AMERICAN ECOLOGY CORPORATION
ANNUAL MEETING OF STOCKHOLDERS
TO BE HELD ON MAY 29, 2003

PROXY STATEMENT

This Proxy Statement relates to the Annual Meeting of Stockholders of American Ecology Corporation, (the "Company"), a Delaware corporation, to be held on May 29, 2003, at 10:00 a.m., at the Standard Club in the Chicago Room 4th Floor, 320 S. Plymouth Court, Chicago, Illinois 60604, including any adjournments or postponements thereof (the "Meeting"). This Proxy Statement, the accompanying proxy card and the Company's Annual Report are first being mailed to stockholders of the Company on or about April 25, 2003. THEY ARE FURNISHED IN CONNECTION WITH THE SOLICITATION BY THE COMPANY OF PROXIES FROM THE HOLDERS OF THE COMPANY'S COMMON STOCK, PAR VALUE $.01 PER SHARE ("COMMON STOCK"), FOR USE AT THE MEETING.

The principal solicitation of proxies is being made by mail; however, additional solicitation may be made by telephone, facsimile or personal visits by directors, officers and regular employees of the Company and its subsidiaries, who will not receive additional compensation. The Company will reimburse brokerage firms and others for their reasonable expenses in forwarding soliciting material.

All shares represented by duly executed proxies in the accompanying form received prior to the Meeting will be voted in the manner specified therein. Any stockholder granting a proxy may revoke it at any time before it is voted by filing with the Secretary of the Company either an instrument revoking the proxy or a duly executed proxy bearing a later date. Any stockholder present at the Meeting who expresses a desire to vote their shares in person may also revoke their proxy. As to any matter for which no choice has been specified in a duly executed proxy, the shares represented thereby will be voted FOR each proposal listed herein and in the discretion of the persons named in the proxy in any other business that may properly come before the Meeting.

STOCKHOLDERS ARE URGED, WHETHER OR NOT THEY EXPECT TO ATTEND THE MEETING, TO COMPLETE, SIGN AND DATE THE ACCOMPANYING PROXY AND RETURN IT PROMPTLY IN THE ENCLOSED ENVELOPE.

The Company's Annual Report to Stockholders for the fiscal year ended December 31, 2002 is being furnished with this Proxy Statement to stockholders of record as of March 31, 2003. The Annual Report to Stockholders does not constitute a part of the proxy solicitation material except as otherwise provided by the rules of the Securities and Exchange Commission, or as expressly provided for herein.

OUTSTANDING SHARES AND VOTING RIGHTS

The Board of Directors of the Company fixed March 31, 2003 as the record date ("Record Date") for the determination of stockholders entitled to notice of and to vote at the Meeting. On the Record Date, there were 16,960,901 shares of common stock issued, outstanding and entitled to vote. The Company has no other voting securities outstanding. Each stockholder of record is entitled to one vote per share held on all matters submitted to a vote of stockholders, except that in electing directors, each stockholder is entitled to cumulate his or her votes and give any one candidate an aggregate number of votes equal to the number of directors to be elected (seven) multiplied by the number of his or her shares, or to distribute such aggregate number of votes among as many candidates

3

as he or she chooses. For a stockholder to exercise cumulative voting rights, the stockholder must give notice of his or her intention to cumulatively vote prior to the Meeting, or at the Meeting in person, prior to voting. If any stockholder has given such notice, all stockholders may cumulatively vote. The holders of proxies will have authority to cumulatively vote and allocate such votes in their discretion to one or more of the director nominees. The holders of the proxies solicited hereby do not, at this time, intend to cumulatively vote the shares they represent, unless a stockholder indicates his intent to do so, in which instance the proxy holders intend to cumulatively vote all the shares they hold by proxy in favor of some or all of the director nominees identified herein.

The holders of a majority of the outstanding shares of common stock on the Record Date present at the Meeting in person or by proxy will constitute a quorum for the transaction of business at the meeting. An affirmative vote of a majority of the shares present and voting at the Meeting is required for approval of all matters. Abstentions and broker non-votes are each included in the determination of the number of shares present. Abstentions are counted in tabulations of the votes cast on proposals presented to stockholders, and thus, have the effect of voting against a proposal, whereas broker non-votes are not counted for purposes of determining whether a proposal has been approved.

PROPOSAL NO. 1

ELECTION OF DIRECTORS

DIRECTORS.

At the Meeting, seven directors are to be elected to hold office until the next Annual Meeting of Stockholders or until the election and qualification of their respective successor. It is the intention of the persons named in the proxy to vote the proxies that are not marked to the contrary for the election as directors of the persons named below as nominees. If any such nominee refuses or is unable to serve as a director, the persons named as proxies may in their discretion vote for any or all other persons who may be nominated. The seven nominees receiving the greatest number of votes cast will be elected directors if each nominee receives at least a majority of the votes cast.

