|                         | 
|Restrictions on Exercise |  | The Company will not permit you to exercise this option if the issuance of shares at that time would violate any law or regulation.                                                                                                                                                                                                                                                                                                                                                                        
|                         | 
|Notice of Exercise       |  | When you wish to exercise this option, you must notify the Company by filing the proper Notice of Exercise form at the address given on
the form. Your notice must specify how many shares you wish to purchase. Your notice must also specify how your shares should be registered. The notice will be effective when the Company receives it.

so.

|                                        |  |      Certificates for shares of Company stock that you own, along with any forms needed to effect a transfer
of those shares to the Company. The value of the shares, determined as of the effective date of the option exercise, will be applied to the option exercise price. Instead of surrendering shares of Company stock, you may attest to the ownership of
those shares on a form provided by the Company and have the same number of shares subtracted from the option shares issued to you.

|                                        |  |      Irrevocable directions to a securities broker approved by the Company to sell all or part of your
option shares and to deliver to the Company from the sale proceeds an amount sufficient to pay the option exercise price and any withholding taxes. (The balance of the sale proceeds, if any, will be delivered to you.) The directions must be given by
signing a special Notice of Exercise form provided by the Company.                                                                                                                                                                          
|                                        | 
|Withholding Taxes and Stock Withholding |  | You will not be allowed to exercise this option unless you make arrangements acceptable to the Company to pay any withholding taxes that may be due as a result of the option exercise. With the
Companys consent, these arrangements may include withholding shares of Company stock that otherwise would be issued to you when you exercise this option. The value of these shares, determined as of the effective date of the option exercise,
will be applied to the withholding taxes.                                                                                                                    
|                                        | 
|Restrictions on Resale                  |  | You agree not to sell any option shares at a time when applicable laws, Company policies or an agreement between the Company and its underwriters prohibit a sale. This restriction will apply as
long as your Service continues and for such period of time after the termination of your Service as the Company may specify.                                                                                                                                                                                                                                                                                  
|                                        | 
|Transfer of Option                      |  | Prior to your death, only you may exercise this option. You cannot transfer or assign this option. For instance, you may not sell this option or use
it as security for a loan. If you attempt to do any of these things, this option will immediately become invalid. You may, however, dispose of this option in your will or a beneficiary designation. Regardless of any marital property settlement agreement, the Company is not obligated to honor a notice of exercise from your former spouse, nor is the Company obligated
to recognize your former spouses interest in your option in any other way.
|                                        | 
|Retention Rights                        |  | Your option or this Agreement does not give you the right to be retained by the Company or a subsidiary of the Company in any capacity. This Agreement shall not in any way be construed or
interpreted so as to affect adversely or otherwise impair the right of the Company or the stockholders to remove you from the Board of Directors at any time in accordance with the provisions of applicable law.
