      to such Withholding requirements.  Notwithstanding any
      provision, the Tax Payment shall be deemed paid to the Officer in the
      event the Company notifies the Officer in writing of its intent to pay the
      Tax Payment, concludes that the Company is required to withhold the Tax
      Payment as part of its Withholding obligations, and acts in accordance
      with the its Withholding obligations, the Tax Payment shall be deemed paid
      for purposes of this Agreement.
