REPORT OF THE COMPENSATION AND INCENTIVE STOCK OPTION COMMITTEEReport of the Compensation and Incentive Stock Option Committee

Peter T. Kissinger, Candice B. Kissinger John A. Kraeutler and William E. Baitinger serve on the Compensation Committee. The Compensation Committee has responsibility for BASi'sthe administration of BASi’s executive Compensation Program.compensation program. Dr. Kissinger, the President and Chief Executive Officer of BASi, does not participate in decisions regarding his compensation. None of BASi'sBASi’s executive officers serves as a director of, or in any compensation-related capacity for, companies with which members of the Compensation Committee are affiliated.

The following report is submitted by the members of the Compensation Committee.Committee:

BASi'sBASi’s executive compensation program is designed to align executive compensation with financial performance, business strategies and Companythe values and objectives. BASi'sobjectives of BASi. BASi’s compensation philosophy is to ensure that the delivery of compensation, both in the short and long term, is consistent with the sustained progress, growth and profitability of BASi and acts as an inducement to attract and retain qualified individuals. This program seeks to enhance the profitability of BASi, and thereby enhance shareholder value, by linking the financial interests of BASi'sBASi’s executives with those of its long-term shareholders. Under the guidance of BASi'sBASi’s Compensation Committee, BASi has developed and implemented an executive compensation program to achieve these objectives while providing executives with compensation opportunities that are competitive with companies of comparable size in related industries.




BASi's11

BASi’s executive compensation program has been designed to implement the objectives described above and is comprised of the following fundamental elements:

A base salary that is determined by individual contributions and sustained performance within an established competitive salary range. Pay for performance recognizes the achievement of financial goals, accomplishment of corporate and functional objectives, and performance of individual business units of BASi.

Grants of options under BASi'sBASi’s option plans reward executives when shareholder value is created through increase in the market value of BASi'sBASi’s common shares. Stock option grants focus executives on managing BASi from the perspective of an owner with an equity position in the business.

Base Salary. The salary, and any periodic increase thereof, of the President and Chief Executive Officer were and are determined by the Board of Directors of BASi based on recommendations made by the Compensation Committee, excluding Dr. Kissinger. The salaries, and any periodic increases thereof, of all other executive officers were and are also determined by the Board of Directors based on Committee recommendations.

BASi, in establishing base salaries, levels of incidental and/or supplemental compensation, and incentive compensation programs for its officers and key executives, assesses periodic compensation surveys and published data covering both the BASi industry and other industries. The level of base salary compensation for officers and key executives is determined by both the scope of their responsibility and the salary ranges for officers and key executives of BASi established by the Board of Directors and the Compensation Committee. Periodic increases in base salary are dependent on the executive'sexecutive’s proficiency of performance in the individual'sindividual’s position for a given period and on the executive'sexecutive’s competency, skill and experience.

Due toOn his own initiative the salary freeze implemented by the Board of Directors,fiscal 2003 compensation levels for fiscal 2002level for the President and Chief Executive Officer was significantly reduced and redistributed to select BASi staff. Dr. Kissinger has expressed his intention to stay at this compensation level until BASi’s financial performance improves. Base salary increases for other eligible BASi staff were distributed in the other Executive Officersfirst fiscal quarter of 2004.

Bonus.        In years in which the after-tax net income of BASi did not increase.exceeds 7% of revenue, the Compensation Committee is authorized to award bonuses to any BASi employee at the Committee’s discretion.

Option Plans.        Granting of options pursuant to BASi’s option plans is intended to align executive interest with the long-term interests of shareholders by linking executive compensation with enhancement of shareholder value. In addition, grants of options motivate executives to improve long-term stock market performance by allowing them to develop and maintain a significant long-term equity ownership position in BASi’s common shares. No options were granted to executives or staff in fiscal 2002.2003.

2.    APPROVAL OF AMENDMENT TO THE 1997 EMPLOYEE INCENTIVE STOCK OPTION PLAN

On October 23, 1997,Communications with the Board of Directors

Currently, BASi shareholders may send communications directly to Peter T. Kissinger, Chairman of BASi adopted the Employee Option Plan, which was subsequently approved by the shareholders of BASi prior to the initial public offering. On January 24, 2003, the BASi Board of Directors, approved an amendment tounder the Employee Option Plan, described below, subject to approval by the shareholders of BASi.