During the year ended December 31, 2002, the Board of Directors held nine meetings. Each of the directors attended at least 75% of the meetings of the Board and the Committees on which they served during the period for which they were a Board or Committee member, respectively.

The Committees of the Board of Directors during 2002 were the Nominating, Executive, Audit and Compensation Committees.

The members of the Nominating Committee are currently Messrs. Hickey, Romano, and Eliff. Mr. Hickey is chairman. The Nominating Committee searches for and recommends to the Board of Directors, qualified and experienced individuals to fill vacancies and new director seats upon expansion of the board.

The Committee is also charged with reviewing transactions that may present a conflict of interest on the part of management or directors. The Audit Committee meets at least quarterly to review the financial results, discuss the financial statements and make recommendations to the Board. Other items of discussion include the independent auditors' recommendations for internal controls, adequacy of staff, and management's performance concerning audit and financial controls. The Audit Committee met six times in 2002, including a visit to the Company's Corporate office in Boise, Idaho and its Grand View, Idaho waste treatment and disposal facility.

SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE.

Section 16 of the Securities Exchange Act of 1934 ("Section 16") requires that reports of beneficial ownership of common stock and preferred stock and changes in such ownership be filed with the Securities and Exchange Commission by
Section 16 "reporting persons" including directors, certain officers, holders of more than 10% of the outstanding common stock or preferred stock, and certain trusts of which reporting persons are trustees. The Company is required to disclose in this proxy statement each reporting person whom it knows has failed to file any required reports under Section 16 on a timely basis. Based solely upon a review of copies of Section 16 reports furnished to the Company for the year ended December 31, 2002 and written statements confirming that no other reports were required, to the Company's knowledge, all Section 16 reporting requirements applicable to known reporting persons were made timely throughout the year except for the late filing by John Couzens, a former director, of his Form 4 statement for a transaction on December 4, 2002 filed December 11, 2002 rather than December 6, 2002 as required.

CORPORATE GOVERNANCE RESPONSIBILITY

The Board of Directors is ultimately responsible for the Company's corporate governance. Good corporate governance ensures that the Company complies with legal requirements such as the Sarbanes-Oxley Act of 2002. During 2003, the Company anticipates amending the Audit Committee Charter as well as amending and adopting additional policies and procedures as needed to further ensure good corporate governance.

COMPENSATION COMMITTEE REPORT.

The Compensation Committee of the Board of Directors is composed of outside directors and is responsible for developing and making recommendations to the Board with respect to the Company's executive compensation policies. The Committee also reviews and approves the Company's compensation and benefit plans and administers the 1992 Employee Stock Option Plan. The following report describes the basis on which the Compensation Committee made 2002 compensation determinations for executive officers of the Company.

The Company believes that executive compensation should reflect value created for stockholders in furtherance of the Company's strategic goals. The following objectives are among those utilized by the Compensation Committee:

1. Executive compensation should be meaningfully related to long-term and short-term value created for stockholders.
2. Executive compensation programs should support the long-term and short-term strategic goals and objectives of the Company.
3. Executive compensation programs should reflect and promote the Company's overall value, business growth and reward individuals for outstanding contributions to the Company.
4. Short and long term executive compensation are critical factors in attracting and retaining well-qualified executives.

Currently the Company has a compensation program based on three components: a base salary, bonus payments tied to Company performance, and a stock option program. The Compensation Committee regularly reviews the various components of the compensation program to ensure that they are consistent with the Company's objectives.

BASE SALARY -- The Compensation Committee, in determining the appropriate base salaries of its executive officers, generally considers the level of executive compensation in similar companies in the industry. The Compensation Committee also considers (i) the performance of the Company and contributing roles of the individual executive officers, (ii) the particular executive officer's specific experience and responsibilities, and (iii) the performance of each executive officer. The base salaries for 2002 were established by the Committee at levels believed to be competitive with amounts paid to executives of companies in the environmental industry with comparable qualifications, experience and responsibilities. During 2002, the base salary of Stephen A. Romano was increased by the Committee to $178,000. The Committee believes this to be

10

consistent with the base salary of executive officers with comparable qualifications, experience and responsibilities of other companies in the environmental industry. In recognition of Mr. Romano's performance as Chief Executive Officer, on February 11, 2003 the Committee approved an employment contract for Mr. Romano providing for a minimum annual base salary of $205,000 and an expiration date of December 31, 2005.

