      addition to the retirement benefit to which Executive is entitled under tax
      qualified retirement plans maintained by Employer (hereinafter collectively

      a retirement benefit under this Agreement, which (except as determined below)

      409A(a)(2)(B)(i) of the Code, any payments under Sections 5(viii)(a) or (b)
      above (including any amount payable under Sections 5(viii)(a) or (b) above
      by
      virtue of Section 5(vii)) due Executive within the six (6) month period