The principal features“Ask Pete” portion of the Employee Option Plan, including an explanation of the material change contemplated by the proposed amendment, are described below, but such description is qualified entirely by reference to the text of the Employee Option Plan, a copy of which is attached to this Proxy Statement as Appendix A. Except as otherwise described below in the explanation of the proposed amendment, all other existing provisions of the Employee Option Plan are not changed.

PROPOSED PLAN AMENDMENT; INCREASE IN AUTHORIZED SHARES

As of December 31, 2002, 10,250 common shares remained available for additional option grants under the Employee Option Plan.BASi website found athttp://www.bioanalytical.com/. The Board of Directors amended the Employee Option Plan, subject to shareholder approval, to increase the number of shares available for issuance under the Employee Option Plan. Because of historic grant patterns and expansion plans for the company, the Board of Directors believe the number of shares presently available for grant and those which may become availableis also in the future will not give BASi sufficient flexibilityprocess of implementing a shareholder communication policy in order to structure future incentives. Therefore, ifbetter facilitate communications between shareholders approve the proposed amendment, an additional 300,000 shares would become available for grants under the Employee Option Plan.

SUMMARY OF THE EMPLOYEE OPTION PLAN

General.     The purpose of the Employee Option Plan is to further the growth, development and financial success of BASi by providing additional incentives to certain eligible employees and permitting those persons to benefit directly from the growth, development and financial success of BASi.

Administration.    The Employee Option Plan is administered by an Incentive Stock Option Committee consisting of three (3) or moreall members of the Board of Directors of BASi (the “Employee Committee”). The Employee Committee has the authority to interpret and construe the provisions of the Employee Option Plan or any option granted under it, determine exercise periods, and prescribe, amend and rescind rules and regulations with regard to the Employee Option Plan.

Eligibility.    Options under the Employee Option Plan may be granted only to those persons who are employees of BASi and who are eligible to participate. Eligibility shall be determined by the Employee Committee from time to time; provided that no option shall be granted to any employee of BASi who, at the time such option is granted, owns shares (together with such person’s brothers, sisters, spouse, ancestors and lineal descendants) possessing more than ten percent (10%) of the total combined voting power of all classes of shares of BASi or any parent or subsidiary of BASi (a “10% Shareholder”). The percentage limitations do not apply if at the time such option is granted the option price is at least one hundred ten percent (110%) of the fair market value of the shares subject to the option and such option is not exercisable after the expiration of five (5) years from the date such option is granted.

Maximum Number of Shares.    As amended by the Board of Directors of BASi, subject to approval by the shareholders of BASi, the aggregate number of shares for which options may be granted under the Employee Option Plan is 395,000, subject to adjustments for recapitalizations. Any shares subject to an option that expires or is terminated shall again become available for grant. Prior to the amendment by the Board of Directors of BASi, the aggregate number of shares for which options could be granted under the Employee Option Plan was 95,000, subject to adjustments for recapitalizations.

Maximum Exercise Rule.    The Employee Option Plan limits the aggregate fair market value (determined at the time the option is granted) of the shares with respect to which incentive stock options are exercisable for the first time during any calendar year to $100,000.

Exercise Price.    Any grant of options under the Employee Option Plan shall have an exercise price of not less than the fair market value per share of the shares on the date of granting of the option. The exercise price of an option granted under the Employee Option Plan may be paid (i) in cash, (ii) by certified check or bank cashier’s check, (iii) through the tender to BASi of shares of BASi or through the withholding of shares of BASi that are subject to the option, or (iv) by a combination of the foregoing; provided that the Employee Committee may impose limitations on the use of shares to exercise options. Any grant of options under the Employee Option Plan to a 10% Shareholder in an amount per share not less than one hundred ten percent (110%) of the fair market value per share of the shares on the date of the granting of the option.

