Two members of the Committee shall constitute a quorum for the transaction of business. The Committee shall be responsible to the Board for the operation of the Plan, and shall make recommendations to the Board with respect to participation in the Plan by employees of the Company and its Subsidiaries of and with respect to the extent of that participation. No member of the Board or the Committee shall be liable for any action or determination made by him in good faith. E. ELIGIBILITY The Board upon recommendation of the Committee, may grant Options to any key management employee (including an employee who is a director or an officer) of the Company or its Subsidiaries. Options may be awarded by the Board at any time and from time to time to new Participants, or to then Participants, or to a greater or lesser number of Participants, and may include or exclude previous Participants, as the Board, upon recommendation by the Committee shall determine, Options granted at different times need not contain similar provisions. F. OPTION PRICE The purchase price for Stock under each Option shall be determined by the Committee at the time the option is granted but in no event shall the purchase price be less than the par value of the Stock. G. TERMS AND CONDITIONS OF OPTIONS Options granted pursuant to the Plan shall be authorized by the Board and shall be evidenced by agreements in such form as the Board upon recommendation of the Committee, shall from time to time approve. Such agreements shall comply with and be subject to the following terms and conditions: 1. Employment Agreement. The Board may, in its discretion, include in any Option granted under the Plan a condition that the Participant shall agree to remain in the employ of, and to render services to, the Company or any of its Subsidiaries for a period of time (specified in the agreement) following the date the Option is granted. No such agreement shall impose upon the Company or any of its Subsidiaries, however, any obligation to employ the Participant for any period of time. 2. Time and Method of Payment. The Option Price shall be paid in full in cash at the time an Option is exercised under the 2 3 Plan. Otherwise, an exercise of any Option granted under the Plan shall be invalid and of no effect. Promptly after the exercise of an Option and the payment of the full Option Price, the Participant shall be entitled to the issuance of a stock certificate evidencing his ownership of such Stock. A Participant shall have none of the rights of a shareholder until shares are issued to him, and no adjustment will be made for dividends or other rights for which the record date is prior to the date such stock certificate is issued. 3. Number of Shares. Each Option shall state the total number of shares of Stock to which it pertains. 4. Option Period and Limitations on Exercise of Options. The Board may, in its discretion, provide that an Option may not be exercised in whole or in part for any period or periods of time specified in the Option agreement. Except as provided in the Option agreement, an Option may be exercised in whole in part at any time during its term. No Option may be exercised after the expiration of ten years from the date it is granted. No Option may be exercised for a fractional share of Stock. H. RIGHTS IN EVENT OF DEATH If a Participant dies while employed by the Company or any of its Subsidiaries, or within three months after having retired with the consent of the Company or any of its Subsidiaries, and without having fully exercised his Options the executors or administrators, or legatees or heirs of his estate shall have the right to exercise such Options to the extent that such deceased Participant was entitled to exercise the Options on the date of his death; provided, however, that in no event shall the Options be exercisable more than ten years from the date they were granted. I. NO OBLIGATIONS TO EXERCISE OPTION The granting of an Option shall impose no obligation upon the Participant to exercise such Option. J. NONASSIGNABILITY Options shall not be transferable other than by will or by the laws of descent and distribution, and during a Participant's lifetime shall be exercisable only by such Participant. 3 4 K. EFFECT OF CHANGE IN STOCK SUBJECT TO THE PLAN The aggregate number of shares of Stock available for options under the Plan shall be proportionately adjusted for any increase or decrease in the number of issued shares of Stock subsequent to the effective date of the Plan resulting from (1) a subdivision or consolidation of shares or any other capital adjustment, (2) the payment of a stock dividend or (3) other increase or decrease in such shares effected without receipt of consideration by the Company. If the Company shall be the surviving corporation in any merger or consolidation, any option shall pertain, apply, and relate to the securities to which a holder of the number of shares of Stock subject to the option would have been entitled after the merger or consolidation. Upon dissolution or liquidation of the Company, or upon a merger or consolidation in which the Company is not the surviving corporation, all Options outstanding under the Plan shall terminate; provided, however, that each Participant (and each other person entitled under Section H to exercise an Option) shall have the right, immediately prior to such dissolution, liquidation, merger or consolidation to exercise such Participant's Options, such Options being automatically exercisable by virtue of said dissolution, liquidation, merger or consolidation. L. AMENDMENT AND TERMINATION The Board, by resolution, may terminate, amend or revise the Plan with respect to any shares as to which Options have not been granted. Neither the Board nor the Committee may, without the consent of the holder of an Option, alter or impair any Option previously granted under the Plan. Unless sooner terminated, the Plan shall remain in effect for a period of ten years from the date of the Plan's adoption by the Board. Termination of the Plan shall not affect any Option previously granted. M. AGREEMENT AND REPRESENTATION OF EMPLOYEES As a condition to the exercise of any portion of an Option, the Company may require the person exercising such Option to represent and warrant at the time of such exercise that any shares of Stock acquired at exercise are being acquired only for investment and without any present intention to sell or distribute such shares if, in the opinion of counsel for the Company, such a representation is required under the Securities Act of 1933 or any other applicable law, regulation, or rule of any governmental agency. 4 5 N. RESERVATION OF SHARES OF STOCK The Company, during the term of this Plan, will at all times reserve and keep available, and will seek or obtain from any regulatory body having jurisdiction any requisite authority necessary to issue and to sell, the number of shares of Stock that shall be sufficient to satisfy the requirements of this Plan. The inability of the Company to obtain from any regulatory body having jurisdiction the authority deemed necessary by counsel for the Company for the lawful issuance and sale of its Stock hereunder shall relieve the Company of any liability in respect of the failure to issue or sell Stock as to which the requisite authority has not been obtained. 0. EFFECTIVE DATE OF PLAN The Plan shall be effective from the date that the Plan is approved by the Board. 5
