[LOGO] Itron PROXY STATEMENT This proxy statement is being furnished to shareholders of Itron, Inc. in connection with the solicitation by our Board of Directors of proxies for use at the Annual Meeting of Shareholders. The meeting will be held at the principal executive offices of Itron, Inc. (the Corporation), in the Atrium, at 2818 N. Sullivan Rd., Spokane, Washington, at 8:00 a.m., local time, on Friday, May 24, 2002, for the purposes listed in the accompanying Notice of Annual Meeting of Shareholders. We expect to mail this proxy statement and accompanying proxy to our shareholders on or about April 16, 2002. Matters to Be Considered at the Annual Meeting At the annual meeting, shareholders of record of Itron as of the close of business on March 29, 2002, will consider and vote on the following matters: (1) the election of four directors for a term of three years (until 2005), (2) the approval of an increase in the number of shares authorized under Itron's 2000 Stock Incentive Plan, (3) the approval of Itron's 2002 Employee Stock Purchase Plan, and (4) such other business that may properly come before the annual meeting and any adjournment or postponement of the annual meeting. Record Date and Outstanding Shares Holders of record of our common stock at the close of business on March 29, 2002, are entitled to notice of, and to vote at, the annual meeting. On the record date, there were 17,298,507 shares of our common stock outstanding. Each of our directors and executive officers plans to vote or direct the vote of all shares of common stock over which he or she has voting control in favor of the election of the nominees for director, the amendment to the 2000 Stock Incentive Plan and the approval of the 2002 Employee Stock Purchase Plan. Revocability of Proxies Shares represented at the annual meeting by properly signed proxies in the accompanying form will be voted at the annual meeting in accordance with the instructions given in the proxy. A shareholder may revoke a proxy given by the shareholder for use at the annual meeting at any time before the vote. A proxy may be revoked by: . submitting a later-dated proxy for the same shares at any time before the proxy is voted; . delivering written notice of revocation to the Corporate Secretary of Itron at any time before the vote; or . attending the annual meeting and voting in person. Mere attendance at the annual meeting will not revoke a proxy. If the annual meeting is postponed or adjourned for any reason, at any subsequent reconvening of the annual meeting, all proxies will be voted in the same manner as the proxies would have been voted at the original convening of the annual meeting (except for any proxies that have at that time effectively been revoked or withdrawn), even if the proxies had been effectively voted on the same or any other matter at a previous meeting. 1

Quorum and Voting Each shareholder will be entitled to one vote per share of common stock held on each matter to be voted on. The presence at the annual meeting, in person or represented by proxy, of holders of a majority of the outstanding common stock on the record date will constitute a quorum. Abstentions and broker nonvotes on any of the proposals to be voted on will be counted for purposes of determining the presence of a quorum. With respect to the election of directors, the nominees receiving the greatest number of votes duly cast will be elected as directors. Holders of common stock are not entitled to cumulative votes in the election of directors. Abstentions from voting on this matter will have no effect on its outcome because abstentions do not represent votes cast by shareholders in favor of any nominee. There will be no broker nonvotes on the election of directors because brokers who hold shares for the accounts of their clients have discretionary authority to vote such shares in this matter. The proposals to approve the 2002 Employee Stock Purchase Plan and the amendment of the Amended and Restated 2000 Stock Incentive Plan will be approved if the number of votes cast in favor of each proposal exceeds the number of votes cast against each proposal. Abstentions from voting and broker nonvotes on the plan proposals will not affect the outcome of either proposal because abstentions and broker nonvotes do not represent votes cast by shareholders either for or against the plan proposals. Proxy Solicitation Costs We have retained Georgeson Shareholder, 111 Commerce Road, Carlstadt, New Jersey, to aid in the solicitation of proxies. We will bear the cost of soliciting proxies, which we estimate will be approximately $5,000 plus expenses. Proxies may be solicited by personal interview, mail, telephone or facsimile. In addition, we may reimburse brokerage firms and other persons representing beneficial owners of our common stock for their expenses in forwarding solicitation materials to the beneficial owners. Our directors, officers and employees may also solicit proxies, without additional compensation, personally or by telephone. 2

ITEM 1 -- ELECTION OF DIRECTORS Our Board of Directors is divided into three classes, with each director generally holding office for a three-year term or until his or her successor has been elected and qualified.

Unless authority is withheld, the persons named as proxies in the accompanying proxy, will vote for the election of the nominees listed below.

Compensation of Directors Prior to May 2001, our nonemployee directors received an annual retainer of $12,000, 50% of which was paid with Itron common stock. Effective May 2001, the amount of the annual retainer was increased from $12,000 to $30,000 with $12,000 to be paid in cash and $18,000 to be paid with Itron common stock. With the increase in the annual retainer, our nonemployee directors will no longer receive $1,000 for each board and committee meeting attended after December 31, 2001. Our nonemployee directors receive stock options and stock grants under our amended and restated stock option grant program for nonemployee directors, which is administered under the terms and conditions of our 2000 Stock Incentive Plan. Beginning with this year's annual meeting, our nonemployee directors will automatically receive an option to purchase 10,000 shares of our common stock when they are initially appointed or elected to the Board, and an option to purchase 8,000 shares of our common stock immediately after each year's annual meeting. In addition, the chair of our committees and the chairman of the board will receive an option to purchase 1,250 shares of our common stock. The options are fully vested and exercisable on the date of 4

grant and have an exercise price equal to the fair market value of the common stock on the date of grant. Nonemployee directors also receive the common stock portion of their annual retainer under the terms of the program. Prior to May 2001, nonemployee directors were granted an option to purchase 4,000 shares per year and the chair of committees and the chairman of the board did not receive additional grants. Information on Committees of the Board of Directors and Meetings Our Board of Directors has established an Audit/Finance Committee, a Compensation Committee and a Nominating Committee. The Audit/Finance Committee reviews our accounting practices, internal accounting controls and financial results and oversees the engagement of our independent auditors. The Audit/Finance Committee members include Ted C. DeMerritt, Graham M. Wilson, and Jon E. Eliassen who serves as chairman. The Audit/Finance Committee held seven meetings during 2001. The Compensation Committee is responsible for setting compensation levels for our executive officers, overseeing the administration of various incentive compensation and benefit plans and performing any other functions regarding compensation that the board may delegate. The members of the Compensation Committee are Thomas S. Glanville, Mary Ann Peters, and Michael B. Bracy who serves as chairman. The Compensation Committee held five meetings during 2001. The Nominating Committee is responsible for soliciting recommendations for candidates for the Board of Directors, making recommendations to the board regarding such candidates, and reviewing and making recommendations to the board with respect to candidates for directors proposed by shareholders. The members of the Nominating Committee are Michael B. Bracy, Thomas S. Glanville, Mary Ann Peters, and Michael J. Chesser who serves as chairman. The Nominating Committee was formed in 2001 and held one meeting during 2001. There were seven board meetings in 2001. Each of the directors attended at least 75 percent of the meetings of the board and of each committee on which they were a member, except for Mary Ann Peters who attended five meetings of the board and three meetings of the Compensation Committee. ITEM 2 -- APPROVAL OF AMENDED AND RESTATED 2000 STOCK INCENTIVE PLAN Our Board of Directors has unanimously adopted an amendment to the 2000 Stock Incentive Plan that, subject to shareholder approval, authorizes an increase in the number of shares reserved for issuance from 1,825,000 shares to 4,025,000 shares. As of March 29, 2002, approximately 234,672 shares of common stock remained available for grant under the plan, and options to purchase approximately 17,298,507 shares of common stock were outstanding. The board believes that adding more shares to the 2000 Stock Incentive Plan will promote the interests of Itron and its shareholders by assisting us in attracting, retaining and stimulating the performance of individuals who make substantial contributions to our growth and success. The board further believes that stock ownership helps align employee interests with shareholder value creation. A copy of the 2000 Stock Incentive Plan, as amended and restated in its entirety to reflect the share increase, is attached to this proxy statement as Appendix A. The following description of the plan is a summary and does not purport to be fully descriptive. You should refer to Appendix A for more detailed information. 5

Description of the Amended and Restated 2000 Stock Incentive Plan Awards. The plan allows us to grant incentive and nonqualified stock options, shares of common stock or units denominated in common stock. Awards may consist of one or more of these grant types. Stock Subject to the Plan. A maximum of 4,025,000 shares of common stock are authorized for issuance under the plan. Prior to the board's approval of an increase in the number of shares reserved under the plan, 1,825,000 shares were authorized for issuance, which included a roll-in of 25,000 authorized but unissued shares from our 1989 Stock Option Plan. Under the plan, no more than 400,000 shares may be issued as stock awards (including restricted stock) or other stock-based awards other than stock options. In addition, no participant may receive more than 300,000 shares subject to awards in a single fiscal year, except that we can make additional one-time grants of up to 600,000 shares to newly hired individuals in any fiscal year, to the extent such limitations are required for compliance with Section 162(m) of the Internal Revenue Code of 1986, as amended (the Code). The previous limits are all adjusted automatically for stock splits and similar events. Any shares of common stock that have been made subject to an award that cease to be subject to the award (generally because the award terminates or expires) will be available for future grant under the plan. Administration. Our Compensation Committee administers the plan (the "plan administrator"), unless the board appoints another committee to administer the plan. Subject to the terms of the plan, the plan administrator selects the individuals to receive awards, determines the terms and conditions of all awards and interprets the provisions of the plan. Committee members administering the plan serve for such term as the board may determine, subject to removal by the board at any time. Eligible Participants. Awards may be granted to those officers, employees, consultants and independent contractors of Itron and our subsidiaries that the plan administrator selects. In consideration of services provided to the board, nonemployee directors receive stock awards and stock options in the form of automatic grants under the plan. These stock awards and stock option grants are described above under "Compensation of Directors." As of March 29, 2002, 1,092 individuals were eligible to participate in the plan. Stock Option Grants. Options granted under the plan may be incentive stock options (as defined in Section 422 of the Code) or nonqualified stock options. The exercise price for each option is determined by the plan administrator, but cannot be less than 100% of the common stock's fair market value on the date of grant with respect to incentive stock options (or 110% of fair market value in the case of a more than 10% shareholder). The option price may not be less than 85% of fair market value with respect to nonqualified stock options. For purposes of the plan, "fair market value" means the closing sales price for our common stock as reported by the Nasdaq Stock Market for a single trading day. As of March 29, 2002, the closing sales price of our common stock was $29.75 per share. The exercise price for shares purchased under options must be paid by cash or check, except that the plan administrator may authorize payment in any combination of cash or check, shares of already-owned common stock, a promissory note, a broker-assisted cashless exercise, or such other consideration as the plan administrator may permit. Unless the plan administrator determines otherwise, the term of each option is ten years from the date of grant, and the option vests at a rate of 25% per year over a four-year period. The plan administrator determines how long options will remain exercisable in the event an optionee ceases to provide services to us or one of our subsidiaries. Unless the plan administrator determines otherwise, options vested as of the date of termination by reason of death, disability or retirement generally will be exercisable for one year after the date of such termination and for three months after all other terminations. In the event an optionee is terminated for cause, the options terminate upon the participant's notification of such termination. 6