ANNUAL INCENTIVES -- The management incentive plan in effect during 2002 allowed for direct financial incentives to select individuals in the form of a cash bonus for exceeding the Company's goals or for outstanding performance. Based on the Company's financial performance in 2002, cash bonuses were awarded to executives and key employees as specified by the 2002 management incentive plan. Effective January 1, 2003, the Committee approved a Management Incentive Plan covering executive incentive compensation for Company performance through 2005. Other key employee incentives will be evaluated during 2003.

LONG-TERM INCENTIVES -- The stock option program is the Company's long-term incentive plan for executive officers and key employees. The objectives of the stock option program are to align executive officer compensation and shareholder return, and to enable executive officers to develop and maintain a significant, long-term stock ownership position in the Company's common stock. In addition, grants of stock options to executive officers and others are intended to retain and motivate executives to improve long-term corporate and common share performance. Stock options are generally granted at no less than market value on the grant date, and will only have value if the Company's stock price increases above the grant price. In furtherance of these objectives, the Committee approved the grant of 97,500 options to certain executives and key employees during 2002. On February 11, 2003 the Committee approved the grant of an additional 758,724 shares to certain executives and key employees.

This report is respectfully submitted by the Compensation Committee of the Company's Board of Directors:

Paul F. Schutt, Compensation Committee Chairman Rotchford L. Barker
Roger P. Hickey

AUDIT COMMITTEE REPORT, CHARTER, INDEPENDENCE

The Audit Committee has reviewed and discussed the Company's audited financial statements with management. The Audit Committee has discussed with Moss Adams, the Company's independent auditors, the matters required to be discussed by Statement on Auditing Standards 61, which includes, among other items, matters related to the conduct of the audit of the Company's financial statements.

The Audit Committee has received written disclosures and the letter from the auditors required by Independence Standards Board Standard No. 1, which relates to the auditor's independence from the Company and its related entities, and has discussed with the auditors the auditor's independence from the Company. The Audit Committee has considered whether the provision of services by the auditors, other than audit services and review of Forms 10-Q, is compatible with maintaining the auditor's independence.

Based on the review and discussions of the Company's audited financial statements with management and discussion with the independent auditors, the Audit Committee recommended to the Board of Directors that the Company's audited financial statements be included in the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2002.

11

While the Audit Committee has performed the functions of board-level oversight, advice and direction, management is responsible for the financial statements and system of internal controls. Similarly, it is the responsibility of the independent accountants, and not the Audit Committee, to conduct the audit and express an opinion as to the conformity of the financial statements with accounting principles generally accepted in the United States.

This report is respectfully submitted by the Audit Committee of the Company's Board of Directors:

Roy C. Eliff, Audit Committee Chairman
David B. Anderson
Paul F. Schutt

AUDIT COMMITTEE CHARTER

The Board of Directors has adopted a written charter for the Audit Committee that was filed with the 2001 annual meeting proxy.

AUDIT COMMITTEE INDEPENDENCE

The Board of Directors has determined that Messrs. Eliff, Anderson, and Schutt all meet the requirements for independence set forth in the Listing Standards of the National Association of Securities Dealers.

PROPOSAL NO. 2
SELECTION OF AUDITORS

The Board of Directors has selected Moss Adams LLP, as independent auditors for the Company's 2003 fiscal year. Moss Adams has examined the financial statements of the Company for its 2002 fiscal year. A representative of Moss Adams is expected to be present at the Annual Meeting and will be available to make a statement or respond to questions.

Stockholder ratification of the selection of Moss Adams as the Company's independent accountants is not required by the Company's Articles, Bylaws or otherwise. However, the Board is submitting the selection of Moss Adams to the stockholders for ratification as a matter of good corporate practice, and recommends that the stockholders vote for approval. If the stockholders fail to ratify the selection, the Board, in conjunction with the Audit Committee may reconsider whether or not to retain that firm. Even if the selection is ratified, the Board and the Audit Committee in their discretion may direct the appointment of a different independent accounting firm at any time during the year if they determine that such a change would be in the best interests of the Company and its stockholders.

The affirmative vote of the holders of a majority of the shares present in person or represented by proxy and entitled to vote at the meeting is requested to ratify the selection of Moss Adams. Abstentions will be counted toward the tabulation of votes cast on this Proposal No. 2 and will have the same effect as negative votes. Broker non-votes are counted towards a quorum, but are not counted for any purpose in determining whether this matter has been ratified.

AUDITOR FEES

The aggregate fees billed by Moss Adams, for professional services rendered for the audit of the Company's annual financial statements and the review of the financial statements included in the Company's third quarter report on Form 10-Q, for the fiscal year ended December 31, 2002 were $66,000.

