At Normal Retirement Age, the Disability benefit will be reduced to an annual amount equal to the Normal Retirement Benefit as provided for in Section 4(a) above as if the Executive separated from service at the Executive’s Normal Retirement Age and such reduced amount shall continue in equal monthly installments (1/12^th of the annual benefit) for the remaining portion the Disability Payment Period.

Upon the request of the Plan Administrator, the Executive must submit proof to the Plan Administrator of Social Security Administration’s or the provider’s determination.