Transferability. Except as otherwise determined by the plan administrator and to the extent permitted by Section 422 of the Code, options and stock awards are not assignable or transferable by the participant other than by will or the laws of descent, except that a participant may designate a beneficiary who may exercise the award or receive payment under the award after the participant's death. During the participant's lifetime, awards may be exercised only by the participant. Adjustment of Shares. In the event of stock dividends, stock splits, spin-offs, or similar changes in our corporate or capital structure, the plan administrator, in its sole discretion, will make equitable adjustments in (a) the maximum number and kind of securities subject to the plan and the maximum number and kind of securities that may be made subject to awards to any participant, (b) the number and kind of securities that are subject to any outstanding award and the per share price of such securities, without any change in the aggregate price to be paid therefor, and (c) the number and kind of securities automatically granted pursuant to a formula program established under the plan. Corporate Transactions. If certain corporate transactions occur (such as a merger, consolidation, sale, lease, exchange or transfer of all or substantially all of our assets), a successor company or its parent will either assume all outstanding options or issue equivalent substitute options to purchase common stock of the successor company or its parent. Except for certain related party transactions (such as a reincorporation of Itron or a merger in which the shareholders immediately prior to the merger hold at least a majority of the shares in the successor company or its parent), all options assumed or replaced by the successor company will become fully vested and exercisable regardless of whether the vesting requirements have been satisfied. If the successor company does not assume or replace outstanding options, all outstanding options will become 100% vested and exercisable immediately prior to the corporate transaction. In such case, the right to exercise options terminates at the end of a specified time period, subject to completion of the corporate transaction. Termination and Amendment. The board may terminate or suspend the plan at any time. The board may also amend the plan, subject to shareholder approval in certain instances set forth in the plan. The plan does not have a fixed expiration date, except that no incentive stock options may be granted more than ten years after the later of (a) the plan's adoption by the board and (b) the adoption of any amendment to the plan that constitutes a new plan for purposes of Section 422 of the Code. Federal Income Tax Consequences. The following is a summary of the material United States federal income tax consequences to us and to participants in the plan. The summary is based on the Code and the United States Treasury regulations promulgated thereunder as in effect as of the date of the proxy statement, all of which may change with retroactive effect. The summary is not intended to be a complete analysis or discussion of all potential tax consequences that may be important to participants in the plan. Therefore, we strongly encourage participants to consult their own tax advisors as to the specific federal income tax or other tax consequences of their participation in the plan. Incentive Stock Options. The incentive stock options granted under the plan are intended to qualify for the favorable federal income tax treatment accorded "incentive stock options" under the Code. Generally, the grant or exercise of an incentive stock option does not result in any federal income tax consequences to the participant or to us. However, the exercise of an incentive stock option will generally increase the participant's alternative minimum tax liability, if any. The federal income tax consequences of a disposition of stock acquired through exercise of an incentive stock option will depend on the period such stock is held prior to disposition. If a participant holds stock acquired through exercise of an incentive stock option for at least two years from the date on which the option is granted and at least one year from the date of exercise of the option, the participant will recognize long-term capital gain or loss in the year of disposition, equal to the difference between the amount realized on the disposition of the stock and the amount paid for the stock on exercise of the option. 7

Generally, if the participant disposes of the stock before the expiration of either of the statutory holding periods described above (a "disqualifying disposition"), the participant will recognize ordinary income equal to the lesser of (i) the excess of the fair market value of the stock on the date of exercise over the exercise price and (ii) the excess of the amount realized on the disposition of the stock over the exercise price. Subject to certain limitations, to the extent the participant recognized ordinary income by reason of a disqualifying disposition, we generally will be entitled to a corresponding business expense deduction in the taxable year during which the disqualifying disposition occurs. Generally, in the taxable year of a disqualifying disposition, the participant will also recognize capital gain or loss equal to the difference between the amount realized on the disposition of such stock over the sum of the amount paid for such stock plus any amount recognized as ordinary income by reason of the disqualifying disposition. Such capital gain or loss will be characterized as short-term or long-term, depending upon how long the stock was held. Long-term capital gains generally are subject to lower tax rates than ordinary income and short-term capital gains. Currently, the maximum capital gains rate for federal income tax purposes is 20% while the maximum ordinary income rate is 38.6%. Slightly different rules may apply to optionees who acquire stock subject to certain repurchase options or who are subject to Section 16(b) of the Exchange Act. Nonqualified Stock Options. Generally, the grant of a nonqualified stock option will not result in any federal income tax consequences to the participant or to us. Upon exercise of a nonqualified stock option, the participant generally will recognize ordinary income equal to the excess of the fair market value of the stock on the date of exercise over the amount paid for the stock upon exercise of the option. Subject to certain limitations, we generally will be entitled to a corresponding business expense deduction equal to the ordinary income recognized by the participant. Upon disposition of the stock, the participant will recognize capital gain or loss equal to the difference between the amount realized on the disposition of such stock over the sum of the amount paid for such stock plus any amount recognized as ordinary income upon exercise of the option. Such capital gain or loss will be characterized as short-term or long term, depending upon how long the stock was held. Slightly different rules may apply to optionees who acquire stock subject to certain repurchase options or who are subject to Section 16(b) of the Exchange Act. Restricted stock and stock bonuses. Generally, upon acquisition of stock under a restricted stock or stock bonus award, the recipient will recognize ordinary income equal to the excess of the fair market value of the stock at the time of receipt over the amount, if any, paid for such stock. However, to the extent the stock is subject to certain restrictions, the recipient will not recognize ordinary income until the restrictions lapse or, if earlier, the time the stock becomes transferable. At such time, the recipient will recognize ordinary income equal to the excess of the current fair market value of the stock over the amount, if any, paid for the stock. Any further appreciation in the fair market value of the stock will be taxed upon disposition of the stock. Subject to certain limitations, we generally will be entitled to a corresponding business expense deduction equal to the ordinary income recognized by the recipient. However, within thirty (30) days of receipt of stock subject to restrictions as described above, the recipient may elect to recognize ordinary income in the taxable year of receipt, despite the fact that such stock is subject to restrictions. If such election is made, the recipient will recognize ordinary income equal to the excess of the fair market value of the stock at the time of receipt over the amount, if any, paid for the stock. Any further appreciation in the fair market value of the stock will be taxed upon the disposition of the stock. If the stock is later forfeited, the participant will not be allowed a deduction for any income recognized in connection with making the election. Upon disposition of the stock, the recipient will recognize capital gain or loss equal to the difference between the amount realized on the disposition of the stock and the sum of the amount paid for the stock, if any, plus any amount recognized as ordinary income upon acquisition or vesting of the stock (including income recognized pursuant to an election as described above). Such capital gain or loss will be characterized as short-term or long-term, depending upon how long the stock was held. 8

Slightly different rules may apply to persons who acquire stock subject to certain repurchase options or who are subject to Section 16(b) of the Exchange Act. Potential limitation on our deductions. Section 162(m) of the Code precludes a deduction for compensation paid to our chief executive officer and our four highest compensated officers (other than our chief executive officer) to the extent that such compensation exceeds $1,000,000 for a taxable year. If certain requirements are met, qualified performance-based compensation is disregarded for purposes of the $1,000,000 limitation. We believe that the plan has been structured in a manner that complies with Section 162(m) of the Code. Therefore, assuming certain requirements are met, payments made to such executive officers during the term of the plan generally will be deductible. Our Board of Directors recommends that you vote for approval of the Amended and Restated 2000 Stock Incentive Plan ITEM 3 -- APPROVAL OF 2002 EMPLOYEE STOCK PURCHASE PLAN Our board of directors unanimously adopted the 2002 Employee Stock Purchase Plan which, subject to shareholder approval, provides a means for our eligible employees and those of our subsidiaries to purchase shares of our common stock through payroll deductions. The 2002 Employee Stock Purchase Plan (the "ESPP") replaces our 1996 Stock Purchase Plan which no longer has any shares available for issuance and was suspended as of September 30, 2001. The board believes that the new ESPP will promote our interests and our shareholders' interests by assisting us in attracting, retaining, and stimulating the strong performance of employees, and by aligning employees' interests, through their purchases of our common stock, with the interests of shareholders. A copy of the ESPP is attached to this proxy statement as Appendix B. The following description of the ESPP is a summary and does not purport to be fully descriptive. You should refer to Appendix B for more detailed information. Description of the ESPP Purpose. Under the ESPP, qualified employees may purchase shares of common stock through payroll deductions at a discount from market price, without incurring broker commissions. The purpose of the ESPP is to assist our employees and those of our designated subsidiaries in acquiring a stock ownership interest in Itron pursuant to a plan that is intended to qualify for beneficial tax treatment under Section 423 of the Code. The ESPP is also intended to help employees provide for their future security, to support recruitment and retention of qualified employees and to provide employees with an advantageous means of accumulating long-term investments. Administration. Our Compensation Committee will administer the ESPP, unless the board appoints another committee to administer the ESPP (the "plan administrator"). The plan administrator is authorized to interpret the ESPP and to make such rules and regulations as it deems necessary to administer the ESPP, so long as such interpretation, administration or application regarding purchases under the ESPP corresponds with the requirements of Section 423 of the Code. 9

