      claimant or duty authorized representative fails to request such a
      reconsideration within such sixty (60) day period. it shall be
      conclusively determined for all purposes of this Plan that the denial of

      (60) day period, the claimant or duly authorized representative shall have
      thirty (30) days after filing a request for reconsideration to submit
      additional written material in support of the claim, review pertinent
      documents, and submit issues and comments in writing.

         (b) After such reconsideration request, the Committee shall determine
      within sixty (60) days of receipt of the claimant's request for

      the Committee, the time for the Committee to make a decision may be
      extended by an additional sixty (60) days upon written notice to the
      claimant prior to the commencement of the extension. If such determination
      is favorable to the claimant, it shall be binding and conclusive. If such
      determination is adverse to such claimant, it shall be binding and

      notifies the Committee within ninety (90) days after the mailing or
      delivery to the claimant by the Committee of its determination that
      claimant intends to institute legal proceedings challenging the
      determination of the Committee and actually institutes such legal
      proceedings within one hundred eighty (180) days after such mailing or
      delivery.
