funds or portion of the Account in any specific asset, to liquidate any particular investment, or to apply in any specific manner the proceeds from the sale, liquidation, or maturity of any particular investment. The Company assumes no risk of any
decrease in the value of any investment designations made by Participant with respect to the hypothetical investment benchmarks. The Companys sole obligations are to maintain the Participants Account and make payments to the Participant
as herein provided.
