The Option may be exercised only by Participant (or other proper party in the event of death or Disability), subject to the conditions of the Plan and subject to such other administrative rules as the Administrator may deem advisable, by delivering to the Company at its principal office within the option period the Notice of Option Exercise attached hereto as Attachment III (the “Notice of Exercise”) or following the procedures for exercise established by the Administrator. The Notice of Exercise shall be signed by Participant and shall state the number of shares as to which the Option is being exercised. Any exercise shall be accompanied by payment in full of the Exercise Price and any required tax withholding for all Options designated in the Notice of Exercise. The exercise of the Option shall be deemed effective upon receipt of such Notice of Exercise by the Company and upon payment that complies with the terms of the Plan and this Agreement. The Option may be exercised with respect to any number or all of the shares as to which it can then be exercised and, if partially exercised, may be so exercised as to the unexercised portion at any number of times during the option period as provided herein, provided, however, that this Option may not be exercised for a fraction of a share of Common Stock.
