We will pay a commission to an agent, ranging from 0.125% to 0.750% of the principal amount of a note, depending upon its stated maturity, sold through an agent as our agent. Commissions with respect to notes with stated maturities in excess of 30 years that are sold through an agent will be negotiated between us and such agent at the time of such sale.