Stock Subject to the ESPP. The ESPP authorizes for issuance an aggregate of: . 70,000 shares of our common stock plus . an annual increase to be added as of the first day of our fiscal year beginning in 2003 equal to the least of (i) 50,000 shares or (ii) .5% of the outstanding shares of our common stock as of the end of our immediately preceding fiscal year on a fully diluted basis (assuming exercise of all outstanding options and warrants and conversion of all outstanding convertible preferred stock) and (iii) a lesser amount determined by our board; provided, however, that any shares from any increase in previous years that are not actually issued will continue to be available for issuance under the ESPP. Eligibility. To be eligible to participate in the ESPP, an employee must normally work at least 20 hours per week and a minimum of five months per calendar year. The plan administrator may change the eligibility criteria for participation in the ESPP for future offering periods within the limits of Section 423 of the Code. Nonemployee directors and employees who own 5% or more of our common stock are not eligible to participate in the ESPP. Approximately 1,086 employees are eligible to participate in the ESPP. Offering Periods. The ESPP is divided into four three-month offering periods that begin on January 1, April 1, July 1 and October 1 of each year. During these periods, participants accumulate funds in an account used to buy common stock through payroll deductions at a rate of not less than 1% and not more than 10% of such employee's compensation during each payroll period in the offering period. At the end of each three-month offering period, the employees' accumulated funds are used to purchase the appropriate number of whole shares of common stock. No employee may purchase more than $25,000 worth of common stock (based on the fair market value of the common stock on the first day of an offering period) during any calendar year under the ESPP or more than 250 shares of common stock in any offering period. Purchase Price. The purchase price per share of common stock acquired under the ESPP is 85% of the lesser of (1) the fair market value of the common stock on the first business day of an offering period and (2) the fair market value of the common stock on the last business day of an offering period. For purposes of the ESPP, "fair market value" means the closing sales price for our common stock as reported by the Nasdaq Stock Market for a single trading date. As of March 29, 2002, the closing sales price of our common stock was $29.75 per share. Effect of Termination. Employees have no right to acquire shares under the ESPP upon termination of their employment for any reason prior to the last business day of an offering period. Upon termination of employment, we will pay the balance in the employee's account to the employee or to his or her estate without interest. Neither payroll deductions credited to an employee's account nor any rights with regard to the purchase of shares under the ESPP may be assigned, transferred, pledged or otherwise disposed of in any way by the employee, other than by will or the laws of descent and distribution. Change in Control. If certain corporate transactions occur (such as a merger, consolidation or acquisition by another corporation of all or substantially all of our assets), each outstanding option to purchase shares under the ESPP will be assumed or an equivalent option substituted by a successor company or its parent. If the successor company refuses to assume or substitute for the option, the offering period during which a participant may purchase stock will be shortened to a specified date before the proposed transaction. In the event of a proposed liquidation or dissolution of Itron, the offering period during which a participant may purchase stock will be shortened to a specified date before the date of the proposed liquidation or dissolution. Amendment, Suspension and Termination of the ESPP. The board has the power to amend, suspend or terminate the ESPP, except that the board may not amend the ESPP without shareholder approval if such approval is required by Section 423 of the Code. Unless sooner terminated, the ESPP will terminate on May 24, 2012. 10

Federal Income Tax Consequences The following is a summary of the material United States federal income tax consequences to us and to participants in the ESPP. The summary is based on the Code and the United States Treasury regulations promulgated thereunder as in effect as of the date of the proxy statement, all of which may change with retroactive effect. The summary is not intended to be a complete analysis or discussion of all potential tax consequences that may be important to participants in the ESPP. Therefore, we strongly encourage participants to consult their own tax advisors as to the specific federal income tax or other tax consequences of their participation in the ESPP. Under the Code, we are deemed to grant employee participants in the ESPP an "option" on the first day of each offering period to purchase as many shares of common stock as the employee will be able to purchase with the payroll deductions credited to his or her account during the offering period. On the last day of each three-month offering period, the purchase price is determined and the employee is deemed to have exercised the "option" and purchased the number of shares of common stock his or her accumulated payroll deductions will purchase at the purchase price. The required holding period for favorable federal income tax treatment upon disposition of common stock acquired under the ESPP is the later of (1) two years after the deemed "option" is granted (the first day of an offering period) and (2) one year after the deemed "option" is exercised and the common stock is purchased (the last day of an offering period). When the common stock is disposed of after this period (a "qualifying disposition"), the employee realizes ordinary income to the extent of the lesser of (a) the amount by which the fair market value of the common stock at the time the deemed "option" was granted exceeded the "option price" and (b) the amount by which the fair market value of the common stock at the time of the disposition exceeded the "option price." The "option price" is equal to 85% of the lesser of the fair market value of the common stock on the first day of the offering period and the fair market value of the common stock on the last day of the offering period. Thus, the maximum amount of gain taxable as ordinary income is the amount of the 15% discount measured as of the last day of an offering period. Any further gain recognized on a qualifying disposition will be long-term capital gain. If the sale price is less than the option price, there is no ordinary income and any loss recognized generally will be a long-term capital loss. When an employee sells the common stock before the expiration of the required holding period (a "disqualifying disposition"), the employee recognizes ordinary income to the extent of the difference between the price actually paid for the common stock and the fair market value of the common stock at the date the option was exercised (the last day of an offering period), regardless of the price at which the common stock is sold. Any additional gain recognized upon the disqualifying disposition will be capital gain. The capital gain will be long-term if the employee held the shares more than 12 months. If the sale price is less than the fair market value of the common stock at the date of exercise, then the employee will have a capital loss equal to such difference. Even though an employee must treat part of his or her gain on a qualifying disposition of the common stock as ordinary income, we may not take a business deduction for such amount. However, if an employee makes a disqualifying disposition, the amount of income that the employee must report as ordinary income qualifies as a business deduction for us for the year of such disposition. Our Board of Directors recommends a vote for approval of the 2002 Employee Stock Purchase Plan. 11

Change of Control Agreements We have entered into change of control agreements with our executive officers to provide compensation and benefits in the event of a change of control of Itron. Under these agreements, our executive officers have agreed to remain employed by Itron on an annual basis and are compensated by an annual salary and bonus as determined by the Compensation Committee of our Board of Directors. If we terminate the employment 13

relationship other than for cause or if the executive officer terminates his or her employment for good reason within a specified period following a change of control, (the "Change of Control Period," which is three years for Mr. Nosbaum, Mr. Neilson, Mr. Remington and Mr. Fairbanks, two years for Mr. Gelvin and is two years or one year for other executive officers), the executive officer will receive any salary or bonus due to the executive officer, group insurance benefits and severance pay equal to the executive's annual base salary and bonus for the fiscal year in which the termination occurs, multiplied by the Change of Control Period. Severance amounts are partially offset if the executive officer realizes a benefit from the acceleration of stock options in connection with the change of control. The executive officer will also receive a bonus equal to his or her annual salary plus annual bonus if his or her employment continues for a full one-year period following a change of control. Employment Agreements David G. Remington, our vice president and chief financial officer since February 1996, is party to an employment agreement with us. This agreement provides for an initial base salary of $250,000, which may be increased annually by our chief executive officer, subject to the approval of the Compensation Committee. The agreement also provides for annual incentive bonus payments to the extent they are earned in accordance with the Corporation's executive incentive compensation plan. Either party under certain conditions may terminate the agreement. If we terminate the agreement other than for cause, we are required to pay Mr. Remington an amount equal to his then-current annual base salary. Under the agreement, we granted Mr. Remington options to purchase 45,000 shares of our common stock at the fair market value of our common stock on the date of the grant. These options are now fully vested. Compensation Committee Report on Executive Compensation The Compensation Committee of our Board of Directors (the "Committee") annually reviews and recommends to the full board the compensation levels for our executive officers. The Committee is comprised of board members who are not employees of Itron. The Committee's primary objective in establishing compensation opportunities for our executive officers is to support our goal of maximizing the value of our shareholders' interests in Itron. To achieve this objective, the Committee believes it is critical to: . Pay competitively to attract, retain and motivate a highly competent executive team; . Provide incentive opportunities that link corporate performance and executive pay and pay executives competitive levels of incentive compensation when corporate financial and other performance expectations are achieved; and . Align executives' financial interests with the creation of shareholder value by providing long-term incentives in the form of options to acquire common stock and performance-based restricted stock. The Committee makes recommendations to the board regarding our executive compensation plans, which promote the objectives detailed above. The Committee periodically engages outside consultants to determine approximate compensation levels among executives in comparable jobs in comparable high-tech companies. The Committee believes that our current compensation plans support our business mission and contribute to our financial success. Section 162(m) of the Internal Revenue Code limits the tax deduction available to public companies for compensation paid to individual executive officers to $1 million in any taxable year, unless certain performance, disclosure and shareholder approval requirements are met. Under Section 162(m), however, compensation above $1 million may be deducted if it is "performance-based compensation" within the meaning of the Code. When consistent with our compensation philosophy, the Committee intends to structure our compensation program so that compensation expense is deductible by Itron for tax purposes. 14

Base Salary The Committee annually reviews each executive officer's base salary. The factors that the Committee considers in making recommendations regarding base salary include levels of pay among executives in similar jobs within similar high-tech companies, level of responsibility, prior experience, breadth of knowledge, as well as Corporation performance and job performance. The Committee targets base salaries at the 50th percentile of the market and at approximately the 75th percentile for annual and long-term incentive compensation. The market is defined as similar high-tech companies, nationwide, the annual revenues of which are approximately $250 million and that have similar executive-level jobs, which the Committee believes is a highly competitive job market. These companies are not necessarily the same as the companies included in our peer reference group used in the performance graph. In general, for 2001, base salaries for the executive officers are near the 50th percentile of the market. With respect to the chief executive officer's compensation, the Committee increased Mr. Nosbaum's base salary to $400,000 on October 1, 2000 in light of the Corporation's significantly improved financial performance and progress toward long-term goals achieved under Mr. Nosbaum's stewardship. The Committee believes that it is important that Mr. Nosbaum's base salary be competitive with those of other chief executive officers with similar responsibilities and broad leadership experience in the market defined. The Committee recognizes and highly values Mr. Nosbaum's visionary leadership, breadth of knowledge, business and utility experience, and highly values his contributions to the Corporation since becoming CEO. Executive Incentive Compensation Plan ("EIC Plan") The EIC Plan provides the opportunity for our executive officers to earn both annual and long-term incentives in addition to their base salaries. The Committee believes that having as much as or more than 50% of an executive officer's total compensation at risk fosters achievement of our short-term and long-term financial performance goals. Annual Incentives: Each year, the Compensation Committee establishes annual financial and other goals that relate to one or more indicators of corporate performance and targets amounts as a specified percentage of the executive officer's salary. For 2001, these percentages ranged from 42% to 80% of base salary. Incentive awards, which are made in cash, are paid to participating executives under the EIC Plan only when the established financial and other goals are achieved. For 2001, depending on the extent to which corporate goals were achieved, an executive officer was entitled to receive from zero to 200% of the targeted award. Targets are established for the chief executive officer in the same manner as for other officers. For 2001, the annual incentive award opportunity was contingent upon attaining established levels of net profit after tax along with other strategic goals. The average achievement level for all executive officers combined in 2001 was 124%. Annual incentive payments earned in 2001 were paid in February 2002 and are included in the Summary Compensation Table under the column entitled "Bonus." Long-Term Incentives: In 2001, our long-term incentives consisted of stock options. The number of stock options granted is determined by the recipient's position and amount of options currently held, and is intended to recognize different levels of responsibility. All options are granted with an option exercise price equal to the fair market value of our common stock on the date of grant. This closely links a significant portion of executive compensation to benefits produced for all shareholders. The Committee approved normal stock option grants for key employees, including executive officers, based on the above criteria during its regular meetings in 2001. Michael B. Bracy, Chairman Thomas S. Glanville Mary Ann Peters 15

