ARTICLE IV TERMS OF OPTION 4.1 OPTION AGREEMENT--Each Option shall be evidenced by a written Stock Option Agreement, which shall be executed by the Optionee and an authorized officer of the Company. The terms and conditions of a Stock Option Agreement shall be consistent with the Plan, but the Committee shall have the power and authority to include such other terms and conditions which are not inconsistent with the Plan. The Committee may, in its discretion, incorporate different terms and conditions in the Stock Option Agreement offered to each Optionee consistent with this Section 4.1. 4.2 OPTION EXERCISE PRICE--The exercise price of the shares subject to each Option shall be determined by the Committee and set forth in the respective Stock Option Agreement. 4.3 PERIOD AND EXERCISE OF OPTION-- (a) PERIOD--Subject to the provisions of the Stock Option Agreement and the other restrictions contained in the Plan, an Option shall become exercisable at such times and in such installments (which may be cumulative) as the Committee shall provide in the terms of each individual Option, and the period during which such Option (or installment) may be exercised shall terminate at such times as the Committee shall provide in the terms of each individual Option. The Committee may adopt a resolution after an Option is granted and on such terms and conditions as it deems appropriate whereby the time during which such Option or any portion thereof may be exercised is accelerated. No Option may be exercised to any extent by anyone after the first to occur of the following events: (i) the expiration of ten (10) years from the date the Option is granted; (ii) the time of the Optionee's Termination of Employment unless such Termination of Employment results from his death, Permanent Disability or Retirement; (iii) the expiration of thirty (30) days from the time of the Optionee's Termination of Employment by reason of his Permanent Disability or Retirement; (iv) the expiration of ninety (90) days from the time of the Optionee's Termination of Employment by reason of his death; or (v) the Optionee shall engage in willful misconduct which injures the Company or any of its Subsidiaries as determined by the Committee. Except as set forth in subsections (ii), (iii) and (iv) above, an Option shall not be exercisable during the Option Period unless the Optionee shall have been continuously employed by the Company or a Subsidiary from the date the Option was granted until its date of exercise. Upon expiration of the Option Period, as accelerated if applicable, the Option shall terminate with respect to all shares of Stock not already actually purchased and paid for in full by the Optionee. (b) PERSONS ELIGIBLE TO EXERCISE--An Option granted hereunder (or portion thereof) shall be exercisable only by the Optionee; provided, however, that in the event of an Optionee's death, the heirs, executors or personal representatives of such Optionee may exercise the Option. (c) PARTIAL EXERCISE--Any exercisable portion of the Option or the entire Option, if then wholly exercisable, may be exercised in whole or in part during the applicable Option Period; provided, however, that the Company shall not be required to issue fractional shares and the Committee may, by the terms of the Option, require any partial exercise to be with respect to a specified minimum number of shares. (d) MANNER OF EXERCISE--An exercisable Option, or any exercisable portion thereof, may be exercised solely by delivery to the Secretary of the Company or his office of all of the following prior to the time when such Option or portion thereof becomes unexercisable under the terms of this Plan or the applicable Stock Option Agreement: (i) Notice in writing signed by the Optionee or other person then entitled to exercise such Option or portion thereof, stating that such Option or portion thereof is exercised, such notice complying with all applicable rules established by the Committee; (ii) Full payment (in cash or by check) of the exercise price for the shares with respect to which such Option or portion thereof is exercised; (iii) Such representations and documents as the Committee, in its absolute discretion, deems necessary or advisable to effect compliance with all applicable provisions of the Securities Act and any other federal or state securities laws or regulations. The Committee may, in its absolute discretion, also take whatever additional actions it deems appropriate to effect such compliance including, without limitation, placing legends on share certificates and issuing stop-transfer orders to transfer agents and registrars; (iv) Full payment (in cash or by check) to the Company of all amounts which, under federal, state or local law, it is required to withhold in connection with the exercise of the Option; and (v) In the event the Option or portion thereof shall be exercised by any person or persons other than the Optionee, appropriate proof of the right of such person or persons to exercise the Option. 4.4 CONDITIONS TO ISSUANCE OF STOCK CERTIFICATES--The Company shall not be required to issue or deliver any certificate or certificates for shares of Stock purchased upon the exercise of any Option or portion thereof prior to fulfillment of all of the following conditions: (a) The completion of any registration or other qualification of or notice regarding such shares under any state or federal law or under the rules or regulations of the Securities and Exchange Commission or any other governmental regulatory body, which the Committee shall, in its absolute discretion, deem necessary or advisable; (b) The obtaining of any approval or other clearance from any state or federal governmental agency which the Committee shall, in its absolute discretion, determine to be necessary or advisable; and (c) The lapse of such reasonable period of time following the exercise of the Option as the Committee may establish from time to time for reasons of administrative convenience, provided that, upon issuance, the shares shall be considered issued and outstanding as of the date such Option was exercised. 4.5 RIGHTS AS STOCKHOLDERS--The holders of Options shall not be, nor have any of the rights or privileges of, stockholders of the Company in respect of any shares purchasable upon the exercise of any part of an Option unless and until certificates representing such shares have been issued by the Company to such holders. 4.6 MERGER, CONSOLIDATION, ACQUISITION, LIQUIDATION OR DISSOLUTION--In the event the Company shall not be the surviving corporation in any merger, consolidation, or reorganization, or in the event of acquisition by another corporation of all or substantially all of the assets of the Company, every Option outstanding hereunder may be assumed (with appropriate changes) by the surviving, continuing, successor or purchasing corporation, as the case may be, subject to any applicable provisions of the Code or replaced with new Options of comparable value (in accordance with Section 424(a) of the Code). In the event (i) that such surviving, continuing, successor or purchasing corporation, as the case may be, does not assume or replace the outstanding Options hereunder, or (ii) of liquidation or dissolution of the Company, the Committee may provide that each Optionee shall have the right, within a period commencing not more than thirty (30) days immediately prior to and ending on the day immediately prior to such merger, consolidation, reorganization or acquisition by another corporation of all or substantially all of the assets of the Company or the liquidation or dissolution of the Company, to exercise the Optionee's outstanding Options to the extent of all or any part of the aggregate number of shares subject to such Option(s).
