PAYROLL DEDUCTIONS

Section 6.1. Payroll Deductions. At the time an Employee files his or her subscription agreement, he or she shall elect to have payroll deductions made on each pay day during the Offering Period in an amount not exceeding fifteen percent (15%) of the Compensation which he or she receives on each pay day during the Offering Period; provided, however, that should a pay day occur on an Exercise Date, the Employee shall have the payroll deductions made on such day applied to his or her account under the next succeeding Offering Period.

Section 6.2. Crediting of Account. All payroll deductions made for an Employee who has elected to participate in the Plan shall be credited to his or her account under the Plan and shall be withheld in whole percentages only. An Employee who has elected to participate in the Plan may not make any additional payments into such account.

Section 6.3. Discontinuation of Payroll Deductions. An Employee who has elected to participate in the Plan may discontinue his or her participation in the Plan as provided in Article X below, or may increase or decrease the rate of his or her payroll deductions during the Offering Period by completing or filing with the Company a new subscription agreement authorizing a change in payroll deduction rate. The Board may, in its discretion, limit the nature and/or number of participation rate changes during any Offering Period. The change in rate shall be effective with the first full payroll period following five (5) business days after the Company’s receipt of the new subscription agreement unless the Company elects to process a given change in participation more quickly. An Employee’s subscription agreement shall remain in effect for successive Offering Periods unless terminated as provided in Article X below.

Section 6.4. Company Cessation of Payroll Deductions. Notwithstanding the foregoing, to the extent necessary to comply with section 423(b)(8) of the Code and Section 3.2 above, an Employee’s payroll deductions may be decreased to zero percent (0%) at any time during an Offering Period. Payroll deductions shall recommence at the rate provided in such Employee’s subscription agreement at the beginning of the first Offering Period which is scheduled to end in the following calendar year, unless terminated by the Employee as provided in Article X below. At the time the option is exercised, in whole or in part, or at the time some or all of the Company’s Common Stock issued under the Plan is disposed of, the Employee must make adequate provision for the Company’s federal, state, or other tax withholding obligations, if any, which arise upon the exercise of the option or the disposition of the Common Stock. At any time, the Company may, but shall not be obligated to, withhold from an Employee’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 sale or early disposition of Common Stock by the Employee.

ARTICLE VII

On the Enrollment Date of each Offering Period, each eligible Employee who has elected to participate in such Offering Period shall be granted an option to purchase on the Exercise Date

during such Offering Period (at the applicable Purchase Price) up to a number of shares of the Company’s Common Stock determined by dividing such Employee’s payroll deductions accumulated prior to such Exercise Date and retained in the Employee’s account as of the Exercise Date by the applicable Purchase Price; provided that in no event shall an Employee be permitted to purchase on the Exercise Date of any Offering Period more than five thousand (5,000) shares of the Company’s Common Stock (subject to any adjustment pursuant to Article XIX), and provided further that such purchase shall be subject to the limitations set forth in Section 3.2 and Article XIII hereof.

The option shall expire on the last day of the Offering Period if it is not exercised.

No fractional shares shall be purchased; any payroll deductions accumulated in an Employee’s account which are not sufficient to purchase a full share shall be retained in the Employee’s account for the subsequent Offering Period, subject to earlier withdrawal by the Employee as provided in Article X below. Any other monies left over in a Employee’s account after the Exercise Date shall be returned to the Employee. During an Employee’s lifetime, an Employee’s option to purchase shares of Common Stock hereunder is exercisable only by him or her.

Section 8.2. Actions Taken by the Board or the Company.

(a) The Board may take any action described in Section 8.2(b) below, if the Board determines, in its sole and absolute discretion, that, on a given Exercise Date, the number of shares of Common Stock with respect to which options are to be exercised may exceed either the number of shares of Common Stock that are available for sale under the Plan on:

(i) the Enrollment Date of the applicable Offering Period, or

(ii) on such Exercise Date.

(b) If the Board determines, in its sole and absolute discretion, that the events described in Section 8.2(a) above are applicable, the Board may in its sole discretion provide that the Company shall make a pro rata allocation of the shares of Common Stock available for purchase on such Enrollment Date or Exercise Date, as applicable, in as uniform a manner as shall be practicable and as it shall determine in its sole discretion to be equitable among all participating Employees who are exercising options to purchase shares of Common Stock on such Exercise Date.

The Board shall notify each participating Employee in writing, at least ten (10) business days prior to the Dissolution Exercise Date, that the Exercise Date for the Employee’s option has been changed to the Dissolution Exercise Date and that the Employee’s option shall be exercised automatically on the Dissolution Exercise Date, unless prior to such date the Employee has withdrawn from the Offering Period as provided in Article X above.

Except as provided in Article XIX and this Article XX, no amendment may make any change in any option theretofore granted which adversely affects the rights of any participating Employee.

Section 20.2. Modifications. Without stockholders consent and without regard to whether any Employee rights may be considered to have been “adversely affected,” the Board (or its committee) shall be entitled to change the Offering Periods, limit the frequency and/or number of changes in the amount withheld during an Offering Period, establish the exchange ratio applicable to amounts withheld in a currency other than U.S. dollars, permit payroll

10

Section 20.3. Avoidance of Adverse Accounting Consequences.

(a) In the event the Board determines that the ongoing operation of the Plan may result in unfavorable financial accounting consequences, the Board may, in its discretion and, to the extent necessary or desirable and consistent with section 423 of the Code, modify or amend the Plan to reduce or eliminate such accounting consequence including, but not limited to:
