Such an agreement may provide for terms and conditions in addition to a guilty plea by the accused in order to be effective.

((2)) A plea agreement under this subsection may not provide for a sentence of death imposed by a military judge alone. A sentence of death may only be imposed by the unanimous vote of all members of a military commission concurring in the sentence of death as provided in .