PROPOSAL NO. 3

AMENDMENT OF 1992 EMPLOYEE STOCK OPTION PLAN
TO EXTEND TERM OF PLAN

The Company currently maintains one Stock Option Plan (the "Plan"), first adopted in 1992, amended in 1994, and amended and restated in 1999, which provides employees of the Company additional incentive for their service. There are currently 92,926 options available for grant under the Plan. However, the Plan currently expires on March 3, 2004, after which date no new options can be granted.

In the past, the Company has used stock options to attract and retain key employees, believing that employee stock ownership and stock-related compensation encourage parallel interests between employees and shareholders. In order to be able to continue issuing options, the Board of Directors determined it is necessary and appropriate to amend the Plan. Accordingly, on April 7, 2003, the Board approved an amendment to extend the term of the Plan for ten years from such date and directed that the amendment be submitted to stockholders for approval and ratification.

The following is a summary of the principal features of the current Plan, a copy of which is attached hereto as Exhibit A.

Shares Subject to the Plan. Currently, up to an aggregate of 1,300,000 shares of the Company's Common Stock may be issued under the Plan. The proposed amendment would not increase the number of shares which could be issued. Shares which are not issued prior to expiration or termination of an option will be available for future option grants and do not increase the aggregate number of shares available under the Plan. The Plan provides for appropriate adjustment of shares available under the Plan and of shares subject to outstanding options in the event of any changes in the outstanding Common Stock of the Company by reason of recapitalization, reclassification, stock dividend, stock split, reverse stock split or other similar transaction.

Type of Options. Two types of options may be granted under the Plan: (1) options intended to qualify as incentive stock options under the Internal Revenue Code, and (2) non-qualified stock options not specifically authorized or qualified for preferential federal income tax consequences. Generally, gains on the stock purchased through the exercise of incentive stock options are taxed to the recipient upon the sale of the stock. Gains in respect of non-qualified stock options are taxed upon the exercise of the option.

Administration. The Plan is administered by the Company's Compensation Committee which is comprised of directors who are not eligible to participate the Plan.

Eligibility and Participation. All employees, including employee directors, of the Company are eligible to participate in the Plan.

Rights as a Stockholder. Except as expressly provided in the Plan, the recipient of an option has no rights as a stockholder (such as voting or dividends) with respect to shares covered by the recipient's option until the date of issuance of a stock certificate for such shares.

Transferability. During the life of the option holder, any stock option will be exercisable only by the recipient, and will be transferable only by will or the laws of descent and distribution or pursuant to a qualified domestic relations order.

17

Duration of the Plan. The Plan is effective until all options have been granted under the Plan or ten years from March 3, 1994, the date the Plan was last restated and approved. The proposed amendment would extend this date to April 7, 2013.

Purchase Price. The purchase price payable to exercise an option must be at least the fair market value of the Common Stock on the date the option is granted. Payment in full for the number of shares purchased upon the exercise of options is required. On April 3, 2003 the closing price for the Common Stock on the NASDAQ National Market was $2.76 per share.

Basic Terms of Options. Each option is evidenced by a stock option agreement containing terms and conditions not inconsistent with the provisions of the Plan. The Compensation Committee has discretion to set vesting schedules for options. When vested, options are exercisable in whole or in part upon grant until the option terminates or expires. Options expire within ten years of grant and terminate 30 days after termination of employment or one year following the death of the holder.

The Board of Directors recommends that stockholders vote FOR the proposed amendment to extend the term of the Plan. Proposal No. 3 will be adopted if a majority of the outstanding common stock represented at the Meeting is voted in favor.

EXHIBIT A

AMERICAN ECOLOGY CORPORATION
SECOND AMENDED AND RESTATED 1992 STOCK OPTION PLAN

ARTICLE I
PURPOSE
The purpose of this Second Amended and Restated 1992 Stock Option Plan (the "Plan") of American Ecology Corporation, a Delaware corporation (the "Company") is to secure for the Company and its shareholders the benefits arising from stock ownership by selected executive and other key employees of the Company or its subsidiaries as the Board of Directors of the Company (the "Board"), or a Committee constituted for such purpose, may from time to time determine. The Plan will provide a means whereby (i) such employees may purchase shares of the Common Stock of the Company pursuant to stock options which will qualify as "incentive stock options" under Section 422 of the Internal Revenue Code of 1986, as amended (the "Code") and (ii) such employees or other persons may purchase shares of the Common Stock of the Company pursuant to "non-incentive" or "non-qualified" stock options.