Term of Options.    No term of any option granted under the Employee Option Plan shall be in excess of ten (10) years; provided, however, if the person to whom the option is granted is a 10% Shareholder, the term shall not be longer than five (5) years.

Termination of Employment.    Upon cessation of employment with BASi or certain entities affiliated with BASi, all options granted under the Employee Option Plan held by such employee shall terminate as to any unexercised portion thereof; provided, however, that if the cessation of employment is due to retirement with the consent of BASi such employee may exercise any such options within three (3) months after such cessation and if the cessation of employment is due to permanent or total disability or death such employee or such employee’s personal representative, as the case may be, may exercise any such options within 12 months after such cessation of employment.

Merger, Dissolution or Liquidation.    Upon merger or consolidation, BASi may terminate any option outstanding on 30 days written notice. Upon dissolution or liquidation of BASi, BASi shall provide 30 days written notice to all holders of options and each unexercised option shall terminate upon dissolution or liquidation.

Assignability.    Options may not be assigned or transferred, except by will or by the laws of descent and distribution, and during an optionee’s lifetime may be exercised only by the optionee.

Term of the Employee Option Plan.    The Employee Option Plan may be terminated by the Board of Directors of BASi at any time with respect to shares as to which options have not been granted. No options may be granted under the plan after its termination.

Amendment.    The Board of Directors of BASi may amend, suspend or discontinue the Employee Option Plan with respect to any shares as to which options have not been granted. The approval of the holders of a majority of the outstanding shares of each class of voting shares of BASi is required for any amendment to the Employee Option Plan relating to (i) an increase in the number of shares for which options may be granted, (ii) a change in the class of shares for which options may be granted, and (iii) a change in the manner in which the option price is determined.

Withholdings.    The Employee Committee has the right to require persons receiving options to remit to BASi amounts sufficient to satisfy any federal, state or local income tax withholding requirements.

FEDERAL INCOME TAX CONSEQUENCES

The federal income tax consequences of an employee's participation in the Employee Option Plan are complex and subject to change. The following discussion is only a summary of the general rules applicable to stock options granted under the Employee Option Plan as of the date hereof. The application of state and local income taxes and other federal taxes is not discussed. For individuals resident outside the United States, the tax consequences to the individual and to BASi are determined by the applicable tax laws of the foreign jurisdiction.

The grant of an incentive stock option under the Employee Option Plan generally will have no federal income tax consequences for BASi or the optionee. Except for alternative minimum tax purposes, the exercise of an incentive stock option pursuant to the Employee Option Plan will have no federal income tax consequences to BASi or the optionee. An optionee generally will recognize capital gain or loss upon the sale of shares acquired in exercising an incentive stock option, provided that the shares are sold at least two years after the date of grant of the option and at least one year after the optionee acquires the shares. An optionee generally will recognize ordinary income upon the sale of shares acquired in exercising an incentive stock option if the sale is made within two years of the date the option was granted or within one year of the date the shares were transferred to the optionee. In such event, the amount of ordinary income recognized by the optionee generally will equal the difference between the option price and the fair market value of the shares on the date of exercise. BASi may take an income tax deduction for compensation conveyed by an incentive stock option only in situations (and the taxable year) in which the employee must recognize ordinary income.

Furthermore, if the compensation attributable to awards is not "performance-based" within the meaning of Section 162(m) of the Internal Revenue Code, BASi may not be permitted to deduct the aggregate non performance-based compensation in excess of $1,000,000 in certain circumstances.

VOTE REQUIRED

The approval of the amendment to the Employee Option Plan requires the affirmative vote of the holders of a majority of the outstanding common shares.

The Board of Directors of BASi recommends a vote FOR the approval of the amendment to the Employee Option Plan.

NEW PLAN BENEFITS

BASi currently anticipates that it will, as a general matter, grant options on an annual basis. However, future option grant recipients, and future option grant levels, have not been determined. Therefore, the number, amount and type of awards to be received by or allocated to eligible persons in the future under the Employee Option Plan cannot be determined at this time. BASi has not approved any awards under the Employee Option Plan that are conditioned upon shareholder approval of the proposed plan amendment. On January 20, 2003, the closing price of a common share of BASi was $3.52.

