In the event that benefits under this Agreement are not paid to the Executive (or to his Beneficiary in the case of the Executive's death) and such claimant feels he is entitled to receive such benefits, then a written claim must be made to the Administrator within 60 days from the date payments are refused.   The Administrator shall review the written claim and, if the claim is denied, in whole or in part, it shall provide in writing, within 90 days of receipt of such claim, its specific reasons for such denial, reference to the provisions of this Agreement upon which the denial is based, and any additional material or information necessary to perfect the claim.   Such writing by the Administrator shall further indicate the additional steps which must be undertaken by claimant if an additional review of the claim denial is desired.
