In the event that the sale is so treated, however, the undersigned desires to make an election to have the receipt of the Common Units taxed under the provisions of Code §83(b) at the time the undersigned acquired the Common Units.

5. The fair market value on February 14, 2004 of the property with respect to which the election is being made, determined without regard to any lapse restrictions and in accordance with Revenue Procedure 93-27: $4,500.00.
