Page 6 - ESPP Plan Summary

Purchase of Company Stock. Enrollment in the plan for a particular calendar quarter
constitutes the grant by the Company to you of an option to purchase shares of the Company’s
common stock for each monthly offering period during that calendar quarter. Your option will be for
the number of whole and fractional shares that can be purchased as of the last business day of each
month within such calendar quarter with the amount credited to your plan account on that date at a
purchase price equal to 95% of the fair market value of the common stock on that date.

As soon as practicable after the end of each calendar month, the custodian for the plan will
purchase the number of shares of the Company’s common stock credited to your plan account as of
the last business day of the month. The Company shall pay any additional amounts required by the
custodian of the plan to purchase the required number of shares.

Dividends, if any, paid on the shares of common stock held in your plan account will
automatically be reinvested by the custodian in additional shares of Company common stock
purchased in the open market and credited to your plan account. The shares purchased pursuant to
the reinvestment of dividends will be purchased without discount from fair market value of the
common stock.

Your enrollment in the plan, changes you make to your elections and any subsequent sale of
shares are subject to the restrictions of applicable securities laws and the Company’s Insider Trading
Policy.

Your Program Stock Account. Except in the event of your termination of employment or
death, you may not request a distribution of, or sell, transfer or dispose of shares of common stock in
your plan account, other than shares acquired through the reinvestment of dividends, until a date
which is at least one year following the date that the shares were initially credited to your plan
account. After this date, you may request a distribution of all or a portion of the whole number of
shares credited to your plan account.

As soon as practicable after your enrollment in the plan terminates, you will be paid all cash
amounts credited to your plan account as of the date of termination. If your enrollment in the plan
terminates as a result of your termination of employment or the termination of the plan, you will
receive certificates representing whole shares of common stock credited to your plan account. You
will also receive cash equal to the current fair market value of any fractional shares credited to your
account.

Your Rights as a Stockholder. You will become a stockholder with respect to stock only
when the purchase of such stock is completed under the program. At that time, you will have the
same rights as other stockholders, including voting rights and the right to receive dividends.

Your Rights as an Employee. The program is not a contract of employment, and
participation in the program will not give you the right to be retained in the employ of the Company
or any Employer. Your enrollment in the program constitutes a waiver of any and all rights to
compensation or damages relating to the cessation of your eligibility to participate in the program
upon termination of the program or termination of the your employment for any reason whatsoever.

No Transfer or Assignment. Your rights under the program may not be sold, pledged,
assigned or transferred, voluntarily or involuntarily, and any such attempted sale, pledge, assignment
or transfer shall be without effect.
