If a person becomes entitled to a distribution from the program under this part that constitutes an eligible rollover distribution within the meaning of Section 401(a)(31) of Title 26 of the United States Code, the person may elect, under terms and conditions established by the board, to have the distribution or a portion thereof paid directly to a plan that constitutes an eligible retirement plan within the meaning of Section 401(a)(31), as specified by that person. Upon the exercise of the election by a person with respect to a distribution or a portion thereof, the distribution from the program of the amount so designated, once distributable under the terms of the program, shall be made in the form of a direct rollover to the eligible retirement plan so specified.