ARTICLE II
ADMINISTRATION
The Plan shall be administered by the Compensation Committee. The Committee shall at all times consist of not less than two members of the Board, and shall not include any persons that are not members of the Board. All members of the Committee shall be selected by (and serve at the pleasure of) the Board. All members of the Committee shall be "disinterested persons" within the meaning of Rule 16b-3 of the General Rules and Regulations under the Securities Act of 1934, as amended (the "1934 Act"). Subject to the express provisions of the Plan and the policies of each stock exchange on which any of the Company's stock may at any time be traded, the Committee shall have plenary authority, in its discretion, to recommend to the Board the individuals within the class set forth in Article IV to whom, and the time and price per share at which, stock options shall be granted, the number of shares to be subject to each stock option and the other terms and provisions of their respective Agreements (as defined herein), which need not be identical. In making such recommendations and determinations, the Committee may take into account the nature of the services rendered by the respective employees, their present and potential contributions to the Company's success and such other factors as the Committee in its discretion shall deem relevant.

Subject to the express provisions of the Plan, the Committee shall have authority (i) to construe and interpret the Plan, (ii) to define the terms used therein, (iii) to prescribe, amend and rescind rules and regulations relating to the Plan (iv) to recommend to the Board the terms and provisions of the respective stock options, (v) to approve and determine the duration of leaves of absence which may be granted to participants without constituting a termination of their employment for the purposes of the Plan, and (vi) to make all other determinations necessary or advisable for the administration of the Plan. All determinations and interpretations made by the Committee shall be binding and conclusive on all participants in the Plan and their legal representatives and beneficiaries. The Committee shall hold meetings at such time and places as it may determine. Acts by the majority of the Committee or acts reduced to or approved in writing by a majority of the members of the Committee shall be the valid acts of the Committee. From time to time, the Board may increase the size of the Committee and appoint additional members thereof, remove members (with or without cause), and appoint new members in substitution therefor, or fill vacancies however caused, subject to the requirements that the members of the Committee shall be "disinterested persons" as described above and that there always be at least two members of the Committee. No member of the Committee shall be liable for any action, failure to act, determination or interpretation made in good faith with respect to the Plan or any transaction under the Plan.

20

ARTICLE III
SHARES SUBJECT TO PLAN AND DURATION OF PLAN
Under the Plan, the Board may, but only upon recommendation of the Committee, grant to eligible persons incentive stock options (as defined in the Code) and/or non-qualified stock options, to purchase up to but not exceeding an aggregate amount of 1,300,000 shares of the Company's common stock, $0.01 per share par value ("Common Stock"). Shares subject to stock options under the Plan may be either authorized and unissued shares or issued shares that have been acquired by the Company and held in its treasury, in the sole discretion of the Board. When stock options have been granted under the Plan and have lapsed unexercised or partially unexercised or have been surrendered for cancellation by the optionee thereof, the unexercised shares which were subject thereto may be reoptioned under the Plan. No stock options shall be granted more than ten years after the effective date of the Plan or after April 7, 2013.

ARTICLE 1V
ELIGIBILITY AND PARTICIPATION
To the fullest extent permitted by applicable laws, all executive and other key employees of the Company or of any subsidiary corporation (as defined in Section 424(f) of the Code) shall be eligible for selection to fully participate in the Plan; provided, however, that no member of the Committee shall be entitled to receive a stock option under this Plan while serving as a member of the Committee. Directors of the Company who are not regular employees of the Company are not eligible to participate in the Plan. An individual who has been granted a stock option may, if such individual is otherwise eligible, be granted an additional stock option or options if the Board or the Committee shall so determine, subject to the other provisions of the Plan.

ARTICLE V
TERMS AND CONDITIONS OF STOCK OPTIONS
Each stock option granted under the Plan shall be evidenced by a stock option agreement (the "Agreement"), the form of which shall have been approved by the Committee. The Agreement shall be executed by the Company and the optionee and shall set forth the terms and conditions of the stock option, which terms and conditions shall include, but not be limited to the following:

Stock Option Price. The stock option price shall be determined by the Committee, but shall not in any event be less than the par value of the Common Stock.

Term of Stock Option. The term of the stock option shall be selected by the Committee, but in no event shall such term exceed ten years from the date such stock option is granted. Each such stock option shall be subject to earlier termination as hereinafter provided.

Transferability. The stock options granted hereunder shall not be transferable other than by will or operation of the laws of descent and distribution or pursuant to a qualified domestic relations order as defined in the Code or Title I of the Employee Retirement Income Security Act, or the rules thereunder. During the lifetime of the optionee, stock options granted hereunder shall be exercisable only by the optionee or the optionee's guardian or legal representative.