Audit/Finance Committee Report The Audit/Finance Committee is composed of independent directors as defined by Rule 4200(a)(14) of the National Association of Securities Dealers rules and acts under a written charter developed by the Committee in 2000. Management is responsible for the Corporation's internal controls and the financial reporting process. Deloitte & Touche LLP, the Corporation's independent auditors, is responsible for performing an independent audit of the Corporation's consolidated financial statements in accordance with auditing standards generally accepted in the United States of America, and for issuing a report thereon. The Committee's responsibility is to monitor and oversee these processes on behalf of the Board of Directors. In connection with the December 31, 2001 financial statements, the Audit/Finance Committee (1) reviewed and discussed the audited financial statements with management; (2) discussed with the auditors the matters required by Statement on Auditing Standards No. 61; and (3) received the written disclosures and the letter from the auditors required by Independence Standards Board Statement No. 1 and discussed with the auditors the auditor's independence. Based upon these reviews and discussions, the Audit/Finance Committee has recommended to the Board of Directors, and the Board of Directors has approved, that the Corporation's audited financial statements be included in the Securities and Exchange Commission Annual Report on Form 10-K for the fiscal year ended December 31, 2001. Audit Fees: The aggregate fees billed by Deloitte & Touche LLP, the member firms of Deloitte Touche Tohmatsu, and their respective affiliates (collectively, "Deloitte & Touche") for professional services rendered for the audit of the Company's annual financial statements for the fiscal year ended December 31, 2001, responses to SEC comment letters related to certain of the Company's 1934 Act filings and for the reviews of the financial statements included in the Corporation's Quarterly Reports on Form 10-Q for that fiscal year were $432,300. Financial Information Systems Design and Implementation Fees: The aggregate fees billed by Deloitte & Touche for professional services rendered for information technology services relating to financial information systems design and implementation for the fiscal year ended December 31, 2001, were $113,400. All Other Fees: The aggregate fees billed by Deloitte & Touche for services rendered to the Corporation, other than the services described above under "Audit Fees" and "Financial Information Systems Design and Implementation Fees," for the fiscal year ended December 31, 2001, were $281,100, including audit related services of approximately $81,000 and non-audit services of $200,100. Audit related services generally include fees for due diligence and related services on acquisitions, royalty audits, accounting consultations and work on SEC filings. The non-audit related services consist primarily of tax consulting. The Audit/Finance Committee has considered whether the non-audit services provided to the Corporation by Deloitte & Touche are compatible with maintaining the auditor's independence. Jon E.

SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE Section 16(a) of the Securities Exchange Act of 1934 requires our officers and directors, and persons who own more than 10% of a registered class of our equity securities, to file reports of ownership and changes in ownership with the Securities and Exchange Commission. SEC regulations require our officers, directors and greater-than-10% shareholders to provide us with copies of all Section 16(a) forms they file. Based solely on our review of the copies of these forms we have received, or written representations from reporting persons that no such forms were required for those persons, we believe that during 2001 all of our officers, directors and greater-than-10% beneficial owners complied with all applicable filing requirements. SECURITY OWNERSHIP OF PRINCIPAL SHAREHOLDERS AND MANAGEMENT The following table provides information with respect to the beneficial ownership of our common stock as of February 28, 2002 by: . each of our directors; . each of our executive officers for whom compensation is reported in this proxy statement; . each person that we know beneficially owns more than 5% of our common stock; and . all of our directors and executive officers as of February 28, 2002 as a group. The percentage ownership data is based on 16,344,662 shares of our common stock outstanding as of February 28, 2002. Under SEC rules, beneficial ownership includes shares over which the indicated beneficial owner exercises voting and/or investment power. Shares of common stock subject to options that are currently exercisable or will become exercisable within 60 days are deemed outstanding for computing the number of shares and the percentage ownership of the person holding the option, but are not deemed outstanding for purposes of computing the percentage ownership of any other person. Except as otherwise noted, we believe that the beneficial owners of the shares of common stock listed below have sole voting and investment power with respect to all shares beneficially owned, subject to applicable community property laws.

RELATED-PARTY TRANSACTIONS In July 1995, we purchased our principal office and manufacturing facilities in Spokane, Washington, from Pentzer Development Corporation, a subsidiary of Avista Corporation, for $8 million. A member of our Board of Directors is an officer of Avista Corporation. In connection with the purchase, we borrowed $5.6 million from Avista under a long-term note agreement requiring monthly payments of principal and interest, at a rate of 9% per annum through August 2015. In January 2002, we paid $4.9 million, which represents a $200,000 discount, to Avista to fully satisfy our mortgage note. In March 2001, Itron loaned $750,000 to its chairman of the board, S. Edward White, to facilitate Mr. White's continued ownership of our common stock. In connection with the loan, Mr. White executed a promissory note in favor of Itron in the amount of $750,000, and secured the note by a pledge of 300,000 of Mr. White's shares of Itron common stock. The balance of the secured promissory note, including principal and interest, was paid in full by the end of 2001. Rob Neilson's wife was employed by us during the fiscal year 2001 at an annual salary of $190,000.

Awards may be granted singly or in combination. 6.2 Settlement of Awards The Company may settle Awards through the delivery of shares of Common Stock, the granting of replacement Awards or any combination thereof as the Plan Administrator shall determine. Any Award settlement, including payment deferrals, may be subject to such conditions, restrictions and contingencies as the Plan Administrator shall determine. The Plan Administrator may permit or require the deferral of any Award payment, subject to such rules and procedures as it may establish, which may include provisions for the payment or crediting of interest, or dividend equivalents, including converting such credits into deferred stock equivalents. 6.3 Acquired Company Awards Notwithstanding anything in the Plan to the contrary, the Plan Administrator may grant Awards under the Plan in substitution for awards issued under other plans, or assume under the Plan awards issued under other plans, if the other plans are or were plans of other acquired entities ("Acquired Entities") (or the parent of the Acquired Entity) and the new Award is substituted, or the old award is assumed, by reason of a merger, consolidation, acquisition of property or stock, reorganization or liquidation (the "Acquisition Transaction"). In the event that a written agreement pursuant to which the Acquisition Transaction is completed is approved by the Board and said agreement sets forth the terms and conditions of the substitution for or assumption of outstanding awards of the Acquired Entity, said terms and conditions shall be deemed to be the action of the Plan Administrator without any further action by the Plan Administrator, except as may be required for compliance with Rule 16b-3 under the Exchange Act, and the persons holding such awards shall be deemed to be Participants. SECTION 7. AWARDS OF OPTIONS 7.1 Grant of Options The Plan Administrator is authorized under the Plan, in its sole discretion, to issue Options as Incentive Stock Options or as Nonqualified Stock Options, which shall be appropriately designated. 7.2 Option Exercise Price The exercise price for shares purchased under an Option shall be as determined by the Plan Administrator, but shall not be less than 100% of the Fair Market Value of the Common Stock on the Grant Date with respect to Incentive Stock Options and not less than 85% of the Fair Market Value of the Common Stock on the Grant Date with respect to Nonqualified Stock Options. For Incentive Stock Options granted to a more than 10% shareholder, the Option exercise price shall be as specified in Section 8.2. 7.3 Term of Options The term of each Option (the "Option Term") shall be as established by the Plan Administrator or, if not so established, shall be ten years from the Grant Date. For Incentive Stock Options, the maximum Option Term shall be as specified in Sections 8.2 and 8.4. A-4

7.4 Exercise of Options The Plan Administrator shall establish and set forth in each instrument that evidences an Option the time at which, or the installments in which, the Option shall vest and become exercisable, which provisions may be waived or modified by the Plan Administrator at any time. If not so established in the instrument evidencing the Option, the Option shall vest and become exercisable according to the following schedule, which may be waived or modified by the Plan Administrator at any time: Period of Participant's Continuous Employment or Service With the Company or Its Related Percent of Total Option Corporations From the That Is Vested and Vesting Base Date Exercisable ----------------- ------------------------- After 1 year 25% After 2 years 50% After 3 years 75% After 4 years 100% The Plan Administrator may adjust the vesting schedule of an Option held by a Participant who works less than "full-time" as that term is defined by the Plan Administrator or who takes a Company-approved leave of absence. To the extent that an Option has vested and become exercisable, the Option may be exercised from time to time by delivery to the Company of a written stock option exercise agreement or notice, in a form and in accordance with procedures established by the Plan Administrator, setting forth the number of shares with respect to which the Option is being exercised, the restrictions imposed on the shares purchased under such exercise agreement, if any, and such representations and agreements as may be required by the Plan Administrator, accompanied by payment in full as described in Section 7.5. An Option may not be exercised for less than a reasonable number of shares at any one time, as determined by the Plan Administrator. 7.5 Payment of Exercise Price The exercise price for shares purchased under an Option shall be paid in full to the Company by delivery of consideration equal to the product of the Option exercise price and the number of shares purchased. Such consideration must be paid in cash or by check or, unless the Plan Administrator in its sole discretion determines otherwise, either at the time the Option is granted or at any time before it is exercised, in any combination of (a) cash or check; (b) tendering (either actually or, if and so long as the Common Stock is registered under Section 12(b) or 12(g) of the Exchange Act, by attestation) shares of Common Stock already owned by the Participant for at least six months (or any shorter period necessary to avoid a charge to the Company's earnings for financial reporting purposes) having a Fair Market Value on the day prior to the exercise date equal to the aggregate Option exercise price; (c) if and so long as the Common Stock is registered under Section 12(b) or 12(g) of the Exchange Act, delivery of a properly executed exercise notice, together with irrevocable instructions, to (i) a brokerage firm designated by the Company to deliver promptly to the Company the aggregate amount of sale or loan proceeds to pay the Option exercise price and any withholding tax obligations that may arise in connection with the exercise and (ii) the Company to deliver the certificates for such purchased shares directly to such brokerage firm, all in accordance with the regulations of the Federal Reserve Board; or (d) such other consideration as the Plan Administrator may permit. In addition, to assist a Participant (including a Participant who is an officer or a director of the Company) in acquiring shares of Common Stock pursuant to an Award granted under the Plan, the Plan Administrator, in its sole discretion, may authorize, either at the Grant Date or at any time before the acquisition of Common Stock pursuant to the Award, (i) the payment by a Participant of a promissory note or (ii) the guarantee by the A-5

