4. Participation in the Plan.

  (a) The individuals who shall be eligible to receive grants of Purchase Rights under an Offering shall be all Eligible Employees of the Company or of any Participating Subsidiary who are so employed by the Company or Participating Subsidiary during the applicable Enrollment Period and on the Grant Date of such Offering. Notwithstanding the preceding sentence to the contrary, no Eligible Employee shall be eligible to effect a purchase under an Offering if immediately thereafter and after giving effect thereto, the aggregate value or voting power of all shares of stock of the Company and any Subsidiary then owned by such individual, either directly or indirectly, within the meaning of the applicable sections of the Code and including all shares of stock with respect to which such individual holds options, would equal or exceed in the aggregate 5% of the total value or combined voting power of all classes of stock of the Company or any Subsidiary.

Amounts credited to a Participant’s Plan account shall not be credited with interest or other notional earnings.

5. Shares of Common Stock Subject to the Plan.

  (a) The Common Stock subject to an Offering may be from (a) authorized but unissued shares of stock, (b) shares of stock held in treasury of the Company, or (c) shares of stock acquired by the Company, including shares purchased on the open market. Subject to adjustment in accordance with the provisions of Section 10(g) hereof, the total number of shares of Common Stock which may be the subject of Offerings under the Plan shall not exceed in the aggregate 100,000 shares of Common Stock.

  (b) In the event that any shares of Common Stock, which are the subject of an Offering, are not purchased, such unpurchased shares of Common Stock shall again be available for subsequent Offerings.

6. Number of Shares That an Participant May Purchase.

  (a) The number of shares of Common Stock that a Participant may purchase in an Offering shall be determined by dividing such Participant’s contributions credited to such Employee’s Plan account as of the applicable Expiration Date by the purchase price determined under Section 10(b); provided, however, that such purchase shall be subject to the limitations set forth in Sections 6(b) and 6(c).

  (b) The maximum number of shares of Common Stock that a Participant may purchase in an Offering is that number of shares of Common Stock that has a Fair Market Value on the Grant Date of the Offering equal to $25,000.

  (c) Notwithstanding the foregoing provisions of the Plan, no Participant may purchase under Offerings in any single calendar year a number of shares of Common Stock which, together with all other shares in the Company and Subsidiaries which the Participant may be entitled to purchase in such year pursuant to Offerings and under any other employee stock purchase plan, as defined in Section 423 of the Code, has an aggregate Fair Market Value (measured in each case as of the applicable Grant Date) in excess of $25,000. For the avoidance of doubt (i) if during the Offering that begins on January 1 a Participant purchases shares of Common Stock with a Fair Market Value (as of the January 1 Grant Date) that equals $25,000, then the Employee shall not be eligible to participate in the Offering that begins on the following July 1 and (ii) the number of shares of Common Stock a Participant may purchase in the Offering that begins on July 1 is equal to the number of shares of Common Stock with a Fair Market Value (as of the July 1 Grant Date) equal to $25,000 reduced by the Fair Market Value (as of the preceding January 1 Grant Date) of the shares of Common Stock purchased in the preceding Offering.

7. Method of Payment of Contributions.

  (a) A Participant shall elect to have payroll deductions made on each payday during the Offering with a minimum payroll deduction for each pay period of $10.00 and a maximum payroll deduction of ten percent (10%) of such Participant’s Compensation during the Offering. All payroll deductions made by a Participant shall be credited to his or her account under the Plan. If the election is reduced to zero percent (0%), the Participant is considered withdrawn from the Plan and money will be refunded pursuant to Section 9(a).

  (b) A Participant may discontinue his or her participation in the Plan as provided in Section 9.

  (c) Notwithstanding the foregoing, to the extent necessary to comply with Section 423(b)(8) of the Code and Section 7 hereof, the Company may cause a Participant’s payroll deductions to be decreased in respect of an Offering year to zero percent (0%).

8. Exercise of Purchase Rights. Unless a Participant withdraws from an Offering or terminates his or her Employee status as provided in Section 9 prior to the Expiration Date of an Offering, his or her right to purchase shares of Common Stock in the Offering will be exercised and shares will be deposited to the Participant’s individual Plan designated brokerage accounts as soon as administratively practicable after each Offering Period’s Expiration Date. The number of shares of Common Stock purchased using each Expiration Date as the effective purchase date shall equal that number of shares that is the quotient of the amount credited to the Participant’s account under the Plan on the Expiration Date and the purchase price determined under Section 10(b). Whole and fractional shares shall be purchased, unless the Committee determines that the purchase of fractional shares is administratively impracticable; any payroll deductions accumulated in a participant’s account and not applied to the purchase of shares shall be retained in the participant’s account and applied in the next Offering Period, subject to withdrawal by the participant pursuant to Section 9.

9. Voluntary Withdrawals; Termination of Employment.

  (a) A Participant may withdraw all but not less than all of the contributions credited to his or her account under the Plan by delivering a notice of withdrawal in the form and manner prescribed by the Committee and in accordance with the Policy of the Company, provided such notice is received no later than one month before the Expiration Date. All of Participant’s contributions credited to his or her account will be paid to him or her not later than sixty (60) days after receipt of his or her notice of withdrawal and his or her Purchase Right for the then current Offering will be automatically terminated, and no further contributions by such Employee for the purchase of Common Stock will be permitted or made during such Offering.

  (b) Upon termination of a Participant’s status as an Eligible Employee prior to the Expiration Date of an Offering for any reason, whether voluntary or involuntary, including retirement or death, the contributions credited to his or her account will be returned to him or her or, in the case of his or her death, to the Participant’s estate, not later than sixty (60) days after the termination of the Participant’s status as an Eligible Employee, and his or her Purchase Right will be automatically terminated.

  (c) A Participant’s voluntary withdrawal from an Offering will not have any effect upon his or her eligibility to participate in a succeeding Offering or in any similar plan that may hereafter be adopted by the Company.

  (d) If a Participant participated in an Offering elects to not participate or is not eligible to participate in the next following Offering, then any contributions credited to his or her Plan account that were not used to purchase shares as of the preceding Offering Period’s Expiration Date will be returned to him or her not later than sixty (60) days after the Grant Date of such next following Offering.
