19. Amendment or Termination.
(a) The Board (and the Committee or the Administrator except with respect to the number of shares of Stock available under the Plan under Section 12) may at any time and for any reason terminate or amend the Plan. Except as provided in Section 18 hereof, no such termination can affect options previously granted, provided that an Offering Period may be terminated by the Board of Directors by shortening the Offering Period and accelerating the Exercise Date to a date not prior to the date of such Board action if the Board determines that termination of the Plan is in the best interests of the Company and its stockholders. Except as provided in Section 18 and this Section 19, no amendment may make any change in any option theretofore granted which materially adversely affects the rights of any participant, and any amendment will be subject to the approval of the Companys stockholders not later than one year after Board approval of such amendment if such stockholder approval is required by any federal or state law or regulation or the rules of any stock exchange or automated quotation system on which the Stock may then be listed or quoted, or if such stockholder approval is necessary in order for the Plan to continue to meet the requirements of Section 423 of the Code, and the Board may otherwise, in its discretion, determine to submit any amendment to stockholders for approval.
(b) Without stockholder consent and without regard to whether any participant rights may be considered to have been adversely affected, the 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 withholding in excess of the amount designated by a participant in order to adjust for delays or mistakes in the Companys processing of properly completed withholding elections, establish reasonable waiting and adjustment periods and/or accounting and crediting procedures to ensure that amounts applied toward the purchase of Stock for each participant properly correspond with amounts withheld from the participants Compensation, and establish such other limitations or procedures as the Committee determines in its sole discretion are advisable and consistent with the Plan.
20. Notices. All notices or other communications by a participant to the Company under or in connection with the Plan shall be deemed to have been duly given when received in the form specified by the Company at the location, or by the person, designated by the Company for the receipt thereof.
21. Conditions Upon Issuance of Shares. The Company shall not be obligated to issue shares with respect to an option unless the exercise of such option and the issuance and delivery of such shares pursuant thereto shall comply with all applicable provisions of law, domestic or foreign, including, without limitation, the Securities Act of 1933, as amended, the Securities Exchange Act of 1934, as amended, the rules and regulations promulgated thereunder, and the requirements of any stock exchange or automated quotation system upon which the shares may then be listed or quoted, and shall be further subject to the approval of counsel for the Company with respect to such compliance.
22. Plan Effective Date and Stockholder Approval. The Plan has been adopted by the Board on March 7, 2007, but shall become effective upon approval by the Companys stockholders by a vote sufficient to meet the requirements of Section 423(b)(2) of the Code within 12 months after the date the Plan was adopted and prior to the first Exercise Date. In the event stockholders fail to so approve the Plan, all options granted under the Plan shall be canceled, all payroll deductions shall be refunded, and the Plan shall be terminated.