Vesting. The Committee shall have complete discretion in determining when stock options granted hereunder are to vest; provided, however, that the sale of shares issued on the exercise of a stock option by any person subject to Section 16 of the 1934 Act shall not be allowed until at least six months after the

21

later of (i) the approval of this Plan by the shareholders of the Company in accordance with Article XV hereof or (ii) the grant of the stock option. Such determination for each stock option is to be made prior to or at the time that the stock option is granted.

Termination of Employment. In the event of an optionee's termination of employment with the Company for any reason other than death, all stock options shall terminate to the extent they were not exercisable at the date of the optionee's termination, but to the extent they were then exercisable by the optionee, the optionee shall be entitled to exercise such stock options for a period of 30 days from the date of the optionee's termination. Upon the termination of an optionee's employment by reason of death, the optionee's stock options shall terminate to the extent they were not exercisable at the date of the optionee's death, but to the extent they were then exercisable by the optionee, the optionee's estate or the beneficiaries thereof shall be entitled to exercise such stock options for a period of one year from the date of the optionee's death but not thereafter. Notwithstanding any other provisions of this subparagraph (e), no stock option shall be exercised after the expiration of ten years from the date such stock option is granted.

Other Conditions. At its sole discretion, the Committee may impose other conditions upon the stock options granted hereunder, so long as those conditions do not conflict with any other provisions of the Plan. Such conditions may include, by way of illustration, but not by way of limitation, percentage limitations upon the exercisability of stock options granted hereunder.

ARTICLE VI
INCENTIVE STOCK OPTIONS
The Committee and the Board, in recommending and granting stock options hereunder, shall have the discretion to determine that certain stock options shall be incentive stock options, as defined in Section 422 of the Code, while other stock options shall be non-qualified stock options. Neither the members of the Committee, the members of the Board nor the Company shall be under any obligation or incur any liability to any person by reason of determination by the Committee or the Board whether a stock option granted under the Plan shall be an incentive stock option or a non-qualified stock option. The provisions of this Article VI shall be applicable to all incentive stock options at any time granted or outstanding under the Plan.

All incentive stock options granted or outstanding under the Plan shall be granted and held subject and in compliance with terms and conditions physically set forth in Articles II, III, IV and V hereof, and, in addition, subject to and in compliance with the following further terms and conditions:

The stock option price of all incentive stock options shall not be less than 100% of the Fair Market Value (as defined below) of one share of the Company's Common Stock at the time the stock option is granted (not withstanding any provision of Article V hereof to the contrary);

No incentive stock option shall be granted to any person who, at the time of the grant, owns stock possessing more than 10% of the total combined voting power of all classes of stock of the Company or any subsidiary corporation of the Company, provided, however, that this ownership limitation will be waived if at the time the stock option is granted the stock option price is at least 110% of the Fair Market Value of one share of the Company's Common Stock and such stock option by its terms is not exercisable after the expiration of five years from the date such option is granted;

An incentive stock option shall not be transferable other than by will or by laws of descent and distribution, and shall be exercisable during the lifetime of the optionee, only by the optionee; and

22

The aggregate Fair Market Value of all shares of Common Stock (determined at the time of the grant of the stock option) with respect to which incentive stock options are exercisable for the first time by any optionee during any one calendar year shall not exceed $100,000.

ARTICLE VII
EXERCISE OF STOCK OPTIONS
Each stock option granted hereunder may be exercised in such installments during the period prior to its expiration date as the Board or the Committee shall determine; provided that, unless otherwise determined by the Board or Committee, if the optionee shall not in any given installment period purchase all of the shares which the optionee is entitled to purchase in such installment period, then the optionee's right to purchase any shares not purchased in such installment period shall continue until the expiration date or sooner termination of the optionee's stock option. No stock option may be exercised for a fraction of a share and no partial exercise of any stock option may be for less than 100 shares.

The purchase price of the shares of Common Stock acquired upon exercise of a stock option shall be paid in full at the time of exercise in cash or by certified or cashier's check payable to the order of the Company, or, upon receipt of all required regulatory approvals, if any, by delivery of shares of Common Stock of the Company already owned by, and in the possession of the stock option holder having a Fair Market Value equal to such stock option price, or any combination thereof. Shares of Common Stock used to satisfy the exercise price of a stock option shall be valued at their Fair Market Value determined as of the close of business on the date such stock option is exercised, or if such date is not a business day, on the business day immediately preceding the date of exercise. Deliveries of cash, shares and notices to the Company shall be directed to the Secretary of the Company.