3.    APPROVAL OF THE 1997 OUTSIDE DIRECTOR STOCK OPTION PLAN, AS AMENDED

On October 23, 1997, the Board of Directors of BASi adopted the Director Option Plan. On January 24, 2003, the Board of Directors of BASi approved an amendment to the Director Option Plan to increase the number of shares for which options can be granted from 5,000 to 30,000. The Board of Directors is seeking approval of the Director Option Plan, as amended.

Eligibility.    Options under the Director Option Plan may be granted only to persons who are outside directors of BASi. Eligibility shall be determined by the Director Committee from time to time.

Maximum Number of Shares.    As amended by the Board of Directors of BASi, the aggregate number of shares for which options may be granted under the Director Option Plan is 30,000, subject to adjustments for recapitalizations. Any shares subject to an option that expires or is terminated shall again become available for grant. Prior to the amendment by the Board of Directors of BASi, the aggregate number of shares for which options could be granted under the Director Option Plan was 5,000, subject to adjustments for recapitalizations.

Exercise Price.    Any grant of options under the Director Option Plan shall have an exercise price of not less than the fair market value per share of the shares on the date of granting of the option. The exercise price of an option granted under the Director Option Plan may be paid (i) in cash, (ii) by certified check or bank cashier's check, (iii) through the tender to BASi of shares of BASi or through the withholding of shares of BASi that are subject to the option, or (iv) by a combination of the foregoing; provided that the Director Committee may impose limitations on the use of shares to exercise options.

Term of Options and Time of Exercise.    No term of any option granted under the Director Option Plan shall be in excess of ten (10) years. Each option granted under the Director Option Plan shall be exercisable in four (4) equal installments. The option may be exercised as to the shares covered by the first installment from and after the second anniversary of the grant of the option, with second, third and fourth installments becoming exercisable on the three (3) succeeding anniversary dates; provided that any such limitation on the exercise of an option may be rescinded, modified or waived by the Director Committee.

Termination of Service as a Director.    In the event an individual ceases to serve as a director of BASi or of any one of certain entities affiliated with BASi, all options granted under the Director Option Plan held by such individual shall terminate as to any unexercised portion thereof; provided that if the cessation of service is due to retirement with the consent of BASi such individual may exercise any such options within three (3) months after such cessation and if the cessation of service is due to permanent or total disability or death such individual or such individual's personal representative, as the case may be, may exercise any such options within 12 months after such cessation of service.

Adjustments upon Merger or Dissolution.    Upon merger or consolidation, BASi may terminate any option outstanding on 30 days written notice. Upon dissolution or liquidation of BASi, BASi shall provide 30 days written notice to all holders of options and each unexercised option shall terminate upon dissolution or liquidation.

Assignability.    Options may not be assigned or transferred except by will or by the laws of descent and distribution and during an optionee's lifetime may be exercised only by the optionee.

Term of the Director Option Plan.    Options may be granted under the Director Option Plan until the ten (10) year anniversary of the adoption of the Director Option Plan.

Amendment.    The Board of Directors of BASi may amend, suspend or discontinue the Director Option Plan with respect to any shares as to which options have not been granted. The approval of the holders of the options under the Director Option Plan is required for any amendment to the Director Option Plan that would alter any of the rights or obligations of BASi or any holder of options with respect to the outstanding option.

Withholdings.    The Director Committee has the right to require persons receiving options to remit to BASi amounts sufficient to satisfy any federal, state or local income tax withholding requirements.

FEDERAL INCOME TAX CONSEQUENCES

The holder of an option will not be subject to tax at the time a nonqualified option is granted; however, a director who exercises a nonqualified option must include in income as of the date of exercise the difference between (i) the amount paid for the shares upon exercise of the option and (ii) the fair market value of the shares. The recognized income may be subject to withholding for federal, state and local income and other payroll taxes. The optionee's federal income tax cost basis for the shares will be the amount paid for the shares plus the income recognized. If an optionee uses shares in full or partial payment of the exercise price of a nonqualified option, the exchange should not affect the federal income tax treatment of the exercise. The optionee will realize no gain or loss with respect to the shares so used. The net additional shares received upon such exercise by the optionee will have a federal income tax cost basis equal to the ordinary income recognized as a result of the option exercise (plus the amount of any cash used in the option exercise) and a holding period commencing upon the date such income is recognized. Subsequent sale of such shares will result in a capital gain or loss equal to the difference between the optionee's federal income tax cost basis for the shares and the sale price.

