TRANSFERRING YOUR DSUs AND RELATED DIVIDEND EQUIVALENTS. Normally your DSUs and the related dividend equivalents may not be transferred to another person. However, as described in Section 3(f), you may complete a Beneficiary Designation Form to name the person to receive any DSUs and related dividend equivalents that vest before you die but are settled after you die. Also, the Committee may allow you to place your DSUs and dividend equivalents into a trust established for your benefit or the benefit of your family. Contact [Third Party Administrator] at [TPA Telephone Number] or at the address given above if you are interested in doing this.
