QUALIFIED INCENTIVE OPTIONS It is intended that Options granted under this Section 8 shall be qualified incentive stock options under the provisions of Section 422 of the Code and the regulations thereunder or corresponding provisions of subsequent revenue laws and regulations in effect at the time such Options are granted. Such Options shall be evidenced by stock option agreements in such form and not inconsistent with this Plan as the Committee or the Board of Directors shall approve from time to time, which Agreements shall contain in substance the following terms and conditions: (a) Price. The purchase price for shares purchased upon exercise will be ----- equal to 100% of the Market Price on the day the Option is granted, as determined by the Board of Directors or the Committee; provided that the purchase price of stock deliverable upon the exercise of a qualified incentive option granted to a Ten Percent Owner shall be not less than one hundred ten percent (110%) of the Market Price on the day the Option is granted, as determined by the Board of Directors or the Committee, but in no case less than the par value of such stock. 5 (b) Number of Shares. The Agreement shall specify the number of Shares ----------------- which the Optionee may purchase under such Option. (c) Exercise of Options. The shares subject to the Option may be ------------------- purchased in whole or in part by the Optionee in accordance with the terms of the Agreement, from time to time after shareholder approval of the Plan, but in no event later than ten (10) years from the date of grant of the Option. Notwithstanding the foregoing, Shares subject to an Option granted to a Ten Percent Owner shall be exercisable no later than five (5) years from the date of grant of the Option. (d) Medium and Time of Payment. Stock purchased pursuant to an Agreement --------------------------- shall be paid for in full at the time of purchase. Payment of the purchase price shall be in cash or shares of the Common Stock of the Company, or a combination of cash and shares of the Common Stock of the Company, in the discretion of, and as authorized by, the Committee. Upon receipt of payment, the Company shall, without transfer or issue tax, deliver to the Optionee (or other person entitled to exercise the Option) a certificate or certificates for such Shares. (e) Rights as a Shareholder. An Optionee shall have no rights as a ------------------------ shareholder with respect to any Shares covered by an Option until the date of issuance of the stock certificate to the Optionee for such Shares. Except as otherwise expressly provided in the Plan, no adjustments shall be made for dividends (ordinary or extraordinary, whether in cash, securities or other property) or distributions or other rights for which the record date is prior to the date such stock certificate is issued. (f) Nonassignability of Option. No Option shall be assignable or --------------------------- transferable by the Optionee except by will or by the laws of descent and distribution. During the lifetime of the Optionee, the Option shall be exercisable only by him or her. (g) Effect of Termination of Employment or Death. In the event that an --------------------------------------------- Optionee during his or her lifetime ceases to be an employee of the Company or of any subsidiary of the Company for any reason (including retirement) other than death or permanent and total disability, any Option or unexercised portion thereof which was otherwise exercisable on the date of termination of employment shall expire unless exercised within a period of three (3) months from the date on which the Optionee ceased to be an employee, but in no event after the term provided in the Optionee's Agreement. In the event that an Optionee ceases to be an employee of the Company or of any subsidiary of the Company for any reason (including retirement) other than death or permanent and total disability prior to the time that an Option or portion thereof becomes exercisable, such Option or portion thereof which is not then exercisable shall terminate and be null and void. Whether authorized leave of absence for military or government service shall constitute termination of employment for the purpose of this Plan shall be determined by the Board of Directors or the Committee, which determination shall be final and conclusive. In the event that an Optionee during his or her lifetime ceases to be an employee of the Company or any subsidiary of the Company by reason of death or permanent and total disability, any Option or unexercised portion thereof which was otherwise exercisable on the date such Optionee ceased employment shall expire unless exercised within a period of one (1) year from the date on which the Optionee ceased to be an employee, but in no event after the term provided in the Optionee's Agreement. In the event that an Optionee during his or her lifetime ceases to be an employee of the Company or any subsidiary of the Company by reason of death or permanent and total disability, any Option or portion thereof which was not exercisable on the date such Optionee ceased employment shall become immediately exercisable for a period of one (1) year from the date on which the Optionee ceased to be an employee, but in no event after the term provided in the Optionee's Agreement. 