BASi will be entitled to a federal income tax deduction in the amount of the ordinary income recognized by the optionee as of the date the optionee recognizes ordinary income.

VOTE REQUIRED

The approval of the Director Option Plan requires that the votes cast for approval of the Director Option Plan by the shareholders of BASi exceed those case against approval of the Director Option Plan by the shareholders of BASi.

The Board of Directors of BASi recommends a vote FOR the approval of the Director Option Plan.

NEW PLAN BENEFITS

The following table sets forth certain information regarding the benefits expected to be received by persons in each indicated group under the Director Option Plan, as amended. The original 5,000 shares authorized by the Director Option Plan were available for grants only to non-executive directors of BASi.

APPENDIX A

BIOANALYTICAL SYSTEMS, INC.
1997 EMPLOYEE INCENTIVE STOCK OPTION PLAN
(As Amended January 24, 2003)

1.    Purpose.    This 1997 Employee Incentive Stock Option Plan (hereinafter referred to as the "Plan") is intended to be an incentive to, and to encourage share ownership by, key employees of Bioanalytical Systems, Inc. and its subsidiaries (hereinafter collectively referred to as the "Employer") in the manner contemplated by Section 422 of the Internal Revenue Code of 1986, as amended ("Code"), in order to provide such employees with a more direct and proprietary interest in the welfare and success of the Employer and to insure their continuation as employees of the Employer.

2.    Administration.    The Plan shall be administered by an Incentive Stock Option Committee (hereinafter referred to as the "Committee") consisting of three (3) or more members of the Board of Directors, of Bioanalytical Systems, Inc. (the "Company") who are appointed from time to time by the Board of Directors of the Company. The Board of Directors of the Company may from time to time remove members from, or add members to, the Committee. Vacancies on the Committee, howsoever caused, shall be filled by the Board of Directors of the Company. The Committee shall have the power to interpret and construe the provisions of the Plan or any option granted under it, and such interpretation or construction shall be final and binding. The Committee may prescribe, amend and rescind rules and regulations relative to the Plan or its construction or interpretation. A majority of the Committee shall constitute a quorum. All determinations of the Committee shall be made by not less than a majority of its members. No member of the Committee shall be liable for any action or determination made in good faith.

3.    Eligibility.    Only those persons who are employees of the Employer shall be eligible to participate in the Plan. The Committee shall determine from time to time the particular employees of the Employer who shall be eligible to participate in the Plan and the extent of their participation therein. No option shall be granted under the Plan to any employee of the Employer who, at the time such option is granted, owns shares possessing more than ten percent (10%) of the total combined voting power of all classes of shares of the Company or of any parent or subsidiary corporation of the Company or any parent or subsidiary corporation of any of the foregoing (such employee being hereinafter referred to as a "10% Shareholder"), except as provided below. In determining whether the percentage limitations of this paragraph are met, an employee shall be considered as owning any shares owned, directly or indirectly, by or for his brothers or sisters (whether by the whole or half blood), spouse, ancestors, and lineal descendants. For purposes of this paragraph 3, shares owned, directly or indirectly, by or for a corporation, partnership, estate, or trust shall be considered as being owned proportionately by or for its shareholders, partners, or beneficiaries. The percentage limitations of this paragraph 3 shall not apply, however, if at the time such option is granted the option price is at least one hundred ten percent (110%) of the fair market value of the shares subject to the option and such option by its terms is not exercisable after the expiration of five (5)years from the date such option is granted.