No stock option granted hereunder shall be exercisable unless the Plan and all shares issuable on the exercise thereof have been registered under the Securities Act of 1933, as amended (the "1933 Act") and all other applicable securities laws, and there is available for delivery a prospectus meeting the requirements of Section 10 of the 1933 Act, or the Company shall have first received the opinion of its counsel that registration under the 1933 Act and all other applicable securities laws is not required in connection with such issuance. At the time of exercise, if the shares with respect to which the stock option is being exercised have not been registered under the 1933 Act and all other applicable securities laws, the Company may require the optionee to provide the Company whatever written assurance counsel for the Company may require that the shares are being acquired for investment and not with a view to the distribution thereof, and that the shares will not be disposed of without the written opinion of such counsel that registration under the 1933 Act and all other applicable securities laws is not required. Share certificates issued to the optionee upon exercise of the stock shall bear a legend to the foregoing effect to the extent counsel for the Company deems it advisable.

ARTICLE VIII
FAIR MARKET VALUE OF COMMON STOCK
For purposes of the Plan, the term "Fair Market Value" on any date shall mean
(i) if the Common Stock is listed or admitted to trade on a national securities exchange or national market system, the closing price of the Common Stock, as published in the Wall Street Journal, so listed or admitted to trade on such date or, if there is no trading of the Common Stock on such date, then the closing price of the Common Stock on the next preceding date on which there was trading in such shares; (ii) if the Common Stock is not listed or admitted to trade on a national securities exchange or national market system, the mean between the bid and asked price for the Common Stock on such date, as furnished

23

by the National Association of Securities Dealers, Inc. through NASDAQ or a similar organization if NASDAQ is no longer reporting such information, or (iii) if the Common Stock is not listed or admitted to trade on a national securities exchange and if bid and asked prices for the Common Stock are not so furnished through NASDAQ or a similar organization, the value established by the Board for purposes of the Plan. In addition to the above rules, Fair Market Value shall be determined without regard to any restriction other than a restriction which, by its terms, will never lapse

ARTICLE IX
WITHHOLDING TAX
Upon (i) the disposition by an employee or other person of shares of Common Stock acquired pursuant to the exercise of an incentive stock option granted pursuant to the Plan within two years of the granting of the incentive stock option or within one year after exercise of the incentive stock option, or (ii) the exercise of "non-incentive" or "non-qualified" stock options, the Company shall have the right to require such employee or such other person to pay the Company the amount of any taxes which the Company may be required to withhold with respect to such shares.

ARTICLE X
ADJUSTMENTS
Adjustments Upon Changes in Capitalization. Subject to any required action by the Company's directors and shareholders, the number of shares provided for in each outstanding stock option and the price per share thereof, and the number of share provided for in the Plan, shall be proportionately adjusted for any increase or decrease in the number of issued shares of the Company's Common Stock resulting from a subdivision or consolidation of shares or the payment of a stock dividend (but only on the Common Stock), a stock split, a reverse stock split, or any other increase or decrease in the number of such shares effected without receipt of consideration by the Company, and shall also be proportionately adjusted in the event of a spin-off, spin-out, or other distribution of assets to shareholders of the Company, to the extent necessary to prevent dilution of the interests of grantees pursuant to the Plan or of the other shareholders of the Company, as applicable. If the Company shall engage in a merger, consolidation, reorganization or recapitalization, each outstanding stock option (or if such transaction involves less than all of the shares of the Company's Common Stock, then a number of stock options proportionate to the number of such involved shares), shall become exercisable for the securities and other consideration to which a holder of the number of shares of the Company's Common Stock subject to each such stock option would have been entitled to receive in any such merger, consolidation reorganization or recapitalization.

Significant Event. In the event of a potential merger or consolidation involving the Company regardless of whether the Company is the surviving entity of such merger or consolidation, a potential liquidation or dissolution of the Company, a potential sale or other disposition by the Company of all or substantially all of its assets, or a potential sale or other disposition by the shareholders of the Company of all or substantially all of the outstanding Common Stock to one purchaser (any such merger, consolidation, liquidation, dissolution or sale being referred to herein as a "Significant Event"), then the Company shall have the option of terminating all outstanding stock options upon the actual occurrence of the Significant Event, by notice to all optionees at least 15 days before the occurrence of the Significant Event. In consideration for this option of the Company to terminate outstanding stock options, the Company, if it exercises its option, shall waive any and all restrictions on the vesting of optionees' rights under stock options granted pursuant to this Plan, and optionees' rights under their respective stock options shall vest in full, subject to the actual occurrence of the Significant Event. Any exercise by an optionee in these circumstances may be conditioned upon the occurrence of the Significant Event. If the Company exercises its option under this paragraph, upon the actual occurrence of the Significant Event, each outstanding stock option shall terminate. If the potential Significant Event does not in fact occur for any reason, then the Company's exercise of its option under this paragraph shall have no effect and the optionees' rights will be vested only to the extent that they would be vested if the Company had never exercised its option under this paragraph.

