Payroll deductions will begin as soon as practical, but not later than the first payroll period commencing after receipt and acceptance of a Participant's enrollment form. 8. CONTRIBUTIONS AND PURCHASE OF SHARES Each Participant, in any offering under this Plan, will be granted an option, on the effective date of such offering, for as many whole number Shares of Company stock as may be purchased on the Purchase Date, as hereinafter defined, with the following amounts: A. one percent (1%), two percent (2%), three percent (3%), four percent (4%), or five percent (5%) of Gross Earnings received during the Offering Period or that portion of the Offering Period during which an employee participates in the Plan, which purchase will be paid by payroll deductions during such Offering Period; and B. the balance (if any) carried forward from the Participant's Account for the preceding Offering Period pursuant to the third to the last paragraph of this Section 8. No employee may be granted an option to purchase Shares under this Plan, if (a) the grant of that option permits an employee to purchase Shares under this Plan and any other stock purchase plan of the Company to exceed Twenty-Five Thousand ($25,000.00) of the fair market value of such Stock during any calendar year, or (b) an employee owns five percent (5%) or more of the Stock of the Company immediately after the option is granted. For purposes of subpart (b) in the immediately preceding sentence of this Section 8, the rules of Section 424(d) of the United States Internal Revenue Code shall apply to determine the stock ownership of an individual and stock which the employee may purchase under any option granted pursuant to this Plan shall be treated as stock owned by that employee. The Option Price, paid from each Participant's Account for each Share purchased under this Plan, shall not be less that eighty-five percent (85%) of the fair market value of the Stock as of the last business day of an Offering Period (the "Purchase Date"), the actual percentage to be determined by the Committee. As of the Purchase Date, the Account of each Participant shall be totaled. If such Participant Account contains sufficient funds to purchase one or more full Shares as of that date then the Participant shall be deemed to have purchased such full Share or Shares at the Option Price based on the funds in the Participant's Account. The Participant's Account shall be charged for the amount of the Option Price, the Shares so purchased shall be promptly distributed to the Account of such Participant, and the ownership of such Share or Shares by such Participant, shall be appropriately evidenced on the books of the Company. Subsequent Shares will be purchased in the same manner as of the last day of an Offering Period whenever sufficient funds have again accrued in the Participant's Account. Until Shareholder Approval for this Plan is obtained, any purchase of Shares made pursuant to this Plan shall be deemed a conditional purchase of those Shares. No Participant shall have any rights in any Shares until Shares are purchased on behalf of a Participant. A Participant may change his or her percentage rate of payroll deduction contributions in the Plan subject to the percentage rates permitted herein by filing an amended Enrollment Form with the Company, which amendment will become effective as soon as practical but not later than 45 days after the date such amended Enrollment Form is received by the Company. The amount of the payroll deduction may changed only once during any Offering Period. 5 Any balance remaining in Participant's Account at the end of any Offering Period will be carried forward into the Participant's Account for the following Offering Period. In no event will the balance carried forward be equal to or greater than the Option Price of one Share on the last day of any Offering Period. All options for Shares which have not been exercised at the end of an Offering Period shall terminate on the last day of the Offering Period. If, with respect to an offering of Shares, there is an insufficient number of Shares available to satisfy all outstanding options, then the available Shares shall be allocated to each Participant in the proportion that the funds credited to the Account of each Participant bears to the aggregate funds available in the accounts of all Participants. For the purposes of this Section 8 the phrase "Fair Market Value" shall mean the fair market value of Shares as determined by the Committee consistent with those rules and regulations of the United States Internal Revenue Code used to determine fair market value. No option granted hereunder may be exercised after the expiration of five (5) years from the date such option is granted. 9.