4.    Shares.    The shares subject to the options and other provisions of the Plan shall be shares of the Company's authorized, but unissued, or reacquired Common Shares (the "Common Shares"). The total amount of the Common Shares on which options may be granted shall not exceed in the aggregate Three Hundred Ninety-Five Thousand (395,000) shares, except as such number of shares shall be adjusted in accordance with the provisions set forth in paragraph 6(g) hereof. In the event any outstanding option under the Plan expires or is terminated for any reason prior to the end of the period during which options may be granted, the Common Shares allocable to the unexercised portion of such option may again be subject to an option under the Plan. During the period that any options granted hereunder are outstanding, the Employer shall reserve and keep available such number of Common Shares as will be sufficient to satisfy all outstanding, unexercised options.

5.    Maximum Exercise Rule.     The aggregate fair market value (determined at the time the option is granted) of the shares with respect to which incentive stock options are exercisable for the first time by an employee during any calendar year under all such plans of the Employer and any parent or subsidiary corporation of the Employer shall not exceed One Hundred Thousand Dollars ($100,000.00).

6.    Terms and Conditions of Options.     Options granted pursuant to the Plan shall be evidenced by agreements in such form as the Committee shall from time to time prescribe, which agreements shall comply with and be subject to the following terms and conditions:

(a)
Medium and Time of Payment.    The option price shall be payable in United States dollars upon the exercise of the option and shall be paid (i) in cash; (ii) by certified check or by bank cashier's check; (iii) through the tender to the Company of Common Shares of the Company or through the withholding of Common Shares of the Company that are subject to the option, which Common Shares shall be valued, for purposes of determining the extent to which the purchase price has been paid, at their fair market value on the date of exercise as determined in Section 6(c); or (iv) by a combination of the methods described in (i), (ii), or (iii); provided, however, that the Committee may in its discretion impose and set forth in the option agreement pertaining to an option such limitations or prohibitions on the use of Common Shares to exercise options as it deems appropriate. Fair market value of the Common Shares shall be determined by the Committee in the same manner that it is determined in establishing option prices. Payment of the option price shall be accompanied by a written subscription agreement in a form to be prescribed by the Committee.
(b)
Number of Shares.     The option agreement shall state the total number of shares to which it pertains, and the date of the grant of the option. The Committee may prescribe in the option agreement a minimum number of Common Shares with respect to which an option may be exercised, in whole or in part.
(c)
Option Price.     The option price shall be an amount per share not less than the fair market value per share of the Common Shares on the date of granting of the option. In the case of options granted to an employee of the Employer who is a 10% Shareholder, the option price shall be an amount per share not less than one hundred ten percent (110%) of the fair market value per share of the Common Shares on the date of the granting of the option. Fair market value shall mean, if the price of the Common Shares is so reported, the closing price for the Common Shares on the National Association of Securities Dealers Automated Quotation System or any exchange on which the Common Shares are then traded, as reported in The Wall Street Journal (Midwest Edition). If the price of Common Shares is not so reported, fair market value shall be determined, in good faith, by the Committee in accordance with such procedures as the Committee shall from time to time prescribe.
(d)
Term of Option.     The term of each option granted under the Plan shall expire within the period prescribed in the agreement relating thereto, which shall not be more than five (5) years from the date the option is granted if the optionee is a 10% Shareholder and not more than ten (10) years from the date the option is granted if the optionee is not a 10% Shareholder.
(e)
Date of Exercise.     Each option shall be exercisable as determined by the Committee and set forth in an option agreement, provided, however, that any such limitation on the exercise of an option contained in an option agreement may be rescinded, modified, or waived by the Committee, in its sole discretion, at any time and from time to time after the date of grant of such option so as to accelerate the time in which the option may be exercised. Except as specifically restricted by the Committee, any option may be exercised in whole at any time or in part from time to time during its term.
(f)
