a shareholder for which a record date is prior to such date of delivery. 4.8 Effective Date of the Plan. -------------------------- This Plan shall be effective as of April 24, 1997, the date of Board approval, subject to shareholder approval within 12 months thereafter. 4.9 Term of the Plan. ---------------- No Option shall be granted more than ten years after the effective date of this Plan (the "Termination Date"). Unless otherwise expressly provided in this Plan or in an applicable Option Agreement, any Option theretofore granted may extend beyond such date, and all authority of the Committee with respect to Options hereunder shall continue during any suspension of this Plan and in respect of outstanding Options on such Termination Date. 4.10 Governing Law/Construction/Severability. --------------------------------------- (a) Choice of Law. This Plan, the Options, all documents evidencing ------------- Options and all other related documents shall be governed by, and construed in accordance with the laws of the State of California. (b) Severability. If any provision shall be held by a court of ------------ competent jurisdiction to be invalid and unenforceable, the remaining provisions of this Plan shall continue in effect. (c) Plan Construction. ----------------- (1) Rule 16b-3. It is the intent of the Corporation that ---------- transactions in and affecting Options in the case of Participants who are or may be subject to Section 16 of the Exchange Act satisfy any then applicable requirements of Rule 16b-3 so that such persons (unless they otherwise agree) will be entitled to the benefits of Rule 16b-3 or other exemptive rules under Section 16 of the Exchange Act in respect of these transactions and will not be subjected to avoidable liability thereunder. If any provision of this Plan or of any Option would otherwise frustrate or 13

conflict with the intent expressed above, that provision to the extent possible shall be interpreted so as to avoid such conflict. If the conflict remains irreconcilable, the Committee may disregard the provision if it concludes that to do so furthers the interest of the Corporation and is consistent with the purposes of this Plan as to such persons in the circumstances. (2) Section 162(m). It is the further intent of the Company that -------------- Options with an exercise price not less than Fair Market Value on the date of grant shall qualify as performance-based compensation under Section 162(m) of the Code, and this Plan shall be interpreted consistent with such intent. 4.11 Captions. -------- Captions and headings are given to the sections and subsections of this Plan solely as a convenience to facilitate reference. Such headings shall not be deemed in any way material or relevant to the construction or interpretation of this Plan or any provision thereof. 4.12 Effect of Change of Subsidiary Status. ------------------------------------- For purposes of this Plan and any Option hereunder, if an entity ceases to be a Subsidiary a termination of employment shall be deemed to have occurred with respect to each employee of such Subsidiary who does not continue as an employee of another entity within the Company. 4.13 Non-Exclusivity of Plan. ----------------------- Nothing in this Plan shall limit or be deemed to limit the authority of the Board or the Committee to grant awards or authorize any other compensation, with or without reference to the Common Stock, under any other plan or authority. 5.