24

Change of Par Value. In the event of a change in the Company's Common Stock which is limited to a change of all of its authorized shares with par value into the same number of shares with a different par value or without par value, the shares resulting from any such change shall be deemed to be Common Stock within the meaning of the Plan.

Miscellaneous. The adjustments provided for in this Article shall be made by the Committee whose determination in that respect shall be final, binding and conclusive. Except as hereinbefore expressly provided in this Article, the holder of a stock option shall not be entitled to the privilege of stock ownership as to any shares of Common Stock or other stock not actually issued and delivered to the holder. Any issue by the Company of shares of stock of any class, or securities convertible into shares of stock of any class, shall not affect and no adjustment by reason thereof shall be made with respect to the number or price of shares of the Company's Common Stock subject to any stock option. The grant of a stock option pursuant to the Plan shall not affect in any way the right or power of the Company to, among other things, make adjustments, reclassifications, reorganizations or changes of its capital or business structure or to merge or to consolidate or to dissolve or liquidate or sell or transfer all or any part of its business or assets.

ARTICLE XI
PRIVILEGES OF STOCK OWNERSHIP
No person entitled to exercise any stock option granted under the Plan shall have any of the rights or privileges of a shareholder of the Company in respect of any shares of stock issuable upon exercise of such stock option until certificates representing such shares shall have been issued and delivered.

ARTICLE XII
ISSUANCE OF STOCK CERTIFICATES
Upon exercise of a stock option, the person exercising the stock option shall be entitled to one stock certificate evidencing the shares acquired upon such exercise; provided, however, that any person who tenders Common Stock of the Company in payment of a portion or all of the purchase price of Common Stock purchased upon exercise of the stock option shall be entitled to receive a separate certificate representing the number of shares purchased in consideration of the tender of such Common Stock.

ARTICLE XIII
CONTINUATION OF EMPLOYMENT
Nothing contained in the Plan (or in any stock option granted pursuant to the Plan) shall confer upon any employee any right to continue in the employ of the Company or any subsidiary corporation or constitute or any contract or agreement of employment or interfere in any way with the right of the Company or any subsidiary corporation to reduce any person's compensation from the rate in existence at the time of the granting of a stock option or to terminate such person's employment. Nothing contained herein or in any Agreement shall affect any other contractual rights of an employee.

ARTICLE XIV
AMENDMENT OR DISCONTINUANCE
The Board or the Committee may at any time and from time to time amend, rescind, suspend or terminate the Plan, as it shall deem advisable, provided that the Plan may not be amended in any manner which would cause the Plan to no longer comply with Rule 16b-3 of the General Rules and Regulations under the 1934 Act, or any successor rule, or the provision of the Code applicable to incentive stock options, as such rule or provision shall read as of the time of amendment. In addition to Board approval of any amendment to the Plan, if Rule 16b-3 of the General Rules and Regulations under the 1934 Act, or any successor rule, or the provisions of the Code applicable to incentive stock options, as such rule or

25

provision shall read as of the time of amendment, requires shareholder approval of such amendment, then such amendment shall be approved by the holders of a majority of the voting stock of the Company (voting as a single class) present, or represented, and entitled to vote at a meeting of such shareholders duly held in accordance with the applicable laws of this state or of the jurisdiction in which the Company is incorporated.

No change may be made in, and no amendment, rescission, suspension or termination of the Plan shall have an effect on, stock options previously granted under the Plan which may impair or alter the rights or obligations of the holders thereof, except that any change may be made in stock options previously granted with the consent of the optionees.

ARTICLE XV
EFFECTIVE DATE OF PLAN; SHAREHOLDER APPROVAL
The Plan shall be effective as of April 7, 2003, the date on which it received the approval of a majority of the disinterested members of the Board. However, the Plan and all stock options granted under the Plan (but not the previous Amended and Restated 1992 Stock Option Plan of the Company) shall be void if the Plan is not approved by the shareholders within 12 months from the date the Plan is approved by the Board in which case, the previous Amended and Restated 1992 Stock Option Plan of the Company shall remain in full force and effect. The Plan shall be deemed approved by the holders of the outstanding voting stock of the Company by the affirmative votes of the holders of a majority of the outstanding voting stock of the Company present, or represented, and entitled to vote at a meeting duly held in accordance with the applicable laws of the state or other jurisdiction in which the Company is incorporated. Any stock options granted under the Plan (but not the previous Amended and Restated 1992 Stock Option Plan of the Company) prior to obtaining such shareholder approval shall be granted under the conditions that the stock options so granted (1) shall not be exercisable prior to such shareholder approval, and (2) shall become null and void if such shareholder approval is not obtained.