Company of a loan obtained by the Participant from a third party; provided, however, that any such note or loan must be full-recourse to the extent necessary to avoid charges to the Company's earnings for financial reporting purposes. Subject to the foregoing, the Plan Administrator shall in its sole discretion specify the terms of any loans or loan guarantees, including the interest rate and terms of and security for repayment. 7.6 Post-Termination Exercises The Plan Administrator shall establish and set forth in each instrument that evidences an Option whether the Option shall continue to be exercisable, and the terms and conditions of such exercise, if a Participant ceases to be employed by, or to provide services to, the Company or its Related Corporations, which provisions may be waived or modified by the Plan Administrator at any time. If not so established in the instrument evidencing the Option, the Option shall be exercisable according to the following terms and conditions, which may be waived or modified by the Plan Administrator at any time: (a) Any portion of an Option that is not vested and exercisable on the date of termination of the Participant's employment or service relationship (the "Termination Date") shall expire on such date. (b) Any portion of an Option that is vested and exercisable on the Termination Date shall expire upon the earliest to occur of: (i) the last day of the Option Term; (ii) if the Participant's Termination Date occurs for reasons other than Cause, Retirement, Death or Disability, the three-month anniversary of such Termination Date; and (iii) if the Participant's Termination Date occurs by reason of Retirement, Disability or death, the one-year anniversary of such Termination Date. Notwithstanding the foregoing, if the Participant dies after the Termination Date while the Option is otherwise exercisable, the portion of the Option that is vested and exercisable on such Termination Date shall expire upon the earlier to occur of (y) the last day of the Option Term and (z) the first anniversary of the date of death, unless the Plan Administrator determines otherwise. Also notwithstanding the foregoing, in case of termination of the Participant's employment or service relationship for Cause, the Option shall automatically expire upon first notification to the Participant of such termination, unless the Plan Administrator determines otherwise. If a Participant's employment or service relationship with the Company is suspended pending an investigation of whether the Participant shall be terminated for Cause, all the Participant's rights under any Option likewise shall be suspended during the period of investigation. If any facts that would constitute termination for Cause are discovered after a Participant's Termination Date, any Option then held by the Participant may be immediately terminated by the Plan Administrator, in its sole discretion. A Participant's transfer of employment or service relationship between or among the Company and its Related Corporations, or a change in status from an employee to a consultant, agent, advisor or independent contractor or vice versa, shall not be considered a termination of employment or service relationship for purposes of this Section 7. The effect of a Company-approved leave of absence on the terms and conditions of an Option shall be determined by the Plan Administrator, in its sole discretion. A-6

SECTION 8. INCENTIVE STOCK OPTION LIMITATIONS To the extent required by Section 422 of the Code, Incentive Stock Options shall be subject to the following additional terms and conditions: 8.1 Dollar Limitation To the extent the aggregate Fair Market Value (determined as of the Grant Date) of Common Stock with respect to which Incentive Stock Options are exercisable for the first time during any calendar year (under the Plan and all other stock option plans of the Company) exceeds $100,000, such portion in excess of $100,000 shall be treated as a Nonqualified Stock Option. In the event the Participant holds two or more such Options that become exercisable for the first time in the same calendar year, such limitation shall be applied on the basis of the order in which such Options are granted. 8.2 More Than 10% Stockholders If an individual owns more than 10% of the total combined voting power of all classes of the stock of the Company or of its parent or subsidiary corporations, then the exercise price per share of an Incentive Stock Option shall not be less than 110% of the Fair Market Value of the Common Stock on the Grant Date and the Option Term shall not exceed five years. The determination of more than 10% ownership shall be made in accordance with Section 422 of the Code. 8.3 Eligible Employees Individuals who are not employees of the Company or one of its parent corporations or subsidiary corporations may not be granted Incentive Stock Options. 8.4 Term Subject to Section 8.2, the Option Term shall not exceed ten years. 8.5 Exercisability An Option designated as an Incentive Stock Option shall cease to qualify for favorable tax treatment as an Incentive Stock Option to the extent it is exercised (if permitted by the terms of the Option) (a) more than three months after the Termination Date for reasons other than death or Disability, (b) more than one year after the Termination Date by reason of Disability, or (c) after the Participant has been on leave of absence for more than 90 days, unless the Participant's reemployment rights are guaranteed by statute or contract. 8.6 Taxation of Incentive Stock Options In order to obtain certain tax benefits afforded to Incentive Stock Options under Section 422 of the Code, the Participant must hold the shares issued upon the exercise of an Incentive Stock Option for two years after the Grant Date and one year from the date of exercise. A Participant may be subject to the alternative minimum tax at the time of exercise of an Incentive Stock Option. The Participant shall give the Company prompt notice of any disposition of shares acquired by the exercise of an Incentive Stock Option prior to the expiration of such holding periods. 8.7 Promissory Notes The amount of any promissory note delivered pursuant to Section 7.5 in connection with an Incentive Stock Option shall bear interest at a rate specified by the Plan Administrator, but in no case less than the rate required to avoid imputation of interest (taking into account any exceptions to the imputed interest rules) for federal income tax purposes. A-7

8.8 Code Definitions For purposes of this Section 8, "parent corporation" and "subsidiary corporation" shall have the meanings attributed to those terms for purposes of Section 422 of the Code. SECTION 9. STOCK AWARDS 9.1 Grant of Stock Awards The Plan Administrator is authorized to make Awards of Common Stock or Awards denominated in units of Common Stock on such terms and conditions and subject to such restrictions, if any (which may be based on continuous service with the Company or the achievement of performance goals related to profits, profit growth, profit-related return ratios, cash flow or total shareholder return, where such goals may be stated in absolute terms or relative to comparison companies), as the Plan Administrator shall determine, in its sole discretion, which terms, conditions and restrictions shall be set forth in the instrument evidencing the Award. The terms, conditions and restrictions that the Plan Administrator shall have the power to determine shall include, without limitation, the manner in which shares subject to Stock Awards are held during the periods they are subject to restrictions and the circumstances under which forfeiture of the Stock Award shall occur by reason of termination of the Participant's employment or service relationship. 9.2 Issuance of Shares Upon the satisfaction of any terms, conditions and restrictions prescribed in respect to a Stock Award, or upon the Participant's release from any terms, conditions and restrictions of a Stock Award, as determined by the Plan Administrator, the Company shall release, as soon as practicable, to the Participant or, in the case of the Participant's death, to the personal representative of the Participant's estate or as the appropriate court directs, the appropriate number of shares of Common Stock. 9.3 Waiver of Restrictions Notwithstanding any other provisions of the Plan, the Plan Administrator may, in its sole discretion, waive the forfeiture period and any other terms, conditions or restrictions on any Stock Award under such circumstances and subject to such terms and conditions as the Plan Administrator shall deem appropriate; provided, however, that the Plan Administrator may not adjust performance goals for any Stock Award intended to be exempt under Section 162(m) of the Code for the year in which the Stock Award is settled in such a manner as would increase the amount of compensation otherwise payable to a Participant. SECTION 10. WITHHOLDING The Company may require the Participant to pay to the Company the amount of any withholding taxes that the Company is required to withhold with respect to the grant, vesting or exercise of any Award. Subject to the Plan and applicable law, the Plan Administrator may, in its sole discretion, permit the Participant to satisfy withholding obligations, in whole or in part, (a) by paying cash, (b) by electing to have the Company withhold shares of Common Stock (up to the minimum required federal tax withholding rate) or (c) by transferring to the Company shares of Common Stock (already owned by the Participant for the period necessary to avoid a charge to the Company's earnings for financial reporting purposes), in such amounts as are equivalent to the Fair Market Value of the withholding obligation. SECTION 11. ASSIGNABILITY Awards granted under the Plan and any interest therein may not be assigned, pledged or transferred by the Participant and may not be made subject to attachment or similar proceedings otherwise than by will or by the applicable laws of descent and distribution, except to the extent a Participant designates a beneficiary on a Company-approved form who may exercise the Award or receive payment under the Award after the A-8

Participant's death. During a Participant's lifetime, Awards may be exercised only by the Participant. Notwithstanding the foregoing, and to the extent permitted by Section 422 of the Code, the Plan Administrator, in its sole discretion, may permit such assignment or transfer; provided, however, that any Award so assigned or transferred shall be subject to all the same terms and conditions contained in the instrument evidencing the Award. SECTION 12. ADJUSTMENTS 12.1 Adjustment of Shares In the event that, at any time or from time to time, a stock dividend, stock split, spin-off, combination or exchange of shares, recapitalization, merger, consolidation, distribution to stockholders other than a normal cash dividend, or other change in the Company's corporate or capital structure results in (a) the outstanding shares, or any securities exchanged therefor or received in their place, being exchanged for a different number or class of securities of the Company or of any other corporation or (b) new, different or additional securities of the Company or of any other corporation being received by the holders of shares of Common Stock of the Company, then the Plan Administrator shall make proportional adjustments in (i) the maximum number and kind of securities subject to the Plan as set forth in Section 4.1 and the maximum number and kind of securities that may be made subject to Stock Awards and to Awards to any individual as set forth in Section 4.2, (ii) the number and kind of securities that are subject to any outstanding Award and the per share price of such securities, without any change in the aggregate price to be paid therefor, and (iii) and the number and kind of securities automatically granted pursuant to a formula program established under the Plan. The determination by the Plan Administrator as to the terms of any of the foregoing adjustments shall be conclusive and binding. Notwithstanding the foregoing, a dissolution or liquidation of the Company or a Corporate Transaction shall not be governed by this Section 12.1 but shall be governed by Sections 12.2 and 12.3, respectively. 12.2 Dissolution or Liquidation In the event of the proposed dissolution or liquidation of the Company, the Plan Administrator shall notify each Participant as soon as practicable prior to the effective date of such proposed transaction. The Plan Administrator in its discretion may permit a Participant to exercise an Option until ten days prior to such transaction with respect to all vested and exercisable shares of Common Stock covered thereby and with respect to such number of unvested shares as the Plan Administrator shall determine. In addition, the Plan Administrator may provide that any forfeiture provision or Company repurchase option applicable to any Award shall lapse as to such number of shares as the Plan Administrator shall determine, contingent upon the occurrence of the proposed dissolution or liquidation at the time and in the manner contemplated. To the extent an Option has not been previously exercised, the Option shall terminate automatically immediately prior to the consummation of the proposed action. To the extent a forfeiture provision applicable to a Stock Award has not been waived by the Plan Administrator, the Stock Award shall be forfeited automatically immediately prior to the consummation of the proposed action. 12.3 Corporate Transaction 12.3.1 Definitions "Corporate Transaction" means any of the following events: (a) Consummation of any merger or consolidation of the Company with or into another corporation; (b) Consummation of any sale, lease, exchange or other transfer in one transaction or a series of related transactions of all or substantially all the Company's outstanding securities or substantially all the Company's assets other than a transfer of the Company's assets to a majority-owned subsidiary corporation (as defined in Section 8.8) of the Company; or A-9

