The Option may be exercised in whole or in part. The exercise generally must be accompanied by, or make provision for, full payment in cash; by check; or by surrendering unrestricted shares of Common Stock having a value on the date of exercise equal to the exercise price, together with proof that such shares, if acquired through a previous option exercise, have been owned by the optionee for at least six months prior to the date of exercise of the Option; or in any combination of the foregoing; however, if you wish to pay with shares of Common Stock already held by you, you may submit an Affidavit of Ownership form attesting to the ownership of the shares instead of sending in actual share certificates.

Nontransferability. The Option is not transferable except by will or by the laws of descent and distribution, and may not be sold, assigned, pledged or encumbered in any way, whether by operation of law or otherwise. The Option may be granted only to, and exercised only by you during your lifetime, except in the case of a permanent disability involving mental incapacity.

Limitation of Rights. You will not have any rights as a stockholder with respect to the shares covered by the Option until you become the holder of record of such shares by exercising the Option. Neither the Plan, the granting of the Option nor this Award Notice gives you any right to remain employed by the Company and its Subsidiaries.

Upon termination of your employment with the Company and its Subsidiaries ("termination") by reason of death, disability, termination without Cause or for Good Reason as defined in your Employment Agreement dated May 4, 2006, or retirement, the Option will remain exercisable for the lesser of: 1) five (5) years following your date of termination, or, 2) the Expiration Date. Upon termination due to voluntary resignation, the Option will remain exercisable for the lesser of: 1) ninety (90) days following your date of termination, or, 2) the Expiration Date. Upon termination for Cause, any portion of the Option not previously exercised by you will be canceled and forfeited by you, without payment of any consideration by the Company. Upon termination for a reason other than those described in this Section, the Committee will determine if all or any portion of the Option will remain exercisable and if so, the period of time the Option may be exercised, up to, but not to exceed the Expiration Date.

Noncompetition; Confidentiality. You will forfeit all rights under the Option if you violate the noncompetition and confidentiality provisions contained in Section 20 of the Plan.

Restrictions on Issuance of Shares. If at any time the Company determines that listing, registration or qualification of the shares covered by the Option upon any securities exchange or under any state or federal law, or the approval of any governmental agency, is necessary or advisable as a condition to the exercise of the Option, the Option may not be exercised in whole or in part unless and until such listing, registration, qualification or approval shall have been effected or obtained free of any conditions not acceptable to the Company.

Change in Ownership; Change in Control. Sections 25 and 26 of the Plan contain certain special provisions that will apply to the Option in the event of a Change in Ownership or Change in Control, respectively.

Adjustment of Shares. If the number of outstanding shares of Common Stock changes through the declaration of stock dividends or stock splits, the number of shares subject to the Option and the exercise price of the Option automatically will be adjusted. If there is a change in the number of outstanding shares of Common Stock or any change in the outstanding stock in the Company, the Committee will make any adjustments and modifications to the Option that it deems appropriate. In the event of any other change in the capital structure or in the Common Stock of the Company, the Committee is authorized to make appropriate adjustments to the Option.

Plan Controls. In the event of any conflict between the provisions of the Plan and the provisions of this Award Notice, the provisions of the Plan will be controlling and determinative.
