Disability Benefit. If the Executive experiences a Disability prior to Separation from Service and Normal Benefit Date, the Employer shall pay the Executive the Deferral Account balance at Disability, plus an additional amount equal to the Contributions remaining to be made in accordance with [Article 2]. This benefit shall be paid in quarterly installments between 2 years and 10 years, at the selection of the Executive, and shall commence the first day of the immediately subsequent quarter following Disability. During the payment period, interest shall be credited on the unpaid portion of the benefit as described in [Section 3.1(b)(ii)]. The quarterly payments shall be amortized in such a way so as to produce equal payments over the remaining payment period. This will require quarterly reamortization for changes in the Crediting Rate.