6 "Permanent and total disability" as used in this Plan shall be as defined in Section 22(e)(3) of the Code. In the event of the death of an Optionee, the Option shall be exercisable by his or her personal representatives, heirs or legatees, as provided herein. (h) Recapitalization. In the event that dividends are payable in Common ----------------- Stock of the Company or in the event there are splits, subdivisions or combinations of shares of Common Stock of the Company, the number of Shares available under the Plan shall be increased or decreased proportionately, as the case may be, and the number and Option exercise price of Shares deliverable upon the exercise thereafter of any Option theretofore granted shall be increased or decreased proportionately, as the case may be, as determined to be proper and appropriate by the Board of Directors or the Committee. (i) Reorganization. In case the Company is merged or consolidated with --------------- another corporation and the Company is not the surviving corporation, or in case the property or stock of the Company is acquired by another corporation, or in case of a separation, reorganization, recapitalization or liquidation of the Company, the Board of Directors of the Company, or the Board of Directors of any corporation assuming the obligations of the Company hereunder, shall either (i) make appropriate provision for the protection of any outstanding Options by the substitution on an equitable basis of appropriate stock of the Company, or of the merged, consolidated or otherwise reorganized corporation which will be issuable in respect to the shares of Common Stock of the Company, provided only that the excess of the aggregate fair market value of the Shares subject to option immediately after such substitution over the purchase price thereof is not more than the excess of the aggregate fair market value of the Shares subject to option immediately before such substitution over the purchase price thereof, or (ii) upon written notice to the Optionee provide that the Option (including, in the discretion of the Board of Directors, any portion of such Option which is not then exercisable) must be exercised within sixty (60) days of the date of such notice or it will be terminated. If any adjustment under this Section 8(i) would create a fractional share of Stock or a right to acquire a fractional share, such shall be disregarded and the number of shares of Stock available under the Plan and the number of Shares covered under any Options previously granted pursuant to the Plan shall be the next lower number of shares of Stock, rounding all fractions downward. An adjustment made under this Section 8(i) by the Board of Directors shall be conclusive and binding on all affected persons. Except as otherwise expressly provided in this Plan, the Optionee shall have no rights by reason of any subdivision or consolidation of shares of stock of any class, or the payment of any stock dividend or any other increase or decrease in the number of shares of stock of any class, or by reason of any dissolution, liquidation, merger, or consolidation or spin-off of assets or stock of another corporation; and 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 prices of shares of Common Stock subject to an Option. The grant of an Option pursuant to the Plan shall not affect in any way the right or power of the Company to make adjustments, reclassifications, reorganizations or changes of its capital or business structure or to merge or to consolidate or to dissolve, liquidate or sell, or transfer all or any part of its business or assets. (j) Annual Limitation. 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 Optionee during any calendar year (under all incentive stock option plans of the Company) shall not exceed $100,000. Any excess over such amount shall be deemed to be related to and part of a non-qualified stock option granted pursuant to Section 9. 7 (k) General Restriction. Each Option shall be subject to the requirement -------------------- that if at any time the Board of Directors shall determine, in its discretion, that the listing, registration or qualification of the Shares subject to such Option upon any securities exchange or under any state or federal law, or the consent or approval of any government regulatory body, is necessary or desirable as a condition of, or in connection with, the granting of such Option or the issue or purchase of Shares thereunder, such Option may not be exercised in whole or in part unless such listing, registration, qualification, consent or approval shall have been effected or obtained free of any conditions not acceptable to the Board of Directors. Alternatively, such Options shall be issued and exercisable only upon such terms and conditions and with such restrictions as shall be necessary or appropriate to effect exemption from such listing, registration, or other qualification requirement. 