Termination of Employment.     In the event an optionee shall cease to be employed by the Employer, a parent corporation of the Employer, or a corporation or a parent or a subsidiary corporation of such corporation issuing or assuming an option in a transaction to which Section 424(g) of the Code applies, all options outstanding in the hands of the optionee shall terminate immediately as to any unexercised portion thereof; provided, however, that if any cessation of employment is due to retirement with the consent of the Employer or permanent and total disability, the optionee shall have the right, subject to the provisions of paragraph 6(d) and paragraph 6(e) hereof, to exercise the option, with respect to the shares for which it could have been exercised on the effective date of his cessation of employment, at any time within three (3) months after such cessation of employment due to retirement with the consent of the Employer or at any time within twelve (12) months after such cessation of employment due to permanent and total disability; and provided further, that if the employee shall die while in the employ of the Employer, the employee's personal representative shall have the right, subject to the provisions of paragraph 6(d) and paragraph 6(e) hereof, to exercise the option with respect to the shares for which it could have been exercised on the date of death, at any time within twelve (12) months from the date of death. Whether a cessation of employment is to be considered a retirement with the consent of the Employer or due to permanent and total disability, and whether an authorized leave of absence or absence on military or government service shall be deemed to constitute termination of employment, for the purposes of the Plan, shall be determined by the Committee, which determination shall be final and conclusive.
(g)
Recapitalization.     The aggregate number of Common Shares on which options may be granted hereunder, the number of shares thereof covered by each outstanding option, and the price per share thereof in each such option, shall all be proportionately adjusted for any increase or decrease in the number of issued Common Shares resulting from a subdivision or consolidation of shares or any other capital adjustment, the payment of a share dividend, or other increase or decrease in the Common Shares effected without receipt of consideration by the Employer. In the event that, prior to the delivery by the Employer of the Common Shares remaining under any outstanding option hereunder, there shall be a capital reorganization or reclassification of the capital of the Employer resulting in a substitution of other shares for the Common Shares, there shall be substituted the number of substitute shares which would have been issued in exchange for the Common Shares then remaining under the option if such Common Shares had been then issued and outstanding.
(h)
Merger, Dissolution.     If the Employer shall be a party to any merger or consolidation, the Employer shall have the right to terminate any option outstanding on thirty (30) days written notice; provided, however, if such merger or consolidation is not consummated within 180 days from the date of the aforementioned notice, all options terminated shall be deemed to have been continuously in effect since the date of execution thereof. In the event of a dissolution or liquidation of the Employer, the Employer shall give each optionee thirty (30) days written notice thereof; every unexercised option outstanding hereunder shall be deemed to be terminated upon such dissolution or liquidation.
(i)
Assignability.     No option shall be assignable or transferable except by will or under the laws of descent and distribution. During the lifetime of an optionee, the option shall be exercisable only by the optionee.
(j)
Issuance of Shares and Compliance with Securities Laws.     The Employer may postpone the issuance and delivery of certificates representing shares until (a) the admission of such shares to listing on any stock exchange on which shares of the Employer of the same class are then listed and (b) the completion of such registration or other qualification of such shares under any state or federal law, rule or regulation as the Employer shall determine to be necessary or advisable, which registration or other qualification the Employer shall use its best efforts to complete; provided, however, a person purchasing shares pursuant to the Plan has no right to require the Employer to register the Common Shares under federal or state securities laws at any time. Any person purchasing shares pursuant to the Plan may be required to make such representations and furnish such information as may, in the opinion of counsel for the Employer, be appropriate to permit the Employer, in light of the existence or non-existence with respect to such shares of an effective registration under the Securities Act of 1933, as amended, or any similar state statute, to issue the shares in compliance with the provisions of those or any comparable acts.
(k)
Rights as a Shareholder.     An optionee shall have no rights as a shareholder with respect to shares covered by an option until the date of issuance of a certificate to him and only after such shares are fully paid. No adjustment will be made for dividends or other rights for which the record date is prior to the date such certificate is issued.
(l)
Other Provisions.     The option agreements entered into under the Plan shall contain such other provisions as the committee shall deem advisable.

7.    Term of Plan.     The Plan shall become effective upon the approval by the holders of a majority of the issued and outstanding shares of each class of the voting shares of the Company voting in person or by proxy at a duly held shareholders' meeting; provided, however, that the Plan shall become effective only if approved by such shareholders within twelve (12) months before or after the date the Plan is adopted by the Company Board of Directors. The Board of Directors may, in its sole discretion, terminate the Plan at any time with respect to any shares as to which options have not been granted. No option shall be granted under the Plan thereafter.