(c) Acquisition by a person, within the meaning of Section 3(a)(9) or of Section 13(d)(3) (as in effect on the date of adoption of the Plan) of the Exchange Act of a majority or more of the Company's outstanding voting securities (whether directly or indirectly, beneficially or of record). Ownership of voting securities shall take into account and shall include ownership as determined by applying Rule 13d-3(d)(1)(i) (as in effect on the date of adoption of the Plan) under the Exchange Act. "Related Party Transaction" means (i) a merger of the Company in which the holders of shares of Common Stock immediately prior to the merger hold at least a majority of the shares of Common Stock in the surviving corporation or parent thereof immediately after the merger, (ii) a mere reincorporation of the Company or (iii) a transaction undertaken for the sole purpose of creating a holding company. 12.3.2 Options In the event of a Corporate Transaction, except as otherwise provided in the instrument evidencing the Award or in written employment services agreement between a Participant and the Company or a Related Corporation in connection with an Award, each outstanding Option shall be assumed, continued or an equivalent option or right substituted by the surviving corporation, the successor corporation or its parent corporation, as applicable, (the "Successor Corporation"). If the Corporate Transaction is not a Related Party Transaction, upon consummation of the Corporate Transaction the assumed or substituted options shall automatically become fully vested and exercisable whether or not the vesting requirements set forth in the applicable option agreement have been satisfied. If the Corporate Transaction is a Related Party Transaction, the vesting schedule set forth in the instrument evidencing the Option shall continue to apply to the assumed or substituted options. In the event that the Successor Corporation refuses to assume or substitute for the Option, the Participant shall fully vest in and have the right to exercise the Option as to all of the shares of Common Stock subject thereto, including shares as to which the Option would not otherwise be vested or exercisable. If an Option will become fully vested and exercisable in lieu of assumption or substitution in the event of a Corporate Transaction, the Plan Administrator shall notify the Participant in writing or electronically that the Option shall be fully vested and exercisable for a specified time period after the date of such notice, and the Option shall terminate upon the expiration of such period, in each case conditioned on the consummation of the Corporate Transaction. For the purposes of this Section 12.3, the Option shall be considered assumed if, following the Corporate Transaction, the option or right confers the right to purchase or receive, for each share of Common Stock subject to the Option, immediately prior to the Corporate Transaction, the consideration (whether stock, cash, or other securities or property) received in the Corporate Transaction by holders of Common Stock for each share held on the effective date of the transaction (and if holders were offered a choice of consideration, the type of consideration chosen by the holders of a majority of the outstanding shares); provided, however, that if such consideration received in the Corporate Transaction is not solely common stock of the Successor Corporation, the Plan Administrator may, with the consent of the Successor Corporation, provide for the consideration to be received upon the exercise of the Option, for each share of Common Stock subject thereto, to be solely common stock of the Successor Corporation equal in fair market value to the per share consideration received by holders of Common Stock in the Corporate Transaction. All Options shall terminate and cease to remain outstanding immediately following the consummation of the Corporate Transaction, except to the extent assumed by the Successor Corporation. 12.3.3 Stock Awards In the event of a Corporate Transaction, except as otherwise provided in the instrument evidencing the Award or in a written employment or services agreement between a Participant and the Company or a Related Corporation in connection with an Award, the vesting of Shares subject to Stock Awards shall accelerate, and the forfeiture provisions to which such Shares are subject shall lapse, if and to the same extent that the vesting and exercisability of outstanding Options accelerate in connection with the Corporate Transaction. If unvested A-10

Options are to be assumed, continued or substituted by a Successor Corporation without acceleration upon the occurrence of a Corporate Transaction, the forfeiture provisions to which such shares are subject will continue with respect to shares of the Successor Corporation that may be issued in exchange for such Shares. 12.4 Further Adjustment of Awards Subject to Sections 12.2 and 12.3, the Plan Administrator shall have the discretion, exercisable at any time before a sale, merger, consolidation, reorganization, liquidation or change in control of the Company, as defined by the Plan Administrator, to take such further action as it determines to be necessary or advisable, and fair and equitable to the Participants, with respect to Awards. Such authorized action may include (but shall not be limited to) establishing, amending or waiving the type, terms, conditions or duration of, or restrictions on, Awards so as to provide for earlier, later, extended or additional time for exercise, lifting restrictions and other modifications, and the Plan Administrator may take such actions with respect to all Participants, to certain categories of Participants or only to individual Participants. The Plan Administrator may take such action before or after granting Awards to which the action relates and before or after any public announcement with respect to such sale, merger, consolidation, reorganization, liquidation or change in control that is the reason for such action. 12.5 Limitations The grant of Awards shall in no way affect the Company's right to adjust, reclassify, reorganize or otherwise change its capital or business structure or to merge, consolidate, dissolve, liquidate or sell or transfer all or any part of its business or assets. 12.6 Fractional Shares In the event of any adjustment in the number of shares covered by any Award, each such Award shall cover only the number of full shares resulting from such adjustment. SECTION 13. AMENDMENT AND TERMINATION OF PLAN 13.1 Amendment of Plan The Plan may be amended only by the Board in such respects as it shall deem advisable; provided, however, that to the extent required for compliance with Section 422 of the Code or any applicable law or regulation, shareholder approval shall be required for any amendment that would (a) increase the total number of shares available for issuance under the Plan, (b) modify the class of persons eligible to receive Options, or (c) otherwise require shareholder approval under any applicable law or regulation. Any amendment made to the Plan that would constitute a "modification" to Incentive Stock Options outstanding on the date of such amendment shall not, without the consent of the Participant, be applicable to such outstanding Incentive Stock Options but shall have prospective effect only. 13.2 Suspension or Termination of Plan The Board may suspend or terminate the Plan at any time. The Plan shall have no fixed expiration date; provided, however, that no Incentive Stock Options may be granted more than ten years after the later of (a) the Plan's adoption by the Board and (b) the adoption by the Board of any amendment to the Plan that constitutes the adoption of a new plan for purposes of Section 422 of the Code. 13.3 Consent of Participant The suspension, amendment or termination of the Plan or a portion thereof or the amendment of an outstanding Award shall not, without the Participant's consent, impair or diminish any rights or obligations under any Award theretofore granted to the Participant under the Plan. Any change or adjustment to an outstanding A-11

Incentive Stock Option shall not, without the consent of the Participant, be made in a manner so as to constitute a "modification" that would cause such Incentive Stock Option to fail to continue to qualify as an Incentive Stock Option. Notwithstanding the foregoing, any adjustments made pursuant to Section 12 shall not be subject to these restrictions. SECTION 14. GENERAL 14.1 Evidence of Awards Awards granted under the Plan shall be evidenced by a written instrument that shall contain such terms, conditions, limitations and restrictions as the Plan Administrator shall deem advisable and that are not inconsistent with the Plan. 14.2 No Individual Rights Nothing in the Plan or any Award granted under the Plan shall be deemed to constitute an employment contract or confer or be deemed to confer on any Participant any right to continue in the employ of, or to continue any other relationship with, the Company or any Related Corporation or limit in any way the right of the Company or any Related Corporation to terminate a Participant's employment or other relationship at any time, with or without Cause. 14.3 Registration Notwithstanding any other provision of the Plan, the Company shall have no obligation to issue or deliver any shares of Common Stock under the Plan or make any other distribution of benefits under the Plan unless such issuance, delivery or distribution would comply with all applicable laws (including, without limitation, the requirements of the Securities Act), and the applicable requirements of any securities exchange or similar entity. The Company shall be under no obligation to any Participant to register for offering or resale or to qualify for exemption under the Securities Act, or to register or qualify under state securities laws, any shares of Common Stock, security or interest in a security paid or issued under, or created by, the Plan, or to continue in effect any such registrations or qualifications if made. The Company may issue certificates for shares with such legends and subject to such restrictions on transfer and stop-transfer instructions as counsel for the Company deems necessary or desirable for compliance by the Company with federal and state securities laws. To the extent that the Plan or any instrument evidencing an Award provides for issuance of stock certificates to reflect the issuance of shares of Common Stock, the issuance may be effected on a noncertificated basis, to the extent not prohibited by applicable law or the applicable rules of any stock exchange. 14.4 No Rights as a Shareholder No Option or Stock Award denominated in units shall entitle the Participant to any cash dividend, voting or other right of a shareholder unless and until the date of issuance under the Plan of the shares that are the subject of such Award. 14.5 Compliance With Laws and Regulations Notwithstanding anything in the Plan to the contrary, the Plan Administrator, in its sole discretion, may bifurcate the Plan so as to restrict, limit or condition the use of any provision of the Plan to Participants who are officers or directors subject to Section 16 of the Exchange Act without so restricting, limiting or conditioning the Plan with respect to other Participants. Additionally, in interpreting and applying the provisions of the Plan, any Option granted as an Incentive Stock Option pursuant to the Plan shall, to the extent permitted by law, be construed as an "incentive stock option" within the meaning of Section 422 of the Code. A-12

14.6 Participants in Foreign Countries The Plan Administrator shall have the authority to adopt such modifications, procedures and subplans as may be necessary or desirable to comply with provisions of the laws of foreign countries in which the Company or its Related Corporations may operate to assure the viability of the benefits from Awards granted to Participants employed in such countries and to meet the objectives of the Plan. 14.7 No Trust or Fund The Plan is intended to constitute an "unfunded" plan. Nothing contained herein shall require the Company to segregate any monies or other property, or shares of Common Stock, or to create any trusts, or to make any special deposits for any immediate or deferred amounts payable to any Participant, and no Participant shall have any rights that are greater than those of a general unsecured creditor of the Company. 14.8 Severability If any provision of the Plan or any Award is determined to be invalid, illegal or unenforceable in any jurisdiction, or as to any person, or would disqualify the Plan or any Award under any law deemed applicable by the Plan Administrator, such provision shall be construed or deemed amended to conform to applicable laws, or, if it cannot be so construed or deemed amended without, in the Plan Administrator's determination, materially altering the intent of the Plan or the Award, such provision shall be stricken as to such jurisdiction, person or Award, and the remainder of the Plan and any such Award shall remain in full force and effect. 14.9 Choice of Law The Plan and all determinations made and actions taken pursuant hereto, to the extent not otherwise governed by the laws of the United States, shall be governed by the laws of the State of Washington without giving effect to principles of conflicts of laws. SECTION 15. EFFECTIVE DATE The Effective Date is the date on which the Plan is adopted by the Board, so long as it is approved by the Company's stockholders at any time within 12 months of such adoption. A-13

