Notwithstanding the preceding, the number of Shares available for issuance under the Plan always shall be a whole number.

5. Election to Purchase Shares.

5.1 Elections.

(i) Each Eligible Individual’s decision to participate in the Plan shall be entirely voluntary. An Eligible Individual may become a Participant in the Plan by enrolling or re-enrolling in the Plan during a Trading Window, provided that the Participant does not otherwise possess material non-public information concerning the Company (within the meaning of the 1934 Act) at the time of his or her election. In order to enroll, an Eligible Individual must complete, sign and submit to the Company an election form, in such form as the Committee will determine in its sole discretion.

(ii) On his or her election form, each Eligible Individual must authorize payroll deductions or, in the case of Directors, deductions from Fees for the purposes of purchasing fully vested Shares. Any deductions for this Plan will occur after normal and appropriate withholding for all Federal and State taxes and after voluntary withholdings for participation in other Company benefit plans. With respect to Officers, the payroll deductions may not reduce the individual’s compensation below an amount equal to two (2) times the federal or applicable state minimum wage, whichever is higher, required to be paid each pay period. Payroll deductions for a Participant who is an Officer will commence with the first full payroll period immediately following the date the Participant submits a properly completed election form to the Company. Deductions from Fees for a Participant who is a Director will commence on the first day on which the foregone Fees would have been paid to the Director and will apply only to Fees earned and paid after the date the Participant submits a properly completed election form to the Company.

5.2 Duration of Elections. An Eligible Individual’s election form will remain in effect unless amended or terminated as provided in Section 5.3.

5.3 Amendment or Termination of Elections.

(i) A Participant may terminate his or her participation in the Plan at any time by providing notice of termination to the Company in a manner and pursuant to such procedures as the Committee may determine from time to time. A Participant’s election to terminate participation shall be effective as soon as administratively practicable following the Company’s receipt of the Participant’s notice of termination, provided that the Participant has certified that his or her decision to terminate participation is made in good faith and in full compliance with both the letter and spirit of all federal and state securities laws.

(ii) A Participant may increase or decrease the rate of his or her payroll deductions or Fee deductions, as applicable, by submitting a new election form to the Company at any time during a Trading Window, provided that the Participant does not otherwise possess material non-public information concerning the Company (within the meaning of the 1934 Act) at the time of his or her new election. Notwithstanding the foregoing, a Participant may not decrease the rate of his or her deductions below 1% of his or her compensation or Fees, as applicable. Provided that a Participant has properly submitted a completed election form, the change in payroll or Fee deduction rate will be effective as soon as administratively practicable following the date the Company receives the Participant’s new election form and will apply only to compensation or Fees earned after such date.

6. Purchase and Delivery of Shares.

6.1 On, or as soon as administratively practicable following, each payroll date or, in the case of Directors, each date on which Fees would otherwise be paid, each Participant’s aggregate deductions for the applicable period will be converted into fully vested Shares based on the Fair Market Value of a Share on such date. No fractional Shares will be purchased. Any payroll or Fee deductions which are not sufficient to purchase a full Share will be paid to the Participant in cash.

6.2 Shares paid out to a Participant under the Plan will be delivered electronically to the Participant’s broker as indicated in the Participant’s election form or, if not specified, to the Participant’s broker(s) of record as listed in the Company’s records at the time of delivery.

7. Amendment or Termination of the Plan. The Committee may, at any time and for any reason, amend or terminate the Plan without regard to whether the amendment or termination may adversely affect any Participant. Without limiting the generality of the foregoing, such amendment or termination may be effective immediately notwithstanding that (i) elections have been made and are then in effect and (ii) deductions have been withheld but not yet applied to the purchase of Shares, in which case such deductions will be paid to the Participant in cash as soon as administratively practicable. No amendment or modification will require the consent of any Participants.

8. No Guarantee of Future Service. Neither the establishment or maintenance of the Plan, the purchase of Shares, nor any action of the Company or the Committee, will be held or construed to confer upon any Officer any right to be continued as an employee of the Company nor, upon dismissal, any right or interest in any specific assets of the Company other than as provided in the Plan. The Company expressly reserves the right to discharge any Officer at any time, with or without cause.

9. Tax Reporting. The participant will be responsible for reporting and paying any and all federal, state, or any other tax liabilities that arise from selling or otherwise disposing of the Shares. At any time, the Company may, but will not be obligated to, withhold from the Participant’s compensation the amount necessary for the Company to meet applicable withholding obligations, including any withholding required to make available to the Company any tax deductions or benefits attributable to the issuance, sale or disposition of Shares by the Participant.

10. Choice of Law. All questions concerning the construction, validity, and interpretation of the Plan will be governed by the law of the State of California, exclusive of the conflict of laws provisions thereof.

11. Severability. In the event any provision of the Plan shall be held illegal or invalid for any reason, the illegality or invalidity shall not affect the remaining parts of the Plan, and the Plan shall be construed and enforced as if the illegal or invalid provision had not been included.

12. Requirements of Law. The Company shall not be required to issue any certificate or certificates for Shares hereunder prior to fulfillment of all the following conditions: (a) the admission of such Shares to listing on all stock exchanges on which such class of stock is then listed; (b) the completion of any registration or other qualification of such Shares under any U.S. state or federal law or under the rulings or regulations of the Securities and Exchange Commission or any other governmental regulatory body, which the Committee shall, in its absolute discretion, deem necessary or advisable; and (c) the obtaining of any approval or other clearance from any U.S. state or federal governmental agency, which the Committee shall, in its absolute discretion, determine to be necessary or advisable.

13. Headings. The headings in the Plan are for convenience only and will not be deemed to constitute a part hereof nor to affect the meaning hereof.