8.    Amendment of the Plan.     The Board of Directors of the Company may from time to time, alter, amend, suspend, or discontinue the Plan with respect to any shares as to which options have not been granted; provided, however, that the Board of Directors may not, without further approval by the holders of a majority of the issued and outstanding shares of each class of voting shares of the Company:

(a)increase the maximum number of shares as to which options may be granted under the Plan (other than to reflect a stock split or stock dividend);
(b)change the class of shares for which options may be granted under the Plan; or
(c)change the provisions of paragraph 6(c) concerning the option price.

9.    Application of Funds.     The proceeds received by the Company from the sale of shares pursuant to options granted hereunder will be used for general corporate purposes.

10.    No Obligation to Exercise Option.     The granting of an option hereunder shall impose no obligation upon the optionee to exercise such an option.

11.    Continuance of Employment.     Neither the adoption of the Plan nor the granting of an option hereunder shall impose any obligation on the Employer to continue the employment of an optionee.

12.    Applicability of Amendments.     All outstanding options shall be deemed to be amended so as to include, to the extent applicable thereto, any amendments made to the Plan subsequent to the granting of such options.

13.    Withholdings.    The Committee shall have the right to require optionees to remit to the Company amounts sufficient to satisfy any federal, state or local income tax withholding requirements (or make other arrangements satisfactory to the Company with regard to such taxes) at such times as the Company deems necessary or appropriate for compliance with such laws.

Any person purchasing Common Shares pursuant to the Plan may be required to make such representations and furnish such information as may, in the opinion of counsel for the Company, be appropriate to permit the Company, in light of the existence or non-existence with respect to such shares of an effective registration under the Securities Act of 1933, as amended, or any similar state statute, to issue the shares in compliance with the provisions of those or any comparable acts.
(k)
Rights as a Shareholder.    An Optionee shall have no rights as a shareholder with respect to Common Shares covered by an option until the date of issuance of a certificate to the Optionee.

No adjustment will be made for dividends or other rights for which the record date is prior to the date such certificate is issued.

Other Provisions.    The option agreements entered into under the Plan shall contain such other provisions, limitations, restrictions and requirements as the Committee shall deem advisable.

7.    Term of the Plan.    The Plan shall become effective upon the date the Plan is adopted by the Board of Directors. The Plan shall terminate ten (10) years after the date the Plan is adopted by the Board of Directors, or on such earlier date as the Board of Directors may determine. No option shall be granted under the Plan after such termination date.

8.    Amendment of the Plan.    The Board of Directors may from time to time, alter, amend, suspend, or discontinue the Plan with respect to any Common Shares as to which options have not been granted; provided, however, that no action may be taken hereunder which would alter or impair any of the rights or obligations of the Company or any Optionee with respect to any outstanding option without the consent of the Optionee thereof.

9.    Application of Funds.     The proceeds received by the Company from the sale of Common Shares pursuant to options granted hereunder will be used for general corporate purposes.

10.    No Obligation to Exercise Option.    The granting of an option hereunder shall impose no obligation upon the Optionee to exercise such an option.

11.    No Right to Reelection.    Neither the adoption of the Plan, the granting of an option hereunder, nor any other action taken relating to the Plan shall impose any obligation on the Company or any Affiliate or the Board of Directors of either to nominate any Outside Director for reelection as a director by the shareholders of the Company or any Affiliate.

12.    Applicability of Amendments.    All outstanding options shall be deemed to be amended so as to include, to the extent applicable thereto, any amendments made to the Plan subsequent to the granting of such options.

13.    Withholdings.     The Committee shall have the right to require the Optionee to remit to the Company amounts sufficient to satisfy any applicable withholding requirements set forth in the Code or under state or local law relating to options granted to the Optionee. The Company shall have the right, to the extent permitted by law, to deduct from any payment of any kind otherwise due to an Optionee who exercises an option any federal, state or local taxes of any kind required by law to be withheld with respect to the Common Shares subject to such option.