SECTION 6. PARTICIPATION IN THE PLAN 6.1 Initial Participation An Eligible Employee shall become a Participant on the first Offering Date after satisfying the eligibility requirements and delivering to the Company's payroll office not later than the last business day before such Offering Date (the "Subscription Date") a subscription agreement indicating the Eligible Employee's election to participate in the Plan and authorizing payroll deductions. An Eligible Employee who does not deliver a subscription agreement to the Company's payroll office on or before the Subscription Date shall not participate in the Plan for that Offering or for any subsequent Offering, unless such Eligible Employee subsequently enrolls in the Plan by filing a subscription agreement with the Company by the Subscription Date for such subsequent Offering. The Plan Administrator may, from time to time, change the Subscription Date as deemed advisable by the Plan Administrator in its sole discretion for the proper administration of the Plan. An employee who becomes eligible to participate in the Plan after an Offering has commenced shall not be eligible to participate in such Offering but may participate in any subsequent Offering, provided that such employee is still an Eligible Employee as of the commencement of any such subsequent Offering. Eligible Employees may not participate in more than one Offering at a time. 6.2 Continued Participation A Participant shall automatically participate in the next Offering until such time as such Participant withdraws from the Plan pursuant to Section 11.3 or terminates employment as provided in Section 13. If a Participant withdraws from an Offering pursuant to Section 11.2, the Participant is not required to file any additional subscription agreements for the next subsequent Offering in order to continue participation in the Plan, and the terms of a Participant's most recently filed subscription agreement shall govern the terms of such Participant's participation in the next Offering, unless the Participant indicates otherwise pursuant to Section 11. B-4

If a Participant is automatically withdrawn from an Offering at the end of a Purchase Period pursuant to Section 12, then the Participant shall automatically participate in the Offering commencing on the next regular business day. SECTION 7. LIMITATIONS ON RIGHT TO PURCHASE SHARES 7.1 $25,000 Limitation No Participant shall be entitled to purchase Stock under the Plan (or any other employee stock purchase plan that is intended to meet the requirements of Code Section 423 sponsored by the Company, a Parent Corporation or a Subsidiary Corporation) at a rate that exceeds $25,000 in Fair Market Value, determined as of the Offering Date for each Offering (or such other limit as may be imposed by the Code), for each calendar year in which a Participant participates in the Plan (or any other employee stock purchase plan described in this Section 7.1). 7.2 Number of Shares Purchased No Participant shall be entitled to purchase more than 250 shares of Stock (or such other number as the Plan Administrator shall specify for a future Offering) under the Plan in any Purchase Period. 7.3 Pro Rata Allocation In the event the number of shares of Stock that might be purchased by all Participants in the Plan exceeds the number of shares of Stock available in the Plan, the Plan Administrator shall make a pro rata allocation of the remaining shares of Stock in as uniform a manner as shall be practicable and as the Plan Administrator shall determine to be equitable. Fractional shares may be issued under the Plan only to the extent permitted by the Board or the Plan Administrator. SECTION 8. PURCHASE PRICE 8.1 General Rules The purchase price (the "Purchase Price") at which Stock may be acquired in an Offering pursuant to the exercise of all or any portion of an Option granted under the Plan shall be 85% of the lesser of (a) the Fair Market Value of the Stock on the Offering Date of such Offering and (b) the Fair Market Value of the Stock on the Purchase Date. Notwithstanding the foregoing, the Plan Administrator may establish a different Purchase Price for any Offering, which shall not be less than the Purchase Price set forth in the preceding sentence. 8.2 Change in Purchase Price Notwithstanding the foregoing, if an increase in the number of shares authorized for issuance under the Plan (other than an annual increase pursuant to Section 4) is approved and all or a portion of such additional shares are to be issued during one or more Offerings that are underway at the time of shareholder approval of such increase (the "Additional Shares"), then, if as of the date of such shareholder approval, the Fair Market Value of a share of Stock is higher than the Fair Market Value on the Offering Date for any such Offering, the Purchase Price for the Additional Shares shall be 85% of the lesser of (i) the Stock's Fair Market Value on the date of such shareholder approval and (ii) the Fair Market Value of the Stock on the Purchase Date. SECTION 9. PAYMENT OF PURCHASE PRICE 9.1 General Rules Subject to Section 9.11, Stock that is acquired pursuant to the exercise of all or any portion of an Option may be paid for only by means of payroll deductions from the Participant's Eligible Compensation. Except as set forth in this Section 9, the amount of compensation to be withheld from a Participant's Eligible Compensation during each pay period shall be determined by the Participant's subscription agreement. B-5

9.2 Amount Withheld The amount of payroll withholding with respect to the Plan for any Participant during any pay period shall be a fixed dollar amount or percentage of the Participant's Eligible Compensation, such amount to be, in either case, at least 1% of the Participant's Eligible Compensation for such pay period and not more than 10% of the Participant's Eligible Compensation for such pay period (or such other percentages as the Plan Administrator may establish for future Offerings). Amounts shall be withheld in whole dollars or percentages only, as applicable. 9.3 Payroll Deductions Payroll deductions shall commence on the first payday following the Offering Date and shall continue through the last payday of the Offering unless sooner altered or terminated as provided in the Plan. 9.4 Memorandum Accounts Individual accounts shall be maintained for each Participant for memorandum purposes only. All payroll deductions from a Participant's compensation shall be credited to such account, but shall be deposited with the general funds of the Company. All payroll deductions received or held by the Company may be used by the Company for any corporate purpose. 9.5 No Interest Interest shall not be paid on sums withheld from a Participant's compensation. 9.6 Acquisition of Stock Subject to Section 7, on each Purchase Date of an Offering, each Participant shall automatically acquire, pursuant to the exercise of the Participant's Option, the number of whole shares of Stock arrived at by dividing the total amount of the Participant's accumulated payroll deductions for the Purchase Period by the Purchase Price; provided, however, that in no event shall the number of shares of Stock purchased by the Participant exceed the number of shares of Stock subject to the Participant's Option. Fractional shares may be issued under the Plan only to the extent permitted by the Board or the Plan Administrator. 9.7 Refund of Excess Amounts Any cash balance remaining in the Participant's account shall be refunded to the Participant as soon as practical after the Purchase Date. In the event the cash to be returned to a Participant pursuant to the preceding sentence is an amount less than the amount necessary to purchase a whole share of Stock, and the Board or the Plan Administrator has determined that fractional shares may not be issued, the Plan Administrator may establish procedures whereby such cash is maintained in the Participant's account and applied to the purchase of Stock in the subsequent Purchase Period or Offering. If the Participant does not participate in the next Purchase Period, such remaining cash balance shall be refunded to the Participant as soon as practical after the Purchase Date without the payment of any interest. 9.8 Withholding Obligations At the time the Option is exercised, in whole or in part, or at the time some or all of the Stock is disposed of, the Participant shall make adequate provision for local, federal, state and foreign withholding obligations of the Company, if any, that arise upon exercise of the Option or upon disposition of the Stock. The Company may, but shall not be obligated to, withhold from the Participant's compensation the amount necessary to meet such withholding obligations. B-6

9.9 Termination of Participation No Stock shall be purchased on behalf of a Participant on a Purchase Date whose participation in a current Offering or the Plan has terminated on or before such Purchase Date. 9.10 Procedural Matters The Plan Administrator may, from time to time, establish (a) limitations on the frequency and/or number of changes in the amount withheld during an Offering, (b) an exchange ratio applicable to amounts withheld in a currency other than U.S. dollars, (c) payroll withholding in excess of the amount designated by a Participant in order to adjust for delays or mistakes in the Company's processing of properly completed withholding elections, and (d) such other limitations or procedures as deemed advisable by the Plan Administrator in the Plan Administrator's sole discretion that are consistent with the Plan and in accordance with the requirements of Code Section 423. 9.11 Leaves of Absence During leaves of absence approved by the Company and meeting the requirements of Treasury Regulations Section 1.421-7(h)(2), a Participant may continue participation in the Plan by delivering cash payments to the Company's payroll office on the Participant's normal paydays equal to the amount of his or her payroll deductions under the Plan had the Participant not taken a leave of absence. Currently, the Treasury Regulations provide that a Participant may continue participation in the Plan only during the first 90 days of a leave of absence unless the Participant's reemployment rights are guaranteed by statute or contract. SECTION 10. EVIDENCE OF STOCK OWNERSHIP Promptly following each Purchase Date, the number of shares of Stock purchased by each Participant shall be deposited into an account established in the Participant's name at a stock brokerage or other financial services firm designated or approved by the Plan Administrator (the "ESPP Broker"). A Participant shall be free to undertake a disposition of the shares of Stock in his or her account at any time, but, in the absence of such a disposition, the shares of Stock must remain in the Participant's account at the ESPP Broker until the holding periods set forth in Code Section 423(a) has been satisfied. With respect to shares of Stock for which the Code Section 423(a) holding periods have been satisfied, the Participant may move those shares of Stock to another brokerage account of the Participant's choosing or request that a stock certificate be issued and delivered to him or her. A Participant who is not subject to payment of U.S. income taxes may move his or her shares of Stock to another brokerage account of his or her choosing or request that a stock certificate be delivered to him or her at any time, without regard to the Code Section 423(a) holding periods. SECTION 11. CHANGES IN WITHHOLDING AMOUNTS AND VOLUNTARY WITHDRAWAL 11.1 Changes in Withholding Amounts (a) Unless the Plan Administrator establishes otherwise for a future Offering, during an Offering, a Participant may elect to decrease the amount withheld from his or her Eligible Compensation by filing an amended subscription agreement with the Company's payroll office on or before the seventh day prior to the end of the pay period for which such election is to be effective (the "Change Notice Date"); provided, however, that the Plan Administrator may change such Change Notice Date from time to time. An amended subscription agreement shall remain in effect until the Participant changes such agreement in accordance with the terms of the Plan. (b) Unless the Plan Administrator establishes otherwise for a future Offering, a Participant may elect to increase or decrease the amount to be withheld from his or her compensation for future Offerings by completing and filing an amended subscription agreement with the Company's payroll office by such Change Notice Date established by the Plan Administrator. An amended subscription agreement shall remain in effect until the Participant changes such agreement in accordance with the terms of the Plan. B-7

