    Right to Exercise.
 (a)
    
    Subject to Sections 5(b) and (c), Section 7 and Section 10 below, the Option
will vest and become exercisable as provided in the attached Exhibit A, for so long as
Optionee remains continuously employed with the Company and its Subsidiaries. To the
extent the Option is exercisable, it may be exercised in whole or in part. In no event
shall Optionee be entitled to acquire a fraction of one Option Share pursuant to this
Option. Optionee shall be entitled to the privileges of ownership with respect to
Option Shares purchased and delivered to Optionee upon the exercise of all or part of
this Option.
 (b)
    
    Notwithstanding Section 5(a) above, the Option shall become immediately
exercisable in full, if at any time prior to the termination of the Option, a Change in
Control shall occur.
 (c)
    
    Notwithstanding Section 5(a) above, if the Optionee should die or become
permanently disabled while in the employ of the Company or any Subsidiary, this Option
shall immediately become exercisable in full and shall remain exercisable until
terminated in accordance with Section 7 below. The Optionee shall be considered to
have become permanently disabled if the Optionees employment terminates on account of
the Optionee having become permanently and totally disabled, as defined in Section
22(e)(3) of the Code.
 6.
    
    Notice of Exercise; Payment.To the extent then exercisable, the Option may be exercised in
whole or in part by written notice to the Company stating the number of Option Shares for
which the Option is being exercised and the intended manner of payment. The date of such
notice shall be the exercise date. The Option Price shall be payable (a) in cash or by check
acceptable to the Company, (b) by actual or constructive transfer to the Company of
nonforfeitable, unrestricted Common Shares that have been owned by the Optionee for more than
six (6) months prior to the date of exercise, (c) for exercises of Options that occur more
than one (1) year following the Date of Grant, by transfer to the Company of shares or vested
Options (including Options under this Agreement) for the purchase of shares of Common Stock
having a fair market value (net of the exercise price) at the time of exercise equal to the
portion of the Option Price for which such transfer is made, or (d) by a combination of such
methods of payment. The requirement of payment in cash shall be deemed satisfied if the
Optionee shall have made arrangements satisfactory to the Company with a bank or a broker who
is a member of the National Association of Securities Dealers, Inc. to sell on the exercise
date a sufficient number of the shares being purchased so that the net proceeds of the sale
transaction will at least equal the Option Price plus payment of any applicable withholding
taxes and pursuant to which the bank or broker undertakes to deliver the full Option Price
plus payment of any applicable withholding taxes to the Company on a date satisfactory to the
Company, but not later than the date on which the sale transaction will settle in the ordinary
course of business. As soon as practicable upon the Companys receipt of Optionees notice of exercise and payment, the Company shall direct the due
issuance of the Option Shares so purchased.
