This Plan and all Options granted under this Plan are subject to all of the terms and conditions of the 1998 Stock Incentive Plan. Options granted under this Plan are not intended to qualify as incentive stock options under Section 422 of the Internal Revenue Code of 1986, as amended. 2. Acceleration and Termination of Options. --------------------------------------- (A) Change of Control. A Participant's Options shall become fully vested ----------------- and exercisable upon the date of a Change of Control (as hereinafter defined), if the date on which the Participant's employment with the Company and all of its subsidiaries terminates (such event shall be referred to as the "Termination of Employment") does not occur before the Change in Control.

(B) Termination of Employment. ------------------------- (I) Retirement. If a Participant's Employment is Terminated by reason of ---------- the Participant's retirement in accordance with the Company's then-current retirement policy ("Retirement"), then (A) the portion of the Participant's Options that have not vested on or prior to the date of such Retirement shall terminate on such date and (B) the remaining vested portion of the Options shall terminate upon the earlier of the date three (3) months after the date of such Termination of Employment and the Expiration Date. (II) Death or Permanent Disability. If a Participant's Employment is ----------------------------- Terminated by reason of the death or Permanent Disability (as hereinafter defined) of the Participant, then (A) the portion of the Option that has not vested on or prior to the date of such Termination of Employment shall terminate on such date and (B) the remaining vested portion of the Option shall terminate upon the earlier of the Expiration Date or the first anniversary of the date of such Termination of Employment. "Permanent Disability" shall mean the inability to engage in any substantial gainful activity by reason of any medically determinable physical or mental impairment that can be expected to result in death or that has lasted or can be expected to last for a continuous period of not less than 12 months. A Participant shall not be deemed to have a Permanent Disability until proof of the existence thereof shall have been furnished to the Board in such form and manner, and at such times, as the Board may require. Any determination by the Board that a Participant does or does not have a Permanent Disability shall be final and binding upon the Company and the Participant. (III) Other Termination. If a Participant's Employment is Terminated for ----------------- any reason other as set forth in clauses (i) and (ii) above, including termination by voluntary resignation, then (A) the portion of the Participant's Options that have not vested on or prior to the date of Termination of Employment shall terminate on such date and (B) the remaining vested portion of the Options shall terminate upon the earlier of the date three (3) months after the date of such Termination of Employment and the Expiration Date. 7 (C) Death Following Termination of Employment. Notwithstanding anything to the ----------------------------------------- contrary contained in this Plan, if a Participant shall die at any time after the Termination of his or her Employment and prior to the Expiration Date, then the remaining vested portion of that Participant's Options shall terminate on the earlier of the Expiration Date or the first anniversary of the date of such death.

(E) Other Events Causing Termination of Option. Notwithstanding anything to ------------------------------------------ the contrary contained in this Plan, a Participant's Options shall terminate upon the consummation of any of the following events, or, if later, the thirtieth day following the first date upon which such event shall have been approved by both the Board and the shareholders of the Company: (I) the dissolution or liquidation of the Company; or (II) a sale of substantially all of the property and assets of the Company, unless the terms of such sale shall provide otherwise. 3.

Exercise. -------- (A) Options of a Participant shall be exercisable during the Participant's lifetime only by the Participant or by his or her guardian or legal representative, and after the Participant's death only by the person or entity entitled to do so under the Participant's last will and testament or applicable intestate law.

Automated Quotations System ("NASDAQ") or such other system then in use, or, if the Common Shares were not quoted by any such organization on such immediately preceding business day, the average of the closing bid and asked prices on such day as furnished by a professional market maker making a market in the Common Shares selected by the Board. If Common Shares are not registered on the Determination Date under applicable rules of the Securities and Exchange Commission, the Fair Market Value shall be determined by the Board of Directors upon consultation with an investment banker familiar with the Company and the market for its shares. 5. Payment of Withholding Taxes. If the Company becomes obligated to withhold ---------------------------- an amount on account of any tax imposed as a result of the exercise of Options by a Participant, including, without limitation, any federal, state, local or other income tax, or any F.I.C.A., state disability insurance tax or other employment tax, then the Participant shall, on the first day upon which the Company becomes obligated to pay such amount to the appropriate taxing authority, pay such amount to the Company in cash or by check payable to the Company, or by shares of Company stock owned by the Participant or otherwise distributable pursuant to the exercise of the Option (except that, if shares are used to satisfy such withholding obligation, the Company may impose such reasonable restrictions relating to the delivery of the shares as may be necessary to avoid the Company incurring a charge to earnings as a result of such use of shares). 6. Notices.

Stock Exchange Requirements; Applicable Laws. Notwithstanding anything to -------------------------------------------- the contrary in this Plan, no shares of stock purchased upon exercise of Options, and no certificate representing all or any part of such shares, shall be issued or delivered if (i) such shares have not been admitted to listing upon official notice of issuance on each stock exchange upon which shares of that class are then listed or (ii) in the opinion of counsel to the Company, such issuance or delivery would cause the Company to be in violation of or to incur liability under any federal, state or other securities law, or any requirement of any stock exchange listing agreement to which the Company is a party, or any other requirement of law or of any administrative or regulatory body having jurisdiction over the Company. 8. Nontransferability.