(c) Notwithstanding the foregoing, to the extent necessary to comply with Code Section 423 and Section 7.2, a Participant's payroll deductions shall be decreased to 0% during any Purchase Period if the aggregate of all payroll deductions accumulated with respect to one or more Purchase Periods ending within the same calendar year exceeds $25,000 of Fair Market Value of the Stock determined as of the first day of an Offering ($21,250 to the extent the Purchase Price may be 85% of the Fair Market Value of the Stock on the Offering Date of the Offering). Payroll deductions shall re-commence at the rate provided in such Participant's subscription agreement at the beginning of the first Purchase Period that is scheduled to end in the following calendar year, unless the Participant terminates participation in an Offering or the Plan as provided in Section 11.2 or Section 11.3 or indicates otherwise in an amended subscription agreement. Also notwithstanding the foregoing, a Participant's payroll deductions shall be decreased to 0% at such time that the aggregate of all payroll deductions accumulated with respect to a Purchase Period exceeds the amount necessary to purchase 250 shares of Stock in such Purchase Period (or such other number as the Board or Committee shall specify for a future Offering). Payroll deductions shall re-commence at the rate provided in such Participant's subscription agreement at the beginning of the next Purchase Period, provided the Participant continues to participate in the Plan and such participation complies with Section 7.2. 11.2 Withdrawal From an Offering A Participant may withdraw from an Offering by completing and delivering to the Company's payroll office a written notice of withdrawal on a form provided by the Plan Administrator for such purpose. Such withdrawal may be elected at any time prior to the end of an Offering; provided, however, that if a Participant withdraws after the Purchase Date for a Purchase Period of an Offering, the withdrawal shall not affect Stock acquired by the Participant in the earlier Purchase Periods. Unless otherwise indicated, withdrawal from an Offering shall not result in a withdrawal from the Plan or any succeeding Offering therein. A Participant is prohibited from again participating in the same Offering at any time upon withdrawal from such Offering. The Company may, from time to time, impose a requirement that the notice of withdrawal be on file with the Company's payroll office for a reasonable period prior to the effectiveness of the Participant's withdrawal. 11.3 Withdrawal From the Plan A Participant may withdraw from the Plan by signing a written notice of withdrawal on a form provided by the Plan Administrator for such purpose and delivering such notice to the Company's payroll office. In the event a Participant voluntarily elects to withdraw from the Plan, the withdrawing Participant may not resume participation in the Plan during the same Offering, but may participate in any subsequent Offering under the Plan by again satisfying the definition of Participant. The Company may, from time to time impose a requirement that the notice of withdrawal be on file with the Company's payroll office for a reasonable period prior to the effectiveness of the Participant's withdrawal. 11.4 Return of Payroll Deductions Upon withdrawal from an Offering pursuant to Section 11.2 or from the Plan pursuant to Section 11.3, the withdrawing Participant's accumulated payroll deductions that have not been applied to the purchase of Stock shall be returned as soon as practical after the withdrawal, without the payment of any interest, to the Participant, and the Participant's interest in the Offering shall terminate. Such accumulated payroll deductions may not be applied to any other Offering under the Plan. SECTION 12. AUTOMATIC WITHDRAWAL FROM AN OFFERING If the Fair Market Value of the Stock on a Purchase Date of an Offering (other than the final Purchase Date of such Offering) is less than the Fair Market Value of the shares on the Offering Date for such Offering and the Plan Administrator has established that the Purchase Price for the Offering may be the lesser of the Fair Market B-8

Value (or a percentage thereof) of the Stock on the Offering Date and the Fair Market Value of the Stock on the Purchase Date, then every Participant shall automatically (a) be withdrawn from such Offering at the close of such Purchase Date and (b) after the acquisition of Stock for such Purchase Period, be enrolled in the Offering commencing on the first business day subsequent to such Purchase Period. SECTION 13. TERMINATION OF EMPLOYMENT Termination of a Participant's employment with the Company for any reason, including retirement, death or the failure of a Participant to remain an Eligible Employee, shall immediately terminate the Participant's participation in the Plan. In such event, the payroll deductions credited to the Participant's account since the last Purchase Date shall, as soon as practical, be returned to the Participant or, in the case of a Participant's death, to the Participant's legal representative, and all the Participant's rights under the Plan shall terminate. Interest shall not be paid on sums returned to a Participant pursuant to this Section 13. SECTION 14. RESTRICTIONS UPON ASSIGNMENT 14.1 Transferability An Option granted under the Plan shall not be transferable otherwise than by will or the laws of descent and distribution, and is exercisable during the Participant's lifetime only by the Participant. The Plan Administrator will not recognize, and shall be under no duty to recognize, any assignment or purported assignment by a Participant, other than by will or the laws of descent and distribution, of the Participant's interest in the Plan, of his or her Option or of any rights under his or her Option. 14.2 Beneficiary Designation A Participant may designate on a Company-approved form a beneficiary who is to receive any shares and cash, if any, from the Participant's account under the Plan in the event the Participant dies after the Purchase Date for an Offering but prior to delivery to such Participant of such shares and cash. In addition, a Participant may designate on a Company-approved form a beneficiary who is to receive any cash from the Participant's account under the Plan in the event that the Participant dies before the Purchase Date for an Offering. Such designation may be changed by the Participant at any time by written notice to the Company. SECTION 15. NO RIGHTS OF SHAREHOLDER UNTIL SHARES ISSUED With respect to shares of Stock subject to an Option, a Participant shall not be deemed to be a shareholder of the Company, and he or she shall not have any of the rights or privileges of a shareholder. A Participant shall have the rights and privileges of a shareholder of the Company when, but not until, the shares have been issued following exercise of the Participant's Option. SECTION 16. LIMITATIONS ON SALE OF STOCK PURCHASED UNDER THE PLAN The Plan is intended to provide Stock for investment and not for resale. The Company does not, however, intend to restrict or influence any Participant in the conduct of his or her own affairs. A Participant, therefore, may sell Stock purchased under the Plan at any time he or she chooses subject to compliance with Company policies and any applicable federal and state securities laws. A Participant assumes the risk of any market fluctuations in the price of the Stock. SECTION 17. AMENDMENT OF THE PLAN The Board may amend the Plan in such respects as it shall deem advisable; provided, however, that to the extent required for compliance with Code Section 423 or any applicable law or regulation, shareholder approval will be required for any amendment that will (a) increase the total number of shares as to which Options may be B-9

granted under the Plan, (b) modify the class of persons eligible to receive Options, or (c) otherwise require shareholder approval under any applicable law or regulation; and provided further, no amendment to the Plan shall make any change in any Option previously granted which adversely affects the rights of any Participant. SECTION 18. SUSPENSION OR TERMINATION OF THE PLAN The Board may suspend or terminate the Plan at any time. Unless the Plan shall theretofore have been terminated by the Board, the Plan shall terminate on, and no Options shall be granted after May 24, 2012. No Options shall be granted during any period of suspension of the Plan. Except as provided in Section 21, no such termination of the Plan may affect Options previously granted; provided, however, that the Plan or an Offering may be terminated by the Board on a Purchase Date or by the Board's setting a new Purchase Date with respect to an Offering and a Purchase Period then in progress if the Board determines that termination of the Plan and/or the Offering is in the best interests of the Company and the shareholders or if continuation of the Plan and/or the Offering would cause the Company to incur adverse accounting charges as a result of a change in the generally accepted accounting rules applicable to the Plan. SECTION 19. NO RIGHTS AS AN EMPLOYEE Nothing in the Plan shall be construed to give any person (including any Eligible Employee or Participant) the right to remain in the employ of the Company or a Parent Corporation or Subsidiary Corporation or to affect the right of the Company and the Parent Corporations and Subsidiary Corporations to terminate the employment of any person (including any Eligible Employee or Participant) at any time with or without cause. SECTION 20. EFFECT UPON OTHER PLANS The adoption of the Plan shall not affect any other compensation or incentive plans in effect for the Company or any Parent Corporation or Subsidiary Corporation. Nothing in the Plan shall be construed to limit the right of the Company, any Parent Corporation or any Subsidiary Corporation to (a) establish any other forms of incentives or compensation for employees of the Company, any Parent Corporation or any Subsidiary Corporation or (b) grant or assume options otherwise than under the Plan in connection with any proper corporate purpose, including, but not by way of limitation, the grant or assumption of options in connection with the acquisition, by purchase, lease merger, consolidation or otherwise, of the business, stock or assets of any corporation, firm or association. SECTION 21. ADJUSTMENTS 21.1 Adjustment of Shares In the event that, at any time or from time to time, a stock dividend, stock split, spin-off, combination or exchange of shares, recapitalization, merger, consolidation, distribution to shareholders other than a normal cash dividend, or other change in the Company's corporate or capital structure results in (a) the outstanding shares, or any securities exchanged therefor or received in their place, being exchanged for a different number or class of securities of the Company or of any other corporation or (b) new, different or additional securities of the Company or of any other corporation being received by the holders of shares of Stock, then the Plan Administrator, in its sole discretion, shall make such equitable adjustments as it shall deem appropriate in the circumstances in (i) the maximum number and kind of shares of Stock subject to the Plan as set forth in Section 4, (ii) the maximum number and kind of securities that are subject to any outstanding Option and the per share price of such securities and (iii) the maximum number and kind of shares of Stock that may be purchased by a Participant in a Purchase Period. The determination by the Plan Administrator as to the terms of any of the foregoing adjustments shall be conclusive and binding. Notwithstanding the foregoing, a dissolution, liquidation or Company Transaction shall not be governed by this Section 21.1 but shall be governed by Sections 21.2 and 21.3, respectively. B-10

21.2 Dissolution or Liquidation of the Company In the event of the proposed dissolution or liquidation of the Company, the Offering then in progress shall be shortened by setting a new Purchase Date and shall terminate immediately prior to the consummation of such proposed dissolution or liquidation, unless provided otherwise by the Board. The new Purchase Date shall be a specified date before the date of the Company's proposed dissolution or liquidation. The Board shall notify each Participant in writing prior to the new Purchase Date that the Purchase Date for the Participant's Option has been changed to the new Purchase Date and that the Participant's Option shall be exercised automatically on the new Purchase Date, unless prior to such date the Participant has withdrawn from an Offering then in progress or the Plan as provided in Section 11. 21.3 Company Transaction In the event of a proposed Company Transaction, each outstanding Option shall be assumed or an equivalent option substituted by the successor company or parent thereof (the "Successor Corporation"). In the event that the Successor Corporation refuses to assume or substitute for the Option, any Offering then in progress shall be shortened by setting a new Purchase Date. The new Purchase Date shall be a specified date before the date of the Company Transaction. The Board shall notify each Participant in writing, prior to the new Purchase Date, that the Purchase Date for the Participant's Option has been changed to the new Purchase Date and that the Participant's Option shall be exercised automatically on the new Purchase Date, unless prior to such date the Participant has withdrawn from an Offering then in progress or the Plan as provided in Section 11. 21.4 Limitations The grant of Options will in no way affect the Company's right to adjust, reclassify, reorganize or otherwise change its capital or business structure or to merge, consolidate, dissolve, liquidate or sell or transfer all or any part of its business or assets. SECTION 22. REGISTRATION; CERTIFICATES FOR SHARES The Company shall be under no obligation to any Participant to register for offering or resale under the Securities Act of 1933, as amended, or register or qualify under state securities laws, any shares of Stock. The Company may issue certificates for shares with such legends and subject to such restrictions on transfer and stop-transfer instructions as counsel for the Company deems necessary or desirable for compliance by the Company with federal and state securities laws. SECTION 23. EFFECTIVE DATE The Plan's effective date is the date on which it is approved by the Company's shareholders. B-11
