The maximum number of Shares with respect to which options may be granted during any Plan Year to any Participant shall be 300,000 Shares. 3 9. Withholding ----------- The Company shall have the right to deduct and withhold from any cash otherwise payable to a Participant, or require that a Participant make arrangements satisfactory to the Company for payment of, such amounts as the Company shall determine for the purpose of satisfying its liability to withhold federal, state or local income or FICA taxes incurred by reason of the grant or exercise of an option. In the discretion of the Committee, a Participant may be permitted to satisfy the Company's withholding requirements by tendering previously acquired Shares or by electing to have the Company withhold Shares otherwise issuable to the Participant, having a fair market value, on the date income is recognized pursuant to the exercise of a Non-Qualified Stock Option, in the amount required to be withheld. The election shall be made in writing and shall be made according to such rules and in such form as the Committee shall determine. 10. Exercise of Options ------------------- Each option granted under the Option Plan will be exercisable on such date or dates and during such period and for such number of Shares as shall be determined pursuant to the provisions of the option agreement evidencing such option. Subject to the provisions of the Plan, the Committee shall have complete authority, in its discretion, to determine the extent, if any, and the conditions under which an option may be exercised in the event of the death of the Participant or in the event the Participant leaves the employ of the Company or has his employment terminated by the Company. The purchase price of any option may be paid (a) in cash or its equivalent; (b) with the consent of the Committee, by tendering (including by attestation) previously acquired Shares valued at their fair market value as determined by the Committee; or (c) with the consent of the Committee, by electing to have the Company withhold Shares otherwise issuable to the Participant, having a fair market value on the date of exercise of a Non-Qualified stock option, in the amount required to be paid; or with the consent of the Committee, by any combination of (a), (b), and (c).

The Committee may provide one or more means to enable Participants and the Company to defer delivery of Shares otherwise deliverable upon exercise of an option, on such terms and conditions as the Committee may determine, including by way of example the manner and timing of making a deferral election, the treatment of dividends paid on the Shares during the deferral period and the permitted distribution dates or events. No such deferral means may result in an increase in the number of shares of Common Stock issuable hereunder. 11. Transferability --------------- Options under the Plan are not transferable otherwise than by will or the laws of descent or distribution, except that a Participant may, to the extent allowed by the Committee and in the manner specified by the Committee, transfer any option grant 4 award. The Committee shall have authority, in its discretion, to amend existing stock option agreements and to allow the transfer of any existing option grant award in the manner specified by the Committee. 12. Agreements ---------- Options granted pursuant to the Plan shall be evidenced by stock option agreements in such form as the Committee shall from time to time adopt. 13. Adjustment of Number of Shares ------------------------------ In the event a dividend shall be declared upon the Common Stock of the Company payable in Shares (other than a stock dividend declared in lieu of an ordinary cash dividend), the number of Shares then subject to any such option, the maximum number of shares set forth in the second sentence of Section 8, and the number of Shares reserved for issuance pursuant to the Plan but not yet covered by an option, shall be adjusted by adding to each Share the number of Shares which would be distributable thereon if such Share had been outstanding on the date fixed for determining the stockholders entitled to receive such stock dividend. In the event the outstanding Shares of the Common Stock of the Company shall be changed into or exchanged for a different number or kind of Shares of stock or other securities of the Company or of another corporation, whether through reorganization, recapitalization, stock split-up, combination of Shares, merger or consolidation, then there shall be substituted for each Share reserved for issuance pursuant to the Plan, but not yet covered by an option, the maximum number of shares set forth in the second sentence of Section 8, the number of shares then subject to any such option, the number and kind of Shares of stock or other securities into which each outstanding Share shall be so changed or for which each such Share shall be exchanged. In the event there shall be any change, other than as specified above in this paragraph in the number or kind of outstanding Shares or of any stock or other security into which such Common Stock shall have been changed or for which it shall have been exchanged, then if the Committee shall in its sole discretion determine that such change equitably requires an adjustment in the number or kind of Shares theretofore reserved for issuance pursuant to the Plan, but not yet covered by an option, the maximum number of shares set forth in the second sentence of Section 8 and/or of the Shares then subject to an option or options, such adjustment shall be made by the Committee and shall be effective and binding for all purposes of the Plan and of each stock option agreement. The option price in each stock option agreement for each Share or other securities substituted or adjusted as provided for in this paragraph shall be determined by dividing the option price in such agreement for each Share prior to such substitution or adjustment by the number of Shares or the fraction of a share substituted for such Share or to which such Share shall have been adjusted. No adjustment or substitution provided for in this paragraph shall require the Company in any stock option agreement to sell a fractional Share, and the total substitution or adjustment with respect to each stock option agreement shall be limited accordingly. 5 14. Shares Available ---------------- There shall be reserved, for the purpose of the Plan, a total of 1,500,000 Shares of Common Stock (or the number and kind of Shares of stock or other securities which, in accordance with Section 13 hereof, shall be substituted for said Shares or to which said Shares shall be adjusted). Such Shares may be, in whole or in part, authorized and unissued Shares or issued Shares which shall have been reacquired by the Company. In the event that (i) an option granted under the option plan to any employee expires or is terminated unexercised as to any Shares covered thereby, (ii) Shares are forfeited for any reason under the Plan, or (iii) Shares are tendered to exercise an option, such Shares shall thereafter be available for the granting of options under the Plan. 15. Expenses -------- The expenses of administering the Plan shall be borne by the Company. 16. Non-Exclusivity --------------- Neither the adoption of the Plan by the Board of Directors nor the submission of the Plan to the stockholders of the Company for approval shall be construed as creating any limitations on the power of the Board of Directors to adopt such other incentive arrangements as it may deem desirable, and such arrangements may be either generally applicable or applicable only in specific cases. 17. Amendment --------- The Board of Directors, without further approval of the stockholders, may from time to time amend the Plan in such respects as the Board may deem advisable; provided, however, that no amendment shall become effective without prior approval of the stockholders which would (a) increase the maximum number of Shares which may be awarded, or for which options may be granted, in the aggregate under the Plan; or (b) reduce the minimum option price which may be established under the Plan. No amendment shall, without the Participant's consent, alter or impair any of the rights or obligations under any option theretofore granted to him under the Plan.