9. NON-QUALIFIED OPTIONS The Board of Directors or the Committee may grant to Eligible Employees or Eligible Participants Options under the Plan which are not qualified incentive stock options under the provisions of Section 422 of the Code. Such non-qualified options shall be evidenced by Agreements in such form and not inconsistent with this Plan as the Committee shall approve from time to time, which Agreements shall contain in substance the same terms and conditions as set forth in Section 8 hereof with respect to qualified incentive options; provided, however, that the limitations set forth in Sections 8(a) and 8(c) with respect to Ten Percent Owners shall not be applicable to non-qualified options granted to any Ten Percent Owner, and the limitation set forth in Section 8(j) with respect to the annual limitation of incentive stock options shall not be applicable to non-qualified option grants; provided further, that non-qualified options may be granted at a purchase price equal to not less than 75% of the Market Price on the day the Option is granted. 10. OPTIONS TO NON-EMPLOYEE DIRECTORS Notwithstanding any provisions of the Plan to the contrary, the participation and eligibility of a Non-Employee Director in the Plan shall be limited exclusively to the following: (a) On March 2, 1997 and on March 2 of each year thereafter during the term of this Plan, each then Non-Employee Director of the Company shall be granted, without the necessity of action by the Board of Directors or any committee thereof, an Option to purchase 1,000 shares of Common Stock at an option exercise or purchase price equal to the Market Price of such Stock on the date of grant; provided, that in the event that the date of grant falls on a weekend or holiday, then the option exercise price shall be determined by reference to the Market Price of the Common Stock on the business day next preceding the grant date. (b) Options granted under this Section 10 shall be exercisable commencing on the date of grant or, with respect to any Option granted prior to stockholder approval of this Plan, upon the date of such stockholder approval, and thereafter until the earlier to occur of the following: the close of business on (i) the date which is the fifth anniversary of the date of grant; (ii) the date which is the 90th day following the date upon which such Non-Employee Director ceases to be a director of the Company for any reason other than death or permanent and total disability; or (iii) the date which is the first anniversary of the date on which such Non-Employee Director ceases to be a director of the Company as a result of death or permanent and total disability. (c) In all other respects, Options granted to Non-Employee Directors hereunder shall contain in substance the same terms and conditions as set forth in Section 9 hereof with respect to non-qualified options. No Non-Employee Director shall be eligible to receive Options hereunder except as provided in this Section 10. This Section may not be amended more than once every six months. 8 11. AMENDMENT OF THE PLAN The Plan may at any time or from time to time be terminated, modified or amended by the affirmative vote of not less than a majority of the shares present and voting thereon by the Company's shareholders at a meeting of the shareholders at which a quorum is present. The Board of Directors may at any time and from time to time modify or amend the Plan in any respect, except that without shareholder approval the Board of Directors may not (1) increase the maximum number of Shares for which Options may be granted under the Plan (other than increases due to changes in capitalization as referred to in Section 8(h) hereof), or (2) reduce the option exercise price or waiting period (except as otherwise expressly provided in Sections 8(h) and 8(i) hereof), or (3) extend the maximum period during which Options may be granted or exercised, or (4) change the class of persons eligible for Options under Section 6 hereof, or (5) otherwise materially modify (within the meaning of Rule 16b-3 of the Exchange Act) the requirements as to eligibility for participation in the Plan, or (6) otherwise materially increase (within the meaning of Rule 16b-3 of the Securities Exchange Act of 1934, as amended) the benefits accruing to participants under the Plan. The termination or any modification or amendment of the Plan shall not, without the written consent of an Optionee, affect his or her rights under an Option or right previously granted to him or her. With the written consent of the Optionee affected, the Board of Directors or the Committee may amend outstanding option agreements in a manner not inconsistent with the Plan. Without employee consent, the Board of Directors may at any time and from time to time modify or amend outstanding option agreements in such respects as it shall deem necessary in order that incentive options granted hereunder shall comply with the appropriate provisions of the Code and regulations thereunder which are in effect from time to time respecting "Qualified Incentive Options." The Company's Board of Directors may also suspend the granting of Options pursuant to the Plan at any time and may terminate the Plan at any time; provided, however, no such suspension or termination shall modify or amend any Option granted before such suspension or termination unless (1) the affected participant consents in writing to such modification or amendment or (2) there is a dissolution or liquidation of the Company. 12. BINDING EFFECT All decisions of the Board of Directors or the Committee involving the implementation, administration or operation of the Plan or any offering under the Plan shall be binding on the Company and on all persons eligible or who become eligible to participate in the Plan. 13.
