On the Date of Grant and on each of the first, second, and third anniversaries of the Date of Grant, the Option shall be Vested as to that number of Option Shares (rounded to the nearest whole share) equal to the total number of Option Shares multiplied by the Annual Vesting Rate indicated below. EMPLOYEE: DATE OF GRANT: NUMBER OF OPTION SHARES: EXERCISE PRICE PER OPTION SHARE: EXPIRATION DATE: ANNUAL VESTING RATE: 25% The Option is intended to be an Incentive Stock Option to the extent permitted by Section 422(d) of the Code. That part of the Option which cannot qualify as an Incentive Stock Option shall be a Non-Qualified Stock Option. 2. ACCELERATION AND TERMINATION OF OPTION. (a) TERMINATION BY DEATH. If an Employee incurs a Termination of Employment by reason of death, any Stock Option held by such Employee will become fully Vested on the date of Death and may thereafter be exercised, for a period of one year (or such other period as the Committee may specify) from the date of such death or until the expiration of the stated term of such Stock Option, whichever period is the shorter. (b) TERMINATION BY REASON OF DISABILITY. If an employee incurs a Termination of Employment by reason of Disability, any Stock Option held by such Employee may thereafter be exercised by the Employee, to the extent it was Vested at the time of termination, for a period of one year from the date of such Termination of Employment or until the expiration of the stated term of such Stock Option, whichever period is the shorter; provided, however, that if the Employee dies within such one-year period, any unexercised Stock Option held by such Employee shall, notwithstanding the expiration of such one-year period, continue to be exercisable for a period of 12 months from the date of such death or until the expiration of the stated term of such Stock Option, whichever period is the shorter. (c) TERMINATION BY REASON OF RETIREMENT. If an Employee incurs a Termination of Employment by reason of Retirement, any Stock Option held by such Employee will become fully Vested one year after the date of Retirement (First Year Retirement Anniversary Date) and may thereafter be exercised by the Employee, for a period of one year from the date of the First Year Retirement Anniversary Date or until the expiration of the stated term of such Stock Option, whichever period is the shorter. If the Employee dies prior to the First Year Retirement Anniversary Date, any Stock Option held by the Employee shall be fully Vested on the date of death and any unexercised Stock Option shall continue to be exercisable for a period of 12 months from the date of such death or until the expiration of the stated term of such Stock Option, whichever period is the shorter. (d) OTHER TERMINATION. Unless otherwise determined by the Committee, if an Employee incurs a Termination of Employment for any reason other than death, Disability or Retirement, any Stock Option held by such Employee shall thereupon terminate, except that if such Termination of Employment of the Employee is involuntary and without Cause, such Stock Option shall be fully Vested and may be exercised within the lesser of six months from the date of such Termination of Employment or the balance of such Stock Option's term. Notwithstanding the foregoing, if an Employee incurs a Termination of Employment at or after a Change in Control, other than by reason of death, Disability or Retirement, any Stock Option held by such Employee shall be Vested and may be exercised within the lesser of (1) six months and one day from the date of such Termination of Employment, and (2) the balance of such Stock Option's term. 3. ADJUSTMENTS. In the event of any merger, reorganization, consolidation, recapitalization, stock dividend, spin-off, stock split, extraordinary distribution with respect to the Common Stock or other similar change in corporate structure affecting the Common Stock, such substitution or adjustments shall be made in the aggregate number of shares reserved for issuance under the Plan, in the number and option price of shares subject to outstanding Stock Options and Stock Appreciation Rights, and the number of shares subject to other outstanding Awards granted under the Plan as may be determined to be appropriate by the Committee, in its sole discretion; provided, however, that the number of shares subject to any Award shall always be a whole number. 4. EXERCISE. The Option shall be exercisable during Employee's lifetime only by Employee or by his or her guardian or legal representative, and after Employee's death only by the person or entity entitled to do so under Employee's last will and testament or applicable intestate law.

Such notice shall also specify the number of Purchased Shares which are acquired pursuant to the exercise of an Incentive Stock Option and pursuant to the exercise of a Non-Qualified Stock Option.

If the Company is obligated to withhold an amount on account of any federal, state or local tax imposed as a result of the exercise of the Option, including, without limitation, any federal, state or other income tax, or any F.I.C.A., state disability insurance tax or other employment tax, then Employee shall, concurrently with such exercise, pay such amount to the Company in cash or by check payable to the Company or by reducing the number of shares of Common Stock to be issued and delivered to Employee upon such exercise (such reduction to be valued on the basis of the aggregate Fair Market Value (determined on the date of such exercise) of the additional shares of Common Stock that would otherwise have been issued and delivered upon such exercise), provided that the Company is not then prohibited from purchasing or acquiring such additional shares of Common Stock. 6. STOCK EXCHANGE REQUIREMENTS; APPLICABLE LAWS. All certificates for shares of Common Stock or other securities delivered under this Agreement shall be subject to such stock transfer orders and other restrictions as the Committee may deem advisable under the rules, regulations and other requirements of the Commission, any stock exchange upon which the Common Stock is then listed and any applicable Federal or state securities law, and the Committee may cause a legend or legends to be put on any such certificates to make appropriate reference to such restrictions. 7